    In February 2008, we alerted the Advisory Committee on Immunization Practices to preliminary evidence of a twofold increased risk of febrile seizures after the combination measles-mumps-rubella-varicella (MMRV) vaccine when compared with separate measles-mumps-rubella (MMR) and varicella vaccines. Now with data on twice as many vaccine recipients, our goal was to reexamine seizure risk after MMRV vaccine. Using 2000-2008 Vaccine Safety Datalink data, we assessed seizures and fever visits among children aged 12 to 23 months after MMRV and separate MMR + varicella vaccines. We compared seizure risk after MMRV vaccine to that after MMR + varicella vaccines by using Poisson regression as well as with supplementary regressions that incorporated chart-review results and self-controlled analyses. MMRV vaccine recipients (83,107) were compared with recipients of MMR + varicella vaccines (376,354). Seizure and fever significantly clustered 7 to 10 days after vaccination with all measles-containing vaccines but not after varicella vaccination alone. Seizure risk during days 7 to 10 was higher after MMRV than after MMR + varicella vaccination (relative risk: 1.98 [95% confidence interval: 1.43-2.73]). Supplementary analyses yielded similar results. The excess risk for febrile seizures 7 to 10 days after MMRV compared with separate MMR + varicella vaccination was 4.3 per 10,000 doses (95% confidence interval: 2.6-5.6). Among 12- to 23-month-olds who received their first dose of measles-containing vaccine, fever and seizure were elevated 7 to 10 days after vaccination. Vaccination with MMRV results in 1 additional febrile seizure for every 2300 doses given instead of separate MMR + varicella vaccines. Providers who recommend MMRV should communicate to parents that it increases the risk of fever and seizure over that already associated with measles-containing vaccines.

    Oncolytic measles and mumps viruses (MeV, MuV) have a potential for anti-cancer treatment. We examined the anti-tumor activity of MeV, MuV, and MeV-MuV combination (MM) against human solid malignancies (HSM). MeV, MuV, and MM targeted and significantly killed various cancer cell lines of HSM but not normal cells. MM demonstrated a greater anti-tumor effect and prolonged survival in a human prostate cancer xenograft tumor model compared to MeV and MuV. MeV, MuV, and MM significantly induced the expression of immunogenic cell death markers and enhanced spleen-infiltrating immune cells. In conclusion, MM combination significantly improves the treatment of human solid malignancies.

    A randomized trial was conducted to assess the immunogenicity and reactogenicity of yellow fever vaccines (YFV) given either simultaneously in separate injections, or 30 days or more after a combined measles-mumps-rubella (MMR) vaccine. Volunteers were also randomized to YFV produced from 17DD and WHO-17D-213 substrains. The study group comprised 1769 healthy 12-month-old children brought to health care centers in Brasilia for routine vaccination. The reactogenicity was of the type and frequency expected for the vaccines and no severe adverse event was associated to either vaccine. Seroconversion and seropositivity 30 days or more after vaccination against yellow fever was similar across groups defined by YFV substrain. Subjects injected YFV and MMR simultaneously had lower seroconversion rates--90% for rubella, 70% for yellow fever and 61% for mumps--compared with those vaccinated 30 days apart--97% for rubella, 87% for yellow fever and 71% for mumps. Seroconversion rates for measles were higher than 98% in both comparison groups. Geometric mean titers for rubella and for yellow fever were approximately three times higher among those who got the vaccines 30 days apart. For measles and mumps antibodies GMTs were similar across groups. MMR's interference in immune response of YFV and YFV's interference in immune response of rubella and mumps components of MMR had never been reported before but are consistent with previous observations from other live vaccines. These results may affect the recommendations regarding primary vaccination with yellow fever vaccine and MMR. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Objective. To compare the incidence of adverse events following the administration of three commercially available measles-mumps-rubella (MMR combination vaccines. Methods. A randomized double-blind clinical trial was performed in 1996 that involved a total of 10 142 students 6-12 years of age in the state of Rio Grande do Sul, in Brazil. An MMR vaccine containing the Edmonston-Zagreb, Leningrad-Zagreb, and RA 27/3 strains ("vaccine A" was administered to 2 226 students (21.9% of the total; an MMR vaccine with the Moraten, Jeryl Lynn, and Wistar 27/3 strains ("vaccine B" was administered to 2 216 children (21.8%; and an MMR vaccine containing the Schwartz, Urabe AM-9, and Wistar 27/3 strains ("vaccine C" was given to 2 179 students (21.5%. A control group of 3 521 students (34.7% was not vaccinated. Both the vaccinated subjects and the control subjects were followed daily for 30 days to detect any clinical manifestations. Results. Adverse events were more frequent in the vaccinated children than in the control group (P < 0.01. In terms of causing parotitis, vaccine A had a relative risk (RR of 5.72 (95% confidence interval (CI = 3.11-10.54 when compared with vaccine B, and an RR of 2.33 (95% CI = 1.52-3.58 when compared with vaccine C. Vaccine A was also associated with an increased risk of lymphadenopathy when compared with vaccine B (RR = 3.11; 95% CI = 1.78-5.45 and with vaccine C (RR = 2.22; 95% CI = 1.35-3.66. Vaccine C was associated with an increased risk of parotitis when compared with vaccine B (RR = 2.46; 95% CI = 1.26-4.80. Three cases of aseptic meningitis were detected among the children in the study group, but only one case of vaccine-related aseptic meningitis was identified, among the children receiving vaccine A. Conclusions. The three MMR vaccines that we studied are associated with different risks of adverse events. We found vaccine A to cause more reactions than the two other vaccines, especially vaccine B. In addition

    The coadministration of the combined meningococcal serogroup C conjugate (MCC)/Haemophilus influenzae type b (Hib) vaccine with pneumococcal conjugate vaccine (PCV7) and measles, mumps, and rubella (MMR) vaccine at 12 months of age was investigated to assess the safety and immunogenicity of this regimen compared with separate administration of the conjugate vaccines. Children were randomized to receive MCC/Hib vaccine alone followed 1 month later by PCV7 with MMR vaccine or to receive all three vaccines concomitantly. Immunogenicity endpoints were MCC serum bactericidal antibody (SBA) titers of ≥8, Hib-polyribosylribitol phosphate (PRP) IgG antibody concentrations of ≥0.15 μg/ml, PCV serotype-specific IgG concentrations of ≥0.35 μg/ml, measles and mumps IgG concentrations of >120 arbitrary units (AU)/ml, and rubella IgG concentrations of ≥11 AU/ml. For safety assessment, the proportions of children with erythema, swelling, or tenderness at site of injection or fever or other systemic symptoms for 7 days after immunization were compared between regimens. No adverse consequences for either safety or immunogenicity were demonstrated when MCC/Hib vaccine was given concomitantly with PCV and MMR vaccine at 12 months of age or separately at 12 and 13 months of age. Any small differences in immunogenicity were largely in the direction of a higher response when all three vaccines were given concomitantly. For systemic symptoms, there was no evidence of an additive effect; rather, any differences between schedules showed benefit from the concomitant administration of all three vaccines, such as lower overall proportions with postvaccination fevers. The United Kingdom infant immunization schedule now recommends that these three vaccines may be offered at one visit at between 12 and 13 months of age.

    A novel measles-mumps-rubella vaccine (Priorix) has been marketed by SmithKline Beecham. It contains live attenuated virus with measles and mumps strains slightly different from those present in MMR VAX (Pasteur Merieux MSD). The indications and contraindications are similar for both vaccines. Immunogenicity is also equivalent as well as general reactogenicity. By contrast local symptoms were reported significantly less frequently after Priorix.

    2016-12-22

    Vaccine-preventable diseases such as measles, mumps, rubella, and varicella continue to plague children and adults worldwide. Although public health programs have helped decrease the prevalence and sequelae of these diseases, outbreaks still occur. To limit the spread of these diseases, emergency clinicians must be able to readily identify the characteristic presentations of the rashes associated with measles, rubella, and varicella, as well as the common presenting features associated with mumps. Diagnostic laboratory studies are not usually necessary, as a complete history and physical examination usually lead to an accurate diagnosis. Treatment for these vaccine-preventable diseases usually consists of supportive care, but, in some cases, severe complications and death may occur. This issue provides a review of the clinical features, differential diagnoses, potential complications, and treatment options for measles, mumps, rubella, and varicella.

  16. Trend of measles, mumps, and rubella incidence following the measles-rubella catch up vaccination in the Republic of Korea, 2001.

    Choe, Young June; Eom, Hye-Eun; Cho, Sung-Il

    2017-09-01

    Following the introduction of measles-rubella (MR) catch-up vaccination in 2001 and two dose measles-mumps-rubella (MMR2) keep-up program in 2002, the incidence of measles, mumps, and rubella was not evaluated systematically. To describe the recent changes in epidemiology, a population-based incidence study from 2001 to 2015 using national notifiable disease surveillance data was conducted. Between 2001 and 2015, there was decrease in the incidence of measles and rubella, whereas a steady increase in mump incidence was noted. The age distribution of mumps cases has shifted to the older age group, whereas rubella became more frequent in younger age group. The incidence of mumps showed an increase in every birth cohorts, except for the decrease in incidence for catch-up vaccination cohort from 131 cases in 2007-2011 to 64 cases per 100 000 in 2012-2015. Continuing in monitoring of mumps and strengthening of the high two-dose MMR vaccination coverage should be taken place in Korea. © 2017 Wiley Periodicals, Inc.

    Evidence-based vaccination policy is important for the global and local efforts of achieving control over measles. In 2007, the first Israeli birth cohort to be twice vaccinated during childhood with Measles-Mumps-Rubella vaccine reached adulthood. In parallel, Israel experienced its largest measles outbreak since 1994. We aimed to assess the seroprevalence of measles IgG antibodies and concordance with rubella and mumps seroprevalence among young Israeli adults born 1988-9 in comparison to previous birth cohorts, in order to inform evidence based prevention policy. We conducted a seroprevalence study of IgG antibodies among 439 Israeli adults born in 1988-9, based on a representative sample of sera collected at age 18-19 upon recruitment to mandatory military service in 2007. In total, 85.7% were seropositive for measles as compared with 95.6% in the 1996 recruitment (P Israel and in other countries.

  20. Mumps vaccine virus strains and aseptic meningitis.

    Bonnet, Marie-Claude; Dutta, Anil; Weinberger, Clement; Plotkin, Stanley A

    2006-11-30

    Mumps immunization can easily be included in national schedules, particularly if combined with measles or measles and rubella vaccines, but debate continues concerning the relative safety of various licensed mumps vaccine strains. The opportunities for control of mumps are also being affected by differences in the cost of the vaccines prepared with different strains of mumps virus. The present report evaluates available data on the association of the Urabe and other strains of mumps vaccine with the occurrence of aseptic meningitis. We also review the comparative immunogenicity and efficacies of the most widely used mumps vaccines in controlled clinical trials and field evaluations, and briefly examine relative cost as it relates to the implementation of national immunization programs. We conclude that extensive experience with the most widely used mumps vaccine strains in many countries has shown that the risk-benefit ratio of live mumps vaccines is highly favourable for vaccination, despite the occasional occurence of aseptic meningitis.

    Full Text Available OBJETIVOS: Apresentar uma revisão atualizada sobre os estudos de eficácia, eventos adversos e esquema vacinal da vacina contra varicela e a nova apresentação combinada com a vacina contra sarampo, caxumba e rubéola. FONTES DOS DADOS: Revisão bibliográfica utilizando a base de dados MEDLINE e LILACS no período de 1999 a 2006. SÍNTESE DOS DADOS: A vacina contra varicela tem uma eficácia entre 70 a 90% contra a infecção e 95 a 98% de proteção contra as formas graves. É uma vacina bem tolerada e pouco reatogênica. Após o seu licenciamento, foram comprovados apenas três casos de transmissão do vírus vacinal de pessoas previamente saudáveis para contatos domiciliares, que desenvolveram doença leve. Apesar das evidências de que a proteção conferida pela vacina pode diminuir com o passar dos anos, ainda não é possível afirmar que seja necessário, no momento, a aplicação de uma segunda dose, tendo em vista a exposição ao vírus selvagem. Após a vacinação universal, as chances de estímulo natural deverão diminuir, e muito provavelmente será necessário a aplicação de doses de reforço. Recentemente foi licenciada a vacina quádrupla viral, um produto combinado com a vacina contra sarampo, caxumba, rubéola e varicela com elevadas taxas de soroconversão. CONCLUSÃO:A vacina contra varicela é recomendada pela Sociedade Brasileira de Pediatria (SBP para as crianças a partir de 1 ano de idade. Esperamos que, em breve, a vacina quádrupla viral esteja disponível no Brasil, pois o uso de vacinas combinadas possibilita uma maior cobertura vacinal.OBJECTIVES: To present an up-to-date review of studies investigating the efficacy, adverse events and vaccination regimens of the varicella vaccine and the new presentation combined with the vaccine for measles, mumps and rubella.

    2012-01-01

    Full Text Available OBJECTIVE: To evaluate viral vaccine antibody levels in children with acute lymphoblastic leukemia after chemotherapy and after vaccine booster doses. METHODS: Antibody levels against hepatitis B, rubella, measles and mumps vaccine antigens were evaluated in 33 children after completing chemotherapy (before and after vaccine booster doses and the results were compared to the data of 33 healthy children matched for gender, age and social class. RESULTS: After chemotherapy, 75.9%, 67.9%, 59.3% and 51.7% of the patients showed low antibody titers that would be unlikely to protect against exposure to measles, rubella, hepatitis B and mumps, respectively. After receiving a vaccine booster dose for these antigens the patients had high antibody levels consistent with potential protection against measles, mumps and hepatitis B, but not against rubella. CONCLUSION: Extra doses of measles-mumps-rubella plus hepatitis B vaccines are recommended in acute lymphoblastic leukemia patients submitted to treatment after hematologic recovery. After this, viral vaccine antibody levels should be verified to define the individual's protective status.

    2012-06-13

    The aim of this study was to investigate the relationship between autism spectrum disorder (ASD) and general vaccinations, including measles-mumps-rubella (MMR) vaccine, in Japanese subjects, a population with high genetic homogeneity. A case-control study was performed. Cases (n=189) were diagnosed with ASD, while controls (n=224) were volunteers from general schools, matched by sex and birth year to cases. Vaccination history and prenatal, perinatal, and neonatal factors from the Maternal and Child Health handbook, which was part of each subject's file, were examined. To determine the relationship between potential risk factors and ASD, crude odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated, and the differences in mean values of the quantitative variables between cases and controls were analyzed using an unpaired t-test. Moreover, MMR vaccination and the effect of the number of vaccine injections were investigated using a conditional multiple regression model. For MMR vaccination, the OR was 1.04 (95% CI, 0.65-1.68), and no significant differences were found for the other vaccines. For all of the prenatal, perinatal and neonatal factors, there were no significant differences between cases and controls. Furthermore, regarding the presence of ASD, MMR vaccination and the number of vaccine injections had ORs of 1.10 (95% CI, 0.64-1.90) and 1.10 (95% CI, 0.95-1.26), respectively, in the conditional multiple regression model; no significant differences were found. In this study, there were not any convincing evidences that MMR vaccination and increasing the number of vaccine injections were associated with an increased risk of ASD in a genetically homogeneous population. Therefore, these findings indicate that there is no basis for avoiding vaccination out of concern for ASD. Copyright © 2012 Elsevier Ltd. All rights reserved.

  5. Overview of measles and mumps vaccine: origin, present, and future of vaccine production.

    Betáková, T; Svetlíková, D; Gocník, M

    2013-01-01

    Measles and mumps are common viral childhood diseases that can cause serious complications. Vaccination remains the most efficient way to control the spread of these viruses. The manufacturing capability for viral vaccines produced in embryonated hen eggs and conventional/classical cell substrates, such as chicken embryo fibroblast or primary dog kidney cell substrates, is no longer sufficient. This limitation can be overcome by utilizing other recognized cell substrates such as Madin Darby Canine Kidney (MDCK), Chinese Hamster Ovary (CHO), Vero (monkey origin) cells, MRC-5 (human diploid) or as an alternative, introducing new cell substrates of human or avian origin. A very important factor in vaccine production is the safety and immunogenicity of the final vaccine, where the proper choice of cell substrate used for virus propagation is made. All substrates used in vaccine production must be fully characterized to avoid the contamination of hidden unknown pathogens which is difficult to achieve in primary cell substrates.

    The current extent of migration poses emerging socio-economic and humanitarian challenges. Little is known on vaccination rates in migrants entering Europe, and the implementation of guidelines for serological testing and vaccination of refugees are pending. We conducted seroprevalence analyses for measles, mumps, rubella and varicella (MMRV) in 678 refugees coming to Germany during the current crisis. The mean age of refugees was 28.8±11.4 years, and 76.1 % of subjects were male. Overall, IgG seronegativity was 7.4 % (95 % CI 5.5-9.6) for measles, 10.2 % (95 % CI 8.0-12.5) for mumps, 2.2 % (95 % CI 1.2-3.4) for rubella, and 3.3 % (95 % CI 1.9-4.9) for varicella. Seropositivity rates were age-dependent with considerably low values in children. For example, overall MMR immunity was 90.9 % (95 % CI 88.8-93.1), but only 73.1 % of minor aged refugees displayed complete seroprevalence against all three diseases, and only 68.9 % of children and adolescents were completely MMRV immune. Our initial data set suggests overall satisfactory MMRV immunity in adult migrants coming to Europe, but the observed low MMRV seroprevalences in refugee children support thorough and prompt vaccination of young migrants entering Europe. Taken together, our data set underlines the urgent need to implement and validate vaccination guidelines for refugee care in the current crisis.

Clinical studies have evaluated DSJIs for vaccine delivery, but most studies have focused on inactivated, subunit, or DNA vaccines. Questions have been raised about possible damage to live attenuated viral vaccines by forces generated during the jet injection process. This study examines the effect of jet injection on the integrity of measles, mumps, and rubella vaccine (MMR), measured by viral RNA content and infectivity. Three models of DSJIs were evaluated, each generating a different ejection force. Following jet injection, the RNA content for each of the vaccine components was measured using RT-qPCR immediately after injection and following passage in Vero cells. Jet injection was performed with and without pig skin as a simulation of human skin. There was little to no reduction of RNA content immediately following jet injection with any of the three DSJIs. Samples passaged in Vero cells showed no loss in infectivity of the measles vaccine following jet injection. Mumps vaccine consistently showed increased replication following jet injection. Rubella vaccine showed no loss after jet injection alone but some infectivity loss following injection through pig skin with two of the devices. Overall, these data demonstrated that forces exerted on a live attenuated MMR vaccine did not compromise vaccine infectivity. The bench model and protocol used in this study can be applied to evaluate the impact of jet injection on other live virus vaccines. Published by Elsevier Ltd.

    Llenas-García, Jara; Rubio, Rafael; Hernando, Asunción; Arrazola, Pilar; Pulido, Federico

    2013-08-01

    A systematic screening for measles, mumps, rubella (MMR) and varicella zoster virus (VZV) in HIV-positive adult immigrants in Spain was evaluated, and factors associated with MMR and VZV vaccines' indication were studied. Every HIV-positive immigrant was tested for VZV and MMR-IgG. MMR vaccine was indicated to patients with lymphocytes CD4+ >200 cells/mm³ and a negative measles-IgG, a negative mumps-IgG and/or a negative rubella-IgG. VZV vaccine was indicated to every VZV-IgG negative patient with CD4+ >400 cells/mm³. In total, 289 patients were screened; seroprevalence was 95.2%, 92.2%, 70.3% and 89.3% for VZV, measles, mumps and rubella IgG, respectively. Having a negative VZV-IgG was statistically associated with coming from sub-Saharan Africa (prevalence ratio [PR]: 6.52; 95% CI: 1.71-24.84; p=0.006), while having secondary education was a protective factor (PR: 0.25; 95% CI: 0.07-0.97; p=0.045). Fourteen patients (4.8%) had indication of VZV vaccine; vaccination was feasible in 21.4% of them at first visit. Eighty-one patients (29.7%) had indication of MMR vaccine, most of them due to mumps-IgG negative (53.1%) or rubella-IgG negative (24.7%). Age Especial attention should be given to immigrant women of childbearing age.

    Multiple outbreaks of vaccine-preventable viral diseases have occurred in professional sports in recent years. Currently, there is no established protocol for vaccination or immunity screening for professional athletes. There are significant differences in the prevalence of inadequate immunity dependent on age, sport, country of birth, and participation in collegiate sports. Cross-sectional cohort study. Level 4. A sample of Major League Baseball (MLB) and National Basketball Association (NBA) players were screened for serologic evidence of immunity to measles, mumps, rubella, and varicella prior to the 2015 and 2016 seasons. The results were designated as adequate (immune) or inadequate (equivocal or nonimmune) based on laboratory criteria. Comparison with an age-matched control group was performed using data from the National Health and Nutrition Examination Survey (NHANES). A total of 98 athletes (62 MLB, 36 NBA) were screened. The prevalence of inadequate immunity for any virus was 35.5% in MLB players and 33.3% in NBA players. There was a significantly greater risk of inadequate immunity to rubella (risk ratio, 6.38; P < 0.01) and varicella (risk ratio, 4.21; P < 0.01) in athletes compared with the age-matched NHANES population. Our analysis did not reveal differences in rates of immunity based on sport, country of birth (US born vs international), or participation in college athletics. There was a lower rate of inadequate immunity to varicella with increasing age (odds ratio, 0.72; P = 0.05). One-third of athletes studied had inadequate immunity to 1 of the 4 viruses tested. Younger players had a significantly greater risk of inadequate immunity to varicella. Birth outside the US and lack of participation in college athletics were not found to influence immunity rates. These results can inform the development of future screening programs to prevent outbreaks of viral infections in professional athletes.

    Full Text Available OBJECTIVE: We evaluated the seroprevalence for measles, mumps, and rubella in school-age children (6-12 years old before and after the administration of three triple combined viral vaccines. METHODS: In two municipal schools of Rio Grande do Sul, Brazil, 692 blood samples were collected before vaccination and 636 samples 21 to 30 days after vaccination during 1996. IgG antibody seropositivity was investigated by enzyme-linked immunosorbent assay (measles and mumps with Enzygnost [Behring, Marburg, Germany]; rubella with Rubenostika [Organon Teknica, Boxtel, the Netherlands]. The vaccines compared were: A: E-Zagreb, L-Zagreb, and Wistar RA 27/3 (Tresivac; B: Moraten, J-Lynn, and Wistar RA 27/3 (M-M-R II; and C: Schwarz, Urabe AM-9, and Wistar RA 27/3 (Trimovax. RESULTS: Before vaccination, 79.2% [95% confidence interval (CI = 76.0%-82.2%] of the samples were positive for measles, 69.4% (95% CI = 65.8%-72.8% for mumps, and 55.4% (95% CI = 51.6%-59.2% for rubella. After vaccination with the A, B, and C vaccines, seropositivity was 100.0%, 99.5%, and 100.0%, respectively for measles; 99.5%, 94.5%, and 92.0% for mumps; and 92.6%, 91.3%, and 88.6% for rubella. CONCLUSIONS: About one-fifth (20.8% of the schoolchildren who could have been vaccinated against measles at age 9 months had levels of antibodies insufficient for protection. In the sample of schoolchildren without previous vaccination against mumps and rubella, high proportions of susceptible levels were found. All vaccines were immunogenic, but vaccine A yielded a seroconversion rate of 99.5% for the mumps component, which was significantly higher than the other two vaccines (P OBJETIVO: Se evaluó la seroprevalencia para sarampión, paperas y rubéola en niños en edad escolar (6-12 años antes y después de la administración de tres vacunas triples antivirales combinadas.

    The first objective of the study was to determine whether there is a relationship between the measles-mumps-rubella (MMR) vaccination and autism in children. The second objective was to examine whether the risk of autism differs between use of MMR and the single measles vaccine. Case-control study. The 96 cases with childhood or atypical autism, aged 2 to 15, were included into the study group. Controls consisted of 192 children individually matched to cases by year of birth, sex, and general practitioners. Data on autism diagnosis and vaccination history were from physicians. Data on the other probable autism risk factors were collected from mothers. Logistic conditional regression was used to assess the risk of autism resulting from vaccination. Assessment was made for children vaccinated (1) Before diagnosis of autism, and (2) Before first symptoms of autism onset. Odds ratios were adjusted to mother's age, medication during pregnancy, gestation time, perinatal injury and Apgar score. For children vaccinated before diagnosis, autism risk was lower in children vaccinated with MMR than in the nonvaccinated (OR: 0.17, 95% CI: 0.06-0.52) as well as to vaccinated with single measles vaccine (OR: 0.44, 95% CI: 0.22-0.91). The risk for vaccinated versus nonvaccinated (independent of vaccine type) was 0.28 (95% CI: 0.10-0.76). The risk connected with being vaccinated before onset of first symptoms was significantly lower only for MMR versus single vaccine (OR: 0.47, 95% CI: 0.22-0.99). The study provides evidence against the association of autism with either MMR or a single measles vaccine.

    Few data are available on the risk of aseptic meningitis following vaccination with the Leningrad-Zagreb (L-Z) strain of mumps vaccine. In 1997 the mumps vaccine was introduced into the state of Rio Grande do Sul in Brazil through mass vaccination with mumps-measles-rubella (MMR), targeting children aged 1-11 years. Five municipalities used exclusively MMR vaccine containing the L-Z strain of mumps. An outbreak of aseptic meningitis was observed shortly after the mass campaign. To estimate the risk of aseptic meningitis associated with this strain, we analysed vaccination and meningitis case surveillance data from the selected municipalities. A case of vaccine-associated aseptic meningitis was defined as one with a pleocytosis of 10-1,500 leukocytes/ml and occurring within 15-35 days after vaccine receipt. We estimated a risk of 2.9 cases per 10,000 doses of L-Z administered, equivalent to 1 case per 3,390 doses administered. The overall risk of aseptic meningitis following the campaign was increased 12.2-fold (95% CI: 6.0-24.7) compared with the same period in 1995-1996. Following the mass campaign, the incidence of mumps declined 93% during 1998-2000. Vaccination with the L-Z strain of mumps vaccine as part of a mass campaign was associated with a significantly increased risk of aseptic meningitis. Decisions about type of mumps vaccine and mumps vaccination strategies must consider vaccine safety issues in addition to other criteria.

    When this trial was initiated, the combined measles, mumps and rubella (MMR) vaccine was licensed for subcutaneous administration in all European countries and for intramuscular administration in some countries, whereas varicella vaccine was licensed only for subcutaneous administration. This study evaluated the intramuscular administration of an MMR vaccine (M-M-RvaxPro) and a varicella vaccine (VARIVAX) compared with the subcutaneous route. An open-label randomised trial was performed in France and Germany. Healthy children, aged 12 to 18 months, received single injections of M-M-RvaxPro and VARIVAX concomitantly at separate injection sites. Both vaccines were administered either intramuscularly (IM group, n = 374) or subcutaneously (SC group, n = 378). Immunogenicity was assessed before vaccination and 42 days after vaccination. Injection-site erythema, swelling and pain were recorded from days 0 to 4 after vaccination. Body temperature was monitored daily between 0 and 42 days after vaccination. Other adverse events were recorded up to 42 days after vaccination and serious adverse events until the second study visit. Antibody response rates at day 42 in the per-protocol set of children initially seronegative to measles, mumps, rubella or varicella were similar between the IM and SC groups for all four antigens. Response rates were 94 to 96% for measles, 98% for both mumps and rubella and 86 to 88% for varicella. For children initially seronegative to varicella, 99% achieved the seroconversion threshold (antibody concentrations of >or= 1.25 gpELISA units/ml). Erythema and swelling were the most frequently reported injection-site reactions for both vaccines. Most injection-site reactions were of mild intensity or small size (vaccines was comparable regardless of administration route. Integration of both administration routes in the current European indications for the two vaccines will now allow physicians in Europe to choose their preferred administration route

    To evaluate the effectiveness of the measles-mumps-rubella (MMR) vaccine in reducing hospitalizations for infectious disease, targeted and not targeted, as well as from respiratory diseases in children in Rome. The cohort was recomposed through record linkage of 2 archives (vaccination register and hospital discharge records. The analysis included 11,004 children. 20.9% did not receive the MMR vaccination, 49% and 30.1% received one and 2 doses. There were no hospitalizations for rubella, 2 for mumps, and 12 for measles. The vaccine was highly protective against measles and mumps hospitalizations (HR = 0.10; 95% CI: 0.03.0.34). Regarding all infectious diseases there were 414 hospitalizations, and the vaccine was protective (HR = 0.29; 95% CI: 0.25 to 0.34). Concerning respiratory diseases, there were 809 admissions (7.4%), and the vaccine was highly protective (HR: 0.18; 95% CI: 0.07 to 0.48). MMR vaccination is effective for the primary prevention of target and not targeted infectious diseases and may also limit hospitalizations for respiratory diseases.

    Intralesional purified protein derivative (PPD) or mumps, measles, rubella (MMR) were not previously compared regarding their efficacy or mechanism of action in treatment of warts. We aimed to compare their efficacy in treatment of multiple warts and investigate their effect on serum interleukin (IL)-4 and IL-12. Thirty patients with multiple warts were included (10 treated with PPD, 10 with MMR, and 10 with normal saline (control)). Injection was done every 3 weeks until clearance or maximum of three treatments. Clinical response of target and distant warts was evaluated. Serum ILs-4 and -12 were assessed before and after treatment. A significantly higher rate of complete response was found in target and distant warts with PPD (60% each) and MMR (80%, 40%, respectively) compared with controls (0%), with no significant difference between both treatments. After treatment, the control group showed the lowest serum IL-12 and IL-4 levels compared with the MMR- and PPD-treated groups with statistically significant difference in between. MMR resulted in a significantly higher serum IL-12 than PPD. With PPD, IL-4 was increased with statistically significant change compared with pretreat-ment level. Intralesional PPD and MMR show comparable efficacy and safety in treatment of multiple warts. Serum ILs-4 and-12 increase following antigen injection. © 2015 Wiley Periodicals, Inc.

    Multiple vaccination visits and administrations can be stressful for infants, parents and healthcare providers. Multivalent combination vaccines can deliver the required number of antigens in fewer injections and clinic visits, while vaccine co-administration can also reduce the number of visits. This non-inferiority study was undertaken to evaluate the feasibility of co-administering a combined measles-mumps-rubella-varicella (MMRV) vaccine with conjugated meningococcal C (MenC) vaccine in a large cohort of healthy Italian toddlers. Healthy subjects aged 13-15months were randomized (2:1:1) to receive single doses of either: co-administered MMRV+MenC at the same visit (MMRV+MenC group); or MMRV followed 42days later by MenC (MMRV group); or MenC followed 42days later by MMRV (MenC group). Blood samples were collected before and 43days after vaccination. Antibody titers against MMRV were measured using ELISA. Functional-anti-meningococcal-serogroup activity (rSBAMenC) was assessed using a serum bactericidal test. Solicited local and general reactions were recorded for up to 4 and 42days post-vaccination, respectively. Non-inferiority of MMRV+MenC to MMRV (post-dose-1 seroconversion rates) and MMRV+MenC to MenC (post-dose-1 seroprotection rates) was achieved if the lower limit (LL) of the 95% confidence interval (CI) for the group difference was ⩾-10% for each antigen. 716 subjects were enrolled in the study. At 42days post-vaccination, the MMRV seroconversion rates were 99.3% (measles), 94.5% (mumps), 100% (rubella) and 99.7% (varicella) in the MMRV+MenC group, and 99.4%, 93.2%, 100% and 100%, respectively, in the MMRV group. The seroprotection rates against rSBA-MenC were 98.3% in the MMRV+MenC group and 99.3% in the MenC group. Non-inferiority was reached for all the vaccine antigens. The safety profiles were as expected for these vaccines. The immune responses elicited by co-administered MMRV+MenC were non-inferior to those elicited by MMRV or MenC alone and

  8. A case-control study of autism and mumps-measles-rubella vaccination using the general practice research database: design and methodology

    Huang Xiangning

    2001-02-01

    Full Text Available Abstract Background An association between mumps-measles-rubella (MMR vaccination and the onset of symptoms typical of autism has recently been suggested. This has led to considerable concern about the safety of the vaccine. Methods A matched case-control study using data derived form the United Kingdom General Practice Research Database. Children with a possible diagnosis of autism will be identified from their electronic health records. All diagnoses will be validated by a detailed review of hospital letters and by using information derived from a parental questionnaire. Ten controls per case will be selected from the database. Conditional logistic regression will be used to assess the association between MMR vaccination and autism. In addition case series analyses will be undertaken to estimate the relative incidence of onset of autism in defined time intervals after vaccination. The study is funded by the United Kingdom Medical Research Council. Discussion Electronic health databases offer tremendous opportunities for evaluating the adverse effects of vaccines. However there is much scope for bias and confounding. The rigorous validation of all diagnoses and the collection of additional information by parental questionnaire in this study are essential to minimise the possibility of misleading results.

    Rubella is a contagious disease that can be very serious, especially in unvaccinated pregnant women. The best way to be protected is getting vaccinated: MMR vaccine is very effective at protecting people against measles, mumps, and rubella, and preventing the complications caused by these diseases. According to PASSI 2012-2015 (the Italian behavioral risk factor surveillance system) in the territory of ex ASL Roma C only 56% of women between 18 and 49 years were immunized against rubella, thanks to vaccination (34%) or past infection detected by rubeotest (22%); 2% was susceptible and 42% of respondents did not know their immune status against rubella. The Italian National Plan for the Elimination of Measles and Congenital Rubella (PNEMoRc) 2010-15 had the aim to reduce the prevalence of rubella susceptibility in young women (<5%), to reduce the prevalence of congenital rubella and to increase MMR vaccination coverage. This plan suggested to promote actions to spread correct information about MMR vaccine in the general population and healthcare workers and to offer this vaccine to susceptible women during every appropriate contact with the Family planning clinics. In order to ensure and monitor these recommendations, a recovery procedure for MMR vaccine was activated in 2015 for women who contacted the health facilities for their first child vaccination. A form was developed in order to collect information about women's immune status against rubella and measles. According to this tool all women who stated they had never been vaccinated for rubella or MMR and/or did not remember vaccination and/or had never had a rubeotest were considered susceptible to rubella. Women susceptible to rubella were invited to undergo vaccination. Data collected during one year activity were recorded and analyzed with Epinfo 7.0 software. We collected 1801 correctly filled forms; 88.6% (1595) of women were evaluated immune to rubella and 11.4% susceptible. The prevalence of

    Mumps outbreaks have been reported among vaccinated populations, and declining mumps vaccine effectiveness (VE) has been suggested as one possible cause. During a large mumps outbreak in New York City, we assessed: (1) VE of measles-mumps-rubella vaccine (MMR) against mumps and (2) risk factors for acquiring mumps in households. Cases of mumps were investigated using standard methods. Additional information on disease and vaccination status of household contacts was collected. Case households completed follow-up phone interviews 78-198 days after initial investigation to ascertain additional cases. Mumps cases meeting the study case definition were included in the analysis. Risk factors for mumps were assessed, and VE was calculated using secondary household attack rates. Three hundred and eleven households with 2176 residents were included in the analysis. The median age of residents was 13 years (range <1-85), and 462 (21.2%) residents met the study mumps case definition. Among 7-17 year olds, 89.7% received one or more doses of MMR vaccine, with 76.7% receiving two doses. Young adults aged 10-14 years (OR=2.4, CI=1.3-4.7) and 15-19 years (OR=2.5, CI=1.3-5.0) were at highest risk of mumps. The overall 2-dose VE for secondary contacts aged five and older was 86.3% (CI 63.3-94.9). The two-dose effectiveness of MMR vaccine against mumps was 86.3%, consistent with other published mumps VE estimates. Many factors likely contributed to this outbreak. Suboptimal MMR coverage in the affected population combined with VE may not have conferred adequate immunity to prevent transmission and may have contributed to this outbreak. Achieving high MMR coverage remains the best available strategy for prevention of mumps outbreaks. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2015-01-01

    In recent years, large mumps outbreaks, involving mainly adolescents and young adults, have re-emerged in several countries. We investigated a large mumps outbreak, evaluated the association between mumps clinical severity (complications, hospitalization) and vaccination status (number of previous measles, mumps and rubella - MMR vaccine doses), and assessed vaccine effectiveness. The first mumps cases emerged in an ultra-orthodox boys' school in Jerusalem and were epidemiologically linked to the mumps outbreak in New York. Overall, 3130 mumps cases were notified in the Jerusalem district during September 2009-August 2011 (median age 13y, 64% males). Most cases were reported from community clinics. Patients with systemic symptoms and/or complications (419, 13.4%) were either hospitalized (n = 79) or treated in an emergency medical center (n = 340). The main complications included orchitis (3.8% males> age 12y) and meningoencephalitis (0.5%). The mumps virus genotype was G5. The distribution of previous MMR vaccine doses (n = 0,1,2) was: 24.8%, 28.3% and 46.9%, respectively. The number of previous vaccine doses was inversely associated with clinical severity. Adjusted values for MMR vaccine effectiveness against complications were estimated as 52.1% (95% CI -4 -78%) for one vaccine dose and 62.7% (95% CI 25.7-81.3%) for 2 doses. The outbreak was characterized by predominance of male students; the majority of whom had been previously vaccinated. The reported complication rate was relatively low. Vaccination status was associated with age and disease severity. The combination of limited mumps vaccine effectiveness and the specific school setting (dense learning and living conditions) probably contributed to the disease spread.

Houve grande discordância quando os antecedentes clínicos ou vacinais para sarampo e caxumba eram negativos: 51,8% e 61,4% destas crianças possuíam anticorpos circulantes. Quanto à rubéola, não foi possível fazer-se tal correlação, pois a maioria das mães não sabia dar informações sobre esta doença, no passado.One hundred and sixty high socio-economic level, 6-12 year old children, attending a primary school, were tested in 1969 for rubella, measles and mumps HI antibodies. A 49.3% positivity for rubella antibodies, 88.2% for measles and 79.4% for mumps were found. A good correlation was observed between a positive history of clinical disease in the past and detectable serum antibodies for measles and mumps (95.3% and 91.7%, respectively. Quite on the contrary was observed when the history of measles and mumps disease or immunization in the past were negative, as 51.8% and 61.4% of these children, respectively, presented antibodies. As regards rubella, no correlation was obtained as the great majority of the parents was unable to give information on this disease in the past.

  13. Attitudinal and demographic predictors of measles-mumps-rubella vaccine (MMR uptake during the UK catch-up campaign 2008-09: cross-sectional survey.

    Katrina Brown

    Full Text Available BACKGROUND AND OBJECTIVE: Continued suboptimal measles-mumps-rubella (MMR vaccine uptake has re-established measles epidemic risk, prompting a UK catch-up campaign in 2008-09 for children who missed MMR doses at scheduled age. Predictors of vaccine uptake during catch-ups are poorly understood, however evidence from routine schedule uptake suggests demographics and attitudes may be central. This work explored this hypothesis using a robust evidence-based measure. DESIGN: Cross-sectional self-administered questionnaire with objective behavioural outcome. SETTING AND PARTICIPANTS: 365 UK parents, whose children were aged 5-18 years and had received <2 MMR doses before the 2008-09 UK catch-up started. MAIN OUTCOME MEASURES: Parents' attitudes and demographics, parent-reported receipt of invitation to receive catch-up MMR dose(s, and catch-up MMR uptake according to child's medical record (receipt of MMR doses during year 1 of the catch-up. RESULTS: Perceived social desirability/benefit of MMR uptake (OR = 1.76, 95% CI = 1.09-2.87 and younger child age (OR = 0.78, 95% CI = 0.68-0.89 were the only independent predictors of catch-up MMR uptake in the sample overall. Uptake predictors differed by whether the child had received 0 MMR doses or 1 MMR dose before the catch-up. Receipt of catch-up invitation predicted uptake only in the 0 dose group (OR = 3.45, 95% CI = 1.18-10.05, whilst perceived social desirability/benefit of MMR uptake predicted uptake only in the 1 dose group (OR = 9.61, 95% CI = 2.57-35.97. Attitudes and demographics explained only 28% of MMR uptake in the 0 dose group compared with 61% in the 1 dose group. CONCLUSIONS: Catch-up MMR invitations may effectively move children from 0 to 1 MMR doses (unimmunised to partially immunised, whilst attitudinal interventions highlighting social benefits of MMR may effectively move children from 1 to 2 MMR doses (partially to fully immunised. Older children may be

    Egg allergy is one of the most common food allergies during childhood along with cow's milk allergy. The measles-mumpsrubella (MMR) vaccine is included in the pediatric immunization schedule and contains egg protein. The currently accepted opinion is that the MMR vaccination should be done in a single dose under medical observation in patients with egg allergy. Although it is reported that the MMR vaccine is safe for that patients, there are some patients who developed anaphylaxis. Generally, the development of anaphylaxis after the previous vaccination is reported as a contraindication. We present a successful administration of MMR vaccine by gradually increased doses for a patient who developed anaphylaxis after the previous vaccination. Sociedad Argentina de Pediatría.

  15. Evaluation of a Mobile Phone-Based Intervention to Increase Parents' Knowledge About the Measles-Mumps-Rubella Vaccination and Their Psychological Empowerment: Mixed-Method Approach.

    2018-03-07

    There is mixed evidence on the effectiveness of vaccination-related interventions. A major limitation of most intervention studies is that they do not apply randomized controlled trials (RCTs), the method that, over the last 2 decades, has increasingly been considered as the only method to provide proof of the effectiveness of an intervention and, consequently, as the most important instrument in deciding whether to adopt an intervention or not. This study, however, holds that methods other than RCTs also can produce meaningful results. The aim of this study was to evaluate 2 mobile phone-based interventions aimed at increasing parents' knowledge of the measles-mumps-rubella (MMR) vaccination (through elements of gamification) and their psychological empowerment (through the use of narratives), respectively. The 2 interventions were part of an RCT. We conducted 2 studies with the RCT participants: a Web-based survey aimed at assessing their rating of the tool regarding a number of qualities such as usability and usefulness (N=140), and qualitative telephonic interviews to explore participants' experiences with the app (N=60). The results of the survey showed that participants receiving the knowledge intervention (alone or together with the empowerment intervention) liked the app significantly better compared with the group that only received the empowerment intervention (F 2,137 =15.335; Pbenefits of the vaccination at the same time.

    We describe a rare case of fatal mumps encephalomyelitis occurring in 19-year old male following matched unrelated donor peripheral blood haematopoietic stem cell transplantation (HSCT). The indication for HSCT was for an undefined form of severe combined immunodeficiency (SCID). Molecular typing of the mumps viral RNA isolated from neural tissue indicated that the infection was acquired at the time of a mumps outbreak in England and Wales that occurred between 2004 and 2006. This case highlights the importance of considering mumps in the differential diagnosis of central nervous system infection in highly immunosuppressed patients. Copyright © 2013 Elsevier B.V.

    2015-04-01

    Each year in France, varicella and zoster affect large numbers of children and adults, resulting in medical visits, hospitalizations for varicella- and zoster-related complications, and societal costs. Disease prevention by varicella vaccination is feasible, wherein a plausible option involves replacing the combined measles, mumps, and rubella (MMR) vaccine with the combined MMR and varicella (MMRV) vaccine. This study aimed to: (1) assess the cost-effectiveness of adding routine varicella vaccination through MMRV, using different vaccination strategies in France; and (2) address key uncertainties, such as the economic consequences of breakthrough varicella cases, the waning of vaccine-conferred protection, vaccination coverage, and indirect costs. Based on the outputs of a dynamic transmission model that used data on epidemiology and costs from France, a cost-effectiveness model was built. A conservative approach was taken regarding the impact of varicella vaccination on zoster incidence by assuming the validity of the hypothesis of an age-specific boosting of immunity against varicella. The model determined that routine MMRV vaccination is expected to be a cost-effective option, considering a cost-effectiveness threshold of €20,000 per quality-adjusted life-year saved; routine vaccination was cost-saving from the societal perspective. Results were driven by a large decrease in varicella incidence despite a temporary initial increase in the number of zoster cases due to the assumption of exogenous boosting. In the scenario analyses, despite moderate changes in assumptions about incidence and costs, varicella vaccination remained a cost-effective option for France. Routine vaccination with MMRV was associated with high gains in quality-adjusted life-years, substantial reduction in the occurrences of varicella- and zoster-related complications, and few deaths due to varicella. Routine MMRV vaccination is also expected to provide reductions in costs related to

    Vaccination against mumps, introduced initially as recommended, from 2003 is mandatory in Poland and given as two dose scheme with MMR vaccine (mumps, measles, and rubella). Despite observed decline in mumps incidence for over a decade which is a result of conducted vaccinations, mumps is still a common childhood disease in Poland. To assess epidemiological situation of mumps in Poland in 2012, including vaccination coverage in Polish population, in comparison to previous years. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012" (Czarkowski MP i in., Warszawa 2013, NIZP-PZH i GIS). Mumps cases were classified according to the criteria of surveillance case definition implemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC). National Immunisation Programme for year 2012 was also used. In total, there were 2779 mumps cases registered in Poland in 2012. Incidence of mumps was 7.2 per 100 000 and it was higher by 7.5% in comparison with 2011 and lower by 19.4% in comparison to median for the years 2006-2010. The highest incidence rate was observed among children aged 5 years (71.8 per 100 000). Incidence in women (5.9) was lower than in men (8.6). In 2012, 25 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2012 was 97.9%. Systematic execution of mumps vaccination in accordance with the National Immunisation Programme resulted in a significant decrease in the number of registered cases. Due to the high vaccination coverage further decline in the number of cases is expected.

Mumps cases were classified according to the criteria of surveillance case definition implemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC). National Immunisation Programme for year 2013 was also used. In total, there were 2 436 mumps cases registered in Poland in 2013. Incidence of mumps was 6.3 per 100,000 and it was lower by 12.5% in comparison with 2012 and lower by 18.2% in comparison with median for the years 2007-2010. The highest incidence rate was observed among children aged 5 years (54.0 per 100,000). Incidence in men (7.5) was higher than in women (5.2). In 2013, 38 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2013 was 97.5% and it was lower by 0.4% in comparison with year 2012. Systematic execution of mumps vaccination in accordance with the National Immunisation Programme resulted in a significant decrease in the number of registered cases. Due to the high vaccination coverage further decline in the number of cases is expected.

    Routine childhood vaccination against measles, mumps and rubella has virtually abolished virus-related morbidity and mortality. Notwithstanding this, we describe here devastating neurological complications associated with the detection of live-attenuated mumps virus Jeryl Lynn (MuV JL5 ) in the brain of a child who had undergone successful allogeneic transplantation for severe combined immunodeficiency (SCID). This is the first confirmed report of MuV JL5 associated with chronic encephalitis and highlights the need to exclude immunodeficient individuals from immunisation with live-attenuated vaccines. The diagnosis was only possible by deep sequencing of the brain biopsy. Sequence comparison of the vaccine batch to the MuV JL5 isolated from brain identified biased hypermutation, particularly in the matrix gene, similar to those found in measles from cases of SSPE. The findings provide unique insights into the pathogenesis of paramyxovirus brain infections.

    The largest reported mumps outbreak at a US college in 19 years occurred in 2006 at a Kansas university with a 2-dose measles-mumps-rubella (MMR) vaccination policy. We assessed vaccine performance and mumps risk factors, including the possibility of waning vaccine protection. Case students were compared with a cohort of the university's approximately 19,000 undergraduates. The secondary attack rate for clinical mumps was determined among roommates exposed to case students. Time from receipt of the second dose of MMR vaccine was compared between case students and roommates without mumps. Coverage with > or =2 dose of MMR vaccine was > or =95% among 140 undergraduate case students and 444 cohort students. The secondary attack rate for clinical mumps among roommates who had received 2 doses of vaccine ranged from 2.2% to 7.7%, depending on the case definition. Compared with roommates without mumps, case students were more likely (odds ratio, 2.46; 95% confidence interval, 1.25-4.82) to have received their second dose of MMR vaccine > or =10 years earlier. The odds of being a case student increased with each 1-year increase in time from receipt of the second dose of MMR vaccine (odds ratio, 1.36; 95% confidence interval, 1.10-1.68) among case students and roommates aged 18-19 years but not among those aged > or =20 years. Students aged 18-19 years had a higher risk of mumps (risk ratio, 3.14; 95% confidence interval, 1.60-6.16), compared with students aged > or =22 years; women living in dormitories had increased risk of mumps (risk ratio, 1.95; 95% confidence interval, 1.01-3.76), compared with men not living in dormitories. High 2-dose MMR coverage protected many students from developing mumps but was not sufficient to prevent the mumps outbreak. Vaccine-induced protection may wane. Similar US settings where large numbers of young adults from wild-type naive cohorts live closely together may be at particular risk for mumps outbreaks.

    This phase III clinical trial was conducted to evaluate the immunogenicity and safety of the single-dose and multi-dose formulations of a novel MMR vaccine (live, freeze-dried) developed by M/s Cadila Healthcare Limited, India (Cadila MMR vaccine), containing the Hoshino mumps strain, compared to that of an existing MMR vaccine (live, freeze-dried) developed by M/s Serum Institute of India Limited, India (Serum MMR vaccine). These two vaccines have similar measles and rubella strains, but different mumps strains (Hoshino in Cadila MMR vaccine, and L-Zagreb in Serum MMR vaccine). Three hundred and twenty-eight subjects of either sex, aged 15-18 months, were randomized in a 2:1 ratio to receive either the Cadila or Serum MMR vaccine. Immunogenicity assessments (IgG antibodies against measles, mumps, and rubella viruses) were done at baseline and 42 d after vaccination. Solicited (local and systemic) and unsolicited adverse events were recorded for up to 42 d following vaccination. The Cadila MMR vaccine was found to be non-inferior to the Serum MMR vaccine in terms of end-of-study proportion of subjects seropositive for anti-measles antibodies (100.0% in both groups), anti-mumps antibodies (94.5% vs. 94.0%), and anti-rubella antibodies (95.5% vs. 91.0%). Both vaccines were well tolerated by all study participants; the most common adverse event reported in both groups was fever, followed by rash. The results of this phase III clinical trial show that the novel Cadila MMR vaccine is non-inferior to the Serum MMR vaccine.

    An earlier study established that Upper Volta children respond to vaccination with the Enders live attenuated measles strain in the same general fashion as do children in the USA. The present report describes a second pilot project carried out in Ouagadougou, Upper Volta. During this investigation various mixtures of live measles, smallpox and 17D yellow fever vaccines were introduced into susceptible infants by jet injection. Combining the attenuated virus vaccines did not alter or accentuate the characteristic clinical reactions elicited by the individual components, nor was there evidence of significant immunological interference. From this experience it is concluded that combined vaccination with these agents may be safely and effectively employed in larger programmes as the need dictates.

  5. Is it Right Time to Introduce Mumps Vaccine in Indias Universal Immunization Program?

    Vaidya, S R; Hamde, V S

    2016-06-08

    Measles, mumps and rubella are vaccine preventable diseases. However, morbidity and mortality due to these diseases remain largely unnoticed in India. Measles has received much attention; mumps and rubella still need to garner attention. According to the World Health Organization, near-elimination of mumps could be achieved by maintaining high vaccine coverage using a two-dose strategy. However, Government of India has not yet decided on mumps vaccine. In this review, we have reviewed sero-prevalence studies, vaccine studies, outbreak investigations, virus isolation and virus genotyping studies on mumps. Overall, mumps seems to be a significant public health problem in India, but does not garner attention due to the absence of a surveillance and documentation system. Thus, inclusion of mumps antigen in the Universal immunization program would have added advantages, the economic burden imposed by the cost of the vaccine offset by a reduction in disease burden.

    2014-06-01

    Full Text Available A non-controlled longitudinal study was conducted to evaluate the combined vaccine against measles, mumps and rubella (MMR immunogenicity in 150 children vaccinated in the routine of three health units in the city of Rio de Janeiro, Brazil, 2008-2009, without other vaccines administered during the period from 30 days before to 30 days after vaccination. A previous study conducted in Brazil in 2007, in 1,769 children ranging from 12-15 months of age vaccinated against yellow fever and MMR simultaneously or at intervals of 30 days or more between doses, had shown low seroconversion for mumps regardless of the interval between administration of the two vaccines. The current study showed 89.5% (95% confidence interval: 83.3; 94.0 seroconversion rate for mumps. All children seroconverted for measles and rubella. After revaccination, high antibody titres and seroconversion rates were achieved against mumps. The results of this study and others suggest that two MMR doses confer optimal immunoresponses for all three antigens and the possible need for additional doses should be studied taking into account not only serological, but also epidemiological data, as there is no serological correlate of protection for mumps.

    To estimate the mumps vaccine effectiveness (VE) during a large genotype D mumps outbreak, we conducted a cross-sectional study in eight primary schools and associated households in the Netherlands. Questionnaires were used to collect information on the occurrence of mumps. Multivariate analyses were used to estimate VE. Among schoolchildren we estimated the VE against mumps. Among household contacts where the schoolchild was the index case we estimated the VE against mumps and against mumps infectiousness. In total 1175 children and 2281 household contacts participated in the study. The mumps attack rate among schoolchildren was 17%. The mumps VE in schoolchildren was 92% [95% confidence interval (CI) 83-96%] and 93% [85-97%] for one and two doses of the measles, mumps, rubella (MMR) vaccine, respectively. The adjusted mumps VE among household contacts was 67% [65-95%] and 11% [-4 to 88%] against mumps and mumps infectiousness, respectively. Our study indicates that the mumps component of the MMR vaccine offered adequate protection against mumps among schoolchildren. The relatively low VE among household contacts is of concern.

    McLean, D. M.; Bach, Ruth D.; Larke, R. P. B.; McNaughton, G. A.

    1964-01-01

    Between January and June 1963, 45 children were hospitalized with mumps meningoencephalitis. Of 39 patients with laboratory evidence of mumps infection, 24 had parotitis and 15 showed no salivary gland involvement. Cerebrospinal fluids from 18 of 40 patients yielded mumps virus by inoculation of rhesus monkey kidney cultures; 33 subjects, including 12 of the 18 virus excretors, showed rising or elevated levels of mumps antihemagglutinin during convalescence. Between May 1959 and June 1963, mumps virus was recovered from cerebrospinal fluids of 50 of 126 cases of mumps meningoencephalitis; virus isolation rates were highest during the peak incidence of mumps meningoencephalitis in winter and early spring. Mumps vaccine (inactivated) was administered to 34 parents with no history of mumps, shortly after their children developed mumps. Mumps occurred in three of 17 parents without prevaccination mumps antihemagglutinins, and in two others, but in none of 15 who had prevaccination antibodies. PMID:14120950

  9. Mumps and mumps vaccine: a global review.

    Galazka, A M; Robertson, S E; Kraigher, A

    1999-01-01

    Mumps is an acute infectious disease caused by a paramyxovirus. Although the disease is usually mild, up to 10% of patients can develop aseptic meningitis; a less common but more serious complication is encephalitis, which can result in death or disability. Permanent deafness, orchitis, and pancreatitis are other untoward effects of mumps. Based on data reported to WHO up to April 1998, mumps vaccine is routinely used by national immunization programmes in 82 countries/areas: 23 (92%) of 25 developed countries, 19 (86%) of 22 countries with economies in transition (mainly the Newly Independent States of the former Soviet Union), and 40 (24%) of 168 developing countries. Countries that have achieved high coverage have shown a rapid decline in mumps morbidity. Furthermore, in many of these countries, mumps-associated encephalitis and deafness have nearly vanished. This review considers the disease burden due to mumps; summarizes studies on the immunogenicity, efficacy, and safety of different strains of mumps vaccine; and highlights lessons learned about implementing mumps immunization in different countries. Countries already using mumps vaccine should monitor immunization coverage and establish routine mumps surveillance with investigation of outbreaks. Where mumps is targeted for elimination, countries need to add a second dose of mumps vaccine for children, keeping in mind that the disease may still occur in susceptible adults.

The likely epidemiological sources of the transmitted mumps virus were children who were recently vaccinated with the mumps vaccine containing Leningrad-Zagreb or Leningrad-3 MuV. The etiology of the described cases of the horizontal transmission of both mumps vaccine viruses was confirmed by PCR with the sequential restriction analysis.

    sensibilización por algún componente residual de la vacuna y posible reacción cruzada con el dextrano.A case-control study was carried out aiming to describe the cases and causes of anaphylaxis associated with the vaccine against measles, mumps and rubella. A total of 22 reported cases in children who showed mucocutaneous manifestations, during the Campanha Nacional de Vacinação (Brazilian Vaccination Campaign, conducted in the city of Curitiba, Southern Brazil, in 2004, were studied. In addition, 66 children, who were next to these cases and did not show a symptomatology after the vaccine was applied, were selected. Serum measurements of antibodies for vaccine antigens and total IgE, specific IgE antibody measurements for several allergens, and skin tests were performed. Vaccine response was adequate, specific IgE measurement and skin tests showed that potential allergens in vaccines and atopy were not associated with anaphylactic reactions. Skin tests with the vaccine and dextran were positive in the cases exclusively, suggesting sensitization to certain residual components of the vaccine and possible cross-reaction with dextran.

    We report 3 cases of orchitis following vaccination with mumps-measles-rubella (MMR) vaccine, two with an onset within 3 days following vaccination. Orchitis is a common complication of mumps infection, particularly in post-pubertal males, and is also recognized as a very rare complication of mumps vaccination. These cases, discussed together with a comprehensive review of the existing literature regarding post-vaccine orchitis, highlight uncertainty regarding the pathogenesis of post-vaccine orchitis.

    The widespread use of a second dose of mumps vaccine among U.S. schoolchildren beginning in 1990 was followed by historically low reports of mumps cases. A 2010 elimination goal was established, but in 2006 the largest mumps outbreak in two decades occurred in the United States. We examined national data on mumps cases reported during 2006, detailed case data from the most highly affected states, and vaccination-coverage data from three nationwide surveys. A total of 6584 cases of mumps were reported in 2006, with 76% occurring between March and May. There were 85 hospitalizations, but no deaths were reported; 85% of patients lived in eight contiguous midwestern states. The national incidence of mumps was 2.2 per 100,000, with the highest incidence among persons 18 to 24 years of age (an incidence 3.7 times that of all other age groups combined). In a subgroup analysis, 83% of these patients reported current college attendance. Among patients in eight highly affected states with known vaccination status, 63% overall and 84% between the ages of 18 and 24 years had received two doses of mumps vaccine. For the 12 years preceding the outbreak, national coverage of one-dose mumps vaccination among preschoolers was 89% or more nationwide and 86% or more in highly affected states. In 2006, the national two-dose coverage among adolescents was 87%, the highest in U.S. history. Despite a high coverage rate with two doses of mumps-containing vaccine, a large mumps outbreak occurred, characterized by two-dose vaccine failure, particularly among midwestern college-age adults who probably received the second dose as schoolchildren. A more effective mumps vaccine or changes in vaccine policy may be needed to avert future outbreaks and achieve the elimination of mumps. Copyright 2008 Massachusetts Medical Society.

  16. Mumps Virus: Modification of the Identify-Isolate-Inform Tool for Frontline Healthcare Providers

    Kristi L. Koenig

    2016-09-01

    Full Text Available Mumps is a highly contagious viral infection that became rare in most industrialized countries following the introduction of measles-mumps-rubella (MMR vaccine in 1967. The disease, however, has been re-emerging with several outbreaks over the past decade. Many clinicians have never seen a case of mumps. To assist frontline healthcare providers with detecting potential cases and initiating critical actions, investigators modified the “Identify-Isolate-Inform” tool for mumps infection. The tool is applicable to regions with rare incidences or local outbreaks, especially seen in college students, as well as globally in areas where vaccination is less common. Mumps begins with a prodrome of low-grade fever, myalgias and malaise/anorexia, followed by development of nonsuppurative parotitis, which is the pathognomonic finding associated with acute mumps infection. Orchitis and meningitis are the two most common serious complications, with hearing loss and infertility occurring rarely. Providers should consider mumps in patients with exposure to a known case or international travel to endemic regions who present with consistent signs and symptoms. If mumps is suspected, healthcare providers must immediately implement standard and droplet precautions and notify the local health department and hospital infection control personnel.

    For administration of multiple live attenuated vaccines, the Advisory Committee on Immunization Practices recommends either simultaneous immunization or period of at least 28days between vaccines, due to a possible reduction in the immune response to either vaccine. The main objective of this study was to compare the immune response to measles (alone or combined with mumps and rubella) and yellow fever vaccines among infants aged 6-24months living in a yellow fever non-endemic country who had receivedmeasles and yellow fever vaccines before travelling to a yellow fever endemic area. A retrospective, multicenter case-control study was carried out in 7 travel clinics in the Paris area from February 1st 2011 to march 31, 2015. Cases were defined as infants immunized with the yellow fever vaccine and with the measles vaccine, either alone or in combination with mumps and rubella vaccine, with a period of 1-27days between each immunization. For each case, two controls were matched based on sex and age: a first control group (control 1) was defined as infants having received the measles vaccine and the yellow fever vaccine simultaneously; a second control group (control 2) was defined as infants who had a period of more than 27days between receiving the measles vaccine and yellow fever vaccine. The primary endpoint of the study was the percentage of infants with protective immunity against yellow fever, measured by the titer of neutralizing antibodies in a venous blood sample. One hundred and thirty-one infants were included in the study (62 cases, 50 infants in control 1 and 19 infants in control 2). Of these, 127 (96%) were shown to have a protective titer of yellow fever antibodies. All 4 infants without a protective titer of yellow fever antibodies were part of control group 1. The measles vaccine, alone or combined with mumps and rubella vaccines, appears to have no influence on humoral immune response to the yellow fever vaccine when administered between 1 and 27

    Glioblastoma (GBM) is the most common primary malignant brain tumor and has a dismal prognosis. Measles virus (MV) therapy of GBM is a promising strategy due to preclinical efficacy, excellent clinical safety, and its ability to evoke antitumor pro-inflammatory responses. We hypothesized that combining anti- programmed cell death protein 1 (anti-PD-1) blockade and MV therapy can overcome immunosuppression and enhance immune effector cell responses against GBM, thus improving therapeutic outcome. In vitro assays of MV infection of glioma cells and infected glioma cells with mouse microglia ± aPD-1 blockade were established to assess damage associated molecular pattern (DAMP) molecule production, migration, and pro-inflammatory effects. C57BL/6 or athymic mice bearing syngeneic orthotopic GL261 gliomas were treated with MV, aPD-1, and combination treatment. T2* weighted immune cell-specific MRI and fluorescence activated cell sorting (FACS) analysis of treated mouse brains was used to examine adaptive immune responses following therapy. In vitro, MV infection induced human GBM cell secretion of DAMP (high-mobility group protein 1, heat shock protein 90) and upregulated programmed cell death ligand 1 (PD-L1). MV infection of GL261 murine glioma cells resulted in a pro-inflammatory response and increased migration of BV2 microglia. In vivo, MV+aPD-1 therapy synergistically enhanced survival of C57BL/6 mice bearing syngeneic orthotopic GL261 gliomas. MRI showed increased inflammatory cell influx into the brains of mice treated with MV+aPD-1; FACS analysis confirmed increased T-cell influx predominantly consisting of activated CD8+ T cells. This report demonstrates that oncolytic measles virotherapy in combination with aPD-1 blockade significantly improves survival outcome in a syngeneic GBM model and supports the potential of clinical/translational strategies combining MV with αPD-1 therapy in GBM treatment. © The Author(s) 2016.

  19. Measles epidemic in Switzerland and other parts of Europe

    TIS Commission

    2008-01-01

    There has been a measles epidemic in Switzerland since November 2006. By April 2008 the number of cases had reached almost 2500, with over 1300 since the beginning of the year alone. All cantons are affected but to varying degrees, the largest number of cases occurring in the north and east of the country. In all cases, the low vaccination coverage is responsible for the spread of this highly contagious disease. The contagious period starts 4 days before the rash appears and lasts until 4 days afterwards. In the event of infection, children must be kept away from school and measures must be taken to protect those who come into contact with them, which may include vaccination if the infection is less than 72 hours old. The Swiss and international health authorities recommend the following measures to prevent the spread of the disease: those who have already contracted the disease, received 2 doses of the vaccine (often in the form of the combined MMR - measles, mumps, rubella...

    Full Text Available The data on the current vaccination process and specific antibody in 212 children with pathology of nervous systems in age from 1 year to 6 years old, vaccinated against measles. The comparison group consisted of 36 children without neurological disease. 86 children (40,6% were vaccinated measlesmumps vaccine, and 126 children (59,4% only measles vaccine. Post-vaccination period in 77,8% immunized against measles, was uneventful, layering intercurrent infections was noted in 22,2% of vaccine’s, and demonstrated the development of viral respiratory infections, bronchitis, otitis media and exacerbation of underlying disease. It is shown that the level of specific antibody to measles in children with pathology of nervous systems at 30 days after vaccination was 5,04±0,16 log 2, which did not differ from the comparison group (5,88±0,31 log 2. No significant differences in the level of antibody in a smooth and complicated course of vaccination period were found. Immunization of children with disorders of the nervous system of live vaccines is quite effective and leads to the formation of protective antibody titers in all vaccinated.

    Healthcare personnel (HCP) play an important role in transmission of highly contagious diseases such as measles. Current immunization guidelines in Catalonia include Measles-Mumps-Rubella (MMR) immunization for HCP born after 1967 without evidence of immunity. Despite high vaccination coverage (90%) a high burden of measles cases related to outbreaks have occurred. The aim of this study was to assess the implication of HCP in measles transmission related to healthcare setting. A review of surveillance case data from 2001 to 2013 gathered through the Measles Elimination Program in Catalonia was performed. Twenty six outbreaks involving 797 cases were reported, 52 (6.5%) were HCP aged 21–41 years, 72,5% (38) patient were care personnel (doctors and nurses) and 22,5% (14) other health care related personnel. Forty six 87%) were unvaccinated, 4(10%) had only one dose and 2 had two doses of MMR. In community outbreaks 30 clusters with HCP involved were observed, yet none were identified as index cases. Non-vaccinated HCPs against measles were all under 45 years of age. Vaccination is the only reliable protection against nosocomial spread of measles from HCPs. Assessing vaccination status of HCPs and implementing a 2 dose vaccination in those lacking evidence of immunity is needed in order to set to zero the risk of acquiring and spreading measles in healthcare (HC) settings.

    1971-01-01

    The results of the launching of two-Marshall-University of Michigan Probes (MUMP 9 and MUMP 10), Nike-Tomahawk sounding rocket payloads, are summarized. The MUMP is similar to the thermosphere probe, an ejectable instrument package for studying the variability of the earth's atmospheric parameters. The MUMP 9 payload included an omegatron mass analyzer, a molecular fluorescence densitometer, a mini-tilty filter, and a lunar position sensor. This complement of instruments permitted the determination of the molecular nitrogen density and temperature in the altitude range from approximately 143 to 297 km over Wallops Island, Virginia, during January 1971. The MUMP 10 payload included an omegatron mass analyzer, an electron temperature probe, a cryogenic densitometer, and a solar position sensor. These instruments permitted the determination of the molecular nitrogen density and temperature and the charged particle density and temperature in the altitude range from approximately 145 to 290 km over Wallops Island during the afternoon preceding the MUMP 9 launch.

    To evaluate the immunogenicity and safety of a reduced antigen diphtheria-tetanus-acellular pertussis-inactivated poliovirus (dTap-IPV B ) vaccine (Boostrix-IPV, GSK) as a pre-school booster in 3-4 year old children as compared to dTap-IPV R (Repevax, Sanofi Pasteur), when co-administered with mumps-measles-rubella vaccine (MMRV). This phase III, open label, randomised study was conducted in the UK between April 2011 and April 2012. Children due their pre-school dTap-IPV booster vaccination were randomised 2:1 to receive one of two different dTap-IPV vaccines (dTap-IPV B or dTap-IPV R ) with blood sample for immunogenicity assessment just prior and one month after vaccination. Immune responses to diphtheria, tetanus and polio antigens were compared between the study vaccines (inferential comparison). In the absence of an accepted pertussis correlate of protection, the immunogenicity of dTap-IPV B vaccine against pertussis was compared with historical pertussis efficacy data (inferential comparison). Safety and reactogenicity of both study vaccines were evaluated. 387 children were randomised and 385 vaccinated: 255 in the dTap-IPV B group and 130 in the dTap-IPV R group. Prior to vaccination, ≥76.8% of children had anti-diphtheria and ≥65.5% had anti-tetanus titres above the protection threshold; for pertussis, the pre-vaccination seropositivity rate ranged between 18.1 and 70.6%. Both vaccines were immunogenic with 99.2-100% of children achieving titres above the pre-specified seroprotection/seropositivity thresholds. One serious adverse event not considered as causally related to the study vaccination by the study investigator was reported in the dTap-IPV B group. Non-inferiority of dTap-IPV B to dTap-IPV R was demonstrated. Both vaccines had a clinically acceptable safety and reactogenicity profile when co-administered with MMRV to children 3-4 years old.

    2017-07-01

    As endemic measles is eliminated through immunization, countries must determine the risk factors for the importation of measles into highly immunized populations to target control measures. Despite eliminating endemic measles, New Zealand suffers from outbreaks after introductions from abroad, enabling us to use it as a model for measles introduction risk. We used a generalized linear model to analyze risk factors for 1137 measles cases from 2007 to June 2014, provide estimates of national immunity levels, and model measles importation risk. People of European ethnicity made up the majority of measles cases. Age is a positive risk factor, particularly 0-2-year-olds and 5-17-year-old Europeans, along with increased wealth. Pacific islanders were also at greater risk, but due to 0-2-year-old cases. Despite recent high measles, mumps, and rubella vaccine immunization coverage, overall population immunity against measles remains ~90% and is lower in people born between 1982 and 2005. Greatest measles importation risk is during December, and countries predicted to be sources have historical connections and highest travel rates (Australia and UK), followed by Asian countries with high travel rates and higher measles incidences. Our results suggest measles importation due to travel is seeding measles outbreaks, and immunization levels are insufficient to continue to prevent outbreaks because of heterogeneous immunity in the population, leaving particular age groups at risk.

    An outbreak of mumps within a student population in Scotland was investigated to assess the effect of previous vaccination on infection and clinical presentation, and any genotypic variation. Of the 341 cases, 79% were aged 18-24. Vaccination status was available for 278 cases of whom 84% had received at least one dose of mumps containing vaccine and 62% had received two. The complication rate was 5·3% (mainly orchitis), and 1·2% were admitted to hospital. Genetic sequencing of mumps virus isolated from cases across Scotland classified 97% of the samples as genotype G. Two distinct clusters of genotype G were identified, one circulating before the outbreak and the other thereafter, suggesting the virus that caused this outbreak was genetically different from the previously circulating virus. Whilst the poor vaccine effectiveness we found may be due to waning immunity over time, a contributing factor may be that the current mumps vaccine is less effective against some genotypes. Although the general benefits of the measles-mumps-rubella (MMR) vaccine should continue to be promoted, there may be value in reassessing the UK vaccination schedule and the current mumps component of the MMR vaccine.

    Lund, G.A.; Salmi, A.A.

    1982-01-01

    Guinea pig and rabbit antisera from animals immunized with purified measles virus hemagglutinin (G) protein were used to establish a solid-phase four-layer radioimmunoassay for quantitative measurement of the G protein. The sensitivity of the assay was 2 ng of purified G protein, and 200 μg of protein from uninfected Vero cells neither decreased the sensitivity nor reacted non-specifically in the assay. Radioimmunoassay standard dose-response curves were established and unknown values interpolated from these using the logit program of a desktop computer. Using this procedure, a measles virus growth curve in infected Vero cells was determined by measurement of G protein production. Under these same conditions, hemagglutination was not sensitive enough to detect early hemagglutinin production. Viral antigens in canine distemper virus, Newcastle disease virus, parainfluenza viruses 1-4, simian virus 5, and respiratory syncytial virus-infected cell lysates did not cross-react in the radioimmunoassay. A small degree of cross-reactivity was detected with mumps viral antigens, both with Vero cell-derived (wild-type strain) and egg-derived (Enders strain) purified virus preparations and with a cell lysate antigen prepared from wild-type mumps virus-infected Vero cells.

    This investigation was done to assess vaccine effectiveness of one and two doses of the measles, mumps and rubella (MMR) vaccine during an outbreak of mumps in Ontario. The level of coverage required to reach herd immunity and interrupt community transmission of mumps was also estimated. Information on confirmed cases of mumps was retrieved from Ontario's integrated Public Health Information System. Cases that occurred between Sept. 1, 2009, and June 10, 2010, were included. Selected health units supplied coverage data from the Ontario Immunization Record Information System. Vaccine effectiveness by dose was calculated using the screening method. The basic reproductive number (R(0)) represents the average number of new infections per case in a fully susceptible population, and R(0) values of between 4 and 10 were considered for varying levels of vaccine effectiveness. A total of 134 confirmed cases of mumps were identified. Information on receipt of MMR vaccine was available for 114 (85.1%) cases, of whom 63 (55.3%) reported having received only one dose of vaccine; 32 (28.1%) reported having received two doses. Vaccine effectiveness of one dose of the MMR vaccine ranged from 49.2% to 81.6%, whereas vaccine effectiveness of two doses ranged from 66.3% to 88.0%. If we assume vaccine effectiveness of 85% for two doses of the vaccine, vaccine coverage of 88.2% and 98.0% would be needed to interrupt community transmission of mumps if the corresponding reproductive values were four and six. Our estimates of vaccine effectiveness of one and two doses of mumps-containing vaccine were consistent with the estimates that have been reported in other outbreaks. Outbreaks occurring in Ontario and elsewhere serve as a warning against complacency over vaccination programs.

    The most common preventative measure against mumps is vaccination with mumps vaccine. In most parts of the world, mumps vaccine is routinely delivered through live attenuated Measles-Mumps-Rubella (MMR) vaccine. In Japan, receiving mumps vaccine is voluntary and vaccine uptake rate is less than 30%. The introduction of mumps vaccine into routine vaccination schedule has become one of the current topics in health policy and has raised the need to evaluate efficient ways in protecting children from mumps-related diseases in Japan. We conducted a cost-effectiveness analysis with Markov model and calculated incremental cost effectiveness ratios (ICERs) of 11 different programmes; a single-dose programme at 12-16 months and 10 two-dose programmes with second dose uptakes at ages 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11. Our base-case analyse set the cost per shot at ¥6951 (US$72; 1US$=96.8). Results show that single-dose programme dominates status quo. On the other hand, ICERs of all 10 two-dose programmes are under ¥6,300,000 (US$65,082) per QALY from payer's perspective while it ranged from cost-saving to <¥7,000,000 (US$72,314) per QALY from societal perspective. By adopting WHO's classification that an intervention is cost-effective if ICER (in QALY) is between one and three times of GDP as a criterion, either of the vaccination programme is concluded as cost-effective from payer's or societal perspectives. Likewise, to uptake second dose at 3-5 years old is more favourable than an uptake at any other age because of lower incremental cost-effectiveness ratios. Copyright © 2014 Elsevier Ltd.

  15. Sounding rocket flight report: MUMP 9 and MUMP 10

    Grassl, H. J.

    1971-01-01

    The results of the launching of two Marshall-University of Michigan Probes (MUMP 9 and MUMP 10), Nike-Tomahawk sounding rocket payloads, are summarized. The MUMP 9 paylaod included an omegatron mass analyzer, a molecular fluorescence densitometer, a mini-tilty filter, and a lunar position sensor. This complement of instruments permitted the determination of the molecular nitrogen density and temperature in the altitude range from approximately 143 to 297 km over Wallops Island, Virginia, during January 1971. The MUMP 10 payload included an omegatron mass analyzer, an electron temperature probe (Spencer, Brace, and Carignan, 1962), a cryogenic densitometer, and a solar position sensor. This complement of instruments permitted the determination of the molecular nitrogen density and temperature and the charged particle density and temperature in the altitude range from approximately 145 to 290 km over Wallops Island, Virginia, during the afternoon preceding the MUMP 9 launch in January 1971. A general description of the payload kinematics, orientation analysis, and the technique for the reduction and analysis of the data is given.

    China has used 3 different mumps-containing vaccines (MuCV) since 1990: monovalent mumps vaccine, measles-mumps (MM) vaccine, and measles-mumps-rubella (MMR) vaccine, and one dose MuCV (using MMR at 18 months) has been included in the EPI since 2007. MuCV effectiveness has been of concern following large-scale mumps outbreaks. In 2015, an outbreak of mumps occurred in a primary school, which allow us assess vaccine effectiveness of different MuCVs. All children in the school were studied as a retrospective cohort. Vaccination histories and case information were obtained from vaccination records and clinic/hospital logs. Parental questionnaires were used to confirm students' illnesses and calculate attack rate (AR). VE was assessed using the formula, VE = (AR in unvaccinated students- AR in the vaccinated students) / (AR in unvaccinated students). VEs of different type of MuCV were compared. In total, 283 students were identified as clinical mumps among the 2370 students, and 1908 students were included for MuCV VE assessment. 213 (including 21 [8.9%] patients) were 2-dose MuCV recipients (AR: 9.9%), 1165 (including 123 [51.9%] patients) were 1-dose recipients (AR: 10.6%), and 530 (including 93 [39.2%] patients) were unvaccinated (AR: 17.5%). VE was 44% for 2 doses and 40% for one dose. For one-MuCV-dose students, estimated mumps VE was 63% for vaccinated within 3 years (between vaccination and this outbreak); 50% for vaccinated within 3 to 5 years; and 34% for vaccinated more than 5 years. Comparing VE by vaccine type and 5-year interval since vaccination, VE for MMR was 60%, which was consistently higher than VE for monovalent mumps vaccine (22%) and MM (2%). This outbreak was associated with low and declining 1-dose MuCV effectiveness. China's immunization program should evaluate the potential of a 2-dose MMR schedule to adequately control mumps.

    Mumps virus infection primarily affects the salivary glands and may incur various complications. Laryngeal edema is such a rare complication that few adult cases have been reported. We report the first known pediatric patient with mumps with laryngeal edema. An 8-year-old boy developed dyspnea after a rapidly progressive swelling of his face and neck. Laryngoscopy revealed edematous changes in the supraglottic and subglottic regions, and computed tomography confirmed significant laryngeal edema in addition to swelling of the cervical soft tissue and the salivary glands. Laboratory findings revealed a high serum amylase level and confirmed the diagnosis of mumps. Intravenous steroid administration alleviated the dyspnea, although the patient required temporary tracheal intubation to maintain airway patency. He did not need tracheotomy and did not experience any other complications. Laryngeal edema must be regarded as a rare, potentially life-threatening complication of mumps. When mumps is diagnosed with significant swelling of the neck, an emergency airway should be established to prevent airway obstruction.

  18. Mumps epidemiology in the mid-west of Ireland 2004-2008: increasing disease burden in the university/college setting.

    Whyte, D

    2009-01-01

    Mumps is a contagious vaccine-preventable viral disease that is experiencing a revival in students attending second and third level colleges. Large mumps outbreaks have been reported in several countries despite the presence of childhood immunisation programmes over many years, including measles, mumps, and rubella (MMR) vaccination. In 2008, 1,377 cases of mumps were notified in Ireland and 1,734 in the first three months of 2009 (provisional data). This paper reviews the recent epidemiology of mumps in the Mid-West region of Ireland and highlights preventive measures. A substantial proportion of cases were not laboratory-confirmed and it is important that doctors continue to notify suspected cases. In the Irish Mid-West, data from enhanced surveillance shows a high proportion of mumps in the age group 15-24 years. Complications were uncommon and rarely severe. Where data were available, over half of the cases did not recall having received two doses of MMR, but most recalled one dose. Parents should continue to ensure children receive both MMR vaccinations so that uptake is optimal for protection. Steps were taken to increase awareness of the disease in the school, college and university settings. Preventive measures implemented to limit mumps transmission in the school\\/college setting over recent years included vaccination of close contacts, isolation for five days and hand hygiene.

    To evaluate the performance of a newly developed point-of-care test (POCT) for the detection of measles-specific IgM antibodies in serum and oral fluid specimens and to assess if measles virus nucleic acid could be recovered from used POCT strips. The POCT was used to test 170 serum specimens collected through measles surveillance or vaccination programmes in Ethiopia, Malaysia and the Russian Federation: 69 were positive for measles immunoglobulin M (IgM) antibodies, 74 were positive for rubella IgM antibodies and 7 were positive for both. Also tested were 282 oral fluid specimens from the measles, mumps and rubella (MMR) surveillance programme of the United Kingdom of Great Britain and Northern Ireland. The Microimmune measles IgM capture enzyme immunoassay was the gold standard for comparison. A panel of 24 oral fluids was used to investigate if measles virus haemagglutinin (H) and nucleocapsid (N) genes could be amplified by polymerase chain reaction directly from used POCT strips. With serum POCT showed a sensitivity and specificity of 90.8% (69/76) and 93.6% (88/94), respectively; with oral fluids, sensitivity and specificity were 90.0% (63/70) and 96.2% (200/208), respectively. Both H and N genes were reliably detected in POCT strips and the N genes could be sequenced for genotyping. Measles virus genes could be recovered from POCT strips after storage for 5 weeks at 20-25 °C. The POCT has the sensitivity and specificity required of a field-based test for measles diagnosis. However, its role in global measles control programmes requires further evaluation.

    Previous studies have suggested that girls may have lower maternal measles antibody levels than boys. Girls might therefore be more likely to contract measles infection before the normal age of measles vaccination at 9 months of age. In connection with a clinical trial of different measles vaccination strategies, we collected pre-measles vaccination blood samples at 4.5 months of age from two subgroups of children. Samples from these children were used to assess possible differences in maternal antibody levels for boys and girls. At 9 months of age another subgroup of children was sampled before the normal measles vaccination; these samples were used to assess the frequency of subclinical measles infection among boys and girls. We determined measles-specific antibody levels for 812 children at 4.5 months of age and for 896 children at 9 months of age. At 4.5 months of age girls were less likely to have protective maternal antibody levels, the male-female ratio for protective antibody level being 1.23 (1.00-1.51). Among children sampled at 9 months of age, girls were more likely to have protective levels, the female-male ratio for having protective antibody levels being 1.65 (0.98-2.78) (p=0.054) and the geometric mean titre was significantly higher for girls (p=0.007). Children who lived in houses with known measles cases were more likely to have protective levels at 9 months of age even though they had not reported measles infection. Since we had excluded children with known measles infection, girls may have been more likely to have had subclinical measles infection. Combining clinical and possible subclinical measles infection, girls tended to be more likely than boys to contract measles infection before 9 months of age, the RR being 1.36 (0.97-1.90). Girls lost maternal measles antibodies more rapidly than boys and well before 9 months of age. They may be more likely to contract subclinical measles infection before the current age of measles vaccination.

  2. SAFETY AND IMMUNOLOGIC EFFICACY OF COMBINED IMMUNIZATION IN CHILDREN AGED 6—7 YEARS WITH VACCINES FROM THE NATIONAL CALENDAR OF PROPHYLACTICS VACCINES

    I. V. Konovalov

    2013-01-01

    Full Text Available We estimated the safety of the vaccination for prevention of influenza with Grippol® plus vaccine alongside with vaccination with combined preparations for the prevention of diphtheria and tetanus (Td and measles, rubella, mumps in children aged 6—7 years. We determined that combined immunization with the indicated vaccines proves good tolerability and low reactogenicity. Vaccine Grippol® Plus shows low reactogenicity , high immunologenicity and does not cause cross-suppression of antibodies in co-administration with other vaccines on vaccination calendar. Also concomitant vaccination with Grippol® plus and other vaccines does not inhibit the development of a specific immune response against influenza.

  3. Combination of the oral histone deacetylase inhibitor resminostat with oncolytic measles vaccine virus as a new option for epi-virotherapeutic treatment of hepatocellular carcinoma

    Benjamin Ruf

    Full Text Available Epigenetic therapies such as histone deacetylase inhibitors (HDACi not only have the capability to decrease tumor cell proliferation and to induce tumor cell death but also to silence antiviral response genes. Here, we investigated whether the combination of an oncolytic measles vaccine virus (MeV with the novel oral HDACi resminostat (Res, being in clinical testing in patients with hepatocellular carcinoma (HCC, results in an enhanced efficacy of this epi-virotherapeutic approach compared to any of the two corresponding monotherapies. When testing a panel of human hepatoma cell lines, we found (i a significantly improved rate of primary infections when using oncolytic MeV under concurrent treatment with resminostat, (ii a boosted cytotoxic effect of the epi-virotherapeutic combination (Res + MeV with enhanced induction of apoptosis, and, quite importantly, (iii an absence of any resminostat-induced impairment of MeV replication and spread. Beyond that, we could also show that (iv resminostat, after hepatoma cell stimulation with exogenous human interferon (IFN-β, is able to prevent the induction of IFN-stimulated genes, such as IFIT-1. This finding outlines the possible impact of resminostat on cellular innate immunity, being instrumental in overcoming resistances to MeV-mediated viral oncolysis. Thus, our results support the onset of epi-virotherapeutic clinical trials in patients exhibiting advanced stages of HCC.

    2013-05-31

    In this study, we modeled the cost benefit analysis for three different measles vaccination strategies based upon three different measles-containing vaccines in Korea, 2001. We employed an economic analysis model using vaccination coverage data and population-based measles surveillance data, along with available estimates of the costs for the different strategies. In addition, we have included analysis on benefit of reduction of complication by mumps and rubella. We evaluated four different strategies: strategy 1, keep-up program with a second dose measles-mumps-rubella (MMR) vaccine at 4-6 years without catch-up campaign; strategy 2, additional catch-up campaign with measles (M) vaccine; strategy 3, catch-up campaign with measles-rubella (MR) vaccine; and strategy 4, catch-up campaign with MMR vaccine. The cost of vaccination included cost for vaccines, vaccination practices and other administrative expenses. The direct benefit of estimated using data from National Health Insurance Company, a government-operated system that reimburses all medical costs spent on designated illness in Korea. With the routine one-dose MMR vaccination program, we estimated a baseline of 178,560 measles cases over the 20 years; when the catch-up campaign with M, MR or MMR vaccines was conducted, we estimated the measles cases would decrease to 5936 cases. Among all strategies, the two-dose MMR keep-up program with MR catch-up campaign showed the highest benefit-cost ratio of 1.27 with a net benefit of 51.6 billion KRW. Across different vaccination strategies, our finding suggest that MR catch-up campaign in conjunction with two-dose MMR keep-up program was the most appropriate option in terms of economic costs and public health effects associated with measles elimination strategy in Korea.

  6. Will Synergizing Vaccination with Therapeutics Boost Measles Virus Eradication?

    Plemper, Richard K; Hammond, Anthea L

    2014-01-01

    Introduction Measles virus is a major human pathogen responsible for approximately 150,000 measles deaths annually. The disease is vaccine preventable and eradication of the virus is considered feasible in principle. However, a herd immunity exceeding 95% is required to prevent sporadic viral outbreaks in a population. Declining disease prevalence combined with public anxieties about vaccination safety has increased vaccine refusal especially in the European region, which has resulted in measles resurgence in some areas. Areas covered Here, we discuss whether synergizing effective measles therapeutics with vaccination could contribute to solving an endgame conundrum of measles elimination by accelerating the eradication effort. Based on an anticipated use for protection of high-risk contacts of confirmed measles cases through post-exposure prophylaxis, we identify key elements of the desirable drug profile, review current disease management strategies and the state of experimental inhibitor candidates, evaluate the risk associated with viral escape from inhibition, and consider the potential of measles therapeutics for the management of persistent viral infection of the CNS. Assuming a post-measles world with waning measles immunity, we contemplate the possible impact of therapeutics on controlling the threat imposed by closely related zoonotic pathogens of the same genus as measles virus. Expert opinion Efficacious therapeutics given for post-exposure prophylaxis of high-risk social contacts of confirmed index cases may aid measles eradication by closing herd immunity gaps due to vaccine refusal or failure in populations with overall good vaccination coverage. The envisioned primarily prophylactic application of measles therapeutics to a predominantly pediatric and/or adolescent patient population dictates the drug profile; the article must be safe and efficacious, orally available, shelf-stable at ambient temperature, and amenable to cost-effective manufacture

  7. Notes from the Field: Measles Transmission in an International Airport at a Domestic Terminal Gate--April-May 2014.

    Banerjee, Emily; Hickman, Cynthia; Engels, Kathryn; Kenyon, Cynthia

    2015-06-26

    On April 22, 2014, the Minnesota Department of Health notified CDC of a case of measles in a child aged 19 months who had documentation of receiving 1 dose of measles, mumps, and rubella vaccine at age 12 months. The child's illness was clinically compatible with measles, which was confirmed by polymerase chain reaction and immunoglobulin M serology at the Minnesota Department of Health Public Health Laboratory. The child was febrile and developed a rash on April 17 while on an international flight from India to the United States before taking a connecting flight from Chicago to Minneapolis. Persons with measles are infectious from 4 days before to 4 days after rash onset. Therefore, travelers were exposed on both the international and domestic flights. CDC's Division of Global Migration and Quarantine was contacted and provided information on potentially exposed persons to relevant health departments for follow-up. No documented transmission was reported as a result of the two flight exposures.

    2016-01-01

    Full Text Available Introduction: Mumps is an acute infectious disease caused by mumps virus. The main pathologic feature is serofibrinous inflammation of the salivary glands, resulting in their swelling. In pre-puberty children the course of illness is usually benign, and approximately one third of the cases remain subclinical. Extrasalivary gland involvement, such as orchitis, meningitis, pancreatitis is possible. The inflammation of pancreas takes an auspicious course and lasting sequels, such as diabetes mellitus or pancreatic cancer, do not occur. Orchitis occurs in 15-40% of postpubertal males with mumps, and without treatment 30-50% of them develop testicular atrophy, which is associated with male infertility. The testicular atrophy after recovery from mumps orchitis is linked as a predisposing factor for testicular cancer. Objective: To present a case report of patient with multi-organ localization of mumps virus and to analyze the severity of the specific organ form of the disease. Case report: We present a case report of mumps, in combination with mumps orchitis and mumps pancreatitis in 25 years old man, hospitalized in the Clinic of infectious diseases - Varna. Diagnosis was established on the basis of clinical features of disease, epidemiological, biochemical and serological data, realized through the relevant laboratories in the St. Marina Hospital - Varna. Results: In the presented case, the disease started as a moderate form of mumps affecting both parotid glands, and 3 days after the onset of the symptoms, pancreatitis and orchitis occurred. Conclusion: multi-organ involvement in the clinical course of mumps, taking its with is usual manifestation of the disease. In spite of the multiple organ involvement in this case, the patient recovered without lasting sequels.

  10. Controlling measles using supplemental immunization activities: a mathematical model to inform optimal policy.

    Verguet, Stéphane; Johri, Mira; Morris, Shaun K; Gauvreau, Cindy L; Jha, Prabhat; Jit, Mark

    2015-03-03

    The Measles & Rubella Initiative, a broad consortium of global health agencies, has provided support to measles-burdened countries, focusing on sustaining high coverage of routine immunization of children and supplementing it with a second dose opportunity for measles vaccine through supplemental immunization activities (SIAs). We estimate optimal scheduling of SIAs in countries with the highest measles burden. We develop an age-stratified dynamic compartmental model of measles transmission. We explore the frequency of SIAs in order to achieve measles control in selected countries and two Indian states with high measles burden. Specifically, we compute the maximum allowable time period between two consecutive SIAs to achieve measles control. Our analysis indicates that a single SIA will not control measles transmission in any of the countries with high measles burden. However, regular SIAs at high coverage levels are a viable strategy to prevent measles outbreaks. The periodicity of SIAs differs between countries and even within a single country, and is determined by population demographics and existing routine immunization coverage. Our analysis can guide country policymakers deciding on the optimal scheduling of SIA campaigns and the best combination of routine and SIA vaccination to control measles.

    Mumps outbreaks continue to occur, even after the consolidation of vaccination programs. An outbreak of mumps occurred in a high school in Zaragoza during December 2011. To describe the outbreak and estimate vaccine effectiveness. unilateral or bilateral swelling of the parotid or other salivary glands for three or more days without any other apparent cause. People attending the 'Parque Goya' High School or with transmission chain origin in the High School. From two days before the onset of symptoms of the first case to five days after the last case. Samples were collected for virus confirmation (IgM, urine culture and oropharyngeal exudate), and isolates were processed for genotyping. A retrospective cohort study was performed in two high school classrooms to estimate vaccine efficacy. Public health authorities conducted active surveillance, isolation of cases, and vaccination of susceptible contacts. There were 27 cases. Twenty-one (77.8%) were vaccinated with two doses of Measles-Mumps-Rubella vaccine. Twelve (44%) were confirmed microbiologically. G1 genotype was determined in six cases. According to the cohort study, vaccine efficacy for one dose was 34% (95%CI: -44 to 70), and was 67% (95%CI: 28 to 83) for two doses. Vaccine effectiveness was lower than expected. Early detection and isolation of cases have been instrumental in preventing new cases in schools.

  12. Mumps outbreak in Incheon, Korea, 2009

    Seon Young Cho

    2010-01-01

    Full Text Available Purpose : Recently, we have noticed an increase in the number of patients with mumps in Incheon, Korea. The aim of this study is to estimate the regional trend in mumps incidence and to evaluate the factors related to the recent increase. Methods : We reviewed the medical records of 66 patients with mumps who had been admitted to Incheon St. Mary’s Hospital from July 1999 to June 2009. We compared the differences in records between “outbreak, 2009” and “nonoutbreak, 2000&#8211;2008.” Results : Of the 66 patients, 35 (53% were admitted in 2009, and 31 (47% were admitted between 2000 and 2008. Most of the patients admitted during the outbreak were over 15 years of age (80.0%, were born before 1993 (77.1%, and had received a single dose of mumps vaccine (62.9%. There were no significant differences in contact history, present address, clinical manifestations, and complications, except for orchitis, between the two groups. Conclusion : There was a sharp increase in the number of inpatients with mumps who were born before 1993 and who were over 15 years of age. We recommend that a booster vaccination be considered for adolescents and young adults born before 1993 who are susceptible to mumps infection due to their reduced opportunities for receiving two doses of mumps vaccine.

    The introduction of the inactivated poliovirus vaccine (IPV) represents a crucial step in the polio eradication endgame. This trial examined the safety and immunogenicity of IPV given alongside the measles-rubella and yellow fever vaccines at 9 months and when given as a full or fractional dose using needle and syringe or disposable-syringe jet injector. We did a phase 4, randomised, non-inferiority trial at three periurban government clinics in west Gambia. Infants aged 9-10 months who had already received oral poliovirus vaccine were randomly assigned to receive the IPV, measles-rubella, and yellow fever vaccines, singularly or in combination. Separately, IPV was given as a full intramuscular or fractional intradermal dose by needle and syringe or disposable-syringe jet injector at a second visit. The primary outcomes were seroprevalence rates for poliovirus 4-6 weeks post-vaccination and the rate of seroconversion between baseline and post-vaccination serum samples for measles, rubella, and yellow fever; and the post-vaccination antibody titres generated against each component of the vaccines. We did a per-protocol analysis with a non-inferiority margin of 10% for poliovirus seroprevalence and measles, rubella, and yellow fever seroconversion, and (1/3) log2 for log2-transformed antibody titres. This trial is registered with ClinicalTrials.gov, number NCT01847872. Between July 10, 2013, and May 8, 2014, we assessed 1662 infants for eligibility, of whom 1504 were enrolled into one of seven groups for vaccine interference and one of four groups for fractional dosing and alternative route of administration. The rubella and yellow fever antibody titres were reduced by co-administration but the seroconversion rates achieved non-inferiority in both cases (rubella, -4·5% [95% CI -9·5 to -0·1]; yellow fever, 1·2% [-2·9 to 5·5]). Measles and poliovirus responses were unaffected (measles, 6·8% [95% CI -1·4 to 14·9]; poliovirus serotype 1, 1·6% [-6·7 to 4·7

  15. Can mumps vaccine induce remission in recurrent respiratory papilloma?

    Pashley, Nigel R T

    2002-07-01

    To describe our experience using laser excision and locally injected mumps vaccine to induce remission in patients with recurrent respiratory papilloma (RRP). Tertiary care regional medical center. Initially, 11 children with RRP treated in a pilot study with laser excision at regular intervals for at least a year without adjuvant therapy; later, a series of 18 children and 20 adults with RRP, some of whom had used various adjuvant therapy with interval laser excision. Both patient groups continued their same interval laser excision with the same or similar laser, same clinical setting, and same surgeon. Locally injected mumps vaccine was then administered into the excision site after each laser removal of papilloma. Larynx and trachea were microphotographed with each treatment. Two consecutive disease-free intervals and a follow-up of at least 1 year were required criteria for remission. In the pilot study, remission was induced in 9 (82%) of 11 patients by 1 to 10 injections, with follow-up of 5 to 19 years. In the subsequent series, remission was induced in 29 (76%) of 38 patients by 4 to 26 injections, and follow-up was 2 to 5 years. Combined with serial laser excision, mumps vaccine positively influences induction of remission in children with RRP. The mechanisms of this effect are unclear, but the treatment is readily available, inexpensive, and has a low risk of adverse effects.

    Jané, Mireia; Torner, Nuria; Vidal, Ma José

    2015-01-01

    Measles and rubella are two immuno-preventive illnesses. In Catalonia, since 1988 all children are given two doses of measles and rubella vaccine with high levels of vaccination coverage. The measles elimination programme has been carried out since 1990 in Catalonia. This programme includes achieving and keeping high immunization levels among population with high vaccination coverage, intense epidemiological surveillance and an immediate response to the appearance of a case or outbreak. In 2014, the measles incidence rate was 1.9 cases/ 100,000 inhabitants. There were 4 recent outbreaks in 2006, 2011, 2013 and 2014 that affected 381, 289, 31 and 124 people respectively. All outbreaks were triggered by an imported case. In 2011 and 2014 measles outbreaks, 6% and 5.5% of affected people were health care workers. All outbreaks presented a great variety of measles genotypes. Concerning rubella elimination programme, since 2002, 68 cases of postnatal rubella and 5 cases of congenital rubella were confirmed. Regarding measles and rubella surveillance and control, in addition to strengthen vaccination coverage, it is essential immediate notification, within the first 24 hours since suspicion and laboratory confirmation. In addition there is a need to enforce vaccination among health care workers as well as in other susceptible and unvaccinated people. It is recommended to vaccinate all people who were born after 1966 and who have not been vaccinated with two doses of trivalent measles-mumps-rubella vaccine. Furthermore, we have to emphasize that the progress concerning genotypes study allows identifying various imported cases from other European countries with active outbreaks, aspect that makes easier the surveillance of these illnesses.

  1. Comparison of the effectiveness of two mumps vaccines during an outbreak in Switzerland in 1999 and 2000: A case-cohort study

    Richard, Jean-Luc; Zwahlen, Marcel; Feuz, Mirjam; Matter, Hans C.

    2003-01-01

    In two recent nation-wide outbreaks of mumps in Switzerland two-thirds of young children with clinical mumps had a history of primary vaccination. On average, measles-mumps-rubella (MMR) vaccination coverage is 80%. Two types of vaccine are commonly used: Jeryl-Lynn and Rubini. The effectiveness of the latter has been questioned in several publications. The authors therefore compared Rubini to Jeryl-Lynn in a case-cohort study. The study included 111 young children with clinical mumps who had been reported to the Swiss Federal Office of Public Health (SFOPH) by primary care physicians of the Swiss Sentinel Surveillance Network (SSSN) between January 1999 and May 2000. Sentinel physicians also sampled 661 children from the same birth cohort as the cases. While we found no evidence for the effectiveness of the Rubini strain, vaccination with the Jeryl-Lynn strain was 70% effective against clinical mumps. Furthermore, children vaccinated with the Rubini strain attended primary health care more frequently with clinical mumps than those who had received Jeryl-Lynn (odds ratio: 2.4; 95% confidence interval (CI): 1.3, 4.7). Restricting the analysis to laboratory confirmed cases increased the odds ratio to 18.4 (95% CI: 2.5, 811.2). Our study confirms the low effectiveness of the Rubini strain vaccine in the field. This vaccine should therefore be considered inappropriate for the control and elimination of mumps and its use should be discontinued. As other vaccines with comparable quality and safety standards and a substantially higher effectiveness are available the MMR vaccination program in Switzerland will not be compromised if the use of Rubini is no longer recommended

  3. Measles Vaccination in the Presence or Absence of Maternal Measles Antibody: Impact on Child Survival

    Aaby, Peter; Martins, Cesário L.; Garly, May-Lill; Andersen, Andreas; Fisker, Ane B.; Claesson, Mogens H.; Ravn, Henrik; Rodrigues, Amabelia; Whittle, Hilton C.; Benn, Christine S.

    2014-01-01

    Background. Measles vaccine (MV) has a greater effect on child survival when administered in early infancy, when maternal antibody may still be present. Methods. To test whether MV has a greater effect on overall survival if given in the presence of maternal measles antibody, we reanalyzed data from 2 previously published randomized trials of a 2-dose schedule with MV given at 4–6 months and at 9 months of age. In both trials antibody levels had been measured before early measles vaccination. Results. In trial I (1993–1995), the mortality rate was 0.0 per 1000 person-years among children vaccinated with MV in the presence of maternal antibody and 32.3 per 1000 person-years without maternal antibody (mortality rate ratio [MRR], 0.0; 95% confidence interval [CI], 0–.52). In trial II (2003–2007), the mortality rate was 4.2 per 1000 person-years among children vaccinated in presence of maternal measles antibody and 14.5 per 1000 person-years without measles antibody (MRR, 0.29; 95% CI, .09–.91). Possible confounding factors did not explain the difference. In a combined analysis, children who had measles antibody detected when they received their first dose of MV at 4–6 months of age had lower mortality than children with no maternal antibody, the MRR being 0.22 (95% CI, .07–.64) between 4–6 months and 5 years. Conclusions. Child mortality in low-income countries may be reduced by vaccinating against measles in the presence of maternal antibody, using a 2-dose schedule with the first dose at 4–6 months (earlier than currently recommended) and a booster dose at 9–12 months of age. Clinical Trials Registration. NCT00168558. PMID:24829213

    2014-12-11

    This paper describes the epidemiology and management of a prolonged outbreak of measles across the 2.7 million conurbation of Greater Manchester in the United Kingdom. Over a period of one year (from October 2012 to September 2013), over a thousand suspected measles cases (n = 1,073) were notified across Greater Manchester; of these, 395 (37%) were laboratory-confirmed, 91 (8%) were classed as probable, 312 (29%) were classed as possible and 275 (26%) excluded. Most confirmed and probable cases occurred in children within two age groups—infants (too young to be eligible for measles-mumps-rubella (MMR) vaccination according to the national immunisation programme) and children aged 10-19 years (low vaccine uptake in this cohort because of unfounded alleged links between the MMR vaccine and autism). During this one year period, there were a series of local outbreaks and many of these occurred within the secondary school setting. A series of public health measures were taken to control this prolonged outbreak: setting up incident management teams to control local outbreaks, a concerted immunisation catch-up campaign (initially local then national) to reduce the pool of children partially or totally unprotected against measles, and the exclusion of close contacts from nurseries and school settings for a period of 10 days following the last exposure to a case of measles.

  6. Biological Feasibility of Measles Eradication

    Strebel, Peter

    2011-01-01

    Recent progress in reducing global measles mortality has renewed interest in measles eradication. Three biological criteria are deemed important for disease eradication: (1) humans are the sole pathogen reservoir; (2) accurate diagnostic tests exist; and (3) an effective, practical intervention is available at reasonable cost. Interruption of transmission in large geographical areas for prolonged periods further supports the feasibility of eradication. Measles is thought by many experts to meet these criteria: no nonhuman reservoir is known to exist, accurate diagnostic tests are available, and attenuated measles vaccines are effective and immunogenic. Measles has been eliminated in large geographical areas, including the Americas. Measles eradication is biologically feasible. The challenges for measles eradication will be logistical, political, and financial. PMID:21666201

To assess the mumps vaccine effectiveness (VE) in Guangzhou, China, we performed a 1:1 matched case-control study. Among children in Guangzhou aged 8 mo to 12 y during 2006 to 2012, we matched one healthy child to each child with clinically diagnosed mumps. Cases with clinically diagnosed mumps were identified from surveillance sites system and healthy controls were randomly sampled from the Children's Expanded Programmed Immunization Administrative Computerized System in Guangzhou. Conditional logistic regression was used to calculate VE. We analyzed the vaccination information for 1983 mumps case subjects and 1983 matched controls and found that the overall VE for 1 dose of mumps vaccine, irrespective of the manufacture, was 53.6% (95% confidence interval [CI], 41.0-63.5%) to children aged 8 mo to 12 y. This post-marketing mumps VE study found that immunization with one dose of the mumps vaccine confers partial protection against mumps disease. Evaluation of the VE for the current mumps vaccines, introduction of a second dose of mumps vaccine, and assessment of modifications to childhood immunization schedules is essential.

    2013-01-01

    Measles cases in the European Region have been increasing in the last decade; this illustrates the challenge of what we are now encountering in the form of pediatric preventable diseases. In Catalonia, autochthonous measles was declared eliminated in the year 2000 as the result of high measles-mumps-rubella vaccine (MMR) coverage for first and second dose (15 mo and 4 y) since the mid-1990s. From then on, sporadic imported cases and small outbreaks appeared, until in 2006–2007 a large measles outbreak affecting mostly unvaccinated toddlers hit the Barcelona Health Region. Consequently, in January 2008, first dose administration of MMR was lowered from 15 to 12 mo of age. A new honeymoon period went by until the end of 2010, when several importations of cases triggered new sustained transmission of different wild measles virus genotypes, but this time striking young adults. The aim of this study is to show the effect of a change in MMR vaccination schedule policy, and the difference in age incidence and hospitalization rates of affected individuals between both outbreaks. Epidemiologic data were obtained by case interviews and review of medical records. Samples for virological confirmation and genotyping of cases were collected as established in the Measles Elimination plan guidelines. Incidence rate (IR), rate ratio (RR) and their 95% CI and hospitalization rate (HR) by age group were determined. Statistic z was used for comparing proportions. Total number of confirmed cases was 305 in the 2010 outbreak and 381 in the 2006–2007 outbreak; mean age 20 y (SD 14.8 y; 3 mo to 51 y) vs. 15 mo (SD 13.1 y; 1 mo to 50 y). Highest proportion of cases was set in ≥ 25 y (47%) vs. 24.2% in 2006 (p < 0.001). Differences in IR for ≤ 15 mo (49/100,000 vs. 278.2/100,000; RR: 3,9; 95%CI 2,9–5.4) and in overall HR 29.8% vs. 15.7% were all statistically significant (p < 0.001). The change of the month of age for the administration of the first MMR dose proved successful to

  13. Case of mumps orchitis after vaccination.

    Kanda, Takayoshi; Mochida, Junichi; Takada, Shogo; Hori, Yutaro; Yamaguchi, Kenya; Takahashi, Satoru

    2014-04-01

    We present a case of mumps orchitis after vaccination. A 35-year-old man visited the emergency unit of our hospital for fever and right testicular pain on 7 January 2012. Two weeks before the visit, he underwent vaccination for mumps. After 7 days of hospitalization, the patient recovered from fever and testicular pain. Scrotal magnetic resonance imaging suggested right orchitis, and an increased level of serum mumps immunoglobulin M and immunoglobulin G indicated an initial infection of mumps virus. The peak value of immunoglobulin G showed 106 enzyme immunoassay unit 5 weeks after vaccination, which was 10-fold higher than the ordinary rise of a vaccinated individual. This fact leads to two possibilities. One is this happened as an adverse event of vaccination, and the other is that he actually had a wild-type infection at the same time as vaccination. There are some reports regarding adverse events of mumps vaccine; however, they might include wild-type infection. © 2013 The Japanese Urological Association.

  14. Application of Oral Fluid Assays in Support of Mumps, Rubella and Varicella Control Programs

    Peter A. C. Maple

    2015-12-01

    Full Text Available Detection of specific viral antibody or nucleic acid produced by infection or immunization, using oral fluid samples, offers increased potential for wider population uptake compared to blood sampling. This methodology is well established for the control of HIV and measles infections, but can also be applied to the control of other vaccine preventable infections, and this review describes the application of oral fluid assays in support of mumps, rubella and varicella national immunization programs. In England and Wales individuals with suspected mumps or rubella, based on clinical presentation, can have an oral fluid swab sample taken for case confirmation. Universal varicella immunization of children has led to a drastic reduction of chickenpox in those countries where it is used; however, in England and Wales such a policy has not been instigated. Consequently, in England and Wales most children have had chickenpox by age 10 years; however, small, but significant, numbers of adults remain susceptible. Targeted varicella zoster virus (VZV immunization of susceptible adolescents offers the potential to reduce the pool of susceptible adults and oral fluid determination of VZV immunity in adolescents is a potential means of identifying susceptible individuals in need of VZV vaccination. The main application of oral fluid testing is in those circumstances where blood sampling is deemed not necessary, or is undesirable, and when the documented sensitivity and specificity of the oral fluid assay methodology to be used is considered sufficient for the purpose intended.

  16. No demonstrable association between the Leningrad-Zagreb mumps vaccine strain and aseptic meningitis in a large clinical trial in Egypt.

    Sharma, H J; Oun, S Aly; Bakr, S S Abou; Kapre, S V; Jadhav, S S; Dhere, R M; Bhardwaj, S

    2010-04-01

    To address the claim that the Leningrad-Zagreb (L-Z) mumps vaccine strain is causally associated with aseptic meningitis, a prospective, post-marketing safety study was conducted with a measles-mumps-rubella vaccine (MMR) (TRESIVAC(R); Serum Institute of India Ltd., Pune, India), which uses the L-Z strain as its mumps component in Egypt. In all, 453 119 children (65 423 children aged 16-24 months and 329 211 children aged 5-7 years) received MMR. The control groups which, as a result of local health regulations, were slightly younger than vaccinees, comprised 12 253 and 46 232 children, respectively. Using questionnaires, the parents recorded solicited local, systemic and neurological adverse events for up to 42 days post-vaccination. All data were analysed externally on an intention-to-treat basis by individuals not participating in the study. Local and/or systemic reactions were reported in a small percentage of participants, with pain, fever and parotitis being the most common signs among vaccinees in both age groups. No case of aseptic meningitis, encephalitis, anaphylaxis or convulsions was observed in any participant. Thus, in this series of more than 450 000 Egyptian children, the L-Z mumps vaccine strain in this vaccine did not cause aseptic meningitis. The vaccine is considerably cheaper than Western competitors and a valid alternative to other MMR vaccines.

    Measles continues to persist as one of the leading causes of infant mortality due to preventable diseases through vaccination. This study aims to highlight measles in Morocco, and to present the vaccination strategy implemented to control and eliminate the disease in this country. Throughout this study, and based on data from the Directorate of Epidemiology and Control of Diseases and those of the Directorate of Population, we present an overview on the epidemiological trends of measles from 1997 to 2012, while evoking the plans established by the Ministry of Health (MoH) for the control and elimination of this disease. The number of measles cases has decreased in Morocco between 1997 and 2012 (2574-720 reported cases per year) as a result of four important steps: first, increasing the routine vaccination coverage (73-94%); second, the introduction of the second dose of the combined vaccine against measles and rubella in schools (children aged 6 years) since 2003; third, the first catch-up campaign of vaccination in Morocco in 2008, for which coverage was highly satisfactory (96% and 100% for age groups 5-59 months and 5-14 years, respectively); and fourth, the organization of a mass vaccination campaign in 2013 that targeted children from aged 9 months to 19 years. The vaccination plan and the surveillance system executed in Morocco within the framework of the regional project implemented by the World Health Organization (WHO) to eliminate measles has given remarkable results regarding the reduction of measles cases and mortality due to this disease. According to the data from MoH and WHO, the number of reported and confirmed measles cases decreased drastically during 2014. However, these efforts are still unsatisfactory compared to the prospective of eliminating the disease by 2015.

  18. Measles epidemic in Brazil in the post-elimination period: Coordinated response and containment strategies.

    The measles virus circulation was halted in Brazil in 2001 and the country has a routine vaccination coverage against measles, mumps and rubella higher than 95%. In Ceará, the last confirmed case was in 1999. This article describes the strategies adopted and the effectiveness of surveillance and control measures implemented during a measles epidemic in the post-elimination period. The epidemic started in December 2013 and lasted 20 months, reaching 38 cities and 1,052 confirmed cases. The D8 genotype was identified. More than 50,000 samples were tested for measles and 86.4% of the confirmed cases had a laboratory diagnosis. The beginning of an campaign vaccination was delayed in part by the availability of vaccine. The classic control measures were not enough to control the epidemic. The creation of a committee of experts, the agreement signed between managers of the three spheres of government, the conducting of an institutional active search of suspected cases, vaccination door to door at alternative times, the use of micro planning, a broad advertising campaign at local media and technical operative support contributed to containing the epidemic. It is important to recognize the possibility of epidemics at this stage of post-elimination and prepare a sensitive surveillance system for timely response. Copyright © 2017 Elsevier Ltd.

  19. An Agent-Based Model of School Closing in Under-Vacccinated Communities During Measles Outbreaks.

    Getz, Wayne M; Carlson, Colin; Dougherty, Eric; Porco Francis, Travis C; Salter, Richard

    2016-04-01

    The winter 2014-15 measles outbreak in the US represents a significant crisis in the emergence of a functionally extirpated pathogen. Conclusively linking this outbreak to decreases in the measles/mumps/rubella (MMR) vaccination rate (driven by anti-vaccine sentiment) is critical to motivating MMR vaccination. We used the NOVA modeling platform to build a stochastic, spatially-structured, individual-based SEIR model of outbreaks, under the assumption that R 0 ≈ 7 for measles. We show this implies that herd immunity requires vaccination coverage of greater than approximately 85%. We used a network structured version of our NOVA model that involved two communities, one at the relatively low coverage of 85% coverage and one at the higher coverage of 95%, both of which had 400-student schools embedded, as well as students occasionally visiting superspreading sites (e.g. high-density theme parks, cinemas, etc.). These two vaccination coverage levels are within the range of values occurring across California counties. Transmission rates at schools and superspreading sites were arbitrarily set to respectively 5 and 15 times background community rates. Simulations of our model demonstrate that a 'send unvaccinated students home' policy in low coverage counties is extremely effective at shutting down outbreaks of measles.

  20. Parental attitudes towards measles vaccination in the canton of Aargau, Switzerland: a latent class analysis.

    Weiss, Carine; Schröpfer, Daniel; Merten, Sonja

    2016-08-11

    Despite the successes of routine national childhood vaccination programmes, measles remains a public health concern. The purpose of this paper is to investigate how patterns of parental attitudes are linked to the decision-making process for or against MMR vaccination. This exploratory study was designed to identify distinct patterns of attitudes towards or against measles vaccination through Latent Class Analysis (LCA) in a sub-sample of mothers living in the canton of Aargau in Switzerland. Parents of young children below 36 months of age were randomly selected through parents' counsellors' registries. Among other questions, respondents were asked to state their agreement in response to 14 belief statements regarding measles vaccination on a 5-point Likert scale. To identify groups of parents showing distinct patterns of attitudes and beliefs regarding measles vaccination, we used Latent Class Analysis (LCA). The LCA showed three classes of parents with different attitudes and believes towards measles vaccination: The biggest group (class 1) are those having positive attitudes towards immunisation, followed by the second biggest group (class 2) which is characterised by having fearful attitudes and by showing uncertainty about immunisation. The third group (class 3) shows distinct patterns of critical attitudes against immunisation. Within this group over 90 % agree or totally agree that immunisation is an artificial intrusion into the natural immune system and therefore want to vaccinate their children only if necessary. We find that parents in the Canton Aargau who hesitate to vaccinate their children against measles, mumps and rubella show distinct opinions and attitudes. Health professionals should be aware of these perceptions to tailor their messages accordingly and positively influence these parents to vaccinate their children. Special attention needs to be given to those parents who are planning to vaccinate their children but are not following the

  1. [Measles in Poland in 2004].

    2006-01-01

    In Poland 11 measles cases were registered in 2004 (0.03 per 100,000 population), of which 3 were cases imported from Chechnya. Of 8 local cases, 3 cases occurred in unvaccinated persons, 2 in persons vaccinated with one dose and 3 in vaccinated with two doses of measles vaccine (administered at the age of 13-15 months and 7 years). The most affected age groups were 1-year old children (0.29 per 100,000 population) and 6-year olds (0.25). Out of 11 reported cases 2 were hospitalized. There were no deaths attributed to measles. Poland participates in the WHO Measles Elimination Strategy. Presently, the most important is the maintenance of a sensitive and timely surveillance of measles and measles-compatible cases, with serologic testing of one suspect case per 100,000 population. The performance of the surveillance system was insufficient with only 44 measles-compatible cases reported in 2004 (12% of expected reports). Serologic confirmation of cases was also insufficient, with 5 cases confirmed in WHO accredited laboratory. These results indicate the need to maintain the high immunisation coverage and improve measles surveillance system.

  2. Updated recommendations for isolation of persons with mumps.

    2008-10-10

    Mumps, an acute vaccine-preventable viral illness transmitted by respiratory droplets and saliva, has an incubation period most commonly of 16-18 days. The classic clinical presentation of mumps is parotitis, which can be preceded by several days of nonspecific prodromal symptoms; however, mumps also can be asymptomatic, especially in young children. Mumps transmission can occur from persons with subclinical or clinical infections and during the prodromal or symptomatic phases of illness. In 2006, during a mumps resurgence in the United States, the latest national recommendations from CDC and the American Academy of Pediatrics (AAP) stipulated that persons with mumps be maintained in isolation with standard precautions and droplet precautions for 9 days after onset of parotitis. However, the existence of conflicting guidance (i.e., that the infectious period of mumps extended through the fourth day after parotitis onset) led to confusion regarding the appropriate length of isolation. In addition, during the 2006 resurgence, compliance with recommendations for isolation in university settings was substantially lower for 9 days (65%) compared with 4-5 days (86%). In 2007, after a review of the evidence supporting the 9-day isolation guidance by AAP and CDC, AAP changed its isolation guidance for health-care workers in ambulatory settings from 9 days to 5 days. In February 2008, after review of data on mumps in health-care settings, mumps viral load, and mumps virus isolation, the Healthcare Infection Control Practices Advisory Committee (HICPAC) approved changes in its recommendations related to mumps in in-patient settings. As a result, CDC, AAP, and HICPAC all now recommend a 5-day period after onset of parotitis, both for isolation of persons with mumps in either community or health-care settings and for use of standard precautions and droplet precautions. This report summarizes the scientific basis for these changes in mumps isolation guidance.

    We report on three cases of symptomatic transmission of the L-Zagreb mumps vaccine virus from three vaccinated children to five adult contacts. The five contact cases were parents of the vaccinated children and presented with parotitis and in one case also with aseptic meningitis. The etiology of the contacts' illness was determined by viral culture, genomic sequencing, serology and epidemiological linking. Two of the vaccinated children developed vaccine associated parotitis as an adverse event three weeks following immunization. Symptoms in contact cases developed five to seven weeks after the vaccination of the children. The five contact cases, as well as the three children with adverse events recovered completely. The children had been vaccinated with MMR vaccine produced by the Institute of Immunology Zagreb, each of them with a different lot. One of the possible explanations for these adverse events is that the very low levels of wild mumps virus circulation in the last decade, combined with waning immunity in those who received one dose of vaccine or suffered from mumps in childhood, resulted in susceptible young adults and that this unique epidemiological situation allows us to detect horizontal transmission of mumps vaccine virus.

    2009-02-05

    Mumps virus infection is a potentially serious viral infection of childhood and early adulthood. In China, live attenuated S(79) mumps vaccine has been licensed for pediatric use since 1990. The objective of this study was to determine the effectiveness of live attenuated S(79) mumps vaccine against clinical mumps in outbreaks. Cases were selected from mumps outbreaks in schools in Guangzhou between 2004 and 2005. Each case was matched by gender, age and classroom. Vaccination information was obtained from Children's EPI Administrative Computerized System. Vaccine effectiveness (VE) was calculated for 1 or 2 doses of S(79) vaccine with 95% confidence intervals (CI). One hundred and ninety-four cases and 194 controls were enrolled into the study. VE of the S(79) mumps vaccine for 1 dose versus 0 confer protection 80.4% (95% CI, 60.0%-90.4%) and VEs against mumps in outbreaks for 1 dose of mumps vaccine are similar among those children aged 4-9 years and aged over 10 years old. The live attenuated S(79) mumps vaccine can be effective in preventing clinical mumps outbreaks.

  5. Low titers of measles antibody in mothers whose infants suffered from measles before eligible age for measles vaccination

    Wu Qiaozhen

    2010-05-01

    Full Text Available Abstract Background Resurgence or outbreak of measles recently occurred in both developed and developing countries despite long-standing widespread use of measles vaccine. Measles incidence in China has increased since 2002, particularly in infants and in persons ≥ 15 years of age. It is speculated that infants may acquire fewer measles IgG from their mothers, resulting in the reduced duration of protection during their early months of life. This study aimed to clarify the reason of increased susceptibility to measles in young infants in China. Measles IgG in 24 measles infants ≤ 9 months of age and their vaccinated mothers was quantitatively measured. The mean measles neutralizing titer in the vaccinated mothers and in 13 age-match women with the histories of clinical measles were compared. Results All the mothers were confirmed to be vaccinated successfully by the presence of measles IgG. Six vaccinated mothers were positive for measles IgM and had high concentrations of measles IgG and the neutralizing antibody, indicating underwent natural boosting. The mean measles neutralizing titer in 18 vaccinated mothers without natural boosting were significantly lower than that in 13 age-match women with the histories of clinical measles (1:37 vs 1:182, P Conclusions Our results suggest that infants born to mothers who acquired immunity to measles by vaccination may get a relatively small amount of measles antibody, resulting in loss of the immunity to measles before the vaccination age. Measures to improve the immunity in young infants not eligible for measles vaccination would be critical to interrupt the measles transmission in China.

  6. [Measles in Poland in 2003].

    Stefanoff, Paweł; Czarkowski, Mirosław P

    2005-01-01

    In Poland 48 measles cases were registered in 2003 (0.13 per 100,000 population)--of which 65% were cases imported from Chechnya and Afghanistan. Measles outbreaks occurred in 3 centers for immigrants. In total, 31 cases were reported, of which 96.8% were unvaccinated, and 93.5% were under 15 years of age. Of 17 local cases, 5 (29.4%) cases occurred in unvaccinated persons, 3 (17.6%) in persons vaccinated with one dose and 7 (41.2%) in those vaccinated with two doses of measles vaccine (administered at the age of 13-15 months and 7 years). Among 12 vaccinated cases only one 2-year old child was recently vaccinated. The remaining cases were in the 3-7 and 10-24 age ranges. The most affected were infants (incidence 0.57 per 100,000), 1-year old (0.28) and 2-year old children (incidence 0.27). Cases among adolescents and adults over 15 years of age increased from 23.5% in 2002 to 47.1% in 2003. The increasing age of locally-acquired cases, together with constantly high immunization coverage indicates high effectiveness of vaccinations in Poland. Out of all reported cases 13 (38%) were hospitalized. There were no deaths due to measles in Poland in 2003. Poland participates in the WHO Measles Elimination Strategy. Presently, the most important is the maintenance of a sensitive and timely surveillance of measles and measles-compatible cases, with serologic confirmation of one rash-like illness per 100 000 population. The performance of the surveillance system is insufficient with only 55 measles-compatible cases reported in 2003 (15% of expected reports). Serologic confirmation of cases was also insufficient, with 22 cases (40.0%) confirmed by IgM ELISA test. These results indicate the need to maintain the high immunisation coverage and improve measles surveillance system.

  7. Measles: summary of worldwide impact.

    Assaad, F

    1983-01-01

    Nearly every measles infection results in well-recognized clinical disease. In nonimmunized populations almost every child will get measles early in life. The universality of the disease in nonimmunized communities, particularly those in the developing world, has led to a more or less passive acceptance of measles as an unavoidable risk of early life. The clinical spectrum of measles ranges from a mild, self-limiting illness to a fatal disease. Conditions encountered mainly in the developing world, e.g., unfavorable nutrition, high risk of concurrent infection, and inadequate case management -- particularly at home -- favor the development of complications and adverse outcome. Conversely, good clinical management of an otherwise healthy child, a situation seen mostly in the developed world, greatly influences the course of the disease. Hence many in the medical profession believe that measles is a mild disease except among populations living under particularly unfavorable conditions. Measles vaccine is effective in preventing disease in the individual and in controlling it in the community if it is given at the critical age when maternal antibodies wane and the risk of natural infection increases sharply and if a high immunization rate is maintained in the target population. The experience with immunization, particularly in sub-saharan Africa, is rewarding: mothers who had previously accepted measles as an unavoidable risk clamour for immunization of their children once its effectiveness has been demonstrated. No reason exists for measles to claim its present toll of morbidity and mortality. With extension of the Expanded Programme on Immunization of the World Health Organization, the impact of measles should progressively decline.

  10. Pericardial Tamponade in an Adult Suffering from Acute Mumps Infection

    Sascha Kahlfuss

    2016-01-01

    Full Text Available Here, we report a case of a 51-year-old man with acute pericardial tamponade requiring emergency pericardiocentesis after he suffered from sore throat, headache, malaise, and sweats for two weeks. Serological analyses revealed increased mumps IgM and IgG indicating an acute mumps infection whereas other bacterial and viral infections were excluded. In addition, MRI revealed atypical swelling of the left submandibular gland. Whereas mumps has become a rare entity in children due to comprehensive vaccination regimens in western civilizations, our case highlights mumps as an important differential diagnosis also in adults, where the virus can induce life-threatening complications such as pericardial tamponade.

    The aim of the study was to investigate effectiveness of mumps MMR component in communities with high MMR coverage. Outbreak-related cases of mumps born between 1995 and 2005 notified to Navarre and Catalonia public health services during the period 2005-2007 were studied. Vaccine effectiveness (VE) and their 95%CI were calculated using the screening method. Of 47 confirmed, 85.1% immunized with at least one dose (1MMR) and 44.9% with two (2MMR). Estimated VE was 85.4% (95%CI: 67.3-93.4) for 1MMR and 88.5% (95%CI: 78.1-93.9) for 2MMR. High 2MMR coverage, improved confirmation techniques and further VE studies with all confirmed cases are needed to prevent further outbreaks. (c) 2010 Elsevier Ltd. All rights reserved.

  13. Impacts of a measles outbreak in Western Sydney on public health resources.

    Flego, Kristina L; Belshaw, Daniel A; Sheppeard, Vicky; Weston, Kathryn M

    2013-09-30

    During February and March 2011, an outbreak of 26 confirmed cases of measles was reported to the Parramatta Public Health Unit (PHU) in western Sydney. This paper describes the impact of the outbreak on PHU resources. A retrospective review of information obtained from case notification forms and associated contact tracing records was carried out for each of the confirmed cases. Seven cases (27%) required hospital admission for more than 1 day and 10 (38%) cases required management within a hospital emergency department. There were no cases of encephalitis or death. The number of contacts was determined for each case as well as the number who required post-exposure prophylaxis. In total, 1,395 contacts were identified in this outbreak. Of these, 79 (5.7%) required normal human immunoglobulin and 90 (6.5%) were recommended to receive the measles-mumps-rubella vaccine. A case study detailing the PHU costs associated with the contact management of a hospitalised measles case with 75 identified contacts is also included and the estimated total cost to the PHU of containing this particular case of measles was A$2,433, with staff time comprising the major cost component. Considerable effort and resources are required to manage measles outbreaks. The total cost of this outbreak to the PHU alone is likely to have exceeded A$48,000. This work is copyright.

  14. Mumps vaccine failure investigation in Novosibirsk, Russia, 2002-2004.

    Atrasheuskaya, A V; Kulak, M V; Rubin, S; Ignatyev, G M

    2007-07-01

    The aims of this study were to estimate the importance of vaccine failure (VF) in cases of mumps during 2002-2004 in the city of Novosibirsk, Western Siberia, Russia, and to genotype the responsible virus strain. Mumps virus-specific RT-PCR testing of saliva was performed for 18 cases of mumps. Sera were tested for IgM and IgG, IgG avidity, and the ability to neutralise a panel of mumps viruses, including the Leningrad-3 mumps vaccine virus. Of the 12 patients for whom vaccination status was positively determined, 11 showed serological evidence of primary VF. Sequence analysis of virus RNA amplified from saliva revealed a genotype C2 virus in 2002, a genotype H2 virus in 2003, and both genotypes in 2004. Although several vaccinated patients were positive for mumps virus IgG at the time of first sampling, only nominal levels of neutralising antibody were detected, and these were effective in neutralising the vaccine strain, but not genotype C and H mumps virus strains. These results suggest that the majority of cases of mumps in vaccinees are caused by primary VF, defined as either a lack of seroconversion or a lack of IgG maturity, as based on avidity testing. The results also support the hypothesis that sera of low neutralising antibody titre have a limited ability to neutralise heterologous mumps virus strains, suggesting that antigenic differences between circulating and mumps vaccine virus strains may play a role in cases of breakthrough infection. Consistent with previous reports, mumps virus genotypes C and H continue to circulate in Novosibirsk.

  15. Assessment of coverage levels of single dose measles vaccine

    Tariq, P.

    2003-01-01

    Objective: To study the consequences of low coverage levels of a single dose of measles vaccine. Results: mean age observed in measles cases was 2 years and 8 months with a range from 3 months to 8 years. Maximum number of cases reported were <1 year of age (n=22,32%). Fifty percent of cases were seen among vaccinated children. Seventy-five percent (n=51) had history of contact with a measles case. Pneumonia was the commonest complication followed by acute gastroenteritis, encephalitis, febrile convulsions, oral ulcers, oral thrush, eye changes of vitamin-A deficiency and pulmonary tuberculosis (T.B.) in descending order of frequency. Fifty four cases were successfully treated for complications of measles and discharged. Nine cases left against medical advice. Five patients died all of them had encephalitis either alone (n=1) or in combination with pneumonia and acute gastroenteritis (n=4). Conclusion: There is a dire need to increase the immunization coverage to reduce the rate of vaccine failure and achieve effective control of measles.(author)

  16. The average cost of measles cases and adverse events following vaccination in industrialised countries

    2002-09-01

    Full Text Available Abstract Background Even though the annual incidence rate of measles has dramatically decreased in industrialised countries since the implementation of universal immunisation programmes, cases continue to occur in countries where endemic measles transmission has been interrupted and in countries where adequate levels of immunisation coverage have not been maintained. The objective of this study is to develop a model to estimate the average cost per measles case and per adverse event following measles immunisation using the Netherlands (NL, the United Kingdom (UK and Canada as examples. Methods Parameter estimates were based on a review of the published literature. A decision tree was built to represent the complications associated with measles cases and adverse events following imminisation. Monte-Carlo Simulation techniques were used to account for uncertainty. Results From the perspective of society, we estimated the average cost per measles case to be US$276, US$307 and US$254 for the NL, the UK and Canada, respectively, and the average cost of adverse events following immunisation per vaccinee to be US$1.43, US$1.93 and US$1.51 for the NL, UK and Canada, respectively. Conclusions These average cost estimates could be combined with incidence estimates and costs of immunisation programmes to provide estimates of the cost of measles to industrialised countries. Such estimates could be used as a basis to estimate the potential economic gains of global measles eradication.

    2007-11-01

    Full Text Available Introduction: Measels, Mumps and Rubella (MMR are highly contagious infectious diseases which may lead to severe complications. These diseases are vaccine-preventable. The present Health Technology Assessment report (report on technological consequences, HTA report was commissioned by the German Institute of Medical Documentation and Information (DIMDI and addresses various aspects of the MMR vaccination, the key question being how the MMR immunisation coverage rate can be increased in Germany. Objectives: The objectives of this report were to describe the benefits of the MMR vaccination for Germany and to analyse how the desired MMR immunisation coverage of >95% can be achieved. Methods: A systematic literature search was performed in 29 literature data bases. Particularly for epidemiological data and information on vaccination programs, this systematic search was supplemented by an extensive hand search, written and oral enquiries, as well as interviews with experts. A total of 200 texts were used to prepare this report. Results: At 92.5% (as of 2004 based on the whole of Germany, the current immunisation coverage for measles in children is above the weighted EC-15-average of 90.67%. Statements can only be made regarding the probability of illness for measles, as no data is available for mumps and rubella. With 2.8 infections (per 100,000 residents in 2006, Germany has not achieved the WHO target. Of cases submitted to the laboratory, only 32% were validated by diagnostic laboratory findings and 45% confirmed clinical-epidemiologically. There are only few economic analyses of vaccination programs in Germany. In international publications, mainly measels are validated economically. An analysis of the cost of measles for Germany shows potential cost savings. Unfortunately, no complete economic evaluation (cost-effectiveness, cost-benefit, or cost-utility analyses for MMR vaccination has been performed for Germany. Analyses conducted in the US

  5. Development of the Global Measles Laboratory Network.

    Featherstone, David; Brown, David; Sanders, Ray

    2003-05-15

    The routine reporting of suspected measles cases and laboratory testing of samples from these cases is the backbone of measles surveillance. The Global Measles Laboratory Network (GMLN) has developed standards for laboratory confirmation of measles and provides training resources for staff of network laboratories, reference materials and expertise for the development and quality control of testing procedures, and accurate information for the Measles Mortality Reduction and Regional Elimination Initiative. The GMLN was developed along the lines of the successful Global Polio Laboratory Network, and much of the polio laboratory infrastructure was utilized for measles. The GMLN has developed as countries focus on measles control activities following successful eradication of polio. Currently more than 100 laboratories are part of the global network and follow standardized testing and reporting procedures. A comprehensive laboratory accreditation process will be introduced in 2002 with six quality assurance and performance indicators.

    Postvaccination immunity was studied in the children and teenagers without a history of clinical mumps infection, who had been immunized with the Leningrad-3 mumps vaccine. The level of specific lgG in ELISA and that and spectrum of their neutralizing activity against a vaccine strain and three heterologous mumps virus (MV) strains (genotypes A, C, and H) were measured. The investigation included 151 sera from the vaccinees aged 3 to 17 years, possessing the detectable specific IgG titers in ELISA and the detectable neutralizing titers against the vaccine strain. 97.4% of the vaccinees had neutralizing activity against 1-3 heterologous MV strains. A preponderance of neutralizing titers against heterologous MV strains by 1-log2 in some sera (6.5-32.5 depending on age) was most likely to suggest that the vaccinees' had been in contact with these virus strains in the past. In our investigation, a combination of positive IgG titers and neutralizing titers against the vaccine strain 2-log2 or higher provided the protection of the vaccinated children and teenagers against the symptomatic infection. There was a pronounced buster effect of the second immunization and a drop in the neutralizing activity of the sera from the vaccinated children and adolescents over time after the first and second immunization.

    Koester, D. A.; Markus, K. W.; Dhuler, V.; Mahadevan, R.; Cowen, A.

    1995-01-01

    In order to help provide access to advanced micro-electro-mechanical systems (MEMS) technologies and lower the barriers for both industry and academia, the Microelectronic Center of North Carolina (MCNC) and ARPA have developed a program which provides users with access to both MEMS processes and advanced electronic integration techniques. The four distinct aspects of this program, the multi-user MEMS processes (MUMP's), the consolidated micro-mechanical element library, smart MEMS, and the MEMS technology network are described in this paper. MUMP's is an ARPA-supported program created to provide inexpensive access to MEMS technology in a multi-user environment. It is both a proof-of-concept and educational tool that aids in the development of MEMS in the domestic community. MUMP's technologies currently include a 3-layer poly-silicon surface micromachining process and LIGA (lithography, electroforming, and injection molding) processes that provide reasonable design flexibility within set guidelines. The consolidated micromechanical element library (CaMEL) is a library of active and passive MEMS structures that can be downloaded by the MEMS community via the internet. Smart MEMS is the development of advanced electronics integration techniques for MEMS through the application of flip chip technology. The MEMS technology network (TechNet) is a menu of standard substrates and MEMS fabrication processes that can be purchased and combined to create unique process flows. TechNet provides the MEMS community greater flexibility and enhanced technology accessibility.

  10. High Concentrations of Measles Neutralizing Antibodies and High-Avidity Measles IgG Accurately Identify Measles Reinfection Cases

    Rota, Jennifer S.; Hickman, Carole J.; Mercader, Sara; Redd, Susan; McNall, Rebecca J.; Williams, Nobia; McGrew, Marcia; Walls, M. Laura; Rota, Paul A.; Bellini, William J.

    2016-01-01

    In the United States, approximately 9% of the measles cases reported from 2012 to 2014 occurred in vaccinated individuals. Laboratory confirmation of measles in vaccinated individuals is challenging since IgM assays can give inconclusive results. Although a positive reverse transcription (RT)-PCR assay result from an appropriately timed specimen can provide confirmation, negative results may not rule out a highly suspicious case. Detection of high-avidity measles IgG in serum samples provides laboratory evidence of a past immunologic response to measles from natural infection or immunization. High concentrations of measles neutralizing antibody have been observed by plaque reduction neutralization (PRN) assays among confirmed measles cases with high-avidity IgG, referred to here as reinfection cases (RICs). In this study, we evaluated the utility of measuring levels of measles neutralizing antibody to distinguish RICs from noncases by receiver operating characteristic curve analysis. Single and paired serum samples with high-avidity measles IgG from suspected measles cases submitted to the CDC for routine surveillance were used for the analysis. The RICs were confirmed by a 4-fold rise in PRN titer or by RT-quantitative PCR (RT-qPCR) assay, while the noncases were negative by both assays. Discrimination accuracy was high with serum samples collected ≥3 days after rash onset (area under the curve, 0.953; 95% confidence interval [CI], 0.854 to 0.993). Measles neutralizing antibody concentrations of ≥40,000 mIU/ml identified RICs with 90% sensitivity (95% CI, 74 to 98%) and 100% specificity (95% CI, 82 to 100%). Therefore, when serological or RT-qPCR results are unavailable or inconclusive, suspected measles cases with high-avidity measles IgG can be confirmed as RICs by measles neutralizing antibody concentrations of ≥40,000 mIU/ml.

  11. Autophagy in Measles Virus Infection

    Aurore Rozières

    2017-11-01

    Full Text Available Autophagy is a biological process that helps cells to recycle obsolete cellular components and which greatly contributes to maintaining cellular integrity in response to environmental stress factors. Autophagy is also among the first lines of cellular defense against invading microorganisms, including viruses. The autophagic destruction of invading pathogens, a process referred to as xenophagy, involves cytosolic autophagy receptors, such as p62/SQSTM1 (Sequestosome 1 or NDP52/CALCOCO2 (Nuclear Dot 52 KDa Protein/Calcium Binding And Coiled-Coil Domain 2, which bind to microbial components and target them towards growing autophagosomes for degradation. However, most, if not all, infectious viruses have evolved molecular tricks to escape from xenophagy. Many viruses even use autophagy, part of the autophagy pathway or some autophagy-associated proteins, to improve their infectious potential. In this regard, the measles virus, responsible for epidemic measles, has a unique interface with autophagy as the virus can induce multiple rounds of autophagy in the course of infection. These successive waves of autophagy result from distinct molecular pathways and seem associated with anti- and/or pro-measles virus consequences. In this review, we describe what the autophagy–measles virus interplay has taught us about both the biology of the virus and the mechanistic orchestration of autophagy.

  13. Not all that rashes is measles:

    Ibrahim, S. A.; Mustafa, O. A.

    1998-01-01

    Measles is a major cause of infant mortality in third world countries, leading to approximately one million deaths each year. The WHO aims to globally eradicate measles virus at the beginning of the next century, which will need a major effort in particular in countries like Sudan. To achieve goal epidemiological studies I am needed to estimate the magnitude of the problem for which accurate diagnostic test are needed. We therefore conducted a study in El hag Yousif area (population 500 000) in Khartoum North where measles is prevalent despite vaccination effort by EPI. We studied the accuracy of the WHO criteria for clinical diagnosis in comparison with laboratory diagnosis during a one-year period. A total of 145 under five suspected measles cases were identified by active, case finding and examined. 111 cases fully complied with the WHO criteria for diagnosis of clinical measles. Out of 103 clinical measles cases, tested using prototype rapid measles test IgM Elisa and Pcr, 77(75%) were measles positive. A battery of virus test was run on 21 sera out of the 26(25%) measles negatives: Herpes virus-6, Epstein-Bar and Dengue viruses were detected in five, one and one case, respectively. It was concluded that one out of every four cases diagnosed by the clinical as measles rash is probably caused by other viruses. (Author)

    Vaidya, Sunil R.; Kamble, Madhukar B.; Chowdhury, Deepika T.; Kumbhar, Neelakshi S.

    2016-01-01

    Background & objectives: Under the outbreak-based measles surveillance in Maharashtra State the National Institute of Virology at Pune receives 3-5 serum samples from each outbreak and samples from the local hospitals in Pune for laboratory diagnosis. This report describes one year data on the measles and rubella serology, virus isolation and genotyping. Methods: Maharashtra State Health Agencies investigated 98 suspected outbreaks between January-December 2013 in the 20 districts. Altogether, 491 serum samples were received from 20 districts and 126 suspected cases from local hospitals. Samples were tested for the measles and rubella IgM antibodies by commercial enzyme immunoassay (EIA). To understand the diagnostic utility, a subset of serum samples (n=53) was tested by measles focus reduction neutralization test (FRNT). Further, 37 throat swabs and 32 urine specimens were tested by measles reverse transcription (RT)-PCR and positive products were sequenced. Virus isolation was performed in Vero hSLAM cells. Results: Of the 98 suspected measles outbreaks, 61 were confirmed as measles, 12 as rubella and 21 confirmed as the mixed outbreaks. Four outbreaks remained unconfirmed. Of the 126 cases from the local hospitals, 91 were confirmed for measles and three for rubella. Overall, 93.6 per cent (383/409) confirmed measles cases were in the age group of 0-15 yr. Measles virus was detected in 18 of 38 specimens obtained from the suspected cases. Sequencing of PCR products revealed circulation of D4 (n=9) and D8 (n=9) strains. Four measles viruses (three D4 & one D8) were isolated. Interpretation & conclusions: Altogether, 94 measles and rubella outbreaks were confirmed in 2013 in the State of Maharasthra indicating the necessity to increase measles vaccine coverage in the State.

    Mumps is a highly contagious human disease, characterized by lateral or bilateral nonsuppurative swelling of the parotid glands and neurological complications that can result in aseptic meningitis or encephalitis. A mumps vaccination program implemented since the 1960s reduced mumps incidence by more than 99% and kept the mumps case numbers as low as hundreds of cases per year in the United States before 2006. However, a large mumps outbreak occurred in vaccinated populations in 2006 and again in 2009 in the United States, raising concerns about the efficacy of the vaccination program. Previously, we have shown that clinical isolate-based recombinant mumps viruses lacking expression of either the V protein (rMuVΔV) or the SH protein (rMuVΔSH) are attenuated in a neurovirulence test using newborn rat brains (P. Xu et al., Virology 417:126-136, 2011, http://dx.doi.org/10.1016/j.virol.2011.05.003; P. Xu et al., J. Virol. 86:1768-1776, 2012, http://dx.doi.org/10.1128/JVI.06019-11) and may be good candidates for vaccine development. In this study, we examined immunity induced by rMuVΔSH and rMuVΔV in mice. Furthermore, we generated recombinant mumps viruses lacking expression of both the V protein and the SH protein (rMuVΔSHΔV). Analysis of rMuVΔSHΔV indicated that it was stable in tissue culture cell lines. Importantly, rMuVΔSHΔV was immunogenic in mice, indicating that it is a promising candidate for mumps vaccine development.

    Eleven mumps vaccine strains, all containing live attenuated virus, have been used throughout the world. Although L-Zagreb mumps vaccine has been licensed since 1972, only its partial nucleotide sequence was previously determined (accession numbers , and ). Therefore, we sequenced the entire genome of L-Zagreb vaccine strain (Institute of Immunology Inc., Zagreb, Croatia). In order to investigate the genetic stability of the vaccine, sequences of both L-Zagreb master seed and currently produced vaccine batch were determined and no difference between them was observed. A phylogenetic analysis based on SH gene sequence has shown that L-Zagreb strain does not belong to any of established mumps genotypes and that it is most similar to old, laboratory preserved European strains (1950s-1970s). L-Zagreb nucleotide and deduced protein sequences were compared with other mumps virus sequences obtained from the GenBank. Emphasis was put on functionally important protein regions and known antigenic epitopes. The extensive comparisons of nucleotide and deduced protein sequences between L-Zagreb vaccine strain and other previously determined mumps virus sequences have shown that while the functional regions of HN, V, and L proteins are well conserved among various mumps strains, there can be a substantial amino acid difference in antigenic epitopes of all proteins and in functional regions of F protein. No molecular pattern was identified that can be used as a distinction marker between virulent and attenuated strains.

  18. Measles vaccination in humanitarian emergencies: a review of recent practice

    Watson John

    2011-09-01

    Full Text Available Abstract Background The health needs of children and adolescents in humanitarian emergencies are critical to the success of relief efforts and reduction in mortality. Measles has been one of the major causes of child deaths in humanitarian emergencies and further contributes to mortality by exacerbating malnutrition and vitamin A deficiency. Here, we review measles vaccination activities in humanitarian emergencies as documented in published literature. Our main interest was to review the available evidence focusing on the target age range for mass vaccination campaigns either in response to a humanitarian emergency or in response to an outbreak of measles in a humanitarian context to determine whether the current guidance required revision based on recent experience. Methods We searched the published literature for articles published from January 1, 1998 to January 1, 2010 reporting on measles in emergencies. As definitions and concepts of emergencies vary and have changed over time, we chose to consider any context where an application for either a Consolidated Appeals Process or a Flash Appeal to the UN Central Emergency Revolving Fund (CERF occurred during the period examined. We included publications from countries irrespective of their progress in measles control as humanitarian emergencies may occur in any of these contexts and as such, guidance applies irrespective of measles control goals. Results Of the few well-documented epidemic descriptions in humanitarian emergencies, the age range of cases is not limited to under 5 year olds. Combining all data, both from preventive and outbreak response interventions, about 59% of cases in reports with sufficient data reviewed here remain in children under 5, 18% in 5-15 and 2% above 15 years. In instances where interventions targeted a reduced age range, several reports concluded that the age range should have been extended to 15 years, given that a significant proportion of cases occurred

  19. Genotype-Specific Measles Transmissibility: A Branching Process Analysis.

    Substantial heterogeneity in measles outbreak sizes may be due to genotype-specific transmissibility. Using a branching process analysis, we characterize differences in measles transmission by estimating the association between genotype and the reproduction number R among postelimination California measles cases during 2000-2015 (400 cases, 165 outbreaks). Assuming a negative binomial secondary case distribution, we fit a branching process model to the distribution of outbreak sizes using maximum likelihood and estimated the reproduction number R for a multigenotype model. Genotype B3 is found to be significantly more transmissible than other genotypes (P = .01) with an R of 0.64 (95% confidence interval [CI], .48-.71), while the R for all other genotypes combined is 0.43 (95% CI, .28-.54). This result is robust to excluding the 2014-2015 outbreak linked to Disneyland theme parks (referred to as "outbreak A" for conciseness and clarity) (P = .04) and modeling genotype as a random effect (P = .004 including outbreak A and P = .02 excluding outbreak A). This result was not accounted for by season of introduction, age of index case, or vaccination of the index case. The R for outbreaks with a school-aged index case is 0.69 (95% CI, .52-.78), while the R for outbreaks with a non-school-aged index case is 0.28 (95% CI, .19-.35), but this cannot account for differences between genotypes. Variability in measles transmissibility may have important implications for measles control; the vaccination threshold required for elimination may not be the same for all genotypes or age groups.

  20. Measles virus: Background and oncolytic virotherapy

    Sankhajit Bhattacharjee; Pramod Kumar Yadava

    2018-01-01

    Measles is a highly transmissible disease caused by measles virus and remains a major cause of child mortality in developing countries. Measles virus nucleoprotein (N) encapsidates the RNA genome of the virus for providing protection from host cell endonucleases and for specific recognition of viral RNA as template for transcription and replication. This protein is over-expressed at the time of viral replication. The C-terminal of N protein is intrinsically disordered, which enables this prot...

  1. The glycoprotein of measles virus

    Anttonen, O.; Jokinen, M.; Salmi, A.; Vainionpaeae, R.; Gahmberg, C.G.

    1980-01-01

    Measles virus was propagated in VERO cells and purified from the culture supernatants by two successive tartrate-density-gradient centrifugations. Surface carbohydrates were labelled both in vitro and in vivo with 3 H after treatment with galactose oxidase/NaB 3 H 4 or with [ 3 H]glucosamine. The major labelled glycoprotein in measles virions had a mol.wt. of 79000. After labelling with periodate/NaB 3 H 4 , which would result in specific labelling of sialic acid residues, the 79000-mol.wt. glycoprotein was very weakly labelled. This suggested that there is no or a very low amount of sialic acid in the virions. Further analysis of the glycoprotein showed that galactose is the terminal carbohydrate unit in the oligosaccharide, and the molecular weight of the glycopeptide obtained after Pronase digestion is about 3000. The oligosaccharide is attached to the polypeptide through an alkali-stable bond, indicating a N-glycosidic asparagine linkage. (author)

  2. Vaccine platform recombinant measles virus.

    Mühlebach, Michael D

    2017-10-01

    The classic development of vaccines is lengthy, tedious, and may not necessarily be successful as demonstrated by the case of HIV. This is especially a problem for emerging pathogens that are newly introduced into the human population and carry the inherent risk of pandemic spread in a naïve population. For such situations, a considerable number of different platform technologies are under development. These are also under development for pathogens, where directly derived vaccines are regarded as too complicated or even dangerous due to the induction of inefficient or unwanted immune responses causing considerable side-effects as for dengue virus. Among platform technologies are plasmid-based DNA vaccines, RNA replicons, single-round infectious vector particles, or replicating vaccine-based vectors encoding (a) critical antigen(s) of the target pathogens. Among the latter, recombinant measles viruses derived from vaccine strains have been tested. Measles vaccines are among the most effective and safest life-attenuated vaccines known. Therefore, the development of Schwarz-, Moraten-, or AIK-C-strain derived recombinant vaccines against a wide range of mostly viral, but also bacterial pathogens was quite straightforward. These vaccines generally induce powerful humoral and cellular immune responses in appropriate animal models, i.e., transgenic mice or non-human primates. Also in the recent first clinical phase I trial, the results have been quite encouraging. The trial indicated the expected safety and efficacy also in human patients, interestingly independent from the level of prevalent anti-measles immunity before the trial. Thereby, recombinant measles vaccines expressing additional antigens are a promising platform for future vaccines.

    2001-01-01

    Morphological and immunofluorescent study of changes in the central nervous system of monkeys with mumps was carried out in order to determine the criteria of neurovirulence of different mumps virus strains. Quantitative evaluation showed a lower residual neurovirulence of L-3 strain vs. Jeryl Lynn and Urabe Am9 strains. Use of new methodological approaches to evaluation of mumps vaccine strain neurovirulence will improve the safety control of live mumps vaccines.

    2015-09-25

    To analyse the epidemiology, serology and vaccine effectiveness in a recent New Zealand measles outbreak that started in Auckland, from December, 2013 to June, 2014, to guide further preventive measures. Cases had a clinically compatible illness, which was either confirmed by PCR or serology, or were linked to a laboratory confirmed case. A total of 113 cases with 3,113 contacts were traced and managed in the Auckland region. Thirteen overseas acquired cases, produced a total of 98 locally acquired secondary cases, (plus two cases with unknown travel history). The majority of cases occurred in adolescents and young adults; 68/113 cases (60.1%) were aged 10 to 19 years. Among cases, 38.9% (44/113) were unimmunised, and 31.8% (36/113) had unknown immunisation status. A further 15.0% (17/113) of cases had received one or two doses of measles, mumps, rubella (MMR) vaccine. Of the contacts who underwent serological testing for immunity (n=735), the lowest levels of serological immunity were observed in people aged 10 to 24 years. Vaccine effectiveness was calculated for the 15-24 year age cohort at 92% (95%CI; 82-97). Results suggest that an adolescent catch-up immunisation programme would prevent further outbreaks of imported measles.

  8. Knowledge synthesis of benefits and adverse effects of measles vaccination: the Lasbela balance sheet.

    Ledogar, Robert J; Fleming, John; Andersson, Neil

    2009-10-14

    In preparation for a cluster-randomized controlled trial of a community intervention to increase the demand for measles vaccination in Lasbela district of Pakistan, a balance sheet summarized published evidence on benefits and possible adverse effects of measles vaccination. The balance sheet listed: 1) major health conditions associated with measles; 2) the risk among the unvaccinated who contract measles; 3) the risk among the vaccinated; 4) the risk difference between vaccinated and unvaccinated; and 5) the likely net gain from vaccination for each condition. Two models revealed very different projections of net gain from measles vaccine. A Lasbela-specific combination of low period prevalence of measles among the unvaccinated, medium vaccination coverage and low vaccine efficacy rate, as revealed by the baseline survey, resulted in less-than-expected gains attributable to vaccination. Modelled on estimates where the vaccine had greater efficacy, the gains from vaccination would be more substantial. Specific local conditions probably explain the low rates among the unvaccinated while the high vaccine failure rate is likely due to weaknesses in the vaccination delivery system. Community perception of these realities may have had some role in household decisions about whether to vaccinate, although the major discouraging factor was inadequate access. The balance sheet may be useful as a communication tool in other circumstances, applied to up-to-date local evidence.

  9. Analysis of mumps vaccine failure by means of avidity testing for mumps virus-specific immunoglobulin G.

    1998-11-01

    To characterize patients with mumps vaccine failure, avidity testing was performed with the Enzygnost Anti-Parotitis Virus/IgG kit using a single-dilution-6 M urea denaturation method. Five groups of patients were tested. Group 1 consisted of 29 patients with primary mumps infections; group 2 was 20 children and adults with a definite history of natural infection; group 3 was 7 patients with a recent mumps vaccination, 1 of whom developed parotid gland swelling and aseptic meningitis; group 4 was 14 patients with mumps vaccine failure; and group 5 was 6 patients with recurrent episodes of parotitis in addition to a history of vaccination. On the basis of the results of groups 1 and 2, an avidity of /=32% was determined to be high. Avidity maturation from low to high appears to occur around 180 days after the acute illness. The results of group 3 showed that the vaccine-induced immunoglobulin G (IgG) had very low avidity. Among the 14 patients in group 4, 12 patients, including 7 with a positive IgM response, were diagnosed as having secondary vaccine failures. The results of group 5 suggested the possibility that the avidity of the mumps vaccine-induced IgG remains low or borderline. These results showed that secondary mumps vaccine failure occurs not infrequently, even among school age children under condition in which the vaccine coverage is low (i.e., 33% in our study population), and therefore, vaccinees are prone to be exposed to wild-type viruses. Avidity testing should provide information useful for the analysis of mumps virus infections.

  10. Vaccination of School Children With Live Mumps Virus Vaccine

    Furesz, J.; Nagler, F. P.

    1970-01-01

    Live, attenuated mumps virus vaccine (Mumpsvax) was administered to 146 school children 6 to 9 years of age. One child developed clinical mumps nine days after vaccination; epidemiological and serological data strongly suggest that this child had become infected before vaccination. Apart from this single instance there were no apparent clinical reactions that could be ascribed to the administration of the vaccine. Sixty-three of the 146 children with no clinical history of mumps had an initial serum neutralizing antibody titre of less than 1:2. Specific antibodies to mumps virus were detected in 93.5% of the sera of the susceptible children 28 days after vaccination, and the geometric mean antibody titre of these sera was low (1:6). Of the 80 initially seropositive children 21 (26.2%) showed a significant antibody response to the vaccine and this was influenced by the pre-existing antibody level. These data have further demonstrated the safety and efficacy of the live mumps vaccine in children. PMID:5420994

    Molecular characterization of measles viruses is a valuable tool for measuring the effectiveness of measles control and elimination programmes. WHO recommends that virological surveillance be conducted during all phases of measles control to document circulation of indigenous strains and trace future importation. This report describes the genetic characterization of wild type measles viruses from Tamil Nadu, India isolated between January 2005 and January 2006. In the study, 304 suspected measles cases (292 from 56 outbreaks and 12 sporadic cases) were investigated. Blood samples were collected from suspected measles outbreaks and 11 suspected sporadic cases and tested for the presence of measles and rubella specific IgM. Based on serological results, 53 outbreaks were confirmed as measles, 2 as a combination of measles and rubella, and 1 negative for both. Eight sporadic cases were confirmed as measles and one as rubella. Throat swab and urine samples were collected for virus isolation and 28 isolates were obtained. Sequencing and analysis showed that 3 isolates belonged to genotype D4 and 25 to genotype D8. Comparison of the genotype D8 sequences from Tamil Nadu with previously reported genotype D8 sequences from India and abroad showed six distinct clusters with Tamil Nadu strains forming two clusters. This study has established baseline molecular data and is the first report that describes genetic diversity of circulating measles strains in Tamil Nadu, a state in India. D8 has multiple lineages and this has been linked with importation of measles into the USA and UK. Copyright © 2011 Wiley Periodicals, Inc.

  18. Measles transmission in health care waiting rooms: implications for public health response

    Stephen Conaty

    2012-12-01

    Full Text Available Background: Seventeen cases of locally acquired measles occurred in South Western Sydney and Sydney local health districts between July and October 2011. Three of the cases were known to have at least one dose of measles-mumps-rubella (MMR vaccine. Seven cases were infected within a health care setting waiting room by five index cases. Current national protocols require follow-up of all susceptible contacts in the same waiting room for any length of time for up to two hours after the index case has left.Methods: Cases were interviewed using a standardized questionnaire. Information included: demographics, illness and activities during the exposure and infectious periods. Health care settings provided arrival and discharge times, maps of floor layouts and location of patients during stay.Results: All health care setting transmission occurred in cases who were present at the same time as their index cases, with cross-over time ranging from 20 to 254 minutes. No index case was isolated. Index cases were between day four and six of illness when transmission occurred. None of the five index cases and one of seven secondary cases had received at least one dose of MMR vaccine. Of the seven secondary cases, two were one year of age, one was 17 years old and four were between 30 and 39 years old.Conclusion: As Australia moves towards measles elimination, follow-up of cases is important; however, with limited public health resources a targeted response is vital. In this small but well-documented series of secondary cases acquired in a health care setting, all were infected following direct, proximate contact of at least 20 minutes. Changes to the national guidelines may be warranted, ensuring that limited resources are focused on following up contacts at greatest risk of disease.

    2014-01-01

    Background According to WHO estimates, 35% of global measles deaths in 2011 occurred in India. In 2013, India committed to a goal of measles elimination by 2020. Laboratory supported case based measles surveillance is an essential component of measles elimination strategies. Results from a case-based measles surveillance system in Pune district (November 2009 through December 2011) are reported here with wider implications for measles elimination efforts in India. Methods Standard protocols were followed for case identification, investigation and classification. Suspected measles cases were confirmed through serology (IgM) or epidemiological linkage or clinical presentation. Data regarding age, sex, vaccination status were collected and annualized incidence rates for measles and rubella cases calculated. Results Of the 1011 suspected measles cases reported to the surveillance system, 76% were confirmed measles, 6% were confirmed rubella, and 17% were non-measles, non-rubella cases. Of the confirmed measles cases, 95% were less than 15 years of age. Annual measles incidence rate was more than 250 per million persons and nearly half were associated with outbreaks. Thirty-nine per cent of the confirmed measles cases were vaccinated with one dose of measles vaccine (MCV1). Conclusion Surveillance demonstrated high measles incidence and frequent outbreaks in Pune where MCV1 coverage in infants was above 90%. Results indicate that even high coverage with a single dose of measles vaccine was insufficient to provide population protection and prevent measles outbreaks. An effective measles and rubella surveillance system provides essential information to plan, implement and evaluate measles immunization strategies and monitor progress towards measles elimination.

    In a mumps outbreak in the United States, many infected individuals were adults who had received 2 doses of mumps vaccine. The persistence of cellular immunity to mumps vaccine has not been defined. This was an observational, nonrandomized cohort study evaluating cell-mediated and humoral immunity to mumps in 10 vaccinated and 10 naturally immune adults. Mumps-specific T cell activation and interferon (IFN)-gamma production were measured using lymphoproliferative and flow cytometry assays, and mumps immunoglobulin (Ig) G was measured using enzyme-linked immunosorbent assay. T cell immunity to mumps was high in both groups; 70% of vaccinated and 80% of naturally immune individuals had a positive (> or =3) stimulation index (SI) (P = 1.0). The mean percentages of mumps-specific CD4+ T cells that expressed CD69 and produced IFN-gamma were equivalent in the 2 groups: 0.06% and 0.12%, respectively (P = .11). The mean SIs in the groups were also equivalent, although IFN-gamma concentrations from cultures stimulated with mumps antigen were higher in naturally immune adults than in vaccinated adults (P < or = .01). All adults were positive for mumps IgG. T and B cell immunity to mumps was detected in adults at least 10 years after immunization. Except for IFN-gamma release, responses in vaccinated adults paralleled those observed in naturally immune individuals.

    2006-03-06

    Here we describe symptomatic transmission of the Leningrad-3 mumps vaccine virus from healthy vaccinees to previously vaccinated contacts. Throat swab and serum samples were taken from six symptomatic mumps cases and from 13 family contacts. Assessment of serum IgG and IgM anti-mumps virus antibodies and IgG avidity testing was performed using commercial test kits. Sera neutralizing antibodies were measured by plaque reduction neutralization assay using the L-3 vaccine mumps virus as the target. All six of the symptomatic mumps cases and three contact subjects tested positive for mumps by RT-PCR. The genomic sequences tested (F, SH and HN genes) of all nine of these samples were identical to the L-3 mumps vaccine strain. All 13 contacts were asymptomatic; however clear serological evidence of mumps infection was found in some of them. The likely epidemiological source of the transmitted L-3 mumps virus was children who were recently vaccinated at the schools attended by the six symptomatic mumps patients described here. The L-3 mumps vaccine virus can be shed and transmitted horizontally, even to subjects previously vaccinated with the same virus.

    2002-05-01

    In Japan, freeze-dried live attenuated mumps vaccine has been used optionally since 1981. The effectiveness of mumps vaccination has been established by worldwide research since 1971. On the other hand, because of it's live activity several untoward effects have been reported. Vaccination-related mumps orchitis is a rare adverse effect of mumps vaccine. Only 9 cases of vaccination-related mumps orchitis have been reported in Japan. We describe a case of orchitis following mumps vaccination in adolescence. A 16 years-old male has admitted because of acute orchitis with high fever and painful swelling of right testis. The patient had received vaccination with freeze-dried live attenuated mumps vaccine 16 days before admission. After admission, the bed-rest had completely relieved the symptoms on 6th hospital day. The impaired testis has maintained normal size and consistency 6 months after discharge.

  4. Establishing a small animal model for evaluating protective immunity against mumps virus.

    Adrian Pickar

    Full Text Available Although mumps vaccines have been used for several decades, protective immune correlates have not been defined. Recently, mumps outbreaks have occurred in vaccinated populations. To better understand the causes of the outbreaks and to develop means to control outbreaks in mumps vaccine immunized populations, defining protective immune correlates will be critical. Unfortunately, no small animal model for assessing mumps immunity exists. In this study, we evaluated use of type I interferon (IFN alpha/beta receptor knockout mice (IFN-α/βR-/- for such a model. We found these mice to be susceptible to mumps virus administered intranasally and intracranially. Passive transfer of purified IgG from immunized mice protected naïve mice from mumps virus infection, confirming the role of antibody in protection and demonstrating the potential for this model to evaluate mumps immunity.

  5. Mumps outbreak in Israel's highly vaccinated society: are two doses enough?

    Anis, E; Grotto, I; Moerman, L; Warshavsky, B; Slater, P E; Lev, B

    2012-03-01

    Mumps outbreaks in recent years have given rise to questions about the effectiveness of the mumps vaccine. This study examined the epidemiological data from a recent mumps outbreak in Israel and from outbreaks in other countries with high vaccination coverage, and considered whether long-established vaccination policies designed to protect against mumps are in need of revision. Of over 5000 case patients in the Israeli outbreak, half of whom were in the Jerusalem health district, nearly 40% were aged ≥15 years and, of those whose vaccination status was known, 78% had been fully vaccinated for their age - features similar to those in recent mumps outbreaks in Europe and North America. The epidemiological and laboratory evidence suggests that many previously vaccinated adolescents and young adults are now susceptible to mumps because their vaccine-based immunity has waned. Booster vaccination programmes for those at high risk of infection during mumps outbreaks - particularly those in congregate living environments - merit priority consideration.

    2005-11-01

    The comparative efficacy of the three mumps vaccine strains (Jeryl-Lynn, Urabe and Rubini) was conducted in an Asian population from data arising from an epidemiological investigation of seven institutional outbreaks of mumps in Singapore. Demographic information (gender, age, ethnic group), clinical presentation and vaccination history (date and place of mumps vaccination, type of mumps vaccine received) of all children who attended the six childcare centres and one primary school where outbreaks of 20 or more cases of mumps occurred in 1999 were collected. The attack rate of the unvaccinated group and the attack rates of the vaccine groups (for each vaccine strain) were determined and the vaccine efficacy of the three vaccines calculated. The vaccine efficacy of the Jeryl-Lynn strain, Urabe strain and Rubini strain mumps vaccine were 80.7, 54.4 and -55.3%, respectively. Rubini strain mumps vaccine conferred no protection and has since been deregistered in Singapore.

    In the last decade, several mumps outbreaks were reported in various countries despite high vaccination coverage. In most cases, young adults were affected who have acquired immunity against mumps solely by vaccination and not by previous wild-type mumps virus infection. To investigate mumps-specific antibody levels, functionality and dynamics during a mumps epidemic, blood samples were obtained longitudinally from 23 clinical mumps cases, with or without a prior history of vaccination, and from 20 healthy persons with no serological evidence of recent mumps virus infection. Blood samples from mumps cases were taken 1-2 months and 7-10 months after onset of disease. Both vaccinated and unvaccinated mumps cases had significantly higher geomean concentrations of mumps-specific IgG (resp. 13,617 RU/ml (95% CI of 9,574-19,367 RU/ml) vs. 1,552 (445-5412) RU/ml at 1-2 months; and 6,514 (5,247-8,088) RU/ml vs. 1,143 (480-2,725) RU/ml at 7-10 months) than healthy controls (169 (135-210) RU/ml) (p = 0.001). Patterns in virus-neutralizing (VN) antibody responses against the mumps vaccine virus were similar, vaccinated and unvaccinated mumps cases had significantly higher ND50 values at both time points of sampling (resp 4,695 (3,779-5,832) RU/ml vs. 1,533 (832-2,825) RU/ml at 1-2 months; 2,478 (1,968-3,122) RU/ml vs. 1,221 (1,029-1,449) RU/ml at 7-10 months) compared with (previously vaccinated) healthy controls (122 (196-76)) RU/ml) (p = 0.001) The unvaccinated mumps cases had significantly lower mumps-specific IgG and VN antibody concentrations at both sampling points compared with previously vaccinated cases, but their antibody concentrations did not differ significantly at the 2 time points. In contrast, the mumps-specific IgG and VN antibody concentrations of the previously vaccinated mumps cases were significantly higher within the first 2 months after onset of mumps and declined thereafter, characteristic for a secondary response. A moderate correlation was found

  8. Global eradication of measles: Are we poised?

    2017-01-01

    Full Text Available Measles, a highly infectious viral disease is the next target for eradication following poliovirus. Decades of experience with highly effective vaccination has invigorated us to take on this virus. The task is not only Titanic but is laced with intricate issues. Recently, an outbreak of fever with rash occurred on a tertiary care teaching hospital campus and was confirmed serologically as measles outbreak by IgMELISA. Therefore, we searched the literature related to outbreaks, transmission of the measles virus, age groups involved, vaccination strategies, vaccination failure and epidemiological features of the disease and reviewed the possible reasons for such outbreaks and problems in the global eradication of the virus.

  9. Evidence of pestivirus RNA in human virus vaccines.

    Harasawa, R; Tomiyama, T

    1994-01-01

    We examined live virus vaccines against measles, mumps, and rubella for the presence of pestivirus RNA or of pestiviruses by reverse transcription PCR. Pestivirus RNA was detected in two measles-mumps-rubella combined vaccines and in two monovalent vaccines against mumps and rubella. Nucleotide sequence analysis of the PCR products indicated that a modified live vaccine strain used for immunization of cattle against bovine viral diarrhea is not responsible for the contamination of the vaccines.

  10. Girls may have lower levels of maternal measles antibodies and higher risk of subclinical measles infection before the age of measles vaccination

    Martins, Cesario; Bale, Carlitos; Garly, May-Lill

    2009-01-01

    BACKGROUND: Previous studies have suggested that girls may have lower maternal measles antibody levels than boys. Girls might therefore be more likely to contract measles infection before the normal age of measles vaccination at 9 months of age. METHODS: In connection with a clinical trial...... of different measles vaccination strategies, we collected pre-measles vaccination blood samples at 4.5 months of age from two subgroups of children. Samples from these children were used to assess possible differences in maternal antibody levels for boys and girls. At 9 months of age another subgroup...... of children was sampled before the normal measles vaccination; these samples were used to assess the frequency of subclinical measles infection among boys and girls. RESULTS: We determined measles-specific antibody levels for 812 children at 4.5 months of age and for 896 children at 9 months of age. At 4...

  11. Presumed Cases of Mumps in Pregnancy: Clinical and Infection Control Implications

    Svjetlana Lozo

    2012-01-01

    Full Text Available Recently, a mumps outbreak in New York and New Jersey was reported by the Centers for Disease Control and Prevention (CDC. Subsequently, the dissemination of the disease was rapid, and, from June 28th 2009 through January 29th 2010, a total of 1,521 cases of mumps were reported in New York and New Jersey. Seven presumed cases occurred in pregnant women cared for at our institution. Mumps diagnosis as per the NYC Department of Health and Mental Hygiene was based on clinical manifestations, particularly parotitis. Prior immunizations with mumps vaccine and negative IgM were not adequate to rule out mumps infections. All of our seven patients had exposure to mumps in either their household or their community, and some of the them had symptoms of mumps. Due to the difficulties in interpreting serologies of these patients, their cases led to a presumed diagnosis of mumps. The diagnosis of mumps lead to the isolation of patients and health care personnel that were in contact with them. In this paper, we detail the presenting findings, diagnostic dilemmas and infection control challenges associated with presumed cases of mumps in pregnancy.

  12. Cross-neutralization between three mumps viruses & mapping of haemagglutinin-neuraminidase (HN) epitopes.

    Vaidya, Sunil R; Dvivedi, Garima M; Jadhav, Santoshkumar M

    2016-01-01

    The reports from the countries where mumps vaccine is given as routine immunization suggest differences in mumps virus neutralizing antibody titres when tested with vaccine and wild type viruses. Such reports are unavailable from countries like India where mumps vaccine is not included in routine immunization. We, therefore, undertook this study to understand the cross-neutralization activity of Indian mumps viruses. By using commercial mumps IgG enzyme immunoassay (EIA) and a rapid focus reduction neutralization test (FRNT), a panel of serum samples was tested. The panel consisted of 14 acute and 14 convalescent serum samples collected during a mumps outbreak and 18 archived serum samples. Two wild types (genotypes C and G) and Leningrad-Zagreb vaccine strain (genotype N) were used for the challenge experiments and FRNT titres were determined and further compared. The HN protein sequence of three mumps viruses was analyzed for the presence of key epitopes. All serum samples effectively neutralized mumps virus wild types and a vaccine strain. However, significantly lower FRNT titres were noted to wild types than to vaccine strain (P<0.05). The comparison between EIA and FRNT results revealed 95.6 per cent agreement. No amino acid changes were seen in the epitopes in the Indian wild type strains. All potential N-linked glycosylation sites were observed in Indian strains. Good cross-neutralization activity was observed for three mumps virus strains, however, higher level of FRNT titres was detected for mumps virus vaccine strain compared to Indian wild type isolates.

  13. Measles to the Rescue: A Review of Oncolytic Measles Virus

    Sarah Aref

    2016-10-01

    Full Text Available Oncolytic virotherapeutic agents are likely to become serious contenders in cancer treatment. The vaccine strain of measles virus is an agent with an impressive range of oncolytic activity in pre-clinical trials with increasing evidence of safety and efficacy in early clinical trials. This paramyxovirus vaccine has a proven safety record and is amenable to careful genetic modification in the laboratory. Overexpression of the measles virus (MV receptor CD46 in many tumour cells may direct the virus to preferentially enter transformed cells and there is increasing awareness of the importance of nectin-4 and signaling lymphocytic activation molecule (SLAM in oncolysis. Successful attempts to retarget MV by inserting genes for tumour-specific ligands to antigens such as carcinoembryonic antigen (CEA, CD20, CD38, and by engineering the virus to express synthetic microRNA targeting sequences, and “blinding” the virus to the natural viral receptors are exciting measures to increase viral specificity and enhance the oncolytic effect. Sodium iodine symporter (NIS can also be expressed by MV, which enables in vivo tracking of MV infection. Radiovirotherapy using MV-NIS, chemo-virotherapy to convert prodrugs to their toxic metabolites, and immune-virotherapy including incorporating antibodies against immune checkpoint inhibitors can also increase the oncolytic potential. Anti-viral host immune responses are a recognized barrier to the success of MV, and approaches such as transporting MV to the tumour sites by carrier cells, are showing promise. MV Clinical trials are producing encouraging preliminary results in ovarian cancer, myeloma and cutaneous non-Hodgkin lymphoma, and the outcome of currently open trials in glioblastoma multiforme, mesothelioma and squamous cell carcinoma are eagerly anticipated.

  14. Effectiveness of a vaccination program against mumps in Ukraine.

    Hrynash, Y; Nadraga, A; Dasho, M

    2008-12-01

    Medical records and incidence data were analyzed retrospectively to document the epidemiology, clinical features, and outcomes of mumps in relation to vaccination status in the Lviv province of Ukraine over a 7.5-year period, beginning in 2000, when a second dose of mumps vaccine was introduced. Lviv, 1 of 27 provinces in western Ukraine, with a land area of 21,833 km(2), had a total population of about 2,555,834 in 2006. The initial success of the second dose introduction in 2000 in Ukraine was limited by a local outbreak of mumps in Lviv province in 2000-2002 due to a vaccine shortage; most cases were over the age of 7 years. The vaccine with the Leningrad-3 virus strain used before 2001 was then replaced by the triple vaccine "Priorix", with the RIT 4385 derivate of the Jeryl Lynn strain, Belgium. Orchitis and aseptic meningitis were associated with the Russian vaccine. Of the 10,894 reported cases, the most severe (367 cases, 3.4%) were hospitalized in the Lviv Hospital for Infectious Diseases. Admitted patients were predominantly male and over 14 years old. Of the 367 patients admitted to the Lviv Hospital for Infectious Diseases, 45.8% had been vaccinated (mostly by a first dose of Russian vaccine), 15.9% had not been vaccinated, and 38.1% had an unknown vaccination status. More mumps cases occurred in winter and spring than in summer and autumn. The clinical picture and complications (orchitis, pancreatitis, meningitis, and encephalitis) were typical of this disease. The vaccine shortage and an increase in the susceptible population among those who received the Russian vaccine contributed to the outbreak. The use of vaccine with a derivate of the Jeryl Lynn strain has resulted in a dramatic drop in mumps cases since 2002.

    The clinical features, chest radiographs and computed tomographic (CT) images were evaluated in 11 cases of serologically proved adult measles complicated with pneumonia (10 were previously healthy and one had sarcoidosis). Pneumonia appeared during the rash period in all cases. Respiratory symptoms were cough (9/11), dyspnea (3/11), and hypoxemia (10/11). Pneumonia manifestations were detected in only 4 cases by chest radiograph; on the other hand, they were seen in all cases by CT scan and consisted of ground-glass opacities (73%), nodular opacities (64%) and consolidation (27%). CT seems to be useful method to detect measles pneumonia if it is suspected. Measles pneumonia in previously healthy patients had a good prognosis, as the hypoxemia disappeared within 6 days in all cases. The sarcoidosis patient showed prolonged pneumonic shadows and period of hypoxemia. Measles pneumonia occurring in a host with cellular immunodeficiency may have a severe clinical course. (author)

  16. Acute measles encephalitis in partially vaccinated adults.

    Annette Fox

    Full Text Available The pathogenesis of acute measles encephalitis (AME is poorly understood. Treatment with immune-modulators is based on theories that post-infectious autoimmune responses cause demyelination. The clinical course and immunological parameters of AME were examined during an outbreak in Vietnam.Fifteen measles IgM-positive patients with confusion or Glasgow Coma Scale (GCS score below 13, and thirteen with uncomplicated measles were enrolled from 2008-2010. Standardized clinical exams were performed and blood collected for lymphocyte and measles- and auto-antibody analysis. The median age of AME patients was 21 years, similar to controls. Eleven reported receiving measles vaccination when aged one year. Confusion developed a median of 4 days after rash. Six patients had GCS <8 and four required mechanical ventilation. CSF showed pleocytosis (64% and proteinorrhachia (71% but measles virus RNA was not detected. MRI revealed bilateral lesions in the cerebellum and brain stem in some patients. Most received dexamethasone +/- IVIG within 4 days of admission but symptoms persisted for ≥3 weeks in five. The concentration of voltage gated calcium channel-complex-reactive antibodies was 900 pM in one patient, and declined to 609 pM ∼ 3 months later. Measles-reactive IgG antibody avidity was high in AME patients born after vaccine coverage exceeded 50% (∼ 25 years earlier. AME patients had low CD4 (218/µl, p = 0.029 and CD8 (200/µl, p = 0.012 T-cell counts compared to controls.Young adults presenting with AME in Vietnam reported a history of one prior measles immunization, and those aged <25 years had high measles-reactive IgG avidity indicative of prior vaccination. This suggests that one-dose measles immunization is not sufficient to prevent AME in young adults and reinforces the importance of maintaining high coverage with a two-dose measles immunization schedule. Treatment with corticosteroids and IVIG is common practice, and should be

    2015-08-01

    A discrete-time deterministic measles model with periodic transmission rate is formulated and studied. The basic reproduction number R0 is defined and used as the threshold parameter in determining the dynamics of the model. It is shown that the disease will die out if R0 1 . Parameters in the model are estimated on the basis of demographic and epidemiological data. Numerical simulations are presented to describe the seasonal fluctuation of measles infection in China.

    A sensitive radioimmunoassay (RIA) was introduced for detecting measles virus IgG and IgM antibodies. The hyperimmune response to the measles virus could be demonstrated more accurately by RIA than by haemagglutination inhibition (HI). The ratio between RIA and HI antibody titres was decidedly higher in sera and cerebrospinal fluids of patients with subacute sclerosing panencephalitis than in those of other groups tested. (author)

    2007-03-30

    To compare the incidence of aseptic meningitis associated with symptomatic natural mumps infection and in mumps vaccine recipients, we conducted a prospective comparative study. Consecutive samples of 1051 children with mumps were enrolled by 10 pediatricians and 21,465 vaccine recipients by 143 pediatric primary care practitioners, from January 1, 2000 to January 1, 2003. Parents used a daily diary to record symptoms during the period of illness (15 days) or 30-day period following immunization. Mumps infection was confirmed by virus isolation and/or detection of mumps virus genome in salivary and CSF samples. The incidence of aseptic meningitis was 13/1051 (1.24%) in patients with symptomatic natural mumps infection and was estimated to be 0.7-1.1% of overall infection in considering asymptomatic infection, and 10/21,465 (0.05%) in vaccine recipients. Although aseptic meningitis is a clear side effect of the mumps vaccine, the incidence is considerably lower than among those with symptomatic natural infection. Our results provide an informative data for consideration to resume mumps vaccine as a part of routine immunization schedule for Japanese children.

  20. Immunoglobulin GM and KM genes and measles vaccine-induced humoral immunity.

    Ovsyannikova, Inna G; Larrabee, Beth R; Schaid, Daniel J; Poland, Gregory A

    2017-10-04

    Identifying genetic polymorphisms that explain variations in humoral immunity to live measles virus vaccine is of great interest. Immunoglobulin GM (heavy chain) and KM (light chain) allotypes are genetic markers known to be associated with susceptibility to several infectious diseases. We assessed associations between GM and KM genotypes and measles vaccine humoral immunity (neutralizing antibody titers) in a combined cohort (n=1796) of racially diverse healthy individuals (age 18-41years). We did not discover any significant associations between GM and/or KM genotypes and measles vaccine-induced neutralizing antibody titers. African-American subjects had higher neutralizing antibody titers than Caucasians (1260mIU/mL vs. 740mIU/mL, p=7.10×10 -13 ), and those titers remained statistically significant (p=1.68×10 -09 ) after adjusting for age at enrollment and time since last vaccination. There were no statistically significant sex-specific differences in measles-induced neutralizing antibody titers in our study (p=0.375). Our data indicate a surprising lack of evidence for an association between GM and KM genotypes and measles-specific neutralizing antibody titers, despite the importance of these immune response genes.

    Full Text Available Clinical and epidemiological research on the evolution of measles in children in Leningrad – St. Petersburg from 1927–2014 with an analysis of the effectiveness of treatment of this infection. Divided into three periods of fighting «child plague». First period – to use in the practice of specific therapies and antibacterial drugs, characterized by high morbidity, severe weight, high rates of mortality. In the second period the use of donor serum syvotrotki convalescents and sulfa drugs significantly lowered the mortality rate due to the effective treatment of pneumococcal pneumonia. The use of penicillin and broad-spectrum antibiotics led to a further reduction in the severity of measles, a sharp decline in mortality – to tenths and hundredths of a percent. The third period is due to the mass of active immunization against measles, characterized by a significant decline in incidence rates up to her absence in some years. Combined therapy of children with measles in modern conditions with the inclusion etiotropic drugs (Viferon causes rapid regression of the symptoms of measles, warns layering respiratory viral infection contributes to the smooth course of the disease.

    Measles is a highly contagious viral infection. Measles transmission can be prevented through high population immunity (>or=95%) achieved by measles vaccination. In the Republic of the Marshall Islands (RMI), no measles cases were reported during 1989-2002; however, a large measles outbreak occurred in 2003. Reported 1-dose measles vaccine coverage among children aged 12-23 months varied widely (52-94%) between 1990 and 2000. RMI is a Pacific island nation (1999 population: 50,840). A measles case was defined as fever, rash, and cough, or coryza, or conjunctivitis, in an RMI resident between July 13 and November 7, 2003. A vaccination campaign was used for outbreak control. Of the 826 reported measles cases, 766 (92%) occurred in the capital (Majuro). There were 186 (23%) cases in infants aged or=15 years. The attack rate was highest among infants (Majuro atoll: 213 cases/1,000 infants). Among cases aged 1-14 years, 281 (59%) reported no measles vaccination before July 2003. There were 100 hospitalizations and 3 deaths. The measles H1 genotype was identified. The vaccination campaign resulted in 93% coverage among persons aged 6 months to 40 years. Interpretation Populations without endemic measles transmission can accumulate substantial susceptibility and be at risk for large outbreaks when measles virus is imported. 'Islands' of measles susceptibility may develop in infants, adults, and any groups with low vaccine coverage. To prevent outbreaks, high population immunity must be sustained by maintaining and documenting high vaccine coverage.

  5. Mumps prophylaxis in the light of a new test for antibody.

    Mortimer, P P

    1978-01-01

    A radial haemolysis test was used to investigate immunity to mumps. Antibody was found in 92 (42%) out of 220 children aged up to 5 years, 124 (78%) out of 159 children aged 6--10 years, 192 (86%) out of 222 children aged 11 years, 138 (92%) out of 150 children aged 15 years, and 280 (95%) out of 296 women attending an antenatal clinic. A group of 307 cadets aged 16--18 years were also tested and interviewed: 133 (95%) out of 140 who said that they had had mumps and 108 (87%) out of 124 who said that they had not had mumps were found to have antibody. The results suggest that tests for immunity to mumps by radial haemolysis would permit more rational use of mumps-specific immunoglobulin and attenuated mumps vaccine. PMID:365288

  6. Modified measles versus rubella versus atypical measles: One and same thing

    Surender Nikhil Gupta

    2015-01-01

    Full Text Available Introduction: In outbreak settings, more than one virus may be infecting the given population. In twin or triple outbreak of measles, German measles (rubella, and varicella in highly immunized hilly areas, maximal number of the case patients in all the hilly villages belonged to the older age group. It suggested an obvious shift to the higher age group, warranting second dose opportunity in such case scenario. The clinical presentations of viral diseases are too similar to differentiate. The aim is to clearly categorize the case patients of modified measles, rubella, and atypical measles in outbreak settings. Results: Four outbreaks are listed. In the first one, sixty case patients were identified from 1026 people in 5 villages. Of these, 41 were diagnosed by clinically, 8 were laboratory confirmed as measles and 11 were epidemiologically linked German measles case patients. Seventy percent of the cases were vaccinated for measles. In second case, we identified 29/35 measles and 6/35 were confirmed as epidemiologically linked unvaccinated chickenpox case patients. In third one, we identified 116 cases in eight villages (112/116 clinically and 04/116 laboratory confirmed. Majority of cases were immunized against measles, but only minor cases for rubella. In fourth case, we identified 505 case patients from mixed outbreaks of varicella, measles and rubella (30/505 clinically, 467/505 epidemiologically linked and 8/505 laboratory confirmed case patients from a study population of 3280. In all the four outbreaks, prima facie, the clinical presentations of both rubella and modified measles were difficult to differentiate. Discussion: On the basis of outbreak investigation and analytical inference, it has been observed that the symtomatology of modified measles and laboratory confirmed rubella case patients/epidemiologically linked cases are so similar placed that many a time, it becomes much difficult to line list the cases in one section of modified

    In developing countries, measles was a major cause of morbidity and mortality before the wide spread use of measles vaccine. The purpose of this study was to describe measles burden in an urban setting, Addis Ababa- since the implementation of measles case-based surveillance in Ethiopia. We analyzed measles surveillance data for 2004 -2014. Incidence of measles was described by sub city, by year and by age groups. Age specific incidence rate were calculated. Logistic regression was used to identify the predictors of confirmed measles cases. Of 4220 suspected measles cases 39% were confirmed cases. Males and females were equally affected. The mean affected age was 7.59 years. Measles cases peaked in 2010 and 2013-2014. Incidence of measles is higher among children less than five years old. Outer sub cities were more affected by measles in all years. Sub cities bordering with Oromia Regional State were more affected by measles. Older age groups were more affected than younger age groups (age ≤ five years old). Efforts to close immunity gaps against measles and further strengthen surveillance in urban settings, particularly among children below five years old, should be prioritized.

  11. Technical Aspects of Interfacing MUMPS to an External SQL Relational Database Management System

    Kuzmak, Peter M.; Walters, Richard F.; Penrod, Gail

    1988-01-01

    This paper describes an interface connecting InterSystems MUMPS (M/VX) to an external relational DBMS, the SYBASE Database Management System. The interface enables MUMPS to operate in a relational environment and gives the MUMPS language full access to a complete set of SQL commands. MUMPS generates SQL statements as ASCII text and sends them to the RDBMS. The RDBMS executes the statements and returns ASCII results to MUMPS. The interface suggests that the language features of MUMPS make it an attractive tool for use in the relational database environment. The approach described in this paper separates MUMPS from the relational database. Positioning the relational database outside of MUMPS promotes data sharing and permits a number of different options to be used for working with the data. Other languages like C, FORTRAN, and COBOL can access the RDBMS database. Advanced tools provided by the relational database vendor can also be used. SYBASE is an advanced high-performance transaction-oriented relational database management system for the VAX/VMS and UNIX operating systems. SYBASE is designed using a distributed open-systems architecture, and is relatively easy to interface with MUMPS.

  12. [Comparative evaluation of Leningrad-3 mumps vaccine virus neurovirulence in a neonatal rat model].

    Ignat'ev, G M; Otrashevskaia, E V; Rubin, S A

    2011-01-01

    The neurovirulence and replication potential of several mumps virus strains, including Leningrad-3 mumps vaccine virus (FSUE SIC "Microgen", Russia) and wild type strains isolated in the Novosibirsk Region (Russia), were assessed in rat tests. The mean neurovirulence scores of the Leningrad-3 virus (mumps vaccine strains (usually ranging from 0 to 5). In general, the relative ability of the viruses to replicate in the rat brain tracked with their neurovirulence scores. These results indicate a low neurovirulence potential of the Leningrad-3 mumps vaccine virus for humans.

    The fourth United Nations Millennium Development Goal, adopted in 2000, set a target to reduce child mortality by two thirds by 2015. One indicator of progress toward this target was measles vaccination coverage (1). In 2010, the World Health Assembly (WHA) set three milestones for measles control by 2015: 1) increase routine coverage with the first dose of a measles-containing vaccine (MCV1) among children aged 1 year to ≥90% at the national level and to ≥80% in every district; 2) reduce global annual measles incidence to measles mortality by 95% from the 2000 estimate (2).* In 2012, WHA endorsed the Global Vaccine Action Plan, † with the objective of eliminating measles in four World Health Organization (WHO) regions by 2015 and in five regions by 2020. Countries in all six WHO regions have adopted goals for measles elimination by or before 2020. Measles elimination is defined as the absence of endemic measles virus transmission in a region or other defined geographic area for ≥12 months, in the presence of a high quality surveillance system that meets targets of key performance indicators. This report updates a previous report (3) and describes progress toward global measles control milestones and regional measles elimination goals during 2000-2016. During this period, annual reported measles incidence decreased 87%, from 145 to 19 cases per million persons, and annual estimated measles deaths decreased 84%, from 550,100 to 89,780; measles vaccination prevented an estimated 20.4 million deaths. However, the 2015 milestones have not yet been met; only one WHO region has been verified as having eliminated measles. Improved implementation of elimination strategies by countries and their partners is needed, with focus on increasing vaccination coverage through substantial and sustained additional investments in health systems, strengthening surveillance systems, using surveillance data to drive programmatic actions, securing political commitment, and raising

    Chronic obstructive pulmonary disease (COPD) has potential origins in childhood but an association between childhood measles and post-bronchodilator (BD) airflow obstruction (AO) has not yet been shown. We investigated whether childhood measles contributed to post-BD AO through interactions with asthma and/or smoking in a non-immunized middle-aged population. The population-based Tasmanian Longitudinal Health Study (TAHS) cohort born in 1961 (n = 8583) underwent spirometry in 1968 before immunization was introduced. A history of childhood measles infection was obtained from school medical records. During the fifth decade follow-up (n = 5729 responses), a subgroup underwent further lung function measurements (n = 1389). Relevant main associations and interactions by asthma and/or smoking on post-BD forced expiratory volume in 1 s/forced vital capacity (FEV 1 /FVC; continuous variable) and AO (FEV 1 /FVC childhood measles. Childhood measles augmented the combined adverse effect of current clinical asthma and smoking at least 10 pack-years on post-BD FEV 1 /FVC ratio in middle age (z-score: -0.70 (95% CI: -1.1 to -0.3) vs -1.36 (-1.6 to -1.1), three-way interaction: P = 0.009), especially for those with childhood-onset asthma. For never- and ever-smokers of childhood measles, paradoxically, the odds for post-BD AO was not significant in the presence of childhood measles (OR: 12.0 (95% CI: 3.4-42) vs 2.17 (0.9-5.3)). Childhood measles infection appears to compound the associations between smoking, current asthma and post-BD AO. Differences between asthma subgroups provide further insight into the complex aetiology of obstructive lung diseases for middle-aged adults. © 2018 Asian Pacific Society of Respirology.

    Background: Mumps, a communicable, acute and previously well-controlled disease, has had recent and occasional resurgences in some areas. Methods: A randomized, double-blind, controlled and multistep phase I study of an F-genotype attenuated mumps vaccine produced in human diploid cells was conducted. A total of 300 subjects were enrolled and divided into 4 age groups: 16–60 years, 5–16 years, 2–5 years and 8–24 months. The groups were immunized with one injection per subject. Three different doses of the F-genotype attenuated mumps vaccine, A (3.5 ± 0.25 logCCID50), B (4.25 ± 0.25 logCCID50) and C (5.0 ± 0.25 logCCID50), as well as a placebo control and a positive control of a licensed A-genotype vaccine (S79 strain) were used. The safety and immunogenicity of this vaccine were compared with those of the controls. Results: The safety evaluation suggested that mild adverse reactions were observed in all groups. No serious adverse event (SAE) was reported throughout the trial. The immunogenicity test showed a similar seroconversion rate of the neutralizing and ELISA antibody in the 2- to 5-year-old and 8- to 24-month-old groups compared with the seroconversion rate in the positive control. The GMT of the neutralizing anti-F-genotype virus antibodies in the vaccine groups was slightly higher than that in the positive control group. Conclusions: The F-genotype attenuated mumps vaccine evaluated in this clinical trial was demonstrated to be safe and have effective immunogenicity vs. control. PMID:24614759

  6. Lack of association between measles virus vaccine and autism with enteropathy: a case-control study.

    Mady Hornig

    2008-09-01

    Full Text Available The presence of measles virus (MV RNA in bowel tissue from children with autism spectrum disorders (ASD and gastrointestinal (GI disturbances was reported in 1998. Subsequent investigations found no associations between MV exposure and ASD but did not test for the presence of MV RNA in bowel or focus on children with ASD and GI disturbances. Failure to replicate the original study design may contribute to continued public concern with respect to the safety of the measles, mumps, and rubella (MMR vaccine.The objective of this case-control study was to determine whether children with GI disturbances and autism are more likely than children with GI disturbances alone to have MV RNA and/or inflammation in bowel tissues and if autism and/or GI episode onset relate temporally to receipt of MMR. The sample was an age-matched group of US children undergoing clinically-indicated ileocolonoscopy. Ileal and cecal tissues from 25 children with autism and GI disturbances and 13 children with GI disturbances alone (controls were evaluated by real-time reverse transcription (RT-PCR for presence of MV RNA in three laboratories blinded to diagnosis, including one wherein the original findings suggesting a link between MV and ASD were reported. The temporal order of onset of GI episodes and autism relative to timing of MMR administration was examined. We found no differences between case and control groups in the presence of MV RNA in ileum and cecum. Results were consistent across the three laboratory sites. GI symptom and autism onset were unrelated to MMR timing. Eighty-eight percent of ASD cases had behavioral regression.This study provides strong evidence against association of autism with persistent MV RNA in the GI tract or MMR exposure. Autism with GI disturbances is associated with elevated rates of regression in language or other skills and may represent an endophenotype distinct from other ASD.

    Although the mumps vaccine has not been included in the national immunization program (NIP) in Japan, it has been shown that a two-dose routine vaccine program would be highly cost-effective. In this study, we carried outa questionnaire-based study to investigate how many Japanese parents want the mumps vaccine to be included in the NIP with proper information. The questionnaire was given to parents who visited the Pediatrics or neonatal intensive care unit of Nara Prefecture General Medical Center, Nara City, Japan, between 1 March 2017 and 31 August 2017. The questionnaire consisted of information about mumps and six questions, for example (i) do parents know that mumps can be prevented by vaccine; (ii) do they know that they need to pay for mumps vaccines; and (iii) do they hope that the government will resume routine mumps vaccination. In total, 1,224 parents answered the questionnaire. A total of 81% and 75.4% of parents knew that mumps can be prevented by vaccination and that mumps vaccine is not included in the NIP, respectively, before reading the information. After reading the information, 95.0% of parents thought that mumps vaccine should be included in the NIP. While 61.7% of parents answered that they would choose two-dose vaccination without governmental financial support, 92.1% of them would choose two-dose vaccination with governmental financial support (P mumps vaccine to be included in the NIP. Japan is able to start routine use of the mumps vaccine now. © 2017 Japan Pediatric Society.

  8. Patterns of measles transmission among airplane travelers.

    Edelson, Paul J

    2012-09-01

    With advanced air handling systems on modern aircraft and the high level of measles immunity in many countries, measles infection in air travelers may be considered a low-risk event. However, introduction of measles into countries where transmission has been controlled or eliminated can have substantial consequences both for the use of public health resources and for those still susceptible. In an effort to balance the relatively low likelihood of disease transmission among largely immune travelers and the risk to the public health of the occurrence of secondary cases resulting from importations, criteria in the United States for contact investigations for measles exposures consider contacts to be those passengers who are seated within 2 rows of the index case. However, recent work has shown that cabin air flow may not be as reliable a barrier to the spread of measles virus as previously believed. Along with these new studies, several reports have described measles developing after travel in passengers seated some distance from the index case. To understand better the potential for measles virus to spread on an airplane, reports of apparent secondary cases occurring in co-travelers of passengers with infectious cases of measles were reviewed. Medline™ was searched for articles in all languages from 1946 to week 1 of March 2012, using the search terms "measles [human] or rubeola" and ("aircraft" or "airplane" or "aeroplane" or "aviation" or "travel" or "traveler" or "traveller"); 45 citations were returned. Embase™ was searched from 1988 to week 11 2012, using the same search strategy; 95 citations were returned. Papers were included in this review if they reported secondary cases of measles occurring in persons traveling on an airplane on which a person or persons with measles also flew, and which included the seating location of both the index case(s) and the secondary case(s) on the plane. Nine reports, including 13 index cases and 23 apparent secondary cases

  9. The potential for measles transmission in England

    Fraser Graham

    2008-09-01

    Full Text Available Abstract Background Since the schools vaccination campaign in 1994, measles has been eliminated from England. Maintaining elimination requires low susceptibility levels to keep the effective reproduction number R below 1. Since 1995, however, MMR coverage in two year old children has decreased by more than 10%. Methods Quarterly MMR coverage data for children aged two and five years resident in each district health authority in England were used to estimate susceptibility to measles by age. The effective reproduction numbers for each district and strategic health authority were calculated and possible outbreak sizes estimated. Results In 2004/05, about 1.9 million school children and 300,000 pre-school children were recorded as incompletely vaccinated against measles in England, including more than 800,000 children completely unvaccinated. Based on this, approximately 1.3 million children aged 2–17 years were susceptible to measles. In 14 of the 99 districts, the level of susceptibility is sufficiently high for R to exceed 1, indicating the potential for sustained measles transmission. Eleven of these districts are in London. Our model suggests that the potential exists for an outbreak of up to 100,000 cases. These results are sensitive to the accuracy of reported vaccination coverage data. Conclusion Our analysis identified several districts with the potential for sustaining measles transmission. Many London areas remain at high risk even allowing for considerable under-reporting of coverage. Primary care trusts should ensure that accurate systems are in place to identify unimmunised children and to offer catch-up immunisation for those not up to date for MMR.

  10. Measles Case Fatality Rate in Bihar, India, 2011–12

    2014-01-01

    Background Updated estimates of measles case fatality rates (CFR) are critical for monitoring progress towards measles elimination goals. India accounted for 36% of total measles deaths occurred globally in 2011. We conducted a retrospective cohort study to estimate measles CFR and identify the risk factors for measles death in Bihar–one of the north Indian states historically known for its low vaccination coverage. Methods We systematically selected 16 of the 31 laboratory-confirmed measles outbreaks occurring in Bihar during 1 October 2011 to 30 April 2012. All households of the villages/urban localities affected by these outbreaks were visited to identify measles cases and deaths. We calculated CFR and used multivariate analysis to identify risk factors for measles death. Results The survey found 3670 measles cases and 28 deaths (CFR: 0.78, 95% confidence interval: 0.47–1.30). CFR was higher among under-five children (1.22%) and children belonging to scheduled castes/tribes (SC/ST, 1.72%). On multivariate analysis, independent risk factors associated with measles death were age Measles CFR in Bihar was low. To further reduce case fatality, health authorities need to ensure that SC/ST are targeted by the immunization programme and that outbreak investigations target for vitamin A treatment of cases in high risk groups such as SC/ST and young children and ensure regular visits by health-workers in affected villages to administer vitamin A to new cases.

  12. Measles, immune suppression and vaccination: direct and indirect nonspecific vaccine benefits.

    Mina, Michael J

    2017-06-01

    The measles virus is among the most transmissible viruses known to infect humans. Prior to measles vaccination programs, measles infected over 95% of all children and was responsible for over 4 million deaths each year. Measles vaccination programs have been among the greatest public health achievements reducing, eliminating endemic measles in the whole of the Americas and across much of the globe. Where measles vaccines are introduced, unexpectedly large reductions in all-cause childhood mortality have been observed. These gains appear to derive in part from direct heterologous benefits of measles vaccines that enhance innate and adaptive immune responses. Additionally, by preventing measles infections, vaccination prevents measles-associated short- and long-term immunomodulating effects. Before vaccination, these invisible hallmarks of measles infections increased vulnerability to non-measles infections in nearly all children for weeks, months, or years following acute infections. By depleting measles incidence, vaccination has had important indirect benefits to reduce non-measles mortality. Delineating the relative importance of these two modes of survival benefits following measles vaccine introduction is of critical public health importance. While both support continued unwavering global commitments to measles vaccination programs until measles eradication is complete, direct heterologous benefits of measles vaccination further support continued commitment to measles vaccination programs indefinitely. We discuss what is known about direct and indirect nonspecific measles vaccine benefits, and their implications for continued measles vaccination programs. © 2017 The British Infection Association.

    2010-12-01

    Mumps epidemics are usually caused by airborne transmission of mumps virus (MuV) and have high morbidity in non-immunized children. Epidemiological studies in many regions of China show that the genotype F viral strain is the most prevalent. However, the genotype A strain is currently used to prepare vaccines. Regional epidemiological MuV data suggest a significant application for the development of live attenuated mumps vaccines targeting specific genotypes. This article reports the isolation and culture of a genotype F MuV candidate strain that could be used to prepare a live attenuated mumps vaccine. This strain is shown to have good immunological efficacy and stability in neurovirulence evaluations. This work should facilitate the implementation of mumps vaccination in mainland China by targeting the most prevalent MuV genotype, genotype F. Copyright © 2010 Institut Pasteur.

  14. Emergent lineages of mumps virus suggest the need for a polyvalent vaccine

    Meghan May

    2018-01-01

    Full Text Available Mumps outbreaks among vaccinated patients have become increasingly common in recent years. While there are multiple conditions driving this re-emergence, convention has suggested that these outbreaks are associated with waning immunity rather than vaccine escape. Molecular evidence from both the ongoing American and Dutch outbreaks in conjunction with recent structural biology studies challenge this convention, and suggest that emergent lineages of mumps virus exhibit key differences in antigenic epitopes from the vaccine strain employed: Jeryl-Lynn 5. The American and Dutch 2016–2017 outbreak lineages were examined using computational biology through the lens of diversity in immunogenic epitopes. Findings are discussed and the laboratory evidence indicating neutralization of heterologous mumps strains by serum from vaccinated individuals is reviewed. Taken together, it is concluded that the number of heterologous epitopes occurring in mumps virus in conjunction with waning immunity is facilitating small outbreaks in vaccinated patients, and that consideration of a polyvalent mumps vaccine is warranted.

    Because methods for measuring cell-mediated immunity (CMI) to the mumps virus are expensive, time-consuming, and technically demanding, the role of CMI in mumps virus infection remains unclear. To address this issue, we report here the development of a simplified method for measuring mumps virus-specific CMI that is suitable for use in diverse laboratory and clinical settings. A mumps vaccine was cultured with whole blood, and interferon (IFN)-γ released into the culture supernatant was measured using an enzyme-linked immunosorbent assay. IFN-γ production in blood from vaccinated subjects markedly increased in response to the vaccine and decreased before the antibody titer decreased in some cases, suggesting that this assay may be used as a simple surrogate method for measuring CMI specific for the mumps virus.

    2012-01-01

    Full text: A 36-years-old woman was admitted in a Clinic of Neurology due to emergency presented with acute onset of altered mental status, tonic-clonic convulsions in four extremities, bladder and bowel dysfunction. This attack lasted for 2-3 minutes.The neurological investigation showed lesion of n.facialis and n.hypoglossus on the right side from central origin, right hemiparesis, positive pathologic reflex Babinski on the right side, partial sensor and motor aphasia. An analysis of the cerebrospinal fluid (CSF) showed increased levels of protein - 2.15 g/l. A week before admission to the hospital the patient had been discharged from an Infectious ward, where Measles had been diagnosed.The diagnosis was verified also with the presence of specific IgM in serum. Magnetic resonance tomography: Supratentorial on the T2W and more visibly on the FLAIR images were seen relatively homogenous high signal foci, affecting the left putamen, partially the hind limb of the left internal capsule, the body of the left nucleus caudatis, as well as more diffuse changes, affecting the cortex and subcortex in the stroke area, the upper and partially the left medial temporal gyrus. On the T1W images the changes were low signal ones. Small-degree compression of the cella media of the left lateral ventricle was noted in the changes, affecting nucleus caudatus. Infratentorial: No signal changes, affecting the cerebral stem, the small brain structures, the pontocerebral angles and the internal auditory canals were observed. Conclusion: The finding corresponds to areas of demielinization, edema and gliosis with the localization described with possible infectious genesis (encephalitis)

    Full Text Available Background & objectives: The reports from the countries where mumps vaccine is given as routine immunization suggest differences in mumps virus neutralizing antibody titres when tested with vaccine and wild type viruses. Such reports are unavailable from countries like India where mumps vaccine is not included in routine immunization. We, therefore, undertook this study to understand the cross-neutralization activity of Indian mumps viruses. Methods: By using commercial mumps IgG enzyme immunoassay (EIA and a rapid focus reduction neutralization test (FRNT, a panel of serum samples was tested. The panel consisted of 14 acute and 14 convalescent serum samples collected during a mumps outbreak and 18 archived serum samples. Two wild types (genotypes C and G and Leningrad-Zagreb vaccine strain (genotype N were used for the challenge experiments and FRNT titres were determined and further compared. The HN protein sequence of three mumps viruses was analyzed for the presence of key epitopes. Results: All serum samples effectively neutralized mumps virus wild types and a vaccine strain. However, significantly lower FRNT titres were noted to wild types than to vaccine strain (P<0.05. The comparison between EIA and FRNT results revealed 95.6 per cent agreement. No amino acid changes were seen in the epitopes in the Indian wild type strains. All potential N-linked glycosylation sites were observed in Indian strains. Interpretation & conclusions:Good cross-neutralization activity was observed for three mumps virus strains, however, higher level of FRNT titres was detected for mumps virus vaccine strain compared to Indian wild type isolates.

  18. Mumps-containing vaccine effectiveness during outbreaks in two schools in Guangdong, China, 2012

    2012-12-01

    Full Text Available Introduction: Mumps-containing vaccine was licensed in the 1990s in China with a single dose administered routinely to children aged 18–24 months since 2008. However, an increase in reported mumps cases during the period 2009 to 2012 casts doubt on the effectiveness of a single-dose mumps vaccination. In March 2012, large numbers of mumps cases in a day-care centre and primary school in Guangdong Province were investigated to estimate the effectiveness of mumps-containing vaccine.Methods: A mumps case was defined as a case with acute onset of unilateral or bilateral swelling of the parotid gland or other salivary glands. Clinical data were collected among students and staff members in the two schools from 6 February to 3 June 2012. Vaccination history was obtained from immunization certificates. Vaccine effectiveness (VE was calculated among children in classes that had more than two mumps cases.Results: The cohort included 369 children from seven classes, four from the day-care centre and three from the primary school. Vaccination certificates available for 347 children showed immunization coverage of 82% (285/347. The overall attack rate was 14.6% (54/369; the VE for a single dose of mumps vaccine was 65% (95% confidence interval [CI]: 19%–85% when given within three years and 15% (95% CI: -2%–52% when given three to six years before the outbreak. For two doses of vaccine the VE was 53% (95% CI: -15–80%.Discussion: A single dose of mumps-containing vaccine was not effective to prevent these outbreaks among preschool and schoolchildren. A second dose of mumps-containing vaccine to four to five-year-old children should be considered in China.

    Mumps is a common childhood viral disease characterized by fever and swelling of the parotid gland. The prognosis is generally good, although some complications, such as encephalitis (0.1%), exist. Acute encephalopathy with biphasic seizures and late reduced diffusion is the most common type of acute encephalopathy. However, this type of encephalopathy has not been reported in association with mumps infection. A previously healthy 3-year-old Japanese boy had a brief convulsion after fever for 3days, and then had conscious disturbance and parotitis. After several days, he had a second brief convulsion and was admitted. Increased serum amylase levels and presence of anti-mumps immunoglobulin M antibody confirmed mumps parotitis. The patient had another brief seizure later the day of admission. He did not have status or cluster seizures, although the biphasic nature of his seizures, conscious disturbance between the seizures, no pleocytosis in cerebrospinal fluid, and brain magnetic resonance images were consistent with acute encephalopathy with biphasic seizures and late reduced diffusion. In Japan, the mumps vaccine is not administered as a part of routine immunizations. It thus has low coverage (30-40%), and as a result, mumps infections are still common. However, this is the first case of mumps-related acute encephalopathy with biphasic seizures and late reduced diffusion. This case may be representative of only a minority of patients with mumps-associated central nervous system involvement. Nevertheless, this diagnostic possibility may be considered. In order to prevent mumps-related complications, routine mumps vaccination might be warranted. Copyright © 2017 The Japanese Society of Child Neurology. Published by Elsevier B.V.

    2003-01-01

    Full Text Available OBJECTIVE: To describe the frequency of lymphocytic meningitis(LM concomitant with mumps, before and after the mumps mass immunization campaign in 1997. METHOD: Demographic, clinical and cerebrospinal fluid(CSF information was collected from the chart of all patients aged from 2 to 59 months, whose CSF exam was performed at the CSF Lab/FJS, between 1989 and 2001. LM was defined as pleocytosis composed by lymphomononuclear cells and negative exams for bacterial or mycologic infection. RESULTS: Of 1,519 patients, 894(58.9% had normal exams. LM was present in 301(19.8% patients, out of which 22(7.3% had concomitant mumps. The frequency of LM ranged from 15.8% in 1989 to 19.7% in 2001 and of LM with concomitant Mumps ranged from 10.5% in 1989 to 4.7% in 1995, when the last cases were registered. CONCLUSION: It is probable that the mumps vaccine campaign has influenced the absence of LM with concomitant Mumps, from 1996 to 2001.

    Measles, caused by the Morbilli virus, is a highly (about 95 %) contagious disease affecting primarily children, but without proper immunisation, adults can also be infected. The leading symptoms of the disease are high fever that presents after an incubation period of 9-10 days and the red rash that begins several days after the fever starts. Beyond specific generalized symptoms, measles may have ocular symptoms. The most commonly occurring conjunctivitis, the so-called "red eye symptom", is not characteristic only for measles infection, however, by taking the generalized symptoms it can suggest the diagnosis at the beginning of the disease. Conjunctivitis of varying severity is noticed in the half of the cases without using ophthalmological instrumentation. Using ophthalmological instrumentation, the mild forms of conjunctivitis can be diagnosed, by meticulous ophthalmological examination, further eye diseases can be discovered. The viral conjunctivitis can progress to keratitis and bacterial superinfection can occur. If the infection presents in childhood it can affect the posterior segment. The fight against measles is very effective in Hungary since the vaccination has been introduced, and the lack of vaccination is also the primary cause of the risk to the disease. In the diagnosis, symptomatic treatment of the disease and the curbing of possible mass infections, the practicing physician (general practitioner) has a key role. The correct care of the infected patient in Hungary is provided by a methodological letter, professional information and legal guides. Orv Hetil. 2017; 158(39): 1523-1527.

  2. Measles Outbreak among Unvaccinated Children in Bajura

    S Sitaula

    2010-12-01

    CFR of this outbreak is higher than the national CFR. Vaccine efficacy of 50% points towards the need for investigation of vaccine logistics and cold chain system. Moreover, this laboratory test confirmed an outbreak showing that the measles virus could be imported from an endemic region and rapidly spread through a susceptible population who were previously not immunized.

  3. Measles vaccination using a microneedle patch☆

    Measles vaccination programs would benefit from delivery methods that decrease cost, simplify logistics, and increase safety. Conventional subcutaneous injection is limited by the need for skilled healthcare professionals to reconstitute and administer injections, and by the need for safe needle handling and disposal to reduce the risk of disease transmission through needle re-use and needlestick injury. Microneedles are micron-scale, solid needles coated with a dry formulation of vaccine that dissolves in the skin within minutes after patch application. By avoiding the use of hypodermic needles, vaccination using a microneedle patch could be carried out by minimally trained personnel with reduced risk of blood-borne disease transmission. The goal of this study was to evaluate measles vaccination using a microneedle patch to address some of the limitations of subcutaneous injection. Viability of vaccine virus dried onto a microneedle patch was stabilized by incorporation of the sugar, trehalose, and loss of viral titer was less than 1 log10(TCID50) after storage for at least 30 days at room temperature. Microneedle patches were then used to immunize cotton rats with the Edmonston-Zagreb measles vaccine strain. Vaccination using microneedles at doses equaling the standard human dose or one-fifth the human dose generated neutralizing antibody levels equivalent to those of a subcutaneous immunization at the same dose. These results show that measles vaccine can be stabilized on microneedles and that vaccine efficiently reconstitutes in vivo to generate a neutralizing antibody response equivalent to that generated by subcutaneous injection.

  4. Antibody neutralization of retargeted measles viruses

    2014-01-01

    The measles virus (MV) vaccine lineage is a promising oncolytic but prior exposure to the measles vaccine or wild-type MV strains limits treatment utility due to the presence of anti-measles antibodies. MV entry can be redirected by displaying a polypeptide ligand on the Hemagglutinin (H) C-terminus. We hypothesized that retargeted MV would escape neutralization by monoclonal antibodies (mAbs) recognizing the H receptor-binding surface and be less susceptible to neutralization by human antisera. Using chimeric H proteins, with and without mutations that ablate MV receptor binding, we show that retargeted MVs escape mAbs that target the H receptor-binding surface by virtue of mutations that ablate infection via SLAM and CD46. However, C-terminally displayed domains do not mediate virus entry in the presence of human antibodies that bind to the underlying H domain. In conclusion, utility of retargeted oncolytic measles viruses does not extend to evasion of human serum neutralization. PMID:24725950

  5. Measles Virus Fusion Protein: Structure, Function and Inhibition

    Philippe Plattet

    2016-04-01

    Full Text Available Measles virus (MeV, a highly contagious member of the Paramyxoviridae family, causes measles in humans. The Paramyxoviridae family of negative single-stranded enveloped viruses includes several important human and animal pathogens, with MeV causing approximately 120,000 deaths annually. MeV and canine distemper virus (CDV-mediated diseases can be prevented by vaccination. However, sub-optimal vaccine delivery continues to foster MeV outbreaks. Post-exposure prophylaxis with antivirals has been proposed as a novel strategy to complement vaccination programs by filling herd immunity gaps. Recent research has shown that membrane fusion induced by the morbillivirus glycoproteins is the first critical step for viral entry and infection, and determines cell pathology and disease outcome. Our molecular understanding of morbillivirus-associated membrane fusion has greatly progressed towards the feasibility to control this process by treating the fusion glycoprotein with inhibitory molecules. Current approaches to develop anti-membrane fusion drugs and our knowledge on drug resistance mechanisms strongly suggest that combined therapies will be a prerequisite. Thus, discovery of additional anti-fusion and/or anti-attachment protein small-molecule compounds may eventually translate into realistic therapeutic options.

    The mumps outbreak in the Plzeň Region in 2011 was analysed retrospectively using the epidemiological, clinical, and laboratory data. Vaccine efficacy analysis was also conducted in various population groups. The routine procedure and standard form were used by the epidemiologists to collect data on the age, sex, place of residence, presence in collectivities, date of disease onset, type of complications and date of their onset, hospital admission, vaccination, and results of laboratory analyses. Based on the records of general practitioners for children and adolescents, data on the vaccination of children born in the previous three years have been provided to the epidemic control departments every year by 30 June since 1989. To estimate the vaccination coverage rate, the numbers of single-dose or two-dose recipients are related to the number of children registered in a given year. The first year of vaccine recipients were children born in 1986 who were aged 25 in 2011. The data collected on the population of the Plzeň Region were used for the primary analyses. To estimate the efficacy of the mumps vaccine, age and vaccine coverage cohort analysis was performed using the screening method. To analyse categories, the chi-square test with Yates correction was applied at a significance level of p = 0.05 % (EPIINFO version 6.04d). In 2011, 721 mumps cases were reported in the Plzeň Region (incidence: 126.1 cases per 100 000 population). The average patient age was 19.4 years, with a median of 18 years (age range 1-77 years). Four hundred and seventeen (57.8%) patients were males. Biological specimens from 375 (52.0%) patients were investigated serologically in the virology laboratory and mumps were laboratory confirmed in 316 (43.8%) of them - in 222 patients, one blood specimen was analysed. The most afflicted area was the Klatovy district with the incidence of 449.3/100 000 population. The most affected age group were 15-19 year-olds with the incidence of 1008

    Measles outbreaks are reported after insufficient vaccine coverage, especially in countries recovering from natural disaster or conflict. We compared seroprevalence to measles in blood donors in Rwanda and Sweden and explored distribution of active cases of measles and vaccine coverage in Rwanda. 516 Rwandan and 215 Swedish blood donors were assayed for measles-specific immunoglobulin G (IgG) by enzyme-linked immunosorbent assay (ELISA). Data on vaccine coverage and acute cases in Rwanda from 1980 to 2014 were collected, and IgM on serum samples and polymerase chain reaction (PCR) on nasopharyngeal (NPH) swabs from suspected measles cases during 2010-2011 were analysed. The seroprevalence of measles IgG was significantly higher in Swedish blood donors (92.6%; 95% CI: 89.1-96.1%) compared to Rwandan subjects (71.5%; 95% CI: 67.6-75.4%) and more pronounced Rwanda, with the exception of an outbreak in 1995 following the 1994 genocide. 76/544 serum samples were IgM positive and 21/31 NPH swabs were PCR positive for measles, determined by sequencing to be of genotype B3. Measles seroprevalence was lower in Rwandan blood donors compared to Swedish subjects. Despite this, the number of reported measles cases in Rwanda rapidly decreased during the study period, concomitant with increased vaccine coverage. Taken together, the circulation of measles was limited in Rwanda and vaccine coverage was favourable, but seroprevalence and IgG levels were low especially in younger age groups.

    Full Text Available Abstract Background In the Czech Republic, two-dose immunization against mumps achieves 98 % coverage. The routine reporting detects mumps cases, clinical complications, and hospital admissions in unvaccinated but also in vaccinated individuals. Using surveillance data of patients with mumps we assessed the effectiveness of mumps vaccination on mumps clinical complications and hospitalization need. We also investigated the effect of the time since immunization. Methods We analysed data on incident mumps cases reported to the Czech national surveillance system in 2007–2012. Using a logistic regression model with adjustment for age, sex, year of onset, and the administrative region, the association between vaccination and the most frequent mumps complications and hospitalization was evaluated. The adjusted odds ratios (ORa for mumps complications were compared between the vaccinated and non-vaccinated groups, reflecting the vaccine effectiveness (VEa computed as VEa = (1-ORa×100. We estimated the risk of mumps complications by the time from vaccination. Results From total of 9663 mumps analysed cases 5600 (58 % occurred in males. The mean age at the disease onset was 17.3, median 16 years. Ninety percent of the study patients had no complications, while 1.6 % developed meningitis, 0.2 % encephalitis, and 0.6 % pancreatitis. Mumps orchitis occurred in 659 (11.8 % male cases. In total, 1192 (12.3 % patients required hospitalization. Two doses of vaccine received by 81.8 % cases significantly reduced the risk of hospitalization: ORa 0.29 (95 % CI: 0.24, 0.35. Two doses showed statistically significant VEa 64 % (95 % CI: 46, 79 for meningitis, 93 % (95 % CI: 66, 98 for encephalitis in all cases, and 72 % (95 % CI: 64, 78 for orchitis in males. Vaccine effectiveness for orchitis declined from 81 to 74 % and 56 % in the most affected age groups 10–14, 15–19, and 20–24 years, respectively. Among 7850 two-dose recipients

    Mumps is a vaccine-preventable disease candidate for elimination. Positive predictive value (PPV) of clinical case definition was assessed. During 2007, 410 suspected cases were reported in Catalonia: 348 fulfilled clinical case definition and 159 were laboratory confirmed. Incidence rate was 4.8 per 100,000 for cases that fulfilled the clinical definition, and 2.2 for laboratory confirmed cases. Global PPV was 44.5%; 38.5% in or =15 years (p=0.04). Most laboratory confirmed cases (72.3%) received at least one MMR dose. With sustained high MMR coverage, laboratory confirmation is necessary to control the disease and assess vaccine failure.

  10. Perspective on Global Measles Epidemiology and Control and the Role of Novel Vaccination Strategies

    Melissa M. Coughlin

    2017-01-01

    Full Text Available Measles is a highly contagious, vaccine preventable disease. Measles results in a systemic illness which causes profound immunosuppression often leading to severe complications. In 2010, the World Health Assembly declared that measles can and should be eradicated. Measles has been eliminated in the Region of the Americas, and the remaining five regions of the World Health Organization (WHO have adopted measles elimination goals. Significant progress has been made through increased global coverage of first and second doses of measles-containing vaccine, leading to a decrease in global incidence of measles, and through improved case based surveillance supported by the WHO Global Measles and Rubella Laboratory Network. Improved vaccine delivery methods will likely play an important role in achieving measles elimination goals as these delivery methods circumvent many of the logistic issues associated with subcutaneous injection. This review highlights the status of global measles epidemiology, novel measles vaccination strategies, and describes the pathway toward measles elimination.

    2013-03-01

    Measles cases in the European Region have been increasing in the last decade; this illustrates the challenge of what we are now encountering in the form of pediatric preventable diseases. In Catalonia, autochthonous measles was declared eliminated in the year 2000 as the result of high measles-mumps-rubella vaccine (MMR) coverage for first and second dose (15 mo and 4 y) since the mid-1990s. From then on, sporadic imported cases and small outbreaks appeared, until in 2006-2007 a large measles outbreak affecting mostly unvaccinated toddlers hit the Barcelona Health Region. Consequently, in January 2008, first dose administration of MMR was lowered from 15 to 12 mo of age. A new honeymoon period went by until the end of 2010, when several importations of cases triggered new sustained transmission of different wild measles virus genotypes, but this time striking young adults. The aim of this study is to show the effect of a change in MMR vaccination schedule policy, and the difference in age incidence and hospitalization rates of affected individuals between both outbreaks.   Epidemiologic data were obtained by case interviews and review of medical records. Samples for virological confirmation and genotyping of cases were collected as established in the Measles Elimination plan guidelines. Incidence rate (IR), rate ratio (RR) and their 95% CI and hospitalization rate (HR) by age group were determined. Statistic z was used for comparing proportions. Total number of confirmed cases was 305 in the 2010 outbreak and 381 in the 2006-2007 outbreak; mean age 20 y (SD 14.8 y; 3 mo to 51 y) vs. 15 mo (SD 13.1 y; 1 mo to 50 y). Highest proportion of cases was set in ≥ 25 y (47%) vs. 24.2% in 2006 (p < 0.001). Differences in IR for ≤ 15 mo (49/100,000 vs. 278.2/100,000; RR: 3,9; 95%CI 2,9-5.4) and in overall HR 29.8% vs. 15.7% were all statistically significant (p < 0.001). The change of the month of age for the administration of the first MMR dose proved successful to

    The epidemiologic and genetic characteristics of mumps viruses detected in China from 1995 to 2010 were analyzed in this study. Mumps remains endemic in China with a high overall incidence rate. The incidence of mumps in Western China was higher than that in other regions of the country. Each year, most of mumps cases occurred between April and July, but a small peak also occurred in November and December. Mumps cases primarily affected the under 15 year old age group. Virologic data demonstrated that genotype F was the predominant circulating genotype throughout China for at least 15 years and no other genotype was detected between 1995 and 2010. Analysis of sequence data from the small hydrophobic (SH) gene indicated that multiple transmission chains of genotype F were found in various provinces of China, with no apparent chronologic and geographic restriction. This is the first report describing the epidemiology of mumps and genetic characterization of mumps viruses at the national level in China. Copyright © 2013 Elsevier B.V. All rights reserved.

    2009-10-05

    To describe a prolonged outbreak of mumps in the Kimberley region of Western Australia in 2007-2008. Descriptive analysis of all mumps cases notified to the WA Notifiable Infectious Diseases Database for the period 1 July 2007 to 30 June 2008. Notified cases of mumps by patients' place of residence, age, Indigenous or non-Indigenous ethnicity, vaccination status and method of diagnosis. 84% (153/183) of mumps notifications in WA over the study period occurred in the Kimberley region or were directly linked to Kimberley cases. Median age of patients was 18 years (range, 2-63 years), and 54% of patients were aged less than 20 years. Almost all (92%) were Australian Aboriginal people; 67% (102/153) had received at least one dose of mumps vaccine, and 52% had received two doses. The highest notification rate (1816 cases per 100,000 population) was in the Aboriginal 15-19-years age group, and 92% of these patients had received at least one dose of mumps vaccine. Almost all outbreak cases (94%) were laboratory confirmed. Genotyping was performed on 20 mumps virus isolates: all were genotype J. A prolonged outbreak of mumps occurred in a well defined, highly vaccinated, predominantly young Aboriginal population in the remote Kimberley region of WA. This outbreak raises questions about the effectiveness and scheduling of the current vaccine (which is genotype A-derived), especially for Aboriginal people. Surveillance of circulating mumps virus genotypes and neutralisation studies will help in evaluating the protection provided by the current vaccine against genotypically different strains.

    The province of Ontario continues to experience measles virus transmissions despite the elimination of measles in Canada. We describe an unusual outbreak of measles in Ontario, Canada, in early 2015 that involved cases with a unique strain of virus and no known association among primary case-patients. A total of 18 cases of measles were reported from 4 public health units during the outbreak period (January 25-March 23, 2015); none of these cases occurred in persons who had recently traveled. Despite enhancements to case-patient interview methods and epidemiologic analyses, a source patient was not identified. However, the molecular epidemiologic analysis, which included extended sequencing, strongly suggested that all cases derived from a single importation of measles virus genotype D4. The use of timely genotype sequencing, rigorous epidemiologic investigation, and a better understanding of the gaps in surveillance are needed to maintain Ontario's measles elimination status.

    Full Text Available INTRODUCTION. In view of the goal of measles elimination, it is of great importance to assess the circulation of wild-type measles virus (MV. Genetic analysis is indispensable to understand the epidemiology of measles. A large measles outbreak occurred in Italy in 2008, with over 4000 cases reported to the enhanced measles surveillance system introduced in 2007, 37% of which were laboratory confirmed. METHODS. Urine and saliva samples were collected during 2008. A phylogenetic analysis of measles sequences was performed in order to understand the epidemiological situation of wild-type (MV circulation in that period. RESULT AND DISCUSSION. Data showed predominant circulation of the genotype D4. Genotypes A, D8, D9 and H1 were also detected in a small number of samples, probably representing imported cases.

    2017-05-01

    The Government of India is accepted to participate in the measles elimination and rubella control goal 2020, hence genetic characterization of measles viruses (MeV) becomes essential. At National Reference Laboratory (National Institute of Virology, Pune), the throat swabs/urine specimens (n = 380) or PCR products (n = 219) obtained from the suspected measles cases were referred for the molecular testing and subsequently, MeV nucleoprotein (N) gene sequencing/genotyping. In addition, 2,449 suspected measles cases, mainly from the Maharashtra state were referred for the laboratory diagnosis. A detailed study was performed on N gene sequences obtained during last two decades. Indian MeV sequences obtained during 2011-2015 were compared with 1996-2010 sequences and genetic divergence was studied. Circulation of measles genotypes B3 (n = 3), D4 (n = 49), and D8 (n = 351) strains were observed in 19 States and three Union Territories of India. In addition, 64 measles viruses were isolated from 253 throat swab or urine specimens obtained from the suspected measles cases. During 2011-2015, 67.9% (1,663/2,449) suspected measles cases were laboratory confirmed. Molecular studies showed circulation of measles genotype B3 in India along with prominently circulating genotypes D4 and D8 except D7 strains. The genetic diversion within Indian B3, D4, and D8 genotypes was 0.3%, 1.1%, and 2.1%, respectively. The genetic divergence of Indian B3, D4, and D8 measles strains with the WHO reference sequences was 2.5%, 2.6%, and 1.8%, respectively. It is crucial data for national immunization program. More measles/rubella genotyping studies are necessary to track transmission and to support measles elimination and rubella control. J. Med.

    Full Text Available Introduction: Measles is a highly infectious viral illness that remains one of the leading causes of death among children worldwide. In the Philippines, decreasing routine vaccination coverage from 2007 to 2011 led to local measles outbreaks. A team investigated a measles outbreak reported in Cordillera of the Philippines in May 2013. Methods: Measles case data with symptom onset from 2 February to 27 May 2013 were obtained from official sources and verified on site. Data included age, sex, residential address, signs and symptoms and vaccination status. Active case-findings were also conducted for contacts of these cases. The living environments of the cases were investigated. A survey was conducted with the cases and caregivers to understand their knowledge and attitudes about measles. Results: There were 50 measles cases identified with an age range from six months to 32 years (median: 16 years. Thirty-two were male (64%. Twenty (40% were hospitalized with one death. Thirty-two (64% cases were laboratory confirmed, and 36 (72% received a single dose of measles vaccine. Overcrowded living environments were observed among many cases. The majority of respondents (46/48, 96% knew about measles, but there were misconceptions about the cause of measles and how it can be prevented and managed. Conclusion: This measles outbreak occurred in an area with low immunization coverage. Achieving 95% measles immunization coverage and strengthening routine immunization strategies to address high-risk populations are recommended. Also, we recommend health education campaigns to include components that address misconceptions about measles.

    In line with the worldwide strive to combat measles, the Swiss Federal Office of Public Heath (FOPH) launched a National Strategy for measles elimination 2011-2015. In this study, we highlight the importance of travel medicine consultations to complement measles vaccination programmes based on data from the Travel Clinic of the University of Zurich. We analysed measles vaccination data from the Zurich Travel Clinic between July 2010 and February 2016 and focused on three groups: (i) all clients who received the measles vaccination, (ii) all clients aged>two years who received the measles vaccination ("catch-up vaccination"), and (iii) all clients aged>two years and born after 1963 ("FOPH recommended catch-up vaccination"). 107,669 consultations were performed from 2010 to 2016. In 12,470 (11.6%) of these, a measles vaccination was administered; 90.9% measles vaccinations were given during a pre-travel consultation, and 99.4% were administered to individuals aged>two years ("catch-up vaccinations"). An "FOPH recommended catch-up vaccination" was received by 13.6% of all Zurich Travel Clinic clients aged >2years and born after 1963. In this study, we highlight the importance of travel medicine consultations to enhance the measles vaccination coverage in the adult Swiss population. Copyright © 2017 Elsevier Ltd.

    2008-05-01

    Mumps outbreaks continue to occur throughout the world, including in highly vaccinated populations. Vaccination against mumps has been successful; however, humoral and cellular immune responses to mumps vaccines vary significantly from person to person. We set out to assess whether HLA and cytokine gene polymorphisms are associated with variations in the immune response to mumps viral vaccine. To identify genetic factors that might contribute to variations in mumps vaccine-induced immune responses, we performed HLA genotyping in a group of 346 healthy schoolchildren (12-18 years of age) who previously received 2 doses of live mumps vaccine. Single-nucleotide polymorphisms (minor allele frequency of >5%) in cytokine and cytokine receptor genes were genotyped for a subset of 118 children. Median values for mumps-specific antibody titers and lymphoproliferative stimulation indices were 729 IU/mL and 4.8, respectively. Girls demonstrated significantly higher mumps antibody titers than boys, indicating gender-linked genetic differences in humoral immune response. Significant associations were found between the HLA-DQB1*0303 alleles and lower mumps-specific antibody titers. An interesting finding was the association of several HLA class II alleles with mumps-specific lymphoproliferation. Alleles of the DRB1 (*0101, *0301, *0801, *1001, *1201, and *1302), DQA1 (*0101, *0105, *0401, and *0501), and DQB1 (*0201, *0402, and *0501) loci were associated with significant variations in lymphoproliferative immune responses to mumps vaccine. Additional associations were observed with single-nucleotide polymorphisms in the interleukin-10RA, interleukin-12RB1, and interleukin-12RB2 cytokine receptor genes. Minor alleles for 4 single-nucleotide polymorphisms within interleukin-10RA and interleukin-12RB genes were associated with variations in humoral and cellular immune responses to mumps vaccination. These data suggest the important role of HLA and immunoregulatory cytokine receptor

  20. Immunogenicity of UV-inactivated measles virus

    Zahorska, R.; Mazur, N.; Korbecki, M.

    1978-01-01

    By means of the antigen extinction limit test it was shown that a triple dose vaccination of guinea pigs with UV-inactivated measles virus gave better results, than a single dose vaccination which was proved by the very low immunogenicity index. For both vaccination schemes (single and triple) the immune response was only sligthly influenced by a change of dose from 10 5 to 10 6 HadU 50 /ml or by the addition of aluminum adjuvant. In the antigen extinction limit test the antibody levels were determined by two methods (HIT and NT) the results of which were statistically equivalent. The UV-inactivated measles virus was also found to induce hemolysis-inhibiting antibodies. (orig.) [de

    Recent mumps outbreaks in older vaccinated populations were caused primarily by genotype G viruses, which are phylogenetically distinct from the genotype A vaccine strains used in the countries affected by the outbreaks. This finding suggests that genotype A vaccine strains could have reduced efficacy against heterologous mumps viruses. The remote history of vaccination also suggests that waning immunity could have contributed to susceptibility. To examine these issues, we obtained consecutive serum samples from children at different intervals after vaccination and assayed the ability of these samples to neutralize the genotype A Jeryl Lynn mumps virus vaccine strain and a genotype G wild-type virus obtained during the mumps outbreak that occurred in the United States in 2006. Although the geometric mean neutralizing antibody titers against the genotype G virus were approximately one-half the titers measured against the vaccine strain, and although titers to both viruses decreased with time after vaccination, antibody induced by immunization with the Jeryl Lynn mumps vaccine strain effectively neutralized the outbreak-associated virus at all time points tested.

    This report describes the immunogenicity and efficacy and long term immunity of Hoshino strain of Mumps (included in MMR Vaccine) in shahr-e-kord, Islamic Republic of Iran (I.R.Iran). A total of 338 Children aged 3-18 years were tested for Mumps IgG using enzyme-linked immunosorbent assay (ELISA). The proportion of susceptible, mumps IgG negative, children was 19.8% (67 subjects). Of the 67 susceptible children, 36 received the MMR vaccination and successfully completed the study. Blood was collected by venipuncture 3, 12, and 24 months after vaccination and serum samples were tested by ELISA for detection of Mumps IgM and IgG. The overall seroconversion rate was 86.1%, 77.7% and 75% at 3, 12, and 24 months after vaccination respectively.

    To characterize the association between county-level risk factors and the incidence of mumps in the 2006 Iowa outbreak, we used generalized linear mixed models with the number of mumps cases per county as the dependent variable. To assess the impact of spring-break travel, we tested for differences in the proportions of mumps cases in three different age groups. In the final multivariable model, the proportion of Iowa's college students per county was positively associated (Pstudents in a county were spread among more campuses, this was associated with fewer mumps cases. Finally, we found the proportion of mumps cases in both older and younger persons increased after 1 April (P=0.0029), suggesting that spring-break college travel was associated with the spread of mumps to other age groups.

    2017-12-01

    A cluster of parotitis cases (n = 13) were observed in a tribal population of Vansda village from the Union Territory of Dadra and Nagar Haveli, India between 20th and 22nd week of 2016. Primary information was received by the local Infectious Disease Surveillance Program team, and subsequently field investigations were carried out in the affected area. Active surveillance was conducted till twice the incubation period from onset of the last surveyed case. For the laboratory investigations, 19 serum samples were collected from 11-suspected cases and their close contacts (n = 8). All samples were transported within 12 h on icepacks to the main laboratory at Pune. Majority of the suspected mumps cases were children except four adults. Mumps infection was confirmed in 8 of 11 suspected cases with post-onset ranging from 28 to 43 days and none from the close contacts. Both mumps specific IgM and IgG antibodies were detected in nine cases (including one equivocal) and single contact (equivocal result). Overall, ten cases and eight contacts (including one equivocal) showed mumps specific IgG antibodies. Present investigation provides information about the characteristics of mumps outbreak in a tribal community that resides in the remote areas. In addition, introduction of mumps containing vaccine in the tribal population may have added advantages in the tribal health program. © 2017 Wiley Periodicals, Inc.

    Full Text Available Objective: The objective of this study was to determine the prevalence of IgG antibodies against mumps in a representative stratified sample of children under 18 years of age in Pleven district, Bulgaria. Study Design: Cross sectional study. Materials and Methods: A cross-sectional, sero-epidemiologic survey of 132 children aged under 18 years was conducted in Pleven district. They were distributed into two age groups: from 0 to 11 years old (n=80 and from 12 to 18 years old (n=52. An enzyme immunoassay (EIA was performed for indirect evidence of specific IgG antibodies in the serum. Results: The results showed that 41% of the investigated children were negative in terms of mumps IgG antibodies, 11% had borderline values and the remaining, approximately 48%, were positive. In the group of children aged 0 to 11 years who had received one dose of the mumps vaccine, 50% were negative for mumps IgG antibodies. In the second group of children aged 12 to 18 years who had received two vaccine doses, the percentage of participants negative for mumps IgG antibodies decreased significantly. Conclusion: Our observations emphasise the need to conduct expanded sero-epidemiological investigations of the populations most affected by mumps and to immunise susceptible individuals.

    2008-07-01

    Full Text Available Abstract Background The most often used mumps vaccine strains Jeryl Lynn (JL, RIT4385, Urabe-AM9, L-Zagreb and L-3 differ in immunogenicity and reactogenicity. Previous analyses showed that JL, Urabe-AM9 and L-3 are genetically heterogeneous. Results We identified the heterogeneity of L-Zagreb throughout the entire genome. Two major variants were defined: variant A being identical to the consensus sequence of viral seeds and vaccine(s and variant B which differs from variant A in three nucleotide positions. The difference between viral variants in L-Zagreb strain is insufficient for distinct viral strains to be defined. We demonstrated that proportion of variants in L-Zagreb viral population depends on cell substrate used for viral replication in vitro and in vivo. Conclusion L-Zagreb strain should be considered as a single strain composed of at least two variant viral genomes.

    2006-01-01

    The fusion proteins of enveloped viruses mediating the fusion between the viral and cellular membranes comprise two discontinuous heptad repeat (HR) domains located at the ectodomain of the enveloped glycoproteins. The crystal structure of the fusion protein core of Mumps virus (MuV) was determined at 2.2 A resolution. The complex is a six-helix bundle in which three HR1 peptides form a central highly hydrophobic coiled-coil and three HR2 peptides pack against the hydrophobic grooves on the surface of central coiled-coil in an oblique antiparallel manner. Fusion core of MuV, like those of simian virus 5 and human respiratory syncytium virus, forms typical 3-4-4-4-3 spacing. The similar charecterization in HR1 regions, as well as the existence of O-X-O motif in extended regions of HR2 helix, suggests a basic rule for the formation of the fusion core of viral fusion proteins

    Measles is a highly communicable viral illness and is common cause of childhood mortality and morbidity. Keeping in view the high prevalence of measles in the developing world, we carried out this study to look into the complicated measles cases and clinical outcome in patients admitted in children ward of Ayub Teaching Hospital. Detailed history and physical examination of all the hospitalized patients with complication of measles were recorded in a proforma. Immunization and nutritional status of each admitted patient was assessed and the clinical outcome of measles was compared with demographic profile. one hundred thirty six hospitalized patients with complications of measles were studied. There was 60.3% male and 57.3% of patients were vaccinated against measles. Malnourished patients were 71.35% and had longer hospital stay (>5 days). Pneumonia (39.7%) and diarrhoea (38.2%) were the commonest complications. Seven children died and encephalitis (57.1%) was the commonest cause of death. The most common complications of measles are pneumonia and diarrhoea with dehydration requiring admission. Malnutrition results in more complications and longer hospital stay. Mortality is significantly associated with encephalitis. (author)

    World Health Organization (WHO) measles surveillance data report a reduction in cases of measles globally from 67,524 cases in 2015 to 16,846 in 2016, and a reduction in deaths from 546,800 to 114,900 during period of 2000-14. Pakistan is among the five nations where almost a million children did not receive their first dose of measles vaccination, and outbreaks of the disease resulted in 4386 cases in 2011, 14,687 cases in 2012 with 310 deaths. In 2013, about 25,401 cases of measles were reported and 321 affected children died. The measles vaccination coverage is very low in Pakistan for both 1st dose and booster dose. To prevent outbreaks of measles in Pakistan a national vaccination program should be launched side by side with a polio eradication program in each district and township and a campaign should be launched to educate parents on measles vaccination for childrens to reduce the measles case fatality rate.

  6. Modelling the effects of treatment and quarantine on measles

    Beay, Lazarus Kalvein

    2018-03-01

    Treatment and quarantine are efforts to cure as well as to overcome the spread of diseases including measles. The spread of measles can be expressed by mathematical modelling in the form of nonlinear dynamical systems. In this study was conducted on the spread of measles by considering the effect of treatment and quarantine on the infected individuals. By using the basic reproduction number of the model, can be analyzed the effects of treatment and quarantine to reduce the spread of measles. Basic reproduction number of models is monotonically descreasing as treatment and quarantine increasing. Numerical simulations conducted on the analysis of the results. The results showed that treatment and quarantine was given to infected individuals who were infectious has a major influence to eliminate measles from the system.

    Measles has been declared eliminated from the Korea since 2006. In April 2014, a measles outbreak occurred at a University in Seoul. A total of 85 measles cases were identified. In order to estimate vaccine effectiveness of measles vaccine, we reviewed the vaccination records of the university students. The vaccine effectiveness of two doses of measles containing vaccine was 60.0% (95% CI, 38.2-74.1; P < 0.05). Transmission was interrupted after the introduction of outbreak-response immunization. The outbreak shows that pockets of under-immunity among college students may have facilitated the disease transmission despite the high 2-dose vaccination coverage in the community. © 2017 The Korean Academy of Medical Sciences.

    The currently used live-attenuated measles vaccine is very effective although maternal antibody prevents its administration prior to 6 months of age. We are investigating the ability of a DNA vaccine encoding the measles viral hemagglutinin, fusion and nucleoprotein to protect newborn infants from measles. Here, we show that a measles DNA vaccine protects juvenile macaques from pathogenic measles virus challenge and that macaques primed and boosted with this DNA vaccine have anemnestic antibody and cell-mediated responses after vaccination with a live-attenuated canine distemper-measles vaccine. Therefore, this DNA vaccine administered to newborn infants may not hinder the subsequent use of live-attenuated measles vaccine.

    The Republic of Korea declared measles elimination in 2006. However, a measles outbreak occurred in 2013. This study aimed to identify the epidemiological characteristics of the sources of infection and the pattern of measles transmission in 2013 in South Korea. We utilized surveillance data, epidemiological data, immunization registry data, and genetic information. We describe the epidemiological characteristics of all measles case patients (sex, age distribution, vaccination status, sources of infection) as well as details of the outbreak (the pattern of transmission, duration, mean age of patients, and generation time). In 2013, a total of 107 measles cases were notified. Most patients were infants (43.0%) and unvaccinated individuals (60.7%). We identified 4 imported and 103 import-related cases. A total of 105 cases were related to four outbreaks that occurred in Gyeongnam, northern Gyeonggi, southern Gyeonggi, and Seoul. The predominant circulating genotype was B3 type, which was identified in the Gyeongnam, northern Gyeonggi, and southern Gyeonggi outbreaks. The B3 type had not been in circulation in South Korea in the previous 3 years; virologic evidence suggests that these outbreaks were import-related. Most measles cases in South Korea have been associated with imported measles virus. Although Korea has maintained a high level of herd immunity, clustering of susceptible people can cause such measles outbreaks.

    In this study, we have described the clinical characteristics of vaccine-modified measles to assess the performance of an expanded case definition in a school outbreak that occurred in 2010. The sensitivity, specificity, and the positive and negative predictive values were evaluated. Among 74 cases of vaccine-modified measles, 47 (64%) met the original case definition. Fever and rash were observed in 73% (54/74); fever was the most common (96%, 71/74) presenting symptom, and rash was noted in 77% (57/74) of the cases. The original case definition showed an overall sensitivity of 63.5% and a specificity of 100.0%. The expanded case definition combining fever and rash showed a higher sensitivity (72.9%) but a lower specificity (88.2%) than the original. The presence of fever and one or more of cough, coryza, or conjunctivitis scored the highest sensitivity among the combinations of signs and symptoms (77.0%), but scored the lowest specificity (52.9%). The expanded case definition was sensitive in identifying suspected cases of vaccine-modified measles. We suggest using this expanded definition for outbreak investigation in a closed community, and consider further discussions on expanding the case definition of measles for routine surveillance in South Korea.

  15. Seroprevalence of transplacentally acquired measles antibodies in HIV-exposed versus HIV-unexposed infants at six months of age

    Sneha Jain

    2017-01-01

    Interpretation & conclusions: Most HEI lacked measles antibodies at six months age and were, therefore, more vulnerable to measles than HUnI. Seroconversion in response to a single dose of measles vaccine administered at six months age was low in these infants, signifying the need of additional dose(s of measles/measles-containing vaccine.

  16. Emergency measles control activities--Darfur, Sudan, 2004.

    2004-10-01

    The Darfur region of Sudan, composed of three states with a population of approximately six million, has experienced civil conflict during the previous year, resulting in the internal displacement of approximately one million residents and an exodus of an estimated 170,000 persons to neighboring Chad. The conflict has left a vulnerable population with limited access to food, health care, and other basic necessities. In addition, measles vaccination coverage has been adversely affected; in 2003, coverage was reported to be 46%, 57%, and 77% in North, West, and South Darfur, respectively. This report describes measles-control activities in Darfur region conducted by the Federal Ministry of Health (FMOH) in Sudan in collaboration with the United Nations and nongovernmental organizations (NGOs) during March-August 2004. Ongoing measles transmission in camps for internally displaced persons (IDPs) and neighboring communities in Darfur led to a regionwide measles vaccination campaign targeting all children aged 9 months-15 years, resulting in a reduction in reported measles cases. Once security is improved, ongoing efforts to increase measles vaccine coverage will be required to eliminate persistent susceptibility to measles in the Darfur population.

  17. A Recombinant Measles Vaccine with Enhanced Resistance to Passive Immunity.

    Julik, Emily; Reyes-Del Valle, Jorge

    2017-09-21

    Current measles vaccines suffer from poor effectiveness in young infants due primarily to the inhibitory effect of residual maternal immunity on vaccine responses. The development of a measles vaccine that resists such passive immunity would strongly contribute to the stalled effort toward measles eradication. In this concise communication, we show that a measles virus (MV) with enhanced hemagglutinin (H) expression and incorporation, termed MVvac2-H2, retained its enhanced immunogenicity, previously established in older mice, when administered to very young, genetically modified, MV-susceptible mice in the presence of passive anti-measles immunity. This immunity level mimics the sub-neutralizing immunity prevalent in infants too young to be vaccinated. Additionally, toward a more physiological small animal model of maternal anti-measles immunity interference, we document vertical transfer of passive anti-MV immunity in genetically-modified, MV susceptible mice and show in this physiological model a better MVvac2-H2 immunogenic profile than that of the parental vaccine strain. In sum, these data support the notion that enhancing MV hemagglutinin incorporation can circumvent in vivo neutralization. This strategy merits additional exploration as an alternative pediatric measles vaccine.

    2017-01-01

    Full Text Available Background: Thirty-one cases of fever with rash were reported among students of a college in Pune, India, from March to May 2014. The clinical profile was similar to that of measles and 7 of them tested positive for measles-specific immunoglobulin M (IgM. An outbreak of measles was declared, and epidemiological investigation was carried out to assess the situation and suggest preventive measures. Methods: An epidemiological case sheet filled for each case to identify the source and likely contacts. Medical and administrative authorities were sensitized about the increase in incidence and clustering of cases. A surveillance system was set up for detection of new cases and follow-up of contacts. Throat swabs and blood samples from 12 cases were tested by ELISA method for commonly occurring viral exanthematous fevers to confirm the diagnosis and 7 were positive for measles-specific IgM antibody. Preventive measures were advised to control the outbreak. Results: A total of 31 cases of fever with rashes were reported among students of a college in Pune, India, during the months of March–May 2014. Most of the students were in the age group of 18–24 years. Samples from 12 cases were sent for testing and 7 tested positive for measles-specific IgM antibodies. Seven cases were epidemiologically linked to a lab-confirmed case. All cases had fever, maculopapular rash, and sore throat and gave a history of vaccination for measles in childhood. Conclusion: An epidemiological investigation was carried out for outbreak of measles in a young adult population of college students from Pune. It is reported that, with increase in overall coverage of vaccination, there is a rise in incidence of measles in vaccinated individuals. The age profile also shifts to higher age groups. Investigation of such outbreaks provides an opportunity to identify high-risk groups, changes in measles epidemiology and weaknesses in the routine immunization programs.

    2017-01-01

    Background Measles vaccination over the past 50 years has greatly reduced the incidence of measles. However, measles among migrants and the resulting changes in epidemiological characteristics have brought new challenges to the elimination of measles. We aim to describe the measles epidemic trend over the past 30 years in a central district in Shanghai, China. Methods The present study was conducted in the Jing’an District, which is located in the center of Shanghai. Based on historical surveillance data of measles, we calculated the incidence of measles among local residents and migrants separately. Next, we classified all of the cases of the measles among local residents between 1984 and 2015 into 8 age groups and 5 birth cohorts. Finally, we calculated the measles incidence in each time period by the different age groups and birth cohorts, to understand the measles epidemic trend over past 30 years in the Jing'an District. Results A total of 103 cases of measles were reported from the Jing’an District, Shanghai, from 1984 to 2015. For infants less than 1 year of age and adults over 30 years of age, the incidence of measles continued to rise over the past 30 years. For a specific birth cohort, the incidence of measles after measles vaccination declined initially, and was then followed by a rebound. Conclusions The incidence of measles in older adults and infants increased in some developed regions, which slows the process of measles elimination. This suggested that the population immunity against measles after measles vaccination would gradually reduce with time. We recommend supplemental immunization against measles in adults in order to reduce the immunity decline, especially for migrants. PMID:28640919

  2. A comparative analysis of measles virus RNA by oligonucleotide fingerprinting

    Stephenson, J.R.; Meulen, V. ter

    1982-01-01

    Isolates from two cases of acute measles, one case of acute measles encephalitis and three patients with subacute sclerosing panencephalitis were compared. This comparison was based upon the electrophoretic analysis of T 1 oligonucleotides from single-stranded, full-length RNA isolated from cytoplasmic nucleocapsids. Although all viruses have oligonucleotides in common, each isolate generated a unique pattern of oligonucleotides. However, no group of oligonucleotides was observed which would allow differentiation between viruses isolated from acute infections and those isolated from CNS diseases; indicating that probably all measles viruses differ in their nucleotide sequence, regardless of origin.

  3. Easy and Rapid Detection of Mumps Virus by Live Fluorescent Visualization of Virus-Infected Cells.

    Tadanobu Takahashi

    Full Text Available Mumps viruses show diverse cytopathic effects (CPEs of infected cells and viral plaque formation (no CPE or no plaque formation in some cases depending on the viral strain, highlighting the difficulty in mumps laboratory studies. In our previous study, a new sialidase substrate, 2-(benzothiazol-2-yl-4-bromophenyl 5-acetamido-3,5-dideoxy-α-D-glycero-D-galacto-2-nonulopyranosidonic acid (BTP3-Neu5Ac, was developed for visualization of sialidase activity. BTP3-Neu5Ac can easily and rapidly perform histochemical fluorescent visualization of influenza viruses and virus-infected cells without an antiviral antibody and cell fixation. In the present study, the potential utility of BTP3-Neu5Ac for rapid detection of mumps virus was demonstrated. BTP3-Neu5Ac could visualize dot-blotted mumps virus, virus-infected cells, and plaques (plaques should be called focuses due to staining of infected cells in this study, even if a CPE was not observed. Furthermore, virus cultivation was possible by direct pick-up from a fluorescent focus. In conventional methods, visible appearance of the CPE and focuses often requires more than 6 days after infection, but the new method with BTP3-Neu5Ac clearly visualized infected cells after 2 days and focuses after 4 days. The BTP3-Neu5Ac assay is a precise, easy, and rapid assay for confirmation and titration of mumps virus.

  4. Emergent lineages of mumps virus suggest the need for a polyvalent vaccine.

    May, Meghan; Rieder, Courtney A; Rowe, Rebecca J

    2018-01-01

    Mumps outbreaks among vaccinated patients have become increasingly common in recent years. While there are multiple conditions driving this re-emergence, convention has suggested that these outbreaks are associated with waning immunity rather than vaccine escape. Molecular evidence from both the ongoing American and Dutch outbreaks in conjunction with recent structural biology studies challenge this convention, and suggest that emergent lineages of mumps virus exhibit key differences in antigenic epitopes from the vaccine strain employed: Jeryl-Lynn 5. The American and Dutch 2016-2017 outbreak lineages were examined using computational biology through the lens of diversity in immunogenic epitopes. Findings are discussed and the laboratory evidence indicating neutralization of heterologous mumps strains by serum from vaccinated individuals is reviewed. Taken together, it is concluded that the number of heterologous epitopes occurring in mumps virus in conjunction with waning immunity is facilitating small outbreaks in vaccinated patients, and that consideration of a polyvalent mumps vaccine is warranted.

    Although major mumps epidemics occurred every 4-5 years in Okinawa Prefecture in Japan, no laboratory diagnoses were conducted. A mumps epidemic started in Okinawa in October 2014, and we collected clinical samples from 31 patients in 4 areas (Hokubu, Nanbu, Miyako, and Yaeyama) from July to December 2015, for virus isolation and RT-PCR, whose positive ratios were 52% and 87%, respectively. Phylogenetic analyses showed that all isolates were classified into genotype G, and with one exception, consisted of 2 subgenotypes, Ge (55.6%) and Gw (40.7%), which have been prominent in Japan recently. One isolate was classified in another lineage, which was detected in Japan for the first time, and was similar to a Hong Kong isolate from 2014. Remarkably, the geographic distributions of the 2 major lineages were separated. The Ge viruses were isolated from the main island of Okinawa and the Yaeyama Islands, whereas the Gw isolates were mainly detected from the Miyako Islands. These results suggest that the Ge and Gw mumps viruses mainly caused the mumps epidemics of 2015 in Okinawa, and that they spread independently in separate regions. This is the first report describing the molecular epidemiology of mumps epidemics in Okinawa Prefecture.

  6. [EIA-IgG antibody measles prevention level estimated from measles neutralizing, particle agglutination and hemagglutination-inhibition antibody titer].

    Takayama, Naohide; Saika, Shizuko; Ichinohe, Sadato

    2009-09-01

    Measles hemagglutination inhibition (HI) antibody titer, widely used in clinical practice to simply and easily determine the measles immunity level has, in recent years, been increasingly replaced by measles IgG-antibody titer determined by enzyme-immunoassay (EIA). HI antibody titer appears to reflect this protective level, because HI measures the antibody against H protein required for the measles virus to adhere to host cells. EIA-IgG antibody titer does not correlate with the protective level, similar to particle agglutination (PA) titer, because EIA measures different antibodies, including those unrelated to measles protection. After determining HI, PA, neutralizing test (NT) results, and EIA-IgG antibody titer for individual specimens, we compared EIA-IgG antibody titer obtained using an EIA-Kit (Denka Seiken) to HI, PA, and NT titer with the following results: (1) Subjects with EIA-IgG titer of > or = 12.0 may be protected against measles: (2) Subjects with EIA-IgG titer of 4.0 to 8.0 appear to be protected insufficiently requiring a booster dose against measles: (3) Subjects with EIA-IgG titer of 8.0 to 12.0 may benefit from booster vaccination.

    Despite an ongoing measles elimination programme, a measles outbreak occurred in 2013 in Turkey. Population-based seroprevalence studies are needed to determine seronegativity and explore the reasons for this outbreak. This study aimed to explore the seroprevalence of measles and its association with various social determinants in a provincial population in Turkey in the year following a measles outbreak. Cross-sectional study. This study was conducted in Manisa Province in 2014 in a sample of 1740 people aged >2 years. The dependent variable was the seroprevalence of measles. Independent variables were sex, age, migration, household size, household density, income, education level, existence of chronic disease and occupational class. Blood samples were collected from participants at family health centres. The presence of specific measles antibodies in serum samples was determined using an anti-measles virus IgG enzyme-linked immunosorbent assay test. Chi-squared test and logistic regression analysis were performed. Overall, data from 1250 people were analysed. The seroprevalence of measles in the whole study population was 82.2% (95% confidence interval 80.0-84.2). Seroprevalence was 55.4% among subjects aged 2-9 years, 48.7% among subjects aged 10-19 years, 74.1% among subjects aged 20-29 years and 93.6% among subjects aged 30-39 years (P 40 years was >95%. The lowest seroprevalence was found in primary school children (40.2%), followed by those below the age for primary education (69.8%) and secondary school graduates (75.1%). The prevalence of measles seronegativity was not associated with any of the social determinants when adjusted for age. The seroprevalence of measles was lower than expected in the study population and was particularly low in subjects aged measles elimination targets, suggesting that it may be necessary to re-evaluate the need for an extra dose of measles vaccine.

    Measles cases are increasing in Ireland, with 320 cases notified since August 2009. Nearly two-thirds of these cases (n=206) were unvaccinated. In the early stages of the outbreak a substantial number of cases were linked to the Traveller community with some cases also reported among the Roma community, other citizens from eastern Europe and children whose parents objected to vaccination. By February 2010, there had been considerable spread to the general population.

  11. Mumps vaccine virus genome is present in throat swabs obtained from uncomplicated healthy recipients.

    Nagai, T; Nakayama, T

    2001-01-08

    Seven children were followed for up to 42 days post-vaccination with live mumps vaccine and 37 throat swabs were obtained serially. Viral genomic RNA was detected by reverse transcription-polymerase chain reaction (RT-PCR) in the phosphoprotein (P) and hemagglutinin-neuraminidase (HN) regions. Virus isolation was also attempted. Genomic differentiation of detected mumps virus genome was performed by sequence analysis and/or restriction fragment length polymorphism (RFLP). No adverse reaction was observed in these children. Although mumps virus was not isolated from any of the samples, viral RNA was detected in four samples from three vaccine recipients, 18, 18 and 26, and 7 days after vaccination, respectively. Detected viral RNA was identified as the vaccine strain. Our data suggests that vaccine virus inoculated replicates in the parotid glands but the incidence of virus transmission from recipients to other susceptible subjects should be low.

    On January 5, 2015, the California Department of Public Health (CDPH) was notified about a suspected measles case. The patient was a hospitalized, unvaccinated child, aged 11 years with rash onset on December 28. The only notable travel history during the exposure period was a visit to one of two adjacent Disney theme parks located in Orange County, California. On the same day, CDPH received reports of four additional suspected measles cases in California residents and two in Utah residents, all of whom reported visiting one or both Disney theme parks during December 17-20. By January 7,seven California measles cases had been confirmed, and CDPH issued a press release and an Epidemic Information Exchange (Epi-X) notification to other states regarding this outbreak. Measles transmission is ongoing.

    2016-10-01

    To quantify the impact on mortality of offering a hypothetical set of technically feasible, high-impact interventions for maternal and child survival during India's 2010-2013 measles supplementary immunization activity. We developed Lives Saved Tool models for 12 Indian states participating in the supplementary immunization, based on state- and sex-specific data on mortality from India's Million Deaths Study and on health services coverage from Indian household surveys. Potential add-on interventions were identified through a literature review and expert consultations. We quantified the number of lives saved for a campaign offering measles vaccine alone versus a campaign offering measles vaccine with six add-on interventions (nutritional screening and complementary feeding for children, vitamin A and zinc supplementation for children, multiple micronutrient and calcium supplementation in pregnancy, and free distribution of insecticide-treated bednets). The measles vaccination campaign saved an estimated 19 016 lives of children younger than 5 years. A hypothetical campaign including measles vaccine with add-on interventions was projected to save around 73 900 lives (range: 70 200-79 300), preventing 73 700 child deaths (range: 70 000-79 000) and 300 maternal deaths (range: 200-400). The most effective interventions in the whole package were insecticide-treated bednets, measles vaccine and preventive zinc supplementation. Girls accounted for 66% of expected lives saved (12 712/19 346) for the measles vaccine campaign, and 62% of lives saved (45 721/74 367) for the hypothetical campaign including add-on interventions. In India, a measles vaccination campaign including feasible, high-impact interventions could substantially increase the number of lives saved and mitigate gender-related inequities in child mortality.

    Measles, a virus borne droplet infection, is one of the leading causes of death among young children worldwide despite presence of a safe and cost-effective vaccine. Objective of our study was to identify the characteristics of measles patients admitted to Allied Hospitals, Rawalpindi. Methods: This cross-sectional study was conducted amongst patients admitted with measles in paediatric units of Rawalpindi Medical College Allied Hospitals, Rawalpindi. A standard proforma was used to collect data from the respondents. Results: A total of 55 patients (mean age-29.36 months) with measles were included in the study. 65.5% children were vaccinated while 34.5% were not vaccinated. Among those vaccinated 14 were male. Out of the vaccinated children 52.6% were residents of middle class areas, 31.6% lower middle class area, 10.5% upper middle class areas and 5.3% rural areas. In 55.0% of patients who were vaccinated with at least one dose of measles at nine month of age the estimated calendar months of vaccination was March to April while in 30% the overall climatic period of vaccination was of summer (May to September). Twenty one study subjects were exposed to a case of measles in the family and thirty five out of all developed at least one known complication of the disease. Pneumonia was the most common complication reported in patients (63.6%) followed by diarrhoea (27.3%). Conclusion: Majority of the patients suffering from measles were not vaccinated and the most common reason for failure to immunize children was lack of awareness. Educated and well off fathers were more likely to get their children immunized. The vaccinated children who developed measles majority were vaccinated during months of March, April and May. (author)

  20. STUDY ON SEROPREVALENCE OF MUMPS - SPECIFIC IgG ANTIBODIES IN A HEALTHY POPULATION

    2010-09-01

    Full Text Available Mumps is a vaccine preventable viral infection. Its typical clinical manifestations are characterized by pain and swelling of the salivary glands, fever, and fatigue. Often other organs are affected - testes in males after puberty (orchitis, ovaries in women (ooforitis, pancreas (pancreatitis, central nervous system (meningities. The use of specific immune prophylaxis led to a significant success in the fight against mumps, but there are still unresolved issues related to the immunological and epidemiological effectiveness of the vaccines. The disease continues to interest researchers today. The main issues being tackled are related to the conduct of virological, clinical and sero-epidemiological studies in different countries. Objectives of the study is to determine the frequency distribution of mumps-specific IgG antibodies in healthy populations in the region of Pleven, Bulgaria. Methods: a cross-sectional sero - epidemiological representative population - based survey in the area was made. Enzyme immunoassay method was used for an indirect proof of mumps - specific IgG serum antibodies. 410 people were examined at an average age of 25 (1 to 84. Of these, 250 (61 % were women and 160 (39 % - men. Results: Of all test results, the negative were 72 (19 %, the borderline were 12 (3 %, the positive were 182 (44 %, and highly positive were 144 (35 %. The vaccination status showed that 242 (69 % of all surveyed were immunized with a vaccine against mumps. According to the immunization schedule in Bulgaria, 132 (33 % people were immunized with monovaccine during the years - 1 intake, 80 (20 % with trivaccine - 1 intake, and 64 (16 % - 2 doses. Conclusion: We believe that despite the specific immunprophylaxis carried out against mumps decades on end, the necessary level of protection leading to its elimination has not yet been reached.

    Many measles cases in Tianjin, China, occur in infants whose mothers were born after widespread vaccination programs. We assessed age-specific decreases in maternal measles antibodies in infants and examined maternal and infant characteristics in relation to infant antibody titers. Infant and mother dyads were enrolled from a sample of immunization clinics in all Tianjin districts. Participants' antibody titers were measured from dried blood spots. A multivariable log-linear model regressed infant antibody titers onto infant and mother characteristics. Among 551 infants aged ≤8 months, protective levels of measles antibodies were observed in infants whose mothers had measles titers ≥800 IU/mL (mean antibody titer, 542.5 IU/mL) or 400 to measles and an accordingly low efficiency of transplacental transmission to a fetus. Current vaccination programs, which target children aged 8 months through adolescence may be ineffective in controlling transmission of measles to infants. © The Author 2017.

  2. A population screening test for antibody to measles virus

    Friedman, M.G.

    1981-01-01

    In areas where sporadic cases of measles continue to occur in spite of vaccination programs, the availability of a simple screening test for determination of seropositivity to measles virus is desirable. A sensitive radioimmunoassay (RIA) screening test (ST) for the detection of IgG antibody to measles virus, based on a solid phase RIA, is described. The assays were performed on polyvinyl microtiter plates for which the RIAST requires only 5 μl of serum per subject. Antigen consisted of a sonicated extract of measles virus-infected Vero cells. Rabbit antihuman IgG specific for the Fc-segment of human IgG, labelled with 125 I, was used to detect human IgG bound to viral antigen. The basic RIA method was characterized by carrying out full titrations of sera of 53 healthy adults, 10 children, and 13 patients with measles-associated illness. These sera were also tested by the hemagglutination inhibition (HI) technique; most of the measles sera were also tested by complement fixation (CF). RIAST results (expressed as binding ratios) obtained for 52 healthy adults are compared with their RIA serum titers. Of the 200 sera of patients of various ages tested by the RIAST, 63 borderline sera were also tested by HI. The RIAST, which does not require serum treatment other than inactivation, proved to be more sensitive as an indicator of seropositivity than HI. Implications of the results and practical applications of the screening test are discussed. (author)

  3. Decline in measles mortality: nutrition, age at infection, or exposure?

    Aaby, Peter; Bukh, Jette; Lisse, Ida Maria; da Silva, Maria Clotilde

    1988-01-01

    The mortality from measles was studied in an urban area of Guinea-Bissau one year before and five years after the introduction of a vaccination programme. The years after the introduction of immunisation saw a decline in mortality among unvaccinated children with measles. This decline occurred despite a lower age at infection and an increasing prevalence of malnourished children. State of nutrition (weight for age) did not affect the outcome of measles infection. The incidence of isolated cases, however, increased in the period after the introduction of measles vaccination. As mortality was lower among these cases, diminished clustering explained some of the reduction in mortality. Comparison between the urban district and a rural area inhabited by the same ethnic group showed a lower age at infection, less clustering of cases, and lower case fatality ratios in the urban area. Endemic transmission of measles in urban districts leads to less clustering of cases, which may help explain the usually lower case fatality ratios in these areas. As measles vaccination increases herd immunity and diminishes clustering of cases, it may reduce mortality even among unvaccinated children who contract the disease. PMID:3133023

    Full Text Available INTRODUCTION: The European Regional Office of the World Health Organization developed a strategic approach to stop the indigenous transmission of measles in its 53 Member States by 2015. In Italy, laboratory surveillance activity is implemented by the National Reference Laboratory for Measles and Rubella at the Italian National Institute of Health (Istituto Superiore di Sanità, Rome. The role of the National Reference Laboratory is to strengthen surveillance systems through rigorous case investigation and laboratory confirmation of suspected sporadic cases and outbreaks. Genetic characterization of wild-type measles virus is an essential component of the laboratory-based surveillance. This study describes the molecular characterization of measles virus strains isolated during 2010. METHODS: Dried blood spots, urine and oral fluid samples were collected from patients with a suspected measles infection. Serological tests were performed on capillary blood, and viral detection was performed on urine and oral fluid samples through molecular assay. Positive samples were sequenced and phylogenetically analysed. RESULTS AND DISCUSSION: The phylogenetic analysis showed a co-circulation of genotypes D4 and D8, and sporadic cases associated to genotypes D9 and B3. Then, molecular epidemiology of measles cases permitted to establish that D4 and D8 were the endemic genotypes in Italy during 2010.

  5. Achieving nanoscale horizontal separations in the standard 2 μm PolyMUMPS process

    Elshurafa, Amro M.

    2013-01-25

    This paper shares with the research community how to achieve, effectively and easily, lateral submicron separations in the standard 2 lm PolyMUMPS process without any fabrication intervention or post-processing, based on the oxide sidewall spacer technique. Thousands of nanoseparations were created and successfully tested by visual inspection and by a simple capacitance measurement. The lateral separations attained were less than 440 nm and reached as low as 280 nm. To corroborate the findings, measurements were performed on different capacitors fabricated in different fabrication runs with consistent results. This is the first time that submicron lateral distances are reported in PolyMUMPS using the oxide spacer technique.

    In Japan, mumps immunization is not mandatory, and the prevalence of mumps immunization among eligible children is only about 30%, raising concerns about increased risk of meningitis, encephalitis and deafness caused by mumps. In 2011, to understand why families are not voluntarily immunizing their children against mumps, we surveyed mothers who were university graduates to examine the factors and barriers influencing mumps vaccination in Japan. A cross sectional design. We sent questionnaires including questions on demographic data and vaccination status, barriers and factors for immunizations to university alumnae to recruit participants. Data were analysed by Student's t-test for continuous variables and by univariate and multivariate analysis to obtain the odds ratio and adjusted odds ratio. Two hundred and twenty-six mothers with children responded with an average (range) age of 44.7 years (SD = 5.02; 30-55 years). Adjusted odds ratios (aOR) from logistic regression analysis identified fear of harmful side-effects (aOR, 2.55; 95% CI, 1.10 to 5.89), the vaccination not being mandatory (aOR, 3.30; 95% CI, 1.41 to 7.72), perceived non-efficacy (aOR, 6.21; 95% CI, 1.85 to 20.91) and being busy (aOR, 3.30; 95% CI, 1.21 to 9.01) were significantly and inversely associated with mumps vaccination. Recommendations from family doctors (aOR, 0.35; 95% CI, 0.17 to 0.71), living abroad when their children would be vaccinated (aOR, 0.10; 95% CI, 0.02 to 0.68) and the maternal age (aOR, 0.91; 95% CI, 0.85 to 0.96) were significant and positively associated with vaccination. In the absence of mandatory vaccinations, a public education campaign about mumps, their potential consequences and the nature and value of vaccination could improve the prevalence of mumps vaccination among children and prevent the consequences of this disease.

    We document the MRI features in six patients aged 5-14 years with acute encephalitis following measles. The diagnosis was made on a characteristic morbiliform rash and detection of specific IgM and IgG antibodies. The symptoms of encephalitis occurred 1-11 days after the appearance of the rash. All patients underwent MRI within 1-4 days of the onset of neurological symptoms. Diffusion weighted images (DWI) were obtained in three patients. In all patients, T2-weighted images showed widely distributed, multifocal high signal in both cerebral hemispheres with swelling of the cortex, with bilateral, symmetrical involvement of the putamen and caudate nucleus. The lesions had showed low apparent diffusion coefficients. Three patients showed subacute gyriform haemorrhage, and asymmetrical gyriform contrast enhancement on follow-up MRI. (orig.)

    The measles epidemic was rather severe in Wujin 2015, and a seroprevalence survey of measles antibody was conducted during June to September 2015 in Wjin district of Changzhou city. Blood samples were collected from community health population and convenient samples of residual blood from hospitals. Measles-specific IgG levels were measured by ELISA assay. A total of 122 measles cases were reported 2015 in Wujin district with an incidence of 8.31 per 100000 populations. A large proportion of measles cases were adults ≥20years (62.30%) and infants aged measles were 82.71% and 551.19mIU/ml, respectively. Although the seroprevalence among children aged 9months to 4years was consistently over 90%, it began to decrease since 24months, and till the age of ≥10years, the seroprevalences were all measles and GMT levels between genders. The seroprevalence and GMT in people with measles vaccination were higher than those without measles vaccination or people whose measles vaccination are unknown (Pmeasles cases have become a serious problem in Wujin district, which may mainly relate to the increasing size of the floating population with low measles vaccine coverage. The seroprevalence of measles decreased dramatically with increasing age since teenagers, which may mainly caused by waning vaccine-induced immunity. Therefore, it is necessary to strengthen measles vaccine in these people especially floating population. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Measles control efforts are hindered by challenges in sustaining high vaccination coverage, waning immunity in HIV-1-infected children, and clustering of susceptible individuals. Our aim was to assess population immunity to measles virus after a mass vaccination campaign in a region with high HIV prevalence. 3 years after a measles supplemental immunisation activity (SIA), we undertook a cross-sectional survey in Lusaka, Zambia. Households were randomly selected from a satellite image. Children aged 9 months to 5 years from selected households were eligible for enrolment. A questionnaire was administered to the children's caregivers to obtain information about measles vaccination history and history of measles. Oral fluid samples were obtained from children and tested for antibodies to measles virus and HIV-1 by EIA. 1015 children from 668 residences provided adequate specimens. 853 (84%) children had a history of measles vaccination according to either caregiver report or immunisation card. 679 children (67%) had antibodies to measles virus, and 64 (6%) children had antibodies to HIV-1. Children with antibodies to HIV-1 were as likely to have no history of measles vaccination as those without antibodies to HIV-1 (odds ratio [OR] 1.17, 95% CI 0.57-2.41). Children without measles antibodies were more likely to have never received measles vaccine than those with antibodies (adjusted OR 2.50, 1.69-3.71). In vaccinated children, 33 (61%) of 54 children with antibodies to HIV-1 also had antibodies to measles virus, compared with 568 (71%) of 796 children without antibodies to HIV-1 (p=0.1). 3 years after an SIA, population immunity to measles was insufficient to interrupt measles virus transmission. The use of oral fluid and satellite images for sampling are potential methods to assess population immunity and the timing of SIAs.

  10. A chimeric measles virus with canine distemper envelope protects ferrets from lethal distemper challenge.

    2009-08-06

    CDV infects a broad range of carnivores, and over the past decades it has caused outbreaks in a variety of wild carnivore populations. Since the currently available live-attenuated vaccine is not sufficiently safe in these highly susceptible species, we produced a chimeric virus combining the replication complex of the measles Moraten vaccine strain with the envelope of a recent CDV wild type isolate. The resulting virus did not cause disease or immunosuppression in ferrets and conferred protection from challenge with a lethal wild type strain, demonstrating its potential value for wildlife conservation efforts.

    Background The genetic characterization of wild-type measles viruses plays an important role in the description of viral transmission pathways and the verification of measles elimination. The 450 nucleotides that encode the carboxyl-terminus of the nucleoprotein (N-450) are routinely sequenced for genotype analysis. Objectives The objectives of this study were to develop improved primers and controls for RT-PCR reactions used for genotyping of measles samples and to develop a method to provide a convenient, safe, and inexpensive means to distribute measles RNA for RT-PCR assays and practice panels. Study design A newly designed, genetically defined synthetic RNA and RNA isolated from cells infected with currently circulating genotypes were used to compare the sensitivity of primer pairs in RT-PCR and nested PCR. FTA® cards loaded with lysates of measles infected cells were tested for their ability to preserve viral RNA and destroy virus infectivity. Results A new primer pair, MeV216/MeV214, was able to amplify N-450 from viruses representing 10 currently circulating genotypes and a genotype A vaccine strain and demonstrated 100-fold increased sensitivity compared to the previously used primer set. A nested PCR assay further increased the sensitivity of detection from patient samples. A synthetic positive control RNA was developed that produced PCR products that are distinguishable by size from PCR products amplified from clinical samples. FTA® cards completely inactivated measles virus and stabilized RNA for at least six months. Conclusions These improved molecular tools will advance molecular characterization of circulating measles viruses globally and provide enhanced quality control measures. PMID:23806666

  14. A Global Perspective of Vaccination of Healthcare Personnel against Measles: Systematic Review

    Fiebelkorn, Amy Parker; Seward, Jane F.; Orenstein, Walter

    2015-01-01

    Measles transmission has been well documented in healthcare facilities. Healthcare personnel who are unvaccinated and who lack other evidence of measles immunity put themselves and their patients at risk for measles. We conducted a systematic literature review of measles vaccination policies and their implementation in healthcare personnel, measles seroprevalence among healthcare personnel, measles transmission and disease burden in healthcare settings, and impact/costs incurred by healthcare facilities for healthcare-associated measles transmission. Five database searches yielded 135 relevant articles; 47 additional articles were found through cross-referencing. The risk of acquiring measles is estimated to be 2 to 19 times higher for susceptible healthcare personnel than for the general population. Fifty-three articles published worldwide during 1989–2013 reported measles transmission from patients to healthcare personnel; many of the healthcare personnel were unvaccinated or had unknown vaccination status. Eighteen articles published worldwide during 1982–2013 described examples of transmission from healthcare personnel to patients or to other healthcare personnel. Half of European countries have no measles vaccine policies for healthcare personnel. There is no global policy recommendation for the vaccination of healthcare personnel against measles. Even in countries such as the United States or Finland that have national policies, the recommendations are not uniformly implemented in healthcare facilities. Measles serosusceptibility in healthcare personnel varied widely across studies (median 6.5%, range 0%-46%) but was consistently higher among younger healthcare personnel. Deficiencies in documentation of two doses of measles vaccination or other evidence of immunity among healthcare personnel presents challenges in responding to measles exposures in healthcare settings. Evaluating and containing exposures and outbreaks in healthcare settings can be

    The analysis of measles and rubella morbidity, the state of their vaccination in Ukraine was carried out. Despite decades of preventive vaccination, there is a 5-6 years’ cyclicity of measles epidemic process at present time. Measles morbidity increased 46.8 times in 2017 in comparison with 2016. Elevated rates of rubella epidemic morbidity were registered in 2004 and 2011. There was decrease of routine measles and rubella immunization coverage in the period from 2009 to 2016.

  16. Correlation of genetic variability with safety of mumps vaccine Urabe AM9 strain.

    Amexis, G; Fineschi, N; Chumakov, K

    2001-08-15

    The Urabe AM9 strain of mumps vaccine live is known for its genetic instability and some vaccines derived from this strain were withdrawn from the market due to an excessive number of vaccine-associated parotitis and meningitis cases. To identify the molecular basis of this instability, we determined complete nucleotide sequences of several stocks of the Urabe strain used for vaccine production by different manufacturers and of two clinical isolates from cases of vaccine-associated meningitis. In contrast to previously published studies relating the Lys335 --> Glu mutation in the viral HN gene with neurovirulence of mumps virus, we could not confirm any association of this mutation with the safety of mumps vaccine. Each of the three vaccine stocks studied had its own characteristic profile of mutations that was identified by cDNA sequencing and quantitated by mutant analysis by PCR and restriction enzyme cleavage. Determination of the mutational profile of mumps vaccine lots could allow vaccine manufacturers to characterize seed viruses and monitor the consistency of vaccine production to prevent emergence of virulent revertants.

  18. Meeting measles elimination indicators: surveillance performance in a regional area of Australia

    David N Durrheim

    2011-08-01

    Full Text Available The World Health Organization (WHO Western Pacific Region has established specific measles elimination surveillance indicators. There has been concern in Australia that these indicators may be too stringent and that measles elimination can occur without all surveillance prerequisites being met, in particular the minimum fever and rash clinician-suspected measles reporting rate with subsequent laboratory exclusion of measles. A regional public health unit in northern New South Wales, Australia, prompted local general practitioners to report fever and rash presentations that met the measles case definition or that they considered to be clinical measles. These notifications from July 2006 to June 2008 were reviewed to determine whether measles indicators for monitoring progress towards measles elimination could be achieved in Australia. Results confirmed that the surveillance indicators of “>2 reported suspected measles cases per 100 000 population,” “at least 80% of suspected cases adequately investigated within 48 hours” and “greater than 80% of cases had adequate blood samples collected” could be met. Only half the cases had virology that would allow genotyping of measles virus. Special efforts to engage and convince Australian medical doctors about the public health value of reporting clinically suggestive measles cases and collecting confirmatory blood tests, resulted in the current WHO Western Pacific Region indicators for progress towards measles elimination being met in a regional area of Australia.

    To compare the differences in the complete genome sequence between mumps epidemic strain and mumps vaccine strain S79 isolated in Zhejiang province. A total of 4 mumps epidemic strains, which were separated from Zhejiang province during 2005 to 2010, named as ZJ05-1, ZJ06-3, ZJ08-1 and ZJ10-1 were selected in the study. The complete genome sequences were amplified using RT-PCR. The genetic differences between vaccine strain S79 and other genotype strains were compared; while the genetic-distance was calculated and the evolution was analyzed. The biggest difference between the 4 epidemic strains and the vaccine strain S79 was found on the membrane associated protein gene; whose average nucleotide differential number was 42.5 +/- 3.0 and the average variant ratio was 13.6%; while the mean amino acid differential number was 12.8 +/- 1.5 and the average variant ratio was 22.4%. The smallest difference among the 4 epidemic strains and the vaccine strain was found in stromatin genes, whose average nucleotide differential number was 73.8 +/- 2.5 and the average variant ratio was 5.9%; while the mean amino acid differential number was 3.0 +/- 0.8 and the average variant ratio was 0.8%. The dn/ds value of the stromatin genes of the 4 epidemic strains reached the highest, as 0.6526; but without any positive pressure (dn/ds 0.05). There were mutations happened on the known antigen epitope, as 8th amino acid of membrane associated protein genes and on the 336th and 356th amino acid of hemagglutinin/neuraminidase proteins. Compared with the vaccine strain, the glycosylation sites of ZJ05-1, ZJ06-3, ZJ08-1 and ZJ10-1 increased 1, 1, 2 and 2 respectively. The complete amino acid sequence of all strains showed that there were 17 characteristic sites found on the genotype-F mumps strain. Within the complete genome, the genetic-distance between epidemic strains and vaccine strains in Zhejiang province (0.071) was significantly larger than the genetic-distance between strains in

    The objective of this study is primarily to compare the performance of the VIDAS® Measles immunoglobulin (Ig)G assay to that of two other serological assays using an immunoassay technique, Enzygnost® Anti-measles Virus/IgG (Siemens) and Measles IgG CAPTURE EIA® (Microimmune). The sensitivity and the agreement of the VIDAS® Measles IgG assay compared to the Enzygnost® Anti-measles Virus/IgG assay and the Measles IgG CAPTURE EIA® assay are 100%, 97.2% and 99.0%, 98.4%, respectively. The very low number of negative sera for IgG antibodies does not allow calculation of specificity. As a secondary objective, we have evaluated the ability of the VIDAS® Measles IgG assay to measure anti-measles virus IgG antibody avidity with the help of the VIDAS® CMV IgG Avidity reagent, using 76 sera from subjects with measles and 238 other sera. Different groups of populations were analyzed. In the primary infection measles group, the mean IgG avidity index was 0.16 (range of 0.07 to 0.93) compared to 0.79 (range of 0.25 to 1) in the serum group positive for IgG antibodies and negative for IgM. These data allow to define a weak anti-measles virus IgG antibody avidity as an avidity index (AI) 0.6. The VIDAS® Measles IgG assay has a performance equivalent to that of other available products. Its use, individual and quick, is well adapted to testing for anti-measles immunity in exposed subjects. PMID:27556477

  1. Measles vaccine: a 27-year follow-up.

    Ramsay, M E

    1994-04-01

    In 1964, the Medical Research Council undertook a trial of measles vaccine in over 36,000 United Kingdom children; 9577 of whom received live vaccine, 10,625 received inactivated followed by live vaccines, and 16,328 acted as unvaccinated controls. Participants in this study have been followed to determine the long term protection from measles vaccine and follow-up data were available on 4194, 4638 and 274 respectively. During the 5-year period 1986-90, the protective efficacy of live measles vaccine has remained high at 87%, but the 95% confidence interval was wide (-43 to 99%) due to the small numbers of cases. Between 1976 and 1990, however, the overall efficacy of the live vaccine was 92% (95% confidence interval 86 to 95%) and there was no evidence of a decline in efficacy (P = 0.13) over the 15-year period. This study suggests that the protection from live measles vaccine persists for up to 27 years after vaccination, and that no change in the current United Kingdom measles immunization policy should be made on the grounds of waning immunity.

    Whole-cell pertussis (wP) and measles vaccines are effective in preventing disease but have also been suspected of increasing the risk of encephalopathy or encephalitis. Although many countries now use acellular pertussis vaccines, wP vaccine is still widely used in the developing world. It is therefore important to evaluate whether wP vaccine increases the risk of neurologic disorders. A retrospective case-control study was performed at 4 health maintenance organizations. Records from January 1, 1981, through December 31, 1995, were examined to identify children aged 0 to 6 years old hospitalized with encephalopathy or related conditions. The cause of the encephalopathy was categorized as known, unknown or suspected but unconfirmed. Up to 3 controls were matched to each case. Conditional logistic regression was used to analyze the relative risk of encephalopathy after vaccination with diphtheria-tetanus-pertussis (DTP) or measles-mumps-rubella (MMR) vaccines in the 90 days before disease onset as defined by chart review compared with an equivalent period among controls indexed by matching on case onset date. Four-hundred fifty-two cases were identified. Cases were no more likely than controls to have received either vaccine during the 90 days before disease onset. When encephalopathies of known etiology were excluded, the odds ratio for case children having received DTP within 7 days before onset of disease was 1.22 (95% confidence interval [CI] = 0.45-3.31, P = 0.693) compared with control children. For MMR in the 90 days before onset of encephalopathy, the odds ratio was 1.23 (95% confidence interval = 0.51-2.98, P = 0.647). In this study of more than 2 million children, DTP and MMR vaccines were not associated with an increased risk of encephalopathy after vaccination.

  5. Reverse genetics of measles virus and resulting multivalent recombinant vaccines: applications of recombinant measles viruses.

    Billeter, M A; Naim, H Y; Udem, S A

    2009-01-01

    An overview is given on the development of technologies to allow reverse genetics of RNA viruses, i.e., the rescue of viruses from cDNA, with emphasis on nonsegmented negative-strand RNA viruses (Mononegavirales), as exemplified for measles virus (MV). Primarily, these technologies allowed site-directed mutagenesis, enabling important insights into a variety of aspects of the biology of these viruses. Concomitantly, foreign coding sequences were inserted to (a) allow localization of virus replication in vivo through marker gene expression, (b) develop candidate multivalent vaccines against measles and other pathogens, and (c) create candidate oncolytic viruses. The vector use of these viruses was experimentally encouraged by the pronounced genetic stability of the recombinants unexpected for RNA viruses, and by the high load of insertable genetic material, in excess of 6 kb. The known assets, such as the small genome size of the vector in comparison to DNA viruses proposed as vectors, the extensive clinical experience of attenuated MV as vaccine with a proven record of high safety and efficacy, and the low production cost per vaccination dose are thus favorably complemented.

    2009-12-01

    The present study was conducted over a period of one year to find the right time for measles vaccination when maternal antibody titer in infants was decayed rendering them susceptible to wild virus infection. Blood samples were collected from the cord of new born (147), 2-5 months (47) and 5 to 7.5 months (24) of age. The mean measles IgG antibody titer detected in cord blood at birth (0 months) was 348.8 mlU/mL which steeply decreased to 155.6 mlU/mL by the age of 2-3 months. After that the fall in antibody becomes relatively slower and decreased to 101.6 mIU/mL by the age of 3-5 months and 38.8 mlU/mL by the age of 5-6 months and to 19.2 mIU/mL between the age of 6 to 7.5 months. The fall in antibody level with the advance of age was statistically significant (p < 0.001 ). Majority of the subjects (97.6%) exhibited protective level of antibody at birth. But only a little above one-quarter (25.5%) of them persisted the protective level between the age of 2-5 months and none had protective level from 5 months onwards.

    Full Text Available Abstract Background Achieving equity means increased uptake of health services for those who need it most. But the poorest families continue to have the poorest service. In Pakistan, large numbers of children do not access vaccination against measles despite the national government's effort to achieve universal coverage. Methods A cross-sectional study of a random sample of 23 rural and 9 urban communities in the Lasbela district of south Pakistan, explored knowledge, attitudes and discussion around measles vaccination. Several socioeconomic variables allowed examination of the role of inequities in vaccination uptake; 2479 mothers provided information about 4007 children aged 10 to 59 months. A Mantel-Haenszel stratification analysis, with and without adjustment for clustering, clarified determinants of measles vaccination in urban and rural areas. Results A high proportion of mothers had appropriate knowledge of and positive attitudes to vaccination; many discussed vaccination, but only one half of children aged 10-59 months accessed vaccination. In urban areas, having an educated mother, discussing vaccinations, having correct knowledge about vaccinations, living in a community with a government vaccination facility within 5 km, and living in houses with better roofs were associated with vaccination uptake after adjusting for the effect of each of these variables and for clustering; maternal education was an equity factor even among those with good access. In rural areas, the combination of roof quality and access (vaccination post within 5 km along with discussion about vaccines and knowledge about vaccines had an effect on uptake. Conclusion Stagnating rates of vaccination coverage may be related to increasing inequities. A hopeful finding is that discussion about vaccines and knowledge about vaccines had a positive effect that was independent of the negative effect of inequity - in both urban and rural areas. At least as a short term

  9. Assessing age-dependent susceptibility to measles in Japan.

    Kinoshita, Ryo; Nishiura, Hiroshi

    2017-06-05

    Routine vaccination against measles in Japan started in 1978. Whereas measles elimination was verified in 2015, multiple chains of measles transmission were observed in 2016. We aimed to reconstruct the age-dependent susceptibility to measles in Japan so that future vaccination strategies can be elucidated. An epidemiological model was used to quantify the age-dependent immune fraction using datasets of vaccination coverage and seroepidemiological survey. The second dose was interpreted in two different scenarios, i.e., booster and random shots. The effective reproduction number, the average number of secondary cases generated by a single infected individual, and the age at infection were explored using the age-dependent transmission model and the next generation matrix. While the herd immunity threshold of measles likely ranges from 90% to 95%, assuming that the basic reproductive number ranges from 10 to 20, the estimated immune fraction in Japan was below those thresholds in 2016, despite the fact that the estimates were above 80% for all ages. If the second dose completely acted as the booster shot, a proportion immune above 90% was achieved only among those aged 5years or below in 2016. Alternatively, if the second dose was randomly distributed regardless of primary vaccination status, a proportion immune over 90% was achieved among those aged below 25years. The effective reproduction number was estimated to range from 1.50 to 3.01 and from 1.50 to 3.00, respectively, for scenarios 1 and 2 in 2016; if the current vaccination schedule were continued, the reproduction number is projected to range from 1.50 to 3.01 and 1.39 to 2.78, respectively, in 2025. Japan continues to be prone to imported cases of measles. Supplementary vaccination among adults aged 20-49years would be effective if the chains of transmission continue to be observed in that age group. Copyright © 2017 Elsevier Ltd. All rights reserved.

  10. Measles immune suppression: lessons from the macaque model.

    Rory D de Vries

    Full Text Available Measles remains a significant childhood disease, and is associated with a transient immune suppression. Paradoxically, measles virus (MV infection also induces robust MV-specific immune responses. Current hypotheses for the mechanism underlying measles immune suppression focus on functional impairment of lymphocytes or antigen-presenting cells, caused by infection with or exposure to MV. We have generated stable recombinant MVs that express enhanced green fluorescent protein, and remain virulent in non-human primates. By performing a comprehensive study of virological, immunological, hematological and histopathological observations made in animals euthanized at different time points after MV infection, we developed a model explaining measles immune suppression which fits with the "measles paradox". Here we show that MV preferentially infects CD45RA(- memory T-lymphocytes and follicular B-lymphocytes, resulting in high infection levels in these populations. After the peak of viremia MV-infected lymphocytes were cleared within days, followed by immune activation and lymph node enlargement. During this period tuberculin-specific T-lymphocyte responses disappeared, whilst strong MV-specific T-lymphocyte responses emerged. Histopathological analysis of lymphoid tissues showed lymphocyte depletion in the B- and T-cell areas in the absence of apoptotic cells, paralleled by infiltration of T-lymphocytes into B-cell follicles and reappearance of proliferating cells. Our findings indicate an immune-mediated clearance of MV-infected CD45RA(- memory T-lymphocytes and follicular B-lymphocytes, which causes temporary immunological amnesia. The rapid oligoclonal expansion of MV-specific lymphocytes and bystander cells masks this depletion, explaining the short duration of measles lymphopenia yet long duration of immune suppression.

    Despite enormous challenges, Somalia has been successfully implementing accelerated measles control activities since 2005. Through innovative strategies and with the support of local and international partners, the country has shown potentials of implementing measles mortality reduction activities in complex emergencies. Measles incidence has been reduced by >80% after the measles catch-up campaigns of 2005-2007, and national reported measles routine immunization coverage with first dose measles containing vaccine has reached 59% for the first time in 2009. However, the near collapse of the health care system and the ongoing insecurity continue to hamper the implementation of recommended measles control and elimination strategies in some parts of the country, making these achievements fragile. Somalia exemplifies the challenges in meeting measles elimination goals in the World Health Organization Eastern Mediterranean region. As the region is entering its 2010 measles elimination goals, it appears necessary to establish realistic and flexible interim goals for measles control in Somalia that will take into consideration the specificities of the country. Maintaining flexibility in conducting field operations, securing financial resources, multiplying opportunities for measles vaccination, and improving disease monitoring systems will remain vital to sustain and improve current achievements. © The Author 2011.

  13. Seroprevalence of mumps in The Netherlands: dynamics over a decade with high vaccination coverage and recent outbreaks.

    Gaby Smits

    Full Text Available Here we present mumps virus specific antibody levels in a large cross-sectional population-based serosurveillance study performed in the Netherlands in 2006/2007 (n = 7900. Results were compared with a similar study (1995/1996 and discussed in the light of recent outbreaks. Mumps antibodies were tested using a fluorescent bead-based multiplex immunoassay. Overall seroprevalence was 90.9% with higher levels in the naturally infected cohorts compared with vaccinated cohorts. Mumps virus vaccinations at 14 months and 9 years resulted in an increased seroprevalence and antibody concentration. The second vaccination seemed to be important in acquiring stable mumps antibody levels in the long term. In conclusion, the Dutch population is well protected against mumps virus infection. However, we identified specific age- and population groups at increased risk of mumps infection. Indeed, in 2007/2008 an outbreak has occurred in the low vaccination coverage groups emphasizing the predictive value of serosurveillance studies.

    As China approaches the elimination of measles, outbreaks of measles continue to occur. Healthcare workers (HCWs) are known to be at high risk of infection and transmission of measles virus. A measles outbreak occurred in a hospital in Xinjiang Uighur Autonomous Region of the People's Republic of China. We report an investigation of this outbreak and its implications for measles elimination and outbreak preparedness. We conducted a retrospective search for measles cases using hospital records. Information on cases was collected by interview, and was used to determine epidemiological linkages. We surveyed HCWs to determine their demographic characteristics, disease history and vaccination status, and knowledge about measles. We identified 19 cases, ages 18 to 45 years, in Hospital W between December 2015 and January 2016; 14 were laboratory-confirmed, and 5 were epidemiologically linked. The primary case was a 25-year-old neurology department nurse who developed a rash on 22 December 2015 that was reported on 11 January 2016. She continued working and living with her workmates in a dormitory during her measles transmission period. Among the 19 infected HCWs, 2 had received a dose of measles-containing vaccine (MCV) before the outbreak, and 16 had unknown vaccination status. Outbreak response immunization activities were started on 8 January in a non-selective manner by offering vaccine regardless of vaccination history; 605(68%) of 890 HCWs were vaccinated. The HCW survey had a 73% response rate (646/890); 41% of HCWs reported that they had received MCV before outbreak, and 56% exhibited good knowledge of measles symptoms, transmission, complications, and vaccination. Low MCV coverage, low measles knowledge among HCWs, delayed reporting of measles cases, and absence of proper case management were associated with this outbreak. Training and vaccinating HCWs against measles are essential activities to prevent measles virus transmission among HCWs.

    2017-07-03

    On 18 August 2015, Kyegegwa District reported eight deaths during a measles outbreak to the Uganda Ministry of Health (MoH). We investigated this death cluster to verify the cause, identify risk factors, and inform public health interventions. We defined a probable measles case as onset of fever and generalised rash in a Kyegegwa District resident from 1 February - 15 September 2015, plus ≥1 of the following: coryza, conjunctivitis, and cough. A confirmed measles case was a probable case with measles-specific IgM positivity. A measles death was a death of a probable or confirmed case-person. We conducted an active case-finding to identify measles patients who survived or died. In a case-control study, we compared risk factors between 16 measles patients who died (cases) and 48 who survived (controls), matched by age (±4 years) and village of residence. We identified 94 probable measles cases, 10 (11%) were confirmed by positive measles-specific IgM. Of the 64 probable measles patients aged measles was found in 94% (15/16) among the case-persons (i.e., measles patients who died) and 54% (26/48) among the controls (i.e., measles patients who survived) (OR M-H  = 12; 95% CI = 1.6-104), while 56% (9/16) of case-persons and 67% (17/48) of controls (OR M-H  = 2.3; 95% CI =0.74-7.4) did not receive vitamin A supplementation during illness. 63% (10/16) among the case-persons and 6.3% (3/48) of the controls (OR M-H  = 33; 95% CI = 6.8-159) were not treated for measles illness at a health facility (a proxy for more appropriate treatment), while 38% (6/16) of the case-persons and 25% (12/48) of the controls (OR M-H  = 2.5; 95% CI = 0.67-9.1) were malnourished. Lack of vaccination and no treatment in a health facility increased the risk for measles deaths. The one-dose measles vaccination currently in the national vaccination schedule had a protective effect against measles death. We recommended enhancing measles vaccination and adherence to measles treatment

    Full Text Available Meningococcal infection is an acute disease caused by Neisseria meningitidis, which proceeds with a diverse clinical aspect from nasopharyngitis to meningococcal meningitis and meningococcemia. Since 2014, a tetravalent meningococcal conjugate vaccine has been registered in Russia. This vaccine creates protection against serogroups A, C, W-135, Y and can be used from the age of nine months to 55 years. The actual issue is a vaccine tolerability, including when combined with other vaccine preparations.Objective: Our aim was to evaluate the safety of a tetravalent meningococcal conjugate vaccine against serogroups A, C, Y and W-135 when it is combined with other vaccine preparations.Methods. A prospective full-design study assessed the tolerability of immunization with a meningococcal conjugate vaccine, both in case of monovaccination and in combination with a pneumococcal 13-valent conjugate vaccine, measles-mumps-rubella, viral hepatitis A, influenza, and chicken pox vaccines.Results. 97 children aged from 9 months to 18 years were vaccinated, 20 of them were healthy and 77 had medical issues (with allergic pathology, ENT diseases, cardiovascular and nervous system diseases, lung diseases as well as orphan diseases. Among vaccinated children, general reactions were observed in 3/97 (3.1% children, local reactions — in 5 (5.2%. The post-vaccination period passed asymptomatically and uneventfully in the prevailing majority of children vaccinated with a tetravalent meningococcal conjugate vaccine (in 91, 93.8%.Conclusion. The immunization with a tetravalent meningococcal conjugate vaccine against serogroups A, C, Y, W-135 is well tolerated, both in case of monovaccination and in combination with other vaccine preparations, in healthy children of different age groups and in patients with different health status.

  17. Measles IgG antibody index correlates with T2 lesion load on MRI in patients with early multiple sclerosis.

    Berit Rosche

    Full Text Available BACKGROUND: B cells and humoral immune responses play an important role in the pathogenesis and diagnosis of multiple sclerosis (MS. A characteristic finding in patients with MS is a polyspecific intrathecal B cell response against neurotropic viruses, specifically against measles virus, rubella virus, and varicella zoster virus, also known as an MRZ reaction (MRZR. Here, we correlated from the routine clinical diagnostics individual IgG antibody indices (AIs of MRZR with magnetic resonance imaging (MRI findings in patients with first MS diagnosis. METHODS/RESULTS: MRZR was determined in 68 patients with a clinically isolated syndrome (CIS or early relapsing-remitting MS (RRMS. Absolute AI values for measles virus, rubella virus, and varicella zoster virus were correlated with T2 lesion load and gadolinium enhancing lesions on cerebral MRI (cMRI and cMRI combined with spinal MRI (sMRI. Measles virus AI correlated significantly with T2 lesion load on cMRI (p = 0.0312, Mann-Whitney U test and the sum of lesions on cMRI and sMRI (p = 0.0413. Varicella zoster virus AI also showed a correlation with T2 lesion load on cMRI but did not reach statistical significance (p = 0.2893. CONCLUSION: The results confirm MRZR as part of the polyspecific immune reaction in MS with possible prognostic impact on MRI and clinical parameters. Furthermore, the data indicate that intrathecal measles virus IgG production correlates with disease activity on cMRI and sMRI in patients with early MS.

    In 2012, an increase in mumps notifications occurred in Belgium, affecting young vaccinated adults. At the end of 2012, a mumps outbreak occurred at the Catholic University of Leuven KU Leuven in Flanders. We investigated the outbreak to estimate incidence, mumps vaccine effectiveness and to detect potential risk factors for the disease. In June 2012, we set up mandatory notification in Flanders and we collected information on circulating genotypes from the National Reference Centre. We conducted a cohort study among KU Leuven students. We defined a case as self-reported parotitis, between September 2012 and March 2013. We distributed web-based questionnaires to a random sample of students. We calculated vaccine effectiveness by comparing the risks in students vaccinated twice with those vaccinated once. We estimated risk ratios (RR) to identify risk factors. From 16th June 2012 to 1st April 2013, 4061 mumps cases were notified to the regional public health office (30% were vaccinated once and 69% were vaccinated twice). All 16 samples collected at the KU Leuven were genotype G5. Of 717 participants of the cohort study, 38 (5%; 95%CI 4-8%) met the case-definition. All reported being vaccinated with at least one dose of mumps-containing vaccine. The incidence of mumps was 5% among those vaccinated twice and 16% among those vaccinated once (vaccine effectiveness of two doses compared to one: 68%, 95%CI -24% to 92%). The risk of mumps was lower among those vaccinated with two doses of mumps-containing vaccine ≤10 years before (RR: 0.33, 95%CI 0.10-1.02) and higher among students working in a bar (RR: 3.6, 95%CI 1.8-7.0). Incomplete protection by two doses of mumps-containing vaccine, possible waning immunity and intense social contacts may have contributed to the occurrence of this outbreak in Flanders. Efforts to maintain high vaccination coverage with two doses remain essential. However, the reasons for low vaccine effectiveness must be further explored and

  19. Immunogenicity of mumps virus vaccine candidates matching circulating genotypes in the United States and China.

    Mumps virus (MuV) causes acute infection in humans with characteristic swelling of the parotid gland. While vaccination has greatly reduced the incidence of MuV infection, there have been multiple large outbreaks of mumps virus (MuV) in highly vaccinated populations. The most common vaccine strain, Jeryl Lynn, belongs to genotype A, which is no longer a circulating genotype. We have developed two vaccine candidates that match the circulating genotypes in the United States (genotype G) and China (genotype F). We found that there was a significant decrease in the ability of the Jeryl Lynn vaccine to produce neutralizing antibody responses to non-matched viruses, when compared to either of our vaccine candidates. Our data suggests that an updated vaccine may allow for better immunity against the circulating MuV genotypes G and F. Copyright © 2017 Elsevier Ltd. All rights reserved.

  20. Neurovirulence safety testing of mumps vaccines--historical perspective and current status.

    Rubin, S A; Afzal, M A

    2011-04-05

    Many live, attenuated viral vaccines are derived from wild type viruses with known neurovirulent properties. To assure the absence of residual neurotoxicity, pre-clinical neurovirulence safety testing of candidate vaccines is performed. For mumps virus, a highly neurotropic virus, neurovirulence safety testing is performed in monkeys. However, laboratory studies suggest an inability of this test to correctly discern among virus strains of varying neurovirulence potential in man, and, further, some vaccines found to be neuroattenuated in monkeys were later found to be neurovirulent in humans when administered in large numbers. Over the past decade, concerted efforts have been made to replace monkey-based neurovirulence safety testing with more informative, alternative methods. This review summarizes the current status of mumps vaccine neurovirulence safety testing and insights into models currently approved and those under development. Published by Elsevier Ltd.

    To develop a new live attenuated mumps vaccine, a wild mumps Y7 strain isolated from a patient who developed mild parotitis was treated with nitrosoguanidine and ultraviolet, followed by selection of a temperature-sensitive clone. The selected clone, Y125, showed stable temperature-sensitivity in Vero cells. Intraspinal inoculation of marmosets with the Y125 produced only minimal histopathological changes, while intracerebral inoculation of neonatal rats revealed that the Y125 did not cause hydrocephalus. Both these effects of the Y125 were similar to those of the non-neurovirulent Jeryl Lynn strain. Furthermore, subcutaneous inoculation of the Y125 induced high levels of neutralizing antibodies in all Cercopithecus monkeys examined. Although the safety and immunogenicity should be confirmed in further field trials in humans, the present results indicate that the Y125 could be a promising vaccine candidate.

  2. Distinct Contributions of Autophagy Receptors in Measles Virus Replication.

    Autophagy is a potent cell autonomous defense mechanism that engages the lysosomal pathway to fight intracellular pathogens. Several autophagy receptors can recognize invading pathogens in order to target them towards autophagy for their degradation after the fusion of pathogen-containing autophagosomes with lysosomes. However, numerous intracellular pathogens can avoid or exploit autophagy, among which is measles virus (MeV). This virus induces a complete autophagy flux, which is required to improve viral replication. We therefore asked how measles virus interferes with autophagy receptors during the course of infection. We report that in addition to NDP52/CALCOCO₂ and OPTINEURIN/OPTN, another autophagy receptor, namely T6BP/TAXIBP1, also regulates the maturation of autophagosomes by promoting their fusion with lysosomes, independently of any infection. Surprisingly, only two of these receptors, NDP52 and T6BP, impacted measles virus replication, although independently, and possibly through physical interaction with MeV proteins. Thus, our results suggest that a restricted set of autophagosomes is selectively exploited by measles virus to replicate in the course of infection.

  8. Measles mimicking HIV seroconversion syndrome: a case report

    Brook Gary

    2010-02-01

    Full Text Available Abstract Introduction Measles is on the rise in the United Kingdom and must be considered in the differential diagnosis of any patient presenting with fever and rash. As a highly infectious disease, identified patients must be isolated in the hospital setting. Case presentation A 28-year-old Polish woman presented ill to the accident and emergency department of a district general hospital. She had painful genital ulceration, oral soreness, fever, and a facial rash. She became hypoxic within 24 hours of presentation and began to tire, thus requiring noninvasive ventilation. Her respiratory symptoms were out of proportion to the findings of her chest radiograph, which remained virtually normal. Human immunodeficiency virus seroconversion syndrome complicated by Pneumocystis carinii pneumonia was high among the differential diagnoses. She was given cotrimoxazole, high-dose steroids, broad spectrum antibiotics, and anti fungal cover. Human immunodeficiency virus polymerase chain reaction came back as negative and her symptoms resolved within 10 days of presentation. She was taken off all treatment and discharged home feeling well. Serological measles was confirmed as part of a viral screen, but its clinical suspicion was low. Conclusion The presentation of measles in this patient was unique and atypical. With its incidence rising in the United Kingdom, measles must be increasingly considered as a differential diagnosis in patients presenting with fever and rash.

  19. [The knowledge of pediatricians in Salvador, Brazil about measles vaccine].

    Moreira, L A; Carvalho, F M; Silvany-Neto, A M; Peres, M F

    1997-12-01

    The success of international initiatives for the eradication of measles depends in large part on knowledge about vaccination. In 1992, a cross-sectional study was carried out to evaluate knowledge about measles vaccine among pediatricians in the Brazilian city of Salvador, Bahia. Of the 506 pediatricians residing in the city, 299 (59%) could be located and responded to a questionnaire containing 15 questions that posed hypothetical situations regarding indications and contraindications for this vaccine. The average number of correct responses was 9.3 out of 15, which illustrates the pediatricians' poor knowledge of measles vaccine. Conditions commonly seen in pediatric practice in Brazil--malnutrition, upper respiratory tract infection, diarrhea, and prematurity--were often erroneously considered contraindications for immunization. More than half (62%) of the pediatricians did not know the correct way to administer the vaccine. Knowledge about the vaccine did not differ according to the length of time that had elapsed since the physicians' university training in pediatrics or as a result of working in health centers operated by the State Health Secretariat. University professors, pediatricians with a postgraduate degree, and those pursuing postgraduate studies scored slightly higher than the rest. These results point to the need to strengthen training on measles vaccination in medical schools and programs of continuing education for pediatricians.

  2. A novel, polymer-coated oncolytic measles virus overcomes immune suppression and induces robust antitumor activity

    Kaname Nosaki

    2016-01-01

    Full Text Available Although various therapies are available to treat cancers, including surgery, chemotherapy, and radiotherapy, cancer has been the leading cause of death in Japan for the last 30 years, and new therapeutic modalities are urgently needed. As a new modality, there has recently been great interest in oncolytic virotherapy, with measles virus being a candidate virus expected to show strong antitumor effects. The efficacy of virotherapy, however, was strongly limited by the host immune response in previous clinical trials. To enhance and prolong the antitumor activity of virotherapy, we combined the use of two newly developed tools: the genetically engineered measles virus (MV-NPL and the multilayer virus-coating method of layer-by-layer deposition of ionic polymers. We compared the oncolytic effects of this polymer-coated MV-NPL with the naked MV-NPL, both in vitro and in vivo. In the presence of anti-MV neutralizing antibodies, the polymer-coated virus showed more enhanced oncolytic activity than did the naked MV-NPL in vitro. We also examined antitumor activities in virus-treated mice. Complement-dependent cytotoxicity and antitumor activities were higher in mice treated with polymer-coated MV-NPL than in mice treated with the naked virus. This novel, polymer-coated MV-NPL is promising for clinical cancer therapy in the future.

  3. Mumps in a district primary school at the locality of Santa Fe, Bogota (Colombia 2010.

    2010-12-01

    Full Text Available Background. Epidemic parotitis (“mumps” is a human viral infection which affects mainly the salivary glands; its peak incidence afflicts children 5 to 9-year. At epidemiologic week (EW 40/2010, the Centro Oriente II Level Hospital received a community report about a mumps outbreak in a District Primary School (DPS, eastwards of the locality of Santa Fe (Bogotá. The hospital’s epidemiology office sent a response team to investigate the situation and to guide prevention & control actions. Methods. The team made an outbreak descriptive study; field investigation included description time-place-person; case-definition as patient with active clinical condition of parotitis; Active Institutional Search (AIS and house visitations; study variables matched those of the official individual notification report. Data were registered and analyzed using Epi -Info 3.5.1® with frequency, central trend and association measurements. Results. 14 mumps cases were identified: 1 adult and 13(93% children; 5(35,7% were girls; median age was 11,9 year (range 7-40. Four cases (28,6% were confirmed by clinical signs, 10(71,4% by epidemiologic link; no one was hospitalized. 12 patients (86% had unknown vaccination status; 11 cases (78% produced neither the vaccination card nor any additional information. Index case occurred at EW30/2010 and the epidemic peak occurred at EW34/2010; attack rate was 8.1%. Conclusions. Epidemiology office confirmed mumps outbreak, delayed notification and impossibility to verify vaccination records. The response team recommended the DPS to strengthen biosafety measures; and advised local health institution to increase epidemiologic surveillance & control activities, adherence to national mumps protocol, school vaccination and to promote information, communication, education strategies on importance of vaccination and cards right use.

    Mumps, a communicable, acute and previously well-controlled disease, has had recent and occasional resurgences in some areas. A randomized, double-blind, controlled and multistep phase I study of an F-genotype attenuated mumps vaccine produced in human diploid cells was conducted. A total of 300 subjects were enrolled and divided into 4 age groups: 16-60 years, 5-16 years, 2-5 years and 8-24 months. The groups were immunized with one injection per subject. Three different doses of the F-genotype attenuated mumps vaccine, A (3.5 ± 0.25 logCCID50), B (4.25 ± 0.25 logCCID50) and C (5.0 ± 0.25 logCCID50), as well as a placebo control and a positive control of a licensed A-genotype vaccine (S79 strain) were used. The safety and immunogenicity of this vaccine were compared with those of the controls. The safety evaluation suggested that mild adverse reactions were observed in all groups. No serious adverse event (SAE) was reported throughout the trial. The immunogenicity test showed a similar seroconversion rate of the neutralizing and ELISA antibody in the 2- to 5-year-old and 8- to 24-month-old groups compared with the seroconversion rate in the positive control. The GMT of the neutralizing anti-F-genotype virus antibodies in the vaccine groups was slightly higher than that in the positive control group. The F-genotype attenuated mumps vaccine evaluated in this clinical trial was demonstrated to be safe and have effective immunogenicity vs. control.

    In the French national health insurance information system (SNIIR-AM), routine records of health claimed reimbursements are linked to hospital admissions for the whole French population. The main focus of this work is the usability of this system for vaccine safety assessment programme. Self-controlled case series analyses were performed using an exhaustive SNIIR-AM extraction of French children aged less than 3 years, to investigate the relationship between MMR immunization and children hospitalizations for febrile convulsions, a well-documented rare adverse event, over 2009-2010. The results suggest a significant increase of febrile convulsions during the 6-11 days period following any MMR immunization (IRR=1.49, 95% CI=1.22, 1.83; p=0.0001) and no increase 15-35 days post any MMR immunization (IRR=1.03, 95% CI=0.89, 1.18; p=0.72). These results are in accordance with other results obtained from large epidemiologic studies, which suggest the usability of the SNIIR-AM as a relevant database to study the occurrence of adverse events associated with immunization. For future use, results associated with risk of convulsion during the day of vaccination should nevertheless be considered with particular caution. Copyright © 2013 Elsevier Ltd.

    To investigate the relationship between mumps and the extent of hearing impairment and otolith organ damage. A total of 27 patients with unilateral hearing impairment following mumps were enrolled. The degrees of hearing loss and otolith organ damage were confirmed by audiometric and vestibular evoked myogenic potential [VEMP] tests. All the results were compared and analyzed using Stata 13.0 software for Windows. The VEMP thresholds of the affected ears were significantly higher than those of the unaffected ears in both tests (cervical VEMP [cVEMP] test and ocular VEMP [oVEMP] test; p = 0.000 and 0.001, respectively). The mean cVEMP and oVEMP threshold values of the affected ears with hearing impairment for ≤10 years were significantly lower than those of affected ears with hearing impairment for >10 years [p = 0.009 and 0.004, respectively]. Deafness resulting from mumps is usually profound and permanent, which indicates severe damage to the cochlea due to the disease. The functions of otolith organs in the vestibular system are also impaired. Over time, the function of the otolith organs or their neural pathway may suffer secondary damage.

    The purpose of this study was to investigate mumps vaccine failures (VF) in a highly vaccinated population of Minsk, Belarus, and to investigate a possible role for virus strain-specific immunity. During our 3-year study period, 22 adults were admitted to the Infectious Diseases Hospital in Minsk with a diagnosis of mumps. A genotype H1 mumps virus (MuV) strain was identified in all patients. Of 15 patients from whom the paired sera were collected, 9 were confirmed to have been previously vaccinated. Serological examinations indicated primary VF in seven of these cases and secondary VF in two. Despite almost all vaccinated patients possessing MuV specific IgG, few possessed neutralizing antibody to the vaccine strain and titers were nominal. Importantly, none of the sera were able to neutralize a genotype H MuV strain. Our results demonstrate the importance of assaying for neutralizing antibody and support the assertion that antigenic differences between wild type and vaccine MuV strains may play a role in cases of breakthrough infection in vaccinees.

    2013-06-01

    Aseptic meningitis and acute parotitis have been observed after mumps vaccination. Mumps outbreaks have been reported in Japan because of low vaccine coverage, and molecular differentiation is required to determine whether these cases are vaccine associated. RT-nested PCR was performed in the small hydrophobic gene region, and viruses were differentiated by restriction fragment length polymorphism assay. A total of 584 nucleotides were amplified. The PCR product of the Hoshino strain was cut into two fragments (313 and 271 nucleotides) by MfeI; that of the Torii strain was digested with EcoT22I, resulting in 332- and 252-nucleotide fragments. Both strains were genotype B and had an XbaI site, resulting in two fragments: 299 and 285 nucleotides. Current circulating wild types were cut only by XbaI or MfeI. However, the MfeI site of the wild types was different from that of the Hoshino strain, resulting in 451- and 133-nucleotide fragments. Using three restriction enzymes, two mumps vaccine strains were distinguished from wild types, and this separation was applied to the identification of vaccine-related adverse events.

    The purpose of this study was to determine the risk of aseptic meningitis after mumps vaccination in younger children compared with older children. This prospective cohort study included a total of 21,465 children under 18 years of age who had received the first dose of three of the Japanese mumps monovalent vaccine. We compared the cumulative incidence of aseptic meningitis for 30 days after vaccination among the following age groups: ≤ 1, 2, 3-4, and ≥ 5 years old. We also investigated the cumulative incidence of salivary gland swelling, a fever (≥ 38°C) lasting at least 3 days during the 10 to 25 days following immunization, vomiting of 3 times or more, headache, and seizure. A total of 10 aseptic meningitis, 551 salivary gland swelling, 844 fevers, 669 vomiting, 757 headaches, and 29 seizure cases were identified. The cumulative incidence of aseptic meningitis increased with age (0.016%, 0.021%, 0.066%, and 0.096%, respectively). Statistical significance was observed between children ≥ 3 years old and those mumps vaccine that is currently available for use in Japan may be administered in children less than 3 years of age in order to complicate a less aseptic meningitis after immunization.

    Full Text Available This paper presents a fully differential single-axis accelerometer fabricated using the MetalMUMPs process. The unique structural configuration and common-centriod wiring of the metal electrodes enables a fully differential sensing scheme with robust metal sensing structures. CoventorWare is used in structural and electrical design and simulation of the fully differential accelerometer. The MUMPs foundry fabrication process of the sensor allows for high yield, good process consistency and provides 20 μm structural thickness of the sensing element, which makes the capacitive sensing eligible. In device characterization, surface profile of the fabricated device is measured using a Veeco surface profilometer; and mean and gradient residual stress in the nickel structure are calculated as approximately 94.7 MPa and −5.27 MPa/μm, respectively. Dynamic characterization of the sensor is performed using a vibration shaker with a high-end commercial calibrating accelerometer as reference. The sensitivity of the sensor is measured as 0.52 mV/g prior to off-chip amplification. Temperature dependence of the sensing capacitance is also characterized. A −0.021fF/°C is observed. The findings in the presented work will provide useful information for design of sensors and actuators such as accelerometers, gyroscopes and electrothermal actuators that are to be fabricated using MetalMUMPs technology.

    We isolated 872 strains of mumps virus from naso-pharyngeal secretions in seven different districts of Japan from January 2000 to July 2001. Among them, 57 strains were geno-typed by nucleotide sequencing in part of the hemagglutinin-neuraminidase (HN) and small hydrophobic (SH) protein regions. Four different genotypes (B, G, K, and L) of mumps virus were co-circulating in Japan and the distribution of genotypes varied in geographically different districts. Two new clusters designated as genotypes K and L had more than 7% nucleotide variation in the SH gene. Among the 57 strains, 11 were classified as B, 35 as G, three as K, and eight as L, which was mainly isolated in Tokyo. We also examined 104 stains isolated in a clinic in Mie prefecture from 1993 to 2003. Genotype B was the indigenous strain and genotype K was introduced in 1994. Genotypes B and K co-circulated in the 1990s and were replaced by genotype G in 2000. There was no significant change in neutralizing test antibody titers against genotypes B, G, K, and L using seven post-vaccination sera with Hoshino strain (genotype B) and these four genotypes had a different antigenicity from genotype A. We should continue to watch on mumps virus molecular epidemiology. Copyright 2004 Wiley-Liss, Inc.

    In Korea, measles occurs mainly in infants measles infection. Age-specific measles seroprevalence was evaluated by performing enzyme immunoassays and plaque reduction-neutralization tests on 3050 subjects aged 0-50years (birth cohort 1964-2014) and 480 subjects aged 2-30years (birth cohort 1984-2012). The overall seropositivity and measles antibody concentrations were 71.5% and 1366mIU/mL, respectively. Progressive decline in antibody levels and seropositivity were observed over time after vaccination in infants, adolescents, and young adults. The accumulation of potentially susceptible individuals in the population was confirmed by comparing data from 2010 and 2014 seroprevalence surveys. The statistical correlation between measles incidence and measles seronegativity was determined. Waning levels of measles antibodies with increasing time post-vaccination suggests that measles susceptibility is potentially increasing in Korea. This trend may be related to limitations of vaccine-induced immunity in the absence of natural boosting by the wild virus, compared to naturally acquired immunity triggered by measles infection. This study provides an important view into the current measles herd immunity in Korea. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    ABSTRACT This study examined the epidemiological and serological characteristics of measles in Dongguan, China. From 2005 to 2014, a total of 8,224 measles cases were reported in Dongguan, 33.5% of which were aged 14 y. From 2005 to 2014, the proportion of the measles cases increased year by year from 24.3% to 47.9%. Of the cases aged ≥8 months (n = 6,768 cases), only 11.6% had been immunized with at least one dose of measles vaccine. Of the 2,213 cases who had never been immunized with measles vaccine, immigrants accounted for 82.4%. 52.4% of the measles cases were diagnosed with pneumonia, and 12 cases died from respiratory failure. Seroprevalence rate in women and their newborns was 86.0% and 82.5%, respectively. Measurement of serum measles antibody levels for infants aged less than 8 months indicated that seroprevalence rate dramatically declined from 97.3% at birth to 9.3% and 13.2% at 6- and 7- month old. The existence of a sufficient pool of unvaccinated people (especially immigrants) and decreased level of passively transferred measles antibodies in infants from vaccinated mothers contributed to the sustained transmission observed in Dongguan. In addition to high routine vaccination coverage, new strategies and innovations for measles vaccination are needed to eliminate measles. PMID:27003239

    To highlight the complications involved in interpreting laboratory tests of measles immunoglobulin M (IgM) for confirmation of infection during a measles outbreak in a highly vaccinated population after conducting a mass immunization campaign as a control measure. This case study was undertaken in the Republic of the Marshall Islands during a measles outbreak in 2003, when response immunization was conducted. A measles case was defined as fever and rash and one or more of cough, coryza or conjunctivitis. Between 13 July and 7 November 2003, serum samples were obtained from suspected measles cases for serologic testing and nasopharyngeal swabs were taken for viral isolation by reverse transcriptase polymerase chain reaction (RT-PCR). Specimens were collected from 201 suspected measles cases (19% of total): of the ones that satisfied the clinical case definition, 45% were IgM positive (IgM+) and, of these, 24% had received measles vaccination within the previous 45 days (up to 45 days after vaccination an IgM+ result could be due to either vaccination or wild-type measles infection). The proportion of IgM+ results varied with clinical presentation, the timing of specimen collection and vaccination status. Positive results on RT-PCR occurred in specimens from eight IgM-negative and four IgM+ individuals who had recently been vaccinated. During measles outbreaks, limiting IgM testing to individuals who meet the clinical case definition and have not been recently vaccinated allows for measles to be confirmed while conserving resources.

    Background: Despite substantial progress toward measles control are making in China, measles outbreaks in immunocompromised population still pose a challenge to interrupt endemic transmission. This study aimed to investigate the features of measles in pediatric hematology and oncology patients and explore the reasons behind the outbreak. Methods: We collected demographic, epidemiological, and clinical data of immunocompromised measles children. All suspected measles cases were laboratory-confirmed based on the presence of measles IgM and/or identification of measles RNA. The clinical data were statistically analyzed by t-test for continuous variables and Fisher's exact test for categorical variables. Results: From March 9 to July 25 in 2015, a total of 23 children with malignancies and post hematopoietic stem cell transplantation (post-HSCT) were notified to develop measles in Shanghai. Of these 23 patients with the median age of 5.5 years (range: 11 months–14 years), 20 (87.0%) had received 1–3 doses of measles vaccine previously; all patients had fever with the median fever duration of 8 days; 21 (91.3%) had cough; 18 (78.3%) had rash; 13 (56.5%) had Koplik's spot; 13 (56.5%) had complications including pneumonia and acute liver failure; and five (21.7%) vaccinated patients died from severe pneumonia or acute liver failure. Except the first patient, all patients had hospital visits within 7–21 days before measles onset and 20 patients were likely to be exposed to each other. Conclusions: The outcome of measles outbreak in previously vaccinated oncology and post-HSCT pediatric patients during chemotherapy and immunosuppressant medication was severe. Complete loss of protective immunity induced by measles vaccine during chemotherapy was the potential reason. Improved infection control practice was critical for the prevention of measles in malignancy patients and transplant recipients. PMID:28524832

    Ireland is classified as an area of high measles incidence. A World Health Organisation-European Region strategic plan exists for measles elimination by 2015. To retrospectively investigate measles outbreaks using all patient samples (sera and oral fluid) received for measles laboratory diagnosis and characterise the genetic diversity of circulating measles genotypes in Ireland. 704 cases of acute measles infection as determined by the presence of measles specific IgM in sera and oral fluids were confirmed at the National Virus Reference Laboratory. Measles positive samples (n=116) were examined by genotyping, sequence analysis and phylogenetic characterisation. Three measles outbreaks occurred over the study period: 2004, 2009/2010 and 2011. Measles IgM positivity ranged from 22-29% in outbreak years to 5-10% in the intervening years. Age profile analysis revealed that whereas individuals >10 years accounted for only 8% of cases in the 2004 outbreak, this increased to 33% and 29% in the 2009/2010 and 2011 outbreaks, respectively. The transmission and also importation events. Clade D viruses were exclusively found circulating in Ireland, with autochthonous transmission of diverse genotype D4 strains associated with large outbreaks across Europe. More recently, genotype D8 was identified and these were associated with importation events. This study provides a comprehensive genetic analysis of circulating measles genotypes in Ireland and discriminated between indigenous and imported viral strains. Notably, an increase in laboratory-confirmed measles cases in the greater than 10 years of age group was seen over the study period. This information is valuable to inform vaccination strategies with a focus on those populations who remain susceptible to measles infection. Copyright © 2014 Elsevier B.V. All rights reserved.

  19. Thermal Actuation Based 3-DoF Non-Resonant Microgyroscope Using MetalMUMPs

    Full Text Available High force, large displacement and low voltage consumption are a primary concern for microgyroscopes. The chevron-shaped thermal actuators are unique in terms of high force generation combined with the large displacements at a low operating voltage in comparison with traditional electrostatic actuators. A Nickel based 3-DoF micromachined gyroscope comprising 2-DoF drive mode and 1-DoF sense mode oscillator utilizing the chevron-shaped thermal actuators is presented here. Analytical derivations and finite element simulations are carried out to predict the performance of the proposed device using the thermo-physical properties of electroplated nickel. The device sensitivity is improved by utilizing the dynamical amplification of the oscillation in 2-DoF drive mode using an active-passive mass configuration. A comprehensive theoretical description, dynamics and mechanical design considerations of the proposed gyroscopes model are discussed in detail. Parametric optimization of gyroscope, its prototype modeling and fabrication using MetalMUMPs has also been investigated. Dynamic transient simulation results predicted that the sense mass of the proposed device achieved a drive displacement of 4.1µm when a sinusoidal voltage of 0.5V is applied at 1.77 kHz exhibiting a mechanical sensitivity of 1.7μm /o/s in vacuum. The wide bandwidth frequency response of the 2-DoF drive mode oscillator consists of two resonant peaks and a flat region of 2.11 kHz between the peaks defining the operational frequency region. The sense mode resonant frequency can lie anywhere within this region and therefore the amplitude of the response is insensitive to structural parameter variations, enhancing device robustness against such variations. The proposed device has a size of 2.2 x 2.6 mm2, almost one third in comparison with existing M-DoF vibratory gyroscope with an estimated power consumption of 0.26 Watts. These predicted results illustrate that the chevron

    Despite the availability of live attenuated measles virus (MV) vaccines, a large number of measles-associated deaths occur among infants in developing countries. The development of a measles subunit vaccine may circumvent the limitations associated with the current live attenuated vaccines and eventually contribute to global measles eradication. Therefore, the goal of this study was to test the feasibility of producing the recombinant globular head domain of the MV hemagglutinin (H) protein by stably transfected human cells and to examine the ability of this recombinant protein to elicit MV-specific immune responses. The recombinant protein was purified from the culture supernatant of stably transfected HEK293T cells secreting a tagged version of the protein. Two subcutaneous immunizations with the purified recombinant protein alone resulted in the production of MV-specific serum IgG and neutralizing antibodies in mice. Formulation of the protein with adjuvants (polyphosphazene or alum) further enhanced the humoral immune response and in addition resulted in the induction of cell-mediated immunity as measured by the production of MV H-specific interferon gamma (IFN-γ) and interleukin 5 (IL-5) by in vitro re-stimulated splenocytes. Furthermore, the inclusion of polyphosphazene into the vaccine formulation induced a mixed Th1/Th2-type immune response. In addition, the purified recombinant protein retained its immunogenicity even after storage at 37°C for 2 weeks. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2011-07-01

    Responding to regional advancements in combating measles, the World Health Organization in May 2008 called for an assessment of the feasibility of measles eradication, including whether sufficient vaccine supply exists. Interviews with international health officials and vaccine-makers provided data for a detailed model of worldwide demand and supply for measles-containing vaccine (MCV). The study projected global MCV demand through 2025 with and without a global eradication goal. The study found that 5.2 billion MCV doses must be administered during 2010-2025 to maintain current measles programs, and 5.9 billion doses would likely be needed with a 2020 eradication goal; in the most intensive scenario, demand could increase to 7.5 billion doses. These volumes are within existing and planned MCV-manufacturing capacity, although there are risks. In some markets, capacity is concentrated: Supply-chain disruptions could reduce supply or increase prices. Mitigation strategies could include stockpiling, long-term contracts, and further coordination with manufacturers. © The Author 2011.

    2017-10-13

    After 20years with no reported measles cases, on May 15, 2014 the Centers for Disease Control and Prevention (CDC) was notified of two cases testing positive for measles-specific immunoglobulin M (IgM) antibodies in the Federated States of Micronesia (FSM). Under the Compact of Free Association, FSM receives immunization funding and technical support from the United States (US) domestic vaccination program managed by the Centers for Disease Control and Prevention (CDC). In a collaborative effort, public health officials and volunteers from FSM and the US government worked to respond and contain the measles outbreak through an emergency mass vaccination campaign, contact tracing, and other outbreak investigation activities. Contributions were also made by United Nations Children's Emergency Fund (UNICEF) and World Health Organization (WHO). Total costs incurred as a result of the outbreak were nearly $4,000,000; approximately $10,000 per case. Direct medical costs (≈$141,000) were incurred in the treatment of those individuals infected, as well as lost productivity of the infected and informal caregivers (≈$250,000) and costs to contain the outbreak (≈$3.5 million). We assessed the economic burden of the 2014 measles outbreak to FSM, as well as the economic responsibilities of the US. Although the US paid the majority of total costs of the outbreak (≈67%), examining each country's costs relative to their respective economy illustrates a far greater burden to FSM. We demonstrate that while FSM was heavily assisted by the US in responding to the 2014 Measles Outbreak, the outbreak significantly impacted their economy. FSM's economic burden from the outbreak is approximately equivalent to their entire 2016 Fiscal Year budget dedicated to education. Published by Elsevier Ltd.

    Decreasing trends in measles mortality have been reported in recent years. However, such estimates of measles mortality have depended heavily on assumed regional measles case fatality risks (CFRs) and made little use of mortality data from low- and middle-income countries in general and India, the country with the highest measles burden globally, in particular. We constructed a dynamic model of measles transmission in India with parameters that were empirically inferred using spectral analysis from a time series of measles mortality extracted from the Million Death Study, an ongoing longitudinal study recording deaths across 2.4 million Indian households and attributing causes of death using verbal autopsy. The model was then used to estimate the measles CFR, the number of measles deaths, and the impact of vaccination in 2000-2015 among under-five children in India and in the states of Bihar and Uttar Pradesh (UP), two states with large populations and the highest numbers of measles deaths in India. We obtained the following estimated CFRs among under-five children for the year 2005: 0.63% (95% confidence interval (CI): 0.40-1.00%) for India as a whole, 0.62% (0.38-1.00%) for Bihar, and 1.19% (0.80-1.75%) for UP. During 2000-2015, we estimated that 607,000 (95% CI: 383,000-958,000) under-five deaths attributed to measles occurred in India as a whole. If no routine vaccination or supplemental immunization activities had occurred from 2000 to 2015, an additional 1.6 (1.0-2.6) million deaths for under-five children would have occurred across India. We developed a data- and model-driven estimation of the historical measles dynamics, CFR, and vaccination impact in India, extracting the periodicity of epidemics using spectral and coherence analysis, which allowed us to infer key parameters driving measles transmission dynamics and mortality.

    The United Kingdom achieved interrupted endemic measles transmission for 36 months in 2016. Despite this, ongoing challenges from sporadic measles cases typically imported from abroad remain. We summarise a B3 measles genotype outbreak in south-east Wales occurring between May and September 2017, linked with other European outbreaks, and lessons learnt. Seventeen confirmed cases and one probable case occurred principally in education and healthcare-settings. Six confirmed cases attended healthcare settings when infectious, without being isolated.

  6. What Obstetric Health Care Providers Need to Know About Measles and Pregnancy

    Rasmussen, Sonja A.; Jamieson, Denise J.

    2015-01-01

    From January 1 to April 3, 2015, 159 people from 18 states and the District of Columbia were reported as having measles. Most cases are part of an outbreak linked to a California amusement park. Because measles was eliminated in the United States in 2000, most U.S. clinicians are unfamiliar with the condition. We reviewed information on the current outbreak, measles manifestations, diagnostic methods, treatment, and infection-control recommendations. To identify information on measles and pregnancy, we reviewed reports with 20 or more measles cases during pregnancy that included data on effects on pregnant women or pregnancy outcomes. These reports were identified through MEDLINE from inception through February 2015 using the following strategy: (((pregnan*) AND measles) AND English[Language]) NOT review[Publication Type]. Reference lists also were reviewed to identify additional articles. Pregnant women infected with measles are more likely to be hospitalized, develop pneumonia, and die than nonpregnant women. Adverse pregnancy outcomes, including pregnancy loss, preterm birth, and low birth weight, are associated with maternal measles; however, the risk of congenital defects does not appear to be increased. No antiviral therapy is available; treatment is supportive. Early identification of possible cases is needed so that appropriate infection control can be instituted promptly. The recent measles outbreak highlights the role that obstetric health care providers play in vaccine-preventable illnesses; obstetrician–gynecologists should ensure that patients are up to date on all vaccines, including measles-containing vaccines, and should recommend and ideally offer a measles-containing vaccine to women without evidence of measles immunity before or after pregnancy.

  7. The Measles Virus Receptor SLAMF1 Can Mediate Particle Endocytosis.

    Gonçalves-Carneiro, Daniel; McKeating, Jane A; Bailey, Dalan

    2017-04-01

    The signaling lymphocyte activation molecule F1 (SLAMF1) is both a microbial sensor and entry receptor for measles virus (MeV). Herein, we describe a new role for SLAMF1 to mediate MeV endocytosis that is in contrast with the alternative, and generally accepted, model that MeV genome enters cells only after fusion at the cell surface. We demonstrated that MeV engagement of SLAMF1 induces dramatic but transient morphological changes, most prominently in the formation of membrane blebs, which were shown to colocalize with incoming viral particles, and rearrangement of the actin cytoskeleton in infected cells. MeV infection was dependent on these dynamic cytoskeletal changes as well as fluid uptake through a macropinocytosis-like pathway as chemical inhibition of these processes inhibited entry. Moreover, we identified a role for the RhoA-ROCK-myosin II signaling axis in this MeV internalization process, highlighting a novel role for this recently characterized pathway in virus entry. Our study shows that MeV can hijack a microbial sensor normally involved in bacterial phagocytosis to drive endocytosis using a complex pathway that shares features with canonical viral macropinocytosis, phagocytosis, and mechanotransduction. This uptake pathway is specific to SLAMF1-positive cells and occurs within 60 min of viral attachment. Measles virus remains a significant cause of mortality in human populations, and this research sheds new light on the very first steps of infection of this important pathogen. IMPORTANCE Measles is a significant disease in humans and is estimated to have killed over 200 million people since records began. According to current World Health Organization statistics, it still kills over 100,000 people a year, mostly children in the developing world. The causative agent, measles virus, is a small enveloped RNA virus that infects a broad range of cells during infection. In particular, immune cells are infected via interactions between glycoproteins found

    Despite the increase of immunization coverage (administrative) of measles in the country, there are widespread outbreaks of measles. In this respect, we investigated one of the outbreaks that occurred in hard to reach kebeles of Guji Zone, Oromia region, to identify the contributing factors that lead to the protracted outbreak of measles. We used a cross-sectional study design to investigate a measles outbreak in Guji zone, Oromia region. Data entry and analysis was performed using EPI-Info version 7.1.0.6 and MS-Microsoft Excel. In three months' time a total of 1059 suspected cases and two deaths were reported from 9 woredas affected by a measles outbreak in Guji zone. The cumulative attack rate of 81/100,000 population and case fatality ratio of 0.2% was recorded. Of these, 821 (77.5%) cases were measles vaccine. Although, all age groups were affected under five years old were more affected 495 (48%) than any other age groups. In response to the outbreak, an outbreak response immunization was organized at the 11th week of the epidemic, when the epidemic curve started to decline. 6 months to14 years old were targeted for outbreak response immunization and the overall coverage was 97 % (range: 90-103%). Case management with vitamin A supplementation, active case search, and health education was some of the activities carried out to curb the outbreak. We conclude that low routine immunization coverage in conjunction with low access to routine immunization in hard to reach areas, low community awareness in utilization of immunization service, inadequate cold chain management and delivery of a potent vaccine in hard to reach woredas/kebeles were likely contributed to the outbreak that's triggered a broad spread epidemic affecting mostly children without any vaccination. We also figured that the case-based surveillance lacks sensitivity and timely confirmation of the outbreak, which as a result outbreak response immunization were delayed. We recommend establishing

    Full Text Available A goal for measles elimination globally by 2010–2020 was recognized as one of the priorities in the WHO program “Health for All in the 21st Century” (1998. However measles outbreaks occurred in 2010–2016 in countries with high level of measles vaccine coverage including USA and some European countries.Large measles outbreaks were also registered on the African continent and particular in the Republic of Guinea as a result of the decline of measles vaccine coverage due to the Ebola virus epidemic in the Republic of Guinea in 2014–2015. WHO recommends carrying out the routine measles vaccination as well as the supplemental immunization activities after the stop of the Ebola virus transmission. Effectiveness of the activities is definitely connected with the detection of the epidemically significant for the supplemental immunization age groups. The aim of the study was to evaluate the measles immunity level in different age groups of population in the Republic of Guinea. Materials and methods. Twenty five blood serum samples of healthy adult Guineans aged 28–66 and 121 blood serum samples of adolescences and adults admitted to hospital in the town of Kindia (Republic of Guinea for indoor treatment were tested by ELISA. The specific measles virus antibodies were detected using the following commercial ELISA test-systems produced by Euroimmun Medizinische Labordiagnostika AG Company (Germany: IgM-antibodies — by “Anti-Measles Virus ELISA (IgM”, IgG-antibodi es — by “Anti-Measles Virus ELISA (IgG”, IgG-avidity measles virus antibodies — by “Avidity: Anti-Measles Virus ELISA (IgG”. A part of sera was studied by “Vector-Best IgM-measles” and “Vector-Best IgG-measles” ELISA test-systems (Russia. Results and discussion. The comparative quantitative study of the measles immunity level (i.e. IgG-antibodies titers of the healthy adult Guineans in 2015 and 2016 revealed the lack of IgGantibodies in serum

    A search for the lepton-flavour violating decays $B^0_s \\rightarrow e^{\\pm}\\mu^{\\mp}$ and $B^0 \\rightarrow e^{\\pm} \\mu^{\\mp}$ is performed with a data sample, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of $pp$ collisions at $\\sqrt{s} = 7$, TeV, collected by the LHCb experiment. The observed number of $B^0_s \\to e^{\\pm} \\mu^{\\mp}$ and $B^0 \\to e^{\\pm} \\mu^{\\mp}$ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be $BR(B^0_s \\to e^{\\pm} \\mu^{\\mp} 107$ TeV/c$^2$ and $M_{\\rm LQ} (B^0 \\to e^{\\pm} \\mu^{\\mp}) > 126$ TeV/c$^2$ at 95% C.L., and are a factor of two higher than the previous bounds.

  11. Measles and respiratory failure: Case report and review of the last European outbreaks

    2015-08-01

    Full Text Available Measles is an preventable acute viral illness, with the potential for severe and fatal complications. According to the European Centre for Disease Prevention and Control in the last surveillance report, a total of 10 271 cases of measles were reported from January to December 2013. And 127 of those were reported in Spain with a 2.7/1 million habitants rate. In 2010, the World Health Organization European Region made a new commitment to eradicate measles by 2015 in the zone, however, measles cases and outbreaks are still occurring in many countries. We present the last 2 cases with severe measles-associated respiratory failure and a review of the literature of the last European outbreaks. Two young adults were admitted in the intensive care unit due to respiratory failure with a confirmed measles infection. Both treated with high flow nasal cannula during 3 to 5 days; one had a pneumococcal pneumonia coinfection. An incomplete vaccination schedule was documented in one of them while the other did not remember his. Within 10 days of admission, both were discharged from intensive care unit and the hospital with no complications. Measles can present with a variety of symptoms in adults and is responsible for a high morbidity especially during outbreaks. Pneumonia is a severe complication of measles infection, commonly reported. Surveillance and vaccination programs should be strengthened in order to achieve measles elimination.

    In accordance with the goal of the World Health Organization Regional Office for Europe, the Italian National Measles and Rubella Elimination Plan aimed to interrupt indigenous measles transmission in Italy by the end of 2015. However, from 2013 to 2015, Italy experienced high measles burden with 4902 measles cases (49.3% laboratory-confirmed) reported to the enhanced measles surveillance system (cumulative incidence in the triennium reference period: 2.4/100,000 population). The measles elimination goal was not reached. Laboratory surveillance of measles circulating genotypes is performed by the Measles and Rubella National Reference Laboratory (NRL) at the Italian National Institute of Health (Istituto Superiore di Sanità - ISS), in Rome. Samples received from 1 January 2013-31 December 2015 were analysed. Those positive for measles genome by molecular tests were sequenced and phylogenetically analysed. Phylogenetic analysis performed by NRL identified that genotypes D4 and D8 were endemic and co-circulated in 2011-2013: study results show that genotype D4 disappeared during 2013. Sporadic cases were associated to genotype B3 during 2011-2013, which became endemic in Italy during 2014 and co-circulated with D8 until 2015. Sporadic cases were found belonging to genotypes D9 and H1 all over the period in exam. Similar trend has been observed in European WHO Region. Copyright © 2017 Elsevier B.V. All rights reserved.

  13. Drivers of measles mortality: the historic fatality burden of famine in Bangladesh.

    Mahmud, A S; Alam, N; Metcalf, C J E

    2017-12-01

    Measles is a major cause of childhood morbidity and mortality in many parts of the world. Estimates of the case-fatality rate (CFR) of measles have varied widely from place to place, as well as in the same location over time. Amongst populations that have experienced famine or armed conflict, measles CFR can be especially high, although past work has mostly focused on refugee populations. Here, we estimate measles CFR between 1970 and 1991 in a rural region of Bangladesh, which experienced civil war and famine in the 1970s. We use historical measles mortality data and a mechanistic model of measles transmission to estimate the CFR of measles. We first demonstrate the ability of this model to recover the CFR in the absence of incidence data, using simulated mortality data. Our method produces CFR estimates that correspond closely to independent estimates from surveillance data and we can capture both the magnitude and the change in CFR suggested by these previous estimates. We use this method to quantify the sharp increase in CFR that resulted in a large number of deaths during a measles outbreak in the region in 1976. Most of the children who died during this outbreak were born during a famine in 1974, or in the 2 years preceding the famine. Our results suggest that the period of turmoil during and after the 1971 war and the sustained effects of the famine, is likely to have contributed to the high fatality burden of the 1976 measles outbreak in Matlab.

  14. Case report: Ribavirin and vitamin A in a severe case of measles.

    Despite a vaccine being widely available, measles continues to occur frequently, with sometimes lethal consequences. The mortality rate reaches 35% and measles represents 44% of the 1.4 million deaths which are due to preventable diseases. Severe forms of measles are reported, mainly in young, unvaccinated adults, and in specific populations. The risk factors for severe measles include no or incomplete vaccination and vitamin A deficiency. Apart from secondary measles-related infections, severe measles is mainly represented by neurological, respiratory, and digestive symptoms. Strengthening the hypothesis that there is a link between vitamin A deficiency and severe measles in this paper we report the case of a 25-year-old unvaccinated man hospitalized for severe and complicated measles. The evolution was good after administration of intramuscular vitamin A as well as intravenous ribavirin. Measles remains a fatal and serious disease. The early use of ribavirin and vitamin A shows significant improvements regarding morbimortality and should be systematic in severe cases. Copyright © 2017 The Authors.

  15. The impact of declining vaccination coverage on measles control: a case study of Abia state Nigeria.

    Umeh, Chukwuemeka Anthony; Ahaneku, Hycienth Peterson

    2013-01-01

    Efforts at immunizing children against measles was intensified in Nigeria with nation-wide measles vaccination campaigns in 2005-2006, 2008 and 2011 targeting children between 9 and 59 months. However, there were measles outbreaks in 2010 and 2011 in Abia state Nigeria. This study seeks to find out if there is any association between measles immunization coverage and measles outbreak. This is a descriptive analysis of the 2007 to 2011 Abia state measles case-based surveillance data supplied to Abia state World Health Organization office and Abia State Ministry of Health by the disease surveillance and notification officers. As the proportion of cases with febrile rash who were immunized decreased from 81% in 2007 to 42% in 2011, the laboratory confirmed cases of measles increased from two in 2007 to 53 in 2011.Of the laboratory confirmed cases of measles, five (7%) occurred in children Abia state bearing in mind that measles immunization coverage in urban and rural areas was not markedly different.

    Until the mid-20th century, mortality rates were often very high during measles epidemics, particularly among previously isolated populations (e.g., islanders), refugees/internees who were forcibly crowded into camps, and military recruits. Searching for insights regarding measles mortality rates, we reviewed historical records of measles epidemics on the Polynesian island of Rotuma (in 1911), in Boer War concentration camps (in 1900-1902), and in US Army mobilization camps during the First World War (in 1917-1918). Records classified measles deaths by date and clinical causes; by demographic characteristics, family relationships (for Rotuma islanders and Boer camp internees), and prior residences; and by camp (for Boer internees and US Army recruits). During the Rotuman and Boer War epidemics, measles-related mortality rates were high (up to 40%); however, mortality rates differed more than 10-fold across camps/districts, even though conditions were similar. During measles epidemics, most deaths among camp internees/military recruits were due to secondary bacterial pneumonias; in contrast, most deaths among Rotuman islanders were due to gastrointestinal complications. The clinical expressions, courses, and outcomes of measles during first-contact epidemics differ from those during camp epidemics. The degree of isolation from respiratory pathogens other than measles may significantly determine measles-related mortality risk.

  17. Measles hectic in Pakistan; Upsurge versus the lurking vaccination.

    2015-02-01

    Measles has claimed more lives than anticipated, as the outbreaks hit Pakistan severely in 2013 as compared to 2012. Claiming 350 lives through the year 2013, Measles became a headache for the health agencies, authorities and common people. The sudden appearance of the virus in different parts of the country both rural and urban at the same time can be linked to more than one cause. The notable being corruption in health system, poor health infrastructure, destabilized routine immunization, shortage in number of vaccinators, negligence among parents, and floods. As a consequence of these causative factors, the unclear picture of immunization coverage can be presumed as the ultimate etiology of outbreaks in such numbers. Therefore, there is an urgent need to draw out the actual data of immunisation coverage and focus on elimination of hurdles in the road to success in fully coverage with vaccines.

  18. Mitigating measles outbreaks in West Africa post-Ebola.

    Truelove, Shaun A; Moss, William J; Lessler, Justin

    2015-01-01

    The Ebola outbreak in 2014-2015 devastated the populations, economies and healthcare systems of Guinea, Liberia and Sierra Leone. With this devastation comes the impending threat of outbreaks of other infectious diseases like measles. Strategies for mitigating these risks must include both prevention, through vaccination, and case detection and management, focused on surveillance, diagnosis and appropriate clinical care and case management. With the high transmissibility of measles virus, small-scale reactive vaccinations will be essential to extinguish focal outbreaks, while national vaccination campaigns are needed to guarantee vaccination coverage targets are reached in the long term. Rapid and multifaceted strategies should carefully navigate challenges present in the wake of Ebola, while also taking advantage of current Ebola-related activities and international attention. Above all, resources and focus currently aimed at these countries must be utilized to build up the deficit in infrastructure and healthcare systems that contributed to the extent of the Ebola outbreak.

  19. Epidemiology of infectious disease: the example of measles.

    1977-01-01

    The situation of unacculturated Brazilian Amazon tribes is described. The isolation of these populations has been sufficiently tight that they have been free of most epidemic diseases of the cosmopolitan world, although diseases associated with persistent infection have a high prevalence. The history of measles epidemics in Amerind populations is reviewed and it is concluded that most deaths can be prevented by basic nursing care but that there is a residual excess mortality characteristic of these populations. Three Brazilian virgin-soil populations and one experienced tribe in Chile, the Mapuche, were vaccinated against measles. Elevated febrile responses were observed in the three virgin-soil populations relative to the fevers seen in the Mapuche and in cosmopolitan populations. Nutritional status, immunological experience, humoral immune response and genetic characters have been examined for an explanation of this phenomenon. The most pronounced correspondence detected so far is a high degree of homozygosity in HLA loci of the virgin populations.

  2. A Mumps Outbreak in Vojvodina, Serbia, in 2012 Underlines the Need for Additional Vaccination Opportunities for Young Adults.

    Jasminka Nedeljković

    Full Text Available In 2012, mumps was introduced from Bosnia and Herzegovina to Vojvodina, causing an outbreak with 335 reported cases. The present manuscript analyses the epidemiological and laboratory characteristics of this outbreak, identifies its main causes and suggests potential future preventive measures. Sera of 133 patients were tested for mumps-specific antibodies by ELISA and 15 nose/throat swabs were investigated for mumps virus RNA by RT-PCR. IgG antibodies were found in 127 patients (95.5%. Mumps infection was laboratory-confirmed in 53 patients, including 44 IgM and 9 PCR positive cases. All other 282 cases were classified as epidemiologically-confirmed. More than half of the patients (n = 181, 54% were 20-29 years old, followed by the 15-19 age bracket (n = 95, 28.4%. Twice as many males as females were affected (67% versus 33%. Disease complications were reported in 13 cases (3.9%, including 9 patients with orchitis and 4 with pancreatitis. According to medical records or anamnestic data, 190 patients (56.7% were immunized with two doses and 35 (10.4% with one dose of mumps-containing vaccine. The Serbian sequences corresponded to a minor genotype G variant detected during the 2011/2012 mumps outbreak in Bosnia and Herzegovina. Vaccine failures, the initial one-dose immunization policy and a vaccine shortage between 1999 and 2002 contributed to the outbreak. Additional vaccination opportunities should be offered to young adults during transition periods in their life trajectories.

    2017-11-01

    Social media posts regarding measles vaccination were classified as pro-vaccination, expressing vaccine hesitancy, uncertain, or irrelevant. Spearman correlations with Centers for Disease Control and Prevention-reported measles cases and differenced smoothed cumulative case counts over this period were reported (using time series bootstrap confidence intervals). A total of 58,078 Facebook posts and 82,993 tweets were identified from 4 January 2009 to 27 August 2016. Pro-vaccination posts were correlated with the US weekly reported cases (Facebook: Spearman correlation 0.22 (95% confidence interval: 0.09 to 0.34), Twitter: 0.21 (95% confidence interval: 0.06 to 0.34)). Vaccine-hesitant posts, however, were uncorrelated with measles cases in the United States (Facebook: 0.01 (95% confidence interval: -0.13 to 0.14), Twitter: 0.0011 (95% confidence interval: -0.12 to 0.12)). These findings may result from more consistent social media engagement by individuals expressing vaccine hesitancy, contrasted with media- or event-driven episodic interest on the part of individuals favoring current policy.

  6. Positive predictive value and effectiveness of measles case-based surveillance in Uganda, 2012-2015.

    Fred Nsubuga

    Full Text Available Disease surveillance is a critical component in the control and elimination of vaccine preventable diseases. The Uganda National Expanded Program on Immunization strives to have a sensitive surveillance system within the Integrated Disease Surveillance and Response (IDSR framework. We analyzed measles surveillance data to determine the effectiveness of the measles case-based surveillance system and estimate its positive predictive value in order to inform policy and practice.An IDSR alert was defined as ≥1 suspected measles case reported by a district in a week, through the electronic Health Management Information System. We defined an alert in the measles case-based surveillance system (CBS as ≥1 suspected measles case with a blood sample collected for confirmation during the corresponding week in a particular district. Effectiveness of CBS was defined as having ≥80% of IDSR alerts with a blood sample collected for laboratory confirmation. Positive predictive value was defined as the proportion of measles case-patients who also had a positive measles serological result (IgM +. We reviewed case-based surveillance data with laboratory confirmation and measles surveillance data from the electronic Health Management Information System from 2012-2015.A total of 6,974 suspected measles case-persons were investigated by the measles case-based surveillance between 2012 and 2015. Of these, 943 (14% were measles specific IgM positive. The median age of measles case-persons between 2013 and 2015 was 4.0 years. Between 2013 and 2015, 72% of the IDSR alerts reported in the electronic Health Management Information System, had blood samples collected for laboratory confirmation. This was however less than the WHO recommended standard of ≥80%. The PPV of CBS between 2013 and 2015 was 8.6%.In conclusion, the effectiveness of measles case-based surveillance was sub-optimal, while the PPV showed that true measles cases have significantly reduced in Uganda

    2015-01-01

    Introduction Despite accelerated measles control efforts, a massive measles resurgence occurred in the Democratic Republic of the Congo (DRC) starting in mid-2010, prompting an investigation into likely causes. Methods We conducted a descriptive epidemiological analysis using measles immunization and surveillance data to understand the causes of the measles resurgence and to develop recommendations for elimination efforts in DRC. Results During 2004-2012, performance indicator targets for case-based surveillance and routine measles vaccination were not met. Estimated coverage with the routine first dose of measles-containing vaccine (MCV1) increased from 57% to 73%. Phased supplementary immunization activities (SIAs) were conducted starting in 2002, in some cases with sub-optimal coverage (≤95%). In 2010, SIAs in five of 11 provinces were not implemented as planned, resulting in a prolonged interval between SIAs, and a missed birth cohort in one province. During July 1, 2010-December 30, 2012, high measles attack rates (>100 cases per 100,000 population) occurred in provinces that had estimated MCV1 coverage lower than the national estimate and did not implement planned 2010 SIAs. The majority of confirmed case-patients were aged measles virus strains that were previously identified in the region. Conclusion The resurgence was likely caused by an accumulation of unvaccinated, measles-susceptible children due to low MCV1 coverage and suboptimal SIA implementation. To achieve the regional goal of measles elimination by 2020, efforts are needed in DRC to improve case-based surveillance and increase two-dose measles vaccination coverage through routine services and SIAs.

  8. Determinants of apparent rural-urban differentials in measles vaccination uptake in Indonesia.

    Fernandez, Renae C; Awofeso, Niyi; Rammohan, Anu

    2011-01-01

    Regional differences in vaccination uptake are common in both developed and developing countries, and are often linked to the availability of healthcare services and socioeconomic factors. In 2007, 0.9 million eligible Indonesian children missed measles vaccination, and 19 456 cases of measles were documented among Indonesian children. The authors investigated rural-urban differentials in measles vaccination coverage among young Indonesian children, and sought to identify key factors influencing the probability of a child receiving the first dose of measles vaccination in Indonesia. Data used in the analyses were sourced from the nationally representative Indonesia Demographic and Health Survey 2007. The influence of location of residence, household wealth, maternal and paternal education, total children ever born and use of skilled birth attendants on measles vaccination coverage was investigated using bivariate analysis and chi-square tests. The independent effects of these variables were established using binomial logistic regression analysis. Indonesia's 2007 first-dose measles national vaccination coverage was, at 72.8%, lower than the 2008 global first-dose measles vaccination average coverage of 82%. Bivariate analysis revealed that the first-dose measles vaccination coverage in rural areas of Indonesia was 68.5%, compared with 80.1% in urban regions (p rural residence in impairing vaccination coverage was marginal after controlling for the sex of the child, maternal age, maternal and paternal education, wealth, and access to skilled health workers. Apart from sustainable initiatives to increase measles vaccination coverage globally, it is important to close the rural-urban gap in Indonesia's measles vaccination uptake. Addressing critical determinants of inferior measles vaccination coverage in Indonesia's rural regions will facilitate major improvements in Indonesia's child health trends. This article suggests initiatives for addressing three of such

    Full Text Available Abstract Background Genetic analysis of measles viruses associated with recent cases and outbreaks has proven to bridge information gaps in routine outbreak investigations and has made a substantial contribution to measles control efforts by helping to identify the transmission pathways of the virus. Materials and methods The present study describes the genetic characterization of wild type measles viruses from Uttar Pradesh, India isolated between January 2008 and January 2011. In the study, 526 suspected measles cases from 15 outbreaks were investigated. Blood samples were collected from suspected measles outbreaks and tested for the presence of measles specific IgM; throat swab and urine samples were collected for virus isolation and RT-PCR. Genotyping of circulating measles viruses in Uttar Pradesh was performed by sequencing a 450-bp region encompassing the nucleoprotein hypervariable region and phylogenetic analysis. Results and conclusion Based on serological results, all the outbreaks were confirmed as measles. Thirty eight strains were obtained. Genetic analysis of circulating measles strains (n = 38 in Uttar Pradesh from 235 cases of laboratory-confirmed cases from 526 suspected measles cases between 2008 and 2011 showed that all viruses responsible for outbreaks were within clade D and all were genotype D8. Analysis of this region showed that it is highly divergent (up to 3.4% divergence in the nucleotide sequence and 4.1% divergence in the amino acid sequence between most distant strains. Considerable genetic heterogeneity was observed in the MV genotype D8 viruses in North India and underscores the need for continued surveillance and in particular increases in vaccination levels to decrease morbidity and mortality attributable to measles.

    Immunogenicity testing in animals is a necessary preclinical assay for demonstration of vaccine efficacy the results of which are often the basis for the decision whether to proceed or withdraw the further development of the novel vaccine candidate. However, in vivo assays are rarely, if at all, optimized and validated. Here we clearly demonstrate the importance of in vivo assay (mumps virus immunogenicity testing in guinea pigs) optimization for gaining reliable results and the suitability of Fractional factorial design of experiments (DoE) for such a purpose. By the use of DoE with resolution IV (2IV((4-1))) we clearly revealed that the parameters significantly increasing assay sensitivity were interval between animal immunizations followed by the body weight of experimental animals. The quantity (0 versus 2%) of the stabilizer (fetal bovine serum, FBS) in the sample was shown as non-influencing parameter in DoE setup. However, the separate experiment investigating only the FBS influence, and performed under other parameters optimally set, showed that FBS also influences the results of immunogenicity assay. Such finding indicated that (a) factors with strong influence on the measured outcome can hide the effects of parameters with modest/low influence and (b) the matrix of mumps virus samples to be compared for immunogenicity must be identical for reliable virus immunogenicity comparison. Finally the 3 mumps vaccine strains widely used for decades in the licensed vaccines were for the first time compared in an animal model, and results obtained were in line with their reported immunogenicity in human population supporting the predictive power of the optimized in vivo assay.

    In line with WHO objectives, the Lao Government is committed to eliminate measles by 2012. Yet from 1992 to 2007, the annual incidence of measles remained high while the vaccination coverage showed a wide diversity across provinces. A descriptive study was performed to determine factors affecting compliance with vaccination against measles, which included qualitative and quantitative components. The qualitative study used a convenience sample of 13 persons in charge of the vaccination program, consisting of officials from different levels of the health care structure and members of vaccination teams. The quantitative study performed on the target population consisted of a matched, case-control survey conducted on a stratified random sample of parents of children aged 9-23 months. Overall, 584 individuals (292 cases and 292 controls) were interviewed in the three provinces selected because of low vaccination coverage. On the provision of services side (supply), the main problems identified were a lack of vaccine supply and diluent, a difficulty in maintaining the cold chain, a lack of availability and competence among health workers, a lack of coordination and a limited capacity to assess needs and make coherent decisions. In the side of the consumer (demand), major obstacles identified were poor knowledge about measles immunization and difficulties in accessing vaccination centers because of distance and cost. In multivariate analysis, a low education level of the father was a factor of non-immunization while the factors of good compliance were high incomes, spacing of pregnancies, a feeling that children must be vaccinated, knowledge about immunization age, presenting oneself to the hospital rather than expecting the mobile vaccination teams and last, immunization of other family members or friends' children. The main factors affecting the compliance with vaccination against measles in Laos involve both the supply side and the demand side. Obtaining an effective

    During 2001-2008, the Victorian Infectious Diseases Reference Laboratory (VIDRL) prepared and provided a measles and rubella proficiency test panel for distribution to the World Health Organization (WHO) measles and rubella network laboratories as part of their annual laboratory accreditation assessment. Panel test results were forwarded to VIDRL, and results from 8 consecutive years were analyzed. We assessed the type of assays used and results achieved on the basis of the positive and negative interpretation of submitted results, by year and WHO region, for measles and rubella. Over time, there has been a noticeable increase in laboratory and WHO regional participation. For all panels, the proportion of laboratories in all WHO regions using the WHO-validated Dade Behring assay for measles and rubella-specific IgM antibodies ranged from 35% to 100% and 59% to 100%, respectively. For all regions and years, the proportion of laboratories obtaining a pass score ranged from 87% to 100% for measles and 93% to 100% for rubella. During 2001-2008, a large proportion of laboratories worldwide achieved and maintained a pass score for both measles and rubella. Measles and rubella proficiency testing is regarded as a major achievement for the WHO measles and rubella laboratory program. © The Author 2011.

    Full Text Available subacute sclerosing panencephalitis (SSPE is a late, rare and usually fatal complication of measles infection. Although a very high incidence of SSPE in Papua New Guinea (PNG was first recognized 20 years ago, estimated measles vaccine coverage has remained at ≤ 70% since and a large measles epidemic occurred in 2002. We report a series of 22 SSPE cases presenting between November 2007 and July 2009 in Madang Province, PNG, including localized clusters with the highest ever reported annual incidence.as part of a prospective observational study of severe childhood illness at Modilon Hospital, the provincial referral center, children presenting with evidence of meningo-encephalitis were assessed in detail including lumbar puncture in most cases. A diagnosis of SSPE was based on clinical features and presence of measles-specific IgG in cerebrospinal fluid and/or plasma. The estimated annual SSPE incidence in Madang province was 54/million population aged 100/million/year. The distribution of year of birth of the 22 children with SSPE closely matched the reported annual measles incidence in PNG, including a peak in 2002.SSPE follows measles infections in very young PNG children. Because PNG children have known low seroconversion rates to the first measles vaccine given at 6 months of age, efforts such as supplementary measles immunisation programs should continue in order to reduce the pool of non-immune people surrounding the youngest and most vulnerable members of PNG communities.

  8. Record High US Measles Cases: Patient Vaccination, Clinical Assessment and Management

    This podcast is an overview of the Clinician Outreach and Communication Activity (COCA) Call: Record High US Measles Cases: Patient Vaccination, Clinical Assessment and Management. In May 2014, the United States recorded the largest number of reported measles cases since 1994 and the number continues to rise. Most cases reported have been acquired in the U.S. and are associated with importations from countries where measles is still common. This highly contagious, acute viral illness spreads quickly in unvaccinated populations once reaching the U.S. The recent measles outbreaks highlight the importance of maintaining high vaccination coverage in the U.S. and ensuring age-appropriate vaccination for international travelers. During this COCA call, clinicians will learn the status of measles in the U.S. and CDC vaccination recommendations and guidelines for patient assessment and management.

    The measles virus (MV) is serologically monotypic. Life-long immunity is conferred by a single attack of measles or following vaccination with the MV vaccine. This is contrary to viruses such as influenza, which readily develop resistance to the immune system and recur. A better understanding of factors that restrain MV to one serotype may allow us to predict if MV will remain monotypic in the future and influence the design of novel MV vaccines and therapeutics. MV hemagglutinin (H) glycoprotein, binds to cellular receptors and subsequently triggers the fusion (F) glycoprotein to fuse the virus into the cell. H is also the major target for neutralizing antibodies. To explore if MV remains monotypic due to a lack of plasticity of the H glycoprotein, we used the technology of Immune Dampening to generate viruses with rationally designed N-linked glycosylation sites and mutations in different epitopes and screened for viruses that escaped monoclonal antibodies (mAbs). We then combined rationally designed mutations with naturally selected mutations to generate a virus resistant to a cocktail of neutralizing mAbs targeting four different epitopes simultaneously. Two epitopes were protected by engineered N-linked glycosylations and two epitopes acquired escape mutations via two consecutive rounds of artificial selection in the presence of mAbs. Three of these epitopes were targeted by mAbs known to interfere with receptor binding. Results demonstrate that, within the epitopes analyzed, H can tolerate mutations in different residues and additional N-linked glycosylations to escape mAbs. Understanding the degree of change that H can tolerate is important as we follow its evolution in a host whose immunity is vaccine induced by genotype A strains instead of multiple genetically distinct wild-type MVs.

    Full Text Available Abstract Background Despite increased funding of measles vaccination programs by national governments and international aid agencies, structural factors encumber attainment of childhood measles immunisation to levels which may guarantee herd immunity. One of such factors is parental education status. Research on the links between parental education and vaccination has typically focused on the influence of maternal education status. This study aims to demonstrate the independent influence of paternal education status on measles immunisation. Methods Comparable nationally representative survey data were obtained from six countries with the highest numbers of children missing the measles vaccine in 2008. Logistic regression analysis was applied to examine the influence of paternal education on uptake of the first dose of measles vaccination, independent of maternal education, whilst controlling for confounding factors such as respondent’s age, urban/rural residence, province/state of residence, religion, wealth and occupation. Results The results of the analysis show that even if a mother is illiterate, having a father with an education of Secondary (high school schooling and above is statistically significant and positively correlated with the likelihood of a child being vaccinated for measles, in the six countries analysed. Paternal education of secondary or higher level was significantly and independently correlated with measles immunisation uptake after controlling for all potential confounders. Conclusions The influence of paternal education status on measles immunisation uptake was investigated and found to be statistically significant in six nations with the biggest gaps in measles immunisation coverage in 2008. This study underscores the imperative of utilising both maternal and paternal education as screening variables to identify children at risk of missing measles vaccination prospectively.

    Measles virus infection remains a significant cause of childhood mortality and morbidity despite continued global efforts and the availability of a safe and effective vaccine. Molecular analysis of indigenous measles viruses could provide critical information on outbreak linkages and transmission pathways that can aid the implementation of appropriate control programs in Pakistan. Blood samples and throat swabs were collected from subjects suspected with measles in Islamabad, Pakistan from 2013 to 2015. Serum samples were tested for the presence of measles immunoglobulin M (IgM) antibodies using enzyme-linked immunosorbent assay (ELISA) while throat swabs were used for the isolation (Vero/SLAM cell line) and subsequent characterization and phylogenetic analysis of measles strains. Of 373 blood samples, 66% tested positive for measles IgM. Male subjects were more often infected (58%) than female (42%) with the highest frequency of positive cases (63%) in the 0-5-years age group. Among the positive cases, only 13% had received one or two doses of the measles vaccine, while 87% were unvaccinated. Of 80 throat swabs, 29 (36%) showed a measles virus-specific cytopathic effect (CPE) and were characterized as genotype B3 through partial sequencing of the nucleoprotein (N) gene. Phylogenetic analysis revealed the Pakistani B3 strains to be closely related to strains from neighboring countries (Iran and Afghanistan) as well as with B3 viruses from the USA, Germany, and the UK. The study results showed that despite the availability of an effective vaccine, the burden of measles infections is very high in Pakistan due to poor routine immunization coverage even in major cities, including the capital city of Islamabad. It is imperative that national health authorities take urgent strategic steps to improve routine immunization and implement adequate molecular identification methods to tackle future measles outbreaks.

    2017-10-13

    During a large measles outbreak in the Netherlands in 2013-2014, infants aged 6-14months living in municipalities with low (<90%) measles-mumps-rubella (MMR) coverage were individually invited for an early MMR using the national electronic immunization register, Præventis. We estimated uptake of early MMR prior to and during the 2013-2014 outbreak and assessed determinants for early MMR vaccination. We obtained vaccination records from Præventis, and defined early MMR as vaccination before 415days (13months) of age. A multi-level multivariable logistic regression model, restricted to infants with three diphtheria-pertussis-tetanus-polio (DPTP) vaccinations was used to examine the association between early MMR uptake and sex, parents' country of birth, socioeconomic status (SES; at postcode level) and voting proportions for the Reformed Political Party (SGP; at municipal level), used as a proxy for religious objections towards vaccination. In the 29 municipalities with low MMR coverage, uptake of early MMR was 0.5-2.2% prior to the outbreak. Between July 2013 and March 2014, 5,800 (57%) invited infants received an early MMR. Among infants with three DPTP, 70% received an early MMR. Only 1% of infants without prior DPTP received an early MMR. Lower early MMR uptake was associated with a higher SGP voter-ship (OR 0.89 per 5% increase, 95%CI 0.83-0.96), parents' with unknown country of birth (OR 0.66 95%CI 0.47-0.93) and compared with very high SES, high SES had significantly lower early MMR uptake (OR 0.66 95%CI 0.50-0.87). This is the first study describing use of Præventis during an outbreak and to assess determinants of early MMR uptake. More than half of invited infants obtained an early MMR. SES, parents' with unknown country of birth and religious objections towards vaccination were found to be associated with lower early MMR uptake. In future outbreaks, these determinants could be used to tailor intervention strategies. Copyright © 2017. Published by

    Background and purpose: We previously reported a therapeutic strategy comprising replication-defective NIS-expressing adenovirus combined with radioiodide, external beam radiotherapy (EBRT) and DNA repair inhibition. We have now evaluated NIS-expressing oncolytic measles virus (MV-NIS) combined with NIS-guided radioiodide, EBRT and specific checkpoint kinase 1 (Chk1) inhibition in head and neck and colorectal models. Materials and methods: Anti-proliferative/cytotoxic effects of individual agents and their combinations were measured by MTS, clonogenic and Western analysis. Viral gene expression was measured by radioisotope uptake and replication by one-step growth curves. Potential synergistic interactions were tested in vitro by Bliss independence analysis and in in vivo therapeutic studies. Results: EBRT and MV-NIS were synergistic in vitro. Furthermore, EBRT increased NIS expression in infected cells. SAR-020106 was synergistic with EBRT, but also with MV-NIS in HN5 cells. MV-NIS mediated 131 I-induced cytotoxicity in HN5 and HCT116 cells and, in the latter, this was enhanced by SAR-020106. In vivo studies confirmed that MV-NIS, EBRT and Chk1 inhibition were effective in HCT116 xenografts. The quadruplet regimen of MV-NIS, virally-directed 131 I, EBRT and SAR-020106 had significant anti-tumour activity in HCT116 xenografts. Conclusion: This study strongly supports translational and clinical research on MV-NIS combined with radiation therapy and radiosensitising agents

    Mumps outbreaks in populations with high 2-dose vaccination coverage and among young adults are increasingly reported. However, data on the duration of vaccine-induced protection conferred by mumps vaccines are scarce. As part of a supra-regional outbreak in Germany 2010/11, we conducted two retrospective cohort studies in a primary school and among adult ice hockey teams to determine mumps vaccine effectiveness (VE). Via questionnaires we collected information on demography, clinical manifestations, and reviewed vaccination cards. We estimated VE as 1-RR, RR being the rate ratio of disease among two-times or one-time mumps-vaccinated compared with unvaccinated persons. The response rate was 92.6% (100/108--children cohort) and 91.7% (44/48--adult cohort). Fourteen cases were identified in the children and 6 in the adult cohort. In the children cohort (mean age: 9 y), 2-dose VE was 91.9% (95% CI 81.0-96.5%). In the adult cohort (mean age: 26 y), no cases occurred among the 13 2-times vaccinated, while 1-dose VE was 50.0% (95% CI -9.4-87.1%). Average time since last vaccination showed no significant difference for cases and non-cases, but cases were younger at age of last mumps vaccination (children cohort: 2 vs. 3 y, P=0.04; adult cohort: 1 vs. 4 y, P=0.03). We did not observe signs of waning immunity in the children cohort. Due to the small sample size VE in the adult cohort should be interpreted with caution. Given the estimated VE, very high 2-dose vaccination coverage is required to prevent future outbreaks. Intervention efforts to increase coverage must especially target young adults who received<2 vaccinations during childhood.

    Mumps vaccine was introduced in the National Immunization Program in Portugal in 1987, rapidly reaching a national coverage > 92%, with important reduction in the annual incidence of the disease. We report a mumps outbreak in the Central Region of Portugal, occurred in the winter 2012-13. Cases of salivary-gland swelling and other symptoms compatible with mumps were investigated. Geodemographics, clinical, laboratory and vaccination data were analyzed. Over six months, 148 outbreak-related cases were reported: 87.8% occurred in three of the 16 affected counties and 78.4% had a known epidemiological link. Median age was 14.5 years (2-62) and 70.3% were 11-20 years old; 61.5% were male. The mean duration of disease was seven days (2-20). The disease was generally mild; 80.4% had fever and in 55.4% there was unilateral involvement of the parotid gland. Seven cases had orchitis, one oophoritis and one had nephritis. Two cases were hospitalized. School transmission predominated and class attack rates were < 30%. Most of the cases occurred in vaccinated individuals (92%) of whom 86.8% had received 2 doses; 17.7% had received one dose of the vaccine containing the Rubini strain. Mumps virus genotype G was identified in 4 cases. This mumps outbreak among a highly vaccinated population, occurring mostly in teenagers at school, could be due to the partial effectiveness of the vaccine against the disease (particularly in the group vaccinated with Rubini strain), waning immunity overtime and genotype mismatch. This outbreak report shows the importance of discussion about the need of more booster dose of the actual vaccine or new vaccine including more genotypes to improve immunogenicity.

    To evaluate vaccine effectiveness (VE) of mumps-containing vaccine (MuV) under different immunization strategies. We conducted Medline, Embase, China National Knowledge Internet (CNKI), and Wan Fang Database (WF) searches for Chinese and English language articles describing studies of mumps VE in a Chinese population. Evaluated articles were scored on quality using the Newcastle-Ottawa Scale. Meta-analysis was conducted using random effects models. Sensitivity analysis, subgroup analysis and meta-regression were conducted to explore heterogeneity. A total of 32 studies in 19 papers were included; 14 were case-control studies, and 18 were cohort studies. Half of the studies were of high quality; 41% were of moderate quality. The overall VE for mumps containing vaccine (either one dose or two doses) was 85% (95% CI 76-90%) for cohort studies and 88% (95% CI 82-92%) for case-control studies. Using random effects meta-regression we found significant differences in some study covariates; for instance, VE varied by population (VE=88% in day care versus 69% in pupil, p=0.008) and emergency versus routine immunization (VE=80% for routine immunization versus 95% for emergency immunization, p=0.041). However, these results must be interpreted with caution due to the low number of studies in subgroups, with the permutation test giving non-significant results that indicated that the results may be due to chance. MuV provides good protection from mumps infection. Further studies of mumps VE with larger sample sizes enabling subgroup analyses will be needed to confirm our findings.

    2001-01-01

    Aims—To compare prospectively the efficacy of the Vero, LLC-MK2, MDCK, Hep-2, and MRC-5 cell lines in the isolation of the mumps virus from clinical samples by means of the shell vial method. Methods—During an epidemic outbreak of parotiditis 48 clinical samples (saliva swabs and CSF) were studied. Two vials of the Vero, LLC-MK2, MDCK, MRC-5, and Hep-2 cell lines were inoculated with 0.2 ml of the samples by the shell vial assay. The vials were incubated at 36°C for two and five days. The vials were then fixed with acetone at -20°C for 10 minutes and stained by a monoclonal antibody against mumps virus by means of an indirect immunofluorescence assay. Results—The mumps virus was isolated from 36 samples. The Vero and LLC-MK2 cell lines showed a 100% isolation capacity, MDCK showed 77.7%, MRC-5 showed 44.4%, and Hep-2 showed 22.2%. The Vero and LLC-MK2 lines were significantly different to the other cell lines (p 5 infectious foci) were 94.4% for Vero, 97.2% for LLC-MK2, 5.5% for MDCK, 5.5% for Hep-2, and 0% for MRC-5. Conclusions—The Vero and LLC-MK2 cell lines are equally efficient at two and five days incubation for the isolation of the mumps virus from clinical samples, and the use of the shell vial method considerably shortens the time of aetiological diagnosis with higher specificity. Key Words: mumps virus • Vero cell line • LLC-MK2 cell line • MDCK cell line • Hep-2 cell line • MRC-5 cell line • isolation • shell vial PMID:11729211

  5. Prevalence of measles antibodies among health care workers in Catalonia (Spain) in the elimination era

    2013-01-01

    Background Interruption of measles transmission was achieved in Catalonia (Spain) in 2000. Six years later, a measles outbreak occurred between August 2006 and June 2007 with 381 cases, 11 of whom were health care workers (HCW). The objective was to estimate susceptibility to measles in HCW and related demographic and occupational characteristics. Methods A measles seroprevalence study was carried out in 639 HCW from six public tertiary hospitals and five primary healthcare areas. Antibodies were tested using the Vircell Measles ELISA IgG Kit. Data were analyzed according to age, sex, type of HCW, type of centre and vaccination history. The odds ratios (OR) and their 95% CI were calculated to determine the variables associated with antibody prevalence. OR were adjusted using logistic regression. Positive predictive values (PPV) and the 95% confidence intervals (CI) of having two documented doses of a measles containing vaccine (MCV) for the presence of measles antibodies and of reporting a history of measles infection were calculated. Results The prevalence of measles antibodies in HCW was 98% (95% CI 96.6-98.9), and was lower in HCW born in 1981 or later, after the introduction of systematic paediatric vaccination (94.4%; 95% CI 86.4-98.5) and higher in HCW born between 1965 and 1980 (99.0%; 95% CI 97.0-99.8). Significant differences were found for HCW born in 1965–1980 with respect to those born in 1981 and after (adjusted OR of 5.67; 95% CI: 1.24-25.91). A total of 187 HCW reported being vaccinated: the proportion of vaccinated HCW decreased with age. Of HCW who reported being vaccinated, vaccination was confirmed by the vaccination card in 49%. Vaccination with 2 doses was documented in only 50 HCW, of whom 48 had measles antibodies. 311 HCW reported a history of measles. The PPV of having received two documented doses of MCV was 96% (95% CI 86.3-99.5) and the PPV of reporting a history of measles was 98.7% (95% CI 96.7-99.6). Conclusions Screening to detect

    Molecular surveillance and advanced phylogenetic methods are important tools to track the pathways of Measles virus (MV) genotypes, provide evidence for the interruption of endemic transmission and verify the elimination of the disease. The aims of this study were to describe the genetic profile of MV genotype D8 (D8-MV) strains circulating in Northern Italy (Lombardy Region) during the 2013-2014 period and to analyze the transmission chains and estimate the introduction time points using a phylogenetic approach. Forty-four strains of D8-MV identified from 12 outbreaks and 28 cases reported as sporadic were analyzed. Molecular analysis was performed by sequencing the highly variable 450nt region of the N gene of MV genome (N-450), as recommended by the WHO. Phylogenetic analyses and tree time-scaled reconstruction were performed with BEAST software. We could trace back the transmission pathways that resulted in three chains of transmission, two introductions with limited spread (two familiar outbreaks), and two single introductions (true sporadic cases). The D8-Taunton transmission chain, which was involved in 7 outbreaks and 13 sporadic cases, was endemic during the studied period. Furthermore, two novel local variants emerged independently in March 2014 and caused two transmission chains linked to at least 3 outbreaks. Overall, viral diversity was high and strains belonging to 5 different variants were identified. The results of this study clearly demonstrate that multiple lineages of D8-MV co-circulated in Northern Italy. Measles can be considered a re-emerging disease in Italy and additional efforts are necessary to achieve measles elimination goal. Copyright © 2016 Elsevier B.V. All rights reserved.

  9. [Measles in Germany: An Epidemiological Analysis and First Measures for Containment].

    Matysiak-Klose, Dorothea; Wicker, Sabine

    2017-11-01

    Measles are one of the most contagious diseases of mankind. Measles incidence has declined worldwide since the introduction of vaccinations. Due to low numbers of measles cases in countries with high vaccination rates the population is not aware of possible complications of measles any more. Measles elimination is an important goal set by all regions of the World Health Organization. However, it remains a challenge for Germany and other European countries. Because of a high proportion of susceptibles in specific population and age groups outbreaks take place in Germany every year after importation of the virus. More than 50 % of measles cases are 20 years and older. However, the highest incidences have been seen in two-year-olds since several years. In addition to epidemiological findings such as case numbers and risk groups, genotyping permits e. g. an assessment of the endemic circulation of viruses. Suspicion of a measles case should result in immediate and consistent measures. © Georg Thieme Verlag KG Stuttgart · New York.

  10. High titer oncolytic measles virus production process by integration of dielectric spectroscopy as online monitoring system.

    2018-05-01

    Oncolytic viruses offer new hope to millions of patients with incurable cancer. One promising class of oncolytic viruses is Measles virus, but its broad administration to cancer patients is currently hampered by the inability to produce the large amounts of virus needed for treatment (10 10 -10 12 virus particles per dose). Measles virus is unstable, leading to very low virus titers during production. The time of infection and time of harvest are therefore critical parameters in a Measles virus production process, and their optimization requires an accurate online monitoring system. We integrated a probe based on dielectric spectroscopy (DS) into a stirred tank reactor to characterize the Measles virus production process in adherent growing Vero cells. We found that DS could be used to monitor cell adhesion on the microcarrier and that the optimal virus harvest time correlated with the global maximum permittivity signal. In 16 independent bioreactor runs, the maximum Measles virus titer was achieved approximately 40 hr after the permittivity maximum. Compared to an uncontrolled Measles virus production process, the integration of DS increased the maximum virus concentration by more than three orders of magnitude. This was sufficient to achieve an active Measles virus concentration of > 10 10 TCID 50 ml -1 . © 2017 Wiley Periodicals, Inc.

    2015-01-01

    Background To achieve a measles free world, effective communication must be part of all elimination plans. The choice of communication approaches must be evidence based, locally appropriate, interactive and community owned. In this article, we document the innovative approach of using house visits supported by a web-enabled mobile phone application to create a real-time platform for adaptive management of supplemental measles immunization days in Kenya. Methods One thousand nine hundred and fifty-two Red Cross volunteers were recruited, trained and deployed to conduct house-to-house canvassing in 11 urban districts of Kenya. Three days before the campaigns, volunteers conducted house visits with a uniform approach and package of messages. All house visits were documented using a web-enabled mobile phone application (episurveyor®) that in real-time relayed information collected to all campaign management levels. During the campaigns, volunteers reported daily immunizations to their co-ordinators. Post-campaign house visits were also conducted within 4 days, to verify immunization of eligible children, assess information sources and detect adverse events following immunization. Results Fifty-six per cent of the 164 643 households visited said that they had heard about the planned 2012 measles vaccination campaign 1–3 days before start dates. Twenty-five per cent of households were likely to miss the measles supplemental dose if they had not been reassured by the house visit. Pre- and post-campaign reasons for refusal showed that targeted communication reduced misconceptions, fear of injections and trust in herbal remedies. Daily reporting of immunizations using mobile phones informed changes in service delivery plans for better immunization coverage. House visits were more remembered (70%) as sources of information compared with traditional mass awareness channels like megaphones (41%) and radio (37%). Conclusions In high-density settlements, house-to-house visits

    Full Text Available OBJECTIVE: The clinical differential diagnosis of rash due to viral infections is often difficult, and misdiagnosis is not rare, especially after the introduction of measles and rubella vaccination. A study to determine the etiological diagnosis of exanthema was carried out in a group of children after measles vaccination. METHODS: Sera collected from children with rash who received measles vaccine were reported in 1999. They were analyzed for IgM antibodies against measles virus, rubella virus, human parvovirus B19 (HPV B19 using ELISA commercial techniques, and human herpes virus 6 (HHV 6 using immunofluorescence commercial technique. Viremia for each of those viruses was tested using a polimerase chain reaction (PCR. RESULTS: A total of 17 cases of children with exanthema after measles immunization were reported in 1999. The children, aged 9 to 12 months (median 10 months, had a blood sample taken for laboratory analysis. The time between vaccination and the first rash signs varied from 1 to 60 days. The serological results of those 17 children suspected of measles or rubella infection showed the following etiological diagnosis: 17.6% (3 in 17 HPV B19 infection; 76.5% (13 in 17 HHV 6 infection; 5.9% (1 in 17 rash due to measles vaccine. CONCLUSIONS: The study data indicate that infection due to HPV B19 or HHV 6 can be misdiagnosed as exanthema due to measles vaccination. Therefore, it is important to better characterize the etiology of rash in order to avoid attributing it incorrectly to measles vaccine.

  13. [Effectiveness, population-level effects, and heath economics of measles and rubella vaccination].

    Wichmann, O; Ultsch, B

    2013-09-01

    Vaccination against measles and rubella has been included in national immunization programs worldwide for several decades. In this article, we present the evidence related to the effectiveness of measles and rubella vaccination based on published systematic reviews, and we describe the epidemiological and health economic effects of vaccination at a population level. Several observational studies demonstrate the high effectiveness (> 90 %) of both measles and rubella vaccination. The global measles mortality reduction and the dramatic decrease in rubella and measles incidences after introduction of routine immunization contribute to the very high quality of evidence. The countries of the Americas have proved that it is feasible to eliminate measles and rubella by strengthening infant immunization through routine vaccination services and by conducting supplemental immunization activities in other childhood age groups so as to close immunity gaps. An economic evaluation of measles and rubella vaccination specifically for the healthcare system in Germany does not exist. However, we conducted a systematic review and identified 11 health-economic studies from other industrialized countries and one for a hypothetical industrialized country. Results indicate that vaccination against measles and rubella had either a cost-effective or even a cost-saving potential, which could be assumed with some limitations also for the German setting. In conclusion, there is compelling evidence that the available vaccines are very effective and that measles and rubella elimination is feasible if adequate vaccination strategies are implemented. In Germany, catch-up vaccination programs are urgently needed for children, adolescents, and young adults specifically in the western federal states.

  15. Structural and mechanistic studies of measles virus illuminate paramyxovirus entry.

    Richard K Plemper

    2011-06-01

    Full Text Available Measles virus (MeV, a member of the paramyxovirus family of enveloped RNA viruses and one of the most infectious viral pathogens identified, accounts for major pediatric morbidity and mortality worldwide although coordinated efforts to achieve global measles control are in place. Target cell entry is mediated by two viral envelope glycoproteins, the attachment (H and fusion (F proteins, which form a complex that achieves merger of the envelope with target cell membranes. Despite continually expanding knowledge of the entry strategies employed by enveloped viruses, our molecular insight into the organization of functional paramyxovirus fusion complexes and the mechanisms by which the receptor binding by the attachment protein triggers the required conformational rearrangements of the fusion protein remain incomplete. Recently reported crystal structures of the MeV attachment protein in complex with its cellular receptors CD46 or SLAM and newly developed functional assays have now illuminated some of the fundamental principles that govern cell entry by this archetype member of the paramyxovirus family. Here, we review these advances in our molecular understanding of MeV entry in the context of diverse entry strategies employed by other members of the paramyxovirus family.

Oncolytic measles virus (MV is one such virus that exhibits this characteristic and thus has rapidly emerged as a potentially useful anticancer modality. Derivatives of the Edmonston MV vaccine strain possess a remarkable safety record in humans. Promising results in preclinical animal models and evidence of biological activity in early phase trials contribute to the enthusiasm. Genetic modifications have enabled MV to evolve from a vaccine agent to a potential anticancer therapy. Specifically, alterations of the MV genome have led to improved tumor selectivity and delivery, therapeutic potency, and immune system modulation. In this article, we will review the advancements that have been made in the design and development of MV that have led to its use as a cancer therapy. In addition, we will discuss the evidence supporting its use, as well as the challenges associated with MV as a potential cancer therapeutic. Keywords: virotherapy, measles virus, oncolytic therapy

  17. Follow-up measles campaign in the Dominican Republic.

    1998-12-01

    The Dominican Republic conducted a national follow-up measles vaccination campaign 6 weeks after sustaining heavy damage from Hurricane Georges, on November 6-12, targeting 830,517 children aged 9 months to 5 years in 29 provinces and the capital city. This campaign was the first mass vaccination effort in the country, following the beginning of the decentralized delivery of health services. Priority was given to vaccinating against diphtheria, whooping cough, and tetanus, especially in refugee camps. More than 500,000 vaccines were given to different age groups, with almost 100,000 of those immunized under 5 years old. Children aged 9 months to 5 years were targeted for immunization regardless of their vaccination status. At the same time, children aged 2 months through 2 years were immunized against poliomyelitis. Vaccination activities were continued until the entire target population was reached and no important side effects have thus far been reported. The government of Mexico donated 300,000 doses of measles vaccine, while other vaccines for the campaign were acquired through the PAHO Revolving Fund for Vaccine Procurement. The decentralized implementation of this campaign allowed the population to actively participate and the resulting high vaccination coverage rates.

    Full Text Available Abstract Background Measles virus attenuation has been historically performed by adaptation to cell culture. The current dogma is that attenuated virus strains induce more type I IFN and are more resistant to IFN-induced protection than wild type (wt. Results The adaptation of a measles virus isolate (G954-PBL by 13 passages in Vero cells induced a strong attenuation of this strain in vivo. The adapted virus (G954-V13 differs from its parental strain by only 5 amino acids (4 in P/V/C and 1 in the M gene. While a vaccine strain, Edmonston Zagreb, could replicate equally well in various primate cells, both G954 strains exhibited restriction to the specific cell type used initially for their propagation. Surprisingly, we observed that both G954 strains induced type I IFN, the wt strain inducing even more than the attenuated ones, particularly in human plasmacytoid Dendritic Cells. Type I IFN-induced protection from the infection of both G954 strains depended on the cell type analyzed, being less efficient in the cells used to grow the viral strain. Conclusion Thus, mutations in M and P/V/C proteins can critically affect MV pathogenicity, cellular tropism and lead to virus attenuation without interfering with the α/β IFN system.

  19. Measles, social media and surveillance in Baltimore City.

    Warren, Katherine E; Wen, Leana S

    2017-09-01

    Baltimore City was faced with two potential measles outbreaks in 2015. Both cases occurred in the wake of national media attention paid to the Disneyland outbreaks of the same year. A comparative case study approach was used applying qualitative data to elicit best practices in infectious disease protocols in the age of social media. The research also used search engine data from Google Trends to track constituent engagement over time. Across the two case studies, the Baltimore City Health Department identified a number of best practices to inform the public via social media and minimize levels of misinformation and panic. These practices included clarity in messaging across platforms and public health jurisdictions; pre-emptor alerts of potential measles cases to control and shape the media messaging; and targeted, in-person outreach to engage groups in a culturally competent manner. The Baltimore City Health Department's response drew out a critical need for re-examining infectious disease protocols in the age of social media (e.g. contact notification, quarantine, media sensitivity) and anti-vaccination movements that pose new obstacles to government intervention. The benefits and challenges of greater connectivity between providers, patients, and public health officers are discussed. © The Author 2016.

    We report a measles outbreak in two Portuguese health regions (Algarve and Lisbon and the Tagus Valley) since February 2017, and which by 31 May resulted in 28 confirmed cases, of which 16 were unvaccinated. Thirteen cases were healthcare workers. One unvaccinated teenager died. Genotype B3 was identified in 14 cases from both regions. This outbreak occurs after 12 years without endemic measles transmission, and in a context of high measles vaccination coverage and immunity. This article is copyright of The Authors, 2017.
