    Rubella virus causes a relatively benign disease in most cases, although infection during pregnancy can result in serious birth defects. An effective vaccine has been available since the early 1970s and outbreaks typically do not occur among highly vaccinated (≥2 doses) populations. Nevertheless, considerable inter-individual variation in immune response to rubella immunization does exist, with single-dose seroconversion rates ~95 %. Understanding the mechanisms behind this variability may provide important insights into rubella immunity. In the current study, we examined associations between single nucleotide polymorphisms (SNPs) in selected cytokine, cytokine receptor, and innate/antiviral genes and immune responses following rubella vaccination in order to understand genetic influences on vaccine response. Our approach consisted of a discovery cohort of 887 subjects aged 11-22 at the time of enrollment and a replication cohort of 542 older adolescents and young adults (age 18-40). Our data indicate that SNPs near the butyrophilin genes (BTN3A3/BTN2A1) and cytokine receptors (IL10RB/IFNAR1) are associated with variations in IFNγ secretion and that multiple SNPs in the PVR gene, as well as SNPs located in the ADAR gene, exhibit significant associations with rubella virus-specific IL-6 secretion. This information may be useful, not only in furthering our understanding immune responses to rubella vaccine, but also in identifying key pathways for targeted adjuvant use to boost immunity in those with weak or absent immunity following vaccination.

    Full Text Available Recent outbreaks of measles in the Americas have received news and popular attention, noting the importance of vaccination to population health. To estimate the potential increase in immunization coverage and reduction in days at risk if every opportunity to vaccinate a child was used, we analyzed vaccination histories of children 11-59 months of age from large household surveys in Mesoamerica.Our study included 22,234 children aged less than 59 months in El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Child vaccination cards were used to calculate coverage of measles, mumps, and rubella (MMR and to compute the number of days lived at risk. A child had a missed opportunity for vaccination if their card indicated a visit for vaccinations at which the child was not caught up to schedule for MMR. A Cox proportional hazards model was used to compute the hazard ratio associated with the reduction in days at risk, accounting for missed opportunities.El Salvador had the highest proportion of children with a vaccine card (91.2% while Nicaragua had the lowest (76.5%. Card MMR coverage ranged from 44.6% in Mexico to 79.6% in Honduras while potential coverage accounting for missed opportunities ranged from 70.8% in Nicaragua to 96.4% in El Salvador.

  5. When, and how, should we introduce a combination measles-mumps-rubella (MMR) vaccine into the national childhood expanded immunization programme in South Africa?

    This article briefly reviews the history and epidemiology of measles, mumps and rubella disease and the case for introducing combination measles-mumps-rubella (MMR) vaccine into the national childhood immunization schedule in South Africa. Despite adopting the World Health Organization's Measles Elimination strategy in 1996 and achieving a significant decrease the incidence of measles, added effort is needed in South and southern Africa to reach the goal to eliminate endogenous spread measles. Mumps is still common disease of childhood and while there are few sequelae, even the rare complications are important in large populations. Congenital rubella syndrome is seldom reported, but it is estimated that of the million or so children born every year in South Africa over 600 infants are affected to some degree by rubella infection. The naturally acquired immunity to rubella in women of childbearing age in South Africa has been estimated at over 90%, so that introducing a rubella containing vaccine in childhood may paradoxically increase the proportion of girls reaching puberty still susceptible to rubella. The elimination of endogenous measles and rubella is being achieved in many countries in South America, and despite the recent measles epidemic, must still be seriously considered for South and southern Africa. Current constraints and potential steps needed to reach the goal in South Africa are discussed.

    Two doses of measles-mumps-rubella (MMR) strategy has been recommended by World Health Organization and is also widely adopted in many countries. In order to provide the evidence for perfecting the immunization strategy of MMR, this study evaluated the safety and immunogenicity of MMR with different two-dose schedule in infants. 280 participants were enrolled and randomly allocated to Group 1 (first dose at 8 months) or Group 2 (first dose at 12 months), and both groups administered the second dose at 10 months later. Solicited local and general symptoms after each vaccination with MMR were mild and infrequent in all participants of two groups. After administration of the first dose of MMR, seropositive rates were 100% in both groups for measles, 89.3% in Group 1 and 87.1% in Group 2 for mumps (P=0.578), 92.0% in Group 1 and 92.9% in Group 2 (P=0.393). The seropositive rates of mumps decreased significantly (from >86% to measles and rubella. All children get the positive titer for three vaccines in two groups after given the second dose MMR, higher seroconversion rate was found for mumps both in two groups (71.7% vs 77.2%, P=0.370). In conclusion, this study indicated that the MMR was well tolerated and immunogenic against measles, mumps and rubella with schedule of first dose both at 8 months and 12 months age. Our findings strongly supported that two doses of MMR can be introduced by replacing the first dose of MR in current EPI with MMR at 8 months age and the second dose at 18 months in China.

    Public debate over the safety of the trivalent measles, mumps and rubella (MMR) vaccine and the drop in vaccination rates in several countries persists despite its almost universal use and accepted effectiveness. We carried out a systematic review to assess the evidence of unintended effects (beneficial or harmful) associated with MMR and the applicability of systematic reviewing methods to the field of safety evaluation. Eligible studies were comparative prospective or retrospective on healthy individuals up to 15 years of age, carried out or published by 2003. We identified 120 articles satisfying our inclusion criteria and included 22. MMR is associated with a lower incidence of upper respiratory tract infections, a higher incidence of irritability, similar incidence of other adverse effects compared to placebo and is likely to be associated with benign thrombocytopenic purpura (TP), parotitis, joint and limb complaints and aseptic meningitis (mumps Urabe strain-containing MMR). Exposure to MMR is unlikely to be associated with Crohn's disease, ulcerative colitis, autism or aseptic meningitis (mumps Jeryl-Lynn strain-containing MMR). The design and reporting of safety outcomes in MMR vaccine studies, both pre- and post-marketing, are largely inadequate. The evidence of adverse events following immunization with MMR cannot be separated from its role in preventing the target diseases.

    Recently, a number of outbreaks of measles and mumps have occurred within the UK and Europe. Healthcare workers (HCWs) are at risk of contracting and transmitting disease to patients and staff. To examine this risk at the point of entry to healthcare, we assessed the serological results of new HCWs presenting for pre-placement clearance without evidence of measles-mumps-rubella (MMR) immunity between 1 April 2010 and 31 March 2012. Overall rates of serological positivity to MMR across all age groups were 88·2%, 68·8% and 93·9%, respectively. With regard to measles and mumps, there were statistically significant decreases in the percentage of HCWs born after 1980 that had positive serology (P outbreak within this cohort of HCWs appears low.

    Recent mumps outbreaks have evoked concerns of decreasing mumps immunity among adolescents and adults, including US military recruits subject to differing mumps immunization policies. To compare mumps incidence and to assess initial measles, mumps and rubella seropositivity, we conducted a cohort study among recruits from 2000 to 2004. Mumps incidence in the targeted MMR and universal MMR cohorts was 4.1 and 3.5 per 100,000 person-years, respectively, giving an incidence rate ratio of 1.16 (P=0.67). Measles, mumps, and rubella seropositivity was 84.6%, 89.5%, and 93.2%, respectively. Among recruits with measles and rubella immunity, 92.8% were mumps immune. These findings support the policy of targeting MMR immunization based upon measles and rubella serology alone.

    There are notable inter-individual variations in vaccine-specific antibody responses in vaccinated children. The aim of our study was to investigate whether early-life environmental factors and adaptive immune maturation prior and close to measles-mumps-rubella (MMR) immunization relate to magnitudes of vaccine-specific antibody titers. In the FARMFLORA birth cohort, including both farming and non-farming families, children were immunized with the MMR vaccine at 18 months of age. MMR vaccine-induced antibody titers were measured in plasma samples obtained at 36 months of age. Infants' blood samples obtained at birth, 3-5 days and at 4 and 18 months of age were analyzed for T- and B-cell numbers, proportions of naive and memory T and B cells, and fractions of putative regulatory T cells. Multivariate factor analyses show that higher anti-MMR antibody titers were associated with a lower degree of adaptive immune maturation, that is, lower proportions of memory T cells and a lower capacity of mononuclear cells to produce cytokines, but with higher proportions of putative regulatory T cells. Further, children born by cesarean section (CS) had significantly higher anti-measles titers than vaginally-born children; and CS was found to be associated with delayed adaptive immunity. Also, girls presented with significantly higher anti-mumps and anti-rubella antibody levels than boys at 36 months of age. These results indicate that delayed adaptive immune maturation before and in close proximity to immunization seems to be advantageous for the ability of children to respond with higher anti-MMR antibody levels after vaccination.

    Information on antibody persistence after aerosol revaccination with MMR components is limited. Thus, antibody titers were determined in 283 adult participants in a MMR vaccine trial 12 months after revaccination. One group had received aerosolized Triviraten vaccine while two other groups received either injected Triviraten or MMR II vaccine. Both MMR vaccines contained the same rubella strain, but different measles and mumps strains. Seropositivity to measles persisted in 98% of aerosolized vaccine recipients, 92% of injected Triviraten, and 95% of injected MMR II. All participants in the three groups retained seropositivity to rubella, while less than 50% remained seropositive to mumps. Copyright © 2010 Elsevier Ltd. All rights reserved.

    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.

    In a previous study on booster vaccination, we reported that two aerosolized MMR vaccines were as safe and immunogenic as injectable vaccines containing the same antigens. We now present results of antibody persistence one year after immunization. To assess the antibody persistence for measles, mumps, and rubella one year following booster immunization. We performed clinical and serological follow-up of participants in a previous study of Mexican children aged 6-7years, in which participants were randomized to four groups receiving, by aerosolized or by injection, the MMR SII vaccine (Serum Institute of India), or the MMR II (Merck Sharp & Dhome). We evaluated the antibody persistence by PRN test for measles and by ELISA for rubella and mumps. The occurrence of clinical events was evaluated via periodic visits of a nurse team to children's schools and homes. Of the 260 initial participants, 241 completed one-year follow-up. There were only statistically significant differences in baseline seropositivity for mumps. One year after immunization, seropositivity in all groups was 100% for measles and rubella. The seropositivity rank for mumps was from 90.3% for the injected vaccine MMR II to 96.6% for vaccine MMR SII applied by aerosol; these differences were not statistically significant. With exception of the aerosolized vaccine MMR SII for the geometric mean titer (GMT) for measles, all study groups presented declination of GMT for the three viruses. The difference between the aerosolized vaccines MMR SII and MMR RII was statistically significant for mumps antibodies. Only mild clinical events were identified. Under conditions of no endemic transmission for measles and rubella, and of low circulation of mumps virus, school-aged children remained seropositive to the three viruses one year following booster immunization.

    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.

    Healthcare workers (HCW) have high exposure to infectious diseases, some of which, such as rubella, are vaccine-preventable. The aim of this study was to determine the immunity of HCW against rubella. We performed a seroprevalence study using a self-administered survey and obtained blood samples to determine rubella Immunoglobulin G (IgG) antibody levels in HCW during preventive examinations by five Primary Care Basic Prevention Units and six tertiary hospitals in Catalonia. Informed consent was obtained. IgG was determined using an antibody capture microparticle direct chemiluminometric technique. The odss ratio (OR) and 95% confidence intervals (CI) were calculated. Logistic regression was made to calculate adjusted OR. Of 642 HCW who participated (29.9% physician, 38.8% nurses, 13.3% other health workers and 18% non-health workers), 46.6% were primary care workers and 53.4% hospital workers. Of total, 97.2% had rubella antibodies. HCW aged 30–44 years had a higher prevalence of antibodies (98.4%) compared with HCW aged history of vaccination (97.3% vs. 96.8%, P 0.82). Seroprevalence of rubella antibodies is high in HCW, but workers aged <30 years have a higher susceptibility (5.5%). Vaccination should be reinforced in HCW in this age group, due to the risk of nosocomial transmission and congenital rubella. PMID:24356729

    Single-nucleotide polymorphisms (SNPs) in candidate immune response genes were evaluated for associations with measles- and rubella-specific neutralizing antibodies, interferon (IFN)-γ, and interleukin (IL)-6 secretion in two separate association analyses in a cohort of healthy immunized subjects. We identified six SNP associations shared between the measles-specific and rubella-specific immune responses, specifically neutralizing antibody titers (DDX58), secreted IL-6 (IL10RB, IL12B), and secreted IFN-γ (IFNAR2, TLR4). An intronic SNP (rs669260) in the antiviral innate immune receptor gene, DDX58, was significantly associated with increased neutralizing antibody titers for both measles and rubella viral antigens post-MMR vaccination (p values 0.02 and 0.0002, respectively). Significant associations were also found between IL10RB (rs2284552; measles study p value 0.006, rubella study p value 0.00008) and IL12B (rs2546893; measles study p value 0.005, rubella study p value 0.03) gene polymorphisms and variations in both measles- and rubella virus-specific IL-6 responses. We also identified associations between individual SNPs in the IFNAR2 and TLR4 genes that were associated with IFN-γ secretion for both measles and rubella vaccine-specific immune responses. These results are the first to indicate that there are SNP associations in common across measles and rubella vaccine immune responses and that SNPs from multiple genes involved in innate and adaptive immune response regulation may contribute to the overall human antiviral response.

    Whether or not to vaccinate one's child is one of the first health-related decisions parents have to make after their child's birth. For the past 20 years, the share of parents choosing not to immunize their children has increased in many countries, for various reasons. Among these, rumors affirming that vaccinations contain dangerous chemicals or might trigger severe chronic diseases have negatively affected parental attitudes towards pediatric immunizations, particularly the vaccination against measles, mumps and rubella (MMR), raising a number of public health concerns. The primary aim of this qualitative study is to understand what drives parents' decision, giving special attention to vaccination literacy and psychological empowerment in such a context. Twenty individual semi-structured interviews were conducted in the Canton of Ticino (Switzerland) between January and June 2014. Participants were either mothers or fathers of children less than 1 year old living in Switzerland. An inductive thematic analysis was performed to identify the main themes with regard to vaccination literacy and psychological empowerment in the MMR vaccination decision-making. Parents' reports yielded four main themes: (a) the paradox of the free choice, referring to the misinterpretation of current vaccination policies; (b) giving up the power, pointing at the outcomes of a low perceived competence; (c) a far-reaching decision, reflecting the importance attributed to the MMR choice and the different levels of impact the decision can have; (d) the demand for shared-decision making, referring to the parental needs in relation to the child's healthcare provider. Understanding what drives parents' management of their children's immunization schedule in terms of vaccination literacy and psychological empowerment can help health professionals to communicate more effectively with parents in order to facilitate an informed decision, and stakeholders to design tailored health education

    Circulating immune complexes which contained rubella-specific immunoglobulins were detected in 21 out of 63 subjects with congenital rubella and in 39 out of 65 subjects vaccinated with attenuated rubella virus, but in none of 43 subjects susceptible to rubella or 87 subjects with remote naturally acquired immunity to rubella. The presence or level of circulating immune complexes and the presence of rubella-specific complexes did not correlate with conventional serum rubella hemagglutination inhibition antibody titers. In the group with congenital infection, the presence of specific complexes many years after birth was associated with late-emerging clinical problems involving several organ systems. In vaccinates, the presence of specific complexes was associated with a higher incidence of side reactions. Two-thirds of the vaccinates and all of those revaccinated showed specific immune complexes as late as 8 months after immunization. PMID:7085069

    Healthcare workers (HCW) have high exposure to infectious diseases, some of which, such as rubella, are vaccine-preventable. The aim of this study was to determine the immunity of HCW against rubella. We performed a seroprevalence study using a self-administered survey and obtained blood samples to determine rubella Immunoglobulin G (IgG) antibody levels in HCW during preventive examinations by five Primary Care Basic Prevention Units and six tertiary hospitals in Catalonia. Informed consent was obtained. IgG was determined using an antibody capture microparticle direct chemiluminometric technique. The odss ratio (OR) and 95% confidence intervals (CI) were calculated. Logistic regression was made to calculate adjusted OR. Of 642 HCW who participated (29.9% physician, 38.8% nurses, 13.3% other health workers and 18% non-health workers), 46.6% were primary care workers and 53.4% hospital workers. Of total, 97.2% had rubella antibodies. HCW aged 30-44 years had a higher prevalence of antibodies (98.4%) compared with HCW agedrubella antibodies is high in HCW, but workers agedrubella.

    Conclusions: In the absence of a routine rubella immunization program, the high level of rubella seropositivity suggests rubella virus transmission in Namibia, yet 15% of pregnant Namibian women remain susceptible to rubella. The introduction of rubella vaccine will help reduce the risk of rubella in pregnant women and CRS in infants.

    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

    We sought to explore the clinical variables associated with the loss of rubella immunity during pregnancy and to determine if these changes are linked to obstetrical complications. This is a case-control study in which women were identified whose rubella antibody titers were equivocal or non-immune and compared to those who had retained immunity. Two hundred and eighty-five cases were identified and compared to the same number of controls using Student's t test, Mann-Whitney U-test or Fisher's exact test. Univariate and multivariate logistic regressions were employed. Subjects with diminished immunity were more likely to have public insurance and higher gravidity with a trend toward increased tobacco use. Diminished rubella immunity was not associated with adverse obstetrical outcomes, including preterm birth and pre-eclampsia and is likely not a risk factor for these pregnancy outcomes. While no adverse pregnancy outcomes were associated with a loss of rubella immunity, women with greater number of pregnancies appear to lose their immunity to rubella. This relationship needs to be explored further and if proven, revaccination prior to pregnancy may need to be addressed.

  11. Targeting rubella for elimination

    Full Text Available Rubella is an acute, usually mild viral disease. However, when rubella infection occurs just before conception or during the first 8-10 weeks of gestation, it causes multiple fetal defects in up to 90% of cases, known as Congenital Rubella Syndrome (CRS. It may result in fetal wastage, stillbirths and sensorineural hearing deficit up to 20 weeks of gestation. Rubella vaccine (RA 27/3 is highly effective and has resulted in elimination of rubella and CRS from the western hemisphere and several European countries. Review of several studies documents the duration of protection over 10-21 years following one dose of RA27/3 vaccination, and persistent seropositivity in over 95% cases. Studies in India show seronegativity to rubella among adolescent girls to vary from 10% to 36%. Although due to early age of infection resulting in protection in the reproductive age group, incidence of rubella in India is not very high. However, due to severity of CRS coupled with introduction of RCV in private sector and in some of the states which is likely to lead to sub-optimal coverage and resulting higher risk of rubella during pregnancy in the coming decades, it is imperative to adopt the goal of rubella elimination. As in order to control measles, the country has adopted strategy of delivering second dose of measles through measles campaigns covering children 9 months to 10 years of age in 14 states, it is recommended to synergize efforts for elimination of rubella with these campaigns by replacing measles vaccine by MR or MMR vaccine. Other states which are to give second dose of measles through routine immunization will also have to adopt campaign mode in order to eliminate rubella from the country over 10-20 years. Subsequently, measles vaccine can be replaced by MR or MMR vaccine in the national schedule.

    Rubella IgG levels for 157,763 pregnant women residing in Alberta between 2009 and 2012 were analyzed. As there have been no reported cases of indigenous rubella infection in Canada since 2005, there has been a lack of naturally acquired immunity, and the current prenatal population depends almost entirely on vaccine induced immunity for protection. Rubella antibody levels are significantly lower in younger maternal cohorts with 16.8% of those born prior to universal vaccination programs (1971-1980), and 33.8% of those born after (1981-1990) having IgG levels that are not considered protective (rubella containing vaccine. These discordant interpretations generate a great deal of confusion for laboratorians and physicians alike, and result in significant patient follow-up by Public Health teams. To assess the current antibody levels in the prenatal population, latent class modeling was employed to generate a two class fit model representing women with an antibody response to rubella, and women without an antibody response. The declining level of vaccine-induced antibodies in our population is disconcerting, and a combined approach from the laboratory and Public Health may be required to provide appropriate follow up for women who are truly susceptible to rubella infection.

    Cyclical outbreaks of mumps have been noticed across Chandigarh city during winter months. Chandigarh does not provide measles, mumps and rubella (MMR) vaccination in the State immunization schedule. Epidemiological shift in age at diagnosis of mumps was noticed with higher incidence in older children and adults. Increased occurrence of complications can be predicted with this age shift. Silent burden of rubella with serious outcomes in newborns further strengthen the case for MMR vaccine inclusion in routine immunization program of Chandigarh.

    Rubella is a mild infection of childhood and young adults with 75% of cases occurring in age group 15-45 years. In unvaccinated populations, rubella usually occurs in spring with epidemics in 6-9 years cycles. Rubella has devastating effects on growing foetus if contracted by women in the first trimester of pregnancy. Perinatal infection of Rubella contributes to 2-3% of all congenital anomalies. Over the past three decades many resource risk countries have introduced universal or selective immunization programs against rubella with evidence that such interventions reduce the incidence of congenital rubella syndrome. In Pakistan the schedules of the Expanded Program on Immunization (EPI) do not include immunization against rubella and evidence is needed to estimate the risk of congenital rubella with a view to start immunization programmes to combat the menace of Congenital Rubella Syndrome (CRS). Logistically it is easy to add rubella vaccine to the already existing EPI schedules as measles is given on 9th and 15 month with little implications for cost, resulting in great reduction in CRS.

    Rubella and congenital rubella syndrome are highly underreported and neglected in most sub-Saharan countries and vaccination has not yet been incorporated into their national immunization schedules. In this study, we investigated the frequency of immunoglobulin M antibodies against rubella and examined correlations with fertility rates during the period from 2006 to 2014 in Mozambique. We conducted a retrospective analysis of data collected through the routine case-based surveillance system for measles in Mozambique. A total of 7312 serum samples from suspected cases of measles were tested between 2006 and 2014. The median age was 4 years (interquartile range: 1-8 years). Of these, 1331 (18.2%) were positive for immunoglobulin M anti-rubella. The highest frequency of rubella was observed within the 5-9-year-old age group (32.6%). The frequency in the age groups Mozambique. Considering that early pregnancy is common in Mozambique, this suggests that, in settings such as ours, the introduction of routine rubella vaccination in children should be accompanied by repeated vaccination campaigns targeting older children and adolescents.

    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 Rubella seropositivity among measles seropositives was 90.4%, significantly (P < 0.001) higher than 72.1% among measles seronegatives. Mumps seropositivity among measles seropositives was 87.0%, significantly (P < 0.001) higher than 62.3% among measles seronegatives. Results were similar for Israeli-born only. Our findings indicate that measles seroprevalence decreased after the last change in vaccination policy and reach sub-optimal level. Until global eradication is reached, a proactive vaccination program to supplement routine childhood vaccination program should be considered in Israel and in other countries.

  1. MMR: risk, choice, chance.

    2004-01-01

    The unfolding of the measles, mumps and rubella (MMR) controversy reveals some of the key features of the cultural climate affecting matters of health and illness in contemporary society. A high level of anxiety around issues of health is reflected in a heightened sense of individual vulnerability to environmental dangers (such as atmospheric pollution, electromagnetic fields, bioterrorism) and in a general aversion to risk, particularly in relation to children. This mood has proved responsive to views sceptical, if not hostile, towards science and medicine and associated professionals, particularly in the sphere of immunization. The result is that uptake of MMR vaccination in the UK has fallen, from a peak of 92% in the mid-1990s to a national level of 82% in 2003 (at the age of two); in London uptake is now less than 75%-much less in some areas-causing a significant risk of outbreaks of measles. In the USA too, the proportion of parents opting out of regulations requiring immunization as a condition of school entry has increased significantly in some areas, though these controversies appear to have had little impact so far in continental Europe.

    This report presents new recommendations adopted in June 2009 by CDC's Advisory Committee on Immunization Practices (ACIP) regarding use of the combination measles, mumps, rubella, and varicella vaccine (MMRV, ProQuad, Merck & Co., Inc.). MMRV vaccine was licensed in the United States in September 2005 and may be used instead of measles, mumps, rubella vaccine (MMR, M-M-RII, Merck & Co., Inc.) and varicella vaccine (VARIVAX, Merck & Co., Inc.) to implement the recommended 2-dose vaccine schedule for prevention of measles, mumps, rubella, and varicella among children aged 12 months-12 years. At the time of its licensure, use of MMRV vaccine was preferred for both the first and second doses over separate injections of equivalent component vaccines (MMR vaccine and varicella vaccine), which was consistent with ACIP's 2006 general recommendations on use of combination vaccines (CDC. General recommendations on immunization: recommendations of the Advisory Committee on Immunization Practices [ACIP]. MMWR 2006;55;[No. RR-15]). Since July 2007, supplies of MMRV vaccine have been temporarily unavailable as a result of manufacturing constraints unrelated to efficacy or safety. MMRV vaccine is expected to be available again in the United States in May 2010. In February 2008, on the basis of preliminary data from two studies conducted postlicensure that suggested an increased risk for febrile seizures 5-12 days after vaccination among children aged 12-23 months who had received the first dose of MMRV vaccine compared with children the same age who had received the first dose of MMR vaccine and varicella vaccine administered as separate injections at the same visit, ACIP issued updated recommendations regarding MMRV vaccine use (CDC. Update: recommendations from the Advisory Committee on Immunization Practices [ACIP] regarding administration of combination MMRV vaccine. MMWR 2008;57:258-60). These updated recommendations expressed no preference for use of MMRV vaccine over

    Significant gaps in immunity to polio, measles, and rubella may exist in adults in Cambodia and threaten vaccine-preventable disease (VPD) elimination and control goals, despite high childhood vaccination coverage. We conducted a nationwide serological survey during November-December 2012 of 2154 women aged 15-39 years to assess immunity to polio, measles, and rubella and to estimate congenital rubella syndrome (CRS) incidence. Measles and rubella antibodies were detected by IgG ELISA and polio antibodies by microneutralization testing. Age-structured catalytic models were fitted to rubella serological data to predict CRS cases. Overall, 29.8% of women lacked immunity to at least one poliovirus (PV); seroprevalence to PV1, PV2 and PV3 was 85.9%, 93.4% and 83.3%, respectively. Rubella and measles antibody seroprevalence was 73.3% and 95.9%, respectively. In the 15-19 years age group, 48.2% [95% confidence interval (CI) 42.4-54.1] were susceptible to either PV1 or PV3, and 40.3% (95% CI 33.0-47.5) to rubella virus. Based on rubella antibody seroprevalence, we estimate that >600 infants are born with CRS in Cambodia annually. Significant numbers of Cambodian women are still susceptible to polio and rubella, especially those aged 15-19 years, emphasizing the need to include adults in VPD surveillance and a potential role for vaccination strategies targeted at adults.

    Congenital rubella syndrome (CRS) accounts for a significant amount of mortality and morbidity in India. Rubella vaccination is not included in our national immunization programme. Occupational exposure of the health care personnel to rubella infection is well known. This study aims to assess the serological status of health care workers against rubella virus in Aravind Eye Care System, Madurai and to follow the immune response in the seronegative individuals after vaccination. A total of 500 female and 81 male workers were enrolled in the study. Blood sample was collected for the analysis of rubella specific IgM and IgG antibodies. The seronegative individuals were vaccinated with monovalent rubella vaccine, RA 27/3. The post-vaccination samples were analysed for the antibody levels and their avidity using enzyme immunoassay. Of the 581 volunteers, 493 were seropositive with good protective immunity and 22 had both IgM and IgG antibodies. Sixty six volunteers (59 females and 7 males) were found to be seronegative to rubella. The seroconversion was observed in all the sixty vaccinated individuals, as seen by the appearance of anti-rubella IgG antibodies by fourth week, reaching the peak protective levels (>20 IU/ml) by third month. There was also a progressive increase in the avidity after vaccination. Nearly 11.4 per cent of the health care workers were found to be seronegative for rubella virus and after vaccination, these volunteers developed a good protective immunity, thereby reducing the risk of contracting the hospital based rubella infection. Therefore, rubella vaccination may be instituted in hospitals for the benefit of health care workers.

    Background The seroepidemiology of rubella virus infection in pregnant women in northern Mexico is largely unknown. We sought to determine the seroprevalence of rubella virus infection in pregnant women in the northern Mexican city of Durango, Mexico. Seroprevalence association with the socio-demographic, clinical and behavioral characteristics of the pregnant women was also investigated. Methods Through a cross-sectional study, we determined the seroprevalence of IgG and IgM anti-rubella virus in 279 pregnant women (mean age 29.17 ± 5.96 years; range 15 - 43 years) attending in a clinic of family medicine using enzyme-linked fluorescent assays. A questionnaire was used to obtain the socio-demographic, clinical and behavioral characteristics of the pregnant women. The association of rubella seropositivity and characteristics of the women was assessed by bivariate and multivariate analyses. Results Anti-rubella IgG antibodies (≥ 15 IU/mL) were found in 271 (97.1%) of the 279 pregnant women examined. None of the 279 pregnant women were positive for anti-rubella IgM antibodies. Multivariate analysis of socio-demographic, clinical and behavioral variables showed that seroreactivity to rubella virus was positively associated with national trips (OR = 7.39; 95% CI: 1.41 - 38.78; P = 0.01), and negatively associated with age (OR = 0.26; 95% CI: 0.06 - 0.99; P = 0.04). Conclusions Rate of rubella immunity in pregnant women in the northern Mexican city of Durango is high. However, nearly 3% of pregnant women are susceptible to rubella in our setting. Risk factors associated with rubella seropositivity found in this study may be useful for optimal design of preventive measures against rubella and its sequelae. PMID:27540439

    2015-01-01

    The World Health Organization had established the achievement and sustainability of very high coverage with two doses of vaccine against measles and at least one against rubella as one of the key strategies for the elimination of both measles and rubella. The current immunization programme in Spain includes the immunization with two doses of combined vaccine against measles, mumps and rubella at 12 months and 3-4 years of age. Since 2000 coverage with first dose is over the target of 95% but the coverage with the second dose remains between 90 and 95%. In 2014, at subnational level three regions had coverage below the objective and only eight regions achieved the objective for the second dose. The challenges and some activities to strengthen the immunization programme in order to achieve the elimination of measles and rubella are discussed.

    Rubella vaccination was implemented nationwide in 1992 in Taiwan. A cross-sectional survey was conducted to determine the age-specific seroprevalence of anti-rubella in female students aged 7-22 years old and women of reproductive age in Taipei County. Seropositivity of anti-rubella antibodies was defined as a serum IgG level > or =10 IU/ml tested by enzyme immunoassay. Information on possible predictors of anti-rubella seronegativity was obtained from structured questionnaire interview. Multivariate-adjusted odds ratios (ORm) with their 95% confidence interval (CI) were derived for each predictor using multiple logistic regression analysis. A total of 826 female students and 318 women were recruited. Anti-rubella seropositive rates were 98.3% (282/287), 99.6% (234/235), 96.8% (179/185), 92.4% (110/119), 81.4% (197/242), and 89.5% (68/76) for the age groups of 7-9, 11-13, 15-17, 19-22, 25-33, and 34-44 years old, respectively. Among female students, negative serology for rubella antibodies was associated significantly with the age group and foreign nationality of mother, showing ORm (95% CI) of 1.2 (1.06-1.27) for each year increase in age, and 20.9 (6.31-68.97), respectively. Among women at the reproductive age, low maternal education level 91.6 (9.12-920.74), unmarried status 21.2 (6.16-72.89), and no rubella vaccination 98.9 (11.64-840.25) were associated significantly with an increased evidence of seronegativity to rubella. The National Rubella Vaccination Program has led to herd immunity of school girls. However, in order to eradicate the Rubella syndrome, greater effort is required to vaccinate foreign brides in Taiwan.

    Sera and immune globulin (IG) preparations are customarily treated with kaolin before titration of their rubella hemagglutination-inhibiting (HI) antibody in order to rid them of nonspecific inhibitors of hemagglutination. The treatment was shown in this investigation to have no adverse effect on the antibody level of the sera but was found to remove considerable amounts of gamma-globulin from IG preparations. Evidence of this removal was obtained by serological tests, by spectrophotometric determination of protein concentration and by disc electrophoresis. In contrast to kaolin, heparin-manganese chloride (MnCl2) treatment of IG preparations had essentially no effect on the level of antibody globulin by all the criteria used. Heparin-MnCl2-treated IG lots were in these respects similar, if not identical, to their untreated counterparts. Since nonspecific inhibitors associated with the β-lipoprotein fraction of serum are removed by the method employed to fractionate the IG samples, it seems unnecessary to treat the latter in any way for the HI test. No difficulty was encountered in this investigation with several untreated IG lots. Images PMID:4190525

    Full Text Available To determine the presence of rubella immunity among pregnant women attending their first prenatal visit in Jeddah, Saudi Arabia, a retrospective, descriptive, cross-sectional, hospital-based study (prevalence study was undertaken. A total of 10276 women attending prenatal clinics between January 1, 2008, and December 31, 2011 were included. Rubella screening tests (immunoglobulins: IgG and IgM, rubella antibody titer levels, patient age, gravidity, parity, and the number of previous abortions were analyzed. No patients tested IgM positive, and 9410 (91.6% were immune (IgG positive; the remaining 866 (8.4% were susceptible. There were no significant differences in gravidity, parity, or the number of previous abortions between immune and nonimmune groups. In contrast, the immunity rate decreased with increasing age, with a significant difference between the youngest age group (15–19 years and the oldest age group (40–49 years (P=0.0005; odds ratio, 2.86; 95% confidence interval, 1.7–4.7. Rubella immunity among pregnant women was high (91.6% but decreased significantly with increasing age. A possible explanation for this is the change in the rubella vaccination policy in Saudi Arabia in 2002, from 1 dose to 2 doses. In addition, antibody levels begin to decline after vaccination and natural infection.

    This paper reports data concerning the immune status of 252 pregnant women with regard to rubella infection. The inverse haemagglutination was used to titrate rubella virus-antibodies and it was carried out for each pregnant woman on two blood samples, collected at three weeks' interval. Thirty-nine of the 252 pregnant women (15.50%) contracted the infection in the first trimester of pregnancy. Fifty-seven women (22.60%) showed a low degree of protection against the infection while only forty-five women had a protective rubella virus-antibody titre. Finally, 111 of the 252 (44.60%) pregnant women were rubella virus seronegative and therefore susceptible to the infection.

    Full Text Available Abstract Background In the UK public concern about the safety of the combined measles, mumps and rubella [MMR] vaccine continues to impact on MMR coverage. Whilst the sharp decline in uptake has begun to level out, first and second dose uptake rates remain short of that required for population immunity. Furthermore, international research consistently shows that some parents lack confidence in making a decision about MMR vaccination for their children. Together, this work suggests that effective interventions are required to support parents to make informed decisions about MMR. This trial assessed the impact of a parent-centred, multi-component intervention (balanced information, group discussion, coaching exercise on informed parental decision-making for MMR. Methods This was a two arm, cluster randomised trial. One hundred and forty two UK parents of children eligible for MMR vaccination were recruited from six primary healthcare centres and six childcare organisations. The intervention arm received an MMR information leaflet and participated in the intervention (parent meeting. The control arm received the leaflet only. The primary outcome was decisional conflict. Secondary outcomes were actual and intended MMR choice, knowledge, attitude, concern and necessity beliefs about MMR and anxiety. Results Decisional conflict decreased for both arms to a level where an 'effective' MMR decision could be made one-week (effect estimate = -0.54, p Conclusions Whilst both the leaflet and the parent meeting reduced parents' decisional conflict, the parent meeting appeared to enable parents to act upon their decision leading to vaccination uptake.

    There is no published data regarding immunologic response to vaccinations in children with PFAPA syndrome (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis). The aim of this study was to evaluate mumps, measles and rubella immunity in children with PFAPA. 31 children with PFAPA syndrome and 22 healthy children (control group - CG) were recruited to the study. All children were previously vaccinated with one dose of MMR vaccine according to the Polish obligatory vaccination schedule. The patients from both groups were evaluated for anti-measles, anti-mumps and anti-rubella IgG antibodies concentrations (ELISA tests; the reference values for protective antibody levels were 150IU/L, 16RU/L and 11IU/ml respectively). The percentage of patients with protective antibodies levels was as follows: measles - 93.55% of PFAPA and 95.45% of CG patients (p=0.77); mumps - 74.19% of PFAPA and 95.45% of CG patients (p=0.02); rubella - 80.65% of PFAPA and 90.9% of CG patients (p=0.30). Children with PFAPA syndrome present a good response to the measles and rubella component of the MMR vaccine, however immunity against mumps after one dose of MMR may not be sufficient. Further investigation concerning immunity against vaccine-preventable diseases and the safety of vaccinations in children with periodic fever syndromes is required. Copyright © 2016 Elsevier Ltd.

    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.

    Full Text Available ABSTRACT: Rubella is a mild illness that presents with fever a nd rash with the infection occurring sub clinically. Its public health importanc e is due to its teratogenic effects on the growing foetus in the first trimester of pregnancy. There is insufficient data in India with regard to rubella virus immunity in the community. Occupat ional exposure of health care personnel to rubella infection disease requires special attentio n. Hence this study was taken up to analyse the rubella seroprevalence rate according to age, g eographical distribution, socio-economic class among health care personnel. Study design: Cro ss-sectional study. Methodology: 161 subjects aged between 15 to 30 years were given bac kground information about the study and those who provided voluntary and written consent wer e enrolled. Study was conducted in the month of August 2010. Analysis of rubella specific IgG and IgM antibodies was done by ELISA. Results: Among 161 subjects, 88 subjects were from South India, 42 from North India, 19 from Eastern region and 12 were from the western region of India. Serum IgG positivity was the highest 100% in subjects hailing from Western India , followed by 84.2% from Eastern India and 83.3% in subjects from north India. Subjects from S outh India showed the lowest seropositivity of 68.18%. Conclusion: Immunisation of health care personnel against rubella and whole population of India for rubella immunity is necessary

    Non-immune neonates and non-immune pregnant women are at risk of developing rubella, measles and mumps infections, including congenital rubella syndrome. We describe the seroepidemiology of measles, mumps and rubella (MMR) in neonates and pregnant women in Catalonia (Spain). Anti-rubella, anti-measles and anti-mumps serum IgG titres were assessed using enzyme-linked immunosorbent assay (ELISA) tests in 353 cord blood samples from neonates of a representative sample of pregnant women obtained in 2013. The prevalence of protective antibody titres in neonates was 96 % for rubella IgG (≥8 IU/ml), 90 % for measles IgG (>300 IU/ml) and 84 % for mumps IgG (>460 EU/ml). Slightly lower prevalences of protective IgG titres, as estimated from the cord blood titres, were found in pregnant women: 95 % for rubella IgG, 89 % for measles IgG and 81 % for mumps IgG. The anti-measles and anti-mumps IgG titres and the prevalences of protective IgG titres against measles and mumps increased significantly (p rubella IgG titres increased by 3 % (OR = 1.80, p < 0.05) and the MMR vaccination coverage (during childhood) in pregnant women increased by 54 % (OR = 2.09, p < 0.001) from 2003 to 2013. We recommend to develop an MMR prevention programme in women of childbearing age based on mass MMR vaccination or MMR screening and vaccination of susceptible women to increase immunity levels against MMR.

    Full Text Available Background. Congenital and developmental cataracts are leading causes of childhood blindness and severe visual impairment. They may be associated with systemic diseases including congenital heart diseases which are among the major causes of morbidity and mortality in childhood. The pattern of systemic comorbidities seen in children diagnosed with cataract in Calabar, Nigeria, was studied. Methods. A retrospective review was conducted on the children who had cataract surgery between 2011 and 2012. Diagnosis of the systemic condition was documented. Results. A total of 66 children were recruited for the study. Cardiac disease was seen in 26 children (39.9%, followed by delayed milestone in 16 (24.2%, intellectual disability in 14 (21.2%, deafness in 11 (16.7%, epilepsy in 4 (6.1%, and physical handicap in 3 (4.5% of them. Clinically confirmed Congenital Rubella Syndrome was seen in 30 (45% of the children. The pattern of CHD seen was as follows: patent ductus arteriosus in 16 (24.2% followed by ventricular-septal defect in 5 (7.6%, atrial-septal defect in 3 (4.5%, and pulmonary stenosis in 2 (3%. Conclusion. Systemic comorbidities, especially cardiac anomalies, are common among children with cataract in Nigeria. Congenital Rubella Syndrome may be a prominent cause of childhood cataract in our environment. Routine immunization of school girls against rubella is advocated as a measure to mitigate this trend.

    Rubella in early pregnancy bears a high risk for congenital defects (e.g., cataracts, hearing loss, and heart disease) and for long-term sequelae in the newborn. Despite implementation of vaccination programs in many regions, the threat of devastating consequences from congenital rubella virus infection remains and careful screening of maternal immune status before and during pregnancy helps to reduce the risk. This study compared the performance of the Elecsys Rubella IgG assay with that of other assays routinely used for screening. Samples from 1,090 women undergoing routine antenatal care were tested using the Elecsys and Enzygnost Rubella IgG assays and the hemagglutination inhibition test. Samples with hemagglutination inhibition titers of 90.0%) than the other immunoassays (78.6 to 82.4%). The Elecsys assay reported significantly higher rubella virus IgG levels than the other immunoassays across the whole set of 1,090 samples, with the largest bias and deviation from limits of agreement in Bland-Altman analysis. In conclusion, the Elecsys assay is highly sensitive and specific with regard to qualitative results and suitable for routine automated screening. However, given the considerable variation between quantitative results from different immunoassays, testing methods should be documented and the same assay used throughout an individual's antenatal follow-up wherever possible.

  5. Extended LTA, TNF, LST1 and HLA gene haplotypes and their association with rubella vaccine-induced immunity.

    Directory of Open Access Journals (Sweden)

    Inna G Ovsyannikova

    Full Text Available BACKGROUND: Recent studies have suggested the importance of HLA genes in determining immune responses following rubella vaccine. The telomeric class III region of the HLA complex harbors several genes, including lymphotoxin alpha (LTA, tumor necrosis factor (TNF and leukocyte specific transcript -1 (LST1 genes, located between the class I B and class II DRB1 loci. Apart from HLA, little is known about the effect of this extended genetic region on HLA haplotypic backgrounds as applied to immune responses. METHODOLOGY/PRINCIPAL FINDINGS: We examined the association between immune responses and extended class I-class II-class III haplotypes among 714 healthy children after two doses of rubella vaccination. These extended haplotypes were then compared to the HLA-only haplotypes. The most significant association was observed between haplotypes extending across the HLA class I region, ten-SNP haplotypes, and the HLA class II region (i.e. A-C-B-LTA-TNF-LST1-DRB1-DQA1-DQB1-DPA1-DPB1 and rubella-specific antibodies (global p-value of 0.03. Associations were found between both extended A*02-C*03-B*15-AAAACGGGGC-DRB1*04-DQA1*03-DQB1*03-DPA1*01-DPB1*04 (p = 0.002 and HLA-only A*02-C*03-B*15-DRB1*04-DQA1*03-DQB1*03-DPA1*01-DPB1*04 haplotypes (p = 0.009 and higher levels of rubella antibodies. The class II HLA-only haplotype DRB1*13-DQA1*01-DQB1*06-DPA1*01-DPB1*04 (p = 0.04 lacking LTA-TNF-LST1 SNPs was associated with lower rubella antibody responses. Similarly, the class I-class II HLA-only A*01-C*07-B*08-DRB1*03-DQA1*05-DQB1*02-DPA1*01-DPB1*04 haplotype was associated with increased TNF-alpha secretion levels (p = 0.009. In contrast, the extended AAAACGGGGC-DRB1*01-DQA1*01-DQB1*05-DPA1*01-DPB1*04 (p = 0.01 haplotype was found to trend with decreased rubella-specific IL-6 secretion levels. CONCLUSIONS/SIGNIFICANCE: These data suggest the importance of examining both HLA genes and genes in the class III region as part of the extended haplotypes useful in

    Perfluoroalkyl substances (PFASs) are highly persistent chemicals that might be associated with asthma and allergy, but the associations remain unclear. Therefore, this study examined whether pre- and postnatal PFAS exposure was associated with childhood asthma and allergy. Measles, mumps, and rubella (MMR) vaccination in early life may have a protective effect against asthma and allergy, and MMR vaccination is therefore taken into account when evaluating these associations. In a cohort of Faroese children whose mothers were recruited during pregnancy, serum concentrations of five PFASs - Perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA) - were measured at three timepoints (maternal serum in pregnancy week 34-36 and child serum at ages 5 and 13 years) and their association with immunoglobulin E (IgE) (cord blood and at age 7 years) and asthma/allergic diseases (questionnaires at ages 5 and 13 years and skin prick test at age 13 years) was determined. A total of 559 children were included in the analyses. Interactions with MMR vaccination were evaluated. Among 22 MMR-unvaccinated children, higher levels of the five PFASs at age 5 years were associated with increased odds of asthma at ages 5 and 13. The associations were reversed among MMR-vaccinated children. Prenatal PFAS exposure was not associated with childhood asthma or allergic diseases regardless of MMR vaccination status. In conclusion, PFAS exposure at age 5 was associated with increased risk of asthma among a small subgroup of MMR-unvaccinated children but not among MMR-vaccinated children. While PFAS exposure may impact immune system functions, this study suggests that MMR vaccination might be a potential effect-modifier.

    Seventy-seven patients with acute lymphoblastic leukemia (ALL) who were in complete remission and whose therapies had been stopped for at least 6 months before enrollment in this study were retrospectively analyzed regarding their antibody status for measles, mumps, and rubella, with the aim to demonstrate the seropositivity rate after treatment in the authors' group. Each patient's serum samples were analyzed by enzyme-linked immunosorbent assay (ELISA) method to determine the antibody titers before and after immunization. Measles serology was available in 77 children; 45 (58%) were seronegative. Initial ages of measle-seronegative patients were statistically lower than those of seropositive cases (median 3.29 versus 4.91 years, respectively). Mumps serology was available in 76 children; 36 (47%) were seronegative. Mumps-seropositive cases tended to have more frequent previous history of infection than seronegative cases (55.0% versus 28.6%, respectively, P = .05). Rubella serology was available in 76 children, and 20 (26.3%) were seronegative. It was determined that initial ages of rubella-seronegative patients were statistically lower than those of seropositive cases (median 3.03 versus 4.32 years, respectively). The authors concluded based on the results of their study that at a median of 3.31 years after completion of chemotherapy for ALL, the majority of cases had antibody levels lower than protective values for measles (58.4%); however, these values were 47.3% for mumps and 26.3% for rubella. Seroconversion rates after measles (55%) and mumps vaccination (57.1%) were still low. However, in the available cases, relatively adequate response to rubella vaccination (92.3%) was observed.

    Immunisation decision making is not a straightforward process for parents. Many factors influence parental decision making on whether they immunise their child with the measles, mumps and rubella (MMR) vaccine. The feasibility study described in this article provides insight into influencing factors associated with decisions regarding the immunisation of children by parents. The study findings suggest that the practice nurse is a credible source of information for parents seeking informed decision making. At a time when the incidence of measles and mumps is rising in the UK, the provision of appropriate information by the practice nurse has the potential to increase uptake of the MMR vaccine.

    Herd immunity blocks the transmission of measles, mumps and rubella in a population group when the prevalence of positive serologic results (p) is higher than a critical value (p c), known as the herd immunity threshold. A new preventive strategy should be developed in order to achieve the elimination of measles, rubella and mumps in Europe based on the serological assessment of herd immunity levels in different population groups. This strategy could detect population groups without herd immunity (p herd immunity and prevent outbreaks. The serological assessment of herd immunity levels in Catalonia, Spain, showed that herd immunity had not been established for measles and mumps in schoolchildren (5-9 years of age) and youths/younger adults (15-29 years of age), and that the additional vaccination coverage required to establish herd immunity in these groups was 1-7%. The new preventive strategy should be used to detect priority population groups for preventive and surveillance activities in European countries.

    To assess US availability and use of measles-mumps-rubella (MMR) vaccination documentation for refugees vaccinated overseas. We selected 1500 refugee records from 14 states from March 2013 through July 2015 to determine whether overseas vaccination records were available at the US postarrival health assessment and integrated into the Advisory Committee on Immunization Practices schedule. We assessed number of doses, dosing interval, and contraindications. Twelve of 14 (85.7%) states provided data on 1118 (74.5%) refugees. Overseas records for 972 (86.9%) refugees were available, most from the Centers for Disease Control and Prevention's Electronic Disease Notification system (66.9%). Most refugees (829; 85.3%) were assessed appropriately for MMR vaccination; 37 (3.8%) should have received MMR vaccine but did not; 106 (10.9%) did not need the MMR vaccine but were vaccinated. Overseas documentation was available at most clinics, and MMR vaccinations typically were given when needed. Further collaboration between refugee health clinics and state immunization information systems would improve accessibility of vaccination documentation.

    The Italian National Plan of Measles and Rubella Elimination 2010-2015 has deferred the objective to reduce congenital rubella syndrome (CRS) to rubella among women in childbearing-age. In Puglia region, MMR vaccine coverage is 93% in newborns (cohort 2010; one dose), 85% in children 5-6 years old and 77% in adolescents (cohort 2005 and 1997, respectively; two doses). Combining available seroepidemiological data and results of a survey on the attitude towards rubella vaccination and rubella testing before pregnancy, we could estimate that 5.7% of Apulian women in childbearing-age are currently susceptible to rubella infection. The regional infectious disease routine notification system reported no cases of CRS and rubella in pregnancy in 2001-2010 period. The inconsistency among the mentioned data triggered the evaluation of the reliability of disease reporting. We performed a retrospective case-finding for the years 2003-2011. We scanned the regional hospital discharge registry to identify hospitalizations for rubella in pregnancy and CRS and retrieve individual records. We also searched for clinical history of CRS mothers in the delivery assistance certificate registry. We identified one CRS, two confirmed and four suspected congenital infections, and seven cases of rubella in pregnancy. Passive surveillance of CRS and rubella in pregnancy appears not to be reliable in the light of strengthening rubella elimination strategies.

    To investigate whether the incorporation of rubella vaccine into immunization programmes in developing countries is economically justified. A MEDLINE search was conducted for articles published between 1970 and 2000 that dealt with economic analyses of rubella and rubella-containing vaccines. The Eastern Mediterranean, South-East Asia, and Africa regional Index Medicus databases and the LILACS database for Latin America and the Caribbean were also searched. For developed countries, five cost- benefit analyses of rubella vaccine and five of measles-mumps-rubella vaccine as well as two cost-effectiveness analyses were found. For developing countries, five cost analyses and five cost-benefit analyses were found. All the cost-benefit analyses had a benefit:cost ratio greater than 1 and the cost-effectiveness studies indicated that rubella immunization was a cost-effective means of reducing the impact of congenital rubella syndrome. However, the methodologies were not standardized. The data support the inclusion of rubella vaccine in the immunization programmes of both developing and developed countries and indicate economic benefits comparable to those associated with hepatitis B vaccine and Haemophilus influenzae type b vaccine. More studies should be carried out on costs for care and immunization using standardized methodologies and locally obtained information.

    A combined measles-mumps-rubella-varicella (MMRV) vaccine is expected to facilitate universal immunization against these 4 diseases. This study was undertaken to synthesize current research findings of the immunogenicity and safety of MMRV in healthy children.We searched PubMed, Embase, BIOSIS Previews, Web of Science, Cochrane Library, and other databases through September 9, 2014. Eligible randomized controlled trials (RCTs) were selected and collected independently by 2 reviewers. Meta-analysis was conducted using Stata 12.0 and RevMan 5.3.Twenty-four RCTs were included in qualitative synthesis. Nineteen RCTs compared single MMRV dose with measles-mumps-rubella vaccine with or without varicella vaccine (MMR + V/MMR). Similar seroconversion rates of these 4 viruses were found between comparison groups. There were comparable geometric mean titers (GMTs) against mumps and varicella viruses between MMRV group and MMR + V/MMR group. MMRV group achieved enhanced immune response to measles component, with GMT ratio of 1.66 (95% confidence interval [CI] 1.48, 1.86; P measles/rubella-like rash (relative risks 1.44-1.45) in MMRV groups.MMRV had comparable immunogenicity and overall safety profiles to MMR + V/MMR in healthy children based on current evidence.

    We undertook a national paediatric seroprevalence survey of measles, mumps and rubella (MMR) in Singapore to assess the impact of the national childhood immunization programme against these three diseases after introduction of the trivalent MMR vaccine in 1990. The survey involved 1200 residual sera of Singapore residents aged 1-17 years collected from two hospitals between 2008 and 2010. The overall prevalence of antibodies against measles, mumps and rubella was 83∙1% [95% confidence interval (CI) 80∙9-85∙1], 71.8% (95% CI 69∙1-74∙2) and 88∙5% (95% CI 86∙6-90∙2), respectively. For all three diseases, the lowest prevalence was in children aged 1 year (47∙8-62∙3%). The seroprevalence of the vaccinated children declined over time. The national MMR immunization programme is effective in raising the herd immunity of the childhood population, although certain age groups are more susceptible to infection, in particular, those who are not eligible for vaccination at age <15 months.

    In populations vaccinated with two doses of combined measles-mumps-rubella vaccine (MMR), the serum levels of antibodies against measles depend on the vaccination schedule, time elapsed from the last dose and the area-specific epidemiological situation. Variables measuring "schedule" are age at first and second doses of MMR and intervals derived from that. Changes in vaccination schedules have been made in Portugal. The specific objectives of this study were to measure the association between those potential determinants and the concentration of measles-specific IgG antibodies, after the second dose of MMR. Convenience samples of three Portuguese birth cohorts were selected for this study (41, 66 and 60 born, respectively, in 2001-2003, 1990-1993 and 1994-1995). Geometric mean concentrations (GMC) for measles IgG were, respectively, 934, 251 and 144mIU/ml; pmeasles-IgG serum concentration decreased with time since last vaccination (waning immunity) and was not influenced by any other component of vaccination schedule, namely age at vaccination with the second dose of MMR. Waning levels of measles antibodies have been observed elsewhere but not as fast as it was observed in Portuguese birth cohorts in this study. Changes in the vaccination schedules might have to be considered in the future.

    Measles outbreaks continue to occur in the United States and are mostly due to infections in returning travelers. To describe how providers assessed the measles immunity status of departing U.S. adult travelers seeking pretravel consultation and to assess reasons given for nonvaccination among those considered eligible to receive the measles, mumps, rubella (MMR) vaccine. Observational study in U.S. pretravel clinics. 24 sites associated with Global TravEpiNet (GTEN), a Centers for Disease Control and Prevention-funded consortium. Adults (born in or after 1957) attending pretravel consultations at GTEN sites (2009 to 2014). Structured questionnaire completed by traveler and provider during pretravel consultation. 40 810 adult travelers were included; providers considered 6612 (16%) to be eligible for MMR vaccine at the time of pretravel consultation. Of the MMR-eligible, 3477 (53%) were not vaccinated at the visit; of these, 1689 (48%) were not vaccinated because of traveler refusal, 966 (28%) because of provider decision, and 822 (24%) because of health systems barriers. Most MMR-eligible travelers who were not vaccinated were evaluated in the South (2262 travelers [65%]) or at nonacademic centers (1777 travelers [51%]). Nonvaccination due to traveler refusal was most frequent in the South (1432 travelers [63%]) and in nonacademic centers (1178 travelers [66%]). These estimates could underrepresent the opportunities for MMR vaccination because providers accepted verbal histories of disease and vaccination as evidence of immunity. Of U.S. adult travelers who presented for pretravel consultation at GTEN sites, 16% met criteria for MMR vaccination according to the provider's assessment, but fewer than half of these travelers were vaccinated. An increase in MMR vaccination of eligible U.S. adult travelers could reduce the likelihood of importation and transmission of measles virus.

    Full Text Available Introduction of MMR vaccine was believed to have resulted in a decline in the incidence of measles, mumps and rubella infections. However, recent reports suggest the re-emergence of mumps infection worldwide in the vaccinated populations. It was proposed that the reason for this re-emergence was poor efficacy of MMR vaccine. The present study was aimed to investigate mumps infection in MMR vaccinated and non-vaccinated populations in Chennai, India. Blood samples were collected from acute mumps cases (n=74, 42<12 yr age, 54% males and investigated for IgM antibody against mumps, IgG antibody against measles, mumps and rubella viruses by ELISA. Sixty seven (91% patients had received MMR vaccine. All the 67 vaccinated cases were positive for parotitis, and mumps IgM. However, only 10 (15% were positive for IgG. All samples (100% were positive for rubella and measles IgG. These findings showed the occurrence of mumps infection among MMR vaccinated individuals in Chennai, India. The MMR vaccine failed to generate anti-mumps IgG. The reason may be low vaccine efficacy of the mumps component of the MMR vaccine used.

    Data on vaccination effects in children chronically exposed to heavy metals are extremely scarce. This study aims to investigate the immune responsiveness to measles, mumps, and rubella (MMR) vaccination in children from an e-waste recycling area. 378 healthy children from Guiyu (exposed group) and Haojiang (reference group) were surveyed. Blood lead (Pb) levels were measured by graphite furnace atomic absorption. Titers of antibodies against MMR were quantified by ELISA. Blood Pb levels of children from the exposed group were significantly higher than those from the reference group (5.61μg/dL vs. 3.57μg/dL, pe-waste recycling area should be modified.

    Rhode Island law requires that rubella serological screening be done for most female marriage license applicants. To evaluate the effect of the law, 203 rubella-susceptible women detected through premarital screening over a four-month period in 1978 were surveyed. Of those responding, 37% had been immunized, 21% were pregnant or infertile, and 42% were eligible for immunization but had not received vaccine. Premarital immunization occurred most frequently when physicians advised and directly offered vaccine. A survey of primary care physicians indicated that 24% immunized none of their rubella-susceptible patients detected by premarital screening.

    In order to assess the immunity to rubella infection in Dongguan, China, we conducted a seroprevalence survey on rubella and used ELISA to measure rubella-specific IgG in serum samples. A total of 1,017 individuals aged 0-59 years were selected by multistage cluster sampling. Among them, 904 (88.9%) were seropositive for rubella. Two groups (20-29 and ≥40 years) had seropositivity rates of rubella immunization rates were higher in those aged rubella-protective antibody levels. Our results suggest that in the study area, women of childbearing age had a greater serological susceptibility to rubella. Additional vaccinations for rubella of susceptible young adults should be considered, particularly in women of childbearing age.

    Rubella is a highly contagious viral disease which is mostly threatens to women of reproductive age. Existent live attenuated vaccines are effective enough, but have some drawbacks and are unusable for a certain group of people, including pregnant women and people with AIDS and other immunodeficiency. Thereby the development of alternative non-replicating, recombinant vaccines undoubtedly is needed. This review discusses the protein E1 and E2 role in formation of immune response and perspectives in development of new generation recombinant vaccines using them.

    Full Text Available Abstract Background Congenital rubella syndrome (CRS is associated with several negative outcomes, including autism spectrum disorders (ASDs. The objective of this study was to estimate the numbers of CRS and ASD cases prevented by rubella vaccination in the United States from 2001 through 2010. Methods Prevention estimates were calculated through simple mathematical modeling, with values of model parameters determined from published literature. Model parameters included pre-vaccine era CRS incidence, vaccine era CRS incidence, the number of live births per year, and the percentage of CRS cases presenting with an ASD. Results Based on our estimates, 16,600 CRS cases (range: 8300-62,250 were prevented by rubella vaccination from 2001 through 2010 in the United States. An estimated 1228 ASD cases were prevented by rubella vaccination in the United States during this time period. Simulating a slight expansion in ASD diagnostic criteria in recent decades, we estimate that a minimum of 830 ASD cases and a maximum of 6225 ASD cases were prevented. Conclusions We estimate that rubella vaccination prevented substantial numbers of CRS and ASD cases in the United States from 2001 through 2010. These findings provide additional incentive to maintain high measles-mumps-rubella (MMR vaccination coverage.

    The suggestion that multi-antigen vaccines might overload the immune system has led to calls for single antigen vaccines. In 2003 we showed that rather than an increase there appeared to be a reduced risk of severe bacterial infection in the three months following Measles, Mumps and Rubella vaccine (MMR). The present analysis of illnesses in a general population is based on an additional 10 years of data for bacterial infections and also includes admissions with viral infections. Analyses were carried out using the self-controlled case-series method and separately for bacterial and viral infection cases, using risk periods of 0-30 days, 31-60 days and 61-90 days post MMR vaccine. An analysis was also carried out for those cases which were given MMR and Meningococcal serogroup C (MCC) vaccines concomitantly. A reduced risk was seen in the 0-30-day period for both bacterial infection (relative incidence=0.68, 95% CI 0.54-0.86) and viral infections (relative incidence=0.68, 95% CI 0.49-0.93). There was no increased risk in any period when looking at combined viral or bacterial infections or for individual infections with the single exception of an increased risk in the 31-60 days post vaccination period for herpes infections (relative incidence=1.69, 95% CI 1.06-2.70). For the children given Meningococcal group C vaccines concomitantly no significantly increased risk was seen in either the bacterial (relative incidence=0.54, 95% CI 0.26-1.13) or viral cases (relative incidence=0.46, 95% CI 0.11-1.93). Our study confirms that the MMR vaccine does not increase the risk of invasive bacterial or viral infection in the 90 days after the vaccination and does not support the hypothesis that there is an induced immune deficiency due to overload from multi-antigen vaccines.

    The Danish childhood vaccination programme offers protection against measles, mumps, and rubella (MMR). Nevertheless, many children appear to be unvaccinated according to the national registers. The aim of this study was to estimate the MMR1 vaccination coverage based on a medical record review of children whose vaccination status is negative according to the register-based data. We conducted a cross-sectional study of 19 randomly selected general practices in the Central Denmark Region including 1,712 children aged 18-42 months. The practices received a registration form listing children with a negative MMR1 vaccination status in the register-based data. The general practices then validated the children's vaccination status by medical record review. In total, 94% of the children had been vaccinated according to the medical records in general practice compared with 86% according to the register-based data. Of the 246 children who were unvaccinated according to the register-based data, 135 (55%) had been vaccinated according to the medical records. This discrepancy was due mainly to administrative reimbursement errors. The MMR1 vaccination coverage in Denmark seems to be considerably higher than reflected in national registers. Using medical record review to re-assess the vaccination status revealed that most of the supposedly unvaccinated children had, in fact, been vaccinated.

    Measles, Mumps, and Rubella (MMR) are vaccine preventable viral infections, which cause significant mortality and morbidity globally. Increased incidence rates of these infectious diseases are observed in young adults. Information on seroprevalence data on MMR in India is limited. The objective of this study was to determine the prevalence of IgG antibodies against MMR among young adults. This was a descriptive cross-sectional study involving 192 healthy college students from Maharshi Dayanand College, Mumbai. The project was approved by the Institutional Ethics Committee of Haffkine Institute. Between December 2012 and September 2013, blood samples were collected from individuals of age 18-23 years after obtaining written informed consent from them. The quantitative determination of IgG antibodies in serum specimens against MMR was determined using enzyme linked immunosorbent assay. Data on history of vaccination were also collected from participants. Among 192 healthy college students (age 18-23 years), MMR seroprevalence was 91%, 97%, and 88%, respectively. The overall seropositivity of MMR was 79%. The highest level of seronegativity was seen with regards to rubella-specific antibodies in 12% of cases. About 96% of the participants did not know about their vaccination history while none of the participants knew about their history of MMR infections. Despite unknown vaccination status, a majority of college students in our study were found seropositive for all three infections, which indicate natural boosting. However, the proportion of seronegativity for measles and rubella was relatively higher. Especially since the study population belonged to reproductive age group, there is a concern of congenital rubella syndrome in the offspring. Although a larger multicentric study is required to confirm the findings, the results indicate that a dose of measles-rubella (MR) vaccine should be offered to these college students.

  18. Does rubella cause autism: a 2015 reappraisal?

    Full Text Available In the 1970s, Stella Chess found a high prevalence of autism in children with congenital rubella syndrome (CRS, 200 times that of the general population at the time. Many researchers quote this fact to add proof to the current theory that maternal infection with immune system activation in pregnancy leads to autism in the offspring. This rubella and autism association is presented with the notion that rubella has been eliminated in today’s world. CRS cases are no longer typically seen, yet autistic children often share findings of CRS including deafness, congenital heart defects and to a lesser extent visual changes. Autistic children commonly have hyperactivity and spasticity, as do CRS children. Both autistic and CRS individuals may develop type 1 diabetes as young adults. Neuropathology of CRS infants may reveal cerebral vasculitis with narrowed lumens and cerebral necrosis. Neuroradiologic findings of children with CRS show calcifications, periventricular leukomalacia, and dilated perivascular spaces. Neuroradiology of autism has also demonstrated hyperintensities, leukomalacia and prominent perivascular spaces. PET studies of autistic individuals exhibit decreased perfusion to areas of the brain similarly affected by rubella. In both autism and CRS, certain changes in the brain have implicated the immune system. Several children with autism lack antibodies to rubella, as do children with CRS. These numerous similarities increase the probability of an association between rubella virus and autism.Rubella and autism cross many ethnicities in many countries. Contrary to current belief, rubella has not been eradicated and globally affects up to 5% of pregnant women. Susceptibility continues as vaccines are not given worldwide and are not fully protective. Rubella might still cause autism, even in vaccinated populations.

    Sporadic cases of rubella infection are reported each year in France due to insufficient vaccination coverage. Rubella virus is a very unstable enveloped RNA virus. For this reason, transportation and storage of samples collected for its detection require particular conditions. The genetic stability of rubella virus has allowed the development of very effective vaccines. During the recent rubella outbreaks in Algeria and Tunisia, an unusual high rate of encephalitis was reported. The role of the laboratory is crucial in the management of rubella infection during pregnancy. Rubella serological results must be interpreted with caution. Congenital rubella is a severe disease that should already be eliminated thanks to a very effective vaccine that has been developed. All women of childbearing age should be vaccinated. Rubella vaccination of an unknowingly pregnant woman is not an indication for abortion.

    Conclusion: In our previous study, we had recommended to screen for susceptibility to rubella before marriage, which is no longer required since more than 99% of vaccinated girls showed immunity at the time of marriage. However, as sustainability of immunity after rubella vaccination is usually less than immunity due to illness, we recommend screening for rubella protective antibody every few years.

    Mumps is an acute viral infectious disease characterized by fever and swelling and tenderness of one or more salivary glands, usually the parotid gland. Since 1976, the German Standing Committee on Vaccination (STIKO) has recommended a mumps vaccination as part of the routine immunization schedule in former West Germany. In East Germany, the vaccination was only introduced in 1991 after reunification. In the preceding decades, no comprehensive surveillance system existed in Germany. However, for East Germany and the successional federal states of former East Germany, data on mumps incidence are available from different Eastern surveillance systems for the time period 1968-2012. According to these data, the incidence of mumps has dropped from > 200 cases/100,000 annually in the pre-vaccine era to currently epidemiology and the increase of outbreaks among adolescents and young adults, the implementation of a nationwide mandatory notification was initiated and came into effect in March 2013. Mandatory notification enables the early detection of outbreaks and obtainment of comprehensive data for evaluation of the immunization program in place. Regarding the long-term prevention of mumps in Germany, it is hoped that--as part of the measles and rubella elimination effort--coverage rates for the second MMR dose among children will increase nationwide above 95% and existing vaccination gaps among adults will be closed.

    Leukocyte preparations from children with documented evidence of MMR vaccination and confirmed diagnosis of autism were examined by several assays designed to target multiple regions of the measles virus genome sequence. No sample was found positive by any method. The assays applied were highly sensitive, specific and robust in nature, and were based on the amplification of measles virus RNA transcripts by real-time quantitative RT-PCR (QRT-PCR) as well as by conventional RT-PCR-nested PCR. The assays applied were potentially able to detect measles virus RNA down to single figure copy numbers per reaction. The amount of total nucleic acid extract of leukocytes subjected to various measles virus-specific investigations was several fold higher than minimally required of a sample where measles virus persistence is well documented. This study failed to substantiate reports of the persistence of measles virus in autistic children with development regression.

    The potential to strengthen routine immunization (RI) services through supplementary immunization activities (SIAs) is an important benefit of global measles and rubella elimination and polio eradication strategies. However, little evidence exists on how best to use SIAs to strengthen RI. As part the 2012 Nepal measles-rubella and polio SIA, we developed an intervention package designed to improve RI processes and evaluated its effect on specific RI process measures. The intervention package was incorporated into existing SIA activities and materials to improve healthcare providers' RI knowledge and practices throughout Nepal. In 1 region (Central Region) we surveyed the same 100 randomly selected health facilities before and after the SIA and evaluated the following RI process measures: vaccine safety, RI planning, RI service delivery, vaccine supply chain, and RI data recording practices. Data collection included observations of vaccination sessions, interviews with the primary healthcare provider who administered vaccines at each facility, and administrative record reviews. Pair-matched analytical methods were used to determine whether statistically significant changes in the selected RI process measures occurred over time. After the SIA, significant positive changes were measured in healthcare provider knowledge of adverse events following immunization (11% increase), availability of RI microplans (+17%) and maps (+12%), and awareness of how long a reconstituted measles vial can be used before it must be discarded (+14%). For the SIA, 42% of providers created an SIA high-risk villages list, and >50% incorporated this information into RI outreach session site planning. Significant negative changes occurred in correct knowledge of measles vaccination contraindications (-11%), correct definition for a measles outbreak (-21%), and how to treat a child with a severe adverse event following immunization (-10%). Twenty percent of providers reported cancelling ≥1 RI

    International migration rapidly increased in the last decade, raising a renewed attention to its impact on public health. We evaluated differences in rubella immunization rate (RIR) between immigrant and Italian women of childbearing age and tried to identify the driving factors causing them. We analyzed data from the Italian behavioral surveillance system PASSI collected in 2011-2015 in a nationally representative sample of residents in Italy. The analysis was performed using log-binomial models to compare RIR between 41,094 Italian women and 3140 regular immigrant women of childbearing age (18-49 years), stratifying the latter by area of origin and length-of-stay in Italy (recent: ≤ 5-years; mid-term: 6-10-years; long-term: > 10-years). Immigrant women showed a RIR of 36.0% compared to 60.2% among Italian women (RIR-ratio = 0.60, 95% confidence interval (CI): 0.57-0.63). Adjusting for demographic characteristics (i.e., sex, age and area of residence), socio-economic factors (i.e., education, occupation, family composition and economic status) and an indicator of the presence of at least one health-risk behavior (i.e., physical inactivity, current cigarette smoking, excessive alcohol consumption and excess weight) did not significantly change this difference (RIR-ratio = 0.56, 95% CI: 0.53-0.59). Recent immigrants (RIR-ratio = 0.47, 95% CI: 0.42-0.53) and immigrants from high migratory pressure countries (HMPC) in sub-Saharan Africa (RIR-ratio = 0.41, 95% CI: 0.31-0.56) and Asia (RIR-ratio = 0.42, 95% CI: 0.33-0.53) showed the greatest differences in RIR compared with Italian women. Differences in RIR between immigrant and Italian women were not explained by different demographic, socioeconomic and health-risk behaviors characteristics. As entitlement to free-of-charge immunization in Italy is universal, regardless of migration status, other informal barriers (e.g., cultural and barriers to information access) might explain lower RIRs in immigrant women

  7. The epidemiology of rubella in the Republic of Ireland.

    1993-07-16

    The trend in notified cases of rubella in the Republic of Ireland from 1950 to 1990 has been downward, with a mean interval of four years between peak periods. Vaccine uptake and antenatal immunity levelled out in the 1980s at 85% and 87%, respectively. One hundred and six cases of congenital rubella were recorded between 1975 and 1990, 66 being reported by paediatricians. The fact that cases of congenital rubella still occur highlights the need for a continued and aggressive immunisation policy, up-to-date and cohort-based data on vaccine uptake, and the introduction of a congenital rubella register.

    Objectives Most developed countries do not have compulsory immunisation requirements, but instead issue recommendations. Although parents are expected to make an informed, autonomous (ie, empowered) decision regarding their children's vaccinations, there is no evidence about how parents' interpret this demand nor on the latitude of their decision-making.

    Rubella virus usually causes a mild fever and rash in children and adults. However, infection during pregnancy, especially during the first trimester, can result in miscarriage, fetal death, stillbirth, or a constellation of congenital malformations known as congenital rubella syndrome (CRS). In 2011, the World Health Organization (WHO) updated guidance on the preferred strategy for introduction of rubella-containing vaccine (RCV) into national routine immunization schedules, including an initial vaccination campaign usually targeting children aged 9 months-15 years . The Global Vaccine Action Plan endorsed by the World Health Assembly in 2012 and the Global Measles and Rubella Strategic Plan (2012-2020) published by Measles and Rubella Initiative partners in 2012 both include goals to eliminate rubella and CRS in at least two WHO regions by 2015, and at least five WHO regions by 2020 (2,3). This report updates a previous report and summarizes global progress toward rubella and CRS control and elimination during 2000-2014. As of December 2014, RCV had been introduced in 140 (72%) countries, an increase from 99 (51%) countries in 2000 (for this report, WHO member states are referred to as countries). Reported rubella cases declined 95%, from 670,894 cases in 102 countries in 2000 to 33,068 cases in 162 countries in 2014, although reporting is inconsistent. To achieve the 2020 Global Vaccine Action Plan rubella and CRS elimination goals, RCV introduction needs to continue as country criteria indicating readiness are met, and rubella and CRS surveillance need to be strengthened to ensure that progress toward elimination can be measured.

    Rubella virus is involved in the pathogenesis of Fuchs heterochromic uveitis and almost all cases in Europe show an active antibody production in the aqueous humor against rubella virus. Herein we report a case of a fully vaccinated patient with common variable immunodeficiency who developed unilateral Fuchs heterochromic uveitis secondary to rubella virus which was proven by intraocular fluid examination. Awareness of rubella associated anterior uveitis should remain also in vaccinated patients, especially those without a fully competent immune system.

    The matched case-control study has been undertook to investigate whether measles, mumps, and rubella (MMR) vaccine may be casually associated with autism in children. Cases were children to 14-year old with diagnosis of core autism or atypical autism. Controls were matched on age, sex and general practice. The 96 cases and 192 controls were included. The study provides strong evidence against association of autism with both MMR and a single measles individual vaccine. Additionally children vaccinated with MMR, regardless of age of vaccination (to 18th, 24th and 36th month of life), had risk equal half of that of single measles vaccinated (for vaccinated to 18th month OR=0.41 95%PU: 0.20-0.85). Our findings confirm that MMR vaccination is not associated with an increased risk of autism in children.

    Habl, Claudia

    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

    Full Text Available BACKGROUND: The reported coverage of the measles-rubella (MR or measles-mumps-rubella (MMR vaccine is greater than 99.0% in Zhejiang province. However, the incidence of measles, mumps, and rubella remains high. In this study, we assessed MMR seropositivity and disease distribution by age on the basis of the current vaccination program, wherein the first dose of MR is administered at 8 months and the second dose of MMR is administered at 18-24 months. METHODS: Cross-sectional serological surveys of MMR antibodies were conducted by collecting epidemiological data in Zhejiang province, China in 2011. In total, 1015 participants were randomly selected from two surveillance sites. Serum MMR-specific immunoglobulin G levels were tested by enzyme-linked immunosorbent assay. The geometric mean titers and seroprevalence with 95% confidence intervals (CIs were calculated by age and gender. Proportions of different dose of vaccine by age by vaccine were also identified. Statistically significant differences between categories were assessed by the Chi-square test. RESULTS: Over 95% seroprevalence rates of measles were seen in all age groups except <7 months infants. Children aged 5-9 years were shown lower seropositivity rates of mumps while elder adolescences and young adults were presented lower rubella seroprevalence. Especially, rubella seropositivity was significantly lower in female adults than in male. Nine measles cases were unvaccinated or unknown vaccination history. Among them, 66.67% (6/9 patients were aged 20-29 years while 33.33% (3/9 were infants aged 8-12 months. In addition, 57.75% (648/1122 patients with mumps were children aged 5-9 years, and 50.54% (94/186 rubella cases were aged 15-39 years. CONCLUSIONS: A timely two-dose MMR vaccination schedule is recommended, with the first dose at 8 months and the second dose at 18-24 months. An MR vaccination speed-up campaign may be necessary for elder adolescents and young adults, particularly

    Rubella causes disease in the fetus. Immunity to rubella is therefore, routinely screened in pregnant women. In this retrospective observational study, we assessed the levels of potential susceptibility to rubella in the population of a north London antenatal clinic. Risk factors for potential susceptibility to rubella and changes in potential susceptibility to rubella over time were studied. Almost all women were screened for potential susceptibility to rubella (99.8%). The majority were predicted to be immune (96.8%). Women booking in later years within the study period showed higher levels of potential susceptibility to rubella. Booking during each subsequent year in the study gave women an odds ratio of 0.91 (CI:0.84, 0.98, P = 0.009) of being predicted to have immunity against rubella. Age was associated with predicted immunity to rubella, with a 5.1% (CI:3.3%, 6.9%, P < 0.001) increased likelihood for every year older. Previous pregnancy was predictive of immunity against rubella with an odds ratio of 1.41 (CI 1.21, 1.61, P = 0.001). Those from a non-white ethnicity were less likely to have antibodies predictive of immunity (OR: 0.730, CI: 0.581, 0.879 P < 0.001). Country of birth was associated with differences in potential susceptibility, with those being born outside of the British Isles having an odds ratio for predicted immunity of 0.63 (CI:0.35,0.91, P = 0.001). Being born in a high-risk country for rubella non-immunity was also a risk factor, giving an odds ratio of predicted immunity to rubella of 0.55 (CI:0.32, 0.77, P < 0.001). © 2017 Wiley Periodicals, Inc.

    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.

    Febrile seizures represent a recognized serious adverse event following measles, mumps, and rubella (MMR) vaccination. We conducted a series of genome-wide association scans comparing children with MMR-related febrile seizures, children with febrile seizures unrelated to vaccination, and controls with no history of febrile seizures. Two loci were distinctly associated with MMR-related febrile seizures, harboring the interferon-stimulated gene IFI44L (rs273259; P = 5.9×10−12 vs. controls; P =1.2×10−9 vs. MMR-unrelated febrile seizures) and the measles virus receptor CD46 (rs1318653; P = 9.6×10−11 vs. controls; P = 1.6×10−9 vs. MMR-unrelated febrile seizures). Furthermore, four loci were associated with febrile seizures in general implicating the sodium channel genes SCN1A (rs6432860; P = 2.2×10−16) and SCN2A (rs3769955; P = 3.1×10−10), a TMEM16 family gene (TMEM16C; rs114444506; P = 3.7×10−20), and a region associated with magnesium levels (12q21.33; rs11105468; P = 3.4×10−11). Finally, functional relevance of TMEM16C was demonstrated with electrophysiological experiments in wild-type and knockout rats. PMID:25344690

    To eliminate the indigenous measles and rubella virus by 2012 in Japan, the strategy fro prevention of measles and rubella prevalence with measles-rubella (MR) vaccine was proposed. Since the vast majority of 1-year old infants are susceptible to measles and rubella, the first MR vaccine, the first MR vaccine should be administered at 1-year old to sustain the herd immunity. Since significant elevation of measles and rubella antibody titers were eliminated in a half of children after the second dose, the second dose of of MR vaccine within 1 year before elementary school entry is the effective maneuver. Moreover, supplement MR vaccination to the teenage group and 20-29 years' group might be necessary, because the mean measles antibody titers in this group were significantly lower compared with those in the older individuals' groups.

    Full Text Available The aseptic meningitis after Measles-Mumps-Rubella vaccine (MMR is a well recognized complication, and different incidences have been observed in several studies. We retrospectively analyzed forty cases of aseptic meningitis, during a large public immunization campaign (1998 in Curitiba, Southern Brazil (590,609 people, admitted in our Service. The vaccine utilized was Leningrad-3-Zagreb mumps strain, Edmonston-Zagreb measles strain, and RA 27#3 rubella strain. In all county, a total number of 87 cases were reported, resulting in a incidence of 1.7 cases per 10,000 given doses . The mean age was 23.7 ± 12.8 years. The female:male ratio was 1.35:1. Severe headache with meningismus (92.5%, fever (87.5%, nausea/vomiting (82.5% were the most common clinical findings. Three cases (7.5% developed mild mumps. All patients underwent cerebrospinal fluid (CSF tap with the following findings: mononuclear pleocytosis from 100 to 500 cells/mm³ in 17 cases (42.5%; 257.5 ± 260.6 cells/mm³; increased protein 28 cases (67.5%; 92.1 ± 76.9 mg/dL; glucose was normal in all cases (56.8 ± 11.2 mg/dL except in 4 (10% cases, which presented less than 44 mg/dL. All serological tests (latex to bacterial meningitis, Cryptococcus, cysticercosis, VDRL and bacteriological cultures were negative. Virus identification were also negative in 8 samples. None of the patients had neurological deficits or related symptoms after one year of onset. We believe the benefit of vaccination clearly outweights the incidence of benign vaccine-associated meningitis.

    Congenital rubella syndrome (CRS) has serious consequences, such as miscarriage, stillbirth, and severe birth defects in infants, resulting from rubella virus infection during pregnancy. However, rubella vaccine has not yet been implemented in Indonesia. This study aimed (1) to estimate the incidence of CRS in Indonesia, (2) describe the clinical features of CRS at our referral hospital, and (3) pilot a CRS surveillance system to be extended to other hospitals. We conducted a 4-month prospective surveillance study of infants aged Indonesia. Conducting hospital-based surveillance of CRS in other hospitals in Indonesia may be appropriate. What is Known: •Congenital rubella syndrome (CRS) has serious consequences in infants resulting from rubella virus infection during pregnancy. •The incidence of CRS in most developed countries has greatly decreased since implementation of rubella vaccination. •Rubella vaccine has not yet been implemented in many developing countries. What is New: •The number of laboratory-confirmed CRS cases among Indonesian infants was high. •Implementation of rubella vaccine into immunization programs in Indonesia is important because of the high number of CRS cases. •Our study highlights the need for ongoing prospective surveillance of CRS in Indonesia.

    Although thorough studies on the immune reponse to rubella have been performed, less attention has been given to the cellular mechanism and mediators that shape the process. Specifically, information concerning the nature ofcytokine patterns involved in the immune response to Rubella vaccination is not avaliable. This study deals with cytokine production patterns of spleen cells from Balb/c mice following vaccination with the Takahashi strain of Rubella vaccine. Mice were injected intraperitonealy with Rubella virus and PBS and 7, 10 or 14 days later, spleen cells were separated and cultured with varying doses of virus, con A or only the medium. ELISA assays were performed on supernatants for measurement of IL-4, INF-gamma and IL-5. LTT (Lymphocyte Transformation Test) was also performed. The data indicate variation in cytokine patterns during the time periods after vaccination. On day 7 a type 1 pattern was observed. The LTT response was also indicative of CMI (Cell Mediated Immunity) response on the 7th and 14th days while a transient suppression on day 10 was observed. These results indicate a time dependent cytokine response with variation ultimately leading o a dominant type 1 (Ti) cytokine response.

    A two-year Vermont program identified 494 (7 per cent) of 6,982 premarital female serologies that were seronegative (less than 1:8) to rubella by hemagglutination inhibition (HI) titer. All 494 susceptible patients and their physicians were notified of their results by letter. The State Health Department received reports that a total of 194 (39 per cent) of the susceptible patients had received rubella vaccinations as a result of their notifications. Intensive follow-up of susceptibles appears to be important factor in the success of premarital rubella screening programs. PMID:4025661

    Despite substantial progress towards measles and rubella control, outbreaks continue to threaten elimination goals worldwide. This paper aims to document progress towards the global eradication of measles and rubella. In particular, it investigates the major challenges faced by Italy in reaching the elimination goals. A review of the most important literature was carried out. Furthermore, a systematic review of the scientific literature on measles and rubella in the Italian setting was performed for the period 2000-2016. In the National Plan 2010-2015, Italy renewed its commitment to eliminate measles and rubella by 2015. However, Italy recently experienced a high measles burden (2,205 cases in 2013, 1,694 in 2014). Between June 2015 and May 2016, 515 cases were reported, accounting for 28% all cases in Europe. Immunization coverage decreased in recent years, with no Region reaching the 95% target. The systematic review included a total of 175 papers, with an upward trend in the number of published articles, which demonstrates an increasing interest in the field of measles and rubella. The review highlights the need to improve the commitment of the Italian Regions to the elimination goals; to promote Supplementary Immunization Activities (SIAs); to improve the communication skills of health care workers; to improve the health literacy of citizens; and to enhance integrated measles and rubella surveillance. Elimination of measles and rubella in Italy will require a substantial improvement in both commitment of the 21 Regions and activity of the whole country towards the WHO goals.

    Full Text Available Purpose. To report a case of unilateral optic neuritis following Measles-Mumps-Rubella (MMR vaccination. Methods. A 30-year-old female developed unilateral optic neuritis five days after a Measles-Mumps-Rubella (MMR booster vaccination. The patient displayed unilateral involvement, with severe visual loss. However, visual acuity improved significantly after four days of intravenous steroid therapy with 500 mg/day of methylprednisolone. Conclusions. Optic neuritis is one of the rare complications associated with the mumps, measles, and rubella vaccine. It may be a toxic reaction to the nonviral component of the vaccine, but the exact etiology is unknown. Postvaccination neuritis is generally bilateral and usually affects children. In adults, unilateral optic neuritis is usually correlated with multiple sclerosis (MS.

    Scholars have examined how news media frame events, including responsibility for causing and fixing problems, and how these frames inform public judgment. This study analyzed 281 newspaper articles about a controversial medical study linking the measles, mumps, and rubella (MMR) vaccination with autism. Given criticism of the study and its potential negative impact on vaccination rates across multiple countries, the current study examined actors to whom news media attributed blame for the MMR-vaccine association, sources used to support those attributions, and what solutions (e.g., mobilizing information), if any, were offered. This study provides unique insight by examining the evolution of these attributions over the lifetime of the controversy. Findings emphasize how news media may attribute blame in health risk communication and how that ascription plays a potentially vital role in shaping public behavior. Theoretical and practical implications are discussed.

    Full Text Available A rubella outbreak occurred in Anqing city of Anhui province, China, from February to July of 2012, and a total of 241 clinically diagnosed or lab-confirmed patients were reported. The highest number of rubella cases during this outbreak was recorded in teenagers between 10 and 19 years of age who had not previously received the rubella vaccine. Genotyping results indicated that the genotype 2B rubella virus (RV was responsible for the outbreak. However, a phylogenetic analysis showed that the genotype 2B RVs isolated in Anqing City were not related to 2B RVs found in other cities of Anhui province and in other provinces of China, thus providing evidence for importation. After importation, the transmission of Anqing RVs was interrupted owing to an effective immunization campaign against rubella, suggesting the timeliness and effectiveness of contingency vaccination. Strengthening rubella surveillance, including the integration of epidemiologic information and laboratory data, is a vital strategy for rubella control and elimination. In addition, except for routine immunization, targeted supplementary immunization activities aimed at susceptible groups according to sero-epidemiological surveillance data also play a key role in stopping the continuous transmission of rubella viruses and in preventing further congenital rubella syndrome cases.

    Full Text Available National Institute of Communicable Diseases (NICD has been engaged in rubella testing for serodiagnosis of the infection and screening for immunity status. The compiled and evaluated data of the work done on rubella testing for the past fifteen years has been presented here to show the trend and changing scenario of the disease in Delhi. Blood samples were from 7424 patients referred to NICD, Delhi for serodiagnosis of congenital Rubella s yndrome (CRS in malformed babies, in utero rubella infection in women and immunity status of pregnant women and women with bad obstetric history. They were tested for rubella IgG and/or rubella IgM antibodies using commercially available reagents and kits. The data from the 15 years of testing was then compiled and evaluated. From the available data it was seen that immunity status against rubella in childbearing age group of women increased steadily from 49% in 1988 to 87% in 2002. Reported cases of CRS at NICD are also on the decline over the time period. There is periodic indication of high incidence of rubella in the year 1988; 1991and 1998 as the reported cases of acute rubella infection in childbearing age group is high during these years.

    Full Text Available Context: Rubella is a mild self-limiting disease all over the world; nevertheless, it is of significant public health importance due to its teratogenic effect of congenital rubella syndrome. Rubella vaccine is currently not included in the national immunization program in India. Rubella-specific IgG in the unvaccinated population is a marker of previous rubella infection. Rubella IgG estimation in children will provide data for initiation and necessary modification to the immunization strategy. Aims: In this background, this study was conducted with an aim to know the age-specific susceptibility of acquiring rubella infections and future risk of congenital rubella syndrome (CRS among girls. Settings and Design: This was a community-based, observational study. Participants and Methods: The study was conducted at a randomly selected rural area Mavoor Panchayath of Kozhikode District, Kerala, among adolescent girls. The estimation of rubella-specific IgG antibody was done by quantitative enzyme-linked immunosorbent assay method. IgG titer value of >15 IU was taken positive, 8-15 IU as equivocal, and <8 IU as negative. Statistical Analysis Used: Statistical analysis was performed using Statistical program for Social science version 16 for Windows. Chi-square test was applied to find out significant difference and Fisher′s exact test wherever applicable. Results: The data and blood sample collection was done from 250 girls. The mean IgG titer was 151.93 ± 128.78 IU, and as per the criteria, 68.3% were positive, 28.5% were negative, and 3.2% were equivocal. At this age, majority (68.3% of the girls get protection by natural infection without any vaccine. Some girls (32% may remain susceptible to infection during adulthood and pregnancy. Conclusions: Natural rubella infection was widely prevalent among child population and at this age. An immunization policy recommending rubella-containing vaccine is highly desirable to prevent rubella and CRS.

    Objective:To evaluate the prevalence of toxoplasmosis and rubella among pregnant women at Ouagadougou in Burkina Faso. Methods: All patient sera were tested for rubella and toxoplasmosis anti-IgG using commercial ELISA kits (PlateliaTM Rubella IgG and Platelia™Toxo IgG). The presence of anti-rubella and anti-toxoplasmosis IgM in serum samples was tested using commercial ELISA kits Platelia Rubella IgM and Platelia Toxo IgM. Results:Among all the pregnant women tested for toxoplasmosis and rubella, their prevalence were 20.3%and 77.0%, respectively. Pregnant women in the age group of 18-25 years showed the highest frequency of anti-toxoplasmosis (34.5%) and anti-rubella IgG (84.6%). The prevalence of anti-toxoplasma and anti-rubella IgG decreased between 2006 and 2008 from 32.7%to 12.1%and 84.6%to 65.0%, respectively. There was no significant association between age and the mean titer of anti-toxoplasmosis IgG among pregnant women. Conclusions: The diagnosis of toxoplasmosis and rubella is necessary in pregnant women in Burkina Faso because of the low immunization coverage rate of rubella and the high level of exposure to these two infections which can be harmful to the newborn if contracted by women before the third trimester of pregnancy.

    Full Text Available Abstract Background Congenital rubella syndrome (CRS can be prevented with appropriate vaccination programs. The prevalence rates of rubella and CRS in Iran are unknown; therefore, the risk of exposure in pregnant women is not clear. The prevalence of CRS in the pre-vaccine period can be estimated by evaluating the proportion of children in the population with sensorineural hearing loss attributable to rubella. Methods This was a case-control study to estimate prevalence of CRS in Tehran (Iran by evaluating the proportion of children with sensorineural hearing loss attributable to rubella. The study used rubella antibody titer as an indicator, and compared the prevalence of rubella antibody between children with and without sensorineural hearing loss. Using these findings, the proportion of cases of sensorineural hearing loss attributable to rubella was estimated. Results A total of 225 children aged 1 to 4 years were entered into the study (113 cases and 112 controls. There was a significant difference between cases and controls with regard to rubella antibody seropositivity (19.5% vs. 8.9%, respectively, odds ratio = 2.47, 95% CI = 1.04–5.97. The proportion of sensorineural hearing loss cases attributable to rubella was found to be 12%, corresponding to a CRS prevalence of 0.2/1000. Conclusion The prevalence of CRS was approximately 0.2/1000 before rubella vaccination in Iran, Moreover; the results suggest that implementation of appropriate rubella vaccination programs could potentially prevent about 12% of cases of sensorineural hearing loss in Iranian children. This data could potentially be used as baseline data, which in conjunction with an appropriate method, to establish a surveillance system for rubella vaccination in Iran. An appropriate surveillance system is needed, because the introduction of a rubella vaccine without epidemiological data and an adequate monitoring program could result in the shifting of rubella cases to higher

    Rubella is a vaccine-preventable, mild rash-inducing viral disease with complications that include a spectrum of birth defects in the developing fetus, especially if the infection is acquired in the early months of pregnancy. Consequently, the primary objective of global rubella control programs is prevention of congenital rubella infection and associated birth defects. Despite the availability of safe and effective vaccines, and the elimination of the rubella virus in many developed countries, substantial commitment to rubella control has not been demonstrated in developing countries. This study appraises immunity to rubella, and consequently makes appropriate recommendations aimed at facilitating effective control. A cross-sectional sero-surveillance study was carried out among defined 272 consenting ante-natal clinic attendees in south-western, Nigeria. Prevalence rates of 91.54% and 1.84% were recorded for the anti-rubella virus (anti-RV) IgG and IgM, respectively. Also, 90.7% and 92.3% of the women aged ≤30 years and >30 years, respectively, had detectable anti-RV IgG. No significant association (p = 0.94) was recorded between anti-RV IgG detection and age of the women. Previous exposure and susceptibility of significant fraction of the population to rubella infection were confirmed. Considerable political commitment and promotion of free rubella immunization specifically for women with childbearing potential were recommended.

  19. New recommended schedule for active immunization of normal infants and children.

    1986-09-19

    A large, randomized, double-blind trial has made available sufficient data to recommend the simultaneous administration of combined measles-mumps-rubella (MMR), diphtheria and tetanus toxoids and pertussis (DTP), and oral poliovirus (OPV) vaccines to all children 15 months old or older who are eligible to receive these vaccines. In this trial, serologic response and clinical reaction rates following primary immunization with MMR were compared in a test group of 405 children given MMR simultaneously with DTP and OPV and a control group of 410 children given MMR followed by doses of DTP and OPV vaccine 2 months later. Seroconversion rates to each MMR component exceeded 96% in both groups, and the geometric mean titers achieved against the other 6 antigens also were similar in both groups. Rates of most of the common vaccine-associated clinical reactions to DTP and MMR were not augmented by simultaneous administration of these 2 vaccines. Some minor side effects were reported more frequently in the simultaneous-administration group, but these difference were judged to be related to artifacts of the study design rather than to differences in the safety of the 2 vaccine schedules. Data from the Center for Disease Control's Monitoring System for Adverse Events Following Immunization have been reviewed, particularly the information from Idaho, Louisiana, and Tennessee, where policies to administer MMR, DTP, and OPV simultaneously have been in effect for periods ranging from several months to years. The evidence suggests no increased risk of reactions associated with the simulaneous administration of these antigens. The overall implications of simultaneous administartion have not been fully defined, but it is anticipated that implementation of this new schedule will result in at least 3 benefits: a decrease in the number of health care provider visits required for immunization during the 2nd year of life, and accompanying decrease in costs, and an increase in the

    Rubella infection though a mild infection, may cause foetal death or a variety of congenital anomalies. Multiple sero-surveys confirmed that 5-10% women are unexposed to natural or vaccinated rubella virus and remain susceptible to rubella infection. The current study was conducted in 600 girls, aged 18-24 y from Symbiosis International University (SIU), Pune, India to assess their sero-status against rubella infection and to estimate the immunogenicity of rubella vaccine in achieving sero-protective antibody titres. Prior to administration of a single i.m. dose of rubella vaccine (R-vac®) to eligible participants, blood sample (pre-vaccination) was collected. During the 4-6 weeks observation period, adverse events were noted. Then, a second blood sample (post-vaccination) was collected. Significant increase was noted in sero-protection response, viz., 98.6% (post-vaccination) vis-à-vis 66.5% (pre-vaccination); Geometric mean titer (GMT) was significantly higher post-vaccination. Effective measures to introduce rubella vaccination on a larger scale need to be undertaken. An immunization policy with mandatory rubella vaccination for all girls in the reproductive age group and its inclusion in national immunization schedule is highly desirable.

    Routinely, the first measles, mumps, and rubella (MMR) vaccine dose is given at 14 months of age in the Netherlands. However, during a measles epidemic in 2013-2014, MMR vaccination was also offered to 6-14-month-olds in municipalities with measles, their infant's saliva was tested for measles-specific antibodies. The vaccine effectiveness (VE) against laboratory-confirmed and self-reported measles was estimated using Cox regression, with VE calculated as 1 minus the hazard ratio. Three vaccinated and 10 unvaccinated laboratory-confirmed cases occurred over observation times of 106631 and 23769 days, respectively. The unadjusted VE against laboratory-confirmed measles was 94% (95% confidence interval [CI], 79%-98%). After adjustment for religion and sibling's vaccination status, the VE decreased to 71% (-72%-95%). For self-reported measles, the unadjusted and adjusted VE was 67% (40%-82%) and 43% (-12%-71%), respectively. Infants vaccinated between 6 and 14 months of age had a lower risk of measles than unvaccinated infants. However, part of the effect was caused by herd immunity, since vaccinated infants were more likely to be surrounded by other vaccinated individuals.

    Between 24 March and 31 July 2009, 342 clinically diagnosed cases of rubella were notified in five municipalities in Republika Srpska, Bosnia and Herzegovina. Fourteen cases were laboratory-confirmed by positive IgG against rubella virus. Four virus isolates were obtained and identified as genotype 2B strains, with one isolate differing by a single mutation in the region of the E1 gene. This ongoing outbreak revealed gaps in the immunisation programme during the war in BiH (1992-1995) and highlights the need to revise legislation to permit immunisation of children above 14 years of age with measles, mumps, rubella (MMR) vaccine and to introduce supplemental immunisation activities.

    Rubella virus outbreaks usually occur when a large numbers of susceptible individuals accumulate. The disease presents clinically with fever and maculopapular rash. The present study reports the investigation of rubella outbreak in a modern and well-planned village near Chandigarh, North India. The blood samples were collected from 39 cases with febrile rash and from 15 age and sex matched healthy controls residing in the same locality and subjected for the detection of Rubella IgM and IgG antibodies by Enzyme linked immunosorbent assay. The throat swabs, urine and blood samples from acute cases were also collected and subjected to RT-PCR using the primers targeting the E1 region. The genetic characterization of the rubella virus was carried out to identify the circulating genotypes. In the present outbreak, 13 laboratory confirmed cases were reported. Rubella IgM antibodies were detected in 12/39 (30.7%) patients. Rubella RNA could be detected in 83.3% (5/6) of urine, 22.2% (2/9) of throat swabs, and 8.3% (1/12) of blood samples. The rubella genotype responsible for the present outbreak was identified as genotype 1a. This outbreak highlights the need for the introduction of rubella vaccine in the National Immunization Programme of India to prevent outbreaks and to aim towards the eradication of this disease. This study reports the presence of genotype 1a in North India for the first time and stresses the need for further molecular work to identify the circulating strains of the virus.

    One combined measles-mumps-rubella (MMR) vaccine without Human Serum Albumin (HSA) is currently licensed in the USA (M-M-R II; Merck, USA) and another has been developed (Priorix™ [MMR-RIT, GSK, Belgium]). In this follow-up study, children from USA or Puerto Rico, who had received one dose of M-M-R II or MMR-RIT at 12-15 months of age in the primary study (NCT00861744), were followed-up for 2 y post-vaccination. Anti-measles and anti-rubella antibodies were measured using Enzyme-Linked Immunosorbent Assay (ELISA), and anti-mumps antibodies using ELISA and plaque reduction neutralization (PRN) assays. Serious adverse events (SAEs) were recorded during the entire follow-up. The according-to-protocol (ATP) persistence cohort included 752 children (M-M-R II = 186, MMR-RIT = 566), who received primary vaccination at a mean age of 12.3 ( ± 0.67) months. 104 children were revaccinated with MMR-containing vaccines; therefore, serology results for timepoints after revaccination were excluded from the analysis. Seropositivity for measles (Year 1≥ 98.3%; Year 2≥ 99.4%) and rubella (Year 1≥ 98.9%; Year 2 = 100%) remained as high at Year 2 as at Day 42. Similarly, seropositivity for mumps determined by ELISA (Year 1≥ 90.1%; Year 2≥ 94.1%) and PRN assays (Year 1≥ 87.5%; Year 2≥ 91.7%) persisted. Thirty-three SAEs were recorded in 23 children; 2 SAEs (inguinal adenitis and idiopathic thrombocytopenic purpura) and one SAE (febrile convulsion) were considered as potentially related to MMR-RIT and M-M-R II, respectively. This study showed that antibodies against measles, mumps and rubella persisted for up to 2 y post-vaccination with either MMR vaccine in children aged 12-15 months, and that both vaccines were well-tolerated during the follow-up period.

    Introduction. Rubella infection has the potential of causing severe fetal birth defects collectively called congenital rubella syndrome (CRS) if the mother is infected early in pregnancy. However, little is known about rubella and CRS epidemiology in Nigeria and rubella vaccines are still not part of routine childhood immunization in Nigeria. Methods. Analysis of confirmed cases of rubella in Abia State, Nigeria from 2007 to 2011 detected through Abia State Integrated Disease Surveillance and Response system. Results. Of the 757 febrile rash cases, 81(10.7%) tested positive for rubella immunoglobulin M (IgM). New rubella infection decreased from 6.81/1,000,000 population in 2007 to 2.28/1,000,000 in 2009 and increased to 6.34/1,000,000 in 2011. The relative risk of rubella was 1.5 (CI [0.98-2.28]) times as high in females compared to males and 1.6 times (CI [0.90-2.91]) as high in rural areas compared to urban areas. Eighty six percent of rubella infections occurred in children less than 15 years with a high proportion of cases occurring between 5 and 14 years. Conclusion. Rubella infection in Abia State, Nigeria is predominantly in those who are younger than 15 years old. It is also more prevalent in females and in those living in rural areas of the state. Unfortunately, there is no surveillance of CRS in Nigeria and so the public health impact of rubella infection in the state is not known. Efforts should be made to expand the rubella surveillance in Nigeria to incorporate surveillance for CRS.

    To determine the susceptibility of female eye hospital staff to rubella infection and the potential risk for hospital-based rubella outbreaks. A prospective cohort study on the seroprevalence of rubella IgG antibodies was conducted at three large eye hospitals in Coimbatore, Madurai and Tirunelveli, Tamil Nadu, India, where young children with eye abnormalities attributable to congenital rubella are treated. A total of 1000 female hospital employees aged 18-40 years agreed to participate and gave written informed consent. The proportions of rubella-seronegative women were: 11.7% at Coimbatore, with a 95% confidence interval (CI) of 8.1-16.5; 15% at Madurai (95% CI = 12.3-18.1), and 20.8 at Tirunelveli (95% CI = 14.7-28.6). For the entire cohort the proportion seronegative was significantly higher among married women (21.5%) than among single women (14.0%) (P = 0.02). Rates of seronegativity were highest among physicians and lowest among housekeepers. All 150 seronegative women in the study sample accepted a dose of rubella vaccine. These are the first rubella serosurveys to have been reported from eye hospitals in any country. The relatively high rate of susceptibility indicated a risk of a rubella outbreak, and this was reduced by vaccinating all seronegative women. A policy has been established at all three hospitals for the provision of rubella vaccine to new employees. Other hospitals, especially eye hospitals and hospitals in countries without routine rubella immunization, should consider the rubella susceptibility of staff and the risk of hospital-based rubella outbreaks.

    To achieve the goal of eliminating measles and rubella two key strategies have been defined: sustain very low level of population susceptibility and strengthen surveillance system by rigorous case investigation and rapid control measures implementation. Surveillance of measles, rubella and CRS are included into the Spanish Surveillance System (RENAVE); surveillance is mandatory, passive, nationwide and case-based with laboratory information integrated. Information flows from sub national to national level (National Centre for Epidemiology) and then, to the WHO-Europe through ECDC. In the final phase of elimination, good surveillance and documented evidences are keys. Information on epidemiology of measles, rubella and CRS cases and outbreaks, pattern of importation, genotypes circulating and performance of measles and rubella surveillance are required at national and international level. Also all investigated and discarded measles or rubella cases should be reported. Currently the system faces some challenges gathering needed information for documenting the elimination. As long as the disease incidence declines, increases difficulties in identifying clinical measles and rubella because of non-specific prodromal signs and atypical cases. Differential diagnosis for fever and rash including measles and rubella should be performed in all clinical settings. Three clinical specimens must be collected to confirm or discard cases and to allow the virus characterization in order to know the pattern of importation of measles and rubella.

    To determine the proficiency of the Austrian childhood vaccination schedule to induce long lasting seroprotection against vaccine preventable diseases a seroepidemiological study in 348 children between four and eight years of age was conducted. Antibodies against diphtheria, tetanus, pertussis, hepatitis B, measles, mumps and rubella antigens were assessed in children, who had been vaccinated with hexavalent DTaP-HBV-IPV/Hib vaccines at three, four, five months and in the second year of life and/or MMR vaccines in the second year of life at least once, but mostly twice. High seroprotection rates (SPRs) were detected for tetanus (96%) and measles (90%). SPRs regarding diphtheria and mumps were 81% and 72%, respectively. Rubella-SPRs were 68% in females and 58% in males. Hepatitis B-antibody levels ≥10 mIU/mL were present in 52%; antibodies against pertussis were detected in 27% of the children. SPRs for measles and rubella depended on the interval since last vaccination; mumps-antibodies were significantly lower after one MMR-vaccination only. Antibodies against diphtheria, tetanus and pertussis depended on the interval since last vaccination while HBs-antibodies did not. The low levels of antibodies 1-7 years after vaccination against pertussis, rubella and mumps after only one vaccination should be considered when recommending new vaccination schedules.

    A pooled analysis was conducted of 1257 toddlers who received a fourth dose of Haemophilus influenzae type b-Neisseria meningitidis serogroups C and Y-tetanus toxoid conjugate vaccine (HibMenCY-TT) or Hib conjugate vaccine (Hib polysaccharide conjugated to N. meningitidis outer membrane protein) coadministered with measles-mumps-rubella (MMR) and varicella (VAR) vaccines (NCT00134719/NCT00289783). Noninferiority of immunological responses to MMR and VAR was demonstrated between groups and incidences of MMR- and VAR-specific solicited symptoms were similar, indicating that HibMenCY-TT can be coadministered with MMR and VAR.

    Rubella is a mild viral disease that typically occurs in childhood. Rubella infection during pregnancy causes congenital rubella syndrome, including the classic triad of cataracts, cardiac abnormalities and sensorineural deafness. Highly effective vaccines have been developed since 1969, and vaccination campaigns have been established in many countries. Although there has been progress, the prevention and diagnosis of rubella remain problematic. This article reviews the implications and management of rubella during pregnancy.

    Measles and rubella are infectious diseases and humans are the only reservoir of these infections. Effective vaccines are available with the potential for measles (MV) and rubella (RuV) virus eradication. According to the World Health Organisation guidelines, a national plan was approved in Italy in 2013 to achieve the MV/RuV elimination by 2015, and active MV/RuV integrated surveillance initiated. Towards this purpose, a regional laboratory centre was set up on 1 September 2013 in Lombardy, Northern Italy. This paper aimed at: (1) evaluating measles-mumps-rubella (MMR) vaccine coverage and MV/RuV notified cases retrospectively; and (2) presenting the results of MV/RuV integrated surveillance (laboratory confirmed and viral genetic profiles).   The 95% target for MMR vaccine coverage was achieved in 2001, and coverage increased until 2007 (96.6%), but then a decreasing trend was observed. Since 2000 to 2014, 3026 rubella cases were notified, with nearly 58% of them in the 2002 epidemic. From 2009, less than 45 RuV cases per year were reported. From 2000 to 2014, 5024 measles cases were notified. Since 2008, three large outbreaks (in 2008, 2011, and 2013) were observed. From data obtained during our surveillance activity, there were no rubella cases, and 57.5% (46/80) collected samples were MV-positive by real-time RT-PCR. A fragment of the MV N gene was sequenced from 37 MV-positive samples; D8, D9, and B3 genotypes were detected. Data obtained retrospectively and from active surveillance underline the necessity to achieve and maintain high vaccination coverage and to improve surveillance and the effectiveness of healthcare actions.

    Uptake rates for the combined measles, mumps and rubella (MMR) vaccine have been below the required 95% in the UK since a retracted and discredited article linking the MMR vaccine with autism and inflammatory bowel disease was released in 1998. This study undertook semi-structured telephone interviews among parents or carers of 47 unvaccinated measles cases who were aged between 13 months and 9 years, during a large measles outbreak in Merseyside. Results showed that concerns over the specific links with autism remain an important cause of refusal to vaccinate, with over half of respondents stating this as a reason. A quarter stated child illness during scheduled vaccination time, while other reasons included general safety concerns and access issues. Over half of respondents felt that more information or a discussion with a health professional would help the decision-making process, while a third stated improved access. There was clear support for vaccination among respondents when asked about current opinions regarding MMR vaccine. The findings support the hypothesis that safety concerns remain a major barrier to MMR vaccination, and also support previous evidence that experience of measles is an important determinant in the decision to vaccinate.

    Molecular data on rubella viruses are limited in Uganda despite the importance of congenital rubella syndrome (CRS). Routine rubella vaccination, while not administered currently in Uganda, is expected to begin by 2015. The World Health Organization recommends that countries without rubella vaccination programs assess the burden of rubella and CRS before starting a routine vaccination program. Uganda is already involved in integrated case-based surveillance, including laboratory testing to confirm measles and rubella, but molecular epidemiologic aspects of rubella circulation have so far not been documented in Uganda. Twenty throat swab or oral fluid samples collected from 12 districts during routine rash and fever surveillance between 2003 and 2012 were identified as rubella virus RNA positive and PCR products encompassing the region used for genotyping were sequenced. Phylogenetic analysis of the 20 sequences identified 19 genotype 1G viruses and 1 genotype 1E virus. Genotype-specific trees showed that the Uganda viruses belonged to specific clusters for both genotypes 1G and 1E and grouped with similar sequences from neighboring countries. Genotype 1G was predominant in Uganda. More epidemiological and molecular epidemiological data are required to determine if genotype 1E is also endemic in Uganda. The information obtained in this study will assist the immunization program in monitoring changes in circulating genotypes.

    Vaccination against measles, mumps, rubella and varicella (MMRV) is currently recommended in developed countries for infants from 12 months of age. However, measles vaccination at 9 months of age is recommended by the WHO in the Expanded Program on Immunization (EPI) schedule and it is therefore possible that MMR or MMRV vaccines might also be given at this age. This open-label, randomised, comparative study evaluated the immunogenicity and safety of a 2-dose schedule of ProQuad(®) (MMRV vaccine) given at a 3-month interval in healthy infants aged ≥9 months. For measles, the non-inferiority of the response rate post-Dose 2 was reached when Dose 1 was administered at 11 months (98%) compared with 12 months (99%) but was not reached when Dose 1 was administered at 9 months (95%). The response rate to measles post-Dose 1 increased with age, from 73% to 88% and 90% at 9, 11 and 12 months, respectively. For mumps, rubella and varicella, response rates were not different after Dose 1 (>95%) or Dose 2 (>99%) regardless of whether Dose 1 was administered at 9, 11 or 12 months of age. In conclusion, the age of administration of the first of a two-dose regimen of ProQuad may be lowered to 11 months. Dose 1 may be administered at 9 months if early protection is required, but it should be recognised that a second dose is required promptly with a minimum of 3-month interval between doses.

    Full Text Available Although thorough studies on the immune reponse to rubella have been per¬formed, less attention has been given to the cellular mechanism and mediators that shape the process. Specifically, information concerning the nature of cytokine patterns involved in the immune response to Rubella vaccination is not available. This study deals with cytokine production patterns of spleen cells from Balb/c mice following vaccination with the Takahashi strain of Rubella vaccine. Mice were injected intraperitonealy with Rubella virus and PBS and 7. 10 or 14 days later, spleen cells were separated and cultured with varying doses of virus, con A or only the medium. ELISA assays were performed on supernatants for measure¬ment of IL-4. INF-y and IL-5. LTT (Lymphocyte Transformation Test was also performed. The data indicate variation in cytokine patterns during the time peri¬ods after vaccination. On day 7 a type 1 pattern was observed. The LTT response was also indicative of CMI (Cell Mediated Immunity response on the 7lh and 14"' days while a transient suppression on day 10 was observed. These results indicate a time dependent cytokine response with variation ultimately leading to a domi¬nant type 1 (Tl cytokine response.

    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.

    The aim of this study was to investigate the incidence rate of rubella in Republika Srpska in the period between 2006 and 2010. The total number of 1236 cases of rubella was reported during the reporting period with manifold increasing incidence from 0.5 in 2006 to 54.7 in 2010 per 100,000 habitants. In the last two years of observation there was a disease outbreak in Republika Srpska. Inadequate immunization, migration and lack of funds caused a reduction in the overall level of public health and health system which led to a drastic increase in the number of rubella cases.

    The Global Polio Eradication Initiative has built an extensive infrastructure with capabilities and resources that should be transitioned to measles and rubella elimination efforts. Measles continues to be a major cause of child mortality globally, and rubella continues to be the leading infectious cause of birth defects. Measles and rubella eradication is feasible and cost saving. The obvious similarities in strategies between polio elimination and measles and rubella elimination include the use of an extensive surveillance and laboratory network, outbreak preparedness and response, extensive communications and social mobilization networks, and the need for periodic supplementary immunization activities. Polio staff and resources are already connected with those of measles and rubella, and transitioning existing capabilities to measles and rubella elimination efforts allows for optimized use of resources and the best opportunity to incorporate important lessons learned from polio eradication, and polio resources are concentrated in the countries with the highest burden of measles and rubella. Measles and rubella elimination strategies rely heavily on achieving and maintaining high vaccination coverage through the routine immunization activity infrastructure, thus creating synergies with immunization systems approaches, in what is termed a "diagonal approach." © The Author 2017.

    Full Text Available Introduction: Despite on mandatory vaccination against rubella, the amount of pregnant women without immunity to rubella may exceed 20%. These women represent a risk group for the rubella disease.Objectives: The goals of the presented work are to analyze the cases of anti-rubella IgM detection in pregnant women, and to develop an algorithm for management of such patients.Materials and Methods: Screening has been performed by ELISA test systems company Radim (Italy. In total 799 patients were examined for rubella in 2013, 56 of them were pregnant women.Results. Positive IgM antibodies to rubella in 2013 have been identified in 5 cases, including 4 pregnant women. A detailed analysis of medical history, clinical and laboratory data has been done. In none of these cases the diagnosis of rubella has been confirmed.Conclusions. The main criterion for the diagnosis of rubella in pregnant women with rubella markers in the absence of clinical symptoms must be a dynamic examination, including study on IgM- and IgG-antibodies to rubella virus. The study must be conducted in the same laboratory at intervals of 10–14 days. In most cases, determination of IgG-antibodies avidity helps to estimate the time of infection. In complicated cases it is recommended to use PCR and immunoblot.

    Full Text Available OBJECTIVE: Nonimmune pregnant women are at risk of developing congenital rubella syndrome and measles complications. We aimed to identify pregnant women susceptible to rubella or measles in order to determine the need for immunity screening and supplemental immunization in women of childbearing age. METHOD: This seroprevalence survey was conducted by convenience sampling in obstetric hospitals affiliated with Shiraz University of Medical Sciences (southern Iran. Serum IgG levels were measured by ELISA. RESULT: Mean age of the 175 pregnant women was 27.3±5.3 (range 16 to 42 years. The geometric mean concentration of anti-rubella IgG was 14.9 IU/mL (CI 95%,14.1-15.5, and that of anti-measles IgG was 13.8 IU/mL (CI 95%, 13-14.5. One hundred sixty-eight women (96% had a protective serologic level (>11 IU/mL of IgG against rubella, and 143 (81.7% had a protective level against measles. Except for a significant inverse correlation that was showed by univariate analysis between anti-rubella IgG and the women's age (P = 0.01, immunity did not correlate with demographic or obstetric characteristics or medical history. There was no significant correlation between anti-rubella and anti-measles IgG levels (P = 0.25. CONCLUSION: Nearly a decade after Iran's nationwide measles-rubella vaccination campaign for the population aged 5-25 years, most pregnant women up to 34 years of age had humoral immunity against rubella. We recommend rubella immunity screening or catch-up immunization for women older than 35 years who wish to become pregnant, and measles immunity screening and appropriate vaccination for all women of childbearing age.

    Full Text Available BACKGROUND: The rubella vaccine was introduced into the immunization program in 1995 in the Shandong province, China. A series of different rubella vaccination strategies were implemented at different stages of measles control in Shandong province. METHODOLOGY/PRINCIPAL FINDINGS: The average reported incidence rate of rubella cases remained at a low level in Shandong province after 1999. However, rubella epidemics occurred repeatedly in 2001/2002, 2006, and 2008/2009. The age of the onset of rubella cases gradually increased during 1999-2010, which showed that most cases were found among the 10 years old in 1999 and among the 17 years old in 2010. Phylogenetic analysis was performed and a phylogenetic tree was constructed based on the World Health Organization standard sequence window for rubella virus isolates. All rubella viruses isolated in Shandong province were divided into 4 genotypes: 1E, 1F, 2A, and 2B. Genotype 1E viruses accounted for the majority (79% of all these viruses. The similarity of nucleotide and amino acid sequences among genotype 1E viruses was 98.2-100% and 99.1-100%, respectively. All Shandong genotype 1E strains, differed from international genotype 1E strains, belonged to cluster 1 and interdigitated with the viruses from other provinces in mainland China. The effective number of infections indicated by a bayesian skyline plot remained constant from 2001 to 2009. CONCLUSIONS/SIGNIFICANCE: The gradual shift of disease burden to an older age group occurred after a rubella-containing vaccine was introduced into the childhood immunization schedule in 1995 in Shandong province. Four genotypes, including 1E, 1F, 2A, and 2B, were found in Shandong province during 2000-2009. Genotype 1E, rather than genotype 1F, became the predominant genotype circulating in Shandong province from 2001. All Shandong genotype 1E viruses belong to the genotype 1E/cluster 1; they have constantly circulated, and co-evolved and co-circulated, with

    Rubella is a mild viral infection affecting women of reproductive age, and the fetus in early pregnancy, leading to miscarriage, stillbirth and Congenital Rubella Syndrome. The present study aimed to assess serum level of anti-rubella antibodies in women younger than 25 years attending medical centers in Ahvaz city. This descriptive cross-sectional study was conducted on 760 women younger than 25 years attending medical centers in Ahvaz. A sample of 3 mL of venous blood was taken from each woman and ELISA method was used to assess anti-rubella IgG levels. Antibody level more than 11 IU/mL was considered safe. Data was analyzed by SPSS software using Chi-square, ANOVA and Pearson Correlation tests. Of total samples, 683 women (88.9%) had immunity against rubella, 80 (10.4%) no immunity and 5 (0.7%) intermediate levels of antibody. Immunity to rubella increased significantly with aging (P = 0.001) and a significant association was found between age and antibody titer (P = 0.001, r = 0.261). More than 95% of 15 to 25 year-old women (main reproductive age in Iran) are within acceptable immunity range. Level of immunity to rubella in women of reproductive age in this region appears satisfactory.

    We conducted a retrospective study of the use of cidofovir and the measles, mumps, and rubella (MMR) vaccineas adjunctive treatments to lesion debridement in patients with recurrent respiratory papillomatosis (RRP). Our study population was made up of 15 children-7 boys and 8 girls, aged 1 to 16 years at diagnosis (mean: 6.2)-with pathologically confirmed RRP who had been followed for at least 1 year. In addition to demographic data, we compiled information on disease severity, the type of adjunctive treatment administered to each patient, the frequency of debridements, the length of observation, and remission rates. Of the 15 patients, 5 had been treated with cidofovirafter debridement (cidofovir-only group), 6 were treated with MMR vaccine after debridement (MMR-only group), 3 were treated with one and later switched to the other based on parental preference, and 1 received neither treatment, only debridement. The initial mean Derkay disease severity scores were 12.6 for the cidofovir-only group and 11.0 for the MMR-only group (p = 0.61). The cidofovir-only patients underwent an average of 11.8 adjunctive treatments and the MMR-only patients an average of 17.7 (p = 0.33). The average duration of observation was 44.0 months in the cidofovir-only group and 64.7 months in the MMR-only group (p = 0.29). Remission rates were 20% in the cidofovir-only group and 50% in the MMR-only group (p = 0.54). Our study found insufficient evidence of any significant differences between cidofovir and the MMR vaccinein terms of the number and frequency of adjunctive treatments and the rates of remission.

    Since children with chronic diseases represent a primary target for immunization strategies, it is important that their immunization coverage and timeliness of vaccines is optimal. We performed a study to measure immunization coverage and timeliness of vaccines in children with type 1 diabetes, HIV infection, Down syndrome, cystic fibrosis, and neurological diseases. A total of 275 children aged 6 months-18 years were included in the study. Coverage for diphtheria-tetanus-pertussis (DTP), polio (Pol), and hepatitis B (HBV) vaccines approximated 85% at 24 months, while measles-mumps-rubella (MMR) coverage was 62%. Immunization coverage for seasonal influenza was 59%. The analysis of timeliness revealed that there was heterogeneity among children with different chronic diseases. A proportional hazard model showed that children with HIV infection had the longest time to complete three doses of DTP, Pol, and HBV, and those with neurological diseases received the first dose of MMR later than the other categories. Causes of missing or delayed vaccination mostly included a concurrent acute disease. Children with chronic diseases should be strictly monitored for routine and recommended vaccinations, and health care providers and families should be properly informed to avoid false contraindications.

    Rubella virus (RV) is the causative agent of the disease known more popularly as German measles. Rubella is predominantly a childhood disease and is endemic throughout the world. Natural infections of rubella occur only in humans and are generally mild. Complications of rubella infection, most commonly polyarthralgia in adult women, do exist; occasionally more serious sequelae occur. However, the primary public health concern of RV infection is its teratogenicity. RV infection of women during...

    The elimination of measles and rubella by 2015 is an important goal set by the World Health Organization European Region (WHO/Europa). Since 1991, the incidence of measles in WHO/Europa declined owing to routine childhood vaccination and supplementary immunization activities in the region. However, in many countries of Western Europe elimination of measles and rubella remains a challenge, and every year there are outbreaks with partly long-lasting transmission chains and dissemination of the virus internationally. In Germany, outbreaks occur because of the high proportion of susceptible individuals in specific population groups. In 2011, over 1,600 cases were reported (19.7 per 1,000,000 inhabitants, data from the Robert Koch Institute) whereas in 2012 only 167 cases were reported to the Robert Koch Institute (2 per 1,000,000 inhabitants). It is unclear whether the declining trend will continue in the following years due to improved vaccination coverage or whether number of cases will rise again because of the accumulation of susceptible groups. In Germany, there are currently no representative, country-wide data on rubella; however, data from the eastern federal states provide important epidemiological insights. Outbreaks are seldom reported, but statutory notification of rubella and congenital rubella syndrome was implemented in March 2013. As a result, it will be possible to better assess the epidemiology of rubella in Germany, although a considerable underreporting of rubella cases is anticipated.

    2014-07-01

    Elimination of measles and rubella in Europe is a feasible objective, but it requires achieving a maintaining a high prevalence of protected individuals in order to prevent cases and outbreaks from imported cases. The epidemiology of measles and rubella in Europe in the period 2003-2013 suggests that we are far away from the elimination target for measles, while the situation is better for rubella. In this situation, a new preventive strategy based on serological surveillance systems should be developed in Europe in order to identify and immunise individuals in population groups without sufficient herd immunity against measles and rubella.

    National and global health policymakers require good information about the costs and benefits of their investments in measles and rubella immunization programs. Building on our review of the existing measles and rubella health economics literature, we develop inputs for use in regional and global models of the expected future benefits and costs of vaccination, treatment, surveillance, and other global coordination activities. Given diversity in the world and limited data, we characterize the costs for countries according to the 2013 World Bank income levels using 2013 U.S. dollars (2013$US). We estimate that routine immunization and supplemental immunization activities will cost governments and donors over 2013$US 2.3 billion per year for the foreseeable future, with high-income countries accounting for 55% of the costs, to vaccinate global birth cohorts of approximately 134 million surviving infants and to protect the global population of over 7 billion people. We find significantly higher costs and health consequences of measles or rubella disease than with vaccine use, with the expected disability-adjusted life year (DALY) loss for case of disease generally at least 100 times the loss per vaccine dose. To support estimates of the economic benefits of investments in measles and/or rubella elimination or control, we characterize the probabilities of various sequelae of measles and rubella infections and vaccine adverse events, the DALY inputs for health outcomes, and the associated treatment costs. Managing measles and rubella to achieve the existing and future regional measles and rubella goals and the objectives of the Global Vaccine Action Plan will require an ongoing commitment of financial resources that will prevent adverse health outcomes and save the associated treatment costs.

    Epidemiological studies of rubella and congenital rubella syndrome (CRS) in Japan have been conducted since the first nationwide rubella epidemic of 1965-1969 and subsequent epidemics of 1975-1977, 1982, 1987-1988, and 1992-1993. Rubella was non-endemic in Japan before the 1975-1977 epidemic, and endemic thereafter. Japan started a selective rubella vaccination program for junior high school girls in 1977, and universal rubella vaccination of children of both sexes in 1989. No nationwide rubella epidemics have occurred since 1994. Only three children with CRS were reported in Japan before 1964; however, many children with CRS were identified in 1965 when a rubella epidemic struck Okinawa, which has many the United States military bases. After the 1965-1969 and 1975-1977 rubella epidemics on the Japanese mainland, small numbers of children with CRS were identified (hospital survey). These findings led to the hypothesis that, compared to U.S. rubella virus strains, Japanese strains of rubella virus are less teratogenic. This hypothesis strongly affected the development of rubella vaccines in Japan. However, retrospective seroepidemiological studies attributed the CRS in many children in Okinawa to the high rate of rubella infection in pregnant women. According to the survey conducted at special schools for the deaf, 83, 232, 77, and 167 children were born with CRS on the Japanese mainland respectively after the 1965-1969, 1975-1977, 1982, and 1987-1988 nationwide rubella epidemics, suggesting that the incidence of CRS in Japan is in fact comparable to that in the U.S. and Europe. Rubella epidemics in children have been effectively prevented since 1994. However, a rubella outbreak among adult males and CRS occurred between 2012 and 2014.

    Enzyme-linked immunosorbent assays for IgM antirubella were carried out on 1,546 sera, using an IgM capture method with a F (ab')2 conjugate (ACCA). Under the conditions described, sera containing IgM antirubella bound up to 15 times as much enzyme activity as negative specimens. Paired serum specimens from 27 patients, serial serum specimens from 6 patients, and single serum specimens from 15 patients who had had recent rubella were examined by the haemagglutination inhibition test (HAI) in the presence and absence of 2-mercaptoethanol following sucrose density gradient centrifugation (SDGC). ACCA confirmed all the results found with HAI following SDGC. Specimens were examined from ten patients with congenital rubella; ACCA confirmed the results found with both immunofluorescence following SDGC and radioimmunoassay. Pre- and post-vaccination specimens from 123 patients who had been vaccinated against rubella were examined. An IgM response could only be demonstrated in the 57 cases when IgG was absent in the first specimen. The specificity of the assay was confirmed by testing 31 serum specimens from rubella immune patients that also contained rheumatoid factor, 163 serum specimens from patients with acute infections other than rubella, and 12 serum specimens from infants with miscellaneous neonatal abnormalities other than congenital rubella. The ACCA proved a simple, sensitive, and specific test for IgM antirubella and the results compared favourably with those obtained by the SDGC technique.

    Like some other countries in the Region, Spain has recently experienced multiple but small measles outbreaks resulting from several importations and in which health care professionals were also infected. The European Regional Verification Commission (RVC) for Measles and Rubella Elimination, an independent panel of experts, conducted an annual review of the reports submitted by the National Verification Committees (NVC) and a country visit to assess the status of interruption of endemic transmission of these diseases in Spain. Essential criteria supporting interruption included absence of endemic transmission in the presence of high-quality surveillance system and genotyping evidence. High vaccination coverage with the first dose of measles -and rubella-containing vaccine (MRCV1) has been maintained above 95% at national level. The figure is based on the number of doses administered to children aged 12-24 months. However, there are two autonomous regions, namely Cataluña and Castilla y Leon with low (rubella-containing vaccine was below 90. On the basis of the evidence provided, with only two imported cases of rubella in 2013, the RVC concluded that endemic transmission of rubella had been interrupted in Spain, but there is a risk of re-establishing transmission due to the sub-optimal population immunity in at least four regions as the coverage with two doses of measles- and rubella- containing vaccines was below the required minimum of 95%.

    Measles and rubella persist in the World Health Organization European Region despite long-standing and widespread use of vaccines against them. Our aim was to review the epidemiology of measles and rubella in relation to the goal of eliminating these diseases from the Region by 2015. We report on the number of measles and rubella cases by country in 2012 and present an analysis of preliminary measles and rubella surveillance data for 2013. We analysed data of these diseases for 2013 by age group, diagnosis confirmation (clinical, laboratory-confirmed and epidemiologically linked), and vaccination, hospitalization and importation status. We also report on measles-related deaths. For 2012, there were 26,785 [corrected] measles cases and 29,601 rubella cases reported in the Region. For 2013, these figures were 31,520 and 39,367 respectively. Most measles cases in 2013 (96%; n = 30,178) were reported by nine countries: Georgia (7830), Germany (1773), Italy (2216), the Netherlands (2499), Romania (1074), the Russian Federation (2174), Turkey (7404), Ukraine (3308) and the United Kingdom (1900). In 2013, most measles cases were among unvaccinated persons and over one in three patients were aged 20 years and older. For 2013, almost all rubella cases were reported by Poland (n = 38,585; 98%). High population immunity and high-quality surveillance are the cornerstones to eliminate measles and rubella. Without sustained political commitment and accelerated action by Member States and partners, the elimination of measles and rubella in the WHO European Region may not be achieved.

    Infections caused by cytomegalovirus (CMV), parvovirus B19 (B19), and rubella can lead to serious complications in pregnant women. The aim of this study was to determine the susceptibility to CMV, B19, and rubella antibodies in pregnant women in Norway. Consecutive sera samples were collected from pregnant women in two different regions in Norway. Sera were collected from age groups; ≤19, 20-24, 25-29, 30-34, 35-39, and ≥40 years old. Of the 2,000 pregnant women tested, anti-CMV IgG was positive in 62.8% anti-parvovirus B19 IgG in 59.7% and anti-rubella IgG in 94.4%. CMV IgG susceptibility has decreased in pregnant women less than 30 years of age, from 60% in a study conducted in 1973-1974 to 37.2% in present study. There was a significant difference in CMV IgG seropositivity rate between the two regions (58.6% and 67.1%). Serum levels of rubella IgG was lowest in age group 25-29 years with a positivity rate of 91.0%. Women born before vaccination with two doses of MMR started, had both a higher positivity rate and significantly higher levels of rubella antibody titre, 96.1% and 82.2 IU/ml compared to those born after 92.9% and 41.7 IU/ml. Significantly lower anti-rubella IgG titre found in the youngest age groups highlights the need for continued antenatal screening. A considerable increase in anti-CMV-IgG seropositivity rate was observed and might be associated with higher rate of breastfeeding and a higher percentage attending day-care centres.

    Measles and congenital rubella syndrome remain significant causes of morbidity and mortality despite available vaccines. HIV-infected youth may be at increased risk of measles because of greater waning immunity after vaccination. At a population level, they constitute a potentially large pool of susceptibles to measles and rubella. More data among HIV-infected youth in sub-Saharan Africa are needed to guide vaccination policy and control strategies. This cross-sectional study was nested within 2 ongoing studies of malaria and HIV in Zambia. Dried blood spot cards from youth (5-15 years) in these studies from 2009 to 2013 were tested for IgG antibodies to measles and rubella viruses. HIV-uninfected youth, HIV-infected treatment-naive youth and HIV-infected youth receiving antiretroviral therapy (ART) were compared. A total of 617 HIV-uninfected, 144 HIV-infected treatment-naive and 128 HIV-infected youth receiving ART were included in this study. The proportion seropositive for measles virus was significantly higher among HIV-uninfected youth (92.5%) compared with HIV-infected treatment-naive youth (74.1%) and HIV-infected youth receiving ART (71.9%). No differences by age were observed. The proportion seropositive for rubella virus was significantly higher among HIV-uninfected youth (54.7%) compared with HIV-infected treatment-naive youth (41.7%) and HIV-infected youth receiving ART (49.6%), with increases observed by age for all groups. Measles seroprevalence was lower among HIV-infected than uninfected youth, consistent with waning immunity after measles vaccination. HIV-infected youth would benefit from revaccination. Half of all youth in rural Zambia were susceptible to rubella and may need targeting for catch-up rubella campaigns when measles-rubella vaccine is introduced.

    Graphs have been used in attempts to show a relationship between the measles, mumps and rubella virus (MMR) vaccine and autism. We examine the topic of graphical representation of data in general, and one of these graphs in particular: the one that appeared in a 1999 letter to The Lancet. That graph combined data from England and from California, USA. The author alleged that this graph illustrated a rise in autism rates linked to the use of the MMR vaccine. By examining the presentation closely, we are able to show how this graph misrepresented the data used. We give advice for both authors and publishers in the use of such graphical treatments of data.

    Involvement of the central nervous system is common in measles, but rare in rubella. However, rubella virus (RV) can cause a variety of central nervous system syndromes, including meningitis, encephalitis, Guillain-Barré syndrome and sub acute sclerosing panencephalitis. We report the occurrence of one fatal case of the encephalitis associated with measles-rubella (MR) vaccine during an immunization campaign in São Paulo, Brazil. A 31 year-old-man, previously in good health, was admitted at emergency room, with confusion, agitation, inability to stand and hold his head up. Ten days prior to admission, he was vaccinated with combined MR vaccine (Serum Institute of India) and three days later he developed 'flu-like' illness with fever, myalgia and headache. Results of clinical and laboratory exams were consistent with a pattern of viral encephalitis. During hospitalization, his condition deteriorated rapidly with tetraplegia and progression to coma. On the 3rd day of hospitalization he died. Histopathology confirmed encephalitis and immunohistochemistry was positive for RV on brain tissue. RV was also detected by qPCR and virus isolation in cerebrospinal fluid, brain and other clinical samples. The sequence obtained from the isolated virus was identical to that of the RA 27/3 vaccine strain.

    Supported by GAVI Alliance, measles-rubella vaccination was introduced in Vietnam in 2014, involving a mass campaign among 1-14 year olds and routine immunization of children aged 9 months. We explore the impact on the incidence of Congenital Rubella Syndrome (CRS) during 2013-2050 of this strategy and variants involving women aged 15-35 years. We use an age and sex-structured dynamic transmission model, set up using recently-collected seroprevalence data from Central Vietnam, and also consider different levels of transmission and contact patterns. If the serological profile resembles that in Central Vietnam, the planned vaccination strategy could potentially prevent 125,000 CRS cases by 2050 in Vietnam, despite outbreaks predicted in the meantime. Targeting the initial campaign at 15-35 year old women with or without children aged 9 months-14 years led to sustained reductions in incidence, unless levels of ongoing transmission were medium-high before vaccination started. Assumptions about contact greatly influenced predictions if the initial campaign just targeted 15-35 year old women and/or levels of ongoing transmission were medium-high. Given increased interest in rubella vaccination, resulting from GAVI Alliance funding, the findings are relevant for many countries.

    A modified rubella virus plaque neutralization test for measuring rubella antibody was developed based on the potentiation of the virus-antibody complex by heterologous anti-immunoglobulin. The test is highly sensitive, yielding titers on the average 50 to 100 times higher than the haemagglutination inhibition test or the conventional plaque neutralization test. The sensitivity of this enhanced neutralization test is somewhat limited by the existence of a prozone phenomenon which precludes testing of low-titered sera below a dilution of 1:16. No prozone effect was observed with cerebrospinal fluids. The specificity of the enhanced neutralization test was determined by seroconversion of individuals receiving rubella vaccine. Although the rubella hemagglutination inhibition test remains the test of choice in routine diagnostic and surveillance work, the enhanced rubella neutralization test is particularly useful in monitoring low-level antibody in the cerebrospinal fluid in patients with neurological disorders and in certain instances of vaccine failure.

    An hypothesis published in 1998 suggested that measles-mumps-rubella vaccine may cause autism as a result of persistent measles virus infection of the gastrointestinal tract. Results of early studies were not supportive and in 2001 a review by the Institute of Medicine concluded that the evidence favors the rejection of a causal relationship at the population level between measles-mumps-rubella vaccine and autistic spectrum disorder. Studies published since the Institute of Medicine report have continued not to find an increased risk of autistic spectrum disorder associated with measles-mumps-rubella. The vaccine also has not been found to be associated with a unique syndrome of developmental regression and gastrointestinal disorders. The evidence now is convincing that the measles-mumps-rubella vaccine does not cause autism or any particular subtypes of autistic spectrum disorder.

    Rubella IgG testing is routinely done in prenatal care and seroepidemiological studies. Recently concern was raised that seropositivity rates were decreasing questioning vaccination policies. Manufacturers of rubella IgG assays and authors of seroepidemiological studies use different cut-offs for the definition of seropositivity. As rubella virus circulation is reduced since many years, seronegativity rates might be overestimated using an inappropriate cut-off. Using different cut-off definitions we compared fourteen current rubella IgG immunoassays for sensitivity and qualitative result concordance in samples with low positive or negative haemagglutination inhibition (HI) titre. 150 clinical samples from patients and health care workers were included in the study. All samples were measured in 14 different rubella IgG immunoassays. Seropositivity was defined using recombinant rubella IgG immunoblot as reference standard. The concordance of qualitative results using the manufacturers cut-off definitions was 56.4% if grey-zone results were analysed separately and 69.8% if grey-zone results were defined as positive. Using universal cut-offs of 10 IU/ml or 15 IU/ml the concordance was 70% and 61.4% respectively. Using the different cut-off definitions up to 71 out of the 124 immunoblot-positive samples tested negative in the immunoassays. The mean coefficient of variation (CV) of quantitative results in positive samples was 51% (range 19-113%). Determination of rubella immunity by measurement of rubella-IgG in a population with high vaccination coverage with current assays leads to a high number of false negative results. The value of routine rubella antibody testing in countries with high vaccination coverage should be discussed. Copyright © 2015 Elsevier B.V. All rights reserved.

    Background. As part of regional elimination efforts, rubella-containing vaccines (RCV) have recently been introduced in the Philippines, yet the true burden of rubella and congenital rubella syndrome (CRS) in the country is largely unknown. Objective. To provide baseline information on rubella and CRS prior to routine vaccine introduction in the Philippines. Methods. We conducted a systematic literature review on rubella and CRS in the Philippines, including a cross-sectional study conducted in 2002 among 383 pregnant women attending the obstetric outpatient clinic of the Philippine General Hospital to assess rubella susceptibility of women of childbearing age. Results. 15 locally published and unpublished studies were reviewed. Susceptibility to rubella among women of childbearing age was higher in rural communities. Retrospective reviews revealed congenital heart diseases, cataracts, and hearing impairments to be most common presentations in children of CRS. In the cross-sectional study, 59 (15.4%) of the 383 pregnant women enrolled were seronegative for rubella IgG. Conclusion. Similar to other countries introducing RCV, it was only recently that surveillance for rubella has been established. Previous studies show substantial disabilities due to CRS and a substantial proportion of susceptible women who are at risk for having babies affected with CRS. Establishment of CRS surveillance and enhanced awareness on rubella case detection should be prioritized. PMID:28115948

    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.

  15. Dilemmas of a vitalizing vaccine market: lessons from the MMR vaccine/autism debate.

    A number of issues related to vaccines and vaccinations in society are discussed in this paper. Our purpose is to merge an analysis of some recent changes in the vaccine market with social science research on the relationship between citizens and authorities. The article has two empirical parts. The first shows how the vaccine market, which for many years has had immense financial problems, nowadays seems to becoming economically vitalized, mostly due to the production of new and profitable vaccines. However prosperous the future may appear, certain reactions from the public regarding vaccination initiatives offer insight into inherent problems of vaccine policies in many Western countries. In the second part of the article, these problems are exemplified with the recent controversy over the MMR (measles, mumps, and rubella) vaccine. We conclude that in spite of the improving profit-margins, the vaccine market remains vulnerable and insecure. Vaccines are permeated by society, even more so than pharmaceutics that are used to cure or alleviate illnesses. Radical changes in financial conditions with promises of a more profitable market will not, we argue, solve other even more fundamental problems.

    Deficient mismatch repair (MMR) is identified as a mutation of one of four major MMR genes and(or) microsatellite instability. These genomic changes are used as markers of MMR status of the heredity nonpolyposis colorectal cancer (HNPCC) spectrum tumors--familial and sporadic tumors of colon and extracolonic cancers fulfilling Amsterdam clinical criteria II. MMR-deficiency results in mutator phenotype and resistance to geno- and cytotoxicity of alkylating agents. The main cytotoxic damage to DNA in response to chemical methylation is O6-methylguanine (O6-mG). The secondary DNA strand breaks, which are formed during the MMR functioning, are proposed to be required for methylation induced cytotoxicity. We have assumed that the secondary double stand breaks (DSB) upon DNA methylation are able to represent functional efficiency of MMR in cells. The purpose of the paper was to test this assumption on human tumor cells differing in MMR-status and pulse-treated with methylnitrosourea (MNU). We used 3 cell lines: HeLa (MMR-competent endometrial tumor cells), HCT116 (MMR-deficient colorectal carcinoma cells), and Colo320 (sigmoid intestine tumor cells with uncharacterized MMR status). DSBs were evaluated with neutral comet assay. Cytotoxicity/viability was evaluated with MTT-asay and apoptotic index (frequency of morphologically determined apoptotic cells). We show that 1) cytotoxic effect of MNU (250 microM) on HeLa cells was exhibited 3 days after pulse-treatment of cells with MNU; 2) DSBs occurred 48 h after the drug treatment but prior to the onset of apoptosis of HeLa cells; 3) MMR-deficient HCT116 cells were resistant to the drug: no decreased viability, DSBs and apoptosis were observed during 3 days after cell treatment. Both cell lines exhibited high sensitivity to etoposide, classical inductor of unrepairable DSBs and p53. Etoposide has been found to induce DSBs in 6-12 h, which was followed by apoptosis (in 24 h). Colo320 cells exhibited intermediate position

    We report a prospective study of 56 pregnant women inadvertently vaccinated with rubella vaccine during the 2006 campaign performed in Argentina. Of these patients, 48 (87%) were immune, whereas the remaining 9 (16%) were susceptible. In the latter group, 7 presented with a primary reaction to the vaccine confirmed through immunoglobulin (Ig) G antibody avidity testing or seroconversion of IgG titers. During the clinical and laboratory follow-up, newborns did not present evidence of infection or malformations compatible with congenital rubella syndrome.

    2016-01-01

    Introduction: The greatest burden for a subset of pathogens is associated with infection during pregnancy. Evidence for teratogenic effects of Zika Virus have highlighted the importance of understanding the epidemiology of such pathogens. Rubella is perhaps the most classic example, and there is much to be learned from the long history of modelling associated with this virus. Methods: We extended an existing framework for modeling age-specific dynamics of rubella to illustrate how the body of knowledge of rubella dynamics informs the dynamics of teratogenic infections more broadly, and particularly the impact of control on such infections in different transmission settings. Results: During invasion, the burden in women of childbearing age is expected to peak, but then fall to low levels before eventually levelling out. Importantly, as illustrated by rubella dynamics, there is potential for a paradoxical effect, where inadequate control efforts can increase the burden. Conclusions: Drawing on the existing body of work on rubella dynamics highlights key knowledge gaps for understanding the risks associated with Zika Virus. The magnitude and impacts of sterilizing immunity, plus antigenic maps measuring cross-protection with other flaviviruses, and the magnitude of transmission, as well as likely impact of control efforts on transmission are likely to be key variables for robust inference into the outcome of management efforts for Zika Virus.

    The long-standing and widespread use of vaccines against measles has resulted in a dramatic decline in cases and measles mortality worldwide compared with the pre-vaccination era.All regions of the World Health Organization (WHO) have measles elimination goals and the WHO regions of the Americas, Europe and Western Pacific also have rubella elimination goals. This article aims to report on progress toward elimination of measles and rubella in the WHO European Region based on the latest available data. We also discuss current challenges and actions needed to reach this goal in the Region. Despite substantial progress made towards controlling measles and rubella, the countries of the WHO European Region continue to face challenges in interrupting endemic transmission of these diseases. Widespread outbreaks and endemic transmission of measles and rubella persisted in some countries of the Region in 2014 and have continued in 2015. Interrupting endemic transmission in each and every country is necessary to declare elimination for the entire Region. High population immunity and high-quality surveillance are the cornerstones to eliminate measles and rubella. In the absence of sustained political commitment and implementation of the required strategies by all countries, the goal of eliminating these diseases in the WHO European Region is at stake.

    Childhood rubella infection in early pregnancy can lead to fetal death or congenital rubella syndrome (CRS) with multiple disabilities. Reduction of transmission via universal vaccination can prevent CRS, but inadequate coverage may increase CRS numbers by increasing the average age at infection. Consequently, many countries do not vaccinate against rubella. The World Health Organization recommends that for safe rubella vaccination, at least 80% coverage of each birth cohort should be sustained. The nonlinear relationship between CRS burden and infection dynamics has been much studied; however, how the complex interaction between epidemic and demographic dynamics affects minimum safe levels of coverage has not been quantitatively evaluated across scales necessary for a global assessment. We modelled 30-year CRS burdens across epidemiological and demographic settings, including the effect of local interruption of transmission via stochastic fadeout. Necessary minimum vaccination coverage increases markedly with birth and transmission rates, independent of amplitude of seasonal fluctuations in transmission. Susceptible build-up in older age groups following local stochastic extinction of rubella increased CRS burden, indicating that spatial context is important. In low birth-rate settings, 80% routine coverage is a conservative guideline, particularly if supplemented with campaigns and vaccination of women of childbearing age. Where birth and transmission rates are high, immunization coverage must be well above 80% and campaigns may be needed. Policy-makers should be aware of the potential negative effect of local extinction of rubella, since heterogeneity in vaccination coverage will shape extinction patterns, potentially increasing CRS burdens.

    Disposable-syringe jet injectors (DSJIs) with single-use, auto disable, needle-free syringes offer the opportunity to avoid hazards associated with injection using a needle and syringe. 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.

    Rubella is a mild disease characterized by low-grade fever, and a morbilliform rash, but causes congenital defects in neonates born from mothers who suffered from rubella during the pregnancy. After many passages of wild-type rubella virus strains in various types of cultured cells, five live attenuated rubella vaccines were developed in Japan. An inability to elicit anti-rubella virus antibodies in experimentally infected animals was used as an in vivo marker phenotype of Japanese rubella vaccines. All Japanese rubella vaccine viruses exhibit a temperature-sensitive (ts) phenotype, and replicate very poorly at a high temperature. We determined the entire genome sequences of three Japanese rubella vaccines (Matsuba, TCRB19, and Matsuura), thereby completing the sequencing of all five Japanese rubella vaccines. In addition, the entire genome sequences of three vaccine progenitors were determined. Comparative nucleotide sequence analyses revealed mutations that were introduced into the genomes of the TO-336 and Matsuura vaccines during their production by laboratory passaging. Analyses involving cellular expression of viral P150 nonstructural protein-derived peptides revealed that the N1159S mutation conferred the ts phenotype on the TO-336 vaccine, and that reduced thermal stability of the P150 protease domain was a cause of the ts phenotype of some rubella vaccine viruses. The ts phenotype of vaccine viruses was not necessarily correlated with their inability to elicit humoral immune responses in animals. Therefore, the molecular mechanisms underlying the inability of these vaccines to elicit humoral responses in animals are more complicated than the previously considered mechanism involving the ts phenotype as the major cause.

    Purpose To determine the prevalence of positive test for Ureaplasma urealyticum (UU), Mycoplasma hominis (MH), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) infections, and their corresponding Rubella status when undergoing workup for infertility. Methods Retrospective chart review to determine infection status for UU, MH, CT, and NG as determined by cervical swab, as well as the serum Rubella antibody titer. Results A total of 46 patients of the patients reviewed were positive for UU (20.1%), three patients were positive for MH (1.3%), five patients were positive for CT (2.2%) and one patient was positive for NG (0.4%). Rubella immunity was confirmed in 90.3% of patients. Conclusion Approximately one quarter of women presenting to an infertility clinic seeking to conceive were found to have a positive test for UU, MH, CT or NG infection. Additionally, almost 10% of the patients were Rubella non-immune at the time of presentation for infertility evaluation. PMID:18202910

    OBJECTIVE:To observe the safety and immunological effects of Measles-mumps-rubella(MMR)attenuated live at-tenuated vaccine in children. METHODS:300 children aged 8-12 months receiving inoculation were selected from Changsha Hospi-tal for Maternal and Child Health Care during Jan. 2015-Apr. 2016 to observe safety and immunological effects. Those children were divided into MMR group,measles vaccine group,mumps vaccine group and rubella vaccine group according to vaccine type, with 75 cases in each group. The occurrence of ADR in 72 h were compared among 4 groups after inoculation;venous blood of chil-dren was collected before vaccination and 5 months after vaccination,and the antibody positive test was carried out by micro coagu-lation inhibition (HI) test;HI antibody titer was recorded after immunization,and positive rate and genometric meantiter(GMT) were calculated. RESULTS:The incidence of ADR in 4 groups were 9.33%,8.00%,8.00% and 10.67%,respectively. No local ADR was found in 4 groups;among systemic ADR,the incidence of fever was higher than that of other clinical manifestations,be-ing 4.00%,4.00%,4.00% and 5.33%;there was no statistical significance in the incidence of ADR among 4 groups(P>0.05). Measles,mumps and rubella antibody positive rates of MMR group were 100%,92.00% and 100%,respectively;antibody posi-tive rates of measles vaccine group,mumps vaccine group and rubella vaccine group were 100%,85.33% and 100%,respective-ly;there was no statistical significance in same antibody positive rate among 4 groups(P>0.05).

    Background Most cases of rubella and congenital rubella syndrome (CRS) occur in low- and middle-income countries. The World Health Organization (WHO) has recently recommended that countries accelerate the uptake of rubella vaccination and the GAVI Alliance is now supporting large scale measles-rubella vaccination campaigns. We performed a review of health economic evaluations of rubella and CRS to identify gaps in the evidence base and suggest possible areas of future research to support the planned global expansion of rubella vaccination and efforts towards potential rubella elimination and eradication. Methods We performed a systematic search of on-line databases and identified articles published between 1970 and 2012 on costs of rubella and CRS treatment and the costs, cost-effectiveness or cost-benefit of rubella vaccination. We reviewed the studies and categorized them by the income level of the countries in which they were performed, study design, and research question answered. We analyzed their methodology, data sources, and other details. We used these data to identify gaps in the evidence and to suggest possible future areas of scientific study. Results We identified 27 studies: 11 cost analyses, 11 cost-benefit analyses, 4 cost-effectiveness analyses, and 1 cost-utility analysis. Of these, 20 studies were conducted in high-income countries, 5 in upper-middle income countries and two in lower-middle income countries. We did not find any studies conducted in low-income countries. CRS was estimated to cost (in 2012 US$) between $4,200 and $57,000 per case annually in middle-income countries and up to $140,000 over a lifetime in high-income countries. Rubella vaccination programs, including the vaccination of health workers, children, and women had favorable cost-effectiveness, cost-utility, or cost-benefit ratios in high- and middle-income countries. Conclusions Treatment of CRS is costly and rubella vaccination programs are highly cost-effective. However

    The number of asylum seekers arriving in Germany has increased rapidly since 2014 and cases of vaccine-preventable diseases at reception centres were reported. Asylum seekers 12 years and older arriving in Lower Saxony were serologically screened for antibodies against measles, rubella and varicella between November 2014 and October 2015. We calculated the seroprevalence from the screening data by disease, country of origin and age group and compared them to literature-based herd immunity thresholds in order to identify immunisation gaps. In total, 23,647 specimens were included in our study. Although the vast majority of asylum seekers tested positive for antibodies against measles, rubella and varicella, the seroprevalences were not sufficient to ensure herd immunity. The seroprevalences varied substantially between countries of origin and increased with age. Immunisation of asylum seekers against measles, rubella and varicella is needed and the detailed information on seroprevalences among subgroups of asylum seekers can be used for targeted immunisations at reception centres.

    Recalcitrant warts represent a frustrating challenge for both patients and physicians. Although many destructive and immunotherapeutic modalities are available for the treatment of warts, an ideal, universally effective approach has not been explored to date. Recently, intralesional antigen immunotherapy has shown promising efficacy in the treatment of warts. The aim of the study was to evaluate the efficacy and safety of intralesional measles, mumps, and rubella (MMR) vaccine in the treatment of recalcitrant warts. The study included 70 adult patients with multiple recalcitrant extragenital warts of different sizes and durations, with or without distant warts. They were directly injected, without a pre-sensitization skin test, with 0.3 intralesional MMR vaccine into the largest wart at 2-week intervals until complete clearance or for a maximum of five treatments. Follow-up was made every month for six months to detect any recurrence. Sixty-five patients, 35 men and 30 women, completed the study, and five patients discontinued for various reasons. Complete clearance of the lesions was observed in 41 patients (63%), partial response in 15 patients (23%), and no response in nine patients (14%). Complete response was demonstrated in 74.5% of those presenting with distant warts. Side effects were mild and insignificant in the form of pain during injection, itching, erythema, and edema at the site of injection and flu-like symptoms. Recurrence was detected in two patients only. Intralesional immunotherapy by MMR vaccine is a promising, effective, and safe treatment modality for recalcitrant warts. © 2014 The International Society of Dermatology.

  12. Enhanced expression of HIV and SIV vaccine antigens in the structural gene region of live attenuated rubella viral vectors and their incorporation into virions.

    Despite the urgent need for an HIV vaccine, its development has been hindered by virus variability, weak immunogenicity of conserved epitopes, and limited durability of the immune response. For other viruses, difficulties with immunogenicity were overcome by developing live attenuated vaccine strains. However, there is no reliable method of attenuation for HIV, and an attenuated strain would risk reversion to wild type. We have developed rubella viral vectors, based on the live attenuated vaccine strain RA27/3, which are capable of expressing important HIV and SIV vaccine antigens. The rubella vaccine strain has demonstrated safety, immunogenicity, and long lasting protection in millions of children. Rubella vectors combine the growth and immunogenicity of live rubella vaccine with the antigenicity of HIV or SIV inserts. This is the first report showing that live attenuated rubella vectors can stably express HIV and SIV vaccine antigens at an insertion site located within the structural gene region. Unlike the Not I site described previously, the new site accommodates a broader range of vaccine antigens without interfering with essential viral functions. In addition, antigens expressed at the structural site were controlled by the strong subgenomic promoter, resulting in higher levels and longer duration of antigen expression. The inserts were expressed as part of the structural polyprotein, processed to free antigen, and incorporated into rubella virions. The rubella vaccine strain readily infects rhesus macaques, and these animals will be the model of choice for testing vector growth in vivo and immunogenicity.

    During a 12-month period 170 women received early postpartum rubella vaccination. An injectable “depot” progestogen was given to each of these patients for contraceptive purposes at the same time as the vaccine was administered. Subsequent observations showed that the progestogen was effective as a contraceptive in this context and that it did not appear to affect the immune response of the patients to the vaccine.

    The aim of the study is to evaluate seroprevalence of rubella virus (RV), cytomegalovirus (CMV), varicella zoster virus (VZV), and parvovirus B19 (PB19) in 404 Tunisian pregnant women, and to determine reliability of maternal past history of eruption. Sociodemographic characteristics, risk factors, and past history of eruption were collected through a questionnaire. Serologic tests were performed using enzyme immunoassays. Risk factors were analyzed using univariate and multivariate logistic regression models. Seroprevalences were 79.7% for rubella, 96.3% for CMV, 80.9% for VZV, and 76.2% for PB19. In multivariate analysis, the number of persons per room (> 2) in the house during childhood was associated with CMV infection (P = 0.004), irregular professional husband's activity was correlated with VZV infection (P = 0.04), and an age of more than 30 years was associated with PB19 infection (P = 0.02). History of rubella, varicella, and PB19 infection was unknown for, respectively, 55.8%, 20%, and 100% of women. False history of rubella and varicella were found for 7.4% and 15% of women, respectively. The positive and negative predictive values (PPV and NPV) of rubella history were, respectively, 92.6% and 17.2%, and were, respectively, 84.9% and 20.9% for varicella history. Susceptibility to RV, VZV, and PB19 infection remains high in pregnancy in our population. Preventive strategies against congenital rubella must be reinforced. Vaccination against VZV should be considered in seronegative women. Systemic CMV screening is not warranted in our country where high immunity is acquired probably in childhood. Since maternal history of eruption is not reliable, we recommend serologic testing to determine immune status of women.

    Vaccination campaigns are one of the most important and successful public health programs ever undertaken. People who want to learn about vaccines in order to make an informed decision on whether to vaccinate are faced with a wealth of information on the Internet, both for and against vaccinations. In this paper we develop an automated way to score Internet search queries and web pages as to the likelihood that a person making these queries or reading those pages would decide to vaccinate. We apply this method to data from a major Internet search engine, while people seek information about the Measles, Mumps and Rubella (MMR) vaccine. We show that our method is accurate, and use it to learn about the information acquisition process of people. Our results show that people who are pro-vaccination as well as people who are anti-vaccination seek similar information, but browsing this information has differing effect on their future browsing. These findings demonstrate the need for health authorities to tailor their information according to the current stance of users.

    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. 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. 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. 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.

    Considering the febrile seizure rate, there is no longer a clear preference for use of measles-mumps-rubella-varicella (MMRV) vaccine over separate measles-mumps-rubella (MMR) and varicella (V) vaccine. This work was undertaken to assess the risk of febrile seizure after MMRV vaccine in children. We searched PubMed, Embase, BIOSIS Previews, Scopus, Web of Science, Cochrane Library and other databases through 12 December 2014. Meta-analysis was conducted using R version 3.1.2 and Stata version 12.0. A total of thirty-nine studies were included. Thirty-one published or unpublished clinical trials involving about 40,000 subjects did not show significant differences in incidence of febrile seizure or vaccine related febrile seizure between MMRV and MMR with or without varicella vaccine after any doses, in the risk windows of 0-28, 0-42 or 0-56 days and 7-10 days. In addition, these studies showed that the receipt of concomitant use of MMRV and other pediatric vaccines was not a significant predictor of febrile seizure. Eight post-marketing observations involving more than 3,200,000 subjects were included. No evidence suggested elevated risk of febrile seizure associated with MMRV vaccine among children aged 4-6 years old during 7-10 days or 0-42 days after vaccination. However, an approximately 2-fold increase in risk of seizure or febrile seizure during 7-10 days or 5-12 days after MMRV vaccination was found among children aged 10-24 months, although the highest incidence of seizure was still lower than 2.95‰. First MMRV vaccine dose in children aged 10-24 months was associated with an elevated risk of seizure or febrile seizure. Further post-marketing restudies based on more rigorous study design are needed to confirm the findings. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The current Plan for the elimination of measles and rubella is made of the Plan for the elimination of measles in Spain, set up in 2001, and the Surveillance protocol of rubella and congenital rubella syndrome in the phase of elimination, established in 2007. The monitoring of the elimination of both diseases conducted from the European Region of World Health Organization (WHO) has been reinforced since 2010. An annual report with information on the situation of measles and rubella in The Member Estates is being requested since 2013. The Ministry of Health, Social Services and Equality nominated a National Committee for Verification of Measles and Rubella Elimination in 2013, for the review and delivery of the requested information. The strategies and activities currently recommended from the WHO European Region, the verification process in Spain, and the steps to follow for the updating of the Plan for the elimination of measles and rubella in Spain are mentioned in this article.

    The objective of this project was to document and increase vaccine coverage in migrant school children on the Thailand-Myanmar border. Migrant school children (n = 12,277) were enrolled in a school-based immunization program in four Thai border districts. The children were evaluated for vaccination completion and timing, for six different vaccines: Bacille Calmette-Guerin (BCG); Oral Polio vaccine (OPV); Hepatitis B vaccine (HepB); Diphtheria, Pertussis and Tetanus vaccine (DTP); Measles Containing Vaccine or Measles, Mumps and Rubella vaccine (MMR); Tetanus and Diphtheria containing vaccine (Td). Vaccine coverage proportions for BCG, OPV3, DTP3, HepB3 and measles containing vaccine were 92.3, 85.3, 63.8, 72.2, and 90.9 % respectively. Most children were able to receive vaccines in a time appropriate manner. School-based immunization programs offer a suitable vaccine delivery mechanism for hard-to-reach populations. However, these data suggest overall low vaccine coverage in migrant populations. Further efforts toward improving appropriate vaccine coverage and methods of retaining documentation of vaccination in mobile migrant populations are necessary for improved health.

    We report the first case of an occurrence of multiphasic acute disseminated encephalomyelitis (ADEM) associated with atypical rubella virus infection with no rash and long-term increased titers of serum anti-rubella IgM in a 17-year-old male who had no history of rubella vaccination. He suffered from at least six clinical exacerbations with disseminated hyperintense lesions on FLAIR MR images during the course of 18 months. Repeated methylprednisolone pulse therapy and intravenous immunoglobulin therapy resolved the exacerbations. In patients with multiphasic ADEM of unknown etiology, clinicians should also consider the possibility of preceding infection with rubella virus.

    The currently available treatments for warts, including cryosurgery, laser surgery, electrosurgery, and topical keratolytic applications, are often very painful and can induce disfiguring scars. Recently, intralesional immunotherapy with skin test antigens and vaccines has been shown to be effective in the management of warts. To evaluate the efficacy of a new intralesional immunotherapy for warts, using the measles, mumps and rubella (MMR) vaccine. A retrospective study was performed, and we enrolled 136 patients with various types of warts into the study, which was for a duration of 2 years. Patients were treated for a total of six times at 2-week intervals. The treatment response was classified as one of three levels, based on reduction in the size and number of warts, and patients with complete response (CR) were checked for recurrence. Clinical evaluations were carried out using photographs and medical records. Over half (51.5%) of patients experienced > 50% reduction in the size and number of warts, and 46.7% who had distant warts (in different locations) showed good response. Common warts showed significantly higher treatment response than other types of warts (P warts after 6 months. We suggest that intralesional immunotherapy with MMR vaccine is a tolerable and effective method for patients who are sensitive to pain, concerned about side effects, or have common warts. Treatment response is improved by increasing the number of injections. © 2014 British Association of Dermatologists.

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

    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.

    Concerns about vaccine safety have led some parents to decline recommended vaccination of their children, leading to the resurgence of diseases. Reassurance of vaccine safety remains critical for population health. This study systematically reviewed the literature on the safety of routine vaccines recommended for children in the United States. Data sources included PubMed, Advisory Committee on Immunization Practices statements, package inserts, existing reviews, manufacturer information packets, and the 2011 Institute of Medicine consensus report on vaccine safety. We augmented the Institute of Medicine report with more recent studies and increased the scope to include more vaccines. Only studies that used active surveillance and had a control mechanism were included. Formulations not used in the United States were excluded. Adverse events and patient and vaccine characteristics were abstracted. Adverse event collection and reporting was evaluated by using the McHarm scale. We were unable to pool results. Strength of evidence was rated as high, moderate, low, or insufficient. Of 20 478 titles identified, 67 were included. Strength of evidence was high for measles/mumps/rubella (MMR) vaccine and febrile seizures; the varicella vaccine was associated with complications in immunodeficient individuals. There is strong evidence that MMR vaccine is not associated with autism. There is moderate evidence that rotavirus vaccines are associated with intussusception. Limitations of the study include that the majority of studies did not investigate or identify risk factors for AEs; and the severity of AEs was inconsistently reported. We found evidence that some vaccines are associated with serious AEs; however, these events are extremely rare and must be weighed against the protective benefits that vaccines provide.

    Despite the launch of a WHO European Region strategic plan 2005-2010 for eliminating measles and rubella and preventing congenital rubella (CR) infection, measles and rubella are still circulating in Europe. Increased transmission and outbreaks of measles in Europe were still observed in 2011. In Italy, the objectives of the National Plan (2003-2007) for measles elimination have not yet been achieved. The goal of measles elimination and incidence reduction of CR cases has been postponed to 2015 by the Italian Ministry of Health through the implementation of the new National Plan 2010-2015 which will require (1) the achievement of more than 95% coverage with 1 dose and two doses of measles containing vaccine (MCV), respectively, within 24 mo and within 12 y of age; (2) supplementary vaccination activities aimed at susceptible populations including adolescents, young adults and those at risk (health care and educational workers, military, groups "hard to reach" like nomads); and in addition, (3) reduction to less than 5% in the proportion of susceptible women of childbearing age (especially immigrant women). Experiences at regional level, like in Tuscany, have shown promising results in order to create an integrated surveillance system between regional and local health authorities, university and laboratory and in the future, to validate elimination. Moreover, the evaluation of all preventive activities performed in Tuscany during the last decade, immunization coverage data, sero-epidemiological population profile and incidence of measles and rubella cases has highlighted critical points which should be improved and good practices already implemented which should be maintained in the future in order to reach the new goals.

    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.

  12. Updating Standard Procedures for Diagnosis and Treatment of Congenital Rubella Case

    Full Text Available Congenital Rubella is the dramatic consequence of rubella during gestation. A combined strategy of Measles and Rubella universal vaccination on children and selective vaccination of susceptible women has been shown effective in the elimination of congenital rubella requiring an incidence of <1 case of CRS per 100,000 live births. Verification processes of rubella elimination require that physicians early and appropriately diagnose all cases of congenital rubella, including those unpatent at birth. The paper highlights clinical and laboratory aspects channeling diagnosis of congenital rubella infection or syndrome even after the first year of life, and the short- and long-term management criteria.

    A large rubella outbreak has been observed since June 2012 in Tokyo, Japan, and a rapid increase in the number of congenital rubella syndrome (CRS) cases have also been reported in Japan since October 2012. All the clinically diagnosed and laboratory-confirmed rubella cases reported in Tokyo from January 2012 to December 2013 and all the laboratory-confirmed CRS cases from January 2012 to March 2014 were analyzed. In total, 4,116 rubella cases were reported in Tokyo. Of these, 77.2% (n=3,176) were male; the highest number of cases occurred in males aged 35-39 years and in females aged 20-24 years. Complications included arthralgia/arthritis (19.4%), thrombocytopenic purpura (0.5%), hepatic dysfunction (0.3%), and encephalitis (0.1%). The circulating rubella virus in Tokyo was genotype 2B. The most possible site of transmission was the workplace. Because of the rubella epidemic, 16 CRS cases were reported in Tokyo from March 2013 to February 2014. Domestic infection with rubella was proven for all mothers of 16 cases. This situation suggests that Japan is still working to achieve rubella elimination.

    Eradication of vaccine-preventable diseases is one of the most important goals of public health interventions. Herd immunity can be established by national vaccination programs. However, once the national vaccination program stops for any reason, unprotected group will be generated depending on an unfortunate year of birth. Currently, there are 2 major concerns regarding vaccine cohort gaps in Japan: one is for the rubella vaccine, the other for the human papillomavirus (HPV) vaccine.

    Health care personnel are required to be immune against vaccine-preventable diseases, such as measles, mumps, rubella, and varicella. The aim of this study is to evaluate the accuracy of self-reported histories of disease and vaccination against measles, mumps, rubella, and varicella in order to determine the immune status of health care personnel. A self-reported questionnaire of history of previous disease and vaccination against these diseases was administered to a total of 910 health care personnel in Shimane university hospital in Japan, whose results were compared with serological evidences. There were numerous subjects who did not remember a history of disease (greater than 33% each) and of vaccination (greater than 58% each). Self-reported history of disease and vaccination had high positive predictive value against either disease for testing positive for antiviral antibodies. However, a considerable number of false-negative subjects could be found; 88.9% of subjects for measles, 89.3% for mumps, 62.2% for rubella and 96.3% for varicella in the population who had neither a self-reported history of disease nor a vaccination against each disease. In addition, regardless of the disease in question, a negative predictive value in self-reported history of disease and vaccination was remarkably low. These results suggest that self-reported history of disease and vaccination was not predictive to determine the accurate immune status of health care personnel against measles, mumps, rubella, and varicella. A seroprevalence survey, followed by an adequate immunization program for susceptible subjects, is crucial to prevent and control infection in hospital settings.

  17. Mathematical model of MMR inversion for geophysical data

    2007-09-01

    Full Text Available In this paper, we present an analysis of the solution to a number of geophysical inverse problems which are generally non-unique. The mathematical inverse problem that arises is commonly ill-posed in the sense that small changes in the data lead to large changes in the solution. We conduct the inversion algorithm to explore the conductivity for the ground structure. The algorithm uses the data in the form of magnetic field measurements for magnetometric resistivity (MMR. The inversion example is performed to investigate the conductivity ground profile that best fits the observed data. The result is compared with the true model and discussed to show the efficiency of the method. The model for the inversion example with the apparent conductivity and the true conductivity are plotted to show the convergence of the algorithm.

    Host antiviral genes are important regulators of antiviral immunity and plausible genetic determinants of immune response heterogeneity after vaccination. We genotyped and analyzed 307 common candidate tagSNPs from 12 antiviral genes in a cohort of 745 schoolchildren immunized with two doses of measles-mumps-rubella (MMR) vaccine. Associations between SNPs/haplotypes and measles virus-specific immune outcomes were assessed using linear regression methodologies in Caucasians and African-Americans. Genetic variants within the DDX58/RIG-I gene, including a coding polymorphism (rs3205166/Val800Val), were associated as single-SNPs (p≤0.017; although these SNPs did not remain significant after correction for false discovery rate/FDR) and in haplotype-level analysis, with measles-specific antibody variations in Caucasians (haplotype allele p-value=0.021; haplotype global p-value=0.076). Four DDX58 polymorphisms, in high LD, demonstrated also associations (after correction for FDR) with variations in both measles-specific IFN-γ and IL-2 secretion in Caucasians (p≤0.001, q=0.193). Two intronic OAS1 polymorphisms, including the functional OAS1 SNP rs10774671 (p=0.003), demonstrated evidence of association with a significant allele-dose-related increase in neutralizing antibody levels in African-Americans. Genotype and haplotype-level associations demonstrated the role of ADAR genetic variants, including a non-synonymous SNP (rs2229857/Arg384Lys; p=0.01), in regulating measles virus-specific IFN-γ Elispot responses in Caucasians (haplotype global p-value=0.017). After correction for FDR, 15 single-SNP associations (11 SNPs in Caucasians and 4 SNPs in African-Americans) still remained significant at the q-valuemeasles vaccine in Caucasians and African-Americans.

    Simultaneous PET and MR acquisitions have now become possible with the new hybrid Biograph Molecular MR (mMR) scanner from Siemens. The purpose of this work is to create a platform for mMR 3D and 4D PET image reconstruction which would be freely accessible to the community as well as fully adjustable in order to obtain optimal images for a given research task in PET imaging. The proposed platform is envisaged to prove useful in developing novel and robust image bio-markers which could then be adapted for use on the mMR scanner.

  3. Timely MMR vaccination in infancy: influence of attitudes and medical advice on the willingness to vaccinate.

    2012-11-01

    In light of the failure to eliminate measles by 2010, the closure of any gaps in immunisation coverage is of paramount importance to interrupt transmission and to protect vulnerable individuals. Not only vaccination-critical attitudes of parents but furthermore the medical advice by physician in charge influence the vaccine uptake. 3 groups of factors which potentially influence parental decisions on child vaccination were analysed by univariable and multivariable logistic regression for the timely uptake of the first and the second dose of measles vaccination: parents' attitudes towards immunization, the influence of medical and laypersons and the influence of the advice of a medical doctor. A total of 3 041 children were eligible for the analysis. 53.0% of these received the first and 42.9% the second MMR dose in time. If parents considered that vaccinations are important and protective as well as the consulted physician advices towards vaccinations, children had significantly higher chances of a timely vaccination. Whereas, if parents were afraid of vaccinations or get advised by an alternative practitioner, the children had lower chances of being vaccinated in time. If medical providers help parents to reduce uncertainties about vaccination the chance for children to be vaccinated in time increased. It appeared that there still are unmet information needs after the medical consultation. By and large the medical advice plays an important role for vaccination uptake and its timing. In order to raise the vaccination rates further target-population specific approaches are needed.

  4. Is hospital based MMR vaccination for children with egg allergy here to stay?

    LENUS (Irish Health Repository)

    Hawkes, C P

    2010-01-01

    Egg allergy is incorrectly considered to constitute a contraindication to MMR in the community, despite a long history of its safe administration to egg allergic children. The product insert perpetuates this misinformation but the Irish guidelines from the RCPI are unequivocal. We reviewed all paediatric cases vaccinated in our hospital in 2007-2008. Forty seven of 91 children receiving vaccinations in hospital, had been referred for MMR due to concerns regarding egg allergy. In 32% (n=15), GP referral for vaccination was made despite correspondence from the clinic advising routine vaccination in the community. Nineteen were second MMR immunisations, which should all have occurred in the community. Unnecessary hospital referral for MMR vaccination is an extra burden on hospital resources, and causes unwarranted anxiety amongst parents of children with egg allergy. A change in practice seems difficult to achieve, as many referrals happen despite individualised correspondence to GPs and other referring clinicians outlining the current guidelines.

    Contested reports associating the MMR vaccine with autism have resulted in diminished confidence and uptake of the vaccine in the UK. This postal survey of parent's decisions, attitudes and use of information about MMR immunisation was constructed from questions derived from in-depth qualitative work. The setting was a Primary Care Trust in northeast England (N=996). Both MMR-accepting and refusing parents were supportive of immunisation, yet the high level of concern about the safety of the vaccine expressed even by parents who had immunised their children is worrying in its implications for public confidence and trust in health care. The findings suggest that the ability of practitioners to provide effective professional advice about MMR vaccine could be undermined if a government were to directly promote the vaccine to parents. Practitioners should continue to provide parents with accurate information, while communicating respect for parents' intentions to protect their children's health.

    The MMR vaccination coverage in Malopolskie voivodeship improved rapidly and finally reached a high level during last years. The number of new cases of autism spectrum disorders in children during that time revealed a slightly rising but not significant trend, while the number of childhood autism were stable. Ecological study showed no correlation between MMR vaccination and an increased risk of childhood autism and autism spectrum disorders in children.

    Efflux pumps are membrane proteins capable of actively transporting a broad range of substrates from the cytoplasm to the exterior of the cell. Increased efflux activity in response to drug treatment may be the first step in the development of bacterial drug resistance. Previous studies showed that the efflux pump Mmr was significantly overexpressed in strains exposed to isoniazid. In the work to be described, we constructed mutants lacking or overexpressing Mmr in order to clarify the role of this efflux pump in the development of resistance to isoniazid and other drugs in M. tuberculosis. The mmr knockout mutant showed an increased susceptibility to ethidium bromide, tetraphenylphosphonium, and cetyltrimethylammonium bromide (CTAB). Overexpression of mmr caused a decreased susceptibility to ethidium bromide, acriflavine, and safranin O that was obliterated in the presence of the efflux inhibitors verapamil and carbonyl cyanide m-chlorophenylhydrazone. Isoniazid susceptibility was not affected by the absence or overexpression of mmr. The fluorometric method allowed the detection of a decreased efflux of ethidium bromide in the knockout mutant, whereas the overexpressed strain showed increased efflux of this dye. This increased efflux activity was inhibited in the presence of efflux inhibitors. Under our experimental conditions, we have found that efflux pump Mmr is mainly involved in the susceptibility to quaternary compounds such as ethidium bromide and disinfectants such as CTAB. The contribution of this efflux pump to isoniazid resistance in Mycobacterium tuberculosis still needs to be further elucidated.

    Several studies have reported that, in Lynch syndrome resulting from mutations of the mismatch repair (MMR) genes, a CA repeat ≤17 within the IGF1 promoter, SNPs within the xenobiotic metabolizing enzyme gene CYP1A1 and SNPs on 8q23.3 and 11q23.1 modify colorectal cancer (CRC) risk in MMR mutation carriers. We analysed the impact of these polymorphisms on CRC risk in 748 French MMR mutation carriers derived from 359 families. We also analysed the effect of the Novel 1 SNP (18q21), which has recently been shown to increase CRC risk in the general population. We observed a significant difference in the CRC-free survival time between males and females, between MSH2 and MSH6 mutation carriers and between MLH1 and MSH6, indicating that this series is representative of Lynch syndrome. In contrast, the univariate log-rank test, as well as multivariate Cox model analysis controlling for familial aggregation and mutated MMR gene, year of birth and gender showed that the polymorphic alleles tested were not associated with a significant CRC risk increase, neither on the entire sample nor among males and females. This discrepancy with previous reports might be explained both by the genetic heterogeneity between the different populations analysed and the allelic heterogeneity of the MMR mutations. We conclude that genotyping of these polymorphisms is not useful to evaluate CRC risk in MMR mutation carriers and to optimize their clinical follow-up.

    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.

    Objective:To analyse the laboratory surveillance data from 2004 till 2008 to examine the changing trend of ru-bella cases in Malaysia.Methods:Samples for this study were either received through the measles case based surveillance program or were hospital cases received for sero-diagnosis of congenital rubella syndrome (CRS). Specific rubella IgMantibody test was carried out on all samples that were negative for measles IgM antibody and for sero-diagnosis of CRS.Results:Through the surveillance program for measles,the samples received for rubella had increased five fold from 365 in 2004 to 1 522 in 2007.Positive rubella cases detected had also in-creased from 4.1 % in 2004 to 33.2 % in 2007.The age group 11 to 20 years accounted for 73.6 % of rubel-la cases confirmed in 2008,with a higher incidence among males than females.Positive rubella IgMwas detec-ted in 25 CRS cases during the 6 year period between January 2003 and December 2008.Conclusion:The mea-sles elimination program had contributed to significant progress in the control of rubella,with the majority of rubella cases detected through this strategy.Since rubella is not notifiable in Malaysia,this integrated measles and rubella surveillance should be continued.However,to enhance the progress,specific targets should also be established in the national program to eliminate rubella and CRS.

    1975-01-01

    An attempt was made to develop a test requiring no preadsorption steps for the assessment of antibodies to rubella and mumps viruses using the passive immune agglutination (PIA) method. Both rubella and mumps antigens and antibodies were prepared. Direct PIA tests, using rubella antigen-coated beads, and indirect PIA tests, using rubella antibody-coated beads, were investigated. Attempts, using either method, were unsuccessful. Serum interference along with nonspecific agglutination of beads by the rubella antigen resulted in no specific response under the test conditions investigated. A new, highly sensitive approach, the enzyme immunoassay (EIA) test system, is recommended to overcome the nonspecificity. This system is a logical outgrowth of some of the solid phase work done on MEMS and represents the next generation tests system that can be directly applied to early disease detection and monitoring.

    2014-01-01

    While the systemic disorders associated with measles, mumps, and rubella viruses and human parvovirus B19 tend to be mild, each virus can produce potentially life-threatening neurologic disease in human hosts, especially when these viruses infect young children. Two of the viruses, rubella and parvovirus B19, can be vertically transmitted to fetuses during maternal infection and cause congenital infection. Neurologic complications are common after intrauterine infection with the rubella virus, a condition known as the congenital rubella syndrome. Two, measles and rubella viruses, can induce "slow viral" infections, serious, disorders that can occur several years after the initial exposure to the virus and typically have fatal outcomes.

    Constitutional mismatch repair-deficiency, due to biallelic mutations of MMR genes, results in a tumour spectrum characterized by leukaemias, lymphomas, brain tumours and adenocarcinomas of the gastro-intestinal tract, occurring mostly in childhood. We report here two families illustrating the phenotypic diversity associated with biallelic MMR mutations. In the first family, two siblings developed six malignancies including glioblastoma, lymphoblastic T cell lymphoma, rectal and small bowel adenocarcinoma with onset as early as 6 years of age. We showed that this dramatic clinical presentation was due to the presence of two complex genomic PMS2 deletions in each patient predicted to result into complete PMS2 inactivation. In the second family, the index case presented with an early form of Lynch syndrome with colorectal adenocarcinomas at ages 17 and 20 years, and urinary tract tumours at the age of 25 years. We identified in this patient two MSH6 mutations corresponding to a frameshift deletion and an in frame deletion. The latter was not predicted to result into complete inactivation of MSH6. These reports show that the clinical expression of biallelic MMR mutations depends on the biological impact of the second MMR mutation and that, in clinical practice, the presence of a second MMR mutation located in trans should also be considered in patients suspected to present a Lynch syndrome with an unusual early-onset of tumours.

    As a part of measles outbreak based surveillance undertaken by the World Health Organization India, suspected measles cases were referred for the laboratory diagnosis at National Institute of Virology (NIV) Pune and NIV Unit Bengaluru. Altogether, 4,592 serum samples were referred during 2010-2015 from the States of Karnataka (n = 1,173), Kerala (n = 559), and Maharashtra (n = 2,860). Initially, serum samples were tested in measles IgM antibody EIA and samples with measles negative and equivocal results (n = 1,954) were subjected to rubella IgM antibody detection. Overall, 62.9% (2,889/4,592) samples were laboratory confirmed measles, 27.7% (542/1,954) were laboratory confirmed rubella and remaining 25.2% (1,161/4,592) were negative for measles and rubella. The measles vaccination status was available for 1,206 cases. Among the vaccinated individuals, 50.7% (612/1,206) were laboratory confirmed measles. The contribution of laboratory confirmed measles was 493 (40.8%) from Maharashtra, 90 (7.5%) from Karnataka, and 29 (2.4%) from Kerala. Since, 1/3rd of suspected measles cases were laboratory confirmed rubella, an urgent attention needed to build rubella surveillance in India. Additional efforts are required to rule out other exanthematous disease including Dengue and Chikungunya in measles and rubella negatives. J. Med.

  18. Nitric Oxide-Sensitive Pulmonary Hypertension in Congenital Rubella Syndrome

    2015-01-01

    Full Text Available Persistent pulmonary hypertension is a very rare presentation of congenital virus infection. We discuss the case of complete congenital rubella syndrome presenting at echocardiography with pulmonary hypertension that worsened after ductus ligation. Cardiac catheterization showed a normal pulmonary valve and vascular tree but a PAP=40 mmHg. The infant promptly responded to inhaled nitric oxide while on mechanical ventilation and was later shifted to oral sildenafil. It is not clear whether our observation may be due to direct viral damage to the endothelium or to the rubella virus increasing the vascular tone via a metabolic derangement.

    Although most infections with the rubella virus result in relatively minor sequelae, rubella infection in early pregnancy may lead to severe adverse outcomes for the fetus. First recognized in 1941, congenital rubella syndrome (CRS) can manifest with a diverse range of symptoms, including congenital cataracts, glaucoma, and cardiac defects, as well as hearing and intellectual disability. The gestational age of the fetus at the time of the maternal rubella infection impacts the probability and severity of outcomes, with infection in early pregnancy increasing the risks of spontaneous termination (miscarriage), fetal death (stillbirth), birth defects, and reduced survival for live-born infants. Rubella vaccination continues to change the epidemiology of rubella and CRS globally, but no models currently exist to evaluate the economic benefits of rubella management. This systematic review provides an overall assessment of the weight of the evidence for the outcomes associated with rubella infections in the first 20 weeks of pregnancy. We identified, evaluated, and graded 31 studies (all from developed countries) that reported on the pregnancy outcomes of at least 30 maternal rubella infections. We used the available evidence to estimate the increased risks of spontaneous termination, fetal death, infant death, and CRS as a function of the timing of rubella infection in pregnancy and decisions about induced termination. These data support the characterization of the disability-adjusted life years for outcomes associated with rubella infection in pregnancy. We find significant impacts associated with maternal rubella infections in early pregnancy, which economic analyses will miss if they only focus on live births of CRS cases. Our estimates of fetal loss from increased induced terminations due to maternal rubella infections provide context that may help to explain the relatively low numbers of observed CRS cases per year despite potentially large burdens of disease.

    Rubella is a mild self-limiting contagious viral disease caused by the rubella virus (RV). Although symptoms are often mild, the concern is centralized around the possible effect on a fetus growth and development in case of primary infection during early months of pregnancy. Recently acquired rubella is commonly confirmed by RV-specific IgM antibody detection in the serum. However, rubella primary infection is not always the only cause of IgM positivity. Other possible causes of rubella IgM positivity may include IgM persistence following vaccination or naturally acquired infection or even re-infection. Moreover, nonspecific IgM reactivity can cause false-positive results. There are few articles to differentiate the aetiology of rash in rubella-like illnesses. However, limited studies have been conducted on clarifying the source of IgM positivity in these cases. This article reports the study of 10,896 clinical cases demonstrating rubella-like illness between 2011 and 2013 in Iran. The rate of IgM positivity among these cases was 0.52% (57 cases). As predicted based on the high coverage of vaccination in Iran fewer than 16% of cases with ELISA IgM positive result, were due to current rubella primary infections. The greater part of the positive IgM reactions occurred in cross reactivity with other viruses (31.6%) or in prolonged IgM response post vaccination (24.6%). This research confirmed that the positive result of rubella IgM assay in vaccinated individuals is mainly caused by prolonged IgM production, rubella re-infection, and false positivity due to infection with other viruses, rather than the rubella primary infection itself.

    The National Plan for the Elimination of Rubella was implemented in Spain in 2008 using the logistics of the National Plan for the Elimination of Measles that have been employed since year 2000. Molecular characterization of rubella virus (RUBV) is important for disease surveillance and for monitoring elimination of the disease throughout the world. We describe the first complete series of data regarding the circulation of RUBV genotypes in Spain. The 739-nucleotide fragment designated by the WHO for RUBV genotyping was sequenced in 88 selected cases collected from 1998 to 2014. Five genotypes were identified: 1E, 2B, 1J, 1I, and 1a. Genotype 1E was predominant between 1998 and 2003 but was replaced by genotype 2B, which was detected in sporadic cases in 2004, 2006, 2008, 2012, 2013 and 2014. There was an outbreak of genotype 2B in Algeciras (Andalusia) in 2008. Genotype 1J caused an outbreak in Madrid in 2004/2005 and sporadic cases in 2005 and 2007. Genotype 1I was found to have infected an immune-suppressed patient with neurological symptoms in 2008. Finally, vaccine strain RA 27/3 was detected in three sporadic cases, two of them immune-suppressed and without a recent history of vaccination. This suggests that during these years there were a series of imported sporadic cases and outbreaks, confirming the findings of epidemiological data analysis. The importation sources were generally consistent with our geographic and cultural ties, mainly with Europe (genotypes 1E, 2B, 1I) and Latin America (1J). PMID:27622271

    Full Text Available Objective: rubella during the early stages of pregnancy can lead to severe birth defects known as congenital rubella syndrome (CRS. Samples collected from pregnant women with symptoms and suspected of congenital rubella infection between 1996 and 2008 were analyzed. Methods: a total of 23 amniotic fluid samples, 16 fetal blood samples, 1 product of conception and 1 placenta were analyzed by serology and RT-PCR. Results: all patients presented positive serology for IgG / IgM antibodies to rubella virus. Among neonates, 16 were IgG-positive, 9 were IgM-positive and 4 were negative for both antibodies. Of the 25 samples analyzed in this study, 24 were positive by RT-PCR. Changes in ultrasound were found in 15 (60% of 25 fetuses infected with rubella virus. Fetal death and miscarriage were reported in 10 (40% of the 25 cases analyzed. The rubella virus was amplified by PCR in all fetuses with abnormal ultrasound compatible with rubella. Fetal death and abortion were reported in 10 of 25 cases analyzed. Conclusion: this study, based on primary maternal rubella infection definitely confirms the good sensitivity and specificity of RT-PCR using amniotic fluid and ultrasound. The results showed that molecular assays are important tools in the early diagnosis of rubella and congenital rubella syndrome.

    Korea Atomic Energy Research Institute (KAERI) started the development of Mobile Multi-Purpose Reactor (MMR), which is a 10MWth gas-cooled reactor. MMR is aiming for maximizing mobility, high performance, durability and safety. This is in order to use the MMR for many purposes such as ship propulsion, train engine and so on. MMR generally uses helium Brayton cycle as a power conversion system since it can obtain very simple system arrangement with direct cycle. However, some researchers have proposed that the supercritical carbon dioxide (S-CO{sub 2}) Brayton cycle can be more efficient energy converting cycle for the high temperature gas cooled reactor (HTGR) and the very high temperature reactor (VHTR) system as well. Thus, this paper is to compare helium Brayton cycle to the S-CO{sub 2} Brayton cycle in terms of the efficiency while varying turbine inlet temperature (T. I. T). A cascaded S-CO{sub 2} cycle which had been proposed by Argonne National laboratory (ANL) was used as the S-CO{sub 2} Brayton cycle configuration. This cycle is to overcome the mismatch of temperature drop between reactor coolant and CO{sub 2} through the reactor heat exchanger (RHX). Our research team reviewed the ANL research by using the in-house codes developed by the Korea Advanced institute of Science and Technology (KAIST) research team. The calculation error between the in-house code and previous result was -0.36%.

    Integrated clinical whole-body PET/MR systems were introduced in 2010. In order to bring this technology into clinical usage, it is of great importance to compare the performance with the well-established PET/CT. The aim of this study was to evaluate PET performance, with focus on image quality, on Siemens Biograph mMR (PET/MR) and Siemens Biograph mCT (PET/CT). A direct quantitative comparison of the performance characteristics between the mMR and mCT system was performed according to National Electrical Manufacturers Association (NEMA) NU 2-2007 protocol. Spatial resolution, sensitivity, count rate and image quality were evaluated. The evaluation was supplemented with additional standardized uptake value (SUV) measurements. The spatial resolution was similar for the two systems. Average sensitivity was higher for the mMR (13.3 kcps/MBq) compared to the mCT system (10.0 kcps/MBq). Peak noise equivalent count rate (NECR) was slightly higher for the mMR (196 kcps @ 24.4 kBq/mL) compared to the mCT (186 kcps @ 30.1 kBq/mL). Scatter fractions in the clinical activity concentration range yielded lower values for the mCT (34.9 %) compared to those for the mMR (37.0 %). Best image quality of the systems resulted in approximately the same mean hot sphere contrast and a difference of 19 percentage points (pp) in mean cold contrast, in favour of the mCT. In general, point spread function (PSF) increased hot contrast and time of flight (TOF) increased both hot and cold contrast. Highest hot contrast for the smallest sphere (10 mm) was achieved with the combination of TOF and PSF on the mCT. Lung residual error was higher for the mMR (22 %) than that for the mCT (17 %), with no effect of PSF. With TOF, lung residual error was reduced to 8 % (mCT). SUV was accurate for both systems, but PSF caused overestimations for the 13-, 17- and 22-mm spheres. Both systems proved good performance characteristics, and the PET image quality of the mMR was close to that of the m

    Full Text Available The number of asylum seekers arriving in Germany has increased rapidly since 2014 and cases of vaccine-preventable diseases at reception centres were reported. Asylum seekers 12 years and older arriving in Lower Saxony were serologically screened for antibodies against measles, rubella and varicella between November 2014 and October 2015. We calculated the seroprevalence from the screening data by disease, country of origin and age group and compared them to literature-based herd immunity thresholds in order to identify immunisation gaps. In total, 23,647 specimens were included in our study. Although the vast majority of asylum seekers tested positive for antibodies against measles, rubella and varicella, the seroprevalences were not sufficient to ensure herd immunity. The seroprevalences varied substantially between countries of origin and increased with age. Immunisation of asylum seekers against measles, rubella and varicella is needed and the detailed information on seroprevalences among subgroups of asylum seekers can be used for targeted immunisations at reception centres.

    Full Text Available Abstract Background Despite the Government acting quickly to reassure parents about MMR safety following the publication of the 1998 paper by Wakefield and colleagues, MMR uptake declined. One of the reasons suggested for this decline is a loss of public trust in politicians and health professionals. The purpose of this analysis was to examine parents' views on the role the media, politicians and health professionals have played in providing credible evidence about MMR safety. Methods A qualitative focus group study conducted with parents living in Central Scotland. Eighteen focus groups were conducted with 72 parents (64 mothers and 8 fathers between November 2002 and March 2003. Purposive sampling was used to ensure maximum variation among parents. Results In the period after the MMR controversy, parents found it difficult to know who to trust to offer balanced and accurate information. The general consensus was that politicians were untrustworthy in matters of health. The motives of primary health care providers were suspected by some parents, who saw them as having a range of vested interests (including financial incentives. Among the sources of evidence seen by some parents as more credible were other parents, and Andrew Wakefield who was viewed as an important whistle-blower and champion of ordinary parents. Conclusion The provision of accurate information is only one aspect of helping parents make immunisation decisions. Establishing and maintaining trust in the information provided is also important. The MMR controversy may provide useful lessons for health professionals about trust and credibility that may be generalisable to future health controversies.

    Here we present rubella virus specific antibody levels in a large cross-sectional population-based serosurveillance study performed in The Netherlands in 2006/2007. In the nationwide sample, seroprevalence was high (95%). Higher levels of rubella specific antibodies were observed in the naturally infected cohorts compared with the vaccinated cohorts. After both vaccinations, the geometric mean concentration of rubella specific antibodies remained well above the protective level. However, antibody concentrations decreased faster after one than after two vaccinations. Infants too young to be vaccinated were a risk group in the nationwide sample. In the orthodox protestant group, individuals younger than 6 years of age were at risk for an infection with rubella, consistent with a small local outbreak that recently occurred at an orthodox protestant primary school. The general Dutch population is well protected against an infection with rubella virus. However, monitoring the rubella specific seroprevalence remains an important surveillance tool to assess possible groups at risk.

    Conclusion: Measles and rubella are 2 common communicable diseases in the children of Jingzhou District, with outbreaks being the main epidemic form. Some clinical features such as temperature, duration of the prodromal stage and exanthema are different in measles and rubella, and they can be useful in distinguishing between the 2 diseases. Accuracy in the clinical diagnosis of measles should be improved by enhancing serologic testing for measles and rubella, and by identifying patients' specific clinical characteristics.

    In 2013, a rubella outbreak was observed in Japan, Romania, and Poland. The outbreak in Japan was accompanied by an increase of measles reports, especially from a region where measles is highly controlled. This was attributed to the adult populations affected by this rubella outbreak, similarity of clinical signs between rubella and measles, sufficiently small impact of measles outbreaks from neighboring nations, and elimination levels of measles endemicity. Current and future concerns for measles control are discussed.

    Rubella virus is the causative agent of rubella. The symptoms are usually mild, and characterized by a maculopapular rash and fever. However, rubella infection in pregnant women sometimes can result in the birth of infants with congenital rubella syndrome (CRS). Global efforts have been made to reduce and eliminate CRS. Although a reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay for detection of rubella virus has been reported, the primers contained several mismatched nucleotides with the genomes of currently circulating rubella virus strains. In the present study, a new RT-LAMP assay was established. The detection limit of this assay was 100-1000PFU/reaction of viruses for all rubella genotypes, except for genotype 2C, which is not commonly found in the current era. Therefore, the new RT-LAMP assay can successfully detect all current rubella virus genotypes, and does not require sophisticated devices like TaqMan real-time PCR systems. This assay should be a useful assay for laboratory diagnosis of rubella and CRS.

    Global prevention and control of infectious diseases requires significant investment of financial and human resources and well-functioning leadership and management structures. The reality of competing demands for limited resources leads to trade-offs and questions about the relative value of specific investments. Developing investment cases can help to provide stakeholders with information about the benefits, costs, and risks associated with available options, including examination of social, political, governance, and ethical issues. We describe the process of developing investment cases for globally coordinated management of action plans for measles and rubella as tools for enabling the implementation of the Global Vaccine Action Plan (GVAP). We focus on considerations related to the timing of efforts to achieve measles and rubella goals independently and within the context of ongoing polio eradication efforts, other immunization priorities, and other efforts to control communicable diseases or child survival initiatives. Our analysis suggests that the interactions between the availability and sustainability of financial support, sufficient supplies of vaccines, capacity of vaccine delivery systems, and commitments at all levels will impact the feasibility and timing of achieving national, regional, and global goals. The timing of investments and achievements will determine the net financial and health benefits obtained. The methodology, framing, and assumptions used to characterize net benefits and uncertainties in the investment cases will impact estimates and perceptions about the value of prevention achieved overall by the GVAP. We suggest that appropriately valuing the benefits of investments of measles and rubella prevention will require the use of integrated dynamic disease, economic, risk, and decision analytic models in combination with consideration of qualitative factors, and that synthesizing information in the form of investment cases may help

    In late 2014, a measles outbreak beginning in California received significant media attention. To better understand the impact of this outbreak, we conducted a survey to assess and compare among vaccine hesitant and non-hesitant new mothers how this outbreak affected vaccine knowledge, attitudes, vaccination plans, and media use. A cross-sectional email survey of English-speaking women with a child ⩽1year old using a convenience sample of women from nine obstetrics and gynecology (OB/GYN) practices in Colorado assessed vaccine hesitancy, knowledge and attitudes about MMR vaccines and the outbreak, MMR vaccination plans before and after the outbreak, and use of and trust for media sources related to the outbreak. The response rate was 50% (351/701). Knowledge about the outbreak was high and vaccination attitudes were mostly favorable. Forty-eight percent of respondents thought MMR vaccine was more important after the outbreak. Online news (76%), television news (75%), and social media (68%) were the most frequently used media sources, yet were highly trusted by only 18%, 22%, and 1% of respondents respectively. Government websites (34%) and information from a doctor's office (34%) were infrequently used, but were highly trusted by 62% and 60% of respondents. Knowledge of the outbreak was lower among vaccine-hesitant respondents. Few mothers changed MMR vaccination plans after the outbreak. New mothers had high levels of knowledge and favorable attitudes about vaccination after the 2014-15 measles outbreak. Media sources used the most are not the most trusted. Communication about outbreaks of vaccine-preventable diseases should include spread of accurate information to new media sources and strengthening of existing trust in traditional media.

    Full Text Available Abstract Background 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. Methods An open-label randomised trial was performed in France and Germany. Healthy children, aged 12 to18 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. Results 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 ≥ 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 (≤ 2.5 cm. There was a trend for lower rates of injection-site erythema and swelling in the IM group. The incidence and nature of systemic adverse events were comparable for the two routes

    Full Text Available Rubella is an acute, contagious viral infection caused by a teratogenic enveloped single-stranded RNA virus, rubella virus, a member of the togaviridae family. Though causing generally mild infections in children and adults, it is a disease of public health importance in pregnant women causing major problems including abortions, miscarriages and Congenital Rubella Syndrome in more than twenty per cent of the susceptible population. This study was carried out to determine the characteristics associated with rubella seronegativity amongst female blood donors in Zambia. Rubella-specific IgG antibody levels were measured in the blood serum. Proportions were compared using the Chi-squared test at the 5% significance level, and magnitudes of associations were determined using the odds ratio and its 95% confidence interval. Of the 124 female blood donors tested for rubella IgG 46.0% were aged less than 20 years. Overall, 66.7% of the participants had never been married. More than half (62.1% of the participants resided in rural areas of the country. Of the 114 participants with recorded level of education, 50.1% had at–least completed secondary school. Out of 43 participants with recorded current employment status, 44.2% were not working for pay. A total of 10 (8.1% participants were sero-negative to rubella IgG antibodies. No factors were associated with seronegativity. Protection against rubella through natural infection appears inadequate to protect the population, increasing the risk of CRS.

Spread and identifiation of rubella genotypes in Indonesia is important to ensure the indigenous or importation virus. The purpose of this study was to determine the rubella genotype distribution and spread in West Java in effective prevention efforts. This study was conducted by examining the urine samples of suspect measles patients using WHO protocol through the virus isolation in vero cells, PCR, DNA sequencing, and analysis of the sequencing results. Samples taken from the measles-rubella surveillance program nationwide in 2011 ̶ 2013. Of the 251 urine samples were examined, 32 samples (12.7% were positive. A total of 28 cases (87.5% were genotype 1E while the remaining 4 cases (12.5% were genotype 2B. Rubella virus spread primarily occurs in District of Kuningan, Garut, Tasikmalaya, Bandung City, Cimahi City, and Tasikmalaya City. Prevention of the rubella diseases and CRS surveillance in endemic areas should be priority task to break the chain of transmission.

    In 2012, the World Health Assembly endorsed the Global Vaccine Action Plan (GVAP)* with the objective to eliminate measles and rubella in five World Health Organization (WHO) regions by 2020. In September 2013, countries in all six WHO regions had established measles elimination goals, and additional goals for elimination of rubella and congenital rubella syndrome were established in three regions (1). Capacity for surveillance, including laboratory confirmation, is fundamental to monitoring and verifying elimination. The 2012-2020 Global Measles and Rubella Strategic Plan of the Measles and Rubella Initiative(†) calls for effective case-based surveillance with laboratory testing for case confirmation (2). In 2000, the WHO Global Measles and Rubella Laboratory Network (GMRLN) was established to provide high quality laboratory support for surveillance (3). The GMRLN is the largest globally coordinated laboratory network, with 703 laboratories supporting surveillance in 191 countries. During 2010-2015, 742,187 serum specimens were tested, and 27,832 viral sequences were reported globally. Expansion of the capacity of the GMRLN will support measles and rubella elimination efforts as well as surveillance for other vaccine-preventable diseases (VPDs), including rotavirus, and for emerging pathogens of public health concern.

    Substantial progress has been made in the World Health Organization (WHO) European Region toward reaching the goal of measles and rubella elimination. We analyzed the surveillance data of 2012 on measles and rubella for age-group, diagnosis confirmation status (clinical, laboratory-confirmed and epidemiologically linked), vaccination status, and measles-related deaths. For 2012, there were 23,871 measles cases and 29,361 rubella cases reported in the region, mostly among unvaccinated persons. Almost one in three patients with measles and one in five patients with rubella were aged 20 years and older. In a few countries, widespread outbreaks or indigenous transmission of measles persisted in 2012. While most countries in the region have controlled rubella, a small number still reported a high incidence and several outbreaks. Therefore, more efforts are required to achieve the goal of eliminating measles and rubella in the WHO European Region by 2015, particularly in high-incidence countries. The WHO measles and rubella elimination plan stipulates that all countries should achieve and maintain the required high vaccination coverage while conducting high-quality surveillance.

    The Laboratory is a fundamental component on the surveillance of measles and rubella. Cases need to be properly confirmed to ensure an accurate estimation of the incidence. Strains should be genetically characterized to know the transmission pattern of these viruses and frequently, outbreaks and transmission chains can be totally discriminated only after that. Finally, the susceptibility of the population is estimated on the basis of sero-prevalence surveys. Detection of specific IgM response is the base of the laboratory diagnosis of these diseases. It should be completed with genomic detection by RT-PCR to reach an optimal efficiency, especially when sampling is performed early in the course of the disease. Genotyping is performed by genomic sequencing according to reference protocols of the WHO. Laboratory surveillance of measles and rubella in Spain is organized as a net of regional laboratories with different capabilities. The National Center of Microbiology as National Reference Laboratory (NRL), supports regional laboratories ensuring the availability of all required techniques in the whole country and watching for the quality of the results. The NRL is currently working in the implementation of new molecular techniques based on the analysis of genomic hypervariable regions for the strain characterization at sub-genotypic levels and use them in the surveillance.

    Previous studies have suggested that a child's sex may be a predictor of vaccine reactions. We used a self-controlled case series design, an extension of retrospective cohort methodology which controls for fixed confounders using a conditional Poisson modeling approach. We compared a risk period immediately following vaccination to a control period farther removed from vaccination in each child and estimated the relative incidence of emergency room visits and/or hospital admissions following the 2-, 4-, 6-, and 12-month vaccinations to investigate the effect of sex on relative incidence. All infants born in Ontario, Canada between April 1, 2002 and March 31, 2009 were eligible for study inclusion. In analyses combining immunizations at 2, 4 and 6 months and examining these vaccinations separately, there was no significant relationship between the relative incidence of an event and sex of the child. At 12 months, we observed a significant effect of sex, with female sex being associated with a significantly higher relative incidence of events (P=0.0027). The relative incidence ratio (95% CI) comparing females to males following the 12-month vaccination was 1.08 (1.03 to 1.14), which translates to 192 excess events per 100,000 females vaccinated compared to the number of events that would have occurred in 100,000 males vaccinated. As the MMR vaccine is given at 12 months of age in Ontario, our findings suggest that girls may have an increased reactogenicity to the MMR vaccine which may be indicative of general sex differences in the responses to the measles virus.

    A comparative descriptive study was conducted to determine the effectiveness of text messages with pictures compared with plain text messages or verbal reminders in improving measles, mumps, and rubella immunization compliance in the rural areas of the Philippines. We found that text messaging with or without pictures is a feasible and useful tool in measles, mumps, rubella immunization compliance for childhood immunization. Texting with pictures (n = 23), however, was no more effective than plain text messaging (n = 19) or verbal reminder (n = 17) in improving measles, mumps, and rubella immunization compliance. Compared with parents who received verbal reminders alone, either type of text reminders was linked to parents bringing their child for measles, mumps, and rubella immunization on a timelier basis, as defined by the difference between the scheduled visit and the actual visit, although this was not statistically significant. Mobile technology that uses text reminders for immunization can potentially improve the communication process between parent, the public health nurse, and healthcare provider. Future studies can explore the application of plain text messages or text messages with pictures to improve compliance more broadly for maternal and child healthcare especially in rural areas of developing countries and may be a helpful tool for health promotion for this population.

  10. Genomic identification of founding haplotypes reveals the history of the selfing species Capsella rubella.

    Yaniv Brandvain

    Full Text Available The shift from outcrossing to self-fertilization is among the most common evolutionary transitions in flowering plants. Until recently, however, a genome-wide view of this transition has been obscured by both a dearth of appropriate data and the lack of appropriate population genomic methods to interpret such data. Here, we present a novel population genomic analysis detailing the origin of the selfing species, Capsella rubella, which recently split from its outcrossing sister, Capsella grandiflora. Due to the recency of the split, much of the variation within C. rubella is also found within C. grandiflora. We can therefore identify genomic regions where two C. rubella individuals have inherited the same or different segments of ancestral diversity (i.e. founding haplotypes present in C. rubella's founder(s. Based on this analysis, we show that C. rubella was founded by multiple individuals drawn from a diverse ancestral population closely related to extant C. grandiflora, that drift and selection have rapidly homogenized most of this ancestral variation since C. rubella's founding, and that little novel variation has accumulated within this time. Despite the extensive loss of ancestral variation, the approximately 25% of the genome for which two C. rubella individuals have inherited different founding haplotypes makes up roughly 90% of the genetic variation between them. To extend these findings, we develop a coalescent model that utilizes the inferred frequency of founding haplotypes and variation within founding haplotypes to estimate that C. rubella was founded by a potentially large number of individuals between 50 and 100 kya, and has subsequently experienced a twenty-fold reduction in its effective population size. As population genomic data from an increasing number of outcrossing/selfing pairs are generated, analyses like the one developed here will facilitate a fine-scaled view of the evolutionary and demographic impact of the

    Rubella is generally a mild childhood disease, but infection during early pregnancy may cause spontaneous abortion or congenital rubella syndrome (CRS), which may entail a variety of birth defects. Since vaccination at levels short of those necessary to achieve eradication may increase the average age of infection, and thus potentially the CRS burden, introduction of the vaccine has been limited to contexts where coverage is high. Recent work suggests that spatial heterogeneity in coverage sh...

    In accordance with the goal of the World Health Organization Regional Office for Europe, the Italian national measles and rubella elimination plan aims to reduce the incidence of congenital rubella cases to less than one case per 100,000 live births by the end of 2015. We report national surveillance data for congenital rubella and rubella in pregnancy from 2005 to 2013. A total of 75 congenital rubella infections were reported; the national annual mean incidence was 1.5/100,000 live births, including probable and confirmed cases according to European Union case definition. Two peaks occurred in 2008 and 2012 (5.0 and 3.6/100,000 respectively). Overall, 160 rubella infections in pregnancy were reported; 69/148 women were multiparous and 38/126 had had a rubella antibody test before pregnancy. Among reported cases, there were 62 infected newborns, 31 voluntary abortions, one stillbirth and one spontaneous abortion. A total of 24 newborns were unclassified and 14 women were lost to follow-up, so underestimation is likely. To improve follow-up of cases, systematic procedures for monitoring infected mothers and children were introduced in 2013. To prevent congenital rubella, antibody screening before pregnancy and vaccination of susceptible women, including post-partum and post-abortum vaccination, should be promoted. Population coverage of two doses of measles-mumps-rubella vaccination of ≥ 95% should be maintained and knowledge of health professionals improved.

    2012-01-01

    The paper of Wakefield et al. in The Lancet, triggered a negative reaction to the MMR vaccine, even though it was just a series of cases and the association between vaccination and autism could well be anecdotal. However, it was found that this association was spurious, not only because of hidden biases but also to alterations of the data and other improper behavior of the two authors that they were expelled from medical council. Finally, the article was removed from the magazine. This episode invites to think about the credibility and trust in the authorities and professionals to the population, as well as the suspicions that may arise when there are potential conflicts of interest among professionals, industry magazines and the population. A special area of interest is on the distorted expectations of health interventions, including vaccination, particularly with regard to both individual and collective prevention.

    Pre-clinical data suggested a relationship between inactivation of hMLH1 and hMSH2 and resistance to drugs like cisplatin and carboplatin, but not oxaliplatin. We then hypothesised that NSCLC showing loss of expression of the mismatch repair system (MMR), could be refractory to cisplatin-based, but not to oxaliplatin-based chemotherapy. Immunohistochemical expression of hMLH1 and hMSH2 was analysed on tumour samples from 93 advanced NSCLC, receiving chemotherapy with either cisplatin or oxaliplatin in combination with gemcitabine. Patients showing loss of hMLH1 or hMSH2 expression in > or = 50% of tumour cells were deemed MMR-negative (Group A), whereas cases with a normal hMLH1 or hMSH2 expression in > 50% of the tumour cells were defined MMR-positive (Group B). No differences in the response and progression rate were found in the whole patients population and in the gemcitabine/cisplatin group for both hMLH1 and hMSH2. In the gemcitabine/oxaliplatin group response rate was 38% and 0% (p=0.04) for patients with or without loss of hMSH2 expression. Median survival according to MMR status in Groups A and B, respectively was: 17 months versus 9 months for hMLH1 (p=0.031) and 10 months versus 9 months for hMSH2 (p=0.8330). Both the difference in response rate and in median survival observed according to MMR status seem to confirm what has been suggested by preclinical studies.

    vaccine protects 70 to 90% of immunized children against any form of varicella zoster infection, but the efficacy against severe forms is higher (95 to 98%. This is a well-tolerated vaccine that causes few reactions. Since the vaccine was licensed, there have been three confirmed cases of transmission of the vaccine virus by domestic contacts to previously healthy people, who went on to develop mild disease. Despite evidence that the protection offered by this vaccine can wane over a number of years, it is not yet possible to state that a second dose is warranted, bearing in mind exposure to wild virus. After universal vaccination the chances of natural stimulation should drop and it is very probable that booster doses will become necessary. A measles, mumps, rubella, and varicella vaccine has recently been licensed that combines vaccines for measles, mumps, rubella and varicella in a single product with high rates of seroconversion. CONCLUSIONS: The Brazilian Society of Pediatrics recommends the varicella vaccine for children from 1 year on. We hope that the measles, mumps, rubella, and varicella vaccine will soon be available in Brazil, since combined vaccines facilitate wider vaccination coverage.

    We determined the prevalence of anti-rubella antibodies in 100 serum samples from pregnant women who attended routine examination at a private institution in the city of Córdoba, and in 100 serum samples from women of gestational age, 42 of whom were pregnant, attending health centres in the city of Villa Mercedes, province of San Luis. IgG antibodies against parvovirus 819 were also determined in the serum samples from Córdoba. Using the hemmagglutination inhibition test, we found a 98% prevalence of anti-rubella antibodies among pregnant women in Córdoba and of 96% among the women in Villa Mercedes, whereas the prevalence of anti-parvovirus 819 was 66% in the serum samples from Cordoba. These results coincide with those reported for other cities in the world, and establish an interest in continuing similar studies in order to monitor the immunization plan, which in Argentina has been going on since 1997. They also suggest the importance of the determination of IgM anti-parvovirus B19 in pregnant women who are symptomatic but with a negative result for rubella.

    Rubella virus (RUBV) replicons expressing a drug resistance gene and a gene of interest were used to select cell lines uniformly harboring the replicon. Replicons expressing GFP and a virus capsid protein GFP fusion (C-GFP) were compared. Vero or BHK cells transfected with either replicon survived drug selection and grew into a monolayer. However, survival was {approx}9-fold greater following transfection with the C-GFP-replicon than with the GFP-expressing replicon and while the C-GFP-replicon cells grew similarly to non-transfected cells, the GFP-replicon cells grew slower. Neither was due to the ability of the CP to enhance RNA synthesis but survival during drug selection was correlated with the ability of CP to inhibit apoptosis. Additionally, C-GFP-replicon cells were not cured of the replicon in the absence of drug selection. Interferon-alpha suppressed replicon RNA and protein synthesis, but did not cure the cells, explaining in part the ability of RUBV to establish persistent infections.

    Full Text Available PURPOSE: To describe the ocular manifestations of congenital rubella syndrome (CRS, a common cause of congenital cataracts in developing countries. METHODS: Retrospective analysis of case records of 46 sero-positive infants under 12 months of age who presented at Aravind Eye Hospital, Madurai between July 1993 and February 2001. The ocular and systemic examination details were recorded. RESULTS: Both eyes were affected in 41 (89% patients. Cataract was present in 81 (93.1% eyes; most of them were nuclear cataract (79, 97.5%. Other common ocular presentations included microphthalmos in 74 (85.1% eyes, iris abnormalities in 51 (58.6% eyes, and pigmentary retinopathy in 33 (37.9% eyes. Cataract, microphthalmos and iris hypoplasia was a common combination present in 49 (56.3% eyes. Systemic manifestations included cardiac anomalies in 23 (50% and neurological anomalies in 16 (34% children. Multi-system involvement was present in 32 (70% children. Low birth weight (below 2 kg was seen in 30% infants. CONCLUSION: CRS may present with a wide spectrum of ocular and systemic findings and requires a high index of suspicion for diagnosis. Any sick infant with unilateral or bilateral congenital cataract should be investigated thoroughly for CRS.

    Full Text Available One hundred and seventy five apparently normal asymptomatic pregnant women were studied prospectively and 247 women with different complications of pregnancy were screened at the time of delivery for infections like Chlamydia trachomatis, Toxoplasma, Rubella and cytomegalovirus (CMV. One hundred and forty two women with normal outcome of pregnancy served as controls. Specific IgM due to these agents were determined in the sera using commercial diagnostic kits. Results of the study showed that chlamydial infection was the most prevalent (29.8% followed by Toxoplasmosis (13.1, Rubella (6.5% and CMV (5.8%. Adverse outcome was seen among those seropositive for Chlamydia, Toxoplasmosis and Rubella. CMV showed no association with adverse outcome of pregnancy. Since Chlamydia and Toxoplasmosis are amenable to treatment with antibiotics, screening for these infections and appropriate treatment would improve outcome of pregnancy.

    The role that virus infections play in autism is not known. Others have reported that antibodies against measles virus are higher in the sera/plasma of children with autism versus controls. The authors investigated antibody titers to measles, mumps, and rubella viruses and diphtheria toxoid in children with autism, both classic onset (33) and regressive onset (26) forms, controls (25, healthy age- and gender-matched) and individuals with Tourette's syndrome (24) via enzyme-linked immunosorbent assays. No significant differences in antibody titers to measles, mumps, and rubella viruses and diphtheria toxoid were found among the four groups. Additionally, there were no significant differences between the four groups for total immunoglobulin (Ig)G or IgM. Interestingly, the authors did find a significant number (15/59) of autism subjects (classic and regressive onset combined) who had a very low or no antibody titer against rubella virus, compared to a combine control/Tourette's group (2/49).

    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.

    In 1974, Japanese scientists developed a live attenuated varicella vaccine based on the Oka strain. The efficacy of the vaccine for the prevention of varicella has been primarily demonstrated in studies conducted in the United States following the adoption of universal immunization using the Oka strain varicella vaccine in 1996. Although the vaccine was developed by Japanese scientists, until recently, the vaccine has been administered on a voluntary basis in Japan resulting in a vaccine coverage rate of approximately 40%. Therefore, Japan initiated universal immunization using the Oka strain varicella vaccine in November 2014. Given the transition from voluntary to universal immunization in Japan, it will also be important to monitor the epidemiology of varicella and herpes zoster. The efficacy and safety of co-administration of the varicella vaccine and measles, mumps, and rubella vaccine have been demonstrated in many countries; however, there was no data from Japan. In order to adopt the practice of universal immunization using the Oka strain varicella vaccine in Japan, data demonstrating the efficacy and safety of co-administration of varicella vaccine and measles and rubella (MR) vaccine were required. Additionally, we needed to elucidate the appropriate time interval between the first and second administrations of the vaccine. It is also important to differentiate between wild type and Oka vaccine type strains in herpes zoster patient with past history of varicella vaccine. Thus, there are many factors to consider regarding the adoption of universal immunization in Japan to control varicella zoster virus (VZV) infections.

    The steam Rankine cycle has been mainly applied in the Power Conversion Unit (PCU) of the existing SMRs. For this reason, modularization and downsizing of the nuclear power plant including PCU is difficult due to complexity and large volume. To solve these problems, KAIST research team proposed a new concept of SMR, called KAIST MMR (Micro Modular Reactor), which utilizes S-CO2 as the working fluid. Due to high density of S-CO2 and the development of heat exchanger technology, such as the printed circuit heat exchanger (PCHE), it can achieve small PCU and modularization of system. This paper describes the method of performance maps to predict the turbomachinery performance for different inlet conditions. One of the most well-known methods is equivalent conditions which include corrected mass flow, corrected total enthalpy rise, and corrected speed. Appropriate performance at any conditions which are different from the design condition can be calculated. As further works, the predicted data from KAIST{sub T}MD will be compared to other experimental data. Also turbine code will be validated.

    This study assessed the usefulness of email in informing third level students about special MMR clinics being provided on campus during a mumps outbreak in the North West of Ireland. Email messages were sent directly to students, informing them of the clinics, inviting them to make a clinic appointment by email and providing details of walk-in clinics. At the clinics, all 177 attendees were asked to fill out a questionnaire and the response rate was 89% (n=158). Regarding the main sources of information about the vaccination clinics, email was selected by 117 (74%) students, word-of-mouth by 27 (17%), posters\\/leaflets by 8 (5%), and other sources by 6 (4%). Use of email as a source of information was rated as very good\\/excellent by 115 (73%), as good by 35 (22%) and poor\\/fair by 8 (5%). This study demonstrates that email is a useful and acceptable way of informing third level students about immunisation clinics in an outbreak situation.

Regarding the main sources of information about the vaccination clinics, email was selected by 117 (74%) students, word-of-mouth by 27 (17%), posters/leaflets by 8 (5%), and other sources by 6 (4%). Use of email as a source of information was rated as very good/excellent by 115 (73%), as good by 35 (22%) and poor/fair by 8 (5%). This study demonstrates that email is a useful and acceptable way of informing third level students about immunisation clinics in an outbreak situation.

    Rubella is usually a mild disease with nonspecific symptoms, but can cause congenital rubella syndrome (CRS) when infection occurs during pregnancy. The objective of this study was to evaluate the sensitivity and positive predictive value of different data sources used for surveillance purposes in the Rubella Elimination Program of Catalonia between 2002 and 2011. The Urgent Notification to the Statutory Disease Reporting System, the Individualized Disease Reporting System, screening for other viruses included in the Measles Elimination Program, the Microbiological Reporting System and the Minimum Hospital Discharge Data were evaluated. 100 suspected cases of postnatal rubella and 6 suspected cases of CRS were detected. For postnatal rubella, Urgent Notification had the highest sensitivity (32.5%; 95%CI 18.6-49.1), followed by the Virus screening in Measles Elimination Program (25%; 95%CI 12.7-41.2). Virus screening in the Measles Elimination Program had the highest PPV (76.9%; 95%CI 46.1-94.9), followed by the Individualized Disease Reporting System (57.1%; 95%CI 28.9-82.3). For CRS cases, the Individualized Disease Reporting System had the highest sensitivity (100%, 95%CI 29.2-100) and the highest PPV (60%; 95%CI 14.7-100). Most confirmed postnatal cases (25 cases, 48.1%) were in the 25-44 y age group followed by the 15-24 y age group (11 cases, 21.2%). The highest values of sensitivity and PPV for the detection of confirmed cases corresponded to activities that were specifically introduced in the measles and rubella elimination programs.

    DNA复制是一个严谨有序的过程,细胞分裂时,碱基错配的概率约为1/1010~1/109.错配修复系统(MMR)是一个从细菌到真核细胞皆保守的DNA修复途径,它负责修复DNA中错配的碱基,或者DNA聚合酶的校对功能失调而引起的复制错误,插入,遗失碱基,使DNA整体复制的保真度增加50~1000倍.MMR系统失控会导致DNA序列中微卫星序列的不稳定性(MSI)或编码功能蛋白的基因突变,改变正常细胞功能,从而引发肿瘤.%DNA replication is an extraordinarily faithful process, mutation occures at a frequency of 1/10 or 1/10 base pairs per cell division. The MMR pathway, a DNA repair pathway conserved from bacteria to humans, targets base substitution mismatches and insertion-deletion mismatches that arise as a result of replication errors that escape the proofreading function of DNA polymerases. In doing so, MMR contributes an additional 50 ~ 1000-fold to the o-verall fidelity of replication. Thus, inactivation of MMR confers a strong mutated phenotype in which the rate of spontaneous mutation is greatly elevated,such as microsatellite stability (MSI) , or mutated genes that code functional proteins, thus give rise to cancer.

    The use of temozolomide (TMZ) has improved the prognosis for glioblastoma multiforme patients. However, TMZ resistance may be one of the main reasons why treatment fails. Although this resistance has frequently been linked to the expression of O6-methylguanine-DNA methyltransferase (MGMT) it seems that this enzyme is not the only molecular mechanism that may account for the appearance of drug resistance in glioblastoma multiforme patients as the mismatch repair (MMR) complex, P-glycoprotein, and/or the presence of cancer stem cells may also be implicated. Four nervous system tumor cell lines were used to analyze the modulation of MGMT expression and MGMT promoter methylation by TMZ treatment. Furthermore, 5-aza-2'-deoxycytidine was used to demethylate the MGMT promoter and O(6)-benzylguanine to block GMT activity. In addition, MMR complex and P-glycoprotein expression were studied before and after TMZ exposure and correlated with MGMT expression. Finally, the effect of TMZ exposure on CD133 expression was analyzed. Our results showed two clearly differentiated groups of tumor cells characterized by low (A172 and LN229) and high (SF268 and SK-N-SH) basal MGMT expression. Interestingly, cell lines with no MGMT expression and low TMZ IC50 showed a high MMR complex expression, whereas cell lines with high MGMT expression and high TMZ IC50 did not express the MMR complex. In addition, modulation of MGMT expression in A172 and LN229 cell lines was accompanied by a significant increase in the TMZ IC50, whereas no differences were observed in SF268 and SK-N-SH cell lines. In contrast, P-glycoprotein and CD133 was found to be unrelated to TMZ resistance in these cell lines. These results may be relevant in understanding the phenomenon of TMZ resistance, especially in glioblastoma multiforme patients laking MGMT expression, and may also aid in the design of new therapeutic strategies to improve the efficacy of TMZ in glioblastoma multiforme patients.

    A case of duplication of the mental nerve in a patient with cleft lip, cleft palate, and rubella syndrome is presented. The most vulnerable period of fetal infection by rubella virus corresponds with the critical period of development of the maxilla, mandible, and corresponding orofacial structures. The significance of duplication of the mental nerve is discussed in relation to the influence that this anatomic structure has on the growth and development of the mandible. The concept of activisms to explain such anomalies is reviewed.

    We conducted a nationwide survey to assess measles containing vaccine (MCV) coverage among children aged 1-9 years in Haiti and identify factors associated with vaccination before and during the 2012 nationwide supplementary immunisation activities (SIA). Haiti was stratified into five geographic regions (Metropolitan Port-au-Prince, North, Centre, South and West), 40 clusters were randomly selected in each region, and 35 households were selected per cluster. Among the 7000 visited households, 75.8% had at least one child aged 1-9 years; of these, 5279 (99.5%) households consented to participate in the survey. Of 9883 children enrolled, 91% received MCV before and/or during the SIA; 31% received MR for the first time during the SIA, and 50.7% received two doses of MCV (one before and one during the 2012 SIA). Among the 1685 unvaccinated children during the SIA, the primary reason of non-vaccination was caregivers not being aware of the SIA (31.0%). Children aged 1-4 years had significantly lower MR SIA coverage than those aged 5-9 years (79.5% vs. 84.8%) (P < 0.0001). A higher proportion of children living in the West (12.3%) and Centre (11.2%) regions had never been vaccinated than in other regions (4.8-9.1%). Awareness, educational level of the mother and region were significantly associated with MR vaccination during and before the SIA (P < 0.001). The 2012 SIA successfully increased MR coverage; however, to maintain measles and rubella elimination, coverage needs to be further increased among children aged 1-4 years and in regions with lower coverage. © 2014 John Wiley & Sons Ltd.

    All measles-containing vaccines are associated with several types of adverse events, including seizure, fever, and immune thrombocytopenia purpura (ITP). Because the measles-mumps-rubella-varicella (MMRV) vaccine compared with the separate measles-mumps-rubella (MMR) and varicella (MMR + V) vaccine increases a toddler's risk for febrile seizures, we investigated whether MMRV is riskier than MMR + V and whether either vaccine elevates the risk for additional safety outcomes. Study children were aged 12 to 23 months in the Vaccine Safety Datalink from 2000 to 2012. Nine study outcomes were investigated: 7 main outcomes (anaphylaxis, ITP, ataxia, arthritis, meningitis/encephalitis, acute disseminated encephalomyelitis, and Kawasaki disease), seizure, and fever. Comparing MMRV with MMR + V, relative risk was estimated by using stratified exact binomial tests. Secondary analyses examined post-MMRV or MMR + V risk versus comparison intervals; risk and comparison intervals were then contrasted for MMRV versus MMR+V. We evaluated 123,200 MMRV and 584,987 MMR + V doses. Comparing MMRV with MMR + V, risks for the 7 main outcomes were not significantly different. Several outcomes had few or zero postvaccination events. Comparing risk versus comparison intervals, ITP risk was higher after MMRV (odds ratio [OR]: 11.3 [95% confidence interval (CI): 1.9 to 68.2]) and MMR + V (OR: 10 [95% CI: 4.5 to 22.5]) and ataxia risk was lower after both vaccines (MMRV OR: 0.8 [95% CI: 0.5 to 1]; MMR + V OR: 0.8 [95% CI: 0.7 to 0.9]). Compared with MMR + V, MMRV increased risk of seizure and fever 7 to 10 days after vaccination. This study did not identify any new safety concerns comparing MMRV with MMR + V or after either the MMRV or the MMR + V vaccine. This study provides reassurance that these outcomes are unlikely after either vaccine. Copyright © 2015 by the American Academy of Pediatrics.

    Full Text Available Purpose. Congenital rubella syndrome (CRS is a global cause of preventable hearing impairment, blindness, and intellectual impairment. The present study sought to identify ocular and auditory manifestations of CRS in school-aged children in Mbingo, Cameroon. Design. Cross sectional study. Subjects. Students at two schools, one for children with hearing impairment, were screened for cataract, congenital glaucoma, and pigmentary retinopathy. Methods. Students underwent seven-field digital fundus photography through a dilated pupil using a Topcon NW200 nonmydriatic camera. Images were assessed by retina specialists in Canada via teleophthalmology. Clinical evidence was integrated to form case definitions for CRS based on Center for Disease Control and Prevention guidelines. Serological evidence of rubella infection was obtained using standardized IgG antibody titers. Main Outcome Measure. Number of probable and suspicious cases of CRS. Results. Between September 2009 and May 2010, 320 students participated. There were 28 (10.2% probable cases, 104 (37.8% suspects, and 143 (52.0% unaffected. Rubella IgG serology was positive in 79 (48.7% of children with hearing impairment and 11 (7.4% of children with normal hearing. Conclusions. The present study identified 28 probable cases of CRS. Furthermore, 92.6% of students with normal hearing did not possess rubella IgG antibodies making future cases of CRS likely without intervention.

    Full Text Available Background: Infections caused by Toxoplasma gondii, Rubella virus and Cytomegalovirus are major causes of Bad Obstetric History (BOH. Cause of BOH may be genetic, hormonal, abnormal maternal immune response, and maternal infection. Women affected with any of these diseases during pregnancy are at high risk for miscarriage, stillbirth, or for a child with serious birth defects and/or illness and also a hazard to attending staff nurses. Methods: A total 96 serum samples were collected from antenatal women with BOH attending the out-patient services of department of gynaecology at NRI general hospital, Chinakakani, Guntur district, Andhra Pradesh. Serum samples were obtained and were subjected to screening for Immunoglobulin M (IgM and Immunoglobulin G (IgG antibodies of Toxopalsma gondii, Rubella Virus and CMV infections by VIDAS (bioMerieux, France and Nanoplex ToRCH Screen kit [Lilac Medicare (P Ltd, Maharastra, India]. Results: Majority of cases with BOH were found in females aged 18-23 years (25, 52.08% followed by 24-29 years (18, 37.5%. Congenital anomalies and other complications were found to be more in age group 18-23 years followed by 24-29 years. The disease prevalence as studied with respect to IgM antibodies was found to be 31.25% for Cytomegalovirus Infections, 23.96% for Toxoplasma gondii, 21.88% for Rubella virus infections. The overall agreement in the Sensitivity, Specificity, Positive Predictive Value (PPV and Negative Predictive Value (NPV between VIDAS and Nanoplex ToRCH Screen kit for the detection of specific IgM and IgG antibodies in our study was excellent with sensitivity ranging from 90.91%-96.00% and specificity ranging from 89.47%-95.59% for the detection of IgM and IgG antibodies. The discrepancies were relatively less with 8.3% for CMV IgM, 6.2% for CMV IgG, 5.20% for Rubella IgM, 6.25% for Rubella IgG, 6.25% for Toxo IgM and 5.20% for Toxo IgG. Conclusion: Nanoplex ToRCH Screen Kit is a cheap, cost effective

    Full Text Available As a result of successful implementation of the measles/rubella elimination program, the etiology of more and more double negative cases remains elusive. The present study determined the role of different viruses as causative agents in measles or rubella suspected cases in Belarus. A total of 856 sera sent to the WHO National Laboratory between 2009 and 2011 were tested for specific IgM antibodies to measles virus (MV, rubella virus (RV and human parvovirus B19 (B19V. The negatives were further investigated for antibodies to enterovirus (EV and adenovirus (AdV. Children of up to 3 years were tested for IgM antibodies to human herpesvirus 6 (HHV6. A viral etiology was identified in 451 (52.7% cases, with 6.1% of the samples being positive for MV; 2.6% for RV; 26.2% for B19V; 9.7% for EV; 4.6% for AdV; and 3.6% for HHV6. Almost all measles and rubella cases occurred during limited outbreaks in 2011 and nearly all patients were at least 15 years old. B19V, EV and AdV infections were prevalent both in children and adults and were found throughout the 3 years. B19V occurred mainly in 3-10 years old children and 20-29 years old adults. EV infection was most common in children up to 6 years of age and AdV was confirmed mainly in 3-6 years old children. HHV6 infection was mostly detected in 6-11 months old infants. Laboratory investigation of measles/rubella suspected cases also for B19V, EV, AdV and HHV6 allows diagnosing more than half of all cases, thus strengthening rash/fever disease surveillance in Belarus.

    The purpose of this study was to establish a new approach to improve detection of deafness due to rubella. Colombian institutes for the deaf were visited by a medical team to perform in all enrolled individuals an ophthalmological examination with emphasis in fundus eye by a retina specialist. In cases where ocular alterations compatible with CRS were found, a medical interview by a clinical geneticist analyzing pre-and postnatal history and a thorough medical examination was done. A total of 1383 deaf institutionalized individuals were evaluated in 9 Colombian cities in the period of 2005 to 2006, finding a total of 463 positive cases for salt-and-pepper retinopathy (33.5%), in which rubella could be the etiology of deafness. Medellin, Cartagena, Bucaramanga and Barranquilla were the cities with the highest percentage of Congenital rubella, corresponding to 22.8% of analyzed population. The analysis performed on cases in which reliable prenatal history was obtained in a second appointment (n=88) showed association between positive viral symptoms during pregnancy and salt-and-pepper retinopathy in 62.5% of cases, while both (retinopathy and viral symptoms) were absent in 29.5% of cases; showing a correlation in 92% of cases. The frequency of deafness by rubella obtained by this study is significantly high compared with previous Colombian studies and with international reports. It was possible to correlate the antecedent of symptoms during pregnancy with the presence of salt-and-pepper retinopathy in this deaf population when reliable prenatal history was available, therefore eye testing with emphasis in fundus examination is a good indicator of rubella induced deafness. We propose a new approach in the search of deafness causes, based on a thorough ophthalmologic examination in all deaf people. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    2013-12-01

    Full Text Available BACKGROUND: According to a report from WHO, cases of rubella infection in Indonesia has increased up to 10-fold from 2007 to 2011. Despite no data of congenital rubella syndrome in the report, there are approximately 45,000 cases of babies born with heart failure and 0.1-0.3% live births with congenital deafness in Indonesia. Allegedly, rubella infection during pregnancy may play a role in this condition. This study aimed to optimize and validate a real-time reverse transcriptase polymerase chain reaction (RT-qPCR method to detect rubella virus RNA as an aid for the diagnosis of congenital rubella infection. METHODS: Method optimization was conducted using nucleic acids extracted from Trimovax Merieux vaccine with the High Pure Viral Nucleic Acid Kit. One step RT-qPCR was performed with Quantifast Multiplex RTPCR+R Kit. Target synthetic DNA was designed and used to determine the sensitivity of the method. RNA internal control was synthesized to control the process of extraction and amplification. RESULTS: The analytical sensitivity of this method was as low as 5 copies target synthetic DNA/μl. The mean Coefficient of Variation (CV % of the critical threshold (Ct obtained were 2.71%, 1.20%, 1.62%, and 1.59% for within run, between run, between kit lots, and between operators, respectively. Recovery of the target synthetic DNA from amniotic fluid was 100.51% (by the log copies/μl at the concentration of 1,000,000 copies/μl. CONCLUSIONS: RT-qPCR is successfully used for the detection of rubella virus RNA in vaccine and synthetic nucleic acid. With its high sensitivity, good precision and recovery, this method offers a means to improve the diagnosis of congenital rubella infection in developing countries like Indonesia. KEYWORDS: congenital rubella, RT-qPCR, prenatal diagnosis, amniotic fluid.

    Because of a temporal correlation between the first notable signs and symptoms of autism and the routine childhood vaccination schedule, many parents have become increasingly concerned regarding the possible etiologic role vaccines may play in the development of autism. In particular, some have suggested an association between the Measles-Mumps-Rubella vaccine and autism. Our literature review found very few studies supporting this theory, with the overwhelming majority showing no causal association between the Measles-Mumps-Rubella vaccine and autism. The vaccine preservative thimerosal has alternatively been hypothesized to have a possible causal role in autism. Again, no convincing evidence was found to support this claim, nor for the use of chelation therapy in autism. With decreasing uptake of immunizations in children and the inevitable occurrence of measles outbreaks, it is important that clinicians be aware of the literature concerning vaccinations and autism so that they may have informed discussions with parents and caregivers.

    Full Text Available The Simple Epidemic Model uses three states to describe the spread of an infection: the susceptible (S, the infected (I, and the recovered (R. This model follows the trend of an infection over time and can predict whether an infection will spread. Using this model, epidemiologists may calculate the percentage of the population that needs to be vaccinated in order to provide a population immunity from a disease. This study will compare the vaccination percentage required for herd immunity to measles, mumps, and rubella against the current percentage of vaccinated individuals.

    Children aged 11 to vaccine (LAIV) or placebo, 35+/-7 days apart. Dose 1 was administered concomitantly with a combined measles, mumps, and rubella vaccine (Priorix). Seroresponses to measles and mumps were similar between groups. Compared with placebo, response rates to rubella in LAIV+Priorix recipients were statistically lower at a 15 IU/mL threshold (83.9% vs 78.0%) and the prespecified noninferiority criteria were not met. In a post hoc analysis using an alternate widely accepted threshold of 10 IU/mL, the noninferiority criteria were met (93.4% vs 89.8%). Concomitant administration with Priorix did not affect the overall influenza protection rate of LAIV (78.4% and 63.8% against antigenically similar influenza strains and any strain, respectively).

    Full Text Available Introduction: During May 2012, a rubella outbreak was declared in Solomon Islands. A suspected case of congenital rubella syndrome (CRS was reported from one hospital 11 months later in 2013. This report describes the subsequent CRS investigation, findings and measures implemented. Methods: Prospective CRS surveillance was conducted at the newborn nursery, paediatric and post-natal wards, and the paediatric cardiology and ophthalmology clinics of the study hospital from April to July 2013. Retrospective case finding by reviewing medical records was also undertaken to identify additional cases born between January and March 2013 for the same wards and clinics. Cases were identified using established World Health Organization case definitions for CRS. Results: A total of 13 CRS cases were identified, including two laboratory-confirmed, four clinically confirmed and seven suspected cases. Five CRS cases were retrospectively identified, including four suspected and one clinically confirmed case. There was no geospatial clustering of residences. The mothers of the cases were aged between 20 and 36 years. Three of the six mothers available for interview recalled an acute illness with rash during the first trimester of pregnancy. Discussion: Additional CRS cases not captured in this investigation are likely. Caring for CRS cases is a challenge in resource-poor settings. Rubella vaccination is safe and effective and can prevent the serious consequences of CRS. Well-planned and funded vaccination activities can prevent future CRS cases.

    Full Text Available The dyad comprising eye anomalies and congenital heart defects in the same newborn has been proposed as the best sentinel phenotype for the early detection of rubella embryopathy. Time-space birth prevalence distributions of the eye-heart dyad were described in 36 Brazilian hospitals from the Latin-American Collaborative Study of Congenital Anomalies - ECLAMC network, for the period 1994-2008. Seventy dyad cases observed among 554,531 births showed seasonal variation (Χ2 = 5.84; p < 0.05, suggesting an environmental etiology, with an increase in cases in October-March and acrophase in December. The secular distribution of dyad prevalence rates was consistent with the distribution of rubella cases in Brazil, showing a decrease from 1994 to 2004, followed by an increase until 2008. Two geographic clusters were identified, one with high and the other with low dyad prevalence. In the high prevalence cluster, a secular increase was observed, starting in 1999, matching the rubella epidemic waves observed in Brazil in 1998-2000 and 2006.

    Full Text Available BACKGROUND: Congenital rubella syndrome (CRS is the second leading cause of non‐ traumatic childhood cataracts in India. While nuclear cataract is the most common abnormality reported in CRS, congenital glaucoma is a rarer manifestation. CASE REPORT: A 34weeks low birth weight, male neonate was born by vaginal delivery with normal APGARS. The neonate had sparse hypo pigmented hair over the scalp, along with hypopigmented eye brows and eye lashes. There were erythematous lesions over palms, soles and groin region. Eye examination revealed bilateral nuclear cataracts along with buphthalmos. The neonate also had clinical manifestations of PDA, which was confirmed by 2-D Echo. Systemic involvement was seen as hepatosplenomegaly and bilateral cryptorchidism. Hence CRS was suspected and further evaluation was done. There was thrombocytopenia, mild unconjugated hyperbilirubinemia with elevated transaminases. Neurosonogram was normal and there were no intra cranial calcifications. TORCH profile in both mother and baby showed elevated rubella IgM levels confirming CRS. The neonate received supportive and symptomatic treatment. DISCUSSION: congenital nuclear cataracts are reported in 60-80% of CRS, while buphthalmos is rarely seen, more so in neonatal period. PDA occurs in 50% of CRS and two-thirds have hepatosplenomegaly. Rubelliform rash is infrequent in neonates with CRS. CONCLUSION: We report a preterm low birth weight, male neonate with congenital rubella syndrome and its rare manifestations

    Congenital rubella infection has been associated with a number of abnormalities including cardiac, central nervous system and placental complications. We present a case with multiple fetal abnormalities detected on prenatal ultrasound, and confirmed postnatally, that included a single umbilical artery, severe tricuspid regurgitation, micrognathia and agenesis of the inferior cerebellar vermis. Postnatal echocardiography additionally revealed unobstructed total anomalous pulmonary venous drainage (TAPVD) into the coronary sinus. Placental examination showed signs of placentitis, and polymerase chain reaction on neonatal serum was positive for rubella. Following a multidisciplinary team review, it was decided to provide only supportive care, and the infant died at 6 months of age owing to a respiratory tract infection. To our knowledge, TAPVD and agenesis of the inferior cerebellar vermis have not been reported previously in association with congenital rubella infection. This case illustrates how congenital infection may present in atypical ways and stresses the importance of considering congenital infection in the differential diagnosis of fetal anomalies when multiple features are present.

    Rubella virus (RV) infection is an unresolved clinical complication that affects children in developing countries including Vietnam. RV infection during the first trimester of pregnancy causes severe birth defects known as congenital rubella syndrome. This study reports on the genomic characterization of RV strains circulating in northern Vietnam during 2011-2013. RV-IgM positive amniotic fluid specimens were collected from 38 women from northern Vietnam who presented with clinical rubella at the National Hospital of Obstetrics and Gynecology in Hanoi, Vietnam. The RV genes were determined by nested PCR with primers amplifying the 739-nucleotide coding region of the E1 gene. The sequences from the amplified DNA fragments were phylogenetically analyzed and compared to reference RV strains. Seventeen out of 38 samples are positive for RV detecting. All new RV isolates are clustered to genotype 2B. Eighteen amino acid mutations were found in the T and B cell epitopes. These results suggest that genotype 2B RV strains frequently circulate in northern Vietnam. These data describe the RV genotype in Vietnam with the aim of improving maternal and child health in this country.

    Full Text Available Abstract Background The aims of this study were to assess the seroprevalence of vaccine-preventable infections in Emirati medical students, and to provide scientific evidence for implementation of a cost-effective immunization guideline and policy for medical school admission. Methods This prospective cohort study involved 261 (61% female Emirati medical students (preclinical and clinical attending the College of Medicine and Health Sciences at UAE University. Data on vaccination and history of infectious diseases were collected from participants. Blood samples were collected between July 1, 2011 and May 30, 2012 for serological testing and QuantiFERON®-TB assay. Results All students tested negative for infection with hepatitis C virus and human immunodeficiency virus. The prevalence of seropositivity to rubella virus was 97%, varicella–zoster virus 88%, mumps virus 84%, measles virus 54%, hepatitis B virus (HBV 48%, and hepatitis A virus 21%. The QuantiFERON®-TB test was positive in 8% and indeterminate in 2%. Forty percent of students received HBV vaccine at birth; their HBV titers (mean ± SD were 17.2 ± 62.9 mIU/mL (median = 1.64. The remaining 60% received it at school and their titers were 293.4 ± 371.0 mIU/mL (median = 107.7, p = 0.000. Conclusion About 50% of students were susceptible to HBV and measles virus; therefore, pre-matriculation screening for antibodies against these viruses is highly recommended. Moreover, tuberculosis screening is necessary because of the high influx of expatriates from endemic areas. Students with inadequate protection should be reimmunized prior to contact with patients.

    Flowering plants often prevent selfing through mechanisms of self-incompatibility (S.I.). The loss of S.I. has occurred many times independently, because it provides short-term advantages in situations where pollinators or mates are rare. The genus Capsella, which is closely related to Arabidopsis, contains a pair of closely related diploid species, the self-incompatible Capsella grandiflora and the self-compatible Capsella rubella. To elucidate the transition to selfing and its relationship to speciation of C. rubella, we have made use of comparative sequence information. Our analyses indicate that C. rubella separated from C. grandiflora recently ( approximately 30,000-50,000 years ago) and that breakdown of S.I. occurred at approximately the same time. Contrasting the nucleotide diversity patterns of the 2 species, we found that C. rubella has only 1 or 2 alleles at most loci, suggesting that it originated through an extreme population bottleneck. Our data are consistent with diploid speciation by a single, selfing individual, most likely living in Greece. The new species subsequently colonized the Mediterranean by Northern and Southern routes, at a time that also saw the spread of agriculture. The presence of phenotypic diversity within modern C. rubella suggests that this species will be an interesting model to understand divergence and adaptation, starting from very limited standing genetic variation.

  6. Impact of population size on incidence of rubella and measles in comparison with that of other infectious diseases.

    Yoshikura, Hiroshi

    2014-01-01

    A strong dependency of rubella and measles epidemics on population size was confirmed by 2 types of plots: the cumulative frequency distribution of number of cases per prefecture and the slope of the log-log plots of number of cases per prefecture on the y-axis vs. prefecture population size on the x-axis. These parameters were found to be constant and unique to each infectious agent. The broader cumulative frequency distribution and steeper slope of the log-log plots were characteristic to measles and rubella, i.e., a higher population size was correlated with a disproportionate high incidence of measles and rubella. No such tendency was found in other infections with possible exceptions of pertussis and keratoconjunctivitis. The dependency of rubella and measles on population density was examined by log-log plots of patient number/population vs. population density, which revealed strong population density dependency of rubella; the dependency of measles on population density was equivocal.

    2012-01-01

    Full Text Available Introduction: Rubella is a common cause of rash and fever during childhood. However, its public health importance relates to the teratogenic effects of primary rubella infection occurring in pregnant women, which can lead to fetal death with spontaneous abortion or to congenital defects in surviving infants. Most of the cases are asymptomatic and difficult to diagnose on clinical grounds. Materials and Methods: Detection of specific IgM antibodies by enzyme linked immunosorbent assay (ELISA technique is a useful method for diagnosis. This study was conducted on 180 pregnant women attending antenatal clinics at Govt. Maternity Hospital, Tirupati. All the serum samples were tested for rubella-specific IgM antibodies. Results: A seropositivity of 12.67% was observed among cases with bad obstetric history and 6.67% in normal pregnant women. Within the test group, high seropositivity (13.33% was observed in women with repeated abortions followed by in cases of intrauterine death (12.73%. Conclusions: The results indicate high prevalence of rubella in our population. All antenatal cases should be routinely screened for rubella, so that early diagnosis will help in proper management and fetal outcome.

    The present study was performed to determine whether acetaminophen (paracetamol) use after the measles-mumps-rubella vaccination could be associated with autistic disorder. This case-control study used the results of an online parental survey conducted from 16 July 2005 to 30 January 2006, consisting of 83 children with autistic disorder and 80 control children. Acetaminophen use after measles-mumps-rubella vaccination was significantly associated with autistic disorder when considering children 5 years of age or less (OR 6.11, 95% CI 1.42-26.3), after limiting cases to children with regression in development (OR 3.97, 95% CI 1.11-14.3), and when considering only children who had post-vaccination sequelae (OR 8.23, 95% CI 1.56-43.3), adjusting for age, gender, mother's ethnicity, and the presence of illness concurrent with measles-mumps-rubella vaccination. Ibuprofen use after measles-mumps-rubella vaccination was not associated with autistic disorder. This preliminary study found that acetaminophen use after measles-mumps-rubella vaccination was associated with autistic disorder.

Most of measles and rubella cases occurred in May and June, there were 89 cases of measles and 25 cases of rubella, which accounted for 65.93% and 83.33% respectively. The incidence of measles in children under one year of age was the highest (69 cases, 51.11% ). [ Conclusion ] Children under 4 years of age are the high-risk population of measles, and the prevalence rate of infants under one year of age is the highest, which indicates the protective effect from maternal antibody is insufficient. There are some rubella cases among measles suspected cases. The detection of IgM antibody is helpful to

    Many genes implicated in schizophrenia can be related to glutamatergic transmission and neuroplasticity, oligodendrocyte function, and other families clearly related to neurobiology and schizophrenia phenotypes. Others appear rather to be involved in the life cycles of the pathogens implicated in the disease. For example, aspartylglucosaminidase (AGA), PLA2, SIAT8B, GALNT7, or B3GAT1 metabolize chemical ligands to which the influenza virus, herpes simplex, cytomegalovirus (CMV), rubella, or Toxoplasma gondii bind. The epidermal growth factor receptor (EGR/EGFR) is used by the CMV to gain entry to cells, and a CMV gene codes for an interleukin (IL-10) mimic that binds the host cognate receptor, IL10R. The fibroblast growth factor receptor (FGFR1) is used by herpes simplex. KPNA3 and RANBP5 control the nuclear import of the influenza virus. Disrupted in schizophrenia 1 (DISC1) controls the microtubule network that is used by viruses as a route to the nucleus, while DTNBP1, MUTED, and BLOC1S3 regulate endosomal to lysosomal routing that is also important in viral traffic. Neuregulin 1 activates ERBB receptors releasing a factor, EBP1, known to inhibit the influenza virus transcriptase. Other viral or bacterial components bind to genes or proteins encoded by CALR, FEZ1, FYN, HSPA1B, IL2, HTR2A, KPNA3, MED12, MED15, MICB, NQO2, PAX6, PIK3C3, RANBP5, or TP53, while the cerebral infectivity of the herpes simplex virus is modified by Apolipoprotein E (APOE). Genes encoding for proteins related to the innate immune response, including cytokine related (CCR5, CSF2RA, CSF2RB, IL1B, IL1RN, IL2, IL3, IL3RA, IL4, IL10, IL10RA, IL18RAP, lymphotoxin-alpha, tumor necrosis factor alpha [TNF]), human leukocyte antigen (HLA) antigens (HLA-A10, HLA-B, HLA-DRB1), and genes involved in antigen processing (angiotensin-converting enzyme and tripeptidyl peptidase 2) are all concerned with defense against invading pathogens. Human microRNAs (Hsa-mir-198 and Hsa-mir-206) are predicted to bind

    Background: The World health organization advocates assessment of the burden of rubella and congenital rubella syndrome (CRS) by seroepidemiological surveys and surveillance programs in all countries without vaccination programs. Due to scarcity of data in developing countries, this study was conducted to assess the seromakers for natural rubella infection in Tanzania during prevaccination era so as to ascertain the gaps for future research and prevention strategies. Methods: A cross-sectional study was conducted between September and October 2014. Indirect enzyme-linked immunosorbent assay was used to detect rubella IgG and IgM antibodies. STATA version 11 was used to perform data analysis. Results: Of 723 enrolled participants, 368 (50.8%) and 94 (13%) were positive for specific IgG and IgM rubella antibodies, respectively. On multivariable logistic regression analysis, significant determinants of rubella IgG seropositivity were increase in age (odds ratios [OR]: 1.24, 95% confidence interval [CI]: 1.18–1.29, P < 0.001), low socioeconomic status (SES) (OR: 2.38, 95% CI: 1.1.23–4.50, P = 0.010), and absence of rash (OR: 4.34, 95% CI: 1.1.17–15.3, P = 0.027), while only the presence of rashes was significant determinant of rubella IgM seropositivity (OR: 2.5, 95%; 1.07–5.98, P = 0.034). Significantly higher mean IgG titers were observed in population ≥10 years (P < 0.001), those residing in urban and peri-urban areas (P < 0.001), those from employed mothers (P = 0.018), and those with no current history of fever (P = 0.018). Conclusions: The prevalence of specific rubella IgG antibodies in Tanzania is high and is associated with increase in age, absence of rash, and low SES. Results suggest a need to reconsider upper age limit for vaccination campaigns in developing countries. Screening and vaccinating women may be cost-effective campaign to prevent CRS in developing countries. PMID:28217265

    Opsoclonus-myoclonus-ataxia (OMS) is a rare clinical syndrome, of paraneoplastic infectious, post-infectious, post-vaccinal or idiopathic origin. We report a 24-year-old young man who presented with gait disorder preceded by a febrile rash and retroauricular lymph nodes. Three days before admission, he had headache, vertigo, nausea and vomiting followed by gait unsteadiness and movement disorders of limbs and eyes. On examination, he had OMS syndrome. Brain MRI, total body scan, MIBG scintigraphy, tumor markers and onconeural antibodies were normal. Cerebro-spinal fluid (CSF) analysis showed lymphocytic meningitis. Positive serum and CSF immunoglobulin M antibody against rubella virus was demonstrated. He received acyclovir with full recovery within two weeks. We discuss the peculiarities of this association with a literature review. This observation enlarges the spectrum of neurological manifestations of rubella as well as that of OMS etiologies.

  16. Treating dynamical stability as an observable: a 5:2 MMR configuration for the extrasolar system HD 181433

    Campanella, Giammarco

    2011-01-01

    The three-planet extrasolar system of HD 181433 has been detected with HARPS. The best-fit solution, announced by the discovery team, describes a highly unstable, self-disrupting configuration. In fact, a narrow observational window, only partially covering the longest orbital period, can lead to solutions representing unrealistic scenarios. Taking into account the dynamical stability as an additional observable while interpreting the RV data, we can analyse the phase space in a neighbourhood of the statistically best-fit and derive dynamically stable configurations that reproduce the observed RV signal. Our Newtonian stable best-fit model is capable of surviving for at least 250 Myrs. The two giant companions are found to be locked in the 5:2 MMR as Jupiter and Saturn in the Solar System. This mechanism does not allow close encounters even in case of highly eccentric orbits. Moreover, planets c and d are located in regions spanned by many other strong low-order MMRs. We study the dynamics of some plausible s...

    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.

    The seroprevalence (SP) of measles and rubella virus antibodies is presented by age groups obtained in the IV Serosurvey of the Region of Madrid (2008-2009). The target population is composed of residents with ages ranging between 2 and 60 years in the Region of Madrid. A two-stage cluster sample is used. The SP of measles virus antibodies is 97.8% (CI 95%: 97.3-98.2). The highest SP is observed in the 2-5 year and 41-60 year age groups. The point estimate does not reach 95% in the 16-20 and 21-30 year age groups. The SP of rubella virus antibodies is 97.2% (CI 95%: 96.5-97.7). The SP is over 95% in all of the age groups. In immigrant women between the ages of 16 and 49, the SP is 95.9% (CI 95%: 93.7-97.4). The identification of groups susceptible to the measles virus in young adults could lead to outbreaks as a result of importing the virus. The circulation of the rubella virus is possible among immigrant women aged between 16 and 49 years, which could lead to the appearance of SRC cases. Epidemiological surveillance will allow the impact on the measles and rubella elimination plan to be determined in the future.

    Full Text Available Objective: In this study, we aim to evaluate the retrospective IgG avidity index (AI test results of the pregnant, who have applied to our hospital and had pregnancy screening test and have been asked for rubella and cytomegalovirus antibody tests and IgG AI test in 4 year period. Methods: Anti-rubella IgM, anti-rubella IgG, anti-CMV IgM and anti-CMV antibodies were performed by IMMULITE 2000XPi™ Immunoassay System (Siemens, Germany whereas IgG AI tests were performed by commercial kits of rubella and cytomegalovirus antibody tests (Dia.Pro® Diagnostic, Milano-Italy. Results: Between January 2010 and December 2013, 23 (7.32 % of 314 pregnant women tested rubella IgG AI had low AI, and 266 cases had high AI rate; 14 (17.28% of 81 pregnant women tested CMV IgG AI, had lower AI rate, 52 of them had high AI. 9 out of 23 pregnant women, who were detected low rubella were requested only AI without any IgM and IgG value; the IgG antibody of 13 pregnant was reactive, and IgM antibody was not requested; IgG and IgM antibody of 1 pregnant was detected positive. When 5 pregnant, who were detected low CMV AI were requested AI without IgG and IgM value; the IgG and IgM of 4 was reactive; 4 of them had IgG reactive but IgM negative; 1 had IgG and IgM negative. Conclusion: As a result, our low rubella AI rate has been detected lower than the rates in our country since our study population contains only the pregnant. Our low CMV AI rate varies due to the same reasons as literature data. During pregnancy scanning, performing of AI testing together with specific IgG and IgM will save both time and will be more meaningful in clinical evaluation for pregnant women.

    Human Parvovirus B19 (B19V) is a prototype of the Erythroparvovirus genus in Parvoviridae family. B19V infections are often associated with fever and rash, and can be mistakenly reported as measles or rubella. Differential diagnosis of B19V illness is necessary for case management and also for public health control activities, particularly in outbreak situations in which measles or rubella is suspected. To investigate the causative role of B19V infection in children with measles- and rubella-like illness, a total of 583 sera from children with exanthema were tested for presence of B19V by determining anti-B19V IgG and IgM antibodies by ELISA as well as B19V DNA detection by nested PCR. DNA positive samples were assessed further for determination of viral load and sequence analysis by Real-Time PCR and Sanger sequencing method, respectively. Out of 583 patients, 112 (19.21%) patients were positive for B19V-IgM antibody, 110 (18.87%) were positive for B19V-IgG antibody, and 63 (10.81%) were positive for B19V viral DNA. The frequency of B19V-IgG antibodies were increased with age; that is children under 6 year old showed 7.11% seroprevalence for B19V-IgG as compared to 18.39% and 28.91% for age groups 6 to >11 and 11-14 years old, respectively. Phylogenetic analysis of the NS1-VPu1 overlapping region revealed that all sequenced B19V-DNA belonged to genotype 1. The results of this study may aid the surveillance programs aiming at eradicating measles/rubella virus in Iran, as infections with B19V can be mistakenly reported as measles or rubella if laboratory testing is not conducted.

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

    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.

    2011-01-01

    Summary The long-term antibody responses to re-immunization in recipients of allogeneic haematopoietic stem cell transplantation (allo-HSCT) have not been well studied. We prospectively and longitudinally evaluated the antibody responses to 8 vaccine antigens (diphtheria, tetanus, pertussis, measles, mumps, rubella, hepatitis B, and poliovirus) and assessed the factors associated with negative titres in 210 allo-HSCT recipients at St. Jude Children’s Research Hospital. Antibody responses lasting for more than 5 years after immunization were observed in most patients for tetanus (95.7%), rubella (92.3%), poliovirus (97.9%), and, in diphtheria-tetanus-acellular pertussis (DTaP) recipients, diphtheria (100%). However, responses to pertussis (25.0%), measles (66.7%), mumps (61.5%), hepatitis B (72.9%), and diphtheria in tetanus-diphtheria (Td) recipients (48.6%) were less favourable, with either only transient antibody responses or persistently negative titres. Factors associated with vaccine failure were older age at immunization; lower CD3, CD4 or CD19 counts; higher IgM concentrations; positive recipient cytomegalovirus serology; negative titres before immunization; acute or chronic graft-versus-host disease; and radiation during preconditioning. These response patterns and clinical factors can be used to formulate re-immunization and monitoring strategies. Patients at risk for vaccine failure should have long-term follow-up; those with loss of antibody response or no seroconversion should receive booster immunizations. PMID:22017512

    Background Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are immunotoxic in laboratory studies. Humans studies of immune effects are inconsistent. Using the U.S. National Health and Nutrition Examination Survey (NHANES) we examined PFAS serum concentration and indicators of prevalent immune function among 12 to 19 year old children. Methods In this cross-sectional study we examined PFAS serum concentration in relation to measles, mumps, and rubella antibody concentrations in NHANES 1999 – 2000 and 2003 – 2004 (n=1,191) and to allergic conditions and allergic sensitization in NHANES 2005 – 2006 (n=640). Results In adjusted, survey-weighted models, a doubling of perfluorooctane sulfonate (PFOS) concentration among seropositive children was associated with a 13.3% (95% CI −19.9, −6.2) decrease in rubella antibody concentration and a 5.9% decrease in mumps antibody concentration (95% CI −9.9, −1.6). We observed no adverse association between exposure and current allergic conditions, including asthma. Children with higher PFOS concentration were less likely to be sensitized to any allergen (OR 0.74, 95% CI 0.58, 0.95). Conclusion Increased exposure to several PFAS was associated with lower levels to mumps and rubella antibody concentrations, especially among seropositive individuals. These lower antibody concentrations may indicate a less robust response to vaccination or greater waning of vaccine-derived immunity over time. PMID:26492286

    In Canada's judicial system there are more than 31,700 youths admitted to correctional services each year. Given the prevalence of documented medical problems and high-risk behavior in this population, it is important to assess the immunization status of adolescents admitted to juvenile detention facilities. We completed a chart review of all youth admitted to an adolescent custody facility in Kingston, Ontario, between January 2003 and October 2005. There were 234 admissions, representing a total of 148 youths between the ages of 12 and 17 years. Of the youths, 73% had incomplete immunizations according to National Advisory Committee on Immunizations. In all, 49% (73 of 148) were missing tetanus, diphtheria, and acellular pertussis immunizations; 33% (49 of 148), meningococcus; 2% (four of 148), measles, mumps, and rubella; and 37% (55 of 148), hepatitis B. Successful immunization delivery within the detention facility increased complete immunization rates from 27% to 65%. This study shows the prevalence of incomplete immunizations in this population of adolescents. Given this data, there should be a greater focus on obtaining immunization records and on consistently delivering immunizations.

This study compared the sensitivity, specificity and reproducibility of two new, fully automated Elecsys(®) Rubella IgM and IgG immunoassays designed for the Elecsys 2010, Modular Analytics E170, COBAS e-411 and COBAS e-601 and e602 analytical platforms, with current assays using serum from patients with primary rubella infections, vaccinated patients, patients with potentially cross-reacting infections and on routine samples in clinical laboratories in France, Germany and Italy. Both assays showed good within-run and within-laboratory precision. A sensitivity of 79.8-96.0% was demonstrated for Elecsys IgM in primary, early acute infection, consistent with existing assays. In samples obtained from routine antenatal screening, the Elecsys Rubella IgM assay revealed high specificity (98.7-99.0%). A significantly (prubella infection was excluded, and the incidence of false positives in patients with potentially cross-reacting infections was lower with Elecsys Rubella IgM compared with other. The Elecsys Rubella IgG assay exhibited a relative sensitivity of 99.9-100.0% and specificity of 97.4-100.0% in samples from routine antenatal screening. The Elecsys Rubella IgM and IgG assays allow convenient, rapid and reliable determination of anti-rubella antibodies. Sensitivity, specificity and reproducibility were comparable with existing assay systems. Assay results were available in approximately half the time required for currently employed methods and the assays are compatible with widely used analytical platforms.

    Interpretation: Our study based on the pathological examination demonstrated that the rubella virus infection occurred via systemic organs of human fetuses. This fact was confirmed by immunohistochemistry and direct detection of viral RNA in multiple organs. To the best of our knowledge, this study is the first report demonstrating that the rubella virus infection occurred via systemic organs of the human body. Importantly, virus infection of the ciliary body could play an important role in cataractogenesis.

    Certain commercial preparations of bovine albumin, fraction V, show inhibitory activity in the rubella hemagglutination (HA) and hemagglutination-inhibition (HI) tests. This does not appear to be due to albumin per se, but instead to a contaminant (or contaminants) with the properties of a lipoprotein. All inhibitory activity can be removed from albumin preparations by treatment with kaolin, gel filtration, or flotation ultracentrifugation. We have found that, even when there was no inhibition of HA titers, kaolin treatment of the albumins prior to their incorporation into the test diluent resulted in more clearly defined agglutination patterns. Reasons for and against including albumin in the test diluent are discussed. It is concluded that, although not essential, it is a worthwhile additive. Our data suggest, however, that each batch of albumin used for this purpose should be checked for the presence of inhibitor, and that treatment with kaolin might be considered as a routine step prior to its incorporation into the test diluent.

    We investigated the effect of multiple freeze-thaw cycles on mumps, measles, and rubella virus serum antibody levels with whole-virus immunoglobulin G enzyme-linked immunoassays. Fresh serum samples from nine healthy adult volunteers were divided into six sets of five aliquots each. Samples were taken through a total of 10 freeze-thaw cycles and stored at 4 degrees C until assayed. Each assay measurement was done in replicates of five, and the mean value was reported. After completing 10 freeze-thaw cycles, we found no clinically or statistically significant effect on measured antibody levels and found no discernible detrimental effect on the ability to measure these antibodies by enzyme-linked immunoassays.

    Full Text Available Foram dosados anticorpos inibidores da hemaglutinação para o vírus da rubéola, do sarampo e da caxumba, em amostras de soro de 166 crianças de elevado nível sócio-econômico, com idade de 6 a 12 anos, que freqüentavam, em 1969, uma escola primária na cidade de São Paulo, Brasil. A per-centagem de soros positivos foi de 49,3% para a rubéola, 88,2% para o sarampo e 79,4% para a caxumba. Através de interrogatório junto aos pais, observou-se significativa correspondência entre antecedentes clínicos positivos para sarampo e caxumba e presença de anticorpos circulantes (95,3% e 91,7%, respectivamente. 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.

    In recent years, there has been an increase in the number of cases of certain immunopreventable diseases in our country. A high proportion of these have been recorded among the young adult population. The aim of this study was to determine the seroprevalence of antibodies against immunopreventable diseases with the greatest health impacts on the young adult population (19-39 y of age) in Madrid. We collected a total of 1,153 serum samples from healthy volunteers undergoing routine medical visits and used ELISA to determine the presence of IgG antibodies against measles, rubella, mumps, and varicella zoster, as well as Bordetella pertussis. The Pearson's χ(2) test was used to compare prevalences, the Mann-Whitney U test was used to compare means, and the Kruskal-Wallis test was applied for variables with more than 2 categories. Statistical significance was achieved with p values of<0.05. The global prevalence of antibodies was 92.1% for measles, 94.4% for rubella, 88.3% for mumps, 92.8% for varicella zoster, and 70.2% for B. pertussis. No statistically significant differences were found between genders. The prevalence of antibodies against measles was more than 95% in the group of individuals born after 1986, and the percentage of individuals susceptible to rubella was less than 5% in women born after 1986. In spite of adequate vaccination coverage, in our region, a population of young adults exists who have not achieved the objectives of the WHO for the elimination of measles and congenital rubella syndrome.

    To evaluate the economic impact of the routine US childhood immunization schedule: diphtheria and tetanus toxoids and acellular pertussis; tetanus and diphtheria toxoids; Haemophilus influenzae type b conjugate; inactivated poliovirus; measles, mumps, and rubella; hepatitis B; and varicella vaccines. Decision tree-based analysis was conducted using population-based vaccination coverage, published vaccine efficacies, historical data on disease incidence before vaccination, and disease incidence reported for 1995-2001. Costs were estimated using the direct cost and societal (direct and indirect costs) perspectives. Program costs included vaccine, administration, vaccine-associated adverse events, and parent travel and time lost. All costs were inflated to 2001 US dollars, and all costs and benefits in the future were discounted at a 3% annual rate. A hypothetical 2001 US birth cohort of 3,803,295 infants was followed up from birth through death. Net present value (net savings) and benefit-cost ratios of routine immunization. Routine childhood immunization with the 7 vaccines was cost saving from the direct cost and societal perspectives, with net savings of 9.9 billion dollars and 43.3 billion dollars, respectively. Without routine vaccination, direct and societal costs of diphtheria, tetanus, pertussis, H influenzae type b, poliomyelitis, measles, mumps, rubella, congenital rubella syndrome, hepatitis B, and varicella would be 12.3 billion dollars and 46.6 billion dollars, respectively. Direct and societal costs for the vaccination program were an estimated 2.3 billion dollars and 2.8 billion dollars, respectively. Direct and societal benefit-cost ratios for routine childhood vaccination were 5.3 and 16.5, respectively. Regardless of the perspective, the current routine childhood immunization schedule results in substantial cost savings.

    Measles, mumps and rubella are vaccine-preventable diseases; however limited epidemiological data are available from low-income or developing countries. Thus, it is important to investigate the transmission of these viruses in different geographical regions. In this context, a cell culture-based rapid and reliable immuno-colorimetric assay (ICA) was established and its utility studied. Twenty-three measles, six mumps and six rubella virus isolates and three vaccine strains were studied. Detection by ICA was compared with plaque and RT-PCR assays. In addition, ICA was used to detect viruses in throat swabs (n = 24) collected from patients with suspected measles or mumps. Similarly, ICA was used in a focus reduction neutralization test (FRNT) and the results compared with those obtained by a commercial IgG enzyme immuno assay. Measles and mumps virus were detected 2 days post-infection in Vero or Vero-human signaling lymphocytic activation molecule cells, whereas rubella virus was detected 3 days post-infection in Vero cells. The blue stained viral foci were visible by the naked eye or through a magnifying glass. In conclusion, ICA was successfully used on 35 virus isolates, three vaccine strains and clinical specimens collected from suspected cases of measles and mumps. Furthermore, an application of ICA in a neutralization test (i.e., FRNT) was documented; this may be useful for sero-epidemiological, cross-neutralization and pre/post-vaccine studies. © 2014 The Societies and Wiley Publishing Asia Pty Ltd.

    An outbreak of rubella affected 460 individuals in 2004 and 2005 in the community of Madrid, Spain. Most of the patients were nonvaccinated Latin American immigrants or Spanish males. This study presents the first data on rubella virus genotypes in Spain. Forty selected clinical samples (2 urine, 5 serum, 3 blood, 2 saliva, and 28 pharyngeal exudate samples) from 40 cases were collected. The 739-nucleotide sequence recommended by the World Health Organization obtained from viral RNA in these samples was analyzed by using the MEGA v4.0 software. Seventeen isolates were obtained from 40 clinical samples from the outbreak, including two isolated from congenital rubella syndrome cases. Only viral RNA of genotype 1j was detected in both isolates and clinical specimens. Two variations in amino acids, G253C and T394S, which are involved in neutralization epitopes arose during the outbreak, but apparently there was no positive selection of either of them. The origin of the outbreak remains unknown because of poor virologic surveillance in Latin America and the African countries neighboring Spain. On the other hand, this is the first report of this genotype in Europe. The few published sequences of genotype 1j indicate that it comes from Japan and the Philippines, but there are no epidemiological data supporting this as the origin of the Madrid outbreak.

    Full Text Available Flowering time is usually regulated by many environmental factors and endogenous signals. TGA family members are bZIP transcription factors that bind to the octopine synthase element, which has been closely linked to defense/stress responses. Most TGA factors interact with non-expressor of PR1 (NPR1 and plant defense responses are strengthened by this interaction. TGA1and TGA4factors bind to NPR1 only in salicylic acid (SA-induced leaves, suggesting that TGA4 has another function during plant development. Here, we isolated a bZIP transcription factor gene, TGA4, from Capsella rubella. TGA4transcripts were detected in most tissues, with high expression in leaves, low expression in stems and flowering buds, and undetectable in siliques. CruTGA4was over expressed in Arabidopsis thaliana wild typeCol-0 plants. Flowering time and total leaf number in the transgenic plants showed that overexpression of CruTGA4could delay flowering in A. thaliana. Our findings suggest that TGA4 may act as flowering regulator that controls plant flowering.

    Accurate data on immunization coverage levels are essential to public health program planning. Reliability of coverage estimates derived from immunization information systems (IISs) in states where immunization reporting by medical providers is not mandated by the state may be compromised by low rates of participation. To overcome this problem, data on coverage rates are often acquired through random-digit-dial telephone surveys, which require substantial time and resources. This project tested both the reliability of voluntarily reported IIS data and the feasibility of using these data to estimate regional immunization rates. We matched telephone survey records for 553 patients aged 19-35 months obtained in 2013 to 430 records in the San Diego County IIS. We assessed concordance between survey data and IIS data using κ to measure the degree of nonrandom agreement. We used multivariable logistic regression models to investigate differences among demographic variables between the 2 data sets. These models were used to construct weights that enabled us to predict immunization rates in areas where reporting is not mandated. We found moderate agreement between the telephone survey and the IIS for the diphtheria, tetanus, and acellular pertussis (κ = 0.49), pneumococcal conjugate (κ = 0.49), and Haemophilus influenzae type b (κ = 0.46) vaccines; fair agreement for the varicella (κ = 0.39), polio (κ = 0.39), and measles, mumps, and rubella (κ = 0.35) vaccines; and slight agreement for the hepatitis B vaccine (κ = 0.17). Consistency in factors predicting immunization coverage levels in a telephone survey and IIS data confirmed the feasibility of using voluntarily reported IIS data to assess immunization rates in children aged 19-35 months.

    Science.gov (United States)

    Scott, Lesley J

    2015-04-01

    In the EU, the live attenuated, tetravalent measles-mumps-rubella-varicella vaccine ProQuad is indicated for simultaneous vaccination against measles, mumps, rubella and varicella in individuals from 12 months of age using a two-dose schedule and may be used in infants from 9 months of age to conform with a national vaccination schedule, outbreak situations or travel to a region with a high prevalence of measles. Clinical data in young children indicates that vaccination with ProQuad is as immunogenic as the component vaccines, provides long-term protection against these potentially serious childhood infections and has an acceptable safety profile. Combining the viral strains of the measles-mumps-rubella vaccine M-M-RVAXPRO and the varicella vaccine Varivax in ProQuad reduces the complexity of vaccination schedules, thereby potentially improving vaccination coverage and the timeliness of vaccination.

    2000-01-01

    Full Text Available This study was designed to investigate whether saliva could be a feasible alternative to serum for the diagnosis of recent rubella infection in a clinic setting. Forty-five paired blood and saliva samples collected 1 to 29 days after onset of illness were tested for specific immunoglobulin (Ig M by antibody-capture radioimmunoassay (MACRIA. Rubella IgM was detected in all serum samples and in 38 (84.4% saliva specimens. Forty-six serum and saliva samples from other patients with rash diseases were tested by MACRIA for control purposes and two saliva specimens were reactive. The saliva test had specificity of 96%. These results indicate that salivary IgM detection may be a convenient non-invasive alternative to serum for investigation of recent rubella cases, especially for disease surveillance and control programmes.

    Background The burden of Congenital Rubella Syndrome (CRS) is typically underestimated in routine surveillance. Updated estimates are needed following the recent WHO position paper on rubella and recent GAVI initiatives, funding rubella vaccination in eligible countries. Previous estimates considered the year 1996 and only 78 (developing) countries. Methods We reviewed the literature to identify rubella seroprevalence studies conducted before countries introduced rubella-containing vaccination (RCV). These data and the estimated vaccination coverage in the routine schedule and mass campaigns were incorporated in mathematical models to estimate the CRS incidence in 1996 and 2000–2010 for each country, region and globally. Results The estimated CRS decreased in the three regions (Americas, Europe and Eastern Mediterranean) which had introduced widespread RCV by 2010, reaching <2 per 100,000 live births (the Americas and Europe) and 25 (95% CI 4–61) per 100,000 live births (the Eastern Mediterranean). The estimated incidence in 2010 ranged from 90 (95% CI: 46–195) in the Western Pacific, excluding China, to 116 (95% CI: 56–235) and 121 (95% CI: 31–238) per 100,000 live births in Africa and SE Asia respectively. Highest numbers of cases were predicted in Africa (39,000, 95% CI: 18,000–80,000) and SE Asia (49,000, 95% CI: 11,000–97,000). In 2010, 105,000 (95% CI: 54,000–158,000) CRS cases were estimated globally, compared to 119,000 (95% CI: 72,000–169,000) in 1996. Conclusions Whilst falling dramatically in the Americas, Europe and the Eastern Mediterranean after vaccination, the estimated CRS incidence remains high elsewhere. Well-conducted seroprevalence studies can help to improve the reliability of these estimates and monitor the impact of rubella vaccination. PMID:26962867

    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.

    IMPORTANCE The first dose of live attenuated measles-containing vaccines is associated with an increased risk of febrile seizures 7 to 10 days following immunization among 12- to 23-month-old children. The combination measles, mumps, rubella, and varicella vaccine is associated with a 2-fold increased risk of febrile seizures 7 to 10 days following immunization compared with the separately administered measles, mumps, and rubella and varicella vaccines. It is unknown whether the magnitude of these increased risks depends on age at immunization. OBJECTIVE To examine the potential modifying effect of age on the risk of fever and seizures following immunization with measles-containing vaccines. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study at 8 Vaccine Safety Datalink sites of a total of 840,348 children 12 to 23 months of age who had received a measles-containing vaccine from 2001 through 2011. EXPOSURES Any measles-containing vaccines and measles-containing vaccines by type. MAIN OUTCOMES AND MEASURES Fever and seizure events occurring during a 42-day postimmunization observation period. RESULTS In the analysis of any measles-containing vaccines, the increased risk of seizures during the 7- to 10-day risk interval, using the remainder of the observation period as the control interval, was significantly greater among older children (relative risk, 6.5; 95% CI, 5.3-8.1; attributable risk, 9.5 excess cases per 10,000 doses; 95% CI, 7.6-11.5) than among younger children (relative risk, 3.4; 95% CI, 3.0-3.9; attributable risk = 4.0 excess cases per 10,000 doses; 95% CI, 3.4-4.6). The relative risk of postimmunization fever was significantly greater among older children than among younger children; however, its attributable risk was not. In the analysis of vaccine type, measles, mumps, rubella, and varicella vaccine was associated with a 1.4-fold increase in the risk of fever and 2-fold increase in the risk of seizures compared with measles, mumps, and

    Full Text Available Objective: This study was carried out to clarify the potential health-risk and to determinant theprevalence of antenatal rubella infection in North-Central, Nigeria.Materials and methods: A descriptive cross-sectional survey was carried out among pregnant women toestablish the knowledge, attitude and practices with regards to antenatal rubella infection in earlypregnancy in Ilorin. A total of 92 subjects were recruited by simple random selection from the antenatalclinics of the University of Ilorin Teaching Hospital, Nigeria.Results: Results showed that congenitally defective eyes or ears were regarded as a greater burden tobear than a congenitally defective heart. Pregnant mothers are more likely to abort a congenitallydefective fetus before term. Multigravid pregnant women are more likely to have an abortion (X2 =12.48, df = 4, p = 0.014, just as married pregnant women were more likely to abort a congenitally defective fetus before term (X  2 = 23.64, df = 4, p = 0.0.Conclusion: It is a general assumption that Nigeria today is majorly rural, therefore, health educational activities for prompt antenatal reporting in sub-urban Ilorin, and Nigeria as a whole, may be a relevant intervention for pregnant women.

    In areas without newborn screening for severe combined immunodeficiency (SCID), disease-defining infections may lead to diagnosis, and in some cases, may not be identified prior to the first year of life. We describe a female infant who presented with disseminated vaccine-acquired varicella (VZV) and vaccine-acquired rubella infections at 13 months of age. Immunological evaluations demonstrated neutropenia, isolated CD4 lymphocytopenia, the presence of CD8(+) T cells, poor lymphocyte proliferation, hypergammaglobulinaemia and poor specific antibody production to VZV infection and routine immunizations. A combination of whole exome sequencing and custom-designed chromosomal microarray with exon coverage of primary immunodeficiency genes detected compound heterozygous mutations (one single nucleotide variant and one intragenic copy number variant involving one exon) within the IL7R gene. Mosaicism for wild-type allele (20-30%) was detected in pretransplant blood and buccal DNA and maternal engraftment (5-10%) demonstrated in pretransplant blood DNA. This may be responsible for the patient's unusual immunological phenotype compared to classical interleukin (IL)-7Rα deficiency. Disseminated VZV was controlled with anti-viral and immune-based therapy, and umbilical cord blood stem cell transplantation was successful. Retrospectively performed T cell receptor excision circle (TREC) analyses completed on neonatal Guthrie cards identified absent TREC. This case emphasizes the danger of live viral vaccination in severe combined immunodeficiency (SCID) patients and the importance of newborn screening to identify patients prior to high-risk exposures. It also illustrates the value of aggressive pathogen identification and treatment, the influence newborn screening can have on morbidity and mortality and the significant impact of newer genomic diagnostic tools in identifying the underlying genetic aetiology for SCID patients.

    A multi-site study of 351 children with Autism Spectrum Disorders (ASD) and 31 typically developing children used caregiver interviews to describe the children's early acquisition and loss of social-communication milestones. For the majority of children with ASD who had experienced a regression, pre-loss development was clearly atypical. Children who had lost skills also showed slightly poorer outcomes in verbal IQ and social reciprocity, a later mean age of onset of autistic symptoms, and more gastrointestinal symptoms than children with ASD and no regression. There was no evidence that onset of autistic symptoms or of regression was related to measles-mumps-rubella vaccination. The implications of these findings for the existence of a 'regressive phenotype' of ASD are discussed.

    We compared estimates of the age-specific population immunity to measles, mumps, rubella, hepatitis B and varicella zoster viruses in Victorian school children obtained by a national sero-survey, using a convenience sample of residual sera from diagnostic laboratories throughout Australia, with those from a three-stage random cluster survey. When grouped according to school age (primary or secondary school) there was no significant difference in the estimates of immunity to measles, mumps, hepatitis B or varicella. Compared with the convenience sample, the random cluster survey estimated higher immunity to rubella in samples from both primary (98.7% versus 93.6%, P = 0.002) and secondary school students (98.4% versus 93.2%, P = 0.03). Despite some limitations, this study suggests that the collection of a convenience sample of sera from diagnostic laboratories is an appropriate sampling strategy to provide population immunity data that will inform Australia's current and future immunisation policies.

    Full Text Available Aim: to study safety and immunological efficacy of vaccination against influenza in separate and associated immunization according to the National Calendar. Patients and methods: 100 children with various disorders as well as children with HIV subjected to revaccination against diphtheria, tetanus, measles, parotiditis and rubella, were included into the study. Children were divided into 5 groups of 20 persons each: groups of separate or associated vaccination. In order to assess safety of vaccination children were observed for 30 days after vaccination. In order to analyze immunologic efficacy participants were taken serum tests before and on the 30th day after vaccination. Results: the study demonstrated high safety of the vaccine against influenza. Mild and moderate topical and general reactions were observed in isolated instances and did not differ in comparison groups. Simultaneous vaccination against influenza with immunization against diphtheria, parotiditis and rubella did not influence synthesis of antibodies, while synthesis of antibodies against measles was decreased; immunization against diphtheria and measles when associated with vaccination against influenza depressed synthesis of antibodies against A/H3N2 influenza. Conclusions: vaccine against influenza has low reactivity, high safety and can be used in association with immunization according to the National calendar in independence to somatic disorders of patients.

    Full Text Available The human pathogenic fungus Candida albicans is the predominant cause of both superficial and invasive forms of candidiasis. C. albicans primarily infects immunocompromised individuals as a result of either immunodeficiency or intervention therapy, which highlights the importance of host immune defences in preventing fungal infections. The host defence system utilises a vast communication network of cells, proteins, and chemical signals distributed in blood and tissues, which constitute innate and adaptive immunity. Over the last decade the identity of many key molecules mediating host defence against C. albicans has been identified. This review will discuss how the host recognises this fungus, the events induced by fungal cells, and the host innate and adaptive immune defences that ultimately resolve C. albicans infections during health.

    We previously demonstrated that human embryonic mesenchymal cells derived from the palate (HEMP cells) retain alkaline phosphatase (ALP) content and capacity for collagen synthesis after long-term culture, and their growth is markedly stimulated by epidermal growth factor (EGF). There was a dramatic decrease in ALP content and capacity to synthesize collagen in HEMP cells (HEMP-RV cells) persistently infected with rubella virus (RV).

    Preventive immunization has provided one of the major advances in population health during the past century. However, a surprising cultural phenomenon is the emergence of concerns about immunization safety, in part due to prominently controversial biomedical studies. One ongoing theoretical safety concern is the possibility of human molecular mimicry by measles, mumps, rubella (MMR) antigens. The study of Polymeros et al. in this BMC Medicine presents a systematic evaluation and refutation of this safety concern. This provides significant new scientific evidence in support of the safety of pediatric vaccines, which will inform the ongoing policy and cultural understanding of this important public health measure.

    Full Text Available Vaccination of health care workers is an efficient way to reduce the risk of occupational infection and to prevent nosocomial transmission to vulnerable patients. Despite this, achieving high immunization rates among those professionals is a challenge. We assessed the immunization status of Residents in Pediatrics at the Federal University of São Paulo from June to December 2008. Their immunization records were checked and evaluated according to the Brazilian Immunization Schedule for health care workers. Considering all required vaccines, only 3.1% of the 64 Residents were up-to-date with their immunizations. Influenza was the vaccine with the lowest uptake (3.1% and measles and rubella were diseases with the highest evidence of immunity (62.5% each. Only 37.5% of Residents had received three hepatitis B vaccine doses with a subsequent serology confirming seroconversion. Moreover, the vast majority of Residents in Pediatrics who were not up-to-date were unaware of the fact. Both medical schools and Pediatric Residence programs should not only offer information but also check vaccination records in an effort to keep their healthcare workers´ vaccinations up-to-date.

    Full Text Available The last two decades a huge progress has taken place in the field of the primary prevention of infections and many new vaccines have been introduced in the compulsory vaccination program. There is evidence, however, that immunization coverage against some infectious diseases is not adequate. Aim: It was to investigate the level of immunization coverage of Greek and Immigrants' children aged 4-12 years old in the prefecture of Evritania regarding vaccines against pertussis-diphtheria-tetanus (DTaP, poliomyelitis (IPV and measles–mumps–rubella (MMR. Material and methods: The sample of the study consisted of the pupils of all nursing and elementary schools of the prefecture of Evritania , aged 4-12 years old. Children's personal Health Cards were used to evaluate the adequacy of vaccine doses. X2 was usedfor comparisons. Statistics was processed with SPPS 17.0. Results: The boys of the sample were 469 (51.9% and the girls 434 (48.1%. Full vaccination coverage with DTaP, MMR and IPV was 87.3%, 79.9%, and 97.6% respectively. No statistically significant differences were observed between Greek and Immigrants' children. Conclusion: Vaccination coverage against measles, mumps and rubella was inadequate. Immigrants' and Greek children are equally covered. Vaccination coverage with MMR is troublesome.

    Adina rubella Hance (AR), a plant native to Korea, has been used as traditional medicine for dysentery, eczema, intoxication, and external hemorrhages. Previous phytochemical studies of AR have reported several components, including terpenoids, phenolics, and alkaloids. The current study evaluated the anti-oxidative and anti-inflammatory activities and 5α-reductase inhibition of isolated compounds of AR leaves to find a potential therapeutic agent for benign prostatic hypertrophy (BPH). Repeated chromatographic isolation of an 80% acetone extract of AR leaves yielded seven phenolic compounds: caffeic acid (1), chlorogenic acid (2), methyl chlorogenate (3), quercetin-3-rutinoside (4), kaempferol-3-O-α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside (5), hyperoside (6), and grandifloroside (7). Compound 7 is a novel compound in AR. Caffeoyl derivatives 1-3 and 7 showed good anti-oxidative activities. In particular, caffeic acid (1) and grandifloroside (7) showed potent anti-inflammatory activities, and 7 also exhibited potent inhibitory activity against TNF-α and 5α-reductase. Our results show that the extract and grandifloroside (7) from leaves of AR might be developed as a source of potent anti-oxidative and anti-inflammatory agents and therapeutic agent for BPH.

    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.

    Metapopulation rescue effects are thought to be key to the persistence of many acute immunizing infections. Yet the enhancement of persistence through spatial coupling has not been previously quantified. Here we estimate the metapopulation rescue effects for four childhood infections using global WHO reported incidence data by comparing persistence on island countries vs all other countries, while controlling for key variables such as vaccine cover, birth rates and economic development. The relative risk of extinction on islands is significantly higher, and approximately double the risk of extinction in mainland countries. Furthermore, as may be expected, infections with longer infectious periods tend to have the strongest metapopulation rescue effects. Our results quantitate the notion that demography and local community size controls disease persistence.

    Abstract:
    Background: between May 2010 and october 2011 the unit of Preventive Medicine for the developmental ages of district IV, Health unit aSL rM/a, received 136 measles case notifications from the unit of Epidemiology and Prophylaxis of Infectious diseases.
    Methods: in accordance with the infectious diseases monitoring protocol, we introduced a series of preventive measures, such as monitoring subjects in contact with measles-infected patients, recommend- ing the administration of two Measles Mumps and rubella (MMr doses four weeks apart, and informing paediatricians, families and school teachers about the measles epidemic.
    Results: all the activities above led to an increased number of MMr doses administered and a significant improvement of measles immunization coverage among residents of the district IV health unit of rome. concerning MMr 1, in a sample cohort consisting of children ≤24 months, the immunization coverage increased from 77% on the 31/12/09 to 88% on the 31/12/11. Instead, for MMr 2, in a cohort of children ≤6 years, the same ratio improved from 51% on the 31/12/09 to 65% on the 31/12/11.
    Discussion: the results indicate a material increase in the immunization coverage once our public health actions and vaccination strategies had been implemented among young residents of district IV aSL rM/a...

    Females typically develop higher antibody responses and experience more adverse reactions following vaccination than males. These differences are observed in response to diverse vaccines, including the bacillus Calmette-Guerin vaccine, the measles, mumps and rubella vaccine, the yellow fever virus vaccine and influenza vaccines. Sex differences in the responses to vaccines are observed across diverse age groups, ranging from infants to aged individuals. Biological as well as behavioral differences between the sexes are likely to contribute to differences in the outcome of vaccination between the sexes. Immunological, hormonal, genetic and microbiota differences between males and females may also affect the outcome of vaccination. Identifying ways to reduce adverse reactions in females and increase immune responses in males will be necessary to adequately protect both sexes against infectious diseases. PMID:25573105

    This study aimed to determine if immunogenicity to measles-mumps-rubella vaccine delivered to infants via a disposable-syringe jet injector (DSJI) was non-inferior to that administered by needle and syringe (NS). Vaccination safety was evaluated, as were the use, performance, and acceptability of each delivery method. The DSJI was the PharmaJet 2009 generation-1 device (G1) and the vaccine was measles-mumps-rubella vaccine from Bio-Manguinhos. Five hundred eighty-two healthy Brazilian infants were randomized to receive vaccine via G1 or NS. Seroconversion rates against measles and mumps viruses in the G1 treatment group did not meet non-inferiority criteria when compared with the NS group; however, responses in the G1 group to rubella virus were non-inferior to those of NS vaccinees. Most adverse events were mild or moderate. Crying after injection was more frequent in the NS group, and local skin reactions were more common in the G1 group. Five serious adverse events were judged causally unrelated to treatment and all resolved. Parents/guardians expressed a strong preference for G1 over NS for their children. Vaccinators found the G1 easy to use but noted incomplete vaccine delivery in some cases. Although the G1 has been superseded by an updated device, our results are important for the continued improvement and evaluation of DSJIs, which have the potential to overcome many of the challenges and risks associated with needle-based injections worldwide. Recommendations for future DSJI clinical studies include rigorous training of vaccinators, quantitative measurement of wetness on the skin following injection, and regular monitoring of device and vaccinator performance.

    As the average life expectancy increases, retired people want to travel. Five to 8% of travellers in tropical areas are old persons. Immune system suffers of old age as the other organs. The number and the functions of the T-lymphocytes decrease, but the B-lymphocytes are not altered. So, the response to the vaccinations is slower and lower in the elderly. Influenza is a great cause of death rate in old people. The seroconversion, after vaccine, is 50% from 60 to 70 years old, 31% from 70 to 80 years old, and only 11% after 80 years old. But in public health, the vaccination reduced the morbidity by 25%, admission to hospital by 20%, pneumonia by 50%, and mortality by 70%. Antipoliomyelitis vaccine is useful for travellers, as the vaccines against hepatitis and typhoid fever. Pneumococcal vaccine is effective in 60%. Tetanus is fatal in at last 32% of the people above 80 years, therefore this vaccine is very important.

    Immunization Days (NIDs are held twice a year to maintain the elimination of poliomyelitis and to provide routine immunization for children younger than five years of age. Few studies have examined factors associated with participation in National Immunization Days among Brazilian children, or the contribution of immunization days to the coverage of recommended vaccines. METHODS: We conducted a household cluster survey in 26 state capitals and the Federal District among children aged 19 to 35 months. Vaccination histories, including dates of vaccination, participation in the most recent NID or reasons for non-participation were obtained. Survey estimates were compared with official estimates based on doses administered. RESULTS: Among the 17,749 children surveyed, 16,213 (91% participated in the most recent NID. Children who received vaccination in the private sector had the lowest participation (84% in NIDs. In 13 capitals, official coverage estimates were higher than those from the survey. The main reasons given for non-participation the most recent NID included parent's decision not to participate, doctor's advice, child's illness, and factors associated with the organization of the NID. Overall, 15% of the children surveyed had received at least one immunization in addition to oral polio vaccine in the most recent NID, including yellow fever, hepatitis B, measles-mumps-rubella (MMR and combined diphtheria-tetanus-pertussis-Haemophilus influenzae type b vaccines. CONCLUSIONS: In Brazilian capitals, National Immunization Days continue to enjoy high levels of acceptance by the population and offer opportunities to complete recommended immunization schedules. Reasons for non-participation suggest the need for different communication strategies to reach parents who do not bring their children for vaccination on NIDs.

    In 1954, the Nobel Prize for Medicine was awarded to Drs John Enders, Thomas Weller, and Frederick Robbins for their watershed discovery that growth of poliomyelitis virus occurred in cultures of cells of extraneural origin, first reported in 1949. Their demonstration in 1949 that the Lansing type II strain of poliomyelitis could be grown in cultures of human embryonic tissue set into motion a race to develop a vaccine for the disease that had crippled countless thousands of individuals. The discovery and subsequent recognition were only the beginning of a prolific career for Thomas Huckle Weller, who made numerous contributions to the field of virology, including isolating the varicella-zoster virus (VZV) from cases of chickenpox and zoster, providing suggestive evidence that the same virus is responsible for both diseases; isolating the human cytomegalovirus (CMV) for the first time in tissue culture and suggesting the descriptive name now used for it; establishing Coxsackie viruses as the cause of epidemic pleurodynia: and first isolating rubella virus, the cause of German measles. This article presents a brief biography of Dr Thomas Huckle Weller, one of the field's most important figures, with primary focuses on his work on poliomyelitis, varicella-zoster virus, rubella virus, and cytomegalovirus.

    Rubella remains a significant burden in mainland China. In this report, 667 viruses collected in 24 of 31 provinces of mainland China during 2010-2012 were sequenced and analyzed, significantly extending previous reports on limited numbers of viruses collected before 2010. Only viruses of genotypes 1E and 2B were found. Genotype 1E viruses were found in all 24 provinces. Genotype 1E viruses were likely introduced into mainland China around 1997 and endemic transmission of primarily one lineage became established. Viruses reported here from 2010-2012 are largely in a single cluster within this lineage. Genotype 2B viruses were rarely detected in China prior to 2010. This report documents a previously undetected 2B lineage, which likely became endemic in eastern provinces of China between 2010 and 2012. Bayesian analyses were performed to estimate the evolutionary rates and dates of appearance of the genotype 1E and 2B viral linages in China. A skyline plot of viral population diversity did not provide evidence of reduction of diversity as a result of vaccination, but should be useful as a baseline for such reductions as vaccination programs for rubella become widespread in mainland China.

    M-M-R™II (measles, mumps, and rubella virus vaccine live; Merck, Sharp, & Dohme Corp.) is indicated for simultaneous vaccination against measles, mumps, and rubella in individuals ≥ 12 months of age. Before the vaccine era, these viruses infected most exposed individuals, with subsequent morbidity and mortality. One of the greatest achievements of public health has been to eliminate these 3 diseases in large geographic areas. The safety profile of M-M-R™II is described using data from routine global postmarketing surveillance. Postmarketing surveillance has limitations (including incomplete reporting of case data), but allows collection of real-world information on large numbers of individuals, who may have concurrent medical problems excluding them from clinical trials. It can also identify rare adverse experiences (AEs). Over its 32-year history, ≈ 575 million doses of M-M-R™II have been distributed worldwide, with 17,536 AEs voluntarily reported for an overall rate of 30.5 AEs/1,000,000 doses distributed. This review provides evidence that the vaccine is safe and well-tolerated.

    The aim of this study was to establish and apply a real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) for rubella virus (RV) RNA. First, the primer and TaqMan probe concentrations, as well as reaction temperatures were optimized to establish an efficient real-time quantitative RT-PCR assay for RV RNA. Next, an RV-specific PCR amplicon was made as an external standard to estimate the linearity, amplification efficiency, analytical sensitivity and reproducibility of the real time quantitative assay. Finally, the assay was applied to quantify RVRNA in clinical samples for rubella diagnosis.The RV-specific PCR amplicon was prepared for evaluation of the assay at 503 bp, and its original concentration was 2.75×109 copies/μl. The real time quantitative assay was shown to have good linearity (R2=0.9920), high amplification efficiency (E=1.91), high sensitivity (275 copies/ml), and high reproducibility (variation coefficient range, from 1.25% to 3.58%). Compared with the gold standard, the specificity and sensitivity of the assay in clinical samples was 96.4% and 86.4%, respectively. Therefore, the established quantitative RT-PCR method is a simple, rapid, less-labored, quantitative, highly specific and sensitive assay for RV RNA.

    Individual immunity is a powerful force affecting host health and pathogen evolution. Importantly, the effects of individual immunity also scale up to affect pathogen transmission dynamics and the success of vaccination campaigns for entire host populations. Population-scale immunity is often termed 'herd immunity'. Here we outline how individual immunity maps to population outcomes and discuss implications for control of infectious diseases. Particular immunological characteristics may be more or less likely to result in a population level signature of herd immunity; we detail this and also discuss other population-level outcomes that might emerge from individual-level immunity.

    The Advisory Committee on Vaccines of the Spanish Association of Pediatrics (CAV-AEP) updates the immunization schedule every year, taking into account epidemiological data as well as evidence on the effectiveness and efficiency of vaccines. The present schedule includes grades of recommendation. We have graded as routine vaccinations those that the CAV-AEP believes all children should receive; as recommended those that fit the profile for universal childhood immunization and would ideally be given to all children, but that can be prioritized according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in situations of risk. Immunization schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Nevertheless, the achievement of a unified immunization schedule in all regions of Spain is a top priority for the CAV-AEP. Based on the latest epidemiological trends, the main changes introduced to the schedule are the administration of the first dose of the MMR and the varicella vaccines at age 12 months (12-15 months) and the second dose at age 2-3 years, as well as the administration of the Tdap vaccine at age 4-6 years, always followed by another dose at 11-14 years of age. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-14 years must increase. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunization schedule. Universal vaccination against varicella in the second year of life is an effective strategy and therefore a desirable objective. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. Finally, it emphasizes the need to bring incomplete vaccinations up to date following the catch

    The marker of Japanese domestic rubella vaccines is their lack of immunogenicity in guinea pigs. This has long been thought to be related to the temperature sensitivity of the viruses, but supporting evidence has not been described. In this study, we generated infectious clones of TO-336.vac, a Japanese domestic vaccine, TO-336.GMK5, the parental virus of TO-336.vac, and their mutants, and determined the molecular bases of their temperature sensitivity and immunogenicity in guinea pigs. The results revealed that Ser(1159) in the non-structural protein-coding region was responsible for the temperature sensitivity of TO-336.vac dominantly, while the structural protein-coding region affected the temperature sensitivity subordinately. The findings further suggested that the temperature sensitivity of TO-336.vac affected the antibody induction in guinea pigs after subcutaneous inoculation.

    The classical model of immunity posits that the immune system reacts to pathogens and injury and restores homeostasis. Indeed, a century of research has uncovered the means and mechanisms by which the immune system recognizes danger and regulates its own activity. However, this classical model does not fully explain complex phenomena, such as tolerance, allergy, the increased prevalence of inflammatory pathologies in industrialized nations and immunity to multiple infections. In this Essay, I propose a model of immunity that is based on equilibrium, in which the healthy immune system is always active and in a state of dynamic equilibrium between antagonistic types of response. This equilibrium is regulated both by the internal milieu and by the microbial environment. As a result, alteration of the internal milieu or microbial environment leads to immune disequilibrium, which determines tolerance, protective immunity and inflammatory pathology.

    To evaluate the effectiveness and cost effectiveness of computer-generated recall letters to parents of children overdue for immunizations. This randomized controlled trial included children of two facilities in a regional health maintenance organization. Parents of 20-month-olds who had not yet received a measles-mumps-rubella (MMR) immunization were identified via a computerized immunization tracking system. One half were mailed personalized letters that included the recommended immunization schedule and a request to call for an appointment; the other half served as a control group. Receipt of the MMR between 20 and 24 months of age was evaluated with the computerized tracking system. A telephone survey was conducted with parents whose children had not received the MMR by 24 months. Decision analysis was used to project the theoretical outcomes and costs of a recall letter policy for other populations. Among 20-month-old children 10% had not received the MMR; 289 families were included in the analysis. Of families who were mailed letters, 54% (82 of 153) received the MMR by 24 months of age, compared with 35% (47 of 136) of those in the control group (P = 0.001). The telephone survey was completed with 110 parents of children who still did not appear on the health plan computer as having received the MMR by 24 months. Fifteen percent said the child had received an immunization at an outside provider, and of the rest 62% said they had not been aware that an immunization was due. In the cost effectiveness analysis it was projected that recall letters would increase the immunization rate for the regional population of approximately 30000 children from 86% to 90% at a total cost of $5031 annually. The cost per additional child appropriately immunized was $4.04. In sensitivity analyses this cost effectiveness ratio varied depending on the baseline population coverage rate as well as the estimated effectiveness of recall letters.

  12. Autistic disorder and viral infections.

    2005-02-01

    Autistic disorder (autism) is a behaviorally defined developmental disorder with a wide range of behaviors. Although the etiology of autism is unknown, data suggest that autism results from multiple etiologies with both genetic and environmental contributions, which may explain the spectrum of behaviors seen in this disorder. One proposed etiology for autism is viral infection very early in development. The mechanism, by which viral infection may lead to autism, be it through direct infection of the central nervous system (CNS), through infection elsewhere in the body acting as a trigger for disease in the CNS, through alteration of the immune response of the mother or offspring, or through a combination of these, is not yet known. Animal models in which early viral infection results in behavioral changes later in life include the influenza virus model in pregnant mice and the Borna disease virus model in newborn Lewis rats. Many studies over the years have presented evidence both for and against the association of autism with various viral infections. The best association to date has been made between congenital rubella and autism; however, members of the herpes virus family may also have a role in autism. Recently, controversy has arisen as to the involvement of measles virus and/or the measles, mumps, rubella (MMR) vaccine in the development of autism. Biological assays lend support to the association between measles virus or MMR and autism whereas epidemiologic studies show no association between MMR and autism. Further research is needed to clarify both the mechanisms whereby viral infection early in development may lead to autism and the possible involvement of the MMR vaccine in the development of autism.

    Viruses are obligate parasites which are able to infect cells of all living organisms. Multiple antiviral defense mechanisms have appeared early in evolution of the immune system. Higher vertebrates have the most complex antiviral immunity which is based on both innate and adoptive immune responses. However, majority of living organisms, including plants and invertebrates, rely exclusively on innate immune mechanisms for protection against viral infections. There are some striking similarities in several components of the innate immune recognition between mammals, plants and insects, rendering these signaling cascades as highly conserved in the evolution of the immune system. This review summarizes recent advances in the field of innate immune recognition of viruses, with particular interest on pattern-recognition receptors.

  15. Simultaneous immunization against tuberculosis.

    Full Text Available BACKGROUND: BCG, the only licensed vaccine against tuberculosis, provides some protection against disseminated disease in infants but has little effect on prevention of adult pulmonary disease. Newer parenteral immunization prime boost regimes may provide improved protection in experimental animal models but are unproven in man so that there remains a need for new and improved immunization strategies. METHODS AND FINDINGS: Mice were immunized parenterally, intranasally or simultaneously by both routes with BCG or recombinant mycobacterial antigens plus appropriate adjuvants. They were challenged with Mycobacterium tuberculosis (Mtb and the kinetics of Mtb growth in the lungs measured. We show that simultaneous immunization (SIM of mice by the intranasal and parenteral routes is highly effective in increasing protection over parenteral BCG administration alone. Intranasal immunization induces local pulmonary immunity capable of inhibiting the growth of Mtb in the early phase (the first week of infection, while parenteral immunization has a later effect on Mtb growth. Importantly, these two effects are additive and do not depend on priming and boosting the immune response. The best SIM regimes reduce lung Mtb load by up to 2 logs more than BCG given by either route alone. CONCLUSIONS: These data establish SIM as a novel and highly effective immunization strategy for Mtb that could be carried out at a single clinic visit. The efficacy of SIM does not depend on priming and boosting an immune response, but SIM is complementary to prime boost strategies and might be combined with them.

  16. Origins of adaptive immunity.

    2011-01-01

    Adaptive immunity, involving distinctive antibody- and cell-mediated responses to specific antigens based on "memory" of previous exposure, is a hallmark of higher vertebrates. It has been argued that adaptive immunity arose rapidly, as articulated in the "big bang theory" surrounding its origins, which stresses the importance of coincident whole-genome duplications. Through a close examination of the key molecules and molecular processes underpinning adaptive immunity, this review suggests a less-extreme model, in which adaptive immunity emerged as part of longer evolutionary journey. Clearly, whole-genome duplications provided additional raw genetic materials that were vital to the emergence of adaptive immunity, but a variety of other genetic events were also required to generate some of the key molecules, whereas others were preexisting and simply co-opted into adaptive immunity.

    2017-01-01

    The human immune system is highly variable between individuals but relatively stable over time within a given person. Recent conceptual and technological advances have enabled systems immunology analyses, which reveal the composition of immune cells and proteins in populations of healthy individuals. The range of variation and some specific influences that shape an individual's immune system is now becoming clearer. Human immune systems vary as a consequence of heritable and non-heritable influences, but symbiotic and pathogenic microbes and other non-heritable influences explain most of this variation. Understanding when and how such influences shape the human immune system is key for defining metrics of immunological health and understanding the risk of immune-mediated and infectious diseases.

    Full Text Available Insect innate immunity is both a model for vertebrate immunity as well as a key system that impactsmedically important pathogens that are transmitted by insects. Recent developments in proteomics andprotein identification techniques combined with the completion of genome sequences for Anophelesgambiae and Drosophila melanogaster provided the tools for examining insect immunity at a new level ofmolecular detail. Application of proteomics to insect immunity resulted in predictions of new roles inimmunity for proteins already known in other contexts (e.g. ferritin, transferrin, Chi-lectins and helped totarget specific members of multi-gene families that respond to different pathogens (e.g. serine proteases,thioester proteins. In addition, proteomics studies verify that post-translational modifications play a keyrole in insect immunity since many of the identified proteins are modified in some way. These studiescomplement recent work on insect transcriptomes and provide new directions for further investigation ofinnate immunity.

    For millennia, humans have sought and found purpose, solace, values, understanding, and fellowship in religious practices. Buddhist nuns performed variolation against smallpox over 1000 years ago. Since Jenner developed vaccination against smallpox in 1796, some people have objected to and declined vaccination, citing various religious reasons. This paper reviews the scriptural, canonical basis for such interpretations, as well as passages that support immunization. Populous faith traditions are considered, including Hinduism, Buddhism, Jainism, Judaism, Christianity, and Islam. Subjects of concern such as blood components, pharmaceutical excipients of porcine or bovine origin, rubella strain RA 27/3, and cell-culture media with remote fetal origins are evaluated against the religious concerns identified. The review identified more than 60 reports or evaluations of vaccine-preventable infectious-disease outbreaks that occurred within religious communities or that spread from them to broader communities. In multiple cases, ostensibly religious reasons to decline immunization actually reflected concerns about vaccine safety or personal beliefs among a social network of people organized around a faith community, rather than theologically based objections per se. Themes favoring vaccine acceptance included transformation of vaccine excipients from their starting material, extensive dilution of components of concern, the medicinal purpose of immunization (in contrast to diet), and lack of alternatives. Other important features included imperatives to preserve health and duty to community (e.g., parent to child, among neighbors). Concern that 'the body is a temple not to be defiled' is contrasted with other teaching and quality-control requirements in manufacturing vaccines and immune globulins. Health professionals who counsel hesitant patients or parents can ask about the basis for concern and how the individual applies religious understanding to decision-making about

    Discrepancies often exist between recorded immunization coverage and the real immunity level in a community. To estimate the vaccination coverage against measles in south-east Islamic Republic of Iran, a crosssectional study was conducted in 3 districts during summer 2011. Using probability proportional to size cluster sampling, 1368 children aged 30-54 months were selected. Serum samples of 663 who had received 2 injections of mumpsmeasles- rubella (MMR) vaccine were checked for anti-measles IgG. Vaccination coverage for the second dose of MMR vaccine was 93.7%. The prevalence of anti-measles IgG in those who had received at least 2 MMR vaccine doses was 94.6%. There was a statistically significant association between the serological results and variables that reflected poor accessibility to health services. Combining serological results with coverage data, the proportion of the community protected against measles was estimated as 88.6%, which was below the limits defined for the measles elimination goals.

    Full Text Available Introduction: There are large Pacific island communities in western and south-western Sydney, New South Wales, Australia. In 2011 and 2012, measles outbreaks disproportionally affected children and youth within these communities. The objectives of this study were to explore barriers to immunization in a Pacific island community from the perspectives of community members and health professionals and to conduct a pilot programme whereby immunization catch-up clinics were held in a Samoan church in western Sydney. Methods: Interviews were conducted with Pacific island community members (N = 12 and health professionals connected with the Pacific island community (N = 7 in 2013. A partnership with a local Samoan church was established to provide an accessible venue for immunization catch-up clinics. Results: Among the community members there were high levels of belief in the importance of immunization and a positive view regarding the protection offered by immunization. A key barrier reported by community members was being busy and therefore having limited time to get children immunized. The important role of the church within the community was emphasized in the interviews, and as a result, two immunization catch-up clinics were held in a Samoan church in western Sydney. The age range of attendees was 7–33 years. A total of 31 measles, mumps and rubella doses and 19 meningococcal C doses were given during the two clinics. Discussion: The outcomes of the interviews and the subsequent clinics highlighted the potential of churches as a venue for providing public health interventions such as catch-up immunization.

  6. Transplantation Immunity. Contemporary Views.

    "Transplantation immunity in Cyclosporin era" is a special chapter in science under name transplantation immunity. Nowadays, practically all the organs can be grafted: kidney, heart, lung, liver, pancreas both as organ, and as islet cells, bone marrow from relative and unrelative donors. The broad spectrum of grafted organs gave one more surprising peculiarity of transplantation immunity: it operates with different strength after transplantation of various organs. If the decreasing gradient of transplantation immunity could be composed, then it appeared to be approximately in the following order: bone marrow - skin - kidney - heart - lung. The most complicated operating activity of transplantation immunity is occurring after bone marrow transplantation, especially from unrelative donor, because in bone marrow transplantation immunological process develops in both directions. Therefore now, bone marrow is the only organ (tissue), when the complete compatibility between donor and recipient is required after its transplantation; especially in cases with unrelative donors.

  7. Behavioral Immunity in Insects

    Directory of Open Access Journals (Sweden)

    Thierry Lefèvre

    2012-08-01

    Full Text Available Parasites can dramatically reduce the fitness of their hosts, and natural selection should favor defense mechanisms that can protect hosts against disease. Much work has focused on understanding genetic and physiological immunity against parasites, but hosts can also use behaviors to avoid infection, reduce parasite growth or alleviate disease symptoms. It is increasingly recognized that such behaviors are common in insects, providing strong protection against parasites and parasitoids. We review the current evidence for behavioral immunity in insects, present a framework for investigating such behavior, and emphasize that behavioral immunity may act through indirect rather than direct fitness benefits. We also discuss the implications for host-parasite co-evolution, local adaptation, and the evolution of non-behavioral physiological immune systems. Finally, we argue that the study of behavioral immunity in insects has much to offer for investigations in vertebrates, in which this topic has traditionally been studied.

    2014-11-06

    Life-threatening fungal infections have risen sharply in recent years, owing to the advances and intensity of medical care that may blunt immunity in patients. This emerging crisis has created the growing need to clarify immune defense mechanisms against fungi with the ultimate goal of therapeutic intervention. We describe recent insights in understanding the mammalian immune defenses that are deployed against pathogenic fungi. We focus on adaptive immunity to the major medically important fungi and emphasize three elements that coordinate the response: (1) dendritic cells and subsets that are mobilized against fungi in various anatomical compartments; (2) fungal molecular patterns and their corresponding receptors that signal responses and shape the differentiation of T-cell subsets and B cells; and, ultimately (3) the effector and regulatory mechanisms that eliminate these invaders while constraining collateral damage to vital tissue. These insights create a foundation for the development of new, immune-based strategies for prevention or enhanced clearance of systemic fungal diseases.

    2016-02-01

    Cytokines are a large and diverse group of small proteins that can affect many biological processes, but most commonly cytokines are known as mediators of the immune response. In the event of an infection, cytokines are produced in response to an immune stimulus, and they function as key regulators of the immune response. Cytokines come in many shapes and sizes, and although they vary greatly in structure, their functions have been well conserved in evolution. The immune signaling pathways that respond to cytokines are remarkably conserved from fly to man. Therefore, Drosophila melanogaster, provides an excellent platform for studying the biology and function of cytokines. In this review, we will describe the cytokines and cytokine-like molecules found in the fly and discuss their roles in host immunity.

    2010-01-01

    The human immune system has numerous properties that make it ripe for exploitation in the computational domain, such as robustness and fault tolerance, and many different algorithms, collectively termed Artificial Immune Systems (AIS), have been inspired by it. Two generations of AIS are currently in use, with the first generation relying on simplified immune models and the second generation utilising interdisciplinary collaboration to develop a deeper understanding of the immune system and hence produce more complex models. Both generations of algorithms have been successfully applied to a variety of problems, including anomaly detection, pattern recognition, optimisation and robotics. In this chapter an overview of AIS is presented, its evolution is discussed, and it is shown that the diversification of the field is linked to the diversity of the immune system itself, leading to a number of algorithms as opposed to one archetypal system. Two case studies are also presented to help provide insight into the m...

    2017-01-01

    Organisms throughout biology need to maintain the integrity of their genome. From bacteria to vertebrates, life has established sophisticated mechanisms to detect and eliminate foreign genetic material or to restrict its function and replication. Tremendous progress has been made in the understanding of these mechanisms which keep foreign or unwanted nucleic acids from viruses or phages in check. Mechanisms reach from restriction-modification systems and CRISPR/Cas in bacteria and archaea to RNA interference and immune sensing of nucleic acids, altogether integral parts of a system which is now appreciated as nucleic acid immunity. With inherited receptors and acquired sequence information, nucleic acid immunity comprises innate and adaptive components. Effector functions include diverse nuclease systems, intrinsic activities to directly restrict the function of foreign nucleic acids (e.g., PKR, ADAR1, IFIT1), and extrinsic pathways to alert the immune system and to elicit cytotoxic immune responses. These effects act in concert to restrict viral replication and to eliminate virus-infected cells. The principles of nucleic acid immunity are highly relevant for human disease. Besides its essential contribution to antiviral defense and restriction of endogenous retroelements, dysregulation of nucleic acid immunity can also lead to erroneous detection and response to self nucleic acids then causing sterile inflammation and autoimmunity. Even mechanisms of nucleic acid immunity which are not established in vertebrates are relevant for human disease when they are present in pathogens such as bacteria, parasites, or helminths or in pathogen-transmitting organisms such as insects. This review aims to provide an overview of the diverse mechanisms of nucleic acid immunity which mostly have been looked at separately in the past and to integrate them under the framework nucleic acid immunity as a basic principle of life, the understanding of which has great potential to

    There is a need to review/revise recommendations about existing vaccines in light of recent developments in the field of vaccinology. Following an IAP ACVIP meeting on April 19 and 20, 2014, a draft of revised recommendations for the year 2014 and updates on certain vaccine formulations was prepared and circulated among the meeting participants to arrive at a consensus. To review and revise recommendations for 2014 Immunization timetable for pediatricians in office practice and issue statements on certain new and existing vaccine formulations. The major changes in the 2014 Immunization Timetable include two doses of MMR vaccine at 9 and 15 months of age, single dose recommendation for administration of live attenuated H2 strain hepatitis A vaccine, inclusion of two new situations in high-risk category of children in context with pre-exposure prophylaxis of rabies, creation of a new slot at 9-12 months of age for typhoid conjugate vaccine for primary immunization, and recommendation of two doses of human papilloma virus vaccines with a minimum interval of 6 months between doses for primary schedule of adolescent/preadolescent girls aged 9-14 years. There would not be any change to the committee's last year's (2013) recommendations on pertussis vaccination and administration schedule of monovalent human rotavirus vaccine. There is no need of providing additional doses of whole-cell pertussis vaccine to children who have earlier completed their primary schedule with acellular pertussis vaccine-containing products. A brief update on the new Indian Rotavirus vaccine, 116E is also provided. The committee has reviewed and offered its recommendations on the currently available pentavalent vaccine (DTwP+Hib+Hepatitis-B) combinations in Indian market. The comments and footnotes for several vaccines are also updated and revised.

     We investigated a measles outbreak among healthcare workers (HCWs) by assessing laboratory characteristics, measles vaccine effectiveness, and serological correlates for protection.  Cases were laboratory-confirmed measles in HCWs from hospital X during weeks 12-20 of 2014. We assessed cases' severity and infectiousness by using a questionnaire. We tested cases' sera for measles immunoglobulin M, immunoglobulin G, avidity, and plaque reduction neutralization (PRN). Throat swabs and oral fluid samples were tested by quantitative polymerase chain reaction. We calculated attack rates (ARs) by vaccination status and estimated measles vaccine effectiveness as 1 - [ARvaccinated/ARunvaccinated].  Eight HCWs were notified as measles cases; 6 were vaccinated with measles vaccine twice, 1 was vaccinated once, and 1 was unvaccinated. All 6 twice-vaccinated cases had high avidity and PRN titers. None reported severe measles or onward transmission. Two of 4 investigated twice-vaccinated cases had pre-illness PRN titers of >120 mIU/mL. Among 106 potentially exposed HCWs, the estimated effectiveness of 2 doses of measles vaccine was 52% (95% confidence interval [CI], -207%-93%).  Measles occurred in 6 twice-vaccinated HCWs, despite 2 having adequate pre-exposure neutralizing antibodies. None of the twice-vaccinated cases had severe measles, and none had onward transmission, consistent with laboratory findings suggesting a secondary immune response. Improving 2-dose MMR coverage among HCWs would have likely reduced the size of this outbreak. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

    Innate and adaptive immunity play a significant role in urogenital infections. Innate immunity is provided by the epithelial cells and mucus lining along with acidic pH, which forms a strong physical barrier against the pathogens in female reproductive tract. Cells of innate immune system, antimicrobial peptides, cytokines, chemokines and adaptive immunity in the reproductive tract are evolved during infection, and a pro-inflammatory response is generated to fight against the invading pathogen Trichomonas vaginalis, a primary urogenital protozoa, the etiological agent of human trichomoniasis, a curable sexually transmitted infection. The involvement of the urogenital tract by other protozoal infections such as P. falciparum, Trypanosoma, Leishmania, Toxoplasma, Entamoeba histolytica and Acanthamoeba infection is rarely reported. Trichomonas induce pro-inflammatory and immunosuppressive responses in infected subjects. Multifactorial pathogenic mechanisms including parasite adherence, cysteine proteases, lipophosphoglycan, free radical, cytokine generation and Toll-like receptors appear to interplay with the induction of local and systemic immune responses that ultimately determine the outcome of the infection. However, the involvement of urogenital pathogen-specific immune mechanisms and effect of normal local resident flora on the outcome (symptomatic vs. asymptomatic) of infection are poorly understood. Moreover, immune interactions in trichomoniasis subjects co-infected with bacterial and viral pathogens need to be elucidated.

    In a previous paper the authors argued the case for incorporating ideas from innate immunity into artificial immune systems (AISs) and presented an outline for a conceptual framework for such systems. A number of key general properties observed in the biological innate and adaptive immune systems were highlighted, and how such properties might be instantiated in artificial systems was discussed in detail. The next logical step is to take these ideas and build a software system with which AISs with these properties can be implemented and experimentally evaluated. This paper reports on the results of that step - the libtissue system.

    The visualization of the dynamic behaviour of and interactions between immune cells using time-lapse video microscopy has an important role in modern immunology. To draw robust conclusions, quantification of such cell migration is required. However, imaging experiments are associated with various artefacts that can affect the estimated positions of the immune cells under analysis, which form the basis of any subsequent analysis. Here, we describe potential artefacts that could affect the interpretation of data sets on immune cell migration. We propose how these errors can be recognized and corrected, and suggest ways to prevent the data analysis itself leading to biased results.

    MOTIVATION: The recognition of antigenic peptides is a major event of an immune response. In current mesoscopic-scale simulators of the immune system, this crucial step has been modeled in a very approximated way. RESULTS: We have equipped an agent-based model of the immune system with immuno......-informatics methods to allow the simulation of the cardinal events of the antigenic recognition, going from single peptides to whole proteomes. The recognition process accounts for B cell-epitopes prediction through Parker-scale affinity estimation, class I and II HLA peptide prediction and binding through position...

    To evaluate the economic impact of the 2009 routine US childhood immunization schedule, including diphtheria and tetanus toxoids and acellular pertussis, Haemophilus influenzae type b conjugate, inactivated poliovirus, measles/mumps/rubella, hepatitis B, varicella, 7-valent pneumococcal conjugate, hepatitis A, and rotavirus vaccines; influenza vaccine was not included. Decision analysis was conducted using population-based vaccination coverage, published vaccine efficacies, historical data on disease incidence before vaccination, and disease incidence reported during 2005 to 2009. Costs were estimated using the direct cost and societal (direct and indirect costs) perspectives. Program costs included vaccine, administration, vaccine-associated adverse events, and parent travel and work time lost. All costs were inflated to 2009 dollars, and all costs and benefits in the future were discounted at a 3% annual rate. A hypothetical 2009 US birth cohort of 4,261,494 infants over their lifetime was followed up from birth through death. Net present value (net savings) and benefit-cost ratios of routine childhood immunization were calculated. Analyses showed that routine childhood immunization among members of the 2009 US birth cohort will prevent ∼42,000 early deaths and 20 million cases of disease, with net savings of $13.5 billion in direct costs and $68.8 billion in total societal costs, respectively. The direct and societal benefit-cost ratios for routine childhood vaccination with these 9 vaccines were 3.0 and 10.1. From both direct cost and societal perspectives, vaccinating children as recommended with these vaccines results in substantial cost savings.

    Immunity rules are part and parcel of the law of international organizations. It has long been accepted that international organizations and their staff need to enjoy immunity from the jurisdiction of national courts. However, it is the application of these rules in practice that increasingly causes controversy. Claims against international organizations are brought before national courts by those who allegedly suffer from their activities. These can be both natural and legal persons such as companies. National courts, in particular lower courts, have often been less willing to recognize the immunity of the organization concerned than the organization s founding fathers. Likewise, public opinion and legal writings frequently criticize international organizations for invoking their immunity and for the lack of adequate means of redress for claimants. It is against this background that an international conference was organized at Leiden University in June 2013. A number of highly qualified academics and practit...

    2011-11-01

    Although a variety of virus species can infect amphibians, diseases caused by ranaviruses ([RVs]; Iridoviridae) have become prominent, and are a major concern for biodiversity, agriculture and international trade. The relatively recent and rapid increase in prevalence of RV infections, the wide range of host species infected by RVs, the variability in host resistance among population of the same species and among different developmental stages, all suggest an important involvement of the amphibian immune system. Nevertheless, the roles of the immune system in the etiology of viral diseases in amphibians are still poorly investigated. We review here the current knowledge of antiviral immunity in amphibians, focusing on model species such as the frog Xenopus and the salamander (Ambystoma tigrinum), and on recent progress in generating tools to better understand how host immune defenses control RV infections, pathogenicity, and transmission.

Neuroinflammation occurs in close relation to trauma, infection, and neurodegenerative diseases. Low-level neuroinflammation is considered to have beneficial effects whereas chronic neuroinflammation can be harmful. Innate immune system consisting of pattern-recognition receptors, macrophages, and complement system plays a key role in CNS homeostasis following injury and infection. Here, we discuss how innate immune components can also contribute to neuroinflammation and neurodegeneration.

    All organisms are connected in a complex web of relationships. Although many of these are benign, not all are, and everything alive devotes significant resources to identifying and neutralizing threats from other species. From bacteria through to primates, the presence of some kind of effective immune system has gone hand in hand with evolutionary success. This article focuses on mammalian immunity, the challenges that it faces, the mechanisms by which these are addressed, and the consequences that arise when it malfunctions.

    Full Text Available The mammalian intestinal tract is the largest immune organ in the body and comprises cells from non-hemopoietic (epithelia, Paneth cells, goblet cells and hemopoietic (macrophages, dendritic cells, T-cells origin, and is also a dwelling for trillions of microbes collectively known as the microbiota. The homeostasis of this large microbial biomass is prerequisite to maintain host health by maximizing beneficial symbiotic relationships and minimizing the risks of living in such close proximity. Both microbiota and host immune system communicate with each other to mutually maintain homeostasis in what could be called a "love-hate relationship." Further, the host innate and adaptive immune arms of the immune system cooperate and compensate each other to maintain the equilibrium of a highly complex gut ecosystem in a stable and stringent fashion. Any imbalance due to innate or adaptive immune deficiency or aberrant immune response may lead to dysbiosis and low-grade to robust gut inflammation, finally resulting in metabolic diseases.

    The biological immune system is a robust, complex, adaptive system that defends the body from foreign pathogens. It is able to categorize all cells (or molecules) within the body as self-cells or non-self cells. It does this with the help of a distributed task force that has the intelligence to take action from a local and also a global perspective using its network of chemical messengers for communication. There are two major branches of the immune system. The innate immune system is an unchanging mechanism that detects and destroys certain invading organisms, whilst the adaptive immune system responds to previously unknown foreign cells and builds a response to them that can remain in the body over a long period of time. This remarkable information processing biological system has caught the attention of computer science in recent years. A novel computational intelligence technique, inspired by immunology, has emerged, called Artificial Immune Systems. Several concepts from the immune have been extracted an...

  17. Military Healthcare Battlefield Immunity.

    Kelly, J C

    2012-12-01

    The combatant soldier on the battlefield remains protected from any claim in negligence by the doctrine of combat immunity for any negligent act or omission they may make when fighting. In other words, the combatant soldier does not owe a fellow soldier a duty of care on the battlefield, as the duty of care is non-justiciable. However, the non-combatant Military Healthcare Professional, although sometimes operating in the same hostile circumstances as the fighting soldier, is unlikely to benefit from combat immunity for any clinical negligence on the battlefield. This is because they continue to owe their patient a duty of care, although this has not been tested in the courts. This paper considers if any military healthcare professional could ever benefit from combat immunity, which is unlikely due to their non-combatant status. Instead, this paper suggests that a modified form of immunity; namely, Military Healthcare Battlefield Immunity could be a new, unique and viable doctrine, however, this could only be granted in rare circumstances and to a much lesser degree than combat immunity.

    Full Text Available La publicación del artículo de Wakefield et al. en The Lancet desencadenó una reacción de rechazo a la vacuna triple vírica, a pesar de que se trataba solo de una serie de casos y la asociación entre la vacunación y el autismo hubiera podido muy bien ser anecdótica. Sin embargo, más tarde se comprobó que tal asociación era espuria, debido no solo a sesgos ocultados sino también a alteraciones interesadas de los datos y a otros comportamientos impropios de dos de los autores que por ello fueron expulsados del colegio de médicos. Finalmente el artículo fue retirado de la revista. Este episodio invita a reflexionar sobre la credibilidad y la confianza que merecen las autoridades y los profesionales a la población, así como sobre los recelos que pueden plantearse cuando se producen potenciales conflictos de intereses entre los profesionales, la industria, las revistas y la población. Un aspecto de particular interés es el de las expectativas distorsionadas sobre las posibilidades de las intervenciones sanitarias, incluida la vacunación, especialmente respecto de la dimensión individual y la colectiva de la prevención.The paper of Wakefield et al. in The Lancet, triggered a negative reaction to the MMR vaccine, even though it was just a series of cases and the association between vaccination and autism could well be anecdotal.

    The extended immunization campaign began in the mid 1980s and contributed to immunization of 4 out of every 5 infants worldwide, or 80% by the end of the 1980s. There was a slight relaxation of effort around 1990 and 1991, and declines occurred in 28 developing countries. In developing countries, 101 countries maintained or increased immunization in 1991. Rates dropped in Brazil and Venezuela and sub-Saharan Africa. Rates remained constant in 1992, except for the declines in women's tetanus immunization. Distribution is 4-5 times a year to 100 million infants. The savings in lives amounted to 3 million 1992, and further extension could have saved another 1.7 million. The cost in low income countries is $6 to $20, with an average of $15. Five visits are required for complete immunization into one dose; costs could then be reduced by 70%. Total annual costs amount to $2.2 to $2.4 billion for the United Nations Expanded Programme on Immunization. This sum amounts to 2% of public health expenditures in developing countries. The benefits are in reduction in health care costs and expanded productive potential of people. The measles vaccine alone reduced the death rate from 2.5 million in 1980 to 900,000 in 1990. Nonfatal measles morbidity was reduced from 75 million to 25 million for the same period. From averted measles incidents, the savings in treatment costs and productive potential are immeasurable. The first smallpox vaccine was developed in 1796 by Edward Jenner, but it took nearly two for final smallpox eradication in 1979 worldwide. Over the past 10 years, polio eradication has cost $1.4 billion, but without polio vaccines, the cost would reach $500 million annually. Refrigeration and transportation to remote areas has made immunization difficult. The development of low-dose vaccines that would maintain potency in tropical temperatures would be a welcome contribution.
