    Full Text Available Abstract Background Accurate reporting of adverse events occurring after vaccination is an important component of determining risk-benefit ratios for vaccinations. Controversy has developed over alleged underreporting of adverse events within U.S. military samples. This report examines the accuracy of adverse event rates recently published for headaches, and examines the issue of underreporting of headaches as a function of civilian or military sources and as a function of passive versus active surveillance. Methods A report by Sejvar et al was examined closely for accuracy with respect to the reporting of neurologic adverse events associated with smallpox vaccination in the United States. Rates for headaches were reported by several scholarly sources, in addition to Sejvar et al, permitting a comparison of reporting rates as a function of source and type of surveillance. Results Several major errors or omissions were identified in Sejvar et al. The count of civilian subjects vaccinated and the totals of both civilians and military personnel vaccinated were reported incorrectly by Sejvar et al. Counts of headaches reported in VAERS were lower (n = 95 for Sejvar et al than for Casey et al (n = 111 even though the former allegedly used 665,000 subjects while the latter used fewer than 40,000 subjects, with both using approximately the same civilian sources. Consequently, rates of nearly 20 neurologic adverse events reported by Sejvar et al were also incorrectly calculated. Underreporting of headaches after smallpox vaccination appears to increase for military samples and for passive adverse event reporting systems. Conclusion Until revised or corrected, the rates of neurologic adverse events after smallpox vaccinated reported by Sejvar et al must be deemed invalid. The concept of determining overall rates of adverse events by combining small civilian samples with large military samples appears to be invalid. Reports of headaches as adverse events

    Few diseases can match the enormous impact that smallpox has had on mankind. Its influence can be seen in the earliest recorded histories of ancient civilizations in Egypt and Mesopotamia. With fatality rates up to 30%, smallpox left its survivors with extensive scarring and other serious sequelae. It is estimated that smallpox killed 500 million people in the 19th and 20th centuries. Given the ongoing concerns regarding the use of variola as a biological weapon, this review will focus on the licensed vaccines as well as current research into next-generation vaccines to protect against smallpox and other poxviruses.

    Smallpox has shaped human history, from the earliest human civilizations well into the 20th century. With high mortality rates, rapid transmission, and serious long-term effects on survivors, smallpox was a much-feared disease. The eradication of smallpox represents an unprecedented medical victory for the lasting benefit of human health and prosperity. Concerns remain, however, about the development and use of the smallpox virus as a biological weapon, which necessitates the need for continued vaccine development. Smallpox vaccine development is thus a much-reviewed topic of high interest. This review focuses on the current state of smallpox vaccines and their context in biodefense efforts.

    Smallpox was eradicated 34 years ago due to the success of the smallpox vaccine; yet, the vaccine continues to be studied because of its importance in responding to potential biological warfare and the adverse events associated with current smallpox vaccines. Interindividual variations in vaccine response are observed and are, in part, due to genetic variation. In some cases, these varying responses lead to adverse events, which occur at a relatively high rate for the smallpox vaccine compared with other vaccines. Here, we aim to summarize the cytokine responses associated with smallpox vaccine response to date. Along with a description of each of these cytokines, we describe the genetic and adverse event data associated with cytokine responses to smallpox vaccination.

    Full Text Available Smallpox virus has gained considerable attention as a potential bioterrorism agent. Recommendations for smallpox (vaccinia vaccination presume a low risk for use of smallpox as a terrorist biological agent and vaccination is currently recommended for selected groups of individuals such as health care workers, public health authorities, and emergency/rescue workers, among others. Information about adverse reactions to the smallpox vaccine is based upon studies completed during the 1950s and 1960s. The prevalence of various diseases has changed over the last four decades and new disease entities have been described during this period. The smallpox vaccination may be contra-indicated in many of these conditions. This has made pre-screening of potential vaccines necessary. It is believed that at present, the risks of vaccine-associated complications far outweigh the potential benefits of vaccination in the general population.

  12. Smallpox vaccines: targets of protective immunity.

    2011-01-01

    The eradication of smallpox, one of the great triumphs of medicine, was accomplished through the prophylactic administration of live vaccinia virus, a comparatively benign relative of variola virus, the causative agent of smallpox. Nevertheless, recent fears that variola virus may be used as a biological weapon together with the present susceptibility of unimmunized populations have spurred the development of new-generation vaccines that are safer than the original and can be produced by modern methods. Predicting the efficacy of such vaccines in the absence of human smallpox, however, depends on understanding the correlates of protection. This review outlines the biology of poxviruses with particular relevance to vaccine development, describes protein targets of humoral and cellular immunity, compares animal models of orthopoxvirus disease with human smallpox, and considers the status of second- and third-generation smallpox vaccines.

Smallpox (variola is among the most dangerous and highly contagious viral infections affecting humans. The last natural case in Somalia marked the end of a successful World Health Organization campaign for smallpox eradication by vaccination on worldwide scale. Smallpox virus still exists today in some laboratories, specially designated for that purpose. The contemporary response in the treatment of the post-vaccine complications, which would occur upon enforcing new programs for mass-scale smallpox immunization, includes application of effective chemotherapeutics and their combinations. The goals are to provide the highest possible level of protection and safety of the population in case of eventual terrorist attack.

    The review summarizes the archive data on smallpox, history of ancient civilizations, and the most recent data on the genome organization of orthopoxviruses, their evolutionary relationships, and the time points of smallpox emergence. The performed analysis provides the grounds for the hypothesis that smallpox could have emerged several times as a result of evolutionary changes in the zoonotic ancestor virus and disappeared due to insufficient population size of ancient civilizations. Smallpox reemerged in the Indian subcontinent approximately 2500-3000 years before present, which resulted in endemization of this anthroponotic infection, which had been preserved until the smallpox eradication in the 20th century AD. The conclusion suggests a potential possibility of future variola virus reemergence, presenting a great menace for mankind, as well as the need for development of new safe smallpox vaccines, design of anti-smallpox drugs, and activation of the control of zoonotic human orthopoxvirus infections.

    WHO is now celebrating more than 30 years of freedom from smallpox. What was originally seen as a victory over an ancient scourge can now be viewed as an epidemiologically driven programme to overcome governmental inertia and under-achievement in delivering an off-patent vaccine. Though efforts are accelerating global vaccine use, a plea is made to push the world's governments to commit to universal childhood vaccination via a proposed new programme. The latter should begin by exploiting a long list of ever more affordable off-patent vaccines, vaccines that can virtually eliminate the bulk of the world's current vaccine-preventable disease burden.

    Smallpox inarguably shaped the course of human history by killing countless millions in both the Old World and the New World. Dr. Edward Jenner's discovery of vaccination in the late 18th century, and the global eradication of smallpox in the 1970s, rank among the greatest achievements in human history. Amidst recent growing concerns about bioterrorism, smallpox vaccination has resurfaced from the history books to become a topic of major importance. Inoculation with vaccinia virus is highly effective for the prevention of smallpox infection, but it is associated with several known side effects that range from mild and self-limited to severe and life-threatening. As the United States moves forward with plans to vaccinate selected health care workers and the military, and perhaps offer the vaccination to all citizens in the future, it is important to fully understand and appreciate the history, risks, and benefits of smallpox vaccination.

    This report outlines recommendations for the clinical use of the three smallpox vaccines stored in the U.S. Strategic National Stockpile for persons who are exposed to smallpox virus or at high risk for smallpox infection during a postevent vaccination program following an intentional or accidental release of the virus. No absolute contraindications exist for smallpox vaccination in a postevent setting. However, several relative contraindications exist among persons with certain medical conditions. CDC recommendations for smallpox vaccine use were developed in consideration of the risk for smallpox infection, risk for an adverse event following vaccination, and benefit from vaccination. Smallpox vaccines are made from live vaccinia viruses that protect against smallpox disease. They do not contain variola virus, the causative agent of smallpox. The three smallpox vaccines stockpiled are ACAM2000, Aventis Pasteur Smallpox Vaccine (APSV), and Imvamune. Surveillance and containment activities including vaccination with replication-competent smallpox vaccine (i.e., vaccine viruses capable of replicating in mammalian cells such as ACAM2000 and APSV) will be the primary response strategy for achieving epidemic control. Persons exposed to smallpox virus are at high risk for developing and transmitting smallpox and should be vaccinated with a replication-competent smallpox vaccine unless severely immunodeficient. Because of a high likelihood of a poor immune response and an increased risk for adverse events, smallpox vaccination should be avoided in persons with severe immunodeficiency who are not expected to benefit from vaccine, including bone marrow transplant recipients within 4 months of transplantation, persons infected with HIV with CD4 cell counts smallpox virus exposure in persons with severe immunodeficiency. Persons without a known smallpox virus exposure might still be at high risk for developing smallpox infection depending on the magnitude of the outbreak and

  3. Epidemiologic Assessment of the Protective Effects of Smallpox Vaccination

    Hiroshi Nishiura

    2006-01-01

    Full Text Available Despite smallpox eradication, the widely discussed possibility of a bioterrorist attack using a variola virus makes it necessary to review the epidemiology of smallpox and the effects of various vaccination schemes. This paper provides a literature review concerning the epidemiologic assessment of the protective effects of smallpox vaccination, with particular emphasis on the statistical and theoretical points of view. Although smallpox vaccination has the longest history of all vaccinations, we lack precise epidemiologic estimates of its effectiveness. Vaccination practice continually evolved and many places experienced vaccinations with various strains over time. Despite the weak statistical evidence, it can be stated with certainty that smallpox vaccines prevented infection for a few decades after primary vaccination and that vaccinated individuals had the benefit of a longer lasting partial protection when they contracted the disease. Confronted with the huge uncertainties and with the necessity to rely on laboratory evidence, appropriate preparedness plans for countermeasures using vaccination must be based on the best available evidence.

  4. Pre-event Smallpox Vaccination for Healthcare Workers Revisited – the Need for a Carefully Screened Multidisciplinary Cadre

    Energy Technology Data Exchange (ETDEWEB)

    Malone, JD D.

    2007-03-01

    Abstract As healthcare institutions are a focus of smallpox transmission early in an epidemic, several mathematical models support pre-event smallpox vaccination of healthcare workers (HCWs). The deciding factor for HCW voluntary vaccination is the risk of disease exposure versus the risk of vaccine adverse events. In a United States military population, with careful screening to exclude atopic dermatitis/eczema and immunosuppression, over 1 million vaccinia vaccinations were delivered with 1 fatality attributed to vaccination. Among 37,901 U.S. civilian volunteer healthcare workers vaccinated, 100 serious adverse events were reported including 10 ischemic cardiac episodes and six myocardial infarctions – 2 were fatal. This older population had a higher rate of adverse events due to age related coronary artery disease. T-cell mediated inflammatory processes, induced by live vaccinia vaccination, may have a role in the observed acute coronary artery events. With exclusion of individuals at risk for coronary artery disease, atopic dermatitis/eczema, and immunosuppression, HCWs can be smallpox vaccinated with minimal risk. A smallpox pre-vaccinated multidisciplinary cadre (physician, nurse, infection control practitioner, technician) will supply leadership to deal with fear and uncertainty while limiting spread and initial mortality of smallpox. Stochastic – from the Greek meaning “skillful in aiming” – is currently interpreted as arising from chance and involving probability. This issue’s article “Containing a large bioterrorist smallpox attack: a computer simulation approach” by Longini et al. is a discrete time, stochastic computer simulation model that offers additional planning guidance for a smallpox (variola virus) outbreak (1). Although interpretation of the model’s information may differ, Longini’s article concludes “Given that surveillance and containment measures are in place, preemptive vaccination of hospital workers would further

    The World Health Assembly is scheduled to decide in May 2011 whether the 2 known remaining stockpiles of smallpox virus are to be destroyed or retained. In preparation for this, a WHO-appointed committee undertook a comprehensive review of the status of smallpox virus research from 1999 to 2010. It concluded that, considering the nature of the studies already completed with respect to vaccine, drugs, and diagnostics, there was no reason to retain live smallpox virus except to satisfy restrictive regulatory requirements. The committee advised that researchers and regulators define alternative models for testing the vaccines and drugs. Apart from other considerations, the costs of new products are significant and important. These include prospective expenditures required for the development, manufacture, testing, and storage of new products. This commentary provides approximations of these costs and the incremental contribution that a newly developed vaccine might make in terms of public health security.

A seven-day interval between the injection of the inactivated and live preparations was recommended on the basis of the data obtained.

    May, Thomas; Silverman, Ross D

    2003-06-01

    In June 2002, the Advisory Committee on Immunization Practices (ACIP) approved draft recommendations concerning preparation for potential biological terror attacks that utilize the smallpox virus. ACIP recommends against both mandatory and voluntary vaccination of the general public. The present paper examines the moral and political considerations both for and against each of the general public vaccination options considered by the ACIP in the context of the state's authority over vaccination for the purposes of protecting public health. Although it is clear that compulsory mass vaccination is not justified at this time, the issues surrounding voluntary vaccination are more complex. Should smallpox vaccination prior to an outbreak be made available to the general public? The paper concludes that the vaccine should not be made available at this time. This conclusion, however, is based upon contingent features of current circumstances, which would change once an outbreak occurred. In the even of a terror-related outbreak of smallpox, the general public's access to voluntary vaccination would become justified, even in areas beyond where the outbreak has occurred.

    The recent threat of bioterrorism has fueled debate on smallpox vaccination policy for the United States. Certain policy proposals call for voluntary mass vaccination; however, if individuals decide whether to vaccinate according to self-interest, the level of herd immunity achieved may differ from what is best for the population as a whole. We present a synthesis of game theory and epidemic modeling that formalizes this conflict between self-interest and group interest and shows that voluntary vaccination is unlikely to reach the group-optimal level. This shortfall results in a substantial increase in expected mortality after an attack.

    The recent observation of a surge in human monkeypox in the Democratic Republic of the Congo (DRC) prompts the question of whether cessation of smallpox vaccination is driving the phenomenon, and if so, why is re-emergence not universal throughout the historic geographic range of the virus? Research addressing the virus's mechanisms for immune evasion and induction, as well as that directed at elucidating the genes involved in pathogenesis in different viral lineages (West African vs Congo Basin), provide insights to help explain why emergence appears to be geographically limited. Novel vaccines offer one solution to curtail the spread of this disease.

    We still face a threat of orthopoxviruses in the form of biological weapons and emerging zoonoses. Therefore, there is a need to maintain a comprehensive defense strategy to counter the low-probability, high-impact threat of smallpox, as well as the ongoing threat of naturally occurring orthopoxvirus disease. The currently licensed live-virus smallpox vaccine ACAM2000 is effective, but associated with serious and even life-threatening adverse events. The health threat posed by this vaccine, and other previously licensed vaccines, has prevented many first responders, and even many in the military, from receiving a vaccine against smallpox. At the same time, global immunity produced during the smallpox eradication campaign is waning. Here, we review novel subunit/component vaccines and how they might play roles in unconventional strategies to defend against emerging orthopoxvirus diseases throughout the world and against smallpox used as a weapon of mass destruction.

  16. A brief history of vaccines: smallpox to the present.

    Science.gov (United States)

    Hsu, Jennifer L

    2013-01-01

    Modern vaccine history began in the late 18th century with the discovery of smallpox immunization by Edward Jenner. This pivotal step led to substantial progress in prevention of infectious diseases with inactivated vaccines for multiple infectious diseases, including typhoid, plague and cholera. Each advance produced significant decreases in infection-associated morbidity and mortality, thus shaping our modem cultures. As knowledge of microbiology and immunology grew through the 20th century, techniques were developed for cell culture of viruses. This allowed for rapid advances in prevention of polio, varicella, influenza and others. Finally, recent research has led to development of alternative vaccine strategies through use of vectored antigens, pathogen subunits (purified proteins or polysaccharides) or genetically engineered antigens. As the science of vaccinology continues to rapidly evolve, knowledge of the past creates added emphasis on the importance of developing safe and effective strategies for infectious disease prevention in the 21st century.

  17. Logistics of community smallpox control through contact tracing and ring vaccination: a stochastic network model

    2004-08-01

    Full Text Available Abstract Background Previous smallpox ring vaccination models based on contact tracing over a network suggest that ring vaccination would be effective, but have not explicitly included response logistics and limited numbers of vaccinators. Methods We developed a continuous-time stochastic simulation of smallpox transmission, including network structure, post-exposure vaccination, vaccination of contacts of contacts, limited response capacity, heterogeneity in symptoms and infectiousness, vaccination prior to the discontinuation of routine vaccination, more rapid diagnosis due to public awareness, surveillance of asymptomatic contacts, and isolation of cases. Results We found that even in cases of very rapidly spreading smallpox, ring vaccination (when coupled with surveillance is sufficient in most cases to eliminate smallpox quickly, assuming that 95% of household contacts are traced, 80% of workplace or social contacts are traced, and no casual contacts are traced, and that in most cases the ability to trace 1–5 individuals per day per index case is sufficient. If smallpox is assumed to be transmitted very quickly to contacts, it may at times escape containment by ring vaccination, but could be controlled in these circumstances by mass vaccination. Conclusions Small introductions of smallpox are likely to be easily contained by ring vaccination, provided contact tracing is feasible. Uncertainties in the nature of bioterrorist smallpox (infectiousness, vaccine efficacy support continued planning for ring vaccination as well as mass vaccination. If initiated, ring vaccination should be conducted without delays in vaccination, should include contacts of contacts (whenever there is sufficient capacity and should be accompanied by increased public awareness and surveillance.

    Full Text Available Aysegul Nalca, Elizabeth E ZumbrunCenter for Aerobiological Sciences, US Army Medical Research Institute of Infectious Diseases (USAMRIID, Fort Detrick, MD, USAAbstract: Smallpox was eradicated more than 30 years ago, but heightened concerns over bioterrorism have brought smallpox and smallpox vaccination back to the forefront. The previously licensed smallpox vaccine in the United States, Dryvax® (Wyeth Laboratories, Inc., was highly effective, but the supply was insufficient to vaccinate the entire current US population. Additionally, Dryvax® had a questionable safety profile since it consisted of a pool of vaccinia virus strains with varying degrees of virulence, and was grown on the skin of calves, an outdated technique that poses an unnecessary risk of contamination. The US government has therefore recently supported development of an improved live vaccinia virus smallpox vaccine. This initiative has resulted in the development of ACAM2000™ (Acambis, Inc.™, a single plaque-purified vaccinia virus derivative of Dryvax®, aseptically propagated in cell culture. Preclinical and clinical trials reported in 2008 demonstrated that ACAM2000™ has comparable immunogenicity to that of Dryvax®, and causes a similar frequency of adverse events. Furthermore, like Dryvax®, ACAM2000™ vaccination has been shown by careful cardiac screening to result in an unexpectedly high rate of myocarditis and pericarditis. ACAM2000™ received US Food and Drug Administration (FDA approval in August 2007, and replaced Dryvax® for all smallpox vaccinations in February 2008. Currently, over 200 million doses of ACAM2000™ have been produced for the US Strategic National Stockpile. This review of ACAM2000™ addresses the production, characterization, clinical trials, and adverse events associated with this new smallpox vaccine.Keywords: smallpox, vaccinia, variola, vaccine, efficacy, safety

    Eradication of smallpox and discontinuation of the vaccination campaign resulted in an increase in the percentage of unvaccinated individuals, highlighting the need for postexposure efficient countermeasures in case of accidental or deliberate viral release. Intranasal infection of mice with ectromelia virus (ECTV), a model for human smallpox, is curable by vaccination with a high vaccine dose given up to 3 days postexposure. To further extend this protective window and to reduce morbidity, mice were vaccinated postexposure with Vaccinia-Lister, the conventional smallpox vaccine or Modified Vaccinia Ankara, a highly attenuated vaccine in conjunction with TLR3 or TLR9 agonists. We show that co-administration of the TLR3 agonist poly(I:C) even 5 days postexposure conferred protection, avoiding the need to increase the vaccination dose. Efficacious treatments prevented death, ameliorated disease symptoms, reduced viral load and maintained tissue integrity of target organs. Protection was associated with significant elevation of serum IFNα and anti-vaccinia IgM antibodies, modulation of IFNγ response, and balanced activation of NK and T cells. TLR9 agonists (CpG ODNs) were less protective than the TLR3 agonist poly(I:C). We show that activation of type 1 IFN by poly(I:C) and protection is achievable even without co-vaccination, requiring sufficient amount of the viral antigens of the infective agent or the vaccine. This study demonstrated the therapeutic potential of postexposure immune modulation by TLR activation, allowing to alleviate the disease symptoms and to further extend the protective window of postexposure vaccination.

    Smallpox vaccine is highly effective, inducing protective immunity to smallpox and diseases caused by related orthopoxviruses. Smallpox vaccine efficacy was historically defined by the appearance of a lesion or "take" at the vaccine site, which leaves behind a characteristic scar. Both the take and scar are readily recognizable and were used during the eradication effort to indicate successful vaccination and to categorize individuals as "protected." However, the development of a typical vaccine take may not equate to the successful development of a robust, protective immune response. In this report, we examined two large (>1000) cohorts of recipients of either Dryvax(®) or ACAM2000 using a testing and replication study design and identified subgroups of individuals who had documented vaccine takes, but who failed to develop robust neutralizing antibody titers. Examination of these individuals revealed that they had suboptimal cellular immune responses as well. Further testing indicated these low responders had a diminished innate antiviral gene expression pattern (IFNA1, CXCL10, CXCL11, OASL) upon in vitro stimulation with vaccinia virus, perhaps indicative of a dysregulated innate response. Our results suggest that poor activation of innate antiviral pathways may result in suboptimal immune responses to the smallpox vaccine. These genes and pathways may serve as suitable targets for adjuvants in new attenuated smallpox vaccines and/or effective antiviral therapy targets against poxvirus infections.

    In 1796, Edward Jenner introduced the concept of vaccination with cowpox virus, an Orthopoxvirus within the family Poxviridae that elicits cross protective immunity against related orthopoxviruses, including smallpox virus (variola virus). Over time, vaccinia virus (VACV) replaced cowpox virus as the smallpox vaccine, and vaccination efforts eventually led to the successful global eradication of smallpox in 1979. VACV has many characteristics that make it an excellent vaccine and that were crucial for the successful eradication of smallpox, including (1) its exceptional thermal stability (a very important but uncommon characteristic in live vaccines), (2) its ability to elicit strong humoral and cell-mediated immune responses, (3) the fact that it is easy to propagate, and (4) that it is not oncogenic, given that VACV replication occurs exclusively within the host cell cytoplasm and there is no evidence that the viral genome integrates into the host genome. Since the eradication of smallpox, VACV has experienced a renaissance of interest as a viral vector for the development of recombinant vaccines, immunotherapies, and oncolytic therapies, as well as the development of next-generation smallpox vaccines. This revival is mainly due to the successful use and extensive characterization of VACV as a vaccine during the smallpox eradication campaign, along with the ability to genetically manipulate its large dsDNA genome while retaining infectivity and immunogenicity, its wide mammalian host range, and its natural tropism for tumor cells that allows its use as an oncolytic vector. This review provides an overview of new uses of VACV that are currently being explored for the development of vaccines, immunotherapeutics, and oncolytic virotherapies.

    Full Text Available Abstract Background The United States is implementing plans to immunize 500,000 hospital-based healthcare workers against smallpox. Vaccination is voluntary, and it is unknown what factors drive vaccine acceptance. This study's aims were to estimate the proportion of workers willing to accept vaccination and to identify factors likely to influence their decisions. Methods The survey was conducted among physicians, nurses, and others working primarily in emergency departments or intensive care units at 21 acute-care hospitals in 10 states during the two weeks before the U.S. national immunization program for healthcare workers was announced in December 2002. Of the questionnaires distributed, 1,165 were returned, for a response rate of 81%. The data were analyzed by logistic regression and were adjusted for clustering within hospital and for different number of responses per hospital, using generalized linear mixed models and SAS's NLMIXED procedure. Results Sixty-one percent of respondents said they would definitely or probably be vaccinated, while 39% were undecided or inclined against it. Fifty-three percent rated the risk of a bioterrorist attack using smallpox in the United States in the next two years as either intermediate or high. Forty-seven percent did not feel well-informed about the risks and benefits of vaccination. Principal concerns were adverse reactions and the risk of transmitting vaccinia. In multivariate analysis, four variables were associated with willingness to be vaccinated: perceived risk of an attack, self-assessed knowledge about smallpox vaccination, self-assessed previous smallpox vaccination status, and gender. Conclusions The success of smallpox vaccination efforts will ultimately depend on the relative weight in people's minds of the risk of vaccine adverse events compared with the risk of being exposed to the disease. Although more than half of the respondents thought the likelihood of a bioterrorist smallpox

    Freeze-dried live attenuated smallpox vaccine LC16m8 prepared in cell culture has been the sole smallpox vaccine licensed in Japan since 1975 and was recently recommended as a WHO stockpile vaccine. We evaluated the safety of recently remanufactured lots of LC16m8 using a series of immunodeficient mouse models. These models included suckling mice, severe combined immunodeficiency disease (SCID) mice, and wild-type mice treated with cyclosporine. LC16m8 showed extremely low virulence in each of the three mouse models compared with that of its parental strains, Lister and LC16mO. These results provide further evidence that LC16m8 is one of the safest replication-competent smallpox vaccines in the world and may be considered for use in immunodeficient patients.

    Possible smallpox reemergence drives research for third-generation vaccines that effectively neutralize variola virus. A comparison of neutralization assays using different substrates, variola and vaccinia (Dryvax and modified vaccinia Ankara [MVA]), showed significantly different 90% neutralization titers; Dryvax underestimated while MVA overestimated variola neutralization. Third-generation vaccines may rely upon neutralization as a correlate of protection.

    In the last decade, the research on smallpox vaccine has been paid much more attention because of the special position of variola virus in bioterrorism and biological warfare. To date, 4 generations of smallpox vaccines have been developed, and of which 3 generations can be used. Among them, the first generation smallpox vaccines play an important role in the achievement of global smallpox eradication, but their adverse reactions are strong. The second generation smallpox vaccines possess the theoretical advantages conferred by improved manufacturing process and lowered risk of contamination by adventitious agents. The third generation smallpox vaccines have reduced virulence and improved safety, but the immunological efficacy has also descended. The fourth generation smallpox vaccines are developed by techniques for genetic engineering, and the efficacy remains to be evaluated. Owing to global smallpox eradication, the evaluation of the immunological efficacy of new smallpox vaccines becomes the key procedure which can hinder the development of new vaccines.%鉴于天花病毒在生物恐怖和生物战中的特殊地位,近十年来,天花疫苗的研究重新得到重视.到目前为止,天花疫苗研究已进入第四代,已有三代天花疫苗可供使用.其中,第一代天花疫苗在全球消灭天花中起到重要和关键的作用,但不良反应较强.第二代疫苗改进了生产工艺,降低了外源因子污染的可能.第三代疫苗有效地降低了疫苗的毒力,增强了安全性,但免疫效力有所下降.第四代疫苗系使用基因工程技术研制的疫苗,效果尚待评价.由于天花已经消灭,在新疫苗的研究中,如何评价其免疫效果成为妨碍疫苗研究进展的关键环节.

  11. The discontinuation of routine smallpox vaccination in the United States, 1960-1976: an unlikely affirmation of biomedical hegemony.

    Rich, Miriam

    2011-02-01

    This article seeks to understand the discursive context of the cessation of routine smallpox vaccination in the United States in the early 1970s. The United States has a long tradition of opposition to compulsory smallpox vaccination, usually expressed in terms of concerns about personal liberties, the extent of state authority, and challenges to the hegemony of orthodox biomedicine. The practice of routine smallpox vaccination continued in the United States until its termination in the 1970s, following a 1971 recommendation against the practice issued by the United States Public Health Service. This history investigates the ways in which opposition to compulsory smallpox vaccination in the 1960s and 70s was articulated and understood by contemporaries through an analysis of the rhetoric used in leading medical journals and popular newspapers. It finds that this ultimately successful movement to end routine smallpox vaccination drew upon the language of biomedical authority rather than political protest.

    To evaluate the need to revaccinate laboratory workers against smallpox, we assessed regular revaccination at the US Laboratory Response Network's variola testing sites by examining barriers to revaccination and the potential for persistence of immunity. Our data do not provide evidence to suggest prolonging the recommended interval for revaccination.

    There are three identifiable phases in comparing vaccination policy in England, Prussia and Imperial Germany. (1) Prior to the 1870's the tradition of medical police in Prussia resulted in the vaccination of the population being treated as a State responsibility earlier than in England and provided an appropriate administrative framework. The administrative pressure that could be exerted persuaded the Prussian authorities that legislation to make vaccination compulsory was unnecessary. In contrast, England and Wales lacked both the tradition and administrative structures of a medical police. Legislation (1840, 1853) for free and universal infant vaccination was followed by radical ideological and administrative innovation. (2) From 1875 to 1889 both countries provided free and compulsory vaccination for all. In England this was limited to infants; in Germany including Prussia, it included the re-vaccination of children. (3) After 1889 England and Germany began to diverge more sharply. In England vaccination rates fell and after 1898 conscientious objectors were excused from having to have their children vaccinated. Germany retained compulsory vaccination and rates in the two countries increasingly diverged. England came to rely on the local public health administration for the surveillance and containment of smallpox, including selective vaccination of contacts. Despite these differences smallpox mortality dropped sharply in both countries, although in Germany somewhat earlier. The English reliance on surveillance and containment prefigures that of the WHO in the eradication of smallpox in the Third World. It suggests that the emphasis on the importance of high levels of mass vaccination in the German literature should perhaps be revised.

    Vaccinia Tian Tan (VTT) was used as a vaccine against smallpox in China for millions of people before 1980, yet the biological characteristics of the virus remain unclear. We have characterized VTT with respect to its host cell range, growth properties in vitro, and virulence in vivo. We found that 11 of the 12 mammalian cell lines studied are permissive to VTT infection whereas one, CHO-K1, is non-permissive. Using electron microscopy and sequence analysis, we found that the restriction of VTT replication in CHO-K1 is at a step before viral maturation probably due to the loss of the V025 gene. Moreover, VTT is significantly less virulent than vaccinia WR but remains neurovirulent in mice and causes significant body weight loss after intranasal inoculation. Our data demonstrate the need for further attenuation of VTT to serve either as a safer smallpox vaccine or as a live vaccine vector for other pathogens.

    We previously reported HLA allelic associations with vaccinia virus (VACV)-induced adaptive immune responses in a cohort of healthy individuals (n = 1,071 subjects) after a single dose of the licensed smallpox (Dryvax) vaccine. This study demonstrated that specific HLA alleles were significantly associated with VACV-induced neutralizing antibody (NA) titers (HLA-B*13:02, *38:02, *44:03, *48:01, and HLA-DQB1*03:02, *06:04) and cytokine (HLA-DRB1*01:03, *03:01, *10:01, *13:01, *15:01) immune responses. We undertook an independent study of 1,053 healthy individuals and examined associations between HLA alleles and measures of adaptive immunity after a single dose of Dryvax-derived ACAM2000 vaccine to evaluate previously discovered HLA allelic associations from the Dryvax study and determine if these associations are replicated with ACAM2000. Females had significantly higher NA titers than male subjects in both study cohorts [median ID50 discovery cohort 159 (93, 256) vs. 125 (75, 186), p smallpox vaccine-induced adaptive immune responses are significantly influenced by HLA gene polymorphisms.

  17. Game theory of pre-emptive vaccination before bioterrorism or accidental release of smallpox.

    Molina, Chai; Earn, David J D

    2015-06-01

    Smallpox was eradicated in the 1970s, but new outbreaks could be seeded by bioterrorism or accidental release. Substantial vaccine-induced morbidity and mortality make pre-emptive mass vaccination controversial, and if vaccination is voluntary, then there is a conflict between self- and group interests. This conflict can be framed as a tragedy of the commons, in which herd immunity plays the role of the commons, and free-riding (i.e. not vaccinating pre-emptively) is analogous to exploiting the commons. This game has been analysed previously for a particular post-outbreak vaccination scenario. We consider several post-outbreak vaccination scenarios and compare the expected increase in mortality that results from voluntary versus imposed vaccination. Below a threshold level of post-outbreak vaccination effort, expected mortality is independent of the level of response effort. A lag between an outbreak starting and a response being initiated increases the post-outbreak vaccination effort necessary to reduce mortality. For some post-outbreak vaccination scenarios, even modest response lags make it impractical to reduce mortality by increasing post-outbreak vaccination effort. In such situations, if decreasing the response lag is impossible, the only practical way to reduce mortality is to make the vaccine safer (greater post-outbreak vaccination effort leads only to fewer people vaccinating pre-emptively).

    Full Text Available CONTEXT: In March 2003, the French Ministry of Health implemented a program on preparedness and response to a biological attack using smallpox as weapon. This program included the establishment of a preoutbreak national team that could be revaccinated against smallpox. OBJECTIVE: To identify demographic and clinical factors associated with vaccination success defined as the presence of a pustule at the inoculation site at day 8 (days 7-9, with an undiluted vaccinia virus derived from a Lister strain among preimmunized volunteers. VOLUNTEERS AND METHODS: From March 2003 to November 2006, we have studied prospectively 226 eligible volunteers. Demographic data were recorded for each volunteer (age, sex, number of previously smallpox vaccinations and date of the last vaccination. Smallpox vaccine adverse reactions were diagnosed on the basis of clinical examination performed at days 0, 7, 14, 21 and 28 after revaccination. RESULTS: A total of 226 volunteers (sex ratio H/F = 2.7 were revaccinated. Median age was 45 years (range: 27-63 yrs. All volunteers completed follow-up. Median number of vaccinations before revaccination was 2 (range: 1-8. The median delay between time of the study and the last vaccination was 29 years (range; 18-60 yrs. Sixty-one volunteers (27% experienced one (n = 40 or more (n = 21 minor side effects during the 2-14 days after revaccination. Successful vaccination was noted in 216/226 volunteers (95.6% at day 8 and the median of the pustule diameter was 5 mm (range: 1-20 mm. Size of the pustule at day 8 was correlated with age (p = 0.03 and with the presence of axillary adenopathy after revaccination (p = 0.007. Sex, number of prior vaccinations, delay between the last vaccination and revaccination, and local or systemic side effects with the exception of axillary adenopathy, were not correlated with the size of the pustule at day 8. CONCLUSIONS: Previously vaccinated volunteers can be successfully revaccinated with the

    2015-06-01

    In 1947, a smallpox outbreak occurred in New York City with a total of twelve cases and two deaths. In order to contain this outbreak, the New York City Department of Health launched a mass immunization campaign that over a period of some 60 days vaccinated 6.35 million people. This article examines in detail the epidemiology of this outbreak and the measures employed to contain it. In 1976, a swine influenza strain was isolated among a few recruits at a US Army training camp at Fort Dix, New Jersey. It was concluded at the time that this virus possibly represented a re-appearance of the 1918 influenza pandemic influenza strain. As a result, a mass national immunization program was launched by the federal government. From its inception, the program encountered a myriad of challenges ranging from doubts that it was even necessary to the development of Guillain-Barré paralysis among some vaccine recipients. This paper examines the planning for and implementation of the swine flu immunization program in New York City. It also compares it to the smallpox vaccination program of 1947. Despite equivalent financial and personnel resources, leadership and organizational skills, the 1976 program only immunized approximately a tenth of the number of New York City residents vaccinated in 1947. The reasons for these marked differences in outcomes are discussed in detail.

    The National Smallpox Vaccine in Pregnancy Registry (NSVIPR) actively follows women inadvertently vaccinated with smallpox vaccine during or shortly before pregnancy to evaluate their reproductive health outcomes. Approximately 65% of NSVIPR participants also inadvertently received Anthrax Vaccine Adsorbed (AVA) while pregnant, providing a ready opportunity to evaluate pregnancy and infant health outcomes among these women. AVA-exposed pregnancies were ascertained using NSVIPR and electronic healthcare data. Rates of pregnancy loss and infant health outcomes, including major birth defects, were compared between AVA-exposed and AVA-unexposed pregnancies. Analyses included AVA-exposed and AVA-unexposed pregnant women who also received smallpox vaccine 28 days prior to or during pregnancy. Rates of adverse outcomes among the AVA-exposed group were similar to or lower than expected when compared with published reference rates and the AVA-unexposed population. The findings provide reassurance of the safety of AVA when inadvertently received by a relatively young and healthy population during pregnancy.

  1. Taking advantage of the positive side-effects of smallpox vaccination.

    Mayr, A

    2004-06-01

    From the introduction of smallpox vaccination approximately 200 years ago right up to its discontinuation (1980), reports by physicians and scientists about positive side-effects such as healing of chronic skin rashes, reduced susceptibility to various infectious diseases, e.g. measles, scarlet fever and whooping cough, and even the prophylactic use of the vaccination, e.g. against syphilis, were published again and again. Comparison with the period after cessation of vaccination confirms the experiences of the above vaccinators. As early as 1956, targeted research on these observations led to evidence of the 'ring-zone phenomenon', i.e. the production of soluble antiviral substances in infected chicken embryos and cell cultures. With the help of modern immunological and bioengineering methods, it was later possible to demonstrate that these effects are based on the activation of lymphoreticular cells and the regulatory effect of certain cytokines within the context of the non-specific immune system. These findings led to the development of paramunization with paraspecific vaccines from highly attenuated animal pox viruses. During attenuation, deletions in the virus DNA occur. Attenuated animal pox strains are therefore suited for the production of vector vaccines. The fact that these vector vaccines demonstrate an especially high level of paraspecific efficacy and lack harmful effects is likewise the result of the attenuated animal pox viruses. Optimum regulation of the entire immune system leads to increased paramunity already in the first few days after vaccination and to enhanced antigen recognition and thus accelerated commencement of specific immunity.

    Full Text Available Conventional smallpox vaccines based on replicating vaccinia virus (VV strains (e.g. Lister Elstree, NYCBOH are associated with a high incidence of myo-/pericarditis, a severe inflammatory cardiac complication. A new smallpox vaccine candidate based on a non-replicating Modified Vaccinia Ankara (MVA poxvirus has been assessed for cardiac safety in a large placebo-controlled clinical trial.Cardiac safety of one and two doses of MVA compared to placebo was assessed in 745 healthy subjects. Vaccinia-naïve subjects received either one dose of MVA and one dose of placebo, two doses of MVA, or two doses of placebo by subcutaneous injection four weeks apart; vaccinia-experienced subjects received a single dose of MVA. Solicited and unsolicited adverse events (AE and cardiac safety parameters (recorded as Adverse Events of Special Interest, AESI were monitored after each injection.A total of 5 possibly related AESI (3 cases of palpitations, 2 of tachycardia were reported during the study. No case of myo- or pericarditis occurred. One possibly related serious AE (SAE was reported during the 6-month follow-up period (sarcoidosis. The most frequently observed AEs were injection site reactions.Vaccination with MVA was safe and well tolerated and did not increase the risk for development of myo-/pericarditis.ClinicalTrials.gov NCT00316524.

    LC16m8 is a live, attenuated, cell-cultured smallpox vaccine that was developed and licensed in Japan in the 1970s, but was not used in the campaign to eradicate smallpox. In the early 2000s, the potential threat of bioterrorism led to reconsideration of the need for a smallpox vaccine. Subsequently, LC16m8 production was restarted in Japan in 2002, requiring re-evaluation of its safety and efficacy. Approximately 50,000 children in the 1970s and about 3500 healthy adults in the 2000s were vaccinated with LC16m8 in Japan, and 153 adults have been vaccinated with LC16m8 or Dryvax in phase I/II clinical trials in the USA. These studies confirmed the safety and efficacy of LC16m8, while several studies in animal models have shown that LC16m8 protects the host against viral challenge. The World Health Organization Strategic Advisory Group of Experts on Immunization recommended LC16m8, together with ACAM2000, as a stockpile vaccine in 2013. In addition, LC16m8 is expected to be a viable alternative to first-generation smallpox vaccines to prevent human monkeypox.

    Vaccines may have non-specific effects as suggested mainly in mortality studies from low-income countries. The objective was to examine the effects of BCG and smallpox vaccinations on subsequent risk of lymphoma and leukaemia in a Danish population experiencing rapid out-phasing of these vaccines...... cohort and analysed in a case-cohort design. BCG vaccination reduced the risk of lymphomas (HR=0.49 (95% CI: 0.26-0.93)), whereas smallpox vaccination did not (HR=1.32 (0.56-3.08)). With the small number of leukaemia cases, the analysis of leukaemia had limited power (BCG vaccination HR=0.81 (0.......31-2.16); smallpox vaccination HR=1.32 (0.49-3.53)). The present study with very reliable vaccine history information indicates a beneficial effect of BCG vaccination on the risk of lymphomas....

    Despite the worldwide eradication of smallpox in 1979, the potential bioterrorism threat from variola virus and the ongoing use of vaccinia virus (VACV) as a vector for vaccine development argue for continued research on VACV. In China, the VACV Tiantan strain (TT) was used in the smallpox eradication campaign. Its progeny strain is currently being used to develop a human immunodeficiency virus (HIV) vaccine. Here we sequenced the full genomes of five TT clones isolated by plaque purification from the TT (752-1) viral stock. Phylogenetic analysis with other commonly used VACV strains showed that TT (752-1) and its clones clustered and exhibited higher sequence diversity than that found in Dryvax clones. The ∼190 kbp genomes of TT appeared to encode 273 open reading frames (ORFs). ORFs located in the middle of the genome were more conserved than those located at the two termini, where many virulence and immunomodulation associated genes reside. Several patterns of nucleotide changes including point mutations, insertions and deletions were identified. The polymorphisms in seven virulence-associated proteins and six immunomodulation-related proteins were analyzed. We also investigated the neuro- and skin- virulence of TT clones in mice and rabbits, respectively. The TT clones exhibited significantly less virulence than the New York City Board of Health (NYCBH) strain, as evidenced by less extensive weight loss and morbidity in mice as well as produced smaller skin lesions and lower incidence of putrescence in rabbits. The complete genome sequences, ORF annotations, and phenotypic diversity yielded from this study aid our understanding of the Chinese historic TT strain and are useful for HIV vaccine projects employing TT as a vector.

  8. Adverse events post smallpox-vaccination: insights from tail scarification infection in mice with Vaccinia virus.

    Full Text Available Adverse events upon smallpox vaccination with fully-replicative strains of Vaccinia virus (VACV comprise an array of clinical manifestations that occur primarily in immunocompromised patients leading to significant host morbidity/mortality. The expansion of immune-suppressed populations and the possible release of Variola virus as a bioterrorist act have given rise to concerns over vaccination complications should more widespread vaccination be reinitiated. Our goal was to evaluate the components of the host immune system that are sufficient to prevent morbidity/mortality in a murine model of tail scarification, which mimics immunological and clinical features of smallpox vaccination in humans. Infection of C57BL/6 wild-type mice led to a strictly localized infection, with complete viral clearance by day 28 p.i. On the other hand, infection of T and B-cell deficient mice (Rag1(-/- produced a severe disease, with uncontrolled viral replication at the inoculation site and dissemination to internal organs. Infection of B-cell deficient animals (µMT produced no mortality. However, viral clearance in µMT animals was delayed compared to WT animals, with detectable viral titers in tail and internal organs late in infection. Treatment of Rag1(-/- with rabbit hyperimmune anti-vaccinia serum had a subtle effect on the morbidity/mortality of this strain, but it was effective in reduce viral titers in ovaries. Finally, NUDE athymic mice showed a similar outcome of infection as Rag1(-/-, and passive transfer of WT T cells to Rag1(-/- animals proved fully effective in preventing morbidity/mortality. These results strongly suggest that both T and B cells are important in the immune response to primary VACV infection in mice, and that T-cells are required to control the infection at the inoculation site and providing help for B-cells to produce antibodies, which help to prevent viral dissemination. These insights might prove helpful to better identify

    Spain encouraged, during the Bourbon dynasty, the formation of scientific expeditions, among which was the Royal Philanthropic Vaccine Expedition, an example of biopolitics applied by the state in order to protect health. The expedition went all over the world, using children as a reservoir to transport the vaccine fluid. Francisco Xavier Balmis established a human chain that arm-to-arm materialized the success of the mission. The characteristics and difficulties which children had to pass through and their contribution to the spread of the smallpox vaccine are analyzed.

    The National Smallpox Vaccine in Pregnancy Registry (NSVIPR) actively follows women inadvertently vaccinated with smallpox vaccine during or shortly before pregnancy to evaluate their reproductive health outcomes. Approximately 65% of NSVIPR participants also inadvertently received Anthrax Vaccine Adsorbed (AVA) while pregnant, providing a ready opportunity to evaluate pregnancy and infant health outcomes among these women. AVA-exposed pregnancies were ascertained using NSVIPR and electronic healthcare data. Rates of pregnancy loss and infant health outcomes, including major birth defects, were compared between AVA-exposed and AVA-unexposed pregnancies. Analyses included AVA-exposed and AVA-unexposed pregnant women who also received smallpox vaccine 28 days prior to or during pregnancy. Rates of adverse outcomes among the AVA-exposed group were similar to or lower than expected when compared with published reference rates and the AVA-unexposed population. The findings provide reassurance of the safety of AVA when inadvertently received by a relatively young and healthy population during pregnancy. PMID:26049005

    In the German Reich, smallpox vaccinations were organized by the state. A mandatory vaccination throughout the empire was introduced in 1874, which was continued in the Federal Republic of Germany (FRG) and the German Democratic Republic (GDR) until 1982/1983. From 1935, health departments were responsible for vaccinations. In the GDR, immunization was tightly organized: The state made great efforts to achieve high vaccination rates. Responsibilities were clearly defined at all levels and for all ages. While vaccination was initially mandatory only at the regional level, the legally mandated immunization schedule later contained compulsory vaccinations, e.g., against measles. In the beginning there were mandatory vaccinations in the FRG at the Länder level. Since 1961, the Federal Epidemics Act has impeded obligatory vaccinations. Instead, voluntary vaccinations based on recommendations were stressed. Since the 1980s, vaccinations have been shifted from the public health service sector to office-based physicians. Today, public health authorities offer mainly supplementary vaccinations. In 2007, protective immunizations were introduced as compulsory benefits of the statutory health insurance (SHI). Recently, the German federal states developed a National Vaccination Plan to support immunization strategies.

Vaccinia [smallpox] vaccine: recommendations of the Advisory Committee on Immunization Practices [ACIP], 2001. MMWR 2001;50[No. RR-10]:1-25). This supplemental report provides recommendations for using smallpox vaccine in the pre-event vaccination program in the United States. To facilitate preparedness and response, smallpox vaccination is recommended for persons designated by public health authorities to conduct investigation and follow-up of initial smallpox cases that might necessitate direct patient contact. ACIP recommends that each state and territory establish and maintain > or = 1 smallpox response team. ACIP and the Healthcare Infection Control Practices Advisory Committee (HICPAC) recommend that each acute-care hospital identify health-care workers who can be vaccinated and trained to provide direct medical care for the first smallpox patients requiring hospital admission and to evaluate and manage patients who are suspected as having smallpox. When feasible, the first-stage vaccination program should include previously vaccinated health-care personnel to decrease the potential for adverse events. Additionally persons administering smallpox vaccine in this pre-event vaccination program should be vaccinated. Smallpox vaccine is administered by using the multiple-puncture technique with a bifurcated needle, packaged with the vaccine and diluent. According to the product labeling, 2-3 punctures are recommended for primary vaccination and 15 punctures for revaccination. A trace of blood should appear at the vaccination site after 15-20 seconds; if no trace of blood is visible, an additional 3 insertions should be made by using the same bifurcated needle without reinserting the needle into the vaccine vial. If no evidence of vaccine take is apparent after 7 days, the person can be vaccinated again. Optimal infection-control practices and appropriate

    One of the preconditions for the spread of vaccination against pox diseases was making vaccination available. The first vaccinations were carried out using original cowpox lymph sent by Jenner. For further vaccinations the vaccine was extracted from the blisters of those who had been successfully inoculated. In order to provide vaccine continuously six vaccine centres were set up in 1804 in the following cities: Pest, Buda, Kassa, Gyula, Pozsony and Zágráb (Croatia). Detailed information is available only about the centre in Pest which operated in Rókus Hospital under the leadership of the hospital director András Bossányi. Besides regular vaccination they also provided vaccine for the countryside. From 1824 the vaccine was relocated to the medical faculty of the university in Pest and Ferenc Gebhardt, an instructor of surgeons, became its head. The centre operated in the building of the medical faculty and vaccinations were given on Thursdays and Sundays. After the retirement of Gebhardt in 1860, the centre was taken over by the dermatologist Ferenc Poor for a short time, then by Ignác Semmelweis. From 1863 Gergely Patrubány was responsible for managing the centre. In 1874 the central vaccine institution moved to the Hospital for Poor Children in Pest where it was led first by Lázár Wittman, then by Géza Hainiss. In the 1880s private institutions appeared, the best known were Dani Pécsi's centre in Pest and Béla Intze's one in Tirgu Lapus (Romania). Between 1873 an 1889 András Kreichel ran a vaccine centre in Nálepkovo (Slovakia).

    Natural orthopoxvirus outbreaks such as vaccinia, cowpox, cattlepox and buffalopox continue to cause morbidity in the human population. Monkeypox virus remains a significant agent of morbidity and mortality in Africa. Furthermore, monkeypox virus's broad host-range and expanding environs make it of particular concern as an emerging human pathogen. Monkeypox virus and variola virus (the etiological agent of smallpox) are both potential agents of bioterrorism. The first line response to orthopoxvirus disease is through vaccination with first-generation and second-generation vaccines, such as Dryvax and ACAM2000. Although these vaccines provide excellent protection, their widespread use is impeded by the high level of adverse events associated with vaccination using live, attenuated virus. It is possible that vaccines could be used in combination with antiviral drugs to reduce the incidence and severity of vaccine-associated adverse events, or as a preventive in individuals with uncertain exposure status or contraindication to vaccination. We have used the intranasal mousepox (ectromelia) model to evaluate the efficacy of vaccination with Dryvax or ACAM2000 in conjunction with treatment using the broad spectrum antiviral, brincidofovir (BCV, CMX001). We found that co-treatment with BCV reduced the severity of vaccination-associated lesion development. Although the immune response to vaccination was quantifiably attenuated, vaccination combined with BCV treatment did not alter the development of full protective immunity, even when administered two days following ectromelia challenge. Studies with a non-replicating vaccine, ACAM3000 (MVA), confirmed that BCV's mechanism of attenuating the immune response following vaccination with live virus was, as expected, by limiting viral replication and not through inhibition of the immune system. These studies suggest that, in the setting of post-exposure prophylaxis, co-administration of BCV with vaccination should be considered

    The possible bioterrorism threat using the variola virus, the causative agent of smallpox, has promoted us to further investigate the immunogenicity profiles of existing vaccines. Here, we study for the first time the immunogenicity profile of a replication-competent smallpox vaccine (vaccinia Tiantan, VTT strain) for inducing neutralizing antibodies (Nabs) through mucosal vaccination, which is noninvasive and has a critical implication for massive vaccination programs. Four different routes of vaccination were tested in parallel including intramuscular (i.m.), intranasal (i.n.), oral (i.o.), and subcutaneous (s.c.) inoculations in mice. We found that one time vaccination with an optimal dose of VTT was able to induce anti-VTT Nabs via each of the four routes. Higher levels of antiviral Nabs, however, were induced via the i.n. and i.o. inoculations when compared with the i.m. and s.c. routes. Moreover, the i.n. and i.o. vaccinations also induced higher sustained levels of Nabs overtime, which conferred better protections against homologous or alternating mucosal routes of viral challenges six months post vaccination. The VTT-induced immunity via all four routes, however, was partially effective against the intramuscular viral challenge. Our data have implications for understanding the potential application of mucosal smallpox vaccination and for developing VTT-based vaccines to overcome preexisting antivaccinia immunity.

    The U.S. Department of Defense vaccinates personnel deployed to high-risk areas with the vaccinia virus (VACV)-based smallpox vaccine. Autoinoculations and secondary and tertiary transmissions due to VACV shedding from the vaccination site continue to occur despite education of vaccinees on the risks of such infections. The objectives of this study were to investigate, in naïve smallpox vaccinees, (a) whether the vaccination site can remain contagious after the scab separates and (b) whether the application of povidone iodine ointment (PIO) to the vaccination site inactivates VACV without affecting the immune response. These objectives were tested in 60 individuals scheduled to receive smallpox vaccine. Thirty individuals (control) did not receive PIO; 30 subjects (treatment) received PIO starting on post-vaccination day 7. Counter to current dogma, this study showed that VACV continues to shed from the vaccination site after the scab separates. Overall viral shedding levels in the PIO group were significantly lower than those in the control group (p=0.0045), and PIO significantly reduced the duration of viral shedding (median duration 14.5 days and 21 days in the PIO and control groups, respectively; p=0.0444). At least 10% of control subjects continued to shed VACV at day 28, and 3.4% continued to shed the virus at day 42. PIO reduced the proportion of subjects shedding virus from the vaccination site from day 8 until days 21-23 compared with control subjects. Groups did not differ significantly in the proportion of subjects mounting an immune response, as measured by neutralizing antibodies, IgM, IgG, and interferon-gamma enzyme-linked immunospot assay. When applied to the vaccination site starting on day 7, PIO reduced viral shedding without altering the immune response. The use of PIO in addition to a semipermeable dressing may reduce the rates of autoinoculation and contact transmission originating from the vaccination site in smallpox-vaccinated individuals.

    Dryvax (Wyeth Laboratories, Inc., Marietta, PA) is representative of the vaccinia virus preparations that were previously used for preventing smallpox. While Dryvax was highly effective, the national supply stocks were depleted, and there were manufacturing concerns regarding sterility and the clonal heterogeneity of the vaccine. ACAM2000 (Acambis, Inc./Sanofi-Pasteur Biologics Co., Cambridge, MA), a single-plaque-purified vaccinia virus derivative of Dryvax, recently replaced the polyclonal smallpox vaccine for use in the United States. A substantial amount of sequence heterogeneity exists within the polyclonal proteome of Dryvax, including proteins that are missing from ACAM2000. Reasoning that a detailed comparison of antibody responses to the polyclonal and monoclonal vaccines may be useful for identifying unique properties of each antibody response, we utilized a protein microarray comprised of approximately 94% of the vaccinia poxvirus proteome (245 proteins) to measure protein-specific antibody responses of 71 individuals receiving a single vaccination with ACAM2000 or Dryvax. We observed robust antibody responses to 21 poxvirus proteins in vaccinated individuals, including 11 proteins that distinguished Dryvax responses from ACAM2000. Analysis of protein sequences from Dryvax clones revealed amino acid level differences in these 11 antigenic proteins and suggested that sequence variation and clonal heterogeneity may contribute to the observed differences between Dryvax and ACAM2000 antibody responses.

    Decades after public health interventions - including pre- and post-exposure vaccination - were used to eradicate smallpox, zoonotic orthopoxvirus outbreaks and the potential threat of a release of variola virus remain public health concerns. Routine prophylactic smallpox vaccination of the public ceased worldwide in 1980, and the adverse event rate associated with the currently licensed live vaccinia virus vaccine makes reinstatement of policies recommending routine pre-exposure vaccination unlikely in the absence of an orthopoxvirus outbreak. Consequently, licensing of safer vaccines and therapeutics that can be used post-orthopoxvirus exposure is necessary to protect the global population from these threats. Variola virus is a solely human pathogen that does not naturally infect any other known animal species. Therefore, the use of surrogate viruses in animal models of orthopoxvirus infection is important for the development of novel vaccines and therapeutics. Major complications involved with the use of surrogate models include both the absence of a model that accurately mimics all aspects of human smallpox disease and a lack of reproducibility across model species. These complications limit our ability to model post-exposure vaccination with newer vaccines for application to human orthopoxvirus outbreaks. This review seeks to (1) summarize conclusions about the efficacy of post-exposure smallpox vaccination from historic epidemiological reports and modern animal studies; (2) identify data gaps in these studies; and (3) summarize the clinical features of orthopoxvirus-associated infections in various animal models to identify those models that are most useful for post-exposure vaccination studies. The ultimate purpose of this review is to provide observations and comments regarding available model systems and data gaps for use in improving post-exposure medical countermeasures against orthopoxviruses.

Additionally, 31 SPX-vaccinees without specific cardiac symptoms were found to have over 2-fold increases in cTnT (>99th percentile from baseline (pre-SPX during the window of risk for clinical myocarditis/pericarditis and meeting a proposed case definition for possible subclinical myocarditis. This rate is 60-times higher than the incidence rate of overt clinical cases. No clinical or possible subclinical myocarditis cases were identified in the TIV-vaccinated group.Passive surveillance significantly underestimates the true incidence of myocarditis/pericarditis after smallpox immunization.

    Full Text Available Abstract Background Vaccinia virus (VACV-DUKE was isolated from a lesion on a 54 year old female who presented to a doctor at the Duke University Medical Center. She was diagnosed with progressive vaccinia and treated with vaccinia immune globulin. The availability of the VACV-DUKE genome sequence permits a first time genomic comparison of a VACV isolate associated with a smallpox vaccine complication with the sequence of culture-derived clonal isolates of the Dryvax vaccine. Results This study showed that VACV-DUKE is most similar to VACV-ACAM2000 and CLONE3, two VACV clones isolated from the Dryvax® vaccine stock confirming VACV-DUKE as an isolate from Dryvax®. However, VACV-DUKE is unique because it is, to date, the only Dryvax® clone isolated from a patient experiencing a vaccine-associated complication. The 199,960 bp VACV-DUKE genome encodes 225 open reading frames, including 178 intact genes and 47 gene fragments. Between VACV-DUKE and the other Dryvax® isolates, the major genomic differences are in fragmentation of the ankyrin-like, and kelch-like genes, presence of a full-length Interferon-α/β receptor gene, and the absence of a duplication of 12 ORFs in the inverted terminal repeat. Excluding this region, the DNA sequence of VACV-DUKE differs from the other two Dryvax® isolates by less than 0.4%. DNA sequencing also indicated that there was little heterogeneity in the sample, supporting the hypothesis that virus from an individual lesion is clonal in origin despite the fact that the vaccine is a mixed population. Conclusion Virus in lesions that result from progressive vaccinia following vaccination with Dryvax are likely clonal in origin. The genomic sequence of VACV-DUKE is overall very similar to that of Dryvax® cell culture-derived clonal isolates. Furthermore, with the sequences of multiple clones from Dryvax® we can begin to appreciate the diversity of the viral population in the smallpox vaccine.

  4. GM-CSF production allows the identification of immunoprevalent antigens recognized by human CD4+ T cells following smallpox vaccination.

    Directory of Open Access Journals (Sweden)

    Valeria Judkowski

    Full Text Available The threat of bioterrorism with smallpox and the broad use of vaccinia vectors for other vaccines have led to the resurgence in the study of vaccinia immunological memory. The importance of the role of CD4+ T cells in the control of vaccinia infection is well known. However, more CD8+ than CD4+ T cell epitopes recognized by human subjects immunized with vaccinia virus have been reported. This could be, in part, due to the fact that most of the studies that have identified human CD4+ specific protein-derived fragments or peptides have used IFN-γ production to evaluate vaccinia specific T cell responses. Based on these findings, we reasoned that analyzing a large panel of cytokines would permit us to generate a more complete analysis of the CD4 T cell responses. The results presented provide clear evidence that TNF-α is an excellent readout of vaccinia specificity and that other cytokines such as GM-CSF can be used to evaluate the reactivity of CD4+ T cells in response to vaccinia antigens. Furthermore, using these cytokines as readout of vaccinia specificity, we present the identification of novel peptides from immunoprevalent vaccinia proteins recognized by CD4+ T cells derived from smallpox vaccinated human subjects. In conclusion, we describe a "T cell-driven" methodology that can be implemented to determine the specificity of the T cell response upon vaccination or infection. Together, the single pathogen in vitro stimulation, the selection of CD4+ T cells specific to the pathogen by limiting dilution, the evaluation of pathogen specificity by detecting multiple cytokines, and the screening of the clones with synthetic combinatorial libraries, constitutes a novel and valuable approach for the elucidation of human CD4+ T cell specificity in response to large pathogens.

    IMVAMUNE® is a Modified Vaccinia Ankara-based virus that is being developed as a safer 3rd generation smallpox vaccine. In order to determine the optimal dose for further development, a double-blind, randomized Phase II trial was performed testing three different doses of IMVAMUNE® in 164 healthy volunteers. All three IMVAMUNE® doses displayed a favourable safety profile, with local reactions as the most frequent observation. The 1×108 TCID50 IMVAMUNE® dose induced a total antibody response in 94% of the subjects following the first vaccination and the highest peak seroconversion rates by ELISA (100%) and PRNT (71%). This IMVAMUNE® dose was considered to be optimal for the further clinical development of this highly attenuated poxvirus as a safer smallpox vaccine. PMID:19944151

    From 1804 to 1974, the colonial Dutch East Indies government and the postcolonial Indonesian state attempted to tackle the problem of smallpox. The vaccination efforts in the colonial era virtually eliminated smallpox by 1940. Unfortunately, as a consequence of the war smallpox was reintroduced into the archipelago in 1947. Indonesia finally succeeded in eradicating smallpox in 1974 through campaigns of mass vaccination and surveillance. In the last few years of the fight against smallpox, a detection system was set up in order to have every suspected case of smallpox isolated and investigated by the health authorities until verified in the government laboratory at Bandung. This paper looks at the impact of the archipelagic nature of Indonesia on the smallpox eradication campaigns. PMID:20973337

    Smallpox infection was often more severe in pregnant women than in non-pregnant women or in men, regardless of vaccination status. Women with smallpox infection during pregnancy have higher rates of abortions, stillbirths, and preterm deliveries than women without the disease. Pregnant women have high incidences of hemorrhagic-type and flat-type smallpox, which are associated with extremely high fatality rates. Although smallpox was eradicated in the late 1970s, current international concern exists regarding the potential use of smallpox virus as an agent for bioterrorism. This manuscript reviews clinical aspects of smallpox, smallpox immunization, and outcomes in pregnant women.

    Full Text Available Orthopoxviruses remain a threat as biological weapons and zoonoses. The licensed live-virus vaccine is associated with serious health risks, making its general usage unacceptable. Attenuated vaccines are being developed as alternatives, the most advanced of which is modified-vaccinia virus Ankara (MVA. We previously developed a gene-based vaccine, termed 4pox, which targets four orthopoxvirus antigens, A33, B5, A27 and L1. This vaccine protects mice and non-human primates from lethal orthopoxvirus disease. Here, we investigated the capacity of the molecular adjuvants GM-CSF and Escherichia coli heat-labile enterotoxin (LT to enhance the efficacy of the 4pox gene-based vaccine. Both adjuvants significantly increased protective antibody responses in mice. We directly compared the 4pox plus LT vaccine against MVA in a monkeypox virus (MPXV nonhuman primate (NHP challenge model. NHPs were vaccinated twice with MVA by intramuscular injection or the 4pox/LT vaccine delivered using a disposable gene gun device. As a positive control, one NHP was vaccinated with ACAM2000. NHPs vaccinated with each vaccine developed anti-orthopoxvirus antibody responses, including those against the 4pox antigens. After MPXV intravenous challenge, all control NHPs developed severe disease, while the ACAM2000 vaccinated animal was well protected. All NHPs vaccinated with MVA were protected from lethality, but three of five developed severe disease and all animals shed virus. All five NHPs vaccinated with 4pox/LT survived and only one developed severe disease. None of the 4pox/LT-vaccinated animals shed virus. Our findings show, for the first time, that a subunit orthopoxvirus vaccine delivered by the same schedule can provide a degree of protection at least as high as that of MVA.

    The therapeutic efficacies of smallpox vaccine ACAM2000 and antiviral tecovirimat given alone or in combination starting on day 3 postinfection were compared in a cynomolgus macaque model of lethal monkeypox virus infection. Postexposure administration of ACAM2000 alone did not provide any protection against severe monkeypox disease or mortality. In contrast, postexposure treatment with tecovirimat alone or in combination with ACAM2000 provided full protection. Additionally, tecovirimat treatment delayed until day 4, 5, or 6 postinfection was 83% (days 4 and 5) or 50% (day 6) effective.

    On June 25, 2015, the Advisory Committee on Immunization Practices (ACIP) recommended routine vaccination with live smallpox (vaccinia) vaccine (ACAM2000) for laboratory personnel who directly handle 1) cultures or 2) animals contaminated or infected with replication-competent vaccinia virus, recombinant vaccinia viruses derived from replication-competent vaccinia strains (i.e., those that are capable of causing clinical infection and producing infectious virus in humans), or other orthopoxviruses that infect humans (e.g., monkeypox, cowpox, and variola) (recommendation category: A, evidence type 2 [Box]). Health care personnel (e.g., physicians and nurses) who currently treat or anticipate treating patients with vaccinia virus infections and whose contact with replication-competent vaccinia viruses is limited to contaminated materials (e.g., dressings) and persons administering ACAM2000 smallpox vaccine who adhere to appropriate infection prevention measures can be offered vaccination with ACAM2000 (recommendation category: B, evidence type 2 [Box]). These revised recommendations update the previous ACIP recommendations for nonemergency use of vaccinia virus smallpox vaccine for laboratory and health care personnel at risk for occupational exposure to orthopoxviruses (1). Since 2001, when the previous ACIP recommendations were developed, ACAM2000 has replaced Dryvax as the only smallpox vaccine licensed by the U.S. Food and Drug Administration (FDA) and available for use in the United States (2). These recommendations contain information on ACAM2000 and its use in laboratory and health care personnel at risk for occupational exposure to orthopoxviruses.

  15. Proteomic basis of the antibody response to monkeypox virus infection examined in cynomolgus macaques and a comparison to human smallpox vaccination.

    Sarah Keasey

    Full Text Available Monkeypox is a zoonotic viral disease that occurs primarily in Central and West Africa. A recent outbreak in the United States heightened public health concerns for susceptible human populations. Vaccinating with vaccinia virus to prevent smallpox is also effective for monkeypox due to a high degree of sequence conservation. Yet, the identity of antigens within the monkeypox virus proteome contributing to immune responses has not been described in detail. We compared antibody responses to monkeypox virus infection and human smallpox vaccination by using a protein microarray covering 92-95% (166-192 proteins of representative proteomes from monkeypox viral clades of Central and West Africa, including 92% coverage (250 proteins of the vaccinia virus proteome as a reference orthopox vaccine. All viral gene clones were verified by sequencing and purified recombinant proteins were used to construct the microarray. Serum IgG of cynomolgus macaques that recovered from monkeypox recognized at least 23 separate proteins within the orthopox proteome, while only 14 of these proteins were recognized by IgG from vaccinated humans. There were 12 of 14 antigens detected by sera of human vaccinees that were also recognized by IgG from convalescent macaques. The greatest level of IgG binding for macaques occurred with the structural proteins F13L and A33R, and the membrane scaffold protein D13L. Significant IgM responses directed towards A44R, F13L and A33R of monkeypox virus were detected before onset of clinical symptoms in macaques. Thus, antibodies from vaccination recognized a small number of proteins shared with pathogenic virus strains, while recovery from infection also involved humoral responses to antigens uniquely recognized within the monkeypox virus proteome.

    Although many diseases and traits show large heritability, few genetic variants have been found to strongly separate phenotype groups by genotype. Complex regulatory networks of variants and expression of multiple genes lead to small individual-variant effects and difficulty replicating the effect of any single variant in an affected pathway. Interaction network modeling of GWAS identifies effects ignored by univariate models, but population differences may still cause specific genes to not replicate. Integrative network models may help detect indirect effects of variants in the underlying biological pathway. In this study, we used gene-level functional interaction information from the Integrative Multi-species Prediction (IMP) tool to reveal important genes associated with a complex phenotype through evidence from epistasis networks and pathway enrichment. We test this method for augmenting variant-based network analyses with functional interactions by applying it to a smallpox vaccine immune response GWAS. The integrative analysis spotlights the role of genes related to retinoid X receptor alpha (RXRA), which has been implicated in a previous epistasis network analysis of smallpox vaccine.

  17. Critical role of perforin-dependent CD8+ T cell immunity for rapid protective vaccination in a murine model for human smallpox.

    Directory of Open Access Journals (Sweden)

    Melanie Kremer

    Full Text Available Vaccination is highly effective in preventing various infectious diseases, whereas the constant threat of new emerging pathogens necessitates the development of innovative vaccination principles that also confer rapid protection in a case of emergency. Although increasing evidence points to T cell immunity playing a critical role in vaccination against viral diseases, vaccine efficacy is mostly associated with the induction of antibody responses. Here we analyze the immunological mechanism(s of rapidly protective vaccinia virus immunization using mousepox as surrogate model for human smallpox. We found that fast protection against lethal systemic poxvirus disease solely depended on CD4 and CD8 T cell responses induced by vaccination with highly attenuated modified vaccinia virus Ankara (MVA or conventional vaccinia virus. Of note, CD4 T cells were critically required to allow for MVA induced CD8 T cell expansion and perforin-mediated cytotoxicity was a key mechanism of MVA induced protection. In contrast, selected components of the innate immune system and B cell-mediated responses were fully dispensable for prevention of fatal disease by immunization given two days before challenge. In conclusion, our data clearly demonstrate that perforin-dependent CD8 T cell immunity plays a key role in MVA conferred short term protection against lethal mousepox. Rapid induction of T cell immunity might serve as a new paradigm for treatments that need to fit into a scenario of protective emergency vaccination.

  18. Extent of Systemic Spread Determines CD8+ T Cell Immunodominance for Laboratory Strains, Smallpox Vaccines, and Zoonotic Isolates of Vaccinia Virus.

    CD8(+) T cells that recognize virus-derived peptides presented on MHC class I are vital antiviral effectors. Such peptides presented by any given virus vary greatly in immunogenicity, allowing them to be ranked in an immunodominance hierarchy. However, the full range of parameters that determine immunodominance and the underlying mechanisms remain unknown. In this study, we show across a range of vaccinia virus strains, including the current clonal smallpox vaccine, that the ability of a strain to spread systemically correlated with reduced immunodominance. Reduction in immunodominance was observed both in the lymphoid system and at the primary site of infection. Mechanistically, reduced immunodominance was associated with more robust priming and especially priming in the spleen. Finally, we show this is not just a property of vaccine and laboratory strains of virus, because an association between virulence and immunodominance was also observed in isolates from an outbreak of zoonotic vaccinia virus that occurred in Brazil.

    Logistics, defined as "the time-related positioning of resources" was critical to the implementation of the smallpox eradication strategy of surveillance and containment. Logistical challenges in the smallpox programme included vaccine delivery, supplies, staffing, vehicle maintenance, and financing. Ensuring mobility was essential as health workers had to travel to outbreaks to contain them. Three examples illustrate a range of logistic challenges which required imagination and innovation. Standard price lists were developed to expedite vehicle maintenance and repair in Bihar, India. Innovative staffing ensured an adequate infrastructure for vehicle maintenance in Bangladesh. The use of disaster relief mechanisms in Somalia provided airlifts, vehicles and funding within 27 days of their initiation. In contrast the Expanded Programme on Immunization (EPI) faces more complex logistical challenges.

    The smallpox virus is a high-priority, Category-A agent that poses a global, terrorism security risk because it: (1) easily can be disseminated and transmitted from person to person; (2) results in high mortality rates and has the potential for a major public health impact; (3) might cause public panic and social disruption; and (4) requires special action for public health preparedness. In recognition of this risk, the Los Angeles County Department of Health Services (LAC-DHS) developed the Smallpox Preparedness, Response, and Recovery Plan for LAC to prepare for the possibility of an outbreak of smallpox. A unique feature of the LAC-DHS plan is its explicit use of the Standardized Emergency Management System (SEMS) framework for detailing the functions needed to respond to a smallpox emergency. The SEMS includes the Incident Command System (ICS) structure (management, operations, planning/intelligence, logistics, and finance/administration), the mutual-aid system, and the multi/interagency coordination required during a smallpox emergency. Management for incident command includes setting objectives and priorities, information (risk communications), safety, and liaison. Operations includes control and containment of a smallpox outbreak including ring vaccination, mass vaccination, adverse events monitoring and assessment, management of confirmed and suspected smallpox cases, contact tracing, active surveillance teams and enhanced hospital-based surveillance, and decontamination. Planning/intelligence functions include developing the incident action plan, epidemiological investigation and analysis of smallpox cases, and epidemiological assessment of the vaccination coverage status of populations at risk. Logistics functions include receiving, handling, inventorying, and distributing smallpox vaccine and vaccination clinic supplies; personnel; transportation; communications; and health care of personnel. Finally, finance/administration functions include monitoring

Adverse events, cardiac parameters, and the development of vaccinia virus humoral immune responses were monitored.The overall safety of the vaccine was similar in both groups. Adverse events affecting skin were experienced significantly more often in subjects with AD, but the majority of these events were mild to moderate in intensity. Seroconversion rates and geometric mean titers for total and neutralizing vaccinia-specific antibodies in the AD group were non-inferior compared to the healthy subjects.The size of the study population limited the detection of serious adverse events occurring at a frequency less than 1%.MVA has a favorable safety profile and the ability to elicit vaccinia-specific immune responses in subjects with AD.ClinicalTrials.gov NCT00316602.

    A method for assaying neutralizing antibody against variola virus was established by focus counting on HeLa cell cultures. The ND(50) titre, i.e., the serum dilution endpoint to give a 50% reduction in the number of foci, was determined with excellent reproducibility.Groups of students 19-20 years of age were revaccinated by the multiple pressure method with serial 10-fold dilutions of a smallpox vaccine and their neutralizing antibody response was assayed by the focus counting assay system and was related to the local skin reactions on the seventh day after inoculation and to the potency of the vaccine administered. There was a significant rise in the antibody level even after inoculation with a vaccine whose potency was as low as 1.3 x 10(5) pock-forming units/ml. In general, the rise in the log antibody level was proportional to the diameter of the reddening, but a significant rise was found among individuals who had no detectable skin reaction. The skin reaction was greater among individuals with a lower initial antibody level when the vaccine administered had a potency lower than 1.3 x 10(6) pock-forming units/ml.

    Full Text Available The current live vaccinia virus vaccine used in the prevention of smallpox is contraindicated for millions of immune-compromised individuals. Although vaccination with the current smallpox vaccine produces protective immunity, it might result in mild to serious health complications for some vaccinees. Thus, there is a critical need for the production of a safe virus-free vaccine against smallpox that is available to everyone. For that reason, we investigated the impact of imiquimod and resiquimod (Toll-like receptors agonists, and the codon-usage optimization of the vaccinia virus A27L gene in the enhancement of the immune response, with intent of producing a safe, virus-free DNA vaccine coding for the A27 vaccinia virus protein.We analyzed the cellular-immune response by measuring the IFN-γ production of splenocytes by ELISPOT, the humoral-immune responses measuring total IgG and IgG2a/IgG1 ratios by ELISA, and the TH1 and TH2 cytokine profiles by ELISA, in mice immunized with our vaccine formulation.The proposed vaccine formulation enhanced the A27L vaccine-mediated production of IFN-γ on mouse spleens, and increased the humoral immunity with a TH1-biased response. Also, our vaccine induced a TH1 cytokine milieu, which is important against viral infections.These results support the efforts to find a new mechanism to enhance an immune response against smallpox, through the implementation of a safe, virus-free DNA vaccination platform.

    Full Text Available This article seeks to understand the discursive context of the cessation of routine smallpox vaccination in the United States in the early 1970s. The United States has a long tradition of opposition to compulsory smallpox vaccination, usually expressed in terms of concerns about personal liberties, the extent of state authority, and challenges to the hegemony of orthodox biomedicine. The practice of routine smallpox vaccination continued in the United States until its termination in the 1970s, following a 1971 recommendation against the practice issued by the United States Public Health Service. This history investigates the ways in which opposition to compulsory smallpox vaccination in the 1960s and 70s was articulated and understood by contemporaries through an analysis of the rhetoric used in leading medical journals and popular newspapers. It finds that this ultimately successful movement to end routine smallpox vaccination drew upon the language of biomedical authority rather than political protest.Este artigo procura entender o contexto discursivo da cessação da vacinação de rotina contra varíola nos Estados Unidos no início dos anos 70.

    Smallpox eradication is considered to be one of the most remarkable accomplishments of the 20th century. Lessons learned from the campaign during the 1960s and 1970s in the Democratic Republic of Congo (DRC) can provide important information for the development of other eradication programs including polio. The DRC is the third largest country in Africa; the population suffers from extreme poverty, deteriorating infrastructure and health systems, and long periods of civil strife. Despite these challenges, DRC's smallpox eradication campaign was successful, eradicating smallpox only 41 months after initiation. DRC had been polio free since 2001; however, in 2006, imported cases were identified in the country. Polio transmission has since been re-established and DRC now has the second greatest number of reported polio cases in the world. Challenges which existed during the smallpox campaign in DRC are still present today; additionally, the polio vaccine itself poses unique challenges which include requiring multiple doses to confer immunity. In the fight against polio in DRC, it will be important to draw from the smallpox eradication experience. A number of important themes emerged during the campaign that could be beneficial to eradicating polio and future eradication programs that may follow. During the smallpox campaign, a standard vaccination program was implemented, surveillance was intensified, and there were strong collaborative programs with community involvement. These successful elements of the smallpox campaign should be adapted and applied in DRC in polio eradication programs. PMID:22188930

    Efficacy of candidate DNA-vaccines based on the variola virus natural gene A30L and artificial gene A30Lopt with modified codon usage, optimized for expression in mammalian cells, was tested. The groups of mice were intracutaneously immunized three times with three-week intervals with candidate DNA-vaccines: pcDNA_A30L or pcDNA_A30Lopt, and in three weeks after the last immunization all mice in the groups were intraperitoneally infected by the ectromelia virus K1 strain in 10 LD50 dose for the estimation of protection. It was shown that the DNA-vaccines based on natural gene A30L and codon-optimized gene A30Lopt elicited virus, thereby neutralizing the antibody response and protected mice from lethal intraperitoneal challenge with the ectromelia virus with lack of statistically significant difference.

    SIGA Technologies, Inc. is a small biotech company committed to developing novel products for the prevention and treatment of serious viral diseases, with an emphasis on products to combat outbreaks that could result from bioterrorism. With government support, SIGA has developed the necessary infrastructure to successfully advance new antiviral drugs from the discovery stage through to licensing. Currently, there is a need to develop safe and effective inhibitors for poxvirus-induced diseases such as smallpox caused by variola, which is a potential biological warfare agent. Likewise emerging zoonotic infections due to cowpox virus and monkeypox virus require the development of effective countermeasures. Tecovirimat, also known as ST-246, has shown efficacy in all small animal and nonhuman primate prophylaxis and therapeutic efficacy models of poxvirus-induced disease tested to date. Phase I clinical trials and new drug application-enabling toxicology studies have been completed with tecovirimat. A phase II clinical study is being run and SIGA has initiated commercial scale-up manufacturing and preparation for the pivotal safety and efficacy studies. SIGA is committed to getting approval for tecovirimat and supplying it to the Strategic National Stockpile, the Department of Defense and global health authorities. PMID:20393639

    Concern over the release of variola virus as an agent of bioterrorism remains high and a rapid vaccination regimen is desirable for use in the event of a confirmed release of virus. A single, high-dose (5×10(8) TCID50) of Bavarian Nordic's IMVAMUNE was tested in a Phase-II clinical trial, in humans, as a substitute for the standard (1×10(8) TCID50), using a 2-dose, 28-days apart regimen. Prior to this clinical trial taking place a Good Laboratory Practice, repeated high-dose, toxicology study was performed using IMVAMUNE, in New Zealand white rabbits and the results are reported here. Male and female rabbits were dosed twice, subcutaneously, with 5×10(8) TCID50 of IMVAMUNE (test) or saline (control), 7-days apart. The clinical condition, body-weight, food consumption, haematology, blood chemistry, immunogenicity, organ-weight, and macroscopic and microscopic pathology were investigated. Haematological investigations indicated changes within the white blood cell profile that were attributed to treatment with IMVAMUNE; these comprised slight increases in neutrophil and monocyte numbers, on study days 1-3 and a marginal increase in lymphocyte numbers on day 10. Macroscopic pathology revealed reddening at the sites of administration and thickened skin in IMVAMUNE, treated animals. After the second dose of IMVAMUNE 9/10 rabbits seroconverted, as detected by antibody ELISA on day 10, by day 21, 10/10 rabbits seroconverted. Treatment-related changes were not detected in other parameters. In conclusion, the subcutaneous injection of 2 high-doses of IMVAMUNE, to rabbits, was well tolerated producing only minor changes at the site of administration. Vaccinia-specific antibodies were raised in IMVAMUNE-vaccinated rabbits only.

    The smallpox antiviral tecovirimat has recently been purchased by the U.S. Strategic National Stockpile. Given significant uncertainty regarding both the contagiousness of smallpox in a contemporary outbreak and the efficiency of a mass vaccination campaign, vaccine prophylaxis alone may be unable to control a smallpox outbreak following a bioterror attack. Here, we present the results of a compartmental epidemiological model that identifies conditions under which tecovirimat is required to curtail the epidemic by exploring how the interaction between contagiousness and prophylaxis coverage of the affected population affects the ability of the public health response to control a large-scale smallpox outbreak. Each parameter value in the model is based on published empirical data. We describe contagiousness parametrically using a novel method of distributing an assumed R-value over the disease course based on the relative rates of daily viral shedding from human and animal studies of cognate orthopoxvirus infections. Our results suggest that vaccination prophylaxis is sufficient to control the outbreak when caused either by a minimally contagious virus or when a very high percentage of the population receives prophylaxis. As vaccination coverage of the affected population decreases below 70%, vaccine prophylaxis alone is progressively less capable of controlling outbreaks, even those caused by a less contagious virus (R0 less than 4). In these scenarios, tecovirimat treatment is required to control the outbreak (total number of cases under an order of magnitude more than the number of initial infections). The first study to determine the relative importance of smallpox prophylaxis and treatment under a range of highly uncertain epidemiological parameters, this work provides public health decision-makers with an evidence-based guide for responding to a large-scale smallpox outbreak.

    2014-12-01

    Smallpox inoculation (variolation) was widely reported in sub-Sahara Africa before, during, and after the colonial era. The infective smallpox materials and techniques used, as well as the anatomical sites for inoculation, varied widely among different ethnic groups. The practice among the Boran and Gabra pastoralists of northern Kenya resembled that which was prevalent in a number of areas of Ethiopia. This is not surprising as the Boran also live in southern Ethiopia, and Gabra herdsmen frequently cross the border into this region. The Boran and Gabra technique for smallpox inoculation consisted of taking infective material from the vesicles or pustules of those with active smallpox, and scraping it into the skin on the dorsum of the lower forearm. Although the intent was to cause a local reaction and at most a mild form of smallpox, severe cases of the disease not infrequently resulted. Also, variolated individuals were capable of infecting others with smallpox, thereby augmenting outbreaks and sustaining them. The limited known reports of smallpox inoculation among the Boran and Gabra are presented in this communication. The expansion of vaccination with effective heat stable vaccines, the development of medical and public health infrastructures, and educational programs all contributed to the eventual disappearance of the practice among the Boran and Gabra.

Observam-se, ao longo deste período, a configuração de políticas de saúde e a criação de organismos estatais direcionados a doenças e ações específicas, o que no caso da varíola somente ocorreu na década de 1960, quando foram criadas a Campanha Nacional contra a Varíola e a Campanha Nacional de Erradicação da Varíola.

    Full Text Available Abstract Background Although an effective measles vaccine has been available for almost 40 years, in 2000 there were about 30 million measles infections worldwide and 777,000 measles-related deaths. The history of smallpox suggests that achieving measles eradication depends on several factors; the biological characteristics of the organism; vaccine technology; surveillance and laboratory identification; effective delivery of vaccination programmes and international commitment to eradication. Discussion Like smallpox, measles virus has several biological characteristics that favour eradication. Humans are the only reservoir for the virus, which causes a visible illness and infection leading to life-long immunity. As the measles virus has only one genetic serotype which is relatively stable over time, the same basic vaccine can be used world-wide. Vaccination provides protection against measles infection for at least 15 years, although efficacy may be reduced due to host factors such as nutritional status. Measles vaccination may also confer other non-specific health benefits leading to reduced mortality. Accurate laboratory identification of measles cases enables enhanced surveillance to support elimination programmes. The "catch-up, keep-up, follow-up" vaccination programme implemented in the Americas has shown that measles elimination is possible using existing technologies. On 17th October 2003 the "Cape Town Measles Declaration" by the World Health Organisation and the United Nations Childrens Fund called on governments to intensify efforts to reduce measles mortality by supporting universal vaccination coverage and the development of more effective vaccination. Summary Although more difficult than for smallpox, recent experience in the Americas suggests that measles eradication is technically feasible. Growing international support to deliver these programmes means that measles, like smallpox, may very well become a curiosity of history.

Apesar da presença de órgãos que visavam à organização e à propagação da vacina no país desde o início do século XIX, identifica-se, pela documentação relativa à saúde pública produzida pelas autoridades provinciais, uma série de fatores de natureza administrativa e cultural que influenciaram negativamente na plena implementação quer da vacina quer da estrutura organizada no período visando à sua difusão. Seguindo as proposições da historiografia dedicada ao tema, discute-se que, apesar da tendência à centralização observada em diferentes esferas da administração no processo de estruturação do Estado Imperial, no âmbito da saúde e, particularmente, no âmbito do serviço de vacinação antivariólica, prevaleceu uma desarticulação entre os diferentes agentes responsáveis pela implementação e o controle desse serviço. Outro aspecto que contribuiu para as dificuldades relativas à implementação desse serviço foi a grande resistência da população em submeter-se à vacina e que pode ser entendida pela análise das percepções sociais construídas sobre a doença e o método da vacinação.This article discusses the impact of smallpox and vaccination practices used against the disease used in the province of Minas Gerais, in Brazil, during the Imperial Period (1822-1889.

    During World War II, nearly all US and Allied troops received yellow fever vaccine. Until May 1942, it was both grown and suspended in human serum. In April 1942, major epidemics of hepatitis occurred in US and Allied troops who had received yellow fever vaccine. A rapid and thorough investigation by the US surgeon general followed, and a directive was issued discontinuing the use of human serum in vaccine production. The large number of cases of hepatitis caused by the administration of this vaccine could have been avoided. Had authorities undertaken a thorough review of the literature, they would have discovered published reports, as early as 1885, of postvaccination epidemics of hepatitis in both men and horses. It would take 4 additional decades of experiments and epidemiological research before viruses of hepatitis A, B, C, D, and E were identified, their modes of transmission understood, and their genomes sequenced.

    Smallpox eradication culminated the most successful antimicrobial campaign in medical history. To characterize further the linear double-stranded DNA genome of the aetiological agent of smallpox, we have determined the entire nucleotide sequence of the highly virulent variola major virus, strain Bangladesh-1975 (VAR-BSH; 186,102 base pairs, 33.7% G + C; Genbank accession number, L22579). Here we highlight features of the molecule and focus on a few of the 187 putative proteins that probably contribute to pathogenicity and virus host-range properties. One hundred and fifty proteins were markedly similar to those of vaccinia virus (smallpox vaccine), for which a complete sequence has been reported for strain Copenhagen (VAC-CPN; 191,636 base pairs, 33.3% G + C). The remaining 37 proteins reflected variola-specific sequences or open reading frame divergences for variant proteins, which are often truncated or elongated compared with their vaccinia counterparts.

    During September 2002, Israel began its current revaccination program against smallpox, targeting previously vaccinated "first responders" among medical and emergency workers. In order to identify the potential strengths and weaknesses of this program and the conditions under which critical decisions were reached, we conducted a SWOT analysis of the current Israeli revaccination program, designed to identify its intrinsic strengths and weaknesses, as well as opportunities for its success and threats against it. SWOT analysis--a practical tool for the study of public health policy decisions and the social and political contexts in which they are reached--revealed clear and substantial strengths and weaknesses of the current smallpox revaccination program, intrinsic to the vaccine itself. A number of threats were identified that may jeopardize the success of the current program, chief among them the appearance of severe complications of vaccination. Our finding of a lack of a generation of knowledge on smallpox vaccination highlights the need for improved physician education and dissipation of misconceptions that are prevalent in the public today.

    1994-01-01

    Smallpox contributed to the death of 300,000 people in Sweden between 1750 and 1800. It was one of the most feared diseases of the time. Most victims were children under the age of 10 years. It is estimated that one out of every ten children died from smallpox. The mortality rate was between 10% and 20% but those who survived faced severe complications. Most common were the disfiguring pockmarks among those previously infected. It turned out that women who had contracted smallpox married much later in life than the healthy. Also, both female and male fertility was lowered by smallpox infection. By the mid 1750s inoculation was introduced in Sweden. This was a preventive method where a mild infection was given by putting smallpox matter into an incision in the skin. Success was restricted to the wealthy, even if the doctors tried to reach the common people. The main reasons were lack of confidence for doctors, medical and epidemiological risks, costs and an ineffective organization. In 1801 Eberhard Zacharias Munch of Rosenschöld performed the first vaccination with cowpox matter in Sweden. In a few years an extensive practise was stabilized, which made the Swedish population one of the best vaccinated in the world. Moreover, a unique registration was compiled which, together with the parish records, makes the country one of the best documented. The main reasons behind the success was previous experiences of inoculation, international influences, abolition of the physicians monopoly, an effective organization, better opportunities for financing and rewards, and the compulsory law of 1816.

    Full Text Available The challenges faced in delivering lifesaving vaccines to the targeted beneficiaries need to be addressed from the existing knowledge and learning from the past. This review documents the history of vaccines and vaccination in India with an objective to derive lessons for policy direction to expand the benefits of vaccination in the country. A brief historical perspective on smallpox disease and preventive efforts since antiquity is followed by an overview of 19 th century efforts to replace variolation by vaccination, setting up of a few vaccine institutes, cholera vaccine trial and the discovery of plague vaccine. The early twentieth century witnessed the challenges in expansion of smallpox vaccination, typhoid vaccine trial in Indian army personnel, and setting up of vaccine institutes in almost each of the then Indian States. In the post-independence period, the BCG vaccine laboratory and other national institutes were established; a number of private vaccine manufacturers came up, besides the continuation of smallpox eradication effort till the country became smallpox free in 1977. The Expanded Programme of Immunization (EPI (1978 and then Universal Immunization Programme (UIP (1985 were launched in India. The intervening events since UIP till India being declared non-endemic for poliomyelitis in 2012 have been described. Though the preventive efforts from diseases were practiced in India, the reluctance, opposition and a slow acceptance of vaccination have been the characteristic of vaccination history in the country. The operational challenges keep the coverage inequitable in the country. The lessons from the past events have been analysed and interpreted to guide immunization efforts.

    The development of cowpox vaccination by Jenner led to the development of immunology as a scientific discipline. The subsequent eradication of smallpox and the remarkable effects of other vaccines are among the most important contributions of biomedical science to human health. Today, the need for new vaccines has never been greater. However, in developed countries, the public's fear of vaccine-preventable diseases has waned, and awareness of potential adverse effects has increased, which is threatening vaccine acceptance. To further the control of disease by vaccination, we must develop safe and effective new vaccines to combat infectious diseases, and address the public's concerns.

    2010-10-01

    Full Text Available Despite the eradication of smallpox several decades ago, variola and monkeypox viruses still have the potential to become significant threats to public health. The current licensed live vaccinia virus-based smallpox vaccine is extremely effective as a prophylactic vaccine to prevent orthopoxvirus infections, but because of safety issues, it is no longer given as a routine vaccine to the general population. In the event of serious human orthopoxvirus infections, it is important to have treatments available for individual patients as well as their close contacts. The smallpox vaccine and vaccinia immune globulin (VIG were used in the past as therapeutics for patients exposed to smallpox. VIG was also used in patients who were at high risk of developing complications from smallpox vaccination. Thus post-exposure vaccination and VIG treatments may again become important therapeutic modalities. This paper summarizes some of the historic use of the smallpox vaccine and immunoglobulins in the post-exposure setting in humans and reviews in detail the newer animal studies that address the use of therapeutic vaccines and immunoglobulins in orthopoxvirus infections as well as the development of new therapeutic monoclonal antibodies.

  3. Frequency of adverse events after vaccination with different vaccinia strains.

    2006-08-01

    Full Text Available BACKGROUND: Large quantities of smallpox vaccine have been stockpiled to protect entire nations against a possible reintroduction of smallpox. Planning for an appropriate use of these stockpiled vaccines in response to a smallpox outbreak requires a rational assessment of the risks of vaccination-related adverse events, compared to the risk of contracting an infection. Although considerable effort has been made to understand the dynamics of smallpox transmission in modern societies, little attention has been paid to estimating the frequency of adverse events due to smallpox vaccination. Studies exploring the consequences of smallpox vaccination strategies have commonly used a frequency of approximately one death per million vaccinations, which is based on a study of vaccination with the New York City Board of Health (NYCBH strain of vaccinia virus. However, a multitude of historical studies of smallpox vaccination with other vaccinia strains suggest that there are strain-related differences in the frequency of adverse events after vaccination. Because many countries have stockpiled vaccine based on the Lister strain of vaccinia virus, a quantitative evaluation of the adverse effects of such vaccines is essential for emergency response planning. We conducted a systematic review and statistical analysis of historical data concerning vaccination against smallpox with different strains of vaccinia virus. METHODS AND FINDINGS: We analyzed historical vaccination data extracted from the literature. We extracted data on the frequency of postvaccinal encephalitis and death with respect to vaccinia strain and age of vaccinees. Using a hierarchical Bayesian approach for meta-analysis, we estimated the expected frequencies of postvaccinal encephalitis and death with respect to age at vaccination for smallpox vaccines based on the NYCBH and Lister vaccinia strains. We found large heterogeneity between findings from different studies and a time-period effect

    Full Text Available The manner in which hostilities are being conducted has changed in recent years. The battle field has transpired beyond the physical realm and now has a virtual component. Because of this, it is now easier than ever for civilians to get involved in hostilities. International Humanitarian Law applies to all situations of armed conflict and according to the principle of distinction, the parties to the conflict must, at all times, distinguish between civilians and combatants. The problem arises when the line between combatants and civilians starts to get blurry. Direct civilian participation in hostilities has been addressed in both Additional Protocols to the Geneva Conventions of 1949 and in 2009 the International Committee of the Red Cross published the Interpretive guidance on the notion of Direct Participation in Hostilities under international humanitarian law. Another document that addresses the problem of civilian direct participation is the Tallinn Manual on the International Law Applicable to Cyber Warfare prepared by an international group of experts at the invitation of the NATO Cooperative Cyber Defence Centre of Excellence in 2013. The guide prepared by the ICRC addresses the problem of civilian direct participation during conventional situations of armed conflict, while the Tallinn Manual addresses direct participation in situations of cyber warfare. The purpose of this paper is to study the application of civilian direct participation to situations of cyber warfare.

    Vaccines against infectious diseases have been available since the 1800s, when an immunization strategy against smallpox developed by Jenner gained wide acceptance. Until recently, the only vaccination strategies available involved the use of protein-based, whole killed, and attenuated live virus vaccines. These strategies have led to the development of effective vaccines against a variety of diseases with primary or prominent cutaneous manifestations. Effective and safe vaccines now used worldwide include those directed against measles and rubella (now commonly used together with a mumps vaccine as the trivalent MMR), chickenpox, and hepatitis B. The eradication of naturally occurring smallpox remains one of the greatest successes in the history of modern medicine, but stockpiles of live smallpox exist in the United States and Russia. Renewed interest in the smallpox vaccine reflects concerns about a possible bioterrorist threat using this virus. Yellow fever is a hemorrhagic virus endemic to tropical areas of South America and Africa. An effective vaccine for this virus has existed since 1937, and it is used widely in endemic areas of South America, and to a lesser extent in Africa. This vaccine is recommended once every 10 years for people who are traveling to endemic areas. Advances in immunology have led to a greater understanding of immune system function in viral diseases. Progress in genetics and molecular biology has allowed researchers to design vaccines with novel mechanisms of action (eg, DNA, vector, and VLP vaccines). Vaccines have also been designed to specifically target particular viral components, allowing for stimulation of various arms of the immune system as desired. Ongoing research shows promise in prophylactic and therapeutic vaccination for viral infections with cutaneous manifestations. Further studies are necessary before vaccines for HSV, HPV, and HIV become commercially available. PMID:12757257

    2011-09-01

    Vaccination ideally protects susceptible populations at high risk for complications of the infection. However, vaccines for these subgroups do not always provide sufficient effectiveness. The herd effect or herd immunity is an attractive way to extend vaccine benefits beyond the directly targeted population. It refers to the indirect protection of unvaccinated persons, whereby an increase in the prevalence of immunity by the vaccine prevents circulation of infectious agents in susceptible populations. The herd effect has had a major impact in the eradication of smallpox, has reduced transmission of pertussis, and protects against influenza and pneumococcal disease. A high uptake of vaccines is generally needed for success. In this paper we aim to provide an update review on the herd effect, focusing on the clinical benefit, by reviewing data for specific vaccines.

    Technological advancements, including landmark innovations in vaccinology through molecular virology, and significant transformation and changes in the society have taken place since the eradication of smallpox thirty years ago. The success with eradicating smallpox gave confidence for initiating the eradication of other diseases, such as malaria and polio. However, these efforts have not been as effective, as recorded for small pox, for a variety of reasons. There is now a debate within the global health community as to whether eradication campaigns should be abandoned in favor of less costly and perhaps more effective primary health and containment or control programmes. Significant changes that have taken place in the last thirty years, since the eradication of smallpox include, among others, (i) post-colonial political changes, with varying commitment to disease eradication initiatives, especially in the parts of the world most burdened by infectious and vaccine preventable diseases, (ii) innovations leading to the development of new and highly effective vaccines, targeted to specific diseases, (iii) the transformation brought about by improvement in education and the new global access to information (cell phones, internet, etc.), leading to an unlimited access to different types of information, subject to either positive or negative use. At the onset of eradication of smallpox, global health was confined in its operation. Today, global health is at the intersection of medical and social science disciplines-including demography, economics, epidemiology, political economy and sociology. Therefore, in considering the issue of disease eradication, medical and social perspectives must be brought into play, if future eradication programmes must succeed. The paper discusses the roles of these disciplines in disease control and eradication, especially as it affects sub Saharan Africa, the melting pot and verdant pasture of infectious diseases.

    2008-03-15

    The risk of smallpox reintroduction has motivated preparations in potential target countries. After reproducing the spatiotemporal pattern after the 1972 importation into Yugoslavia via coupled, biologically realistic systems of ordinary differential equations, we developed dynamic population models with current US age distributions and typical spatially distributed social structures. Surveillance and containment (S&C) coupled with vaccination of 95% of hospital-based health care workers (HCWs) within 2 days after the first diagnosis (estimated to be 18 days after aerosol release) were modeled after simulated exposure of 10, 50, or 10,000 people in various settings. If 90% of patients were isolated within days after symptom onset and 75% of contacts were vaccinated and monitored, S&C would reduce cases by 82%-99%. Preemptive immunization of HCWs, closing of schools, and even vaccination of as many as 80% within 1 week would have small marginal benefits. Preparations should emphasize stockpiling vaccine, training HCWs, improving laboratory capacity, and fostering an understanding of S&C. PMID:18284358

    2010-02-01

    Full Text Available Abstract Background In the event of a release of a pathogen such as smallpox, which is human-to-human transmissible and has high associated mortality, a key question is how best to deploy containment and control strategies. Given the general uncertainty surrounding this issue, mathematical modelling has played an important role in informing the likely optimal response, in particular defining the conditions under which mass-vaccination would be appropriate. In this paper, we consider two key questions currently unanswered in the literature: firstly, what is the optimal spatial scale for intervention; and secondly, how sensitive are results to the modelling assumptions made about the pattern of human contacts? Methods Here we develop a novel mathematical model for smallpox that incorporates both information on individual contact structure (which is important if the effects of contact tracing are to be captured accurately and large-scale patterns of movement across a range of spatial scales in Great Britain. Results Analysis of this model confirms previous work suggesting that a locally targeted 'ring' vaccination strategy is optimal, and that this conclusion is actually quite robust for different socio-demographic and epidemiological assumptions. Conclusions Our method allows for intuitive understanding of the reasons why national mass vaccination is typically predicted to be suboptimal. As such, we present a general framework for fast calculation of expected outcomes during the attempted control of diverse emerging infections; this is particularly important given that parameters would need to be interactively estimated and modelled in any release scenario.

Military guidelines call for relatively large volumes of prophylactic water consumption and physical activity limitations depending on the wet bulb globe temperature. However, in civilian populations, there is an increased prevalence of HI risk factors: older age, medication use, especially anticholinergic and psychotropic medications, obesity, previous HI, and skin disorders. Although dehydration is a major contributor to HI in military situations, it is unlikely in classical heat stroke among civilians. Civilian guidelines are based on the heat index. Activity levels must be restricted more for civilians, and prophylactic water consumption (beyond replacing loss from sweat) is not necessary. This review discusses the pathophysiology of heat injury, contrasts the military and civilian approach to prevention of HI, and describes appropriate field intervention for HI. PMID:9002705

  1. From foe to friend: geographical and environmental factors and the control and eradication of smallpox in India.

    Due to the highly visible nature of the disease, smallpox received a lot of attention from the colonial and independent Indian governments. An assessment of the changing official views about the impact of geographical and environmental factors on modes of variola causation and control presents insights into themes that are generally ignored in the existing historiography. Rather than being synchronised efforts, imposed top-down, provincial level officials in charge of running vaccination programmes were able to retain a great degree of autonomy and shape the nature of local immunisation drive. As a result, vaccination work in the country was often disjointed, marked by official disagreements about the usefulness of certain strategies and technological inputs, with these trends being most noticeable in rural areas. Thus, this study seeks to highlight the importance of recognising--and studying--the fractured nature of medical and public health administration in the South Asian sub-continent.

    The historical significance of smallpox eradication from Somalia lies in the fact that the country was the last to record the last endemic smallpox case in the world. Before 1977 the programme was mismanaged. In the mid-1970s, the programme was plagued with concealment. Confirmation of smallpox outbreak in Mogadishu in September 1976 delayed global smallpox eradication. The Government maintained that there was no ongoing smallpox transmission in the country after the Mogadishu outbreak and frustrated independent attempts to verify its claim. In February 1977 the Government allowed World Health Organization (WHO) epidemiologists to search, unhindered, for smallpox outside Mogadishu. Soon widespread smallpox transmission was detected. The Government appealed for international support. The strategy to stop the smallpox transmission was based on surveillance and containment. The WHO took the leading role of the campaign which, in spite of the Somalia/Ethiopia war of 1977/78, culminated in the eradication of smallpox from the country. Somalia was certified smallpox-free on 19 October 1979.

    Full Text Available A varíola acompanhou o homem por muitos séculos, causando mortes e lesões graves e irreversíveis. Usada como arma biológica em situações de guerra, volta a ser tema de discussão no mundo exatamente por essa possibilidade, apesar de ter sido erradicada das Américas em 1971, e do mundo em 1977. Os dados acumulados durante as Campanhas de Erradicação, mostram que a infecção se disseminava com relativa lentidão, através de contato muito próximo do receptor com o paciente. Infecções sub-clínicas em não-vacinados eram raras e vacinações de bloqueio em torno de novos casos, desde que estes fossem identificados e confirmados com rapidez, eram capazes de impedir a disseminação da infecção. As transmissões indiretas através de aerossóis eram menos comuns. Vacinados mesmo uma única vez, raramente apresentavam doença grave, no caso de reinfecção. A possibilidade de uso do vírus da varíola como arma biológica deve ser considerada como real, apesar de, com base nos conhecimentos atuais, serem necessárias suspensões virais de alta potência, lançadas muito próximo das pessoas a serem atingidas em grande número.Smallpox has accompanied mankind for centuries, causing deaths and permanent lesions. Used in the past as a biological weapon during wars, it has come into focus again precisely because of this renewed possibility, although the disease has been eradicated in the Americas since 1971 and worldwide since 1977. Data gathered during the eradication campaigns show that the disease spread relatively slowly through close contacts between patients and susceptibles. Sub-clinical infection in non-vaccinated individuals was a rare event, and blockade vaccination surrounding new cases (as long as these cases were confirmed early was able to prevent the disease from spreading in the community. Even with only one dose, vaccinated individuals rarely developed a serious case of the disease upon reinfection. The use of smallpox as

Although smallbox has been eliminated globally, the possibility of smallpox being used during a bioterrorist attack still exists. Large-scale smallpox vaccination is the most effective measure against smallpox bioterrorism, but may lead to serious side effects and even death. Therefore, retaining a certain proportion of immunized populations will reduce the overall losses in case of smallpox bioterrorist incidents. Based on minimized quality-adjusted life years losses, this article explored the optimal proportion of immunized populations that a country shoulol retain under the different smallpox bioterrorist attack risks.

    2011-12-30

    The 30th anniversary of the declaration of smallpox eradication is a propitious time to look back on the evolutionary history of the program, its execution, and its legacy for the future. The eradication of history's most feared disease culminated a decade-long World Health Organization campaign which began despite skepticism and doubt and succeeded despite a never ending array of obstacles occasioned by floods, civil war, famine, and bureaucratic inertia. New concepts in public health management, surveillance, and the application of large-scale programs for vaccination were fostered and matured. A new generation of young health workers emerged who applied new approaches and experienced the gratification of public health achievement. A definitive legacy for the future was the extension of the program into an "Expanded Program on Immunization", now functioning world-wide and resulting in dramatic improvements in health through control of vaccine-preventable diseases. No less important are the growing number of multi-national programs whose foundations rest on the development of active case surveillance to measure achievement and to guide progress - poliomyelitis, measles, guinea worm, and rubella.

Such preventative measures, if enacted before major military operations to retake populated areas under ISIS control begin, would better protect civilians, strengthen the government’s mission against ISIS and provide building blocks for a stable Iraq.

    Studies of the primary cultures of granulocytes, mononuclear, and monocyte-macrophage cells derived from human blood were performed using variola virus (VARV) in the doses of 0.001-0.021 PFU/cell (plaques-forming units per cell). Positive dynamics of the virus accumulation was observed only in the monocyte-macrophages with maximum values of virus concentration (5.0-5.5 Ig PFU/ml) mainly within six days after the infection. The fact of VARV replication in the monocyte-macrophages was confirmed by the data of electron microscopy. At the same time, virus vaccines when tested in doses 3.3 and 4.2 Ig PFU/ml did not show the ability to reproduce in these human cells. The people sensitivity to VARV as assessed from the data obtained on human monocyte-macrophages corresponded to -1 PFU (taking into account the smooth interaction of the virus in the body to the cells of this type), which is consistent to previously found theoretical data on the virus sensitivity. The human susceptibility to VARV assessed experimentally can be used to predict the adequacy of developed smallpox models (in vivo) based on susceptible animals. This is necessary for reliable assessment of the efficiency of development of drugs for treatment and prophylaxis of the smallpox.

    Marla B. Keenan

    2013-06-01

    Full Text Available This practice note details an emerging best practice of civilian harm mitigation in armed conflict: namely, the creation of civilian casualty tracking, analysis and response processes by a warring party or peace operation force. It asserts that in Iraq, Afghanistan and soon Somalia, these processes to better understand civilian harm and address consequences have positively shaped mission tactics, training, and overall operations. In both Iraq and Afghanistan, tracking and analysis has lead to a marked decrease in civilian casualties and facilitated the making of amends for any civilian losses. The paper argues that for warring parties to achieve their mission—particularly one with a protection of civilians mandate as with the United Nations Multidimensional Integrated Stabilization Mission in Mali (MINUSMA—they must fully understand the impact of their actions on the civilian population, positive or negative. For this reason, a Civilian Casualty Tracking, Analysis, and Response Cell should be created for MINUSMA to improve its ability mitigate risk to civilians as required by its Security Council mandate.

    Since the first demonstration of the protective effects of vaccinia inoculation, vaccination has been one of the medicine’s greatest successes. The design of vaccines against viral disease has evolved considerably over the last 50 years. Classically attenuated viruses, those created by passaging a virus in cultured cells, have proven to be an effective means for preventing many viral diseases, including smallpox, polio, measles, mumps, and yellow fever. However, empiric attenuation is not a r...

  13. Demographic impact of vaccination: a review.

    Vaccination is one of the most powerful means to save lives and to increase the level of health of mankind. However, the impact of immunization against the most threatening infectious agents on life expectancy has been the object of a still open debate. The main issues are: the relative influence of nutrition and infectious diseases on demographic patterns of populations; the possibility that lives saved thanks to vaccination are subsequently lost due to other competing causes of death; the positive indirect effect of immunization on other causes of death. With regard to past evidence, several data from the United Kingdom and Scandinavian countries show that the widespread use of smallpox vaccination starting at the beginning of the nineteenth century resulted in a marked and sustained decline not only of smallpox-related deaths, but also of the overall crude death rate, and contributed greatly to an unprecedented growth of European population. As to the present, it is estimated that 3 million children are saved annually by vaccination, but 2 million still die because they are not immunized. Tetanus, measles and pertussis are the main vaccine-preventable killers in the first years of life. Data from Bangladesh show that full implementation of EPI vaccines has the potential of reducing mortality by almost one half in children aged 1-4 years. Recent progress in the development of vaccines against agents responsible for much mortality in the developing countries make it possible to forecast a further substantial reduction of deaths for infectious diseases in the next century.

    A brief history of vaccination is presented since the Jenner's observation, through the first golden age of vaccinology (from Pasteur's era to 1938), the second golden age (from 1940 to 1970), until the current period. In the first golden age, live, such as Bacille Calmette Guérin (BCG), and yellow fever, inactivated, such as typhoid, cholera, plague, and influenza, and subunit vaccines, such as tetanus and diphtheria toxoids, have been developed. In the second golden age, the cell culture technology enabled polio, measles, mumps, and rubella vaccines be developed. In the era of modern vaccines, in addition to the conjugate polysaccharide, hepatitis A, oral typhoid, and varicella vaccines, the advent of molecular biology enabled to develop hepatitis B, acellular pertussis, papillomavirus, and rotavirus recombinant vaccines. Great successes have been achieved in the fight against infectious diseases, including the smallpox global eradication, the nearly disappearance of polio, the control of tetanus, diphtheria, measles, rubella, yellow fever, and rabies. However, much work should still be done for improving old vaccines, such as BCG, anthrax, smallpox, plague, or for developing effective vaccines against old or emerging infectious threats, such as human-immunodeficiency-virus, malaria, hepatitis C, dengue, respiratory-syncytial-virus, cytomegalovirus, multiresistant bacteria, Clostridium difficile, Ebola virus. In addition to search for innovative and effective vaccines and global infant coverage, even risk categories should adequately be protected. Despite patients under immunosuppressive therapy are globally increasing, their vaccine coverage is lower than recommended, even in developed and affluent countries. PMID:26606466

  16. Percutaneous Vaccination as an Effective Method of Delivery of MVA and MVA-Vectored Vaccines.

    Full Text Available The robustness of immune responses to an antigen could be dictated by the route of vaccine inoculation. Traditional smallpox vaccines, essentially vaccinia virus strains, that were used in the eradication of smallpox were administered by percutaneous inoculation (skin scarification. The modified vaccinia virus Ankara is licensed as a smallpox vaccine in Europe and Canada and currently undergoing clinical development in the United States. MVA is also being investigated as a vector for the delivery of heterologous genes for prophylactic or therapeutic immunization. Since MVA is replication-deficient, MVA and MVA-vectored vaccines are often inoculated through the intramuscular, intradermal or subcutaneous routes. Vaccine inoculation via the intramuscular, intradermal or subcutaneous routes requires the use of injection needles, and an estimated 10 to 20% of the population of the United States has needle phobia. Following an observation in our laboratory that a replication-deficient recombinant vaccinia virus derived from the New York City Board of Health strain elicited protective immune responses in a mouse model upon inoculation by tail scarification, we investigated whether MVA and MVA recombinants can elicit protective responses following percutaneous administration in mouse models. Our data suggest that MVA administered by percutaneous inoculation, elicited vaccinia-specific antibody responses, and protected mice from lethal vaccinia virus challenge, at levels comparable to or better than subcutaneous or intramuscular inoculation. High titers of specific neutralizing antibodies were elicited in mice inoculated with a recombinant MVA expressing the herpes simplex type 2 glycoprotein D after scarification.

    Certain theories suggest that it should be difficult or impossible to eradicate a vaccine-preventable disease under voluntary vaccination: Herd immunity implies that the individual incentive to vaccinate disappears at high coverage levels. Historically, there have been examples of declining coverage for vaccines, such as MMR vaccine and whole-cell pertussis vaccine, that are consistent with this theory. On the other hand, smallpox was globally eradicated by 1980 despite voluntary vaccination policies in many jurisdictions. Previous modeling studies of the interplay between disease dynamics and individual vaccinating behavior have assumed that infection is transmitted in a homogeneously mixing population. By comparison, here we simulate transmission of a vaccine-preventable SEIR infection through a random, static contact network. Individuals choose whether to vaccinate based on infection risks from neighbors, and based on vaccine risks. When neighborhood size is small, rational vaccinating behavior results in rapid containment of the infection through voluntary ring vaccination. As neighborhood size increases (while the average force of infection is held constant), a threshold is reached beyond which the infection can break through partially vaccinated rings, percolating through the whole population and resulting in considerable epidemic final sizes and a large number vaccinated. The former outcome represents convergence between individually and socially optimal outcomes, whereas the latter represents their divergence, as observed in most models of individual vaccinating behavior that assume homogeneous mixing. Similar effects are observed in an extended model using smallpox-specific natural history and transmissibility assumptions. This work illustrates the significant qualitative differences between behavior-infection dynamics in discrete contact-structured populations versus continuous unstructured populations.

    We analyzed the 186,102 base pairs (bp) that constitute the entire DNA genome of a highly virulent variola virus isolated from Bangladesh in 1975. The linear, double-stranded molecule has relatively small (725 bp) inverted terminal repeat (ITR) sequences containing three 69-bp direct repeat elements, a 54-bp partial repeat element, and a 105-base telomeric end-loop that can be maximally base-paired to contain 17 mismatches. Proximal to the right-end ITR sequences are another seven 69-bp elements and a 53- and a 27-bp partial element. Sequence analysis showed 187 closely spaced open reading frames specifying putative major proteins containing > or = 65 amino acids. Most of the virus proteins correspond to proteins in current databases, including 150 proteins that have > 90% identity to major gene products encoded by vaccinia virus, the smallpox vaccine. Variola virus has a group of proteins that are truncated compared with vaccinia virus counterparts and a smaller group of proteins that are elongated. The terminal regions encode several novel proteins and variants of other poxvirus proteins that potentially augment variola virus transmissibility and virulence for its only natural host, humans.

    Organization has dramatically switched to the preservation of the remaining virus after the September 2001 terrorist events in the U.S. along with the intentional release of Bacillus anthracis in the U.S. The risk of intentional release of Variola virus constitutes a minimal, yet possible risk. A smallpox epidemic could have a devastating impact due to its elevated morbidity and mortality that would inflict in non-immune human population, in addition to the ensuing panic and social unrest. Therefore, the development of national preparedness and response plans along with the availability of smallpox vaccine to be used in the post-exposure phase represent a fundamental part of the preventive efforts to cope with bioterrorism. Reestablishing a preventive vaccination program was recently recommended by the Advisory Committee on Immunization Practices (ACIP. However, the vaccine currently available has historically been associated with serious adverse reactions, even death. Thus, this recommendation has not been universally accepted. To counter an epidemic of smallpox, medical personnel in the frontline need to be prepared with updated smallpox infor mation to identify, diagnose, isolate, and treat cases if a bioterrorist attack should occur. Herein we present an in-depth review for health care personnel with relevant epidemiologic, clinical, and preventive information on smallpox.

    After Edward Jenner established human vaccination over 200 years ago, attenuated poxviruses became key players to contain the deadliest virus of its own family: Variola virus (VARV), the causative agent of smallpox. Cowpox virus (CPXV) and horsepox virus (HSPV) were extensively used to this end, passaged in cattle and humans until the appearance of vaccinia virus (VACV), which was used in the final campaigns aimed to eradicate the disease, an endeavor that was accomplished by the World Health Organization (WHO) in 1980. Ever since, naturally evolved strains used for vaccination were introduced into research laboratories where VACV and other poxviruses with improved safety profiles were generated. Recombinant DNA technology along with the DNA genome features of this virus family allowed the generation of vaccines against heterologous diseases, and the specific insertion and deletion of poxvirus genes generated an even broader spectrum of modified viruses with new properties that increase their immunogenicity and safety profile as vaccine vectors. In this review, we highlight the evolution of poxvirus vaccines, from first generation to the current status, pointing out how different vaccines have emerged and approaches that are being followed up in the development of more rational vaccines against a wide range of diseases.

    Although the development of antimicrobial drugs has advanced rapidly in the past several years, such agents act against only certain groups of microbes and are associated with increasing rates of resistance. These limitations of treatment force physicians to continue to rely on prevention, which is more effective and cost-effective than therapy. From the use of the smallpox vaccine by Jenner in the 1700s to the current concerns about biologic warfare, the technology for vaccine development has seen numerous advances. The currently available vaccines for viral illnesses include Dryvax for smallpox; the combination measles, mumps, and rubella vaccine; inactivated vaccine for hepatitis A; plasma-derived vaccine for hepatitis B; and the live attenuated Oka strain vaccine for varicella zoster. Vaccines available against bacterial illnesses include those for anthrax, Haemophilus influenzae, and Neisseria meningitidis. Currently in development for both prophylactic and therapeutic purposes are vaccines for HIV, herpes simplex virus, and human papillomavirus. Other vaccines being investigated for prevention are those for cytomegalovirus, respiratory syncytial virus, parainfluenza virus, hepatitis C, and dengue fever, among many others. Fungal and protozoan diseases are also subjects of vaccine research. Among immunoglobulins approved for prophylactic and therapeutic use are those against cytomegalovirus, hepatitis A and B, measles, rabies, and tetanus. With this progress, it is hoped that effective vaccines soon will be developed for many more infectious diseases with cutaneous manifestations. PMID:15034501

    Intradermal (ID) vaccination can offer improved immunity and simpler logistics of delivery, but its use in medicine is limited by the need for simple, reliable methods of ID delivery. ID injection by the Mantoux technique requires special training and may not reliably target skin, but is nonetheless used currently for BCG and rabies vaccination. Scarification using a bifurcated needle was extensively used for smallpox eradication, but provides variable and inefficient delivery into the skin. Recently, ID vaccination has been simplified by introduction of a simple-to-use hollow microneedle that has been approved for ID injection of influenza vaccine in Europe. Various designs of hollow microneedles have been studied preclinically and in humans. Vaccines can also be injected into skin using needle-free devices, such as jet injection, which is receiving renewed clinical attention for ID vaccination. Projectile delivery using powder and gold particles (i.e., gene gun) have also been used clinically for ID vaccination. Building off the scarification approach, a number of preclinical studies have examined solid microneedle patches for use with vaccine coated onto metal microneedles, encapsulated within dissolving microneedles or added topically to skin after microneedle pretreatment, as well as adapting tattoo guns for ID vaccination. Finally, technologies designed to increase skin permeability in combination with a vaccine patch have been studied through the use of skin abrasion, ultrasound, electroporation, chemical enhancers, and thermal ablation. The prospects for bringing ID vaccination into more widespread clinical practice are encouraging, given the large number of technologies for ID delivery under development. PMID:21472533

  9. Vaccination and Clinical Severity: Is the Effectiveness of Contact Tracing and Case Isolation Hampered by Past Vaccination?

    Directory of Open Access Journals (Sweden)

    Hiroshi Nishiura

    2013-02-01

    Full Text Available While contact tracing and case isolation are considered as the first choice of interventions against a smallpox bioterrorist event, their effectiveness under vaccination is questioned, because not only susceptibility of host and infectiousness of case but also the risk of severe clinical manifestations among cases is known to be reduced by vaccine-induced immunity, thereby potentially delaying the diagnosis and increasing mobility among vaccinated cases. We employed a multi-type stochastic epidemic model, aiming to assess the feasibility of contact tracing and case isolation in a partially vaccinated population and identify data gaps. We computed four epidemiological outcome measures, i.e., (i the threshold of a major epidemic under the interventions; (ii the expected total number of cases; (iii the probability of extinction, and (iv the expected duration of an outbreak, demonstrating that all of these outcomes critically depend on the clinical impact of past vaccination on the diagnosis and movement of vaccinated cases. We discuss that, even in the absence of smallpox in the present day, one should consider the way to empirically quantify the delay in case detection and an increase in the frequency of contacts among previously vaccinated cases compared to unvaccinated during the early stage of an epidemic so that the feasibility of contact tracing and case isolation in a vaccinated population can be explicitly assessed.

  10. Discriminating military and civilian traumatic brain injuries.

    Science.gov (United States)

    Reid, Matthew W; Velez, Carmen S

    2015-05-01

    Traumatic brain injury (TBI) occurs at higher rates among service members than civilians. Explosions from improvised explosive devices and mines are the leading cause of TBI in the military. As such, TBI is frequently accompanied by other injuries, which makes its diagnosis and treatment difficult. In addition to postconcussion symptoms, those who sustain a TBI commonly report chronic pain and posttraumatic stress symptoms. This combination of symptoms is so typical they have been referred to as the "polytrauma clinical triad" among injured service members. We explore whether these symptoms discriminate civilian occurrences of TBI from those of service members, as well as the possibility that repeated blast exposure contributes to the development of chronic traumatic encephalopathy (CTE). This article is part of a Special Issue entitled 'Traumatic Brain Injury'.

    Full Text Available Whilst the protection of civilians (POC in conflict has been a recurring feature of the humanitarian discourse the same has not been true in military doctrines, where the protection of civilians has long been cast in terms of arms bearers upholding their responsibilities under international humanitarian law (IHL. However, opportunities for and pressures on military actors to develop more specific capacities and approaches in this field have grown: partly as a response to the changing nature, location and scope of conflict, particularly the increasing proportion of internal conflicts fought by irregular armed groups in urban environments. It is also a response to the scale and complexity of protection challenges in the Balkans, Rwanda, Darfur and Libya - each of which has clearly demonstrated that threats to civilians are complex and dynamic and that no single international actor is capable of mitigating them without significant support from other institutions (O’Callaghan and Pantuliano, 2007. Despite the enormous growth in opportunities for interaction between militaries and humanitarians there is only a very limited literature on their interaction over protection issues and evaluations of the emerging doctrines. Consequently this article charts the growth in military policies towards POC in the UN, UK, NATO and a range of other states as well as drawing attention to the challenges that still remain in operationalising responses.

    Vaccinating pregnant women in order to protect them, the fetus, and the child has become universal in no way at all. Prejudice in health professionals add to fears of women and their families. Both these feelings are not supported by even the smallest scientific data. Harmlessness for the mother and the child has been observed for seasonal, pandemic, or quadrivalent influenza, mono, combined polysaccharide or conjugated meningococcal or pneumococcal, tetanus toxoid, acellular pertussis, human papillomavirus, cholera, hepatitis A, Japanese encephalitis, rabies, anthrax, smallpox, yellow fever, mumps, measles and rubella combined, typhoid fever, inactivated or attenuated polio vaccines, and Bacillus Calmétte Guerin vaccines. Instead, the beneficial effects of influenza vaccine for the mother and the child as well as of pertussis vaccine for the child have been demonstrated. Obstetrician-gynecologists, general practitioners, and midwives must incorporate vaccination into their standard clinical care. Strong communication strategies effective at reducing parental vaccine hesitancy and approval of regulatory agencies for use of vaccines during pregnancy are needed. It must be clear that the lack of pre-licensure studies in pregnant women and, consequently, the lack of a statement about the use of the vaccine in pregnant women does not preclude its use in pregnancy.

    2009-11-01

    Vaccines are considered to be among the greatest medical discoveries, credited with the virtual eradication of some diseases and the consequent improved survival and quality of life of the at-risk population. With that, vaccines are among the environmental factors implicated as triggers for the development of inflammatory myopathies. The sporadic reports on vaccine-induced inflammatory myopathies include cases of hepatitis B virus, bacillus Calmette-Guérin, tetanus, influenza, smallpox, polio, diphtheria, diphtheria-pertussis-tetanus, combination of diphtheria with scarlet fever and diphtheria-pertussis-tetanus with polio vaccines. However, a significant increase in the incidence of dermatomyositis or polymyositis after any massive vaccination campaign has not been reported in the literature. In study patients with inflammatory myopathies, no recent immunization was recorded in any of the patients. Moreover, after the 1976 mass flu vaccination, no increase in the incidence of inflammatory myopathies was observed. Although rare, macrophagic myofasciitis has been reported following vaccination and is attributed to the aluminium hydroxide used as an adjuvant in some vaccines. Prospective multicenter studies are needed to identify potential environmental factors, including vaccines, as potential triggers for inflammatory myopathies.

  4. The Development of an AIDS Mucosal Vaccine

    Full Text Available It is well known that mucosal tissues contain the largest surface area of the human body and are the front line of natural host defense against various pathogens. In fact, more than 80% of infectious disease pathogens probably gain entry into the susceptible human hosts through open mucosal surfaces. Human immunodeficiency virus type one (HIV-1, a mainly sexually transmitted virus, also primarily targets the vaginal and gastrointestinal mucosa as entry sites for viral transmission, seeding, replication and amplification. Since HIV-1 establishes its early replication in vaginal or rectal mucosal tissues, the induction of sufficient mucosal immunity at the initial site of HIV-1 transmission becomes essential for a protective vaccine. However, despite the fact that current conventional vaccine strategies have remained unsuccessful in preventing HIV-1 infection, sufficient financial support and resources have yet to be given to develop a vaccine able to elicit protective mucosal immunity against sexual transmissions. Interestingly, Chinese ancestors invented variolation through intranasal administration about one thousand years ago, which led to the discovery of a successful smallpox vaccine and the final eradication of the disease. It is the hope for all mankind that the development of a mucosal AIDS vaccine will ultimately help control the AIDS pandemic. In order to discover an effective mucosal AIDS vaccine, it is necessary to have a deep understanding of mucosal immunology and to test various mucosal vaccination strategies.

  5. Civilian Aeronautical Futures - The Responsibly Imaginable

    2006-01-01

    Since 1940 Aeronautics has had an immense impact upon Global Human lifestyles and affairs - in both the Civilian and Military arenas. During this period Long distance Train and Ship passenger transport were largely supplanted by Air Travel and Aviation assumed a dominant role in warfare. The early 1940 s to the mid 1970 s was a particularly productive period in terms of Aeronautical Technology. What is interesting is that, since the mid 1970 s, the rate of Aeronautical Technological Progress has been far slower, the basic technology in nearly all of our current Aero Systems dates from the mid 70 s or earlier. This is especially true in terms of Configuration Aerodynamics, Aeronautics appears to have "settled" on the 707, double delta and rotary wing as the approach of choice for Subsonic long haul, supersonic cruise and VTOL respectively. Obviously there have been variants and some niche digression from this/these but in the main Aeronautics, particularly civilian Aeronautics, has become a self-professed "mature", Increasingly "Commodity", Industry. The Industry is far along an existing/deployed technology curve and focused, now for decades, on incremental/evolutionary change - largely Appliers vs. developers of technology. This is, of course, in sharp contrast to the situation in the early-to-later 20th century where Aeronautics was viewed as A Major Technological Engine, much the way IT/Bio/Nano/Energetics/Quantum Technologies are viewed today. A search for Visionary Aeronautical "Futures" papers/projections indicates a decided dearth thereof over the last 20 plus years compared to the previous quarter Century. Aeronautics is part of Aerospace and Aerospace [including Aeronautics] has seen major cutbacks over the last decades. Some numbers for the U.S. Aerospace Industry serve as examples.

  7. Behavioral and health implications of civilian spaceflight.

    Wichman, Harvey A

    2005-06-01

    The current enthusiasm over the prospect of space tourism and the belief among many that such civilian spaceflight is imminent are characterized herein. There are many concerns about screening and certifying passengers for future spaceflight. Efforts by several organizations to propose such screening are cited. The problem with some of these proposals, which treat all types of spaceflight the same, is that they are so restrictive that too few people would be eligible for space travel to have a viable tourism industry. However, not all types of spaceflight are the same, so the distinctions between them need to be clarified. Of the five types of spaceflight described, one is proposed as the most likely to be the first significant phase of space tourism: long-term microgravity flight in low Earth orbit. But because of human problems with long-term exposure to microgravity, this phase requires rather conservative screening and extensive training. However, prior to discussing the passenger issues related to this early phase of space tourism, the reasons why Earth-like gravity, as well as microgravity, must be made available to spacefarers before space tourism can take place on a grand scale need to be explained. Finally, major passenger medical and behavioral issues of the first phase of orbital space tourism-long-term microgravity flight-are discussed. PMID:15943209

  8. Sewers and scapegoats: spatial metaphors of smallpox in nineteenth century San Francisco.

    Science.gov (United States)

    Craddock, S

    1995-10-01

    Medical geography is slowly including more social and cultural theory in its analysis of health issues. Yet there is still room for theoretical growth in the discipline, in areas such as historical inquiry, metaphoric landscapes of disease, and the role of disease and its interpretations in the production of place. With the example of four smallpox epidemics in nineteenth century San Francisco, application of these concepts is illustrated. Each successive epidemic in San Francisco brought stronger association of the disease with Chinatown, until an almost complete metonymy of place and disease had occurred by the last decades of the century. The articulation of biased medical theory onto a landscape of xenophobia engendered this metaphorical transformation of Chinatown into a pustule of contagion threatening to infect the rest of the urban body. A less metaphoric mapping of smallpox focused on the sewer. According to 19th-century miasmatic theories of epidemiology, sewers were the most dangerous urban topographical feature. In an increasingly class-stratified city, they undercut attempts of the upper classes to escape disease by carrying smallpox-causing miasmas across class and ethnic boundaries. A reinvigorated sanitation movement was the result. Both reactions to smallpox epidemics had significant influence in shaping San Francisco's landscape, real and symbolic. PMID:8545670

    2015-01-01

    Multiple cornerstones have shaped the history of vaccines, which may contain live-attenuated viruses, inactivated organisms/viruses, inactivated toxins, or merely segments of the pathogen that could elicit an immune response. The story began with Hippocrates 400 B.C. with his description of mumps and diphtheria. No further discoveries were recorded until 1100 A.D. when the smallpox vaccine was described. During the eighteenth century, vaccines for cholera and yellow fever were reported and Edward Jenner, the father of vaccination and immunology, published his work on smallpox. The nineteenth century was a major landmark, with the "Germ Theory of disease" of Louis Pasteur, the discovery of the germ tubercle bacillus for tuberculosis by Robert Koch, and the isolation of pneumococcus organism by George Miller Sternberg. Another landmark was the discovery of diphtheria toxin by Emile Roux and its serological treatment by Emil Von Behring and Paul Ehrlih. In addition, Pasteur was able to generate the first live-attenuated viral vaccine against rabies. Typhoid vaccines were then developed, followed by the plague vaccine of Yersin. At the beginning of World War I, the tetanus toxoid was introduced, followed in 1915 by the pertussis vaccine. In 1974, The Expanded Program of Immunization was established within the WHO for bacille Calmette-Guerin, Polio, DTP, measles, yellow fever, and hepatitis B. The year 1996 witnessed the launching of the International AIDS Vaccine Initiative. In 1988, the WHO passed a resolution to eradicate polio by the year 2000 and in 2006; the first vaccine to prevent cervical cancer was developed. In 2010, "The Decade of vaccines" was launched, and on April 1st 2012, the United Nations launched the "shot@Life" campaign. In brief, the armamentarium of vaccines continues to grow with more emphasis on safety, availability, and accessibility. This mini review highlights the major historical events and pioneers in the course of development of vaccines

    The stockpiling of live vaccinia virus vaccines has enhanced biopreparedness against the intentional or accidental release of smallpox. Ongoing research on future generation smallpox vaccines is providing key insights into protective immune responses as well as important information about subunit vaccine design strategies. For protein-based recombinant subunit vaccines, the formulation and stability of candidate antigens with different adjuvants are important factors to consider for vaccine design. In this work, a non-tagged secreted L1-protein, a target antigen on mature virus, was expressed using recombinant baculovirus technology and purified. To identify optimal formulation conditions for L1, a series of biophysical studies was performed over a range of pH and temperature conditions. The overall physical stability profile was summarized in an empirical phase diagram. Another critical question to address for development of an adjuvanted-vaccine was if immunogenicity and protection could be affected by the interactions and binding of L1 to aluminum salts (Alhydrogel) with and without a second adjuvant, CpG. We thus designed a series of vaccine formulations with different binding interactions between the L1 and the two adjuvants, and then performed a series of vaccination-challenge experiments in mice including measurement of antibody responses and post-challenge weight-loss and survival. We found that better humoral responses and protection were conferred with vaccine formulations when the L1-protein was adsorbed to Alhydrogel. These data demonstrate that designing vaccine formulation conditions to maximize antigen-adjuvant interactions is a key factor in smallpox subunit vaccine immunogenicity and protection.

  19. Nudging Armed Groups: How Civilians Transmit Norms of Protection

    Directory of Open Access Journals (Sweden)

    Oliver Kaplan

    2013-12-01

    Full Text Available What are the varying roles that norms play to either enable or constrain violence in armed conflict settings? The article examines this question by drawing on experiences from communities and armed groups in Colombia and Syria. It begins by presenting an explanation of how norms of violence and nonviolence may arise within communities and influence the behavior of civilian residents, reducing the chances of them becoming involved with armed groups. It then considers how civilian communities can transmit those same norms, shared understandings, and patterns of interaction to the ranks of illegal armed groups and subsequently shape their decisions about the use of violence against civilians. The author argues that civilians may be better positioned to promote the principles codified in International Humanitarian Law than international humanitarian organizations because they have closer contact with irregular armed actors and are viewed with greater legitimacy. The analysis illustrates that to better understand civilian protection mechanisms it is essential to study the interactions between communities and armed actors.

    My dissertation untangles the oxymoron of Romantic medicine. The literary history of inoculation, I contend, reveals that smallpox eradication was as much a triumph of the literary imagination as it was an achievement of Enlightenment science. Underlying this argument is the larger disciplinary question: Who counts as a producer of scientific knowledge? My project uncovers a surprisingly literary history of medicine that includes poetry and imaginative fiction in the discovery, propagation, a...

    Full Text Available Due to the wars in Iraq and Afghanistan, the unmet medical and psychological needs of military personnel are creating major challenges. Increasingly, active duty military personnel are seeking physical and mental health services from civilian professionals. The Civilian Medical Resources Network attempts to address these unmet needs. Participants in the Network include primary care and mental health practitioners in all regions of the country. Network professionals provide independent assessments, clinical interventions in acute situations, and documentation that assists GIs in obtaining reassignment or discharge. Most clients who use Network services come from low-income backgrounds and manifest psychological rather than physical disorders. Qualitative themes in professional-client encounters have focused on ethical conflicts, the impact of violence without meaning (especially violence against civilians, and perceived problems in military health and mental health policies. Unmet needs of active duty military personnel deserve more concerted attention from medical professionals and policy makers.

    Full Text Available Abstract Leptospirosis is a serious infection disease caused by pathogenic strains of the Leptospira spirochetes, which affects not only humans but also animals. It has long been expected to find an effective vaccine to prevent leptospirosis through immunization of high risk humans or animals. Although some leptospirosis vaccines have been obtained, the vaccination is relatively unsuccessful in clinical application despite decades of research and millions of dollars spent. In this review, the recent advancements of recombinant outer membrane protein (OMP vaccines, lipopolysaccharide (LPS vaccines, inactivated vaccines, attenuated vaccines and DNA vaccines against leptospirosis are reviewed. A comparison of these vaccines may lead to development of new potential methods to combat leptospirosis and facilitate the leptospirosis vaccine research. Moreover, a vaccine ontology database was built for the scientists working on the leptospirosis vaccines as a starting tool.

    Vaccine refusal received a lot of press with the 2015 Disneyland measles outbreak, but vaccine refusal is only a fraction of a much larger problem of vaccine delay and hesitancy. Opposition to vaccination dates back to the 1800 s, Edward Jenner, and the first vaccine ever. It has never gone away despite the public's growing scientific sophistication. A variety of factors contribute to modern vaccine hesitancy, including the layperson's heuristic thinking when it comes to balancing risks and benefits as well as a number of other features of vaccination, including falling victim to its own success. Vaccine hesitancy is pervasive, affecting a quarter to a third of US parents. Clinicians report that they routinely receive requests to delay vaccines and that they routinely acquiesce. Vaccine rates vary by state and locale and by specific vaccine, and vaccine hesitancy results in personal risk and in the failure to achieve or sustain herd immunity to protect others who have contraindications to the vaccine or fail to generate immunity to the vaccine. Clinicians should adopt a variety of practices to combat vaccine hesitancy, including a variety of population health management approaches that go beyond the usual call to educate patients, clinicians, and the public. Strategies include using every visit to vaccinate, the creation of standing orders or nursing protocols to provide vaccination without clinical encounters, and adopting the practice of stating clear recommendations. Up-to-date, trusted resources exist to support clinicians' efforts in adopting these approaches to reduce vaccine hesitancy and its impact.

  9. Resister's logic: the anti-vaccination arguments of Alfred Russel Wallace and their role in the debates over compulsory vaccination in England, 1870-1907.

    Science.gov (United States)

    Fichman, Martin; Keelan, Jennifer E

    2007-09-01

    In the 1880s, Alfred Russel Wallace, the celebrated co-discoverer of natural selection, launched himself into the centre of a politicised and polarised debate over the unpopular compulsory vaccination laws in England. Wallace never wavered in his belief that smallpox vaccination was useless and likely dangerous. Six years before his death, the anti-vaccinationists successfully secured a conscience clause that effectively dismantled the compulsory vaccination laws. Several other important Victorian scientists joined Wallace in the fight to repeal compulsory vaccination arguing that widely held views on the effectiveness of vaccination and evidence for immunity were inconclusive in the light of (then) contemporary standards of evidence. This article situates Wallace's anti-vaccination logic within the broader matrix of sociopolitical and cultural reform movements of the late Victorian era. Additionally it provides the first detailed analysis of his critique of vaccination science, in particular the role statistics played in his arguments. In this period, both pro-vaccinationists and anti-vaccinationists invested great efforts in collating and analysing statistical data sets that either supported or refuted the claims of vaccination's effectiveness. While each side presented 'controlled' case studies to support their assertions, without an unambiguous test to measure or demonstrate vaccination's effectiveness, the anti-vaccinationists continued to mount credible statistical critiques of vaccination science.

    Vaccination is one of the most effective interventions in global health. The worldwide vaccination programs significantly reduced the number of deaths caused by infectious agents. A successful example was the eradication of smallpox in 1979 after two centuries of vaccination campaigns. Since the first variolation administrations until today, the knowledge on immunology has increased substantially. This knowledge combined with the introduction of cell culture and DNA recombinant technologies revolutionized vaccine design. This review will focus on vaccines against human viral pathogens, recent developments on vaccine design and cell substrates used for their manufacture. While the production of attenuated and inactivated vaccines requires the use of the respective permissible cell substrates, the production of recombinant antigens, virus-like particles, vectored vaccines and chimeric vaccines requires the use - and often the development - of specific cell lines. Indeed, the development of novel modern viral vaccine designs combined with, the stringent safety requirements for manufacture, and the better understanding on animal cell metabolism and physiology are increasing the awareness on the importance of cell line development and engineering areas. A new era of modern vaccinology is arriving, offering an extensive toolbox to materialize novel and creative ideas in vaccine design and its manufacture.

    This article utilizes the Foucauldian concepts of biopower and normalization to give an analysis of the debate surrounding the controversial administration of the HPV vaccine to adolescents. My intention is not to solve the problem, rather to utilize a Foucauldian framework to bring various facets of the issue to light, specifically the way the vaccine contributes to strategies of power in reference to how young adults develop within relationships of power. To begin, the article provides an overview of the Foucauldian concepts of biopower and normalization, including how these two strategies of power were present in the administration of the smallpox vaccine in the 19th century. Next, information about HPV and the history of the current controversy in the United States is presented. Lastly, the article presents an analysis of the strategies of biopower and normalization present in the debate on HPV, including an emphasis on how the vaccination is similar to, and different from, 19th century smallpox vaccination. It also explores the way that mechanisms of disease control affect and are affected by individual subjects, in this case, adolescents. PMID:26438668

    Plasmid DNA,an effective vaccine vector,can induce both cellular and humoral immune responses.However,plasmid DNA raises issues concerning potential genomic integration after injection.This issue should be considered in preclinical studies.Tiantan vaccinia virus (TV) has been most widely utilized in eradicating smallpox in China.This virus has also been considered as a successful vaccine vector against a few infectious diseases.Potent T cell responses through T-cell receptor (TCR) could be induced by three injections of the DNA prime vaccine followed by a single injection of recombinant vaccinia vaccine.To develop a safer immunization strategy,a single DNA prime followed by a single recombinant Tiantan vaccinia (rTV) AIDS vaccine was used to immunize mice.Our data demonstrated that one DNA prime/rTV boost regimen induced mature TCR activation with high functional avidity,preferential T cell Vβ receptor usage and high sensitivity to anti-CD3 antibody stimulation.No differences in T cell responses were observed among one,two or three DNA prime/rTV boost regimens.This study shows that one DNA prime/rTV boost regimen is sufficient to induce potent T cell responses against HIV.

    It is many years since the general population has been vaccinated against smallpox virus. Here, we report that human leukocyte antigen (HLA) class I restricted T cell epitopes can be recognized more than 30 years after vaccination. Using bioinformatic methods, we predicted 177 potential cytotoxic T...... lymphocyte epitopes. Eight epitopes were confirmed to stimulate IFN-gamma release by T cells in smallpox-vaccinated subjects. The epitopes were restricted by five supertypes (HLA-A1, -A2, -A24 -A26 and -B44). Significant T cell responses were detected against 8 of 45 peptides with an HLA class I affinity...... of K(D) less than or equal to 5 nM, whereas no T cell responses were detected against 60 peptides with an HLA affinity of K(D) more than 5 nM. All epitopes were fully conserved in seven variola, vaccinia and cowpox strains. Knowledge of the long-term response to smallpox vaccination may lead...

    Full Text Available Abstract Background Because smallpox (variola major may be used as a biological weapon, we reviewed outbreaks in post-World War II Europe and North America in order to understand smallpox transmission patterns. Methods A systematic review was used to identify papers from the National Library of Medicine, Embase, Biosis, Cochrane Library, Defense Technical Information Center, WorldCat, and reference lists of included publications. Two authors reviewed selected papers for smallpox outbreaks. Results 51 relevant outbreaks were identified from 1,389 publications. The median for the effective first generation reproduction rate (initial R was 2 (range 0–38. The majority outbreaks were small (less than 5 cases and contained within one generation. Outbreaks with few hospitalized patients had low initial R values (median of 1 and were prolonged if not initially recognized (median of 3 generations; outbreaks with mostly hospitalized patients had higher initial R values (median 12 and were shorter (median of 3 generations. Index cases with an atypical presentation of smallpox were less likely to have been diagnosed with smallpox; outbreaks in which the index case was not correctly diagnosed were larger (median of 27.5 cases and longer (median of 3 generations compared to outbreaks in which the index case was correctly diagnosed (median of 3 cases and 1 generation. Conclusion Patterns of spread during Smallpox outbreaks varied with circumstances, but early detection and implementation of control measures is a most important influence on the magnitude of outbreaks. The majority of outbreaks studied in Europe and North America were controlled within a few generations if detected early.

    Full Text Available BACKGROUND: Warring groups that compete to dominate a civilian population confront contending behavioral options: target civilians or battle the enemy. We aimed to describe degrees to which combatant groups concentrated lethal behavior into intentionally targeting civilians as opposed to engaging in battle with opponents in contemporary armed conflict. METHODOLOGY/PRINCIPAL FINDINGS: We identified all 226 formally organized state and non-state groups (i.e. actors that engaged in lethal armed conflict during 2002-2007: 43 state and 183 non-state. We summed civilians killed by an actor's intentional targeting with civilians and combatants killed in battles in which the actor was involved for total fatalities associated with each actor, indicating overall scale of armed conflict. We used a Civilian Targeting Index (CTI, defined as the proportion of total fatalities caused by intentional targeting of civilians, to measure the concentration of lethal behavior into civilian targeting. We report actor-specific findings and four significant trends: 1. 61% of all 226 actors (95% CI 55% to 67% refrained from targeting civilians. 2. Logistic regression showed actors were more likely to have targeted civilians if conflict duration was three or more years rather than one year. 3. In the 88 actors that targeted civilians, multiple regressions showed an inverse correlation between CTI values and the total number of fatalities. Conflict duration of three or more years was associated with lower CTI values than conflict duration of one year. 4. When conflict scale and duration were accounted for, state and non-state actors did not differ. We describe civilian targeting by actors in prolonged conflict. We discuss comparable patterns found in nature and interdisciplinary research. CONCLUSIONS/SIGNIFICANCE: Most warring groups in 2002-2007 did not target civilians. Warring groups that targeted civilians in small-scale, brief conflict concentrated more lethal

    The objective of this project, which was supported by the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) Chemical and Biological Division (CBD), was to investigate options for the decontamination of the exteriors and interiors of vehicles in the civilian setting in order to restore those vehicles to normal use following the release of a highly toxic chemical. The decontamination of vehicles is especially challenging because they often contain sensitive electronic equipment, multiple materials some of which strongly adsorb chemical agents, and in the case of aircraft, have very rigid material compatibility requirements (i.e., they cannot be exposed to reagents that may cause even minor corrosion). A systems analysis approach was taken examine existing and future civilian vehicle decontamination capabilities.

    This study aimed to investigate potential psychological distress among members of the civilian police force, based on gender differences. It analyzes data from previous research on work, health conditions, and quality of life in the civilian police using both quantitative and qualitative methods. The study included and tested data from the questionnaire applied to a statistically representative sample of 2,746 civilian police (80.8% males and 19.2% females) from the city of Rio de Janeiro, Brazil, according to gender variables and position in the police force (administrative, technical, and operational law enforcement). The study presents an overview of social and economic characteristics, job conditions, health problems, and quality of life, highlighting the areas of information where gender appears as an important factor. The Self-Reported Questionnaire (SRQ-20) was used to investigate psychological distress comparing males and females. The results did not show gender differences in psychological distress, but did identify significant differences in some items in the scale. Female police, especially in technical positions, showed a higher proportion than males. The conclusions corroborate some previous research. PMID:17187109

    OBJECTIVE To evaluate the audiometric profile of civilian pilots according to the noise exposure level. METHODS This observational cross-sectional study evaluated 3,130 male civilian pilots aged between 17 and 59 years. These pilots were subjected to audiometric examinations for obtaining or revalidating the functional capacity certificate in 2011. The degree of hearing loss was classified as normal, suspected noise-induced hearing loss, and no suspected hearing loss with other associated complications. Pure-tone air-conduction audiometry was performed using supra-aural headphones and acoustic stimulus of the pure-tone type, containing tone thresholds of frequencies between 250 Hz and 6,000 Hz. The independent variables were professional categories, length of service, hours of flight, and right or left ear. The dependent variable was pilots with suspected noise-induced hearing loss. The noise exposure level was considered low/medium or high, and the latter involved periods > 5,000 flight hours and > 10 years of flight service. RESULTS A total of 29.3% pilots had suspected noise-induced hearing loss, which was bilateral in 12.8% and predominant in the left ear (23.7%). The number of pilots with suspected hearing loss increased as the noise exposure level increased. CONCLUSIONS Hearing loss in civilian pilots may be associated with noise exposure during the period of service and hours of flight. PMID:25372170

    Full Text Available Deployed to Mogadishu in March 2007, it was not until late May 2013 that the African Union Mission in Somalia (AMISOM adopted a mission-wide protection-of-civilians (PoC strategy. This article helps explain this long delay by highlighting the multiple PoC challenges faced by the mission. First, it shows how AMISOM’s relevant documents contained a variety of mixed messages on PoC issues. Second, it illustrates some of the ways in which the African Union was hardly an ideal actor to implement a civilian protection agenda because of its limited previous experience with these issues. Third, it analyzes the ways in which AMISOM was itself sometimes a source of civilian harm in Mogadishu. The fourth section examines the remedial policies AMISOM adopted to try and alleviate this problem. The conclusion reflects on the current PoC challenges facing AMISOM and suggests that to be successful the new mission-wide strategy must overcome these material, legal, moral, and doctrinal challenges.

    In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N = 2017) of those who died and 93.8% (N = 6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002-2005 to security forces or general public in 2006-2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P ≤ 0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.

    Uncontrolled hemorrhage and exsanguination are the leading cause of preventable death, and resuscitative therapy is a critical component for survival. In various combinations, fresh whole blood, blood components, colloids, and crystalloids have all been staples of trauma care. The use of fresh whole blood is a well-established military practice that has saved the lives of thousands of American and coalition military personnel. Civilian use of fresh whole blood is far less established owing to the wide availability of individual blood components. However, this highly tailored blood supply is vulnerable to both natural and man-made disasters. In the event of such disruption, such as a major hurricane, it may be necessary for civilian hospitals to rapidly enact a fresh whole blood program. Therefore, the aim of this article is to review the current use of blood therapy for trauma resuscitation, the US military's approach to fresh whole blood, and how maintaining a civilian capacity for fresh whole blood collection in the event of future man-made and natural disasters is key to promoting survival from trauma.

CD4(+ T cell responses are an important component of immunity induced by current vaccinia-based vaccines, and likely will be required for new subunit vaccine approaches, but to date vaccinia-specific CD4(+ T cell responses have been poorly characterized, and CD4(+ T cell epitopes have been reported only recently. Classical approaches used to identify T cell epitopes are not practical for large genomes like vaccinia. We developed and validated a highly efficient computational approach that combines prediction of class II MHC-peptide binding activity with prediction of antigen processing and presentation. Using this approach and screening only 36 peptides, we identified 25 epitopes recognized by T cells from vaccinia-immune individuals. Although the predictions were made for HLA-DR1, eight of the peptides were recognized by donors of multiple haplotypes. T cell responses were observed in samples of peripheral blood obtained many years after primary vaccination, and were amplified after booster immunization. Peptides recognized by multiple donors are highly conserved across the poxvirus family, including variola, the causative agent of smallpox, and may be useful in development of a new generation of smallpox vaccines and in the analysis of the immune response elicited to vaccinia virus. Moreover, the epitope identification approach developed here should find application to other large-genome pathogens.

    Full Text Available Serologic data on diseases that are preventable by vaccines are necessary to evaluate the success of immunization programs and to identify susceptible subgroups. In the present study, we determined serum IgG levels against diphtheria toxin of military and civilian blood donors (N = 75; 69.3% males and 30.7% females aged 18-64 years, from the Brazilian Army Biology Institute, Rio de Janeiro, using a commercial diphtheria kit (Diphtheria IgG ELISA; IBL, Germany. Most (63% unprotected military donors were from the older age group of 41 to 64 years. In contrast, the majority (71% of young military donors (18 to 30 years were fully protected. About half of the military donors aged 31 to 40 years were protected against diphtheria. Among the civilians, about 50% of persons aged 18 to 30 years and 31 to 40 years had protective antibody levels against diphtheria as also did 64% of individuals aged 41 to 64 years. All civilians had a similar antibody response (geometric mean = 0.55 IU/mL independent of age group. Military donors aged 18-30 years had higher IgG levels (geometric mean = 0.82 IU/mL than military donors of 41-64 years (geometric mean = 0.51 IU/mL; P > 0.05. In conclusion, the existence of a considerable proportion of susceptible adults supports the position that reliable data on the immune status of the population should be maintained routinely and emphasizes the importance of adequate immunization during adulthood.

  8. Another vaccine, another story: BCG vaccination against tuberculosis in India, 1948 to 1960 Outra vacina, outra história: a vacinação de BCG contra tuberculose na Índia, 1948 a 1960

    Full Text Available Through an examination of mass BCG vaccination against tuberculosis in India between 1948 and 1960 this article draws attention to the diversity of the history of vaccination. The features of vaccination campaigns often differed from those of the celebrated campaign to eradicate smallpox. Due to differences between smallpox and tuberculosis as well as between the vaccines developed against them, an analysis of BCG mass vaccination against tuberculosis seems particularly well suited for this purpose. Three points of difference are identified. First, in non-Western contexts BCG vaccination procedures were modified to a greater extent than vaccination against smallpox. Second, tuberculosis lacked the drama and urgency of smallpox and BCG vaccination campaigns suffered more from recruitment problems than did the more "heroic" smallpox eradication campaign. Third, the BCG vaccine was contested in medical circles and was much better suited than the vaccine against smallpox as a vehicle for the articulation of concerns about post-colonial modernization.Através da observação da vacinação em massa de BCG contra a tuberculose na Índia durante os anos de 1948 a 1960, este artigo chama a atenção para a diversidade da história da vacinação. As características das campanhas de vacinação geralmente diferem daquelas celebradas nas campanhas para erradicação da varíola. Devido às diferenças entre a varíola e a turberculose, assim como entre as vacinas desenvolvidas para combater essas doenças, uma análise da vacinação em massa de BCG contra a turberculose parece especialmente bem situada para essa proposta. Três pontos de diferença foram identificados. O primeiro é que em contextos não ocidentais os procedimentos da vacinação de BCG foram modificados em uma extensão maior do que a vacinação contra a varíola. Em segundo lugar, a tuberculose não tinha o drama e a urgência da varíola, e as campanhas de vacinação de BCG

  10. Susceptibility of Marmosets (Callithrix jacchus to Monkeypox Virus: A Low Dose Prospective Model for Monkeypox and Smallpox Disease.

    Directory of Open Access Journals (Sweden)

    Eric M Mucker

    Full Text Available Although current nonhuman primate models of monkeypox and smallpox diseases provide some insight into disease pathogenesis, they require a high titer inoculum, use an unnatural route of infection, and/or do not accurately represent the entire disease course. This is a concern when developing smallpox and/or monkeypox countermeasures or trying to understand host pathogen relationships. In our studies, we altered half of the test system by using a New World nonhuman primate host, the common marmoset. Based on dose finding studies, we found that marmosets are susceptible to monkeypox virus infection, produce a high viremia, and have pathological features consistent with smallpox and monkeypox in humans. The low dose (48 plaque forming units required to elicit a uniformly lethal disease and the extended incubation (preclinical signs are unique features among nonhuman primate models utilizing monkeypox virus. The uniform lethality, hemorrhagic rash, high viremia, decrease in platelets, pathology, and abbreviated acute phase are reflective of early-type hemorrhagic smallpox.

  13. Chasing Jenner's vaccine: revisiting cowpox virus classification.

    Directory of Open Access Journals (Sweden)

    Darin S Carroll

    Full Text Available Cowpox virus (CPXV is described as the source of the first vaccine used to prevent the onset and spread of an infectious disease. It is one of the earliest described members of the genus Orthopoxvirus, which includes the viruses that cause smallpox and monkeypox in humans. Both the historic and current literature describe "cowpox" as a disease with a single etiologic agent. Genotypic data presented herein indicate that CPXV is not a single species, but a composite of several (up to 5 species that can infect cows, humans, and other animals. The practice of naming agents after the host in which the resultant disease manifests obfuscates the true taxonomic relationships of "cowpox" isolates. These data support the elevation of as many as four new species within the traditional "cowpox" group and suggest that both wild and modern vaccine strains of Vaccinia virus are most closely related to CPXV of continental Europe rather than the United Kingdom, the homeland of the vaccine.

  14. The dichotomy of pathogens and allergens in vaccination approaches

    Full Text Available Traditional prophylactic vaccination to prevent illness is the primary objective of many research activities worldwide. The golden age of vaccination began with an approach called variolation in ancient China and the evolution of vaccines still continues today with modern developments such as the production of Gardasil™ against HPV and cervical cancer. The historical aspect of how different forms of vaccination have changed the face of medicine and communities is important as it dictates our future approaches on both a local and global scale. From the eradication of smallpox to the use of an experimental vaccine to save a species, this review will explore these successes in infectious disease vaccination and also discuss a few significant failures which have hampered our efforts to eradicate certain diseases. The second part of the review will explore designing a prophylactic vaccine for the growing global health concern that is allergy. Allergies are an emerging global health burden. Of particular concern is the rise of food allergies in developed countries where 1 in 10 children is currently affected. The formation of an allergic response results from the recognition of a foreign component by our immune system that is usually encountered on a regular basis. This may be a dust-mite or a prawn but this inappropriate immune response can result in a life-time of food avoidance and lifestyle restrictions. These foreign components are very similar to antigens derived from infectious pathogens. The question arises: should the allergy community be focussing on protective measures rather than ongoing therapeutic interventions to deal with these chronic inflammatory conditions? We will explore the difficulties and benefits of prophylactic vaccination against various allergens by means of genetic technology that will dictate how vaccination against allergens could be utilised in the near future.

  15. DNA vaccines

    Gregersen, Jens-Peter

    2001-12-01

    Immunization by genes encoding immunogens, rather than with the immunogen itself, has opened up new possibilities for vaccine research and development and offers chances for new applications and indications for future vaccines. The underlying mechanisms of antigen processing, immune presentation and regulation of immune responses raise high expectations for new and more effective prophylactic or therapeutic vaccines, particularly for vaccines against chronic or persistent infectious diseases and tumors. Our current knowledge and experience of DNA vaccination is summarized and critically reviewed with particular attention to basic immunological mechanisms, the construction of plasmids, screening for protective immunogens to be encoded by these plasmids, modes of application, pharmacokinetics, safety and immunotoxicological aspects. DNA vaccines have the potential to accelerate the research phase of new vaccines and to improve the chances of success, since finding new immunogens with the desired properties is at least technically less demanding than for conventional vaccines. However, on the way to innovative vaccine products, several hurdles have to be overcome. The efficacy of DNA vaccines in humans appears to be much less than indicated by early studies in mice. Open questions remain concerning the persistence and distribution of inoculated plasmid DNA in vivo, its potential to express antigens inappropriately, or the potentially deleterious ability to insert genes into the host cell's genome. Furthermore, the possibility of inducing immunotolerance or autoimmune diseases also needs to be investigated more thoroughly, in order to arrive at a well-founded consensus, which justifies the widespread application of DNA vaccines in a healthy population.

  17. Periodontal vaccine

    Directory of Open Access Journals (Sweden)

    Ranjan Malhotra

    2011-01-01

    Full Text Available Vaccine is the name applied generally to a substance of the nature of dead or attenuated living infectious material introduced into the body with the object of increasing its power to resist or get rid of a disease. Vaccines are generally prophylactic, i.e. they ameliorate the effects of future infection. One such vaccine considered here is the "Periodontal vaccine". Till date, no preventive modality exists for periodontal disease and treatment rendered is palliative. Thus, availability of periodontal vaccine would not only prevent and modulate periodontal disease, but also enhance the quality of life of people for whom periodontal treatment cannot be easily obtained. The aim of the research should be development of a multispecies vaccine targeting the four prime periodontal pathogens, viz. Porphyromonas gingivalis, T. forsythus, T. denticola and A. comitans. Success is still elusive in case of periodontal vaccine due to the complex etiopathogenesis of the disease.

  18. What the world's religions teach, applied to vaccines and immune globulins.

    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

  20. A civilian perspective on ballistic trauma and gunshot injuries

    2010-06-01

    Full Text Available Abstract Background Gun violence is on the rise in some European countries, however most of the literature on gunshot injuries pertains to military weaponry and is difficult to apply to civilians, due to dissimilarities in wound contamination and wounding potential of firearms and ammunition. Gunshot injuries in civilians have more focal injury patterns and should be considered distinct entities. Methods A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed. Results Craniocerebral gunshot injuries are often lethal, especially after suicide attempts. The treatment of non space consuming haematomas and the indications for invasive pressure measurement are controversial. Civilian gunshot injuries to the torso mostly intend to kill; however for those patients who do not die at the scene and are hemodynamically stable, insertion of a chest tube is usually the only required procedure for the majority of penetrating chest injuries. In penetrating abdominal injuries there is a trend towards non-operative care, provided that the patient is hemodynamically stable. Spinal gunshots can also often be treated without operation. Gunshot injuries of the extremities are rarely life-threatening but can be associated with severe morbidity. With the exception of craniocerebral, bowel, articular, or severe soft tissue injury, the use of antibiotics is controversial and may depend on the surgeon's preference. Conclusion The treatment strategy for patients with gunshot injuries to the torso mostly depends on the hemodynamic status of the patient. Whereas hemodynamically unstable patients require immediate operative measures like thoracotomy or laparotomy, hemodynamically stable patients might be treated with minor surgical procedures (e.g. chest tube or even conservatively.

We will discuss the epidemiology, vaccine development, and post-vaccination effects of the hepatitis A and B virus. In addition, we discuss attempts to provide hepatitis D vaccine for the 350 million individuals infected with hepatitis B globally. Given the lack of a hepatitis C vaccine, the many challenges facing the production of a hepatitis C vaccine will be shown, along with current and former vaccination trials. As there is no current FDA-approved hepatitis E vaccine, we will present vaccination data that is available in the rest of the world. Finally, we will discuss the existing challenges and questions facing future endeavors for each of the hepatitis viruses, with efforts continuing to focus on dramatically reducing the morbidity and mortality associated with these serious infections of the liver.

    2015-11-01

    Full Text Available Multiple cornerstones have shaped the history of vaccines, which may contain live attenuated viruses, inactivated organisms/viruses, inactivated toxins, or merely segments of the pathogen that could elicit an immune response.The story began with Hippocrates 400 B.C. with his description of mumps and diphtheria. No further discoveries were recorded until 1100 A.D. when the smallpox vaccine was described. During the 18th century, vaccines for cholera and yellow fever were reported and Edward Jenner, the father of vaccination and immunology, published his work on small pox.The 19th century was a major landmark, with the Germ Theory of disease of Louis Pasteur, the discovery of the germ tubercle bacillus for tuberculosis by Robert Koch, and the isolation of pneumococcus organism by George Miller Sternberg. Another landmark was the discovery of diphtheria toxin by Emile Roux and its serological treatment by Emil Von Behring and Paul Ehrlih. In addition, Pasteur was able to generate the first live attenuated viral vaccine against rabies. Typhoid vaccines were then developed, followed by the plague vaccine of Yersin. At the beginning of World War I, the tetanus toxoid was introduced, followed in 1915 by the pertussis vaccine. In 1974, The Expanded Program of Immunization was established within the WHO for BCG, Polio, DTP, measles, yellow fever and hepatitis B. The year 1996 witnessed the launching of the International AIDS Vaccine Initiative. In 1988, the WHO passed a resolution to eradicate polio by the year 2000 and in 2006; the first vaccine to prevent cervical cancer was developed. In 2010 The Decade of vaccines was launched, and on April 1st 2012, the United Nations launched the shot@Life campaign. In brief, the armamentarium of vaccines continues to grow with more emphasis on safety, availability and accessibility.

    Human Papilloma Viruses are associated with genital carcinoma (of the cervix, anus, vulva, vagina and the penis) as well as with non-genital carcinoma (oropharyngeal carcinoma) and genital warts. In Switzerland two highly efficient and safe vaccines are available. The safety of these vaccines has been repeatedly subject of controversial discussions, however so far post marketing surveillance has always been able to confirm the safety. In Switzerland girls and young women have been offered the HPV vaccination within cantonal programmes since 2008. 2015 the recommendation for the HPV-vaccination for boys and young men was issued, and starting July 1, 2016 they as well will be offered vaccination free of charge within the cantonal programmes. This article discusses the burden of disease, efficacy and safety of the vaccines and presents facts which are important for vaccinating these young people. Specifically, aspects of the decisional capacity of adolescents to consent to the vaccination are presented. Finally, the future perspective with a focus on a new vaccine with an enlarged spectrum of HPV-types is discussed. PMID:27268446

    The global smallpox program is generally presented as the brainchild of a handful of actors from the WHO headquarters in Geneva and at the agency's regional offices. This article attempts to present a more complex description of the drive to eradicate smallpox. Based on the example of India, a major focus of the campaign, it is argued that historians and public health officials should recognize the varying roles played by a much wider range of participants. Highlighting the significance of both Indian and international field officials, the author shows how bureaucrats and politicians at different levels of administration and society managed to strengthen--yet sometimes weaken--important program components. Centrally dictated strategies developed at WHO offices in Geneva and New Delhi, often in association with Indian federal authorities, were reinterpreted by many actors and sometimes changed beyond recognition.

  17. Avoiding dual regulation of the Civilian Radioactive Waste Management Program

    International Nuclear Information System (INIS)

    The Office of Civilian Radioactive Waste Management (RW) has successfully negotiated the issuance of a Department of Energy (DOE) Headquarters Order that provides for exemption of RW from certain DOE directives. This exemption assures precedence of Nuclear Regulatory Commission (NRC) requirements in radiation protection, nuclear safety (including quality assurance), and safeguards and security of nuclear materials. This Order is necessary to avoid the unwarranted cost and potential confusion resulting from dual regulation of RW facilities and activities by DOE and NRC. Development of this Order involved a systematic review of applicable DOE directives and NRC requirements to identify potential overlaps and duplication when applied to the RW program. Following this review and extensive negotiations with appropriate DOE organizations responsible for directives development, this Order was issued as HQ 1321.1 on December 22, 1993

    A new concept of community resilience pertaining to the community's post adversity strength to vulnerability ratio was associated with five determinants: individual resilience, national resilience, well-being, community size, and sense of coherence. The data was collected four months after Israel's war in the Gaza Strip in 2014. Participants were 251 adult civilians living in southern Israel who have recently been threatened by massive missile attacks, and 259 adults living in northern Israel, which has not been under missile fire recently. The investigated variables predicted community resilience, and their effects were mediated by sense of coherence. Results which were similar for both samples were discussed in terms of the nature of resilience and in terms of proximal and distal exposure to war. PMID:26482587

    Full Text Available BACKGROUND: Armed violence is a major public health and humanitarian problem in Iraq. In this descriptive statistical analysis we aimed to describe for the first time Iraqi civilian deaths caused by perpetrators of armed violence during the first 5 years of the Iraq war: over time; by weapon used; by region (governorate; and by victim demographics. METHODS AND FINDINGS: We analyzed the Iraq Body Count database of 92,614 Iraqi civilian direct deaths from armed violence occurring from March 20, 2003 through March 19, 2008, of which Unknown perpetrators caused 74% of deaths (n = 68,396, Coalition forces 12% (n = 11,516, and Anti-Coalition forces 11% (n = 9,954. We analyzed the subset of 60,481 civilian deaths from 14,196 short-duration events of lethal violence to link individual civilian deaths to events involving perpetrators and their methods. One-third of civilian violent death was from extrajudicial executions by Unknown perpetrators; quadratic regression shows these deaths progressively and disproportionately increased as deaths from other forms of violence increased across Iraq's governorates. The highest average number of civilians killed per event in which a civilian died were in Unknown perpetrator suicide bombings targeting civilians (19 per lethal event and Coalition aerial bombings (17 per lethal event. In temporal analysis, numbers of civilian deaths from Coalition air attacks, and woman and child deaths from Coalition forces, peaked during the invasion. We applied a Woman and Child "Dirty War Index" (DWI, measuring the proportion of women and children among civilian deaths of known demographic status, to the 22,066 civilian victims identified as men, women, or children to indicate relatively indiscriminate perpetrator effects. DWI findings suggest the most indiscriminate effects on women and children were from Unknown perpetrators using mortar fire (DWI  = 79 and nonsuicide vehicle bombs (DWI  = 54 and from

  4. The malaria vaccine: seventy years of the great immune hope.

    Desowitz, R S

    2000-06-01

    The cluster of seminal microbiological discoveries at the end of the 19th century through to the first quarter of the 20th century gave rise to the expectation that the control of malaria would be by scientific technology (as opposed to the 'brute force' of bonification/massive engeneering works) and that technology would be immunization by a malaria vaccine. Immunology's foundation was in microbiology and the two related disciplines matured concurrently. Immunization with dead or inactivated microorganisms became immunology's strongest arm, affording protection against many major diseases such as smallpox, anthrax, rabies, yellow fever and tetanus. So why not malaria? In the pre-World War II era there were no chemotherapeutic/prophylactic drugs practical for the control of malaria and a vaccine seemed the easy, rational path to that objective. From 1910 to about 1950 there were numerous attempts in humans and primate and avian models to devise a malaria vaccine. However, it soon became apparent that the malaria parasites, because of their complex, stage-specific antigenic identity as well as their relatively poor immunogenicity, would be much more difficult to use as a vaccine than the bacteria or viruses. There were some experimental successes, but none in humans. PMID:11234327

  5. Tumor vaccines

    International Nuclear Information System (INIS)

    Tumor vaccines have several potential advantages over standard anticancer regiments. They represent highly specific anticancer therapy. Inducing tumor-specific memory T-lymphocytes, they have potential for long-lived antitumor effects. However, clinical trials, in which cancer patients were vaccinated with tumor vaccines, have been so far mainly disappointing. There are many reasons for the inefficiency of tumor vaccines. Most cancer antigens are normal self-molecules to which immune tolerance exists. That is why the population of tumor-specific lymphocytes is represented by a small number of low-affinity T-lymphocytes that induce weak antitumor immune response. Simultaneously, tumors evolve many mechanisms to actively evade immune system, what makes them poorly immunogenic or even tolerogenic. Novel immunotherapeutic strategies are directed toward breaking immune tolerance to tumor antigens, enhancing immunogenicity of tumor vaccines and overcoming mechanisms of tumor escape. There are several approaches, unfortunately, all of them still far away from an ideal tumor vaccine that would reject a tumor. Difficulties in the activation of antitumor immune response by tumor vaccines have led to the development of alternative immunotherapeutic strategies that directly focus on effector mechanisms of immune system (adoptive tumor- specific T-lymphocyte transfer and tumor specific monoclonal antibodies).

  6. Meningococcal Vaccinations.

    Science.gov (United States)

    Crum-Cianflone, Nancy; Sullivan, Eva

    2016-06-01

    Neisseria meningitidis, a gram-negative diplococcal bacterium, is a common asymptomatic nasopharyngeal colonizer that may infrequently lead to invasive disease in the form of meningitis or bacteremia. Six serogroups (A, B, C, W, X and Y) are responsible for the majority of invasive infections. Increased risk of disease occurs in specific population groups including infants, adolescents, those with asplenia or complement deficiencies, and those residing in crowded living conditions such as in college dormitories. The incidence of invasive meningococcal disease varies geographically with some countries (e.g., in the African meningitis belt) having both high endemic disease rates and ongoing epidemics, with annual rates reaching 1000 cases per 100,000 persons. Given the significant morbidity and mortality associated with meningococcal disease, it remains a major global health threat best prevented by vaccination. Several countries have implemented vaccination programs with the selection of specific vaccine(s) based on locally prevalent serogroup(s) of N. meningitidis and targeting population groups at highest risk. Polysaccharide meningococcal vaccines became available over 40 years ago, but are limited by their inability to produce immunologic memory responses, poor immunogenicity in infants/children, hyporesponsiveness after repeated doses, and lack of efficacy against nasopharyngeal carriage. In 1999, the first meningococcal conjugate vaccines were introduced and have been successful in overcoming many of the shortcomings of polysaccharide vaccines. The implementation of meningococcal conjugate vaccination programs in many areas of the world (including the massive campaign in sub-Saharan Africa using a serogroup A conjugate vaccine) has led to dramatic reductions in the incidence of meningococcal disease by both individual and population protection. Progressive advances in vaccinology have led to the recent licensure of two effective vaccines against serogroup B

    Butler, A

    2006-08-01

    Lyon Playfair was born in India but brought up by his uncle in St Andrews. He studied medicine in Glasgow and Edinburgh but never practised as a doctor. Instead he worked for the chemist Thomas Graham in London and then studied for a PhD with Liebig in Germany. While serving on a government commission he became very interested in public health, particularly the control of infectious diseases. In 1883, while a member of parliament, he made a passionate speech in support of a government bill in favour of compulsory vaccination against smallpox. He was violently attacked for his speech in a pamphlet by William White, an adherent of the teachings of the Swedish mystic Emanuel Swedenborg. Playfair died in 1898 and is buried in St Andrews.

  12. Guarding the guardians: Civilian control of nuclear weapons in the United States

    International Nuclear Information System (INIS)

    This book has three separate complementary goals. First, it develops a model to explain how the command and control of nuclear weapons evolves over time. Second, it tells the story of the evolution of one critical aspect of the nuclear command system, the custody of nuclear weapons. Finally, it assesses the general problem of ensuring civilian control over nuclear operations. The focus is on the formation of operational policy. Where to deploy a weapon and at what state of alertness is an operational decision. Part I, The Theory of Civilian Control is divided into three chapters: Civilian control: Principles and problems; Civilian Control: From alerts to war termination; and Explaining changes in civilian control. Part II, The Evolution of Custody Policy has seven chapters: The Atomic Energy Act and the origin of assertive control, 1945-1947; The first test of assertive civilian control, 1948-1949; The breach in assertive control, 1950-1952; Assertive control becomes delegative control, 1953-1958; The resurgence of assertive control, 1959-1962; The cycle continues, 1963-1990; and Conclusion: The future of civilian control

    Antigens located in the midgut of the tick are hidden from the host's immune system. Egg production of ticks can be reduced when ticks are fed on animals vaccinated with midgut antigens of the tick, and a subunit vaccine formulated with the recombinant antigen Bm86 is now available that can reduce the number of ticks infesting cattle grazing on pasture. Midgut antigens used in vaccines against insects that transmit pathogenic organisms to humans have not been as effective in reducing insect fecundity and an alternative approach may be necessary. Transmission-blocking vaccines directed at interfering with the vector-pathogen interaction could result in loss of vector competence and block the spread of disease-causing organisms. PMID:10198800

    Full Text Available Streptococcus pneumoniae (SP is a gram-positive bacterium with more than 90 known serotypes causing around 11% of all deaths worldwide in children aged 1-59 months. A new era in prevention of SP-related diseases started in at the beginning of 2000s when a 7-valent pneumococcal conjugate vaccine (PCV7 was recommended as the vaccine of choice in pediatric age. PCV7 dramatically reduced invasive pneumococcal diseases (IPD among children with indirect effects noted among other age groups as well. However, thanks to a strict surveillance network, an increase in non-vaccine serotypes (NVTs causing IPD was noted worldwide and in late 2000s a new second generation vaccine (13-valent pneumococcal conjugate vaccine-PCV13 with an expanded serotype coverage was licensed. Due to the lack of solid effectiveness data, up to know it is difficult to predict how the composition of NVTs will change after the large-scale introduction of PCV13 or whether the characteristics of the serotypes will change. Long-term surveillance of both IPD, pneumonia, acute otitis media and carriage will be crucial to ascertain whether these second generation vaccines are having the desired effect of reducing the incidence of diseases in the long term. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

  18. Military and civilian burn injuries during armed conflicts.

    Science.gov (United States)

    Atiyeh, B S; Gunn, S W A; Hayek, S N

    2007-12-31

    Burn injury is a ubiquitous threat in the military environment, and war burns have been described for more than 5,000 years of written history. Fire was probably utilized as a weapon long before that. With the ever-increasing destructive power and efficiency of modern weapons, casualties, both fatal and non-fatal, are reaching new highs, particularly among civilians who are becoming the major wartime targets in recent wars, accounting for most of the killed and wounded. Even though medical personnel usually believe that a knowledge of weaponry has little relevance to their ability to effectively treat injuries and that it may in some way be in conflict with their status, accorded under the Geneva and Hague treaties, it is imperative that they know how weapons are used and understand their effects on the human body. The present review explores various categories of weapons of modern warfare that are unfamiliar to most medical and paramedical personnel responsible for burn treatment. The mechanisms and patterns of injury produced by each class of weapons are examined so that a better understanding of burn management in a warfare situation may be achieved. PMID:21991098

  19. Civilian Power from Space in the Early 21st Century

    Energy Technology Data Exchange (ETDEWEB)

    Hyde, R; Ishikawa, M; Wood, L

    2003-06-01

    If power beamed from space is to be become widely used on Earth in the first half of the 21St century, several thus-far-persistent impediments must be obviated, including threshold effects and problematic aspects of cost, availability, reliability, hazards and environmental impacts. We sketch a generally-applicable route to doing so, noting key enabling technologies and practical features. Likely-essential features of any successful strategy include vigorous, systematic leveraging of all intrinsic features of space-derived power, e.g., addressing marginal, high-value-added markets for electric power in space- and time-agile manners to conveniently provide power-upon-demand, and incrementally ''wedging'' into ever-larger markets with ever more cost-efficient generations and scales of technology. We suggest that no prudent strategic plan will rely upon large-scale, long-term public subsidies--fiscal, regulatory, etc.--with their attendant ''sovereign risks'' and interminable delays, and that plan-essential governmental support likely will be limited to early feasibility demonstrations, provision of threshold technologies and a rational, competition-neutral licensing environment. If salient realities are uniformly respected and accessible technologies are intelligently leveraged, electricity derived from space-sourced power-beams may come into significant civilian use during the latter part of the first quarter of this century, and may become widely used by the half-century point.

  20. Neutron radiography for maintenance inspection of military and civilian aircraft

    International Nuclear Information System (INIS)

    As part of a program to develop new and advanced nondestructive inspection techniques, a series of projects has been conducted to develop and evaluate neutron radiography as a nondestructive inspection tool. A major portion of this effort has been directed toward the application of neutron radiography as a maintenance inspection tool for military and civilian aircraft. The availability of 252Cf as a neutron source has enabled the use of neutron-radiography systems in normal maintenance environments for the inspection of flight-line aircraft with a minimum of interference. Neutron radiography has been demonstrated to be a powerful nondestructive inspection tool for a variety of applications involving the detection of organic or non-metallic compounds. Its ability to detect surface and subsurface corrosion in aircraft structure is unmatched by any other inspection technique. This capability of detecting corrosion without component disassembly is particularly significant when corrosion is hidden behind thick metallic structural members. The neutron radiographic technique has been applied successfully to detect corrosion in wing tanks, rear stabilators, aft spar, starboard and port wing, rudder, fuselage skin, and nose landing gears of a variety of fixed-wind aircraft, as well as rotary blades and rotary tail flaps of heliocopters

  1. Office of Civilian Radioactive Waste Management annual report to Congress

    International Nuclear Information System (INIS)

    This seventh Annual Report to Congress by the Office of Civilian Radioactive Waste Management (OCRWM) describes activities and expenditures of the Office during fiscal years (FY) 1989 and 1990. In November 1989, OCRWM is responsible for disposing of the Nation's spent nuclear fuel and high-level radioactive waste in a manner that protects the health and safety of the public and the quality of the environment. To direct the implementation of its mission, OCRWM has established the following objectives: (1) Safe and timely disposal: to establish as soon as practicable the ability to dispose of radioactive waste in a geologic repository licensed by the NRC. (2) Timely and adequate waste acceptance: to begin the operation of the waste management system as soon as practicable in order to obtain the system development and operational benefits that have been identified for the MRS facility. (3) Schedule confidence: to establish confidence in the schedule for waste acceptance and disposal such that the management of radioactive waste is not an obstacle to the nuclear energy option. (4) System flexibility: to ensure that the program has the flexibility necessary for adapting to future circumstances while fulfilling established commitments. To achieve these objectives, OCRWM is developing a waste management system consisting of a geologic repository for permanent disposed deep beneath the surface of the earth, a facility for MRS, and a system for transporting the waste

  2. Office of Civilian Radioactive Waste Management annual report to Congress

    International Nuclear Information System (INIS)

    This is the fifth Annual Report to Congress by the Office of Civilian Radioactive Waste Management (OCRWM). The report covers the activities and expenditures of OCRWM during fiscal year 1987, which ended on September 30, 1987. The activities and accomplishments of OCRWM during fiscal year 1987 are discussed in chapters 1 through 9 of this report. The audited financial statements of the Nuclear Waste Fund are provided in chapter 10. Since the close of the fiscal year, a number of significant events have occurred. Foremost among them was the passage of the Nuclear Waste Policy Amendments Act of 1987 (Amendments Act) on December 21, 1987, nearly 3 months after the end of the fiscal year covered by this report. As a result, some of the plans and activities discussed in chapters 1 through 9 are currently undergoing significant change or are being discontinued. Most prominent among the provisions of the Amendments Act is the designation of Yucca Mountain, Nevada, as the only candidate first repository site to be characterized. Therefore, the site characterization plans for Deaf Smith, Texas, and Hanford, Washington, discussed in chapter 3, will not be issued. The refocusing of the waste management program under the Amendments Act is highlighted in the epilogue, chapter 11. 68 refs., 7 figs., 7 tabs

    Biomechanical quantification of projectile penetration using experimental head models can enhance the understanding of civilian ballistic brain injury and advance treatment. Two of the most commonly used handgun projectiles (25-cal, 275 m/s and 9 mm, 395 m/s) were discharged to spherical head models with gelatin and Sylgard simulants. Four ballistic pressure transducers recorded temporal pressure distributions at 308kHz, and temporal cavity dynamics were captured at 20,000 frames/second (fps) using high-speed digital video images. Pressures ranged from 644.6 to -92.8 kPa. Entry pressures in gelatin models were higher than exit pressures, whereas in Sylgard models entry pressures were lower or equivalent to exit pressures. Gelatin responded with brittle-type failure, while Sylgard demonstrated a ductile pattern through formation of micro-bubbles along projectile path. Temporary cavities in Sylgard models were 1.5-2x larger than gelatin models. Pressures in Sylgard models were more sensitive to projectile velocity and diameter increase, indicating Sylgard was more rate sensitive than gelatin. Based on failure patterns and brain tissue rate-sensitive characteristics, Sylgard was found to be an appropriate simulant. Compared with spherical projectile data, full-metal jacket (FMJ) projectiles produced different temporary cavity and pressures, demonstrating shape effects. Models using Sylgard gel and FMJ projectiles are appropriate to enhance understanding and mechanisms of ballistic brain injury.

    Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system, which has been associated with several vaccines such as rabies, diphtheria-tetanus-polio, smallpox, measles, mumps, rubella, Japanese B encephalitis, pertussis, influenza, and the Hog vaccine. Here, we presented a case of 12-year-old child who suffered from ADEM three weeks after hepatitis B vaccination. He was admitted to our hospital with symptoms of weakness of limbs, high fever, and alteration of consciousness. Some abnormalities were also found in CSF. Treatment with high-dose corticosteroids and intravenous immunoglobulin had significant effect, with marked improvement of the clinical symptoms and the results of CSF. The findings of MRI also detected some abnormal lesions located in both brain and spinal cord. The clinical features, the findings of CSF and MRI, and therapeutic effect may contribute to such diagnosis of ADEM. PMID:27478662

    In 1914, in the former Portuguese colony of Goa, India, the physician António Joaquim Vás announced the discovery of a wonderful treatment for smallpox, entailing clinical application of seeds from the bananeira brava (Heliconia biabi Sw.m.), a plant remedy allegedly derived from Indian medical practices. The present article explores the circumstances surrounding the successes and failures of this discovery. The concept of scientific translation is used to interpret the transformation of bananeira brava seeds into an early twentieth-century remedy for smallpox. This transfer from indigenous use to scientific therapeutic constitutes the creation of a quasi-medicine, that is, a case of 'medium translation'. Although these seeds occupy a problematic place within the program of scientific translation, they enjoyed active circulation within science and remained a part of medical practices for combating smallpox.

    In 1914, in the former Portuguese colony of Goa, India, the physician António Joaquim Vás announced the discovery of a wonderful treatment for smallpox, entailing clinical application of seeds from the bananeira brava (Heliconia biabi Sw.m.), a plant remedy allegedly derived from Indian medical practices. The present article explores the circumstances surrounding the successes and failures of this discovery. The concept of scientific translation is used to interpret the transformation of bananeira brava seeds into an early twentieth-century remedy for smallpox. This transfer from indigenous use to scientific therapeutic constitutes the creation of a quasi-medicine, that is, a case of 'medium translation'. Although these seeds occupy a problematic place within the program of scientific translation, they enjoyed active circulation within science and remained a part of medical practices for combating smallpox.

    Mucosal vaccination offers great advantage for inducing protective immune response to prevent viral transmission and dissemination. Here, we report our findings of a head-to-head comparison of two viral vectors modified vaccinia Ankara (MVA) and a novel replication-competent modified vaccinia Tian Tan (MVTT) for inducing neutralizing antibodies (Nabs) via intramuscular and mucosal vaccinations in mice. MVTT is an attenuated variant of the wild-type VTT, which was historically used as a smallpox vaccine for millions of Chinese people. The spike glycoprotein (S) of SARS-CoV was used as the test antigen after the S gene was constructed in the identical genomic location of two vectors to generate vaccine candidates MVTT-S and MVA-S. Using identical doses, MVTT-S induced lower levels ( approximately 2-3-fold) of anti- SARS-CoV neutralizing antibodies (Nabs) than MVA-S through intramuscular inoculation. MVTT-S, however, was capable of inducing consistently 20-to-100-fold higher levels of Nabs than MVA-S when inoculated via either intranasal or intraoral routes. These levels of MVTT-S-induced Nab responses were substantially (approximately 10-fold) higher than that induced via the intramuscular route in the same experiments. Moreover, pre-exposure to the wild-type VTT via intranasal or intraoral route impaired the Nab response via the same routes of MVTT-S vaccination probably due to the pre-existing anti-VTT Nab response. The efficacy of intranasal or intraoral vaccination, however, was still 20-to-50-fold better than intramuscular inoculation despite the subcutaneous pre-exposure to wild-type VTT. Our data have implications for people who maintain low levels of anti-VTT Nabs after historical smallpox vaccination. MVTT is therefore an attractive live viral vector for mucosal vaccination.

    2007-01-01

    Traumatic brain injury (TBI) is a major health problem in civilian, military, and veteran populations. Individuals experiencing moderate to severe TBI require a continuum of care involving acute hospitalization and postacute rehabilitation, including community reintegration and, one would hope, a return home to function as a productive member of the community. In the military, the goal is to help individuals with TBI return to active duty or make an optimal return to civilian life if the extent of their injuries necessitates a "medical board" discharge. Whether civilian, military, or veteran with TBI, individuals who move beyond the need to live in a facility must be reintegrated back into the community. This article discusses four treatment models for community reintegration, reviews treatment standardization and outcome issues, and describes a manualized rehabilitation pilot program designed to provide community reintegration and return to duty/work for civilians, veterans, and military personnel with TBI.

    Selection of immunizations should be based on requirements and on risk of infection. According to the International Health Regulations, many countries require yellow fever vaccination and proof thereof as the International Certificate of vaccination. Additionally selected countries require proof of vaccination against cholera and meningococcal disease. A consultation for travel health advice is always an opportunity to ascertain that routine immunizations have been performed. Recommended immunizations often are more important for traveller's health than the required or routine ones. The most frequent vaccine preventable infection in non-immune travellers to developing countries is hepatitis A with an average incidence rate of 0.3% per month; in high risk backpackers or foreign-aid-volunteers this rate is 2.0%. Many immunizations are recommended for special risk groups only: there is a growing tendency in many countries to immunize all young travellers to developing countries against hepatitis B, as it is uncertain who will voluntarily or involuntarily get exposed. The attack rate of influenza in intercontinental travel is estimated to be 1%. Immunity against poliomyelitis remains essential for travel to Africa and parts of Asia. Many of the 0.2-0.4% who experience an animal bite are at risk of rabies. Typhoid fever is diagnosed with an incidence rate of 0.03% per month among travellers to the Indian subcontinent, North and West Africa (except Tunisia), and Peru, elsewhere this rate is 10-fold lower. Meningococcal disease, Japanese encephalitis, cholera and tuberculosis have been reported in travellers, but these infections are rare in this population. Although no travel health vaccine is cost beneficial, most professionals will offer protection against the frequent risks, while most would find it ridiculous to use all available vaccines in every traveller. It is essentially an arbitrary decision made on the risk level one wishes to recommend protection--but the

    1994-05-01

    Some have argued that the vaccine against malaria developed by Manuel Pattaroyo, a Colombian scientist, is being tested prematurely in humans and that it is unlikely to be successful. While the Pattaroyo vaccine has been shown to confer protection against the relatively mild malaria found in Colombia, doubts exist over whether it will be effective in Africa. Encouraging first results, however, are emerging from field tests in Tanzania. The vaccine triggered a strong new immune response, even in individuals previously exposed to malaria. Additional steps must be taken to establish its impact upon mortality and morbidity. Five major trials are underway around the world. The creator estimates that the first ever effective malaria vaccine could be available for widespread use within five years and he has no intention of securing a patent for the discovery. In another development, malaria specialists from 35 African countries convened at an international workshop in Zimbabwe to compare notes. Participants disparaged financial outlays for the fight against malaria equivalent to 2% of total AIDS funding as insufficient; noted intercountry differences in prevention, diagnosis, and treatment; and found information exchange between anglophone and francophone doctors to be generally poor.

    To combat variola virus in bioterrorist attacks, it is desirable to develop a noninvasive vaccine. Based on the vaccinia Tiantan (VTT) strain, which was historically used to eradicate the smallpox in China, we generated a modified VTT (MVTT(ZCI)) by removing the hemagglutinin gene and an 11,944bp genomic region from HindIII fragment C2L to F3L. MVTT(ZCI) was characterized for its host cell range in vitro and preclinical safety and efficacy profiles in mice. Despite replication-competency in some cell lines, unlike VTT, MVTT(ZCI) did not cause death after intracranial injection or body weight loss after intranasal inoculation. MVTT(ZCI) did not replicate in mouse brain and was safe in immunodeficient mice. MVTT(ZCI) induced neutralizing antibodies via the intranasal route of immunization. One time intranasal immunization protected animals from the challenge of the pathogenic vaccinia WR strain. This study established proof-of-concept that the attenuated replicating MVTT(ZCI) may serve as a safe noninvasive smallpox vaccine candidate.

    Data on adult immunization coverage at the state level and for LGBT Americans in particular are sparse. This study reports the results of a 2012 Lexington-Fayette County, Kentucky, community health assessment's results asking about eight adult vaccinations among 218 lesbian, gay, bisexual, and transgendered (LGBT) respondents. Researchers collected data using an online survey distributed through LGBT social media, posters, and LGBT print media. The LGBT sample largely matches the demographics of the county as a whole except this group reports higher level of education and fewer uninsured individuals. Among LGBT respondents, immunization prevalence reaches 68.0% (annual Influenza), 65.7% (Hepatitis B), 58.8% (Chickenpox/Varicella), 55.9% (Hepatitis A), 41.2% (Smallpox), and 25.8% (Pneumonia). Among respondents who are currently within the recommended 19-26 years age range for the Human Papillomavirus (HPV) vaccine, the LGBT females are less likely to report receiving the vaccine (15.4%) compared to the national coverage percentage of 34.5%. Males, however, are more likely to have received the vaccine (10.3%) than the national percentage of 2.3%. The small number of LGBT seniors in the study report a much higher prevalence of the Shingles (Herpes Zoster) vaccines than for U.S. seniors 60 and older (71.4% compared to 20.1% nationally). LGBT respondents report higher percentages of adult vaccination. PMID:26930365

    Civilian employees, contractors, and private community clinicians are increasingly providing health treatment to currently serving and former military personnel. This study addresses recent calls for evidence-based information to assist civilian practitioners in understanding the perspectives of their military clients. To this end, the self-reported character strengths of military personnel were elicited as an operationalized expression of their underlying personal values that shape their perspectives and conduct as soldiers. Specifically, Australian Army Special Forces operators and support personnel (N = 337) were asked to rank themselves on 24 character strengths. The three character strengths of integrity, teamworker, and good judgment were ranked significantly above random assignment. Nearly all the respondents (84%) gave a top rank to at least one of these character strengths. Differences between the operators and support personnel were modest. Results are discussed with respect to establishing an effective relationship between military clients and civilian health care practitioners. PMID:27612343

Part of this responsibility includes providing for the application of both domestic and international safeguards on nuclear material at facilities of the Civilian Waste Management System. While detailed safeguards requirements for these disposal facilities have yet to be established, once established, they could impact facility design. Accordingly, OCRWM has participated in efforts to develop safeguards approaches for geologic repositories and will continue to participate actively with the Nuclear Regulatory Commission (NRC), International Atomic Energy Agency (IAEA), as well as other Department of Energy (DOE) Offices in efforts to resolve safeguards issues related to spent fuel disposal, to minimize any potential design impacts and to support effective nuclear material safeguards. The following paper discusses current plants and issues related to the application of safeguards to the Civilian Radioactive Waste Management System (CRWMS)

    Millions of adults are vaccinated annually against the seasonal influenza virus. An undetermined number of individuals will develop adverse events to the influenza vaccination. Those who suffer substantiated vaccine injuries, disabilities, and aggravated conditions may file a timely, no-fault and no-cost petition for financial compensation under the National Vaccine Act in the Vaccine Court. The elements of a successful vaccine injury claim are described in the context of a claim showing the seasonal influenza vaccination was the cause of Guillain-Barré syndrome.

    @@ Anew method of immunization was discovered in the early 1990s. Several research groups independently demonstrated that direct inoculation of DNA plasmids coding for a specific protein antigen could elicit immune responses against that antigen[1-4].Since in theory the mRNA molecules also have the potential to be translated into the protein antigen, this vaccination approach was officially named by WHO as the nucleic acid vaccination even though the term DNA vaccine has been used more commonly in the literature. This novel approach is considered the fourth generation of vaccines after live attenuated vaccines, killed or inactivated vaccines and recombinant protein based subunit vaccines.

  10. Development of eczema vaccinatum in atopic mouse models and efficacy of MVA vaccination against lethal poxviral infection.

    Jarmila Knitlova

    Full Text Available Smallpox vaccine based on live, replicating vaccinia virus (VACV is associated with several potentially serious and deadly complications. Consequently, a new generation of vaccine based on non-replicating Modified vaccinia virus Ankara (MVA has been under clinical development. MVA seems to induce good immune responses in blood tests, but it is impossible to test its efficacy in vivo in human. One of the serious complications of the replicating vaccine is eczema vaccinatum (EV occurring in individuals with atopic dermatitis (AD, thus excluding them from all preventive vaccination schemes. In this study, we first characterized and compared development of eczema vaccinatum in different mouse strains. Nc/Nga, Balb/c and C57Bl/6J mice were epicutaneously sensitized with ovalbumin (OVA or saline control to induce signs of atopic dermatitis and subsequently trans-dermally (t.d. immunized with VACV strain Western Reserve (WR. Large primary lesions occurred in both mock- and OVA-sensitized Nc/Nga mice, while they remained small in Balb/c and C57Bl/6J mice. Satellite lesions developed in both mock- and OVA-sensitized Nc/Nga and in OVA-sensitized Balb/c mice with the rate 40-50%. Presence of mastocytes and eosinophils was the highest in Nc/Nga mice. Consequently, we have chosen Nc/Nga mice as a model of AD/EV and tested efficacy of MVA and Dryvax vaccinations against a lethal intra-nasal (i.n. challenge with WR, the surrogate of smallpox. Inoculation of MVA intra-muscularly (i.m. or t.d. resulted in no lesions, while inoculation of Dryvax t.d. yielded large primary and many satellite lesions similar to WR. Eighty three and 92% of mice vaccinated with a single dose of MVA i.m. or t.d., respectively, survived a lethal i.n. challenge with WR without any serious illness, while all Dryvax-vaccinated animals survived. This is the first formal prove of protective immunity against a lethal poxvirus challenge induced by vaccination with MVA in an atopic organism.

    The limited number of oral vaccines currently approved for use in humans and veterinary species clearly illustrates that development of efficacious and safe oral vaccines has been a challenge not only for fish immunologists. The insufficient efficacy of oral vaccines is partly due to antigen breakdown in the harsh gastric environment, but also to the high tolerogenic gut environment and to inadequate vaccine design. In this review we discuss current approaches used to develop oral vaccines fo...

    Full Text Available In mid-April of 1958 the Government of Pakistan summoned the press to announce a grave need for international aid to cope with smallpox and cholera epidemics in East Pakistan. In response, and with the backing of the US State Department, Dr. Alexander D. Langmuir, chief epidemiologist of the CDC, led a team of epidemiologists to assist authorities in Dacca strengthen their immunization programs. Langmuir's superiors hoped for a Cold War advantage, but he saw an opportunity for trainees in the Epidemic Intelligence Service to learn about public health in a developing country. Langmuir later described the episode as a "wild and wondrous ride," but it had been more like a nightmare: the East Pakistan health department had collapsed; a popular movement had taken over vaccination and squandered vaccine supplies; hostile journalists had questioned the Americans' deeper motives; and a professional rivalry opened between the Americans and a British epidemiologist named Aidan Cockburn. By the time the epidemic subsided in July 1958, 30 million Bengalis had been vaccinated for smallpox but another 20,000 had succumbed to the disease. This episode was CDC's first sustained foreign intervention, a precursor to its extensive role in the 1970s helping WHO eradicate smallpox from Bangladesh.Em meados de abril de 1958, o Governo do Paquistão convocou a imprensa para anunciar a urgente necessidade de auxílio internacional para lidar com epidemias de varíola e cólera no Paquistão Oriental.

    2015-06-19

    Typhoid vaccination is an important component of typhoid fever prevention and control, and is recommended for public health programmatic use in both endemic and outbreak settings. We reviewed experiences with various vaccination strategies using the currently available typhoid vaccines (injectable Vi polysaccharide vaccine [ViPS], oral Ty21a vaccine, and injectable typhoid conjugate vaccine [TCV]). We assessed the rationale, acceptability, effectiveness, impact and implementation lessons of these strategies to inform effective typhoid vaccination strategies for the future. Vaccination strategies were categorized by vaccine disease control strategy (preemptive use for endemic disease or to prevent an outbreak, and reactive use for outbreak control) and vaccine delivery strategy (community-based routine, community-based campaign and school-based). Almost all public health typhoid vaccination programs used ViPS vaccine and have been in countries of Asia, with one example in the Pacific and one experience using the Ty21a vaccine in South America. All vaccination strategies were found to be acceptable, feasible and effective in the settings evaluated; evidence of impact, where available, was strongest in endemic settings and in the short- to medium-term. Vaccination was cost-effective in high-incidence but not low-incidence settings. Experience in disaster and outbreak settings remains limited. TCVs have recently become available and none are WHO-prequalified yet; no program experience with TCVs was found in published literature. Despite the demonstrated success of several typhoid vaccination strategies, typhoid vaccines remain underused. Implementation lessons should be applied to design optimal vaccination strategies using TCVs which have several anticipated advantages, such as potential for use in infant immunization programs and longer duration of protection, over the ViPS and Ty21a vaccines for typhoid prevention and control.

    Worldwide, large proportion i.e., 37% of deaths due to diarrhea in young children is attributed to rotavirus. A monovalent P1A[8] G1 vaccine and a pentavalent bovine-human reassortant vaccine human rotavirus vaccine had shown good clinical efficacy without any increase in intussusception among vaccine recipients. WHO recommends that the first dose of rotavirus vaccine should be administered to infants up to age of 6-15 weeks irrespective of the prior history of rotavirus infection and the maximum age for administering the last dose of the vaccine should be 32 weeks. Booster doses are not recommended. The current update reviews the issues related to rotavirus vaccines and their usages like milestones in the development of rotavirus vaccines, concerns regarding their efficacy and cost-effectiveness, immunity after natural infection, potential for changes in virus strains, current recommendations, post marketing surveillance, and future challenges and scope for further research regarding rotavirus vaccines.

  1. Prospective surveillance for cardiac adverse events in healthy adults receiving modified vaccinia Ankara vaccines: a systematic review.

    Directory of Open Access Journals (Sweden)

    Marnie L Elizaga

    Full Text Available BACKGROUND: Vaccinia-associated myo/pericarditis was observed during the US smallpox vaccination (DryVax campaign initiated in 2002. A highly-attenuated vaccinia strain, modified vaccinia Ankara (MVA has been evaluated in clinical trials as a safer alternative to DryVax and as a vector for recombinant vaccines. Due to the lack of prospectively collected cardiac safety data, the US Food and Drug Administration required cardiac screening and surveillance in all clinical trials of MVA since 2004. Here, we report cardiac safety surveillance from 6 phase I trials of MVA vaccines. METHODS: Four clinical research organizations contributed cardiac safety data using common surveillance methods in trials administering MVA or recombinant MVA vaccines to healthy participants. 'Routine cardiac investigations' (ECGs and cardiac enzymes obtained 2 weeks after injections of MVA or MVA-HIV recombinants, or placebo-controls, and 'Symptom-driven cardiac investigations' are reported. The outcome measure is the number of participants who met the CDC-case definition for vaccinia-related myo/pericarditis or who experienced cardiac adverse events from an MVA vaccine. RESULTS: Four hundred twenty-five study participants had post-vaccination safety data analyzed, 382 received at least one MVA-containing vaccine and 43 received placebo; 717 routine ECGs and 930 cardiac troponin assays were performed. Forty-five MVA recipients (12% had additional cardiac testing performed; 22 for cardiac symptoms, 19 for ECG/laboratory changes, and 4 for cardiac symptoms with an ECG/laboratory change. No participant had evidence of symptomatic or asymptomatic myo/pericarditis meeting the CDC-case definition and judged to be related to an MVA vaccine. CONCLUSIONS: Prospective surveillance of MVA recipients for myo/pericarditis did not detect cardiac adverse reactions in 382 study participants.

    2011-12-01

    Full Text Available U.S. officials have recently claimed that the CIA has sharply reduced the number of civilian casualties resulting from covert Predator and Reaper drone strikes in the Taliban-controlled agencies of Northwest Pakistan. Critics, especially in Pakistan, along with human rights NGOs have, however, questioned these claims. This article examines independent databases tracking the drone strikes and finds that there is significant support for the U.S. officials’ claims, or at least for their more moderate assertions. It also briefly reviews the explanations that have been offered for the declining civilian death toll from drone strikes. It shows that there is reason to believe that this development is the deliberate result of adjustments to CIA targeting procedures and improvements in spy networks and technology, and thus is likely to prove broadly sustainable at least for the immediate future.

  5. The use of civilian-type GPS receivers by the military and their vulnerability to jamming

    Directory of Open Access Journals (Sweden)

    Ludwig Combrinck

    2012-05-01

    Full Text Available We considered the impact of external influences on a GPS receiver and how these influences affect the capabilities of civilian-type GPS receivers. A standard commercial radio frequency signal generator and passive GPS antenna were used to test the sensitivity of GPS to intentional jamming; the possible effects of the terrain on the propagation of the jamming signal were also tested. It was found that the high sensitivity of GPS receivers and the low strength level of GPS satellite signals combine to make GPS receivers very vulnerable to intentional jamming or unintentional radio frequency interference. Terrain undulation was used to shield GPS antennas from the direct line-of-sight of the jamming antenna and this indicated that terrain characteristics can be used to mitigate the effects of jamming. These results illuminate the vulnerability of civilian-type GPS receivers to the possibility and the ease of disablement and establish the foundation for future work.

  6. Feasibility of Burning Civilian Grade Pu in the Modular HTR with Th Fuel Cycle

    Institute of Scientific and Technical Information of China (English)

    许云林; 经荥清

    2001-01-01

    The Modular High Temperature Gas-Cooled Reactor (HTR) can be usedto burn plutonium fuel to reduce Pu stockpiles because of its inherent safety characteristics and ability to burn a variety of fuel mixtures. The equilibrium core is calculated and analyzed for Pu enriched fuel. Fuel spheres with 7 g heavy metal including the civilian grade Pu and thorium are loaded into the reactor. An enrichment of 11% is chosen to provide the desired equilibrium core reactivity. The fuel and moderator temperature coefficients are both negative. The maximum fuel element temperature during normal operation and during a loss of coolant accident is less than 1500 ℃. 92% of 239Pu will be burnt during nomal operation. Therefore, a thorium fuel cycle in the modular HTR is an effective method for burning civilian grade plutonium.

    2016-07-01

    Full Text Available In 2007, the United States– Food and Drug Administration (FDA issued guidance concerning animal models for testing the efficacy of medical countermeasures against variola virus (VARV, the etiologic agent for smallpox. Ectromelia virus (ECTV is naturally-occurring and responsible for severe mortality and morbidity as a result of mousepox disease in the murine model, displaying similarities to variola infection in humans. Due to the increased need of acceptable surrogate animal models for poxvirus disease, we have characterized ECTV infection in the BALB/c mouse. Mice were inoculated intranasally with a high lethal dose (125 PFU of ECTV, resulting in complete mortality 10 days after infection. Decreases in weight and temperature from baseline were observed eight to nine days following infection. Viral titers via quantitative polymerase chain reaction (qPCR and plaque assay were first observed in the blood at 4.5 days post-infection and in tissue (spleen and liver at 3.5 days post-infection. Adverse clinical signs of disease were first observed four and five days post-infection, with severe signs occurring on day 7. Pathological changes consistent with ECTV infection were first observed five days after infection. Examination of data obtained from these parameters suggests the ECTV BALB/c model is suitable for potential use in medical countermeasures (MCMs development and efficacy testing.

  2. Investigating the Relationship Between Drone Warfare and Civilian Casualties in Gaza

    Directory of Open Access Journals (Sweden)

    Dr. Ann Rogers

    2014-12-01

    Full Text Available Unmanned aerial vehicles (UAVs, better known as drones, are increasingly touted as ‘humanitarian’ weapons that contribute positively to fighting just wars and saving innocent lives. At the same time, civilian casualties have become the most visible and criticized aspect of drone warfare. It is argued here that drones contribute to civilian casualties not in spite of, but because of, their unique attributes. They greatly extend war across time and space, pulling more potential threats and targets into play over long periods, and because they are low-risk and highly accurate, they are more likely to be used. The assumption that drones save lives obscures a new turn in strategic thinking that sees states such as Israel and the US rely on large numbers of small, highly discriminating attacks applied over time to achieve their objectives. This examination of Israel’s 2014 war in Gaza argues that civilian casualties are not an unexpected or unintended consequence of drone warfare, but an entirely predictable outcome.

  3. International Cooperation to Minimize the Use of Highly Enriched Uranium in Civilian Applications

    International Nuclear Information System (INIS)

    The U.S. Department of Energy’s National Nuclear Security Administration’s Global Threat Reduction Initiative (GTRI) works cooperatively with international partners worldwide to minimize the use of highly enriched uranium (HEU) in civilian applications. To achieve this mission, which was highlighted in the Communiqué of the 2012 Seoul Nuclear Security Summit, GTRI implements two key HEU minimization efforts: the Reactor Conversion Program and the Mo-99 Program. Under the Reactor Conversion program, GTRI cooperates with dozens of international partners to convert HEU research reactors to operate with low enriched uranium (LEU) fuel and develops new LEU fuel technologies that will be used to convert higher-power, unique reactors. Under the Mo-99 program, GTRI cooperates with international molybdenum-99 (Mo-99) producers to convert their production processes from HEU to LEU targets and cooperates with domestic partners to establish a reliable non-HEU-based Mo-99 production capability in the United States. These critical efforts to minimize, and where possible eliminate, the use of and demand for HEU in civilian applications worldwide have received unprecedented political and financial support in recent years. As the programs begin to address facilities that are increasingly challenging from a technical perspective, an increasing level of political and financial support will be vital to ensuring that the programs succeed and that civilian facilities around the world can continue to fulfill critical scientific missions while greatly reducing the risk that HEU could fall into the wrong hands and be used for malevolent purposes.

  6. Mathematical modeling provides kinetic details of the human immune response to vaccination

    Full Text Available With major advances in experimental techniques to track antigen-specific immune responses many basic questions on the kinetics of virus-specific immunity in humans remain unanswered. To gain insights into kinetics of T and B cell responses in human volunteers we combine mathematical models and experimental data from recent studies employing vaccines against yellow fever and smallpox. Yellow fever virus-specific CD8 T cell population expanded slowly with the average doubling time of 2 days peaking 2.5 weeks post immunization. Interestingly, we found that the peak of the yellow fever-specific CD8 T cell response is determined by the rate of T cell proliferation and not by the precursor frequency of antigen-specific cells as has been suggested in several studies in mice. We also found that while the frequency of virus-specific T cells increases slowly, the slow increase can still accurately explain clearance of yellow fever virus in the blood. Our additional mathematical model describes well the kinetics of virus-specific antibody-secreting cell and antibody response to vaccinia virus in vaccinated individuals suggesting that most of antibodies in 3 months post immunization are derived from the population of circulating antibody-secreting cells. Taken together, our analysis provides novel insights into mechanisms by which live vaccines induce immunity to viral infections and highlight challenges of applying methods of mathematical modeling to the current, state-of-the-art yet limited immunological data.

    The research of reactions to disasters is uncommon. Moreover, most studies target a specific population, whether civilians or professionals. The aim of this study was to compare the reactions of hospital personnel and civilians after exposure to a unique disaster that combines natural and nuclear disaster. A matching sample of nurses and civilians was compared using a brief questionnaire tapping into posttraumatic stress disorder (PTSD) symptoms, subjective health, perceived coping, life satisfaction, and meaning in life. The results revealed that the nurses had a lower level of PTSD symptoms and higher self-rated health, life satisfaction, and perceived coping in comparison with the civilians. These results are discussed in light of work characteristics that include exposure to traumatic events as part of their work and coping that is partially based on training.

    1991-01-01

    Recombinant virus vaccines that express a limited number of epitopes are currently being developed to prevent disease by changing the relative balance between viral spread and the immune response. Some circumstances, however, were found in infections with a noncytopathic virus in which vaccination caused disease; sensitive parameters included the genetic background of the host, the time or dose of infection, and the constituents of the vaccine. Thus, immunopathologic damage by T cells may be an unwanted consequence of vaccination with the new types of peptide or recombinant vaccines that are being investigated for the human immunodeficiency viruses and other pathogens.

    Full Text Available Vaccine informatics is an emerging research area that focuses on development and applications of bioinformatics methods that can be used to facilitate every aspect of the preclinical, clinical, and postlicensure vaccine enterprises. Many immunoinformatics algorithms and resources have been developed to predict T- and B-cell immune epitopes for epitope vaccine development and protective immunity analysis. Vaccine protein candidates are predictable in silico from genome sequences using reverse vaccinology. Systematic transcriptomics and proteomics gene expression analyses facilitate rational vaccine design and identification of gene responses that are correlates of protection in vivo. Mathematical simulations have been used to model host-pathogen interactions and improve vaccine production and vaccination protocols. Computational methods have also been used for development of immunization registries or immunization information systems, assessment of vaccine safety and efficacy, and immunization modeling. Computational literature mining and databases effectively process, mine, and store large amounts of vaccine literature and data. Vaccine Ontology (VO has been initiated to integrate various vaccine data and support automated reasoning.

  17. Vaccines for allergy.

    Linhart, Birgit; Valenta, Rudolf

    2012-06-01

    Vaccines aim to establish or strengthen immune responses but are also effective for the treatment of allergy. The latter is surprising because allergy represents a hyper-immune response based on immunoglobulin E production against harmless environmental antigens, i.e., allergens. Nevertheless, vaccination with allergens, termed allergen-specific immunotherapy is the only disease-modifying therapy of allergy with long-lasting effects. New forms of allergy diagnosis and allergy vaccines based on recombinant allergen-derivatives, peptides and allergen genes have emerged through molecular allergen characterization. The molecular allergy vaccines allow sophisticated targeting of the immune system and may eliminate side effects which so far have limited the use of traditional allergen extract-based vaccines. Successful clinical trials performed with the new vaccines indicate that broad allergy vaccination is on the horizon and may help to control the allergy pandemic.

    This review article outlines the key concepts in vaccine epidemiology, such as basic reproductive numbers, force of infection, vaccine efficacy and effectiveness, vaccine failure, herd immunity, herd effect, epidemiological shift, disease modeling, and describes the application of this knowledge both at program levels and in the practice by family physicians, epidemiologists, and pediatricians. A case has been made for increased knowledge and understanding of vaccine epidemiology among key stakeholders including policy makers, immunization program managers, public health experts, pediatricians, family physicians, and other experts/individuals involved in immunization service delivery. It has been argued that knowledge of vaccine epidemiology which is likely to benefit the society through contributions to the informed decision-making and improving vaccination coverage in the low and middle income countries (LMICs). The article ends with suggestions for the provision of systematic training and learning platforms in vaccine epidemiology to save millions of preventable deaths and improve health outcomes through life-course.

    2011-03-01

    The current tuberculosis (TB) vaccine, bacille Calmette-Guerin (BCG), is a live vaccine used worldwide, as it protects against severe forms of the disease, saving thousands of lives every year, but its efficacy against pulmonary forms of TB, responsible for transmission of the diseases, is variable. For more than 80 years now no new TB vaccines have been successfully developed. Over the last decade the effort of the scientific community has resulted in the design and construction of promising vaccine candidates. The goal is to develop a new generation of vaccines effective against respiratory forms of the disease. We will focus this review on new prophylactic vaccine candidates that aim to prevent TB diseases. Two are the main strategies used to improve the immunity conferred by the current BCG vaccine, by boosting it with new subunit vaccines, and a second strategy is focused on the construction of new more effective live vaccines, capable to replace the current BCG and to be used as prime vaccines. After rigorous preclinical studies in different animal models new TB vaccine candidates enter in clinical trials in humans. First, a small Phase I for safety followed by immunological evaluation in Phase II trials and finally evaluated in large population Phase III efficacy trials in endemic countries. At present BCG prime and boost with different subunit vaccine candidates are the more advanced assessed in Phase II. Two prime vaccines (based on recombinant BCG) have been successfully evaluated for safety in Phase I trials. A short number of live attenuated vaccines are in advance preclinical studies and the candidates ready to enter Phase I safety trials are produced under current good manufacturing practices.

  3. In the Eye of the Beholder? UN and the Use of Drones to Protect Civilians

    Directory of Open Access Journals (Sweden)

    John Karlsrud

    2013-06-01

    Full Text Available The debate on the UN’s possible use of drones for peacekeeping took a turn in 2013 when the Security Council granted the Department of Peacekeeping Operations (DPKO permission to contract surveillance drones for MONUSCO, its peacekeeping mission in the Democratic Republic of Congo (DRC. This article examines what drone capability may entail for UN peacekeeping missions. We find that surveillance drones can help missions acquire better information and improve the situational awareness of its troops, as well as inform decision-making by leadership, police, and civilian components of the mission. We see a significant potential in the use of surveillance drones to improve efforts to protect civilians, increase UN troops’ situational awareness, and improve access to vulnerable populations in high-risk theaters. The use of drones can dramatically improve information-gathering capacities in proximity to populations at risk, thereby strengthening the ability of peacekeepers to monitor and respond to human rights abuses as well as violations of international humanitarian law (IHL. Drones may also enable peacekeepers to maintain stealth surveillance of potential spoilers, including arms smugglers and embargo breakers. They could additionally improve UN forces’ own targeting practices, further contributing to the protection of civilians (PoC. Furthermore, we emphasize how drone capability significantly increases peacekeepers’ precautionary obligations under IHL in targeting situations: the availability of drones triggers the obligation to use them to gather information in order to avoid civilian casualties or other violations of IHL or international human rights law. There may soon come a shift among human rights groups, from being skeptical of the use of drones by UN peacekeepers to demanding that peacekeeping operations be equipped with surveillance drones for humanitarian and human rights reasons – shifting the current debate, which has

    Full Text Available Active immunization of children has been proven very effective in elimination of life threatening complications of many infectious diseases in developed countries. However, as vaccination-preventable infectious diseases and their complications have become rare, the interest focuses on immunization-related adverse reactions. Unfortunately, fear of vaccination-related adverse effects can led to decreased vaccination coverage and subsequent epidemics of infectious diseases. This review includes reports about possible side effects following vaccinations in children with neurological disorders and also published recommendations about vaccinating children with neurological disorders. From all international published data anyone can conclude that vaccines are safer than ever before, but the challenge remains to convey this message to society.

    Traveler's vaccination is one of the key strategies for the prevention of infectious diseases during international travel. The risk of acquiring an infectious disease is determined in each case by the characteristics of the traveler and the travel, so the pre-departure medical advice of the traveler must be individualized. The World Health Organization classifies travelerś vaccines into three groups. - Vaccines for routine use in national immunization programs: Haemophilus influenzae type b, hepatitis B, polio, measles-mumps-rubella, tetanus-diphtheria-whooping a cough, and chickenpox. - Vaccinations required by law in certain countries before to enter them: yellow fever, meningococcal disease and poliomyelitis. - Vaccines recommended depending on the circumstances: cholera, japanese encephalitis, tick-borne encephalitis, meningococcal disease, typhoid fever, influenza, hepatitis A, hepatitis B, rabies and BCG. This review is intended to introduce the reader to the field of international vaccination. PMID:26920587

    Full Text Available Since the Boko Haram uprising in 2009, the Nigerian government has employed various strategies as counter-terrorism measures to stem the atrocities of the group. These strategies include amnesty negotiations, implementation of emergency law in the northeast, increase in security spending to the deployment of military force. In the midst of these security measures, the civilian Joint Task Force (JTF emerged, first as a community effort, and later as a joint effort with the security forces to help fight Boko Haram. The civilian JTF has helped recover towns and villages from Boko Haram, rescued women in the northeast and helped identify Boko Haram members shielded by some local people. Although doubts have been expressed in some quatres that the civilian JTF could transform into ethnic militias, the Boko Haram security threat neutralized by the group indicates an untapped security potential in Nigerian communities. However, one approach that has yet to be pursued is community security option. Community security option is a model built around proactive citizen-driven communal response. This article explains the role of civilian JTF and how civilian JTF can be used to investigate terrorism in Nigeria. This article will contribute to the discourse on the imperative of African-inspired mechanisms to solving African security problems.

En 1796 Edward Jenner desarrolló la primera vacuna contra la viruela: gracias a la vacunación se ha conseguido la erradicación de esta mortal enfermedad sobre el planeta. En otras enfermedades como el tétanos neonatal, la poliomielitis o el sarampión las campañas de vacunación han conseguido una drástica disminución de la morbi-mortalidad. Actualmente, estos logros conseguidos por las vacunas han producido una falsa percepción de ausencia de riesgo, en algunos casos han descendido las coberturas de vacunación, y se ha producido un aumento del número de casos y brotes de algunas enfermedades como el sarampión. A esta situación han contribuido los mensajes de algunos grupos contrarios a la vacunación que han atribuido a las vacunas una serie de efectos adversos que en ningún caso han sido probados por la comunidad científica.Throughout the last centuries, the first signs of vaccination were linked to variolation procedures. In 1796, Edward Jenner developed the first vaccine for smallpox: the world eradication of this mortal disease was achieved due to the vaccination. In other diseases, such as neonatal tetanus, poliomyelitis or measles, immunization programmes have drastically decreased morbidity and mortality. Nowadays, these achievements of vaccination have caused a false perception of lack of risk, causing a decrease in immunization coverage in some cases. There has been a considerable increase on reported cases and outbreaks of some diseases such as measles. The messages of anti-vaccination movements have contributed to generate this situation by associating some adverse effects with vaccines, but there is no scientific evidence to support it.

    Full Text Available BACKGROUND: wars and its challenges have historically afflicted humanity. In Syria, severe injuries occurred due to firearms and explosives used in the war between government forces and civilians for a period of over 2 years. MATERIALS AND METHODS: the study included 364 cases, who were admitted to Mustafa Kemal University Hospital, Medicine School (Hatay, Turkey, and underwent surgery. Survivors and non-survivors were compared regarding injury site, injury type and number of transfusions given. The mortality rate found in this study was also compared to those reported in other civil wars. RESULTS: the mean age was 29 (3-68 years. Major sites of injury included extremities (56.0%, head (20.1%, abdomen (16.2%, vascular structures (4.4% and thorax (3.3%. Injury types included firearm injury (64.4%, blast injury (34.4% and miscellaneous injuries (1.2%. Survival rate was 89.6% while mortality rate was 10.4%. A significant difference was observed between mortality rates in this study and those reported for the Bosnia and Lebanon civil wars; and the difference became extremely prominent when compared to mortality rates reported for Vietnam and Afghanistan civil wars. CONCLUSION: among injuries related to war, the highest rate of mortality was observed in head-neck, abdomen and vascular injuries. We believe that the higher mortality rate in the Syrian Civil War, compared to the Bosnia, Vietnam, Lebanon and Afghanistan wars, is due to seeing civilians as a direct target during war.

    The aim of this study was to analyse the circumstances, the forensic assessment and the legal assessment of police shootings of civilians, according to the severity of the victim's injuries. Sixty-nine cases tried in Portuguese criminal courts were analysed. Of the 32 cases that resulted in death, 16 were on the public thoroughfare and 13 were in the victim's vehicle or in third-party vehicles. The majority of the lethal cases occurred when the region of the body hit was the thorax/abdomen. The firearm most frequently used was a semi-automatic 9 mm pistol. In cases resulting in death police officers involved were convicted whilst those involved in non-lethal cases were acquitted. The results of this study can be taken into account by Portuguese authorities for the implementation of policies that will allow the restriction of firearms use by police officers to situations of imminent danger of death or serious injury and that will make it possible to avoid shooting at fleeing civilians.

    2002-08-01

    Today's society places an extremely high price on the value of human life and injury. Whenever possible, police and paramilitary actions are always directed towards saving as many lives as possible, whether it is the officer, perpetrator, or innocent civilians. Recently, the advent of robotic systems has enable law enforcement agencies to perform many of the most dangerous aspects of their jobs from relative safety. This is especially true to bomb disposal units but it is also gaining acceptance in other areas. An area where small, remotely operated machines may prove effective is in local aerial surveillance. Currently, the only aerial surveillance assets generally available to law enforcement agencies are costly helicopters. Unfortunately, most of the recently developed unmanned air vehicles (UAVs) are directed towards military applications and have limited civilian use. Systems Planning and Analysis, Inc. (SPA) has conceived and performed a preliminary analysis of a low-cost, inflatable, lighter- than-air surveillance system that may be used in a number of military and law enforcement surveillance situations. The preliminary analysis includes the concept definition, a detailed trade study to determine the optimal configuration of the surveillance system, high-pressure inflation tests, and a control analysis. This paper will provide the details in these areas of the design and provide an insight into the feasibility of such a system.

    2013-06-01

    Post-traumatic headache (PTH) is the most frequent symptom after traumatic brain injury (TBI). We review the epidemiology and characterization of PTH in military and civilian settings. PTH appears to be more likely to develop following mild TBI (concussion) compared with moderate or severe TBI. PTH often clinically resembles primary headache disorders, usually migraine. For migraine-like PTH, individuals who had the most severe headache pain had the highest headache frequencies. Based on studies to date in both civilian and military settings, we recommend changes to the current definition of PTH. Anxiety disorders such as post-traumatic stress disorder (PTSD) are frequently associated with TBI, especially in military populations and in combat settings. PTSD can complicate treatment of PTH as a comorbid condition of post-concussion syndrome. PTH should not be treated as an isolated condition. Comorbid conditions such as PTSD and sleep disturbances also need to be treated. Double-blind placebo-controlled trials in PTH population are necessary to see whether similar phenotypes in the primary headache disorders and PTH will respond similarly to treatment. Until blinded treatment trials are completed, we suggest that, when possible, PTH be treated as one would treat the primary headache disorder(s) that the PTH most closely resembles.

    This report documents an analysis of the Total System Life Cycle Cost (TSLCC) for one concept for the Civilian Radioactive Waste Management System (CRWMS). This analysis is consistent with the design basis of the selected alternative, Enhanced Design Alternative II (EDA II), evaluated in the ''License Application Design Selection Report'' (CRWMS M and O 1999c). Two cost scenarios are presented within this document to address open policy questions relating to the implementation of the EDA II design from the License Applications Design Selection (LADS) study. Both cases represent the total system cost for the EDA II design described in the LADS Report, modified for emplacing all planned waste quantities in ''The Civilian Radioactive Waste Management System Requirements Document'', Rev. 05 (DOE 1999a). Case 1 assumes that closure and decommissioning activities can begin 50 years after the beginning of waste emplacement. Subsequent to the publication of the LADS Report (CRWMS M and O 1999c), discussions with the Nuclear Waste Technical Review Board (NWTRB) led to the consideration of keeping the repository open and ventilated for an additional 75 years. Case 2 represents the contingency of beginning closure and decommissioning activities 125 years after the beginning of waste emplacement, when it is expected that the temperature of the emplacement drift walls will remain below the boiling point of water

    This article examines the processes through which civilian fear was turned into a practicable investigative object in the inter-war period and the opening stages of the Second World War, and how it was invested with significance at the level of science and of public policy. Its focus is on a single historical actor, Solly Zuckerman, and on his early war work for the Ministry of Home Security-funded Extra Mural Unit based in Oxford's Department of Anatomy (OEMU). It examines the process by which Zuckerman forged a working relationship with fear in the 1930s, and how he translated this work to questions of home front anxiety in his role as an operational research officer. In doing so it demonstrates the persistent work applied to the problem: by highlighting it as an ongoing research project, and suggesting links between seemingly disparate research objects (e.g. the phenomenon of 'blast' exposure as physical and physiological trauma), the article aims to show how civilian 'nerve' emerged from within a highly specific analytical and operational matrix which itself had complex foundations.

    The aim of this study was to analyse the circumstances, the forensic assessment and the legal assessment of police shootings of civilians, according to the severity of the victim's injuries. Sixty-nine cases tried in Portuguese criminal courts were analysed. Of the 32 cases that resulted in death, 16 were on the public thoroughfare and 13 were in the victim's vehicle or in third-party vehicles. The majority of the lethal cases occurred when the region of the body hit was the thorax/abdomen. The firearm most frequently used was a semi-automatic 9 mm pistol. In cases resulting in death police officers involved were convicted whilst those involved in non-lethal cases were acquitted. The results of this study can be taken into account by Portuguese authorities for the implementation of policies that will allow the restriction of firearms use by police officers to situations of imminent danger of death or serious injury and that will make it possible to avoid shooting at fleeing civilians.

    Full Text Available Vaccinology was developed for the first time in 1796 when Jenner empirically implemented a vaccine against smallpox using animal-to-human cowpox inoculation. Since then, it has become a very complex science due to the merging of disciplines ranging from structural and functional, cellular and molecular biology and immunology to bioinformatics and nanobiotechnology, as well as systems biology and synthetic biology and engineering. In the frame of evidence-based medicine (EBM, evidence-based vaccinology emerged as an important sub-field: vaccinology has nowadays become more and more predictive and personalized. With the discovery that many patients with cancer develop antibodies against p53 (the so-called oncoantibodies, it was evident that oncoprotein are immunogenic and can be used for immunotherapeutics purposes. In this manuscript, we report Nucleic Acid Programmable Protein Arrays (NAPPA-based Quartz Crystal Microbalance (QCM measurement of p53 immunogenicity and kinetics, in the perspective of developing an effective p53 therapy. NAPPA-based QCM_D can be a useful platform for proving the immunogenicity of oncoprotein-based vaccines. Recently, the field of vaccinology has extended from vaccines for infectious diseases to vaccines not only preventive but also therapeutic for chronic-degenerative diseases such as cancer. Peptide-based immunotherapeutics has been proven to be quite effective for cancer treatment and NAPPA-based QCM_D has the promise of providing clinicians with quick, rapid and cheap measurement of oncoprotein kinetics and bindings with immune cells. Moreover, it can be a precious tool for implementing personalized and predictive vaccinology.

    The ongoing outbreak of Ebola virus disease in West Africa highlighted the lack of a licensed drug or vaccine to combat the disease and has renewed the urgency to develop a pipeline of Ebola vaccines. A number of different vaccine platforms are being developed by assessing preclinical efficacy in animal models and expediting clinical development. Over 15 different vaccines are in preclinical development and 8 vaccines are now in different stages of clinical evaluation. These vaccines include DNA vaccines, virus-like particles and viral vectors such as live replicating vesicular stomatitis virus (rVSV), human and chimpanzee adenovirus, and vaccinia virus. Recently, in preliminary results reported from the first phase III trial of an Ebola vaccine, the rVSV-vectored vaccine showed promising efficacy. This review charts this rapidly advancing area of research focusing on vaccines in clinical development and discusses the future opportunities and challenges faced in the licensure and deployment of Ebola vaccines.

    Overcoming preexisting immunity to vaccinia virus in the adult population is a key requirement for development of otherwise potent recombinant vaccinia vaccines. Based on our observation that s.c. immunization with vaccinia induces cellular and antibody immunity to vaccinia only in systemic lymphoid tissue and not in mucosal sites, we hypothesized that the mucosal immune system remains naive to vaccinia and therefore amenable to immunization with recombinant vaccinia vectors despite earlier vaccinia exposure. We show that mucosal immunization of vaccinia-immune BALB/c mice with recombinant vaccinia expressing HIV gp160 induced specific serum antibody and strong HIV-specific cytotoxic T lymphocyte responses. These responses occurred not only in mucosal but also in systemic lymphoid tissue, whereas systemic immunization was ineffective under these circumstances. In this context, intrarectal immunization was more effective than intranasal immunization. Boosting with a second dose of recombinant vaccinia was also more effective via the mucosal route. The systemic HIV-specific cytotoxic T lymphocyte response was enhanced by coadministration of IL-12 at the mucosal site. These results also demonstrate the independent compartmentalization of the mucosal versus systemic immune systems and the asymmetric trafficking of lymphocytes between them. This approach to circumvent previous vaccinia immunity may be useful for induction of protective immunity against infectious diseases and cancer in the sizable populations with preexisting immunity to vaccinia from smallpox vaccination.

    Vaccines have been used for over 200 years and are the most effective way of preventing the morbidity and mortality associated with infections. Like other drugs, vaccines can cause adverse events, but unlike conventional medicines, which are prescribed to people who are ill, vaccines are administered to healthy individuals, thus increasing the concern over adverse reactions. Most side effects attributed to vaccines are mild, acute and transient; however, rare reactions such as hypersensitivity, induction of infection, and autoimmunity do occur and can be severe and even fatal. The rarity and subacute presentation of post-vaccination autoimmune phenomena means that ascertaining causality between these events can be difficult. Moreover, the latency period between vaccination and autoimmunity ranges from days to years. In this article, on the basis of published evidence and our own experience, we discuss the various aspects of the causal and temporal interactions between vaccines and autoimmune phenomena, as well as the possible mechanisms by which different components of vaccines might induce autoimmunity.

    Vaccines have eradicated or controlled many infectious diseases, saving each year millions of lives and quality of life of many other millions of people. In spite of the success of vaccines over the last two centuries, parents (and also some health care workers) gloss over the devastating consequences of diseases, which are now avoided thanks to vaccines, and direct their attention to possible negative effects of immunization. Three immunological objections are raised: vaccines cause antigenic overload, natural immunity is safer and better than vaccine-induced immunity, and vaccines induce autoimmunity. The last point is examined in this review. Theoretically, vaccines could trigger autoimmunity by means of cytokine production, anti-idiotypic network, expression of human histocompatibility leukocyte antigens, modification of surface antigens and induction of novel antigens, molecular mimicry, bystander activation, epitope spreading, and polyclonal activation of B cells. There is strong evidence that none of these mechanisms is really effective in causing autoimmune diseases. Vaccines are not a source of autoimmune diseases. By contrast, absolute evidence exists that infectious agents can trigger autoimmune mechanisms and that they do cause autoimmune diseases.

    This report describes a groundbreaking military-civilian collaboration that benefits from an Army and Department of Defense (DoD) big data business intelligence platform called the Person-Event Data Environment (PDE). The PDE is a consolidated data repository that contains unclassified but sensitive manpower, training, financial, health, and medical records covering U.S. Army personnel (Active Duty, Reserve, and National Guard), civilian contractors, and military dependents. These unique data assets provide a veridical timeline capturing each soldier's military experience from entry to separation from the armed forces. The PDE was designed to afford unprecedented cost-efficiencies by bringing researchers and military scientists to a single computerized repository rather than porting vast data resources to individual laboratories. With funding from the Robert Wood Johnson Foundation, researchers from the University of Pennsylvania Positive Psychology Center joined forces with the U.S. Army Research Facilitation Laboratory, forming the scientific backbone of the military-civilian collaboration. This unparalleled opportunity was necessitated by a growing need to learn more about relations between psychological and health assets and health outcomes, including healthcare utilization and costs-issues of major importance for both military and civilian population health. The PDE represents more than 100 times the population size and many times the number of linked variables covered by the nation's leading sources of population health data (e.g., the National Health and Nutrition Examination Survey). Following extensive Army vetting procedures, civilian researchers can mine the PDE's trove of information using a suite of statistical packages made available in a Citrix Virtual Desktop. A SharePoint collaboration and governance management environment ensures user compliance with federal and DoD regulations concerning human subjects' protections and also provides a secure

    Invasive infections caused by Neisseria meningitidis are a serious public health problem worldwide and have a heavy economic impact. The incidence of invasive disease due to Neisseria meningitidis is highly variable according to geographical area and serogroup distribution. Since the introduction of vaccination programs with conjugated vaccine C in children and adolescents, most cases of invasive meningococcal disease in developed countries have been caused by meningococcus B. It is important to underline that invasive meningococcal disease will not be controlled until safe and effective vaccines for meningococcal B are available and widely used. The aims of this article are to describe the most recent developments in meningococcal B vaccines and to discuss how these vaccines can contribute to containing meningococcal disease.

    Background: In the context of the Canadian mission in Afghanistan, substantial media attention has been placed on mental health and lack of access to treatment among Canadian Forces personnel. We compared trends in the prevalence of suicidal behaviour and the use of mental health services between Canadian military personnel and the general population from 2002 to 2012/13. Methods: We obtained data for respondents aged 18–60 years who participated in 4 nationally representative surveys by Statistics Canada designed to permit comparisons between populations and trends over time. Surveys of the general population were conducted in 2002 (n = 25 643) and 2012 (n = 15 981); those of military personnel were conducted in 2002 (n = 5153) and 2013 (n = 6700). We assessed the lifetime and past-year prevalence of suicidal ideation, plans and attempts, as well as use of mental health services. Results: In 2012/13, but not in 2002, military personnel had significantly higher odds of both lifetime and past-year suicidal ideation than the civilian population (lifetime: adjusted odds ratio [OR] 1.32, 95% confidence interval [CI] 1.17–1.50; past year: adjusted OR 1.34, 95% CI 1.09–1.66). The same was true for suicidal plans (lifetime: adjusted OR 1.64, 95% CI 1.35–1.99; past year: adjusted OR 1.66, 95% CI 1.18–2.33). Among respondents who reported past-year suicidal ideation, those in the military had a significantly higher past-year utilization rate of mental health services than those in the civilian population in both 2002 (adjusted OR 2.02, 95% CI 1.31–3.13) and 2012/13 (adjusted OR 3.14, 95% CI 1.86–5.28). Interpretation: Canadian Forces personnel had a higher prevalence of suicidal ideation and plans in 2012/13 and a higher use of mental health services in 2002 and 2012/13 than the civilian population.

  20. Contribution of civilian industry to the management of military fissile materials

    International Nuclear Information System (INIS)

    The situation about using of highly enriched uranium (HEU) and weapon grade plutonium (WgPu) for nuclear fuel preparation in U.S.A. and Russian Federation is reviewed. A few remarks were concluded: (1) We stand at the onset of a process that will be lengthy and which is unlikely to stop with the elimination of the 700 t of HEU and 2 x 34.5 t of WgPu concerned so far. If the announced negotiation of the third START treaty concludes favorably, additional tonnages will have to be recycled, particularly on the Russian side whose estimated inventory is larger. (2) The time scales necessitated by the management of these materials should be no surprise. On the one hand, the aim is to reduce an arsenal built up during 45 years of a Cold War. And this return to civilian life of materials of military origin must be achieved in conditions of safety and bilateral or international safeguards (IAEA), which obviously did not constitute the primary concern of the powers who produced them. Besides, insofar as it enlists the services of civilian industry, this return must be carried out with due respect for the equilibrium of markets that are severely mauled today, in other words, in an orderly and progressive manner. (3) Finally, it is important to recognize that without the contribution of the nuclear power industry, the elimination of military fissile materials would raise problems at another scale and would inevitably lead to regrettable waste. It is to be hoped that this will jog the minds of those who urge a rapid end to nuclear energy, when all the evidence demonstrates that the best way to eliminate surplus weapon grade materials is to recycle them in a reactor, in other words, to destroy them or to denature them while generating electricity. (4) The civilian nuclear industry is happy to contribute concretely and significantly to the solution of a problem of surplus nuclear weaponry, while at the same time utilizing technologies successfully developed for power generation

  1. Exposure to the atmospheric ionizing radiation environment: studies on Icelandic and Italian civilian aviation flight personnel

    de Angelis, G.; Caldora, M.; Santaquilani, M.; Scipione, R.; Verdecchia, A.; Rafnsson, V.; Hrafnkelsson, J.; Sulem, P.; Gudjonsdottir, A. J.

    The largest source of data on human exposure to low dose rate radiation may be airline flight personnel, if enrolled for studies on health effects induced by the cosmic-ray-generated atmospheric ionizing radiation, whose total dose, increasing over the years, may cause delayed radiation-induced health effects, with the high-LET and highly ionizing neutron component typical of atmospheric radiation. With regards to this, the Italian civilian airline flight personnel have been studied by analyzing the atmospheric ionizing radiation exposure and associated effects. The study population includes all Italian civilian airline flight personnel, both cockpit and cabin crewmembers, whose work history records and actual flights (route, aircraft type, and date for each individual flight for each person where possible) were available. The dose calculations were performed along specific flight legs, taking into account the actual flight profiles for all different routes and the variations with time of solar and geomagnetic parameters, in order to take into account the whole atmospheric neutron spectrum. Dose values for each flight are applied to the flight history of study participants in order to estimate the individual annual and lifetime occupational radiation dose. Following the same protocols for both cohorts in terms of dose evaluation, a comparative study has been performed between the radiation exposure patterns of the Icelandic and the Italian civilian aviation flight personnel. These two populations represent two extremes within the group of worldwide airline personnel. The Icelandic crewmembers, like only in the world their Canadian colleagues, always fly over or very close to the geomagnetic pole, and are this way exposed to high doses within each flight leg, whereas the Italian crewmembers, apart from transatlantic flights, are always flying close to the geomagnetic equator or anyhow quite far from the geomagnetic pole, receiving a small dose rates for each flight

  2. Vaccines for canine leishmaniasis

    2012-04-01

    Full Text Available Leishmaniasis is the third most important vector-borne disease worldwide. Visceral leishmaniasis (VL is a severe and frequently lethal protozoan disease of increasing incidence and severity due to infected human and dog migration, new geographical distribution of the insect due to global-warming, co-infection with immunosuppressive diseases and poverty. The disease is an anthroponosis in India and Central Africa and a canid zoonosis (ZVL in the Americas, the Middle East, Central Asia, China and the Mediterranean. The ZVL epidemic has been controlled by one or more measures including the culling of infected dogs, treatment of human cases and insecticidal treatment of homes and dogs. However, the use of vaccines is considered the most cost-effective control tool for human and canine disease. Since the severity of the disease is related to the generation of T-cell immunosuppression, effective vaccines should be capable of sustaining or enhancing the T-cell immunity. In this review we summarize the clinical and parasitological characteristics of ZVL with special focus on the cellular and humoral canine immune response and review state-of-the-art vaccine development against human and canine visceral leishmaniasis. Experimental vaccination against leishmaniasis has evolved from the practice of leishmanization with living parasites to vaccination with crude lysates, native parasite extracts to recombinant and DNA vaccination. Although more than 30 defined vaccines have been studied in laboratory models no human formulation has been licensed so far; however three second-generation canine vaccines have already been registered. As expected for a zoonotic disease, the recent preventive vaccination of dogs in Brazil has led to a reduction in the incidence of canine and human disease. The recent identification of several Leishmania proteins with T-cell epitopes anticipates development of a multiprotein vaccine that will be capable of protecting both humans

    2004-04-01

    Lassa fever remains a serious challenge to public health in West Africa threatening both local residents in rural areas and those who serve them, particularly medical care providers. Given the ecology of the rodent host and conditions in the endemic area, a vaccine is mandatory for control. The challenge is to overcome the scientific, political and economic obstacles to producing a human use vaccine candidate. There are some scientific issues to resolve. It is known that the G-protein confers protection but we do not know its duration. If the N-protein is also included there may be a better duration of protection but it is unclear whether the N-protein as a vaccine may possibly enhance the infection. The original vaccinia vector must be replaced by new vectors, chimeras or by delivering DNA in some format. A live vaccine is attractive because it can confer protection in a single shot. A killed vaccine is more stable, particularly for distribution in the tropics but usually requires repeated shots. For practical reasons a live vaccine format should probably be pursued, which could then be combined with a yellow fever vaccine, using the same cold chains, since this disease occupies the same endemic areas in West Africa. Lassa vaccine initiatives have suffered from a lack of funding in the past but bioterrorism has brought new resources to Lassa virus science. Adequate funding and applications of new vaccine technologies give hope that we may soon see a vaccine in clinical trials. However, the difficulty of conducting trials in endemic areas and lack of political stability remain serious problems. PMID:15056044

    The Vaccine Safety Datalink (VSD) is a collaborative project between the Centers for Disease Control and Prevention (CDC) and 9 health care organizations. Established in 1990, VSD is a vital resource informing policy makers and the public about the safety of vaccines used in the United States. Large linked databases are used to identify and evaluate adverse events in over 9 million individuals annually. VSD generates rapid, important safety assessments for both routine vaccinations and emergency vaccination campaigns. VSD monitors safety of seasonal influenza vaccines in near-real time, and provided essential information on the safety of influenza A (H1N1) 2009 monovalent vaccine during the recent pandemic. VSD investigators have published important studies demonstrating that childhood vaccines are not associated with autism or other developmental disabilities. VSD prioritizes evaluation of new vaccines; searches for possible unusual health events after vaccination; monitors vaccine safety in pregnant women; and has pioneered development of biostatistical research methods.

  8. Civilian and military uses of depleted uranium. Environmental and health problems

    International Nuclear Information System (INIS)

    Depleted uranium is a by-product of the process of enrichment of natural uranium and is classified as a toxic and radioactive waste; it has a very high density (approximately 19 g cm-3), a remarkable ductility and a cost low enough to be attractive for some particular technical applications. Civilian uses are essentially related to its high density, but the prevailing use is however military (production of projectiles). From the radioactive point of view, the exposure to depleted uranium can result from both external irradiation as well as internal contamination. The associated risks are however mainly of chemical-toxicological kind and the target organ is the kidney. In the present note the recent military uses and the possible effects of its environmental diffusion are discussed

    Head injury commonly presents in association with torso or limb injuries, especially in blunt trauma mechanisms. Stopping life-threatening thoraco-abdominal hemorrhage and preventing secondary brain injury are time critical priorities. Although simultaneous operative management by multiple teams has been common practice in the recent wars in Iraq and Afghanistan, simultaneous surgery is rare in most civilian settings. Nevertheless, situations arise whereby simultaneous craniotomy and chest or abdominal surgery is necessary to prevent mortality or reduce severe morbidity. We discuss two recent cases at our level one trauma centre, the challenges that surgeons and the operating room staff face and propose that with appropriate planning this surgical capability can be integrated into the systems of contemporary advanced trauma units.

    The annual meeting of the Infectious Disease Society of America (IDSA) ; which brought together nearly 5000 participants from over 80 countries in Vancouver, Canada, October 21 to 24, 2010 ; provided a review of the influenza (H1N1) 2009 pandemic, evaluated vaccination programmes and presented new vaccines under development. With 12,500 deaths in the United States in 2009-2010, the influenza (H1N1) 2009 pandemic was actually less deadly than the seasonal flu. But it essentially hit the young, and the toll calculated in years of life lost is high. The monovalent vaccines, whether live attenuated or inactivated with or without adjuvants, were well tolerated in toddlers, children, adults and pregnant women. In order to protect infants against pertussis, family members are urged to get their booster shots. The introduction of the 13-valent Pneumococcal conjugated vaccine in the beginning of 2010 may solve - but for how long ? - the problem of serotype replacement, responsible for the re-increasing incidence of invasive Pneumococcal infections observed in countries that had introduced the 7-valent vaccine. The efficacy of a rotavirus vaccine has been confirmed, with a reduction in hospitalization in the United States and a reduction in gastroenteritis-related deaths in Mexico. In the United States, vaccination of pre-adolescents against human papillomavirus (HPV) has not resulted in any specific undesirable effects. Routine vaccination against chicken pox, recommended since 1995, has not had an impact on the evolution of the incidence of shingles. Vaccination against shingles, recommended in the United States for subjects 60 years and over, shows an effectiveness of 55 %, according to a cohort study (Kaiser Permanente, Southern California). Although some propose the development of personalized vaccines according to individual genetic characteristics, the priority remains with increasing vaccine coverage, not only in infants but also in adults and the elderly.

  14. Rethinking gender-based violence during war: is violence against civilian men a problem worth addressing?

    Linos, Natalia

    2009-04-01

    Gender-based violence during conflict and post-conflict situations has received increased attention in research and in the work of development agencies. Viewed primarily as a form of violence against women, this commentary questions whether male civilians have also been victims of gender-based violence during conflict, invisible due to stereotypes surrounding masculinity and a culturally permissive approach towards violence perpetrated against men, especially at times of war. The experience of civilian males of violence, including sexual violence, during the war in Bosnia and Herzegovina and other contemporary wars, suggests that the discourse on gender-based violence and public health research should begin exploring the specific needs of men. Drawing on Nancy Krieger's (Krieger, N. (2003). Genders, sexes, and health: what are the connections-and why does it matter? International Journal of Epidemiology, 32, 652-657) analysis on the differential role of 'sex' and 'gender' on a given exposure-outcome association, this commentary suggests that the impact of gender-based violence on health during conflict may be different for men and women and may require distinct therapeutic approaches. Given that perpetrators are often male, an extra level of stigma is added when heterosexual men are sexually violated, which may lead to underreporting and reduced health-service seeking behavior. Further public health research is needed to guide the work of humanitarian agencies working with survivors of gender-based violence in conflict and post-conflict settings to ensure equal access to appropriate health services for men and women.

  15. Almonte's great train disaster: Shaping nurses' roles and the civilian use of blood transfusion.

    Science.gov (United States)

    Toman, Cynthia

    2004-01-01

    Blood transfusion was initially a small-scale, labour-intensive therapy administered by physicians. Through the first decades of the 20th century, transfusion comprised a "last resort" measure used and tested primarily in the context of war. Media accounts of the Almonte train disaster on the night of 27 December 1942 linked survival to the newly established blood bank located 42 km east in Ottawa, Ontario. This event did not constitute a "first time" occurrence or a "great discovery" in the history of blood. But it did illustrate in a very visible and public manner that blood transfusion technology was now readily available for use in general hospitals and civilian populations. Canada had an infrastructure for the collection, processing, storage, and transportation of blood products, and for the recruitment of blood donors by the mid-1940s. As the need for blood declined toward the end of World War II, transfusion became a technology in need of application. The extension of transfusion to civilian populations, however, would require a ready source of labour-increased numbers of health care workers who were available continuously with the necessary knowledge and skills to assume the responsibility. Nurses were well situated for this technological role by a convergence of scientific, economic, labour, gender, professional, and educational influences that both facilitated and constrained blood transfusion as a nursing competency. This paper examines how the expanded use of one medical technology shaped related roles for nurses. Transfusion ultimately influenced nurses' work and the composition of the workforce as the first medical act "delegated" to nurses in Ontario (1947), setting a precedent for the delegation of further technologies over the next four decades.

    Full Text Available DNA, the essential part of the life is making way in to new vaccine technology. Plasmid vectors from the bacteria have revolutionized the world of vaccine design by its new technology – DNA vaccines. Small portion of the nucleotides from the pathogen held under the control of promoter in a plasmid vector can be used as a vaccine. DNA vaccines alleviate the odds of the other vaccines by having good hold on both the faces of the immunity. The key to the success of DNA vaccine lies in the route of administration of the vaccine which can be done in many ways. Prime boost strategy is an approach used to boost the action of DNA vaccine. To date there are only four DNA vaccine available in the market. [Vet World 2013; 6(4.000: 228-232

    Vaccinations are the most successful and cost-effective measures for prevention of infections. Important pathogens of respiratory tract infections (e.g. influenza viruses and pneumococci) can be effectively treated by vaccinations. The seasonal trivalent and recently now quadrivalent influenza vaccines include antigens from influenza A and B type viruses, which have to be modified annually oriented to the circulating strains. The effective protection by influenza vaccination varies considerably (too short protection time, mismatch); therefore, administration late in the year is the best approach (November/December). Two pneumococcal vaccines are recommended for adults: the over 30-year-old 23-valent polysaccharide vaccine (PPV23) and the 4-year-old 13-valent conjugate vaccine (PCV13). The immunological and clinical efficacy of PPV23 is controversially discussed; however, a moderate reduction of invasive pneumococcal infections is widely accepted. The PCV13 stimulates a T-cell response and has currently demonstrated its clinical efficacy in an impressive study (CAPiTA). The problem of PCV13 is the relatively limited coverage of only 47% of the currently circulating invasive pneumococcal serotypes. PMID:26330051

    Full Text Available In periods of seasonal influenza, during pandemic flu in the past and from recent experience that we have the emergence of influenza A (H1N1, pregnant compared with non-pregnant women are at increased risk to get sick and to develop serious complications up to mortality. Purpose: This paper examines the risks that arise for pregnant from contamination with the flu virus and the safety of influenza vaccination in pregnancy. Method: The method involves searching review and research studies in Pubmed data base mainly of the 2000 until 2009 and the words were used is pregnancy, flu vaccination, complications of the flu vaccination at the period of pregnancy. Results: Morbidity during periods of seasonal influenza in pregnant women is increased, while in times of pandemic are recorded fatalities. Based on this, specific recommendations have been made for a flu vaccination in pregnant women, both from the CDC, the American College of Obstetricians and Gynecologists in the U.S. and other official bodies like the World Health Organization, according to that the constitution of influenza vaccine in the pregnancy is necessary, given that the probability of morbidity in this period is increased at 10%. Conclusions: The studies so far to influenza vaccination in pregnancy, do not record serious complications for pregnant women and infants. However more research needs to be done on the safety of influenza vaccination in pregnancy.

    Malaria exacts a toll of disease to people in the Tropics that seems incomprehensible to those only familiar with medicine and human health in the developed world. The methods of molecular biology, immunology, and cell biology are now being used to develop an antimalarial vaccine. The Plasmodium parasites that cause malaria have many stages in their life cycle. Each stage is antigenically distinct and potentially could be interrupted by different vaccines. However, achieving complete protection by vaccination may require a better understanding of the complexities of B- and T-cell priming in natural infections and the development of an appropriate adjuvant for use in humans.

    2015-01-01

    Hepatitis B virus is a worldwide leading cause of acute and chronic liver disease including cirrhosis and hepatocellular carcinoma. Effective vaccines have been available since the early '80s and vaccination has proved highly successful in reducing the disease burden, the development of the carrier state and the HB-related morbidity and mortality in the countries where vaccination has been implemented.   Neutralizing (protective) antibodies (anti-HBs) induced by vaccination are targeted largely towards the amino acid hydrophilic region, referred to as the common a determinant which is present on the outer protein coat or surface antigen (HBsAg), spanning amino acids 124-149. This provides protection against all HBV genotypes (from A to H) and is responsible for the broad immunity afforded by hepatitis B vaccination. Thus, alterations of residues within this region of the surface antigen may determine conformational changes that can allow replication of the mutated HBV in vaccinated people. An important mutation in the surface antigen region was identified in Italy some 25 years ago in infants born to HBsAg carrier mothers who developed breakthrough infections despite having received HBIG and vaccine at birth. This virus had a point mutation from guanosine to adenosine at nucleotide position 587, resulting in aa substitution from glycine (G) to arginine (R) at position 145 in the a determinant. Since the G145R substitution alters the projecting loop (aa 139-147) of the a determinant, the neutralizing antibodies induced by vaccination are no longer able to recognize the mutated epitope. Beside G145R, other S-gene mutations potentially able to evade neutralizing anti-HBs and infect vaccinated people have been described worldwide. In addition, the emergence of Pol mutants associated with resistance to treatment with nucleos(t)ide analogues can select viruses with crucial changes in the overlapping S-gene, potentially able to alter the S protein immunoreactivity. Thus

    2012-01-01

    Over the past two decades, DNA vaccination has been developed as a method for the induction of immune responses. However, in spite of high expectations based on their efficacy in preclinical models, immunogenicity of first generation DNA vaccines in clinical trials was shown to be poor, and no DNA vaccines have yet been licensed for human use. In recent years significant progress has been made in the development of second generation DNA vaccines and DNA vaccine delivery methods. Here we review the key characteristics of DNA vaccines as compared to other vaccine platforms, and recent insights into the prerequisites for induction of immune responses by DNA vaccines will be discussed. We illustrate the development of second generation DNA vaccines with the description of DNA tattooing as a novel DNA delivery method. This technique has shown great promise both in a small animal model and in non-human primates and is currently under clinical evaluation.

    2007-01-01

    Full Text Available Abstract. The review article considers different variants of measles vaccine that may be classified into two groups, i.e., vaccines that do not contain viable measles virus, and attenuated measles vaccines which could be employed in unusual manner.The first group includes DNA-vaccines, recombinant vaccine strains encoding synthesis of measles hemagglutinin and fusion protein, as well as peptide vaccines containing molecular fragments of these proteins. The mentioned variants of vaccines were effective in animal experiments, but they have not been tested in humans. The second group includes live attenuated mucosal measles vaccins applied in combination with immunomodulator(s, as aerosol and intranasally. Efficiency of these vaccines was tested and confirmed by immunization of children and adults. Mucosal measles vaccine induces local production of IgA measles antibodies, along with induced synthesis of circulating IgM and IgG antibodies against measles. The latter experimental variant could be a live attenuated measles vaccine containing some immunity-modulating agent. Elaboration of these variant was based on the known data about transient immunosuppressive activity of measles vaccine. An appropriate experimental variant represents a mixture of attenuated measles vaccine and synthetic immunomodulating agent (MP-2 peptide which protects T-lymphocytes from inhibitory effect of the measles virus. In present revue, some data are presented concerning the mechanisms of immunogenic activity and adverse effects of measles vaccines.

  15. Beacon of Hope? Lessons Learned from Efforts to Reduce Civilian Deaths from Police Shootings in an Australian State.

    2016-04-01

    In the 1990s, the police service in Victoria, Australia, faced a crisis of community confidence due to a spate of civilian deaths from police shootings. In that decade, twice as many civilians died at the hands of the police in Victoria than in every other Australian state combined. Most of those killed were mentally ill and affected by drugs and alcohol, and were rarely a serious threat except to themselves. The problem was also almost entirely an urban phenomenon. Shootings in rural communities, where mentally ill people were more likely to be personally known to local police, were (and remain) almost unknown. The large number of fatalities was recognised as a serious threat to public confidence, and Victoria Police introduced a ground-breaking training programme, Operation Beacon. Operating procedures and weapons training were fundamentally changed, to focus on de-escalation of conflict and avoiding or minimising police use of force. In the short term, Operation Beacon was successful. Shooting incidents were dramatically reduced. However, during the first decade of the new century, the number of civilians being killed again increased. This article examines Operation Beacon, both as a successful model for reducing civilian deaths at the hand of police and as a cautionary tale for police reform. We argue that the lessons of Operation Beacon have been gradually forgotten and that old habits and attitudes resurfaced. Fatal shootings of mentally ill civilians can be prevented, but if success is to be other than temporary, the Beacon philosophy must be continually reemphasised by police management. PMID:26666251

    Because of high infectivity and significant disease burden, typhoid fever constitutes a major global health problem. Implementation of adequate food handling practices and establishment of safe water supplies are the cornerstone for the development of an effective prevention program. However, vaccination against typhoid fever remains an essential tool for the effective management of this disease. Currently, there are two well tolerated and effective licensed vaccines. One is based on defined subunit virulence (Vi) polysaccharide antigen and can be administered either intramuscularly or subcutaneously and the other is based on the use of live attenuated bacteria for oral administration. The advantages and disadvantages of the various approaches taken in the development of a vaccine against typhoid fever are discussed, along with the potential for future vaccine candidates.

    Currently licensed pneumococcal vaccines are based on the generation of antibodies to the pneumococcal polysaccharide, of which there are more than 90 different types. While these vaccines are highly effective against the serotypes included, their high cost and limited serotype coverage limits their usefulness worldwide, particularly in low resources areas. Thus alternative or adjunctive options are being actively pursued. This review will present these various approaches, including variation...

    Background: Rotaviruses remain the major cause of childhood diarrheal disease worldwide and of diarrheal deaths of infants and children in developing countries. The huge burden of childhood rotavirus-related diarrhea in the world continues to drive the remarkable pace of vaccine development. Data sources: Research articles were searched using terms "rotavirus" and "rotavirus vaccine" in MEDLINE and PubMed. Articles not published in the English language, articles without abstracts, and opinion articles were excluded from the review. After preliminary screening, all articles were reviewed and synthesized to provide an overview of current vaccines and vaccination programs. Results: In this review of the global rotavirus vaccines and vaccination programs, the principles of rotavirus vaccine development and the efficacy of the currently licensed vaccines from both developed and developing countries were summarized. Conclusions: Rotavirus is a common cause of diarrhea in children in both developed and developing countries. Rotavirus vaccination is a cost-effective measure to prevent rotavirus diarrhea.

    Traditionally, the design of new vaccines directed against Mycobacterium tuberculosis, the most successful bacterial pathogen on the planet, has focused on prophylactic candidates that would be given to individuals while they are still young. It is becoming more apparent, however, that there are several types of vaccine candidates now under development that could be used under various conditions. Thus, in addition to prophylactic vaccines, such as recombinant Mycobacterium bovis BCG or BCG-boosting vaccines, other applications include vaccines that could prevent infection, vaccines that could be given in emergency situations as postexposure vaccines, vaccines that could be used to facilitate chemotherapy, and vaccines that could be used to reduce or prevent relapse and reactivation disease. These approaches are discussed here, including the type of immunity we are trying to specifically target, as well as the limitations of these approaches.

  10. HPV vaccines: a controversial issue?

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Controversy still exists over whether the benefits of the available HPV vaccines outweigh the risks and this has suppressed uptake of the HPV vaccines in comparison to other vaccines. Concerns about HPV vaccine safety have led some physicians, healthcare officials and parents to withhold the recommended vaccination from the target population. The most common reason for not administering the prophylactic HPV vaccines are concerns over adverse effects. The aim of this review is the assessment of peer-reviewed scientific data related to measurable outcomes from the use of HPV vaccines throughout the world with focused attention on the potential adverse effects. We found that the majority of studies continue to suggest a positive risk-benefit from vaccination against HPV, with minimal documented adverse effects, which is consistent with other vaccines. However, much of the published scientific data regarding the safety of HPV vaccines appears to originate from within the financially competitive HPV vaccine market. We advocate a more independent monitoring system for vaccine immunogenicity and adverse effects to address potential conflicts of interest with regular systematic literature reviews by qualified individuals to vigilantly assess and communicate adverse effects associated with HPV vaccination. Finally, our evaluation suggests that an expanded use of HPV vaccine into more diverse populations, particularly those living in low-resource settings, would provide numerous health and social benefits.

  12. DNA vaccines against influenza.

    Genetic vaccine technology has been considerably developed within the last two decades. This cost effective and promising strategy can be applied for therapy of cancers and for curing allergy, chronic and infectious diseases, such as a seasonal and pandemic influenza. Despite numerous advantages, several limitations of this technology reduce its performance and can retard its commercial exploitation in humans and its veterinary applications. Inefficient delivery of the DNA vaccine into cells of immunized individuals results in low intracellular supply of suitable expression cassettes encoding an antigen, in its low expression level and, in turn, in reduced immune responses against the antigen. Improvement of DNA delivery into the host cells might significantly increase effectiveness of the DNA vaccine. A vast array of innovative methods and various experimental strategies have been applied in order to enhance the effectiveness of DNA vaccines. They include various strategies improving DNA delivery as well as expression and immunogenic potential of the proteins encoded by the DNA vaccines. Researchers focusing on DNA vaccines against influenza have applied many of these strategies. Recent examples of the most successful modern approaches are discussed in this review.

  13. Immunology of BVDV vaccines.

    Providing acquired immune protection against infection with bovine viral diarrhea viruses (BVDV) is challenging due to the heterogeneity that exists among BVDV strains and the ability of the virus to infect the fetus and establish persistent infections. Both modified live and killed vaccines have been shown to be efficacious under controlled conditions. Both humoral and cellular immune responses are protective. Following natural infection or vaccination with a modified live vaccine, the majority of the B cell response (as measured by serum antibodies) is directed against the viral proteins E2 and NS2/3, with minor responses against the Erns and E1 proteins. Vaccination with killed vaccines results in serum antibodies directed mainly at the E2 protein. It appears that the major neutralizing epitopes are conformational and are located within the N-terminal half of the E2 protein. While it is thought that the E2 and NS2/3 proteins induce protective T cell responses, these epitopes have not been mapped. Prevention of fetal infections requires T and B cell response levels that approach sterilizing immunity. The heterogeneity that exists among circulating BVDV strains, works against establishing such immunity. Vaccination, while not 100% effective in every individual animal, is effective at the herd level. PMID:22883306

    French military personnel are subject to a compulsory vaccination schedule. The aim of this study was to describe vaccine adverse events (VAE) reported from 2002 to 2010 in armed forces. VAE are routinely surveyed by the military Centre for epidemiology and public health. For each case, military practitioners fill a notification form, providing patient characteristics, clinical information and vaccines administered. For this study, VAE following influenza A(H1N1)pdm09 vaccination were excluded. Among the 473 cases retained, 442 (93%) corresponded to non-severe VAE,including local, regional and systemic events, while 31 corresponded to severe VAE, with two leading to significant disability. The global VAE reporting rate (RR) was 14.0 per 100,000 injections. While stationary from 2002 to 2008, the RR increased from 2009. The most important observations were a marked increase of VAE attributed to Bacillus Calmette-Guérin (BCG) vaccine from 2005 to 2008, a high RR observed with the inactivated diphtheria-tetanus (toxoids)-poliovirus vaccine combined with acellular pertussis vaccine (dTap-IPV) from 2008 and an increase in RR for seasonal influenza vaccine VAE in 2009. Our RR for severe VAE (1.1 VAEper 100,000) appears comparable with rates observed among United States civilians and military personnel. The increase observed from 2009 could be partly explained by the influenza A(H1N1)pdm09 pandemic which increased practitioner awareness towards VAE. In conclusion, the tolerance of the vaccines used in French armed forces appears acceptable.

    Background Since the 2008 inception of universal childhood influenza vaccination, national rates have risen more dramatically among younger children than older children and reported rates across racial/ethnic groups are inconsistent. Interventions may be needed to address age and racial disparities to achieve the recommended childhood influenza vaccination target of 70%. Purpose To evaluate an intervention to increase childhood influenza vaccination across age and racial groups. Methods In 2011–2012, 20 primary care practices treating children were randomly assigned to Intervention and Control arms of a cluster randomized controlled trial to increase childhood influenza vaccination uptake using a toolkit and other strategies including early delivery of donated vaccine, in-service staff meetings, and publicity. Results The average vaccination differences from pre-intervention to the intervention year were significantly larger in the Intervention arm (n=10 practices) than the Control arm (n=10 practices), for children aged 2–8 years (10.2 percentage points (pct pts) Intervention vs 3.6 pct pts Control) and 9–18 years (11.1 pct pts Intervention vs 4.3 pct pts Control, p<0.05), for non-white children (16.7 pct pts Intervention vs 4.6 pct pts Control, p<0.001), and overall (9.9 pct pts Intervention vs 4.2 pct pts Control, p<0.01). In multi-level modeling that accounted for person- and practice-level variables and the interactions among age, race and intervention, the likelihood of vaccination increased with younger age group (6–23 months), white race, commercial insurance, the practice’s pre-intervention vaccination rate, and being in the Intervention arm. Estimates of the interaction terms indicated that the intervention increased the likelihood of vaccination for non-white children in all age groups and white children aged 9–18 years. Conclusions A multi-strategy intervention that includes a practice improvement toolkit can significantly improve influenza
