    Smallpox vaccination: an early start of modern medicine in America.
    J Community Hosp Intern Med Perspect 2017 Jan 31;7(1):61-63. Epub 2017 Mar 31.
    Department of Internal Medicine, University of Maryland Medical Center, Baltimore, MD, USA.
    Smallpox was eradicated by the World Health Organization in 1980. Before its eradication thedisease had a mortality rate upwards of 50% and had a significant impact on society. During theAmerican Revolutionary war, smallpox outbreaks were impeding the American war effort until1777 when George Washington carried out a mass inoculation campaign in the ContinentalArmy that reduced the mortality from smallpox to less than 2%.

    Vaccination with a codon-optimized A27L-containing plasmid decreases virus replication and dissemination after vaccinia virus challenge.
    Vaccine 2017 Jun 16. Epub 2017 Jun 16.
    Department of Microbiology and Medical Zoology, University of Puerto Rico, Medical Sciences Campus, School of Medicine, San Juan, PR 00936, United States. Electronic address:
    Smallpox is a disease caused by Variola virus (VARV). Although eradicated by WHO in 1980, the threat of using VARV on a bioterror attack has increased. The current smallpox vaccine ACAM2000, which consists of live vaccinia virus (VACV), causes complications in individuals with a compromised immune system or with previously reported skin diseases.

    Induction, treatment and prevention of eczema vaccinatum in atopic dermatitis mouse models.
    Vaccine 2017 Jun 20. Epub 2017 Jun 20.
    Department of Infectious Diseases, Israel Institute for Biological Research (IIBR), Ness-Ziona, Israel. Electronic address:
    Eczema vaccinatum is a severe and occasionally lethal complication of smallpox vaccine, characterized by systemic viral dissemination, distant from the initial inoculation site of the vaccine. A major risk factor for eczema vaccinatum is a background of atopic dermatitis, a chronic, common allergic, relapsing disorder, manifested by dry and inflamed skin, itchy rash, Th2 biased immune response and hypersensitivity to various antigens. Unlike the severe manifestations of eczema vaccinatum in humans, current models present only mild symptoms that limits examination of potential therapeutics for eczema vaccinatum. Read More

    Vaccine hesitancy: parental, professional and public responsibility.
    Ann Ist Super Sanita 2017 Apr-Jun;53(2):157-162
    President, Istituto Superiore di Sanità, Rome, Italy.
    The opposition to vaccinations is a well-known phenomenon that dates back to the Victorian age when it was self-limited by the awareness of the importance to be protected against fearsome infectious diseases. In the XX century, the mass use of vaccination has - instead - consented to eradicate or drastically reduce the burden of diseases such as smallpox and polio. These positive effects of the vaccination campaigns have blurred out, if not erased, the memory of the tragic consequences of the past's widespread diseases, leading people to underestimate the severity of the harm that vaccinations prevent.

    Comparative Efficacy of Intramuscular and Scarification Routes of Administration of Live Smallpox Vaccine in a Murine Challenge Model.
    Vaccine 2017 Jul 9;35(31):3889-3896. Epub 2017 Jun 9.
    CBR Division, Dstl Porton Down, Salisbury SP4 0JQ, UK; The Pirbright Institute, Ash Road, Woking GU24 0NF, UK. Electronic address:
    In recent years concern has mounted regarding the possibility of a re-emergence of smallpox through biowarfare or bioterrorism. There is also concern over the incidence of human monkeypox in endemic areas and the potential for monkeypox to be accidentally transported to non-endemic areas. In the event of re-emergence of smallpox or emergence of monkeypox, the accepted route of administration for live replicating smallpox vaccine is dermal scarification, which generates a virus-shedding lesion that persists for several days at the vaccination site.

    Functional paralysis of GM-CSF-derived bone marrow cells productively infected with ectromelia virus.
    PLoS One 2017 12;12(6):e0179166. Epub 2017 Jun 12.
    Department of Preclinical Sciences, Faculty of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Warsaw, Poland.
    Ectromelia virus (ECTV) is an orthopoxvirus responsible for mousepox, a lethal disease of certain strains of mice that is similar to smallpox in humans, caused by variola virus (VARV). ECTV, similar to VARV, exhibits a narrow host range and has co-evolved with its natural host. Consequently, ECTV employs sophisticated and host-specific strategies to control the immune cells that are important for induction of antiviral immune response. Read More

    Classification of Cowpox Viruses into Several Distinct Clades and Identification of a Novel Lineage.
    Viruses 2017 Jun 10;9(6). Epub 2017 Jun 10.
    Institute of Diagnostic Virology, Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health, Südufer 10, 17493 Greifswald, Germany.
    Cowpox virus (CPXV) was considered as uniform species within the genus Orthopoxvirus (OPV). Previous phylogenetic analysis indicated that CPXV is polyphyletic and isolates may cluster into different clades with two of these clades showing genetic similarities to either variola (VARV) or vaccinia viruses (VACV). Further analyses were initiated to assess both the genetic diversity and the evolutionary background of circulating CPXVs. Read More

    Novel Nonreplicating Vaccinia Virus Vector Enhances Expression of Heterologous Genes and Suppresses Synthesis of Endogenous Viral Proteins.
    MBio 2017 Jun 6;8(3). Epub 2017 Jun 6.
    Laboratory of Viral Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Maryland, USA
    Viruses are used as expression vectors for protein synthesis, immunology research, vaccines, and therapeutics. Advantages of poxvirus vectors include the accommodation of large amounts of heterologous DNA, the presence of a cytoplasmic site of transcription, and high expression levels. On the other hand, competition of approximately 200 viral genes with the target gene for expression and immune recognition may be disadvantageous. Read More

    Duration of neutralizing antibody persisting in Thai individuals after childhood vaccination against smallpox.
    Asian Pac J Allergy Immunol 2017 Jun 1. Epub 2017 Jun 1.
    Department of Microbiology, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
    Background: Although smallpox was completely eliminated by 1980, it remains possible that variola virus could be intentionally released in an act of bioterrorism. Thus, several studies have been performed to detect antibody levels after smallpox vaccination of the current population in various countries to indicate the duration of maintenance of immunological memory. Our study endeavored to investigate the level of neutralizing (Nt) antibody responses of Thai individuals who had been immunized with smallpox vaccine during childhood. Read More

    Voluntary Vaccination through Self-organizing Behaviors on Locally-mixed Social Networks.
    Sci Rep 2017 Jun 1;7(1):2665. Epub 2017 Jun 1.
    School of Cyberspace, Hangzhou Dianzi University, Hangzhou, 310018, China.
    Voluntary vaccination reflects how individuals weigh the risk of infection and the cost of vaccination against the spread of vaccine-preventable diseases, such as smallpox and measles. In a homogeneously mixing population, the infection risk of an individual depends largely on the proportion of vaccinated individuals due to the effects of herd immunity. While in a structured population, the infection risk can also be affected by the structure of individuals' social network. Read More

    [The court physician, the clergyman, a learned society and smallpox].
    Ned Tijdschr Geneeskd 2017 ;161(0):D1111
    Universiteit Maastricht, Onderwijsinstituut Faculty of Health, Medicine and Life Sciences, Maastricht.
    Variolation was introduced in England in the first half of the 18th century. The positive effects of this new method for preventing smallpox were already known in the Netherlands around 1720, one of whom was the Dutch physician Boerhaave. In spite of this, it took another 30 years before variolation was used in the Netherlands. Read More

    Considering the "public" in public health: popular resistance to the Smallpox Eradication Programme in India.
    Indian J Med Ethics 2017 Apr-Jun;2(2):104-111
    Associate Professor, Department of Geography, 123 Major Williams Hall, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061 USA,.
    Public health initiatives, including large-scale vaccination and disease eradication programmes, regularly pit the rights of the individual against broader benefits to society. At times, the public resists such initiatives, with the World Health Organisation's Smallpox Eradication Programme (SEP) in India being a case in point. Here, we critically investigate resistance to smallpox vaccines in India and argue that while the SEP successfully eradicated a global killer; individuals were stripped of human rights through coercion, forcible vaccination and quarantine.

    Ethical and legal challenges of vaccines and vaccination: Reflections.
    Indian J Med Ethics 2017 Apr-Jun;2(2):72-74
    Advocate, Courtyard Attorneys, 47/1345, MIG Adarsh Nagar, Worli, Mumbai 400 030 India,.
    Vaccines and vaccination have emerged as key medical scientific tools for prevention of certain diseases. Documentation of the history of vaccination shows that the initial popular resistance to universal vaccination was based on false assumptions and eventually gave way to acceptance of vaccines and trust in their ability to save lives. The successes of the global eradication of smallpox, and now of polio, have only strengthened the premier position occupied by vaccines in disease prevention. Read More

    Cowpox virus: What's in a Name?
    Viruses 2017 May 9;9(5). Epub 2017 May 9.
    Bundeswehr Institute of Microbiology, Neuherbergstr 11, 80937 Munich, Germany.
    Traditionally, virus taxonomy relied on phenotypic properties; however, a sequence-based virus taxonomy has become essential since the recent requirement of a species to exhibit monophyly. The species Cowpox virus has failed to meet this requirement, necessitating a reexamination of this species. Here, we report the genomic sequences of nine Cowpox viruses and, by combining them with the available data of 37 additional genomes, confirm polyphyly of Cowpox viruses and find statistical support based on genetic data for more than a dozen species.

    A medical enigma : what "gale chinoise (Chinese scabies)" meant 150 years ago.
    Med Sante Trop 2017 May 4. Epub 2017 May 4.
    Centre René Labusquière, Université de Bordeaux 3, Bordeaux, France.
    Context: The meaning of the term "gale chinoise" mentioned in some articles about French overseas territories in the 19th century, remains unclear. In response to a query of an American colleague dermatologist trying to find out what it meant 150 years ago, we attempted to elucidate the nature of this ancient disease, which today would be translated literally as Chinese scabies.

    Method: We submitted the query to a panel of civilian and military French tropical medicine specialists including dermatologists, through two networks : Association Amicale Santé Navale et d'Outre-Mer and Société de Pathologie Exotique. Read More

    Key Laboratory of Nuclear Medicine, Ministry of Health, Jiangsu Key Laboratory of Molecular Nuclear Medicine, Jiangsu Institute of Nuclear Medicine, Wuxi, Jiangsu, China.
    Oncolytic virotherapy is being developed as a promising platform for cancer therapy due to its ability to lyse cancer cells in a tumor-specific manner. Vaccinia virus has been used as a live vaccine in the smallpox eradication program and now is being potential in cancer therapy with a great safety profile. Vaccinia strain Guang9 (VG9) is an attenuated Chinese vaccinia virus and its oncolytic efficacy has been evaluated in our previous study. Read More

    Ivermectin and malaria control.
    Malar J 2017 Apr 24;16(1):172. Epub 2017 Apr 24.
    Graduate School of Infection Control Sciences, Kitasato University, 5-9-1 Shirokane, Minato-ku, Tokyo, 108-8641, Japan.
    As the world begins to realize the very real prospect of eliminating malaria as a public health problem globally, the scientific community is acutely aware that novel and innovative new tools will be required if that lofty goal is to be accomplished. Moreover, the need for comprehensive, integrated products and interventions is being recognized in order for the critical 'final steps' toward elimination to be taken successfully. Failure to take these crucial last steps have dogged all past global disease elimination programmes, except for smallpox. Read More

    Review of poxvirus: emergence of monkeypox.
    Med Sante Trop 2017 Feb;27(1):29-39
    Service de dermatologie, HIA Sainte-Anne, Toulon, France.
    This article reviews the different types of poxvirus infections. Smallpox, although eradicated, must continue to be monitored because of the potential risk of accidental or voluntary (by bioterrorism) reintroduction. Monkeypox and cowpox viruses are considered to be emergent today ; their high risk of dissemination is due to the increase in international transport as well as trends for new animals as pets and the loss of vaccinal protection against smallpox.

    Preparing for biological threats: Addressing the needs of pregnant women.
    Birth Defects Res 2017 Mar;109(5):391-398
    Centers for Disease Control and Prevention, Atlanta, Georgia.
    Intentional release of infectious agents and biological weapons to cause illness and death has the potential to greatly impact pregnant women and their fetuses. We review what is known about the maternal and fetal effects of seven biological threats: Bacillus anthracis (anthrax); variola virus (smallpox); Clostridium botulinum toxin (botulism); Burkholderia mallei (glanders) and Burkholderia pseudomallei (melioidosis); Yersinia pestis (plague); Francisella tularensis (tularemia); and Rickettsia prowazekii (typhus). Evaluating the potential maternal, fetal, and infant consequences of an intentional release of an infectious agent requires an assessment of several key issues: (1) are pregnant women more susceptible to infection or illness compared to the general population?; (2) are pregnant women at increased risk for severe illness, morbidity, and mortality compared to the general population?; (3) does infection or illness during pregnancy place women, the fetus, or the infant at increased risk for adverse outcomes and how does this affect clinical management?; and (4) are the medical countermeasures recommended for the general population safe and effective during pregnancy? These issues help frame national guidance for the care of pregnant women during an intentional release of a biological threat. Read More

    Relocating Pastorian Medicine: Accommodation and Acclimatization of Pastorian Practices against Smallpox at the Pasteur Institute of Chengdu, China, 1908-1927.
    Sci Context 2017 Mar;30(1):33-59
    Department of History,University of California,Los
    Argument Revising the diffusionist view of current scholarship on the Pasteur Institutes in China, this paper demonstrates the ways in which local networks and circumstances informed the circulation and construction of knowledge and practices relating to smallpox prophylaxis in the Southwest of China during the early twentieth century. I argue that the Pasteur Institute of Chengdu did not operate in a natural continuity with the preceding local French medical institutions, but rather presented an intentional break from them. This Institute, as the first established by the French in China, strove for political and administrative independence both from the Chinese authority and from the Catholic Church. Read More

    Efficacy of delayed brincidofovir treatment against a lethal rabbitpox virus challenge in New Zealand White rabbits.
    Antiviral Res 2017 Jul 7;143:278-286. Epub 2017 Apr 7.
    Chimerix, Durham, NC, USA.
    In the event of a bioterror attack with variola virus (smallpox), exposure may only be identified following onset of fever. To determine if antiviral therapy with brincidofovir (BCV; CMX001) initiated at, or following, onset of fever could prevent severe illness and death, a lethal rabbitpox model was used. BCV is in advanced development as an antiviral for the treatment of smallpox under the US Food and Drug Administration's 'Animal Rule'. Read More

    Generation and Production of Modified Vaccinia Virus Ankara (MVA) as a Vaccine Vector.
    Methods Mol Biol 2017 ;1581:97-119
    The Jenner Institute, University of Oxford, Research Bldg., Old Road Campus, ORCRB, Oxford, OX3 7DQ, UK.
    The smallpox vaccine based on the vaccinia virus was successfully used to eradicate smallpox, but although very effective, it was a very reactogenic vaccine and responsible for the deaths of one to two people per million vaccinated. Modified Vaccinia virus Ankara (MVA) is an attenuated derivative, also used in the smallpox eradication campaign and now being developed as a recombinant viral vector to produce vaccines against infectious diseases and cancer. MVA can encode one or more foreign antigens and thus can function as a multivalent vaccine. Read More

    Vaccinia virus evasion of regulated cell death.
    Immunol Lett 2017 Jun 31;186:68-80. Epub 2017 Mar 31.
    Department of Pathology, University of Cambridge, Cambridge CB2 1QP, United Kingdom. Electronic address:
    Regulated cell death is a powerful anti-viral mechanism capable of aborting the virus replicative cycle and alerting neighbouring cells to the threat of infection. The biological importance of regulated cell death is illustrated by the rich repertoire of host signalling cascades causing cell death and by the multiple strategies exhibited by viruses to block death signal transduction and preserve cell viability. Vaccinia virus (VACV), a poxvirus and the vaccine used to eradicate smallpox, encodes multiple proteins that interfere with apoptotic, necroptotic and pyroptotic signalling. Read More

    The origins of the vaccine cold chain and a glimpse of the future.
    Vaccine 2017 Apr;35(17):2115-2120
    7 Avenue Pasteur 71700 Tournus, France. Electronic address:
    International efforts to eradicate smallpox in the 1960s and 1970s provided the foundation for efforts to expand immunization programmes, including work to develop immunization supply chains. The need to create a reliable system to keep vaccines cold during the lengthy journey from the manufacturer to the point of use, even in remote areas, was a crucial concern during the early days of the Expanded Programme on Immunization. The vaccine cold chain was deliberately separated from other medical distribution systems to assure timely access to and control of vaccines and injection materials. Read More

    Variola minor in coalfield areas of England and Wales, 1921-34: Geographical determinants of a national smallpox epidemic that spread out of effective control.
    Soc Sci Med 2017 May 23;180:160-169. Epub 2017 Mar 23.
    Department of Geography, University of Cambridge, Downing Place, Cambridge, CB2 3EN, UK.
    This paper uses techniques of binary logistic regression to identify the spatial determinants of the last national epidemic of smallpox to spread in England and Wales, the variola minor epidemic of 1921-34. Adjusting for age and county-level variations in vaccination coverage in infancy, the analysis identifies a dose-response gradient with increasing odds of elevated smallpox rates in local government areas with (i) medium (odds ratio [OR] = 5.32, 95% Confidence Interval [95% CI] 1.

    Science Department, University College Roosevelt.
    The immune system contributes to the maintenance of health by preventing and limiting the clinical consequences of infections by pathogenic microorganisms. During the evolution of Homo sapiens, those with the fittest immune system survived. The immune system of Homo sapiens was further improved and adapted by admixture with Neanderthal genes. Read More

    Digital triplex DNA assay based on plasmonic nanocrystals.
    Anal Bioanal Chem 2017 May 22;409(14):3657-3666. Epub 2017 Mar 22.
    Institute of Optical Imaging and Sensing, Shenzhen Key Laboratory for Minimal Invasive Medical Technologies, Graduate School at Shenzhen, Tsinghua University, Shenzhen, Guangdong, 518055, China.
    A new analytical method has been developed to detect three kinds of DNA simultaneously based on magnetic beads and color-encoded plasmonic nanocrystals. Magnetic beads modified with capture DNA are employed to collect the specific target DNA, and color-encoded plasmonic nanocrystals are applied to signal the target through DNA hybridization. As a proof of concept, three types of representative metal nanocrystals of gold nanoparticle (AuNP), gold nanorod (AuNR), and gold/silver nanoparticle (Au/AgNP) were employed to signal three dissimilar virus-related protective antigen genes, Ebola virus (EV), Variola virus (VV), and Bacillus anthracis (BA), respectively.

    Monkeypox Virus Host Factor Screen Using Haploid Cells Identifies Essential Role of GARP Complex in Extracellular Virus Formation.
    J Virol 2017 Jun 12;91(11). Epub 2017 May 12.
    Poxvirus and Rabies Branch, Division of High Consequence Pathogens and Pathology, Centers for Disease Control and Prevention, Atlanta, Georgia, USA
    Monkeypox virus (MPXV) is a human pathogen that is a member of the Orthopoxvirus genus, which includes Vaccinia virus and Variola virus (the causative agent of smallpox). Human monkeypox is considered an emerging zoonotic infectious disease. To identify host factors required for MPXV infection, we performed a genome-wide insertional mutagenesis screen in human haploid cells. Read More

    Novel Orthopoxvirus Infection in an Alaska Resident.
    Clin Infect Dis 2017 Jun;64(12):1737-1741
    Alaska Division of Public Health, Section of Epidemiology, Anchorage.
    Background.: Human infection by orthopoxviruses is being reported with increasing frequency, attributed in part to the cessation of smallpox vaccination and concomitant waning of population-level immunity. In July 2015, a female resident of interior Alaska presented to an urgent care clinic with a dermal lesion consistent with poxvirus infection. Read More

    Treacle and Smallpox: Two Tests for Multicriteria Decision Analysis Models in Health Technology Assessment.
    Value Health 2017 Mar 20;20(3):512-515. Epub 2016 Dec 20.
    Department of Management Science, University of Strathclyde Business School, Glasgow, UK. Electronic address:
    Multicriteria decision analysis (MCDA) is rightly receiving increasing attention in health technology assessment. Nevertheless, a distinguishing feature of the health domain is that technologies must actually improve health, and good performance on other criteria cannot compensate for failure to do so. We argue for two reasonable tests for MCDA models: the treacle test (can a winning intervention be incompletely ineffective?) and the smallpox test (can a winning intervention be for a disease that no one suffers from?). Read More

    We strongly support childhood immunisation-statement from the European Academy of Paediatrics (EAP).
    Eur J Pediatr 2017 May 10;176(5):679-680. Epub 2017 Mar 10.
    Department Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden.
    The eradication of smallpox and the elimination of several other infectious diseases from much of the world has provided convincing evidence that vaccines are among the most effective interventions for promoting health. The current scepticism about immunisation among members of the new US administration carries a risk of decreasing immunisation rates also in Europe. While only a small minority of the population are strongly anti-vaccine, their public activities have significantly influenced an uncertainty among the general population about both the safety of and the necessity for vaccination.

    Antibody Recognition of Immunodominant Vaccinia Virus Envelope Proteins.
    Subcell Biochem 2017 ;83:103-126
    Division of Cell Biology, La Jolla Institute for Allergy and Immunology (LJI), La Jolla, CA, 92037, USA.
    Vaccinia Virus (VACV) is an enveloped double stranded DNA virus and the active ingredient of the smallpox vaccine. The systematic administration of this vaccine led to the eradication of circulating smallpox (variola virus, VARV) from the human population. As a tribute to its success, global immunization was ended in the late 1970s. Read More

    Safety and immunogenicity of a modified vaccinia Ankara vaccine using three immunization schedules and two modes of delivery: A randomized clinical non-inferiority trial.
    Vaccine 2017 Mar 27;35(13):1675-1682. Epub 2017 Feb 27.
    The Emmes Corporation, Rockville, MD, United States.
    Introduction: To guide the use of modified vaccinia Ankara (MVA) vaccine in response to a release of smallpox virus, the immunogenicity and safety of shorter vaccination intervals, and administration by jet injector (JI), were compared to the standard schedule of administration on Days 1 and 29 by syringe and needle (S&N).

    Methods: Healthy adults 18-40years of age were randomly assigned to receive MVA vaccine subcutaneously by S&N on Days 1 and 29 (standard), Days 1 and 15, or Days 1 and 22, or to receive the vaccine subcutaneously by JI on Days 1 and 29. Blood was collected at four time points after the second vaccination for plaque reduction neutralization test (PRNT) (primary endpoint) and ELISA (secondary endpoint) antibody assays. Read More

    NIH Common Fund Eastern Regional Comprehensive Metabolomics Resource Core, RTI International, 3040 E Cornwallis Road, Research Triangle Park, NC 27709, USA. Electronic address:
    An Adverse Event Following Immunization (AEFI) is an adverse reaction to a vaccination that goes above and beyond the usual side effects associated with vaccinations. One serious AEFI related to the smallpox vaccine is myopericarditis. Metabolomics involves the study of the low molecular weight metabolite profile of cells, tissues, and biological fluids, and provides a functional readout of the phenotype. Read More

    Socio-ecological dynamics and challenges to the governance of Neglected Tropical Disease control.
    Infect Dis Poverty 2017 Feb 6;6(1):35. Epub 2017 Feb 6.
    Department of International Development, London School of Economics and Political Science, London, UK.
    The current global attempts to control the so-called "Neglected Tropical Diseases (NTDs)" have the potential to significantly reduce the morbidity suffered by some of the world's poorest communities. However, the governance of these control programmes is driven by a managerial rationality that assumes predictability of proposed interventions, and which thus primarily seeks to improve the cost-effectiveness of implementation by measuring performance in terms of pre-determined outputs. Here, we argue that this approach has reinforced the narrow normal-science model for controlling parasitic diseases, and in doing so fails to address the complex dynamics, uncertainty and socio-ecological context-specificity that invariably underlie parasite transmission.

    Safety of live vaccinations on immunosuppressive therapy in patients with immune-mediated inflammatory diseases, solid organ transplantation or after bone-marrow transplantation - A systematic review of randomized trials, observational studies and case reports.
    Vaccine 2017 Mar 3;35(9):1216-1226. Epub 2017 Feb 3.
    Department of Public Health, Division of Infectious Diseases/Travel Clinic, Epidemiology, Biostatistics and Prevention Institute, Hirschengraben 84, 8001 Zurich, Switzerland. Electronic address:
    Background: Live vaccines are generally contraindicated on immunosuppressive therapy due to safety concerns. However, data are limited to corroborate this practice.

    Objectives: To estimate the safety of live vaccinations in patients with immune-mediated inflammatory diseases (IMID) or solid organ transplantation (SOT) on immunosuppressive treatment and in patients after bone-marrow transplantation (BMT). Read More

    A rapid Orthopoxvirus purification protocol suitable for high-containment laboratories.
    J Virol Methods 2017 May 26;243:68-73. Epub 2017 Jan 26.
    Poxvirus and Rabies Branch, Division of High-Consequence Pathogens and Pathology, National Center for Emerging Zoonotic Infectious Diseases, Centers for Disease Control and Prevention, Atlanta, GA 30329, USA.
    Virus purification in a high-containment setting provides unique challenges due to barrier precautions and operational safety approaches that are not necessary in lower biosafety level (BSL) 2 environments. The need for high risk group pathogen diagnostic assay development, anti-viral research, pathogenesis and vaccine efficacy research necessitates work in BSL-3 and BSL-4 labs with infectious agents. When this work is performed in accordance with BSL-4 practices, modifications are often required in standard protocols. Read More

    Short-term clinical safety profile of brincidofovir: A favorable benefit-risk proposition in the treatment of smallpox.
    Antiviral Res 2017 Jul 14;143:269-277. Epub 2017 Jan 14.
    Chimerix, Durham, NC, USA.
    Brincidofovir (BCV, CMX001) is an orally available, long-acting, broad-spectrum antiviral that has been evaluated in healthy subjects in Phase I studies and in hematopoietic cell transplant recipients and other immunocompromised patients in Phase II/III clinical trials for the prevention and treatment of cytomegalovirus and adenovirus infections. BCV has also shown in vitro activity against orthopoxviruses such as variola (smallpox) virus, and is under advanced development as a treatment for smallpox under the US FDA's 'Animal Rule'. The anticipated treatment regimen for smallpox is a total weekly dose of 200 mg administered orally for 3 consecutive weeks. Read More

    Cutaneous Deficiency of Filaggrin and STAT3 Exacerbates Vaccinia Disease In Vivo.
    PLoS One 2017 12;12(1):e0170070. Epub 2017 Jan 12.
    Food and Drug Administration, Center for Biologics Evaluation and Research, 10903 New Hampshire Ave., Silver Spring, MD, United States of America.
    Rationale: Defects in filaggrin and STAT3 are associated with atopic dermatitis (AD) and susceptibility to severe skin infection.

    Methods: We evaluated skin infection with the current smallpox vaccine, ACAM-2000, in immunosuppressed mice with combined cutaneous deficiency in filaggrin and STAT3. In parallel, early events post-infection with ACAM-2000 were investigated in cultured keratinocytes in which filaggrin expression was knocked down via siRNA. Read More

    Safety tested Modified Vaccinia virus Ankara (MVA) is licensed as third-generation vaccine against smallpox and serves as a potent vector system for development of new candidate vaccines against infectious diseases and cancer. Historically, MVA was developed by serial tissue culture passage in primary chicken cells of vaccinia virus strain Ankara, and clinically used to avoid the undesirable side effects of conventional smallpox vaccination. Adapted to growth in avian cells MVA lost the ability to replicate in mammalian hosts and lacks many of the genes orthopoxviruses use to conquer their host (cell) environment. Read More

    Modified Vaccinia virus has been shown to be a safe and immunogenic vector platform for delivery of HIV vaccines. Use of this vector is of particular importance to the military, with the implementation of a large scale smallpox vaccination campaign in 2002 in active duty and key civilian personnel in response to potential bioterrorist activities. Humoral immunity to smallpox vaccination was previously shown to be long lasting (up to 75 years) and protective. Read More
