  • Poxviruses: Smallpox Vaccine, Its Complications and Chemotherapy
    Virus Adaptation and Treatment Dovepress open access to scientific and medical research Open Access Full Text Article R E V IEW Poxviruses: smallpox vaccine, its complications and chemotherapy Mimi Remichkova Abstract: The threat of bioterrorism in the recent years has once again posed to mankind the unresolved problems of contagious diseases, well forgotten in the past. Smallpox (variola) is Department of Pathogenic Bacteria, The Stephan Angeloff Institute among the most dangerous and highly contagious viral infections affecting humans. The last of Microbiology, Bulgarian Academy natural case in Somalia marked the end of a successful World Health Organization campaign of Sciences, Sofia, Bulgaria 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 For personal use only. the population in case of eventual terrorist attack. This review describes the characteristic features of the poxviruses, smallpox vaccination, its adverse reactions, and poxvirus chemotherapy. Keywords: poxvirus, smallpox vaccine, post vaccine complications, inhibitors Characteristics of poxviruses Smallpox (variola) infection is caused by the smallpox virus. This virus belongs to the genus of Orthopoxvirus included in the Poxviridae family. Poxviruses are one of the largest and most complexly structured viruses, known so far. The genome of poxviruses consists of a linear two-chained DNA and its replication takes place in the cytoplasm of the infected cell.

  • Vaccinia Belongs to a Family of Viruses That Is Closely Related to the Smallpox Virus
    VACCINIA INFECTION What is it? Vaccinia belongs to a family of viruses that is closely related to the smallpox virus. Because of the similarities between the smallpox and vaccinia viruses, the vaccinia virus is used in the smallpox vaccine. When this virus is used as a vaccine, it allows our immune systems to develop immunity against smallpox. The smallpox vaccine does not actually contain smallpox virus and cannot cause smallpox. Vaccination usually prevents smallpox infection for at least ten years. The vaccinia vaccine against smallpox was used to successfully eradicate smallpox from the human population. More recently, this virus has also become of interest due to concerns about smallpox being used as an agent of bioterrorism. How is the virus spread? Vaccinia can be spread by touching the vaccination site before it has fully healed or by touching clothing or bandages that have been contaminated with the live virus during vaccination. In this manner, vaccinia can spread to other parts of the body and to other individuals. It cannot be spread through the air. What are the symptoms of vaccinia? Vaccinia virus symptoms are similar to smallpox, but milder. Vaccinia may cause rash, fever, headache and body aches. In certain individuals, such as those with weak immune systems, the symptoms can be more severe. What are the potential side effects of the vaccinia vaccine for smallpox? Normal reactions are mild and go away without any treatment.These include: Soreness and redness in the arm where the vaccine was given Slightly swollen, sore glands in the armpits Low grade fever One in approximately three people will feel badly enough to miss school, work or recreational activities Trouble sleeping Serious reactions are not very common but can occur in about 1,000 in every 1 million people who are vaccinated for the first time.

Received: 10 November 2010; in revised form: 9 December 2010 / Accepted: 10 December 2010 / Published: 22 December 2010 Abstract: Cidofovir [(S)-1-(3-hydroxy-2-phosphonylmethoxypropyl)cytosine, HPMPC] is an acyclic nucleoside analog approved since 1996 for clinical use in the treatment of cytomegalovirus (CMV) retinitis in AIDS patients. Cidofovir (CDV) has broad-spectrum activity against DNA viruses, including herpes-, adeno-, polyoma-, papilloma- and poxviruses. Among poxviruses, cidofovir has shown in vitro activity against orthopox [vaccinia, variola (smallpox), cowpox, monkeypox, camelpox, ectromelia], molluscipox [molluscum contagiosum] and parapox [orf] viruses. The anti-poxvirus activity of cidofovir in vivo has been shown in different models of infection when the compound was administered either intraperitoneal, intranasal (aerosolized) or topically. In humans, cidofovir has been successfully used for the treatment of recalcitrant molluscum contagiosum virus and orf virus in immunocompromised patients. CDV remains a reference compound against poxviruses and holds potential for the therapy and short-term prophylaxis of not only orthopox- but also parapox- and molluscipoxvirus infections. Keywords: cidofovir; poxviruses; acyclic nucleoside analog 1.

  • (ACIP) General Best Guidance for Immunization
    Appendix 1: Glossary Adverse event. An undesirable medical condition that occurs following vaccination which might be truly caused by a vaccine, or it might be pure coincidence. Adverse reaction. An undesirable medical condition that has been demonstrated to be caused by a vaccine. Evidence for the causal relation is usually obtained through randomized clinical trials, controlled epidemiologic studies, isolation of the vaccine strain from the pathogenic site, or recurrence of the condition with repeated vaccination (i.e., rechallenge); synonyms include side effect and adverse effect. Adjuvant. A vaccine component distinct from the antigen that enhances the immune response to the antigen. Antitoxin. A solution of antibodies against a toxin. Antitoxin can be derived from either human (e.g., tetanus immune globulin) or animal (usually equine) sources (e.g., diphtheria and botulism antitoxin). Antitoxins are used to confer passive immunity and for treatment. Hyperimmune globulin (specific). Special preparations obtained from blood plasma from donor pools preselected for a high antibody content against a specific antigen (e.g., hepatitis B immune globulin, varicella-zoster immune globulin, rabies immune globulin, tetanus immune globulin, vaccinia immune globulin, cytomegalovirus immune globulin, botulism immune globulin). Immune globulin. A sterile solution containing antibodies, which are usually obtained from human blood. It is obtained by cold ethanol fractionation of large pools of blood plasma and contains 15%-18% protein. Intended for intramuscular administration, immune globulin is primarily indicated for routine maintenance of immunity among certain immunodeficient persons and for passive protection against measles and hepatitis A.

Additional Information - Selected References..........Pages 9 - 15 Page -1- INVESTIGATOR’S BROCHURE INTRODUCTION This Investigational New Drug Application is being filed in order to make existing stocks of Vaccinia Immune Globulin available for treatment of complications of vaccinia vaccination or exposure to vaccinia or related pox viruses. Vaccinia Immune Globulin (VIG) (Human) is an isotonic sterile solution of the immunoglobulin fraction of plasma from persons vaccinated with vaccinia vaccine. The current lot, 0448A101A, was released as a licensed product by Baxter Healthcare Corporation in 1995. In 1998 a slight discoloration was noted in this product and the FDA placed a hold on its release. Consequently, VIG can no longer be entered into interstate commerce under terms of the approved license and must therefore revert to IND (investigational new drug) status. CDC follows the June 22, 2001 Recommendations of the Immunization Practices Advisory Committee (ACIP) for Vaccinia (Smallpox) Vaccine. Since 1983 CDC has provided vaccinia vaccine for laboratory workers directly involved with smallpox or closely related orthopox viruses (e.g., monkeypox and vaccinia). Due to clinical trials involving recombinant vaccinia virus vaccines, health-care workers (e.g., physicians and nurses) may now be exposed to vaccinia and recombinant vaccinia viruses and may be considered for vaccinia vaccination.

Forty years after the eradication of smallpox, emerging zoonotic orthopoxviruses, such as monkeypox, cowpox, and vaccinia viruses continue to infect humans as well as wild and domestic animals. Currently, the geographical distribution of poxviruses in a broad range of hosts worldwide raises concerns regarding the possibility of outbreaks or viral dissemination to new geographical regions. Here, we review the global host ranges and current epidemiological understanding of zoonotic orthopoxviruses while focusing on orthopoxviruses with epidemic potential, including monkeypox, cowpox, and vaccinia viruses.
