Poxviruses: smallpox vaccine, its complications and chemotherapy
Department of Pathogenic Bacteria, The Stephan Angeloff Institute of Microbiology, Bulgarian Academy of Sciences, Sofia, Bulgaria
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 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. 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
