Immunization against poliomyelitis: risk/benefit/cost in a changing context. 1979

J Salk

Benefit/risk factors in immunization against poliomyelitis are examined from the viewpoint of the relative risk and efficacy of killed and live poliovirus vaccines in the currently changing contexts of poliomyelitis prevalence in developed and developing countries. Risk factors include virus of vaccine origin gaining access to the CNS, and failure of the vaccine to immunize. Data are presented to illustrate the degree to which the respective risks occur in developed and developing countries. The ultimate elimination of risk by eradication of wild and vaccine virus from the population is discussed.

UI MeSH Term Description Entries
D007223 Infant A child between 1 and 23 months of age. Infants
D011051 Poliomyelitis An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses.

D011054 Poliovirus Vaccine, Inactivated A suspension of formalin-inactivated poliovirus grown in monkey kidney cell tissue culture and used to prevent POLIOMYELITIS. Salk Vaccine,Inactivated Poliovirus Vaccine,Vaccine, Inactivated Poliovirus,Vaccine, Salk
D011055 Poliovirus Vaccine, Oral A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts.
