Studies on a single-dose capsule preparation of Poliomyelitis vaccine. 1966

J M Barnes, and N S Galbraith

In view of certain difficulties involved in the administration of poliomyelitis vaccine in liquid form on sugar or in syrup in mass campaigns, trials have been conducted with a new single-dose preparation of live attenuated poliovaccine (Sabin strain) in an emulsion in a gelatin capsule. Each capsule contained a standard dose of vaccine which was shown to be stable in this form. It has been demonstrated that the capsule vaccine was as effective as liquid vaccine both in children and in adults. The capsules were acceptable to adults and children over the age of 5 years, but between 6% and 7% of 4-5-year-old children refused the vaccine in this form owing to difficulty in swallowing the capsules.The authors consider that the capsule may be recommended for the routine immunization of older children and adults and for mass vaccination campaigns. It is suggested that the vaccine could be administered to young children and babies in the course of such campaigns by opening the capsule and mixing the contents with water or sweetened liquid in a spoon.

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.

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.
