title: [Comparative study of smallpox vaccines from strains B-51, EM-63 and L-IVP in a controlled epidemiologic trial. I. Reactogenic characteristics of the smallpox vaccines].
abstract: A comparative study of smallpox vaccines prepared from the l-ivp zm-63 and b-51 strains was carried out under conditions of controlled epidemiological trial. Children subject to planned vaccination were scarified with commercial batches of the preparations under study (with the same infectious activity). As a result of investigations it was found that in the group of those scarified with the vaccine from zm-63 strain strong local and catarrhal reactions and some disturbances of general condition were more frequent than in those scarified with preparations from the l-ivp and b-51 strain. Along with this, the temperature elevation of various intensity showed no statistically significant difference in the groups a vaccinated with the vaccines compared. Integral analysis of signs characterising different manifestations of reactigenic properties of the vaccines compared led to the conclusion that preparations made of zm-6 strain had greater reactogenic properties.
