[The efficacy of a cultured rabies vaccine studied in guinea pigs preliminarily infected with a fixed rabies virus].

In experiments of curative vaccination, carried out with the use of an experimental model similar to the current practice of treatment with antirabies preparations, the advantages of using tissue-culture rabies vaccine with immunogenic potency equal to 1.3 international units (I. U.

[The efficacy of a cultured rabies vaccine studied on guinea pigs previously infected with the rabies street virus].

In this work materials on the development of an experimental model for the study of rabies vaccines are presented. The comparative study of different immunization schedules for vaccines with different protective potency has been carried out. Guinea pigs infected with street rabies virus, strain k, were used as an experimental model.

[A new rabies vaccine in public health practice in the USSR].

A new antirabies vaccine prepared on the basis of virus grown in the ovine brain, purified from 85-90% of brain-tissue ballast substances and inactivated with beta-propilactone has been developed at the Moscow Research Institute of Viral preparations (USSR Acad. Med. Sci.

[Reactogenicity and antigenic activity of a chromatographic cultured purified and concentrated inactivated dried vaccine against tick-borne encephalitis].

The study of the characteristics of a new dried tissue-culture purified concentrated inactivated vaccine against tick-borne encephalitis, manufactured in the USSR, has revealed that the preparation is moderately reactogenic and produces no definite side effects in the vaccinees. In the process of the controlled epidemiological trial the optimum vaccination schedule for the primary immunization of adults against tick-borne encephalitis with the new preparation has been determined by the study of serum samples from the vaccinees in the hemagglutination inhibition test and the neutralization test in tissue culture. In accordance with this vaccination schedule the course of primary immunization with the chromatographic variant of the concentrated vaccine consists of two injections in a dose of 0.
