[Comparative study of the reactogenicity and immunogenicity of new Soviet and commercial vaccines for preventing Japanese encephalitis].

In this article the results of testing Soviet vaccines for the prophylaxis of Japanese encephalitis, cell-culture inactivated adsorbed liquid vaccine and brain-tissue purified dried vaccine, are generalized and the comparison of their reactogenicity and immunogenicity characteristics with those of a similar commercial preparation manufactured by Toshiba Kagaku Kogyo Co., Ltd. (Japan) is made. Cell-culture inactivated liquid vaccine has proved to be the optimal preparation: it produces the most prolonged and intensive immunity and, when introduced by two methods, shows low reactogenicity.
