[Determination of the optimal dose of a cultured inactivated vaccine for preventing Japanese encephalitis]. / Opredelenie optimal'noi dozy kul'tural'noi inaktivirovannoi vaktsiny dlia profilaktiki iaponskogo éntsefalita.

The article presents the summarized results of the controlled field trial of a new inactivated liquid absorbed tissue-culture vaccine developed in the USSR. The optimal immunization dose has been determined: 1.5 ml of the vaccine introduced with a syringe or a jet injector. The intensity and character of postvaccinal immunity have been studied.

[Comparative study of the reactogenicity and immunogenicity of new Soviet and commercial vaccines for preventing Japanese encephalitis]. / Sravnitel'noe izuchenie reaktogennosti i immunogennosti novykh otechestvennykh i kommercheskikh vaktsin dlia profilaktiki iaponskogo éntsefalita.

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.
