title: [Assessment of the effectiveness of different methoods of immunization with live plague vaccine EB in aerosol infections].
abstract: The work deals with the results of the comparative evaluation of the effectiveness of vaccines developed at the Sanitary Research Institute (Zagorsk) and the Mechnikov Research Institute for Vaccines and Sera (Moscow), as well as two methods of immunization against plague, by inhalation and subcutaneous injection, under the conditions of aerosol infection. The immunogenic effectiveness of both vaccines, when evaluated in terms of LD50, was shown to be approximately the same, but the animals immunized by the inhalation method with the vaccine developed at the Sanitary Research Institute proved to be less susceptible to infection than those immunized with the vaccine developed at the Mechnikov Research Institute for Vaccines and Sera in Moscow. After immunization by the inhalation method the vaccine developed at the Sanitary Research Institute rendered more effective protection (3- to 4-fold) against aerosol infection than after immunization by subcutaneous injection. The animals immunized by the inhalation method proved to be capable of surviving plague in the primary pneumonic form.
