title: [Dynamics of the antismallpox antibodies detectable in the passive hemagglutination reaction with various animal immunization schemes].
abstract: Dynamics of accumulation and preservation of antibodies detectable in the PHAT (PHAT-AT) was studied on rabbits and guinea pigs with the use of various doses of the living inactivated virus and their combination in comparison with the virus-neutralizing antibodies, antihemagglutinins and precipitins. Accumulation of the virus-neutralizing antibodies did not coincide in time with the curve of the PHAT-AT accumulation; the titres of the virus-neutralizing antibodies were higher than the PHAT-AT titres. At the same time the percentage of seroconversions determined by PHAT was equal to 100 and the PHAT-AT level directly depended on the immunizing dose, the time of administration and the type of the antigen. On the basis of the data obtained PHAT could be recommended as a test for the assessment of the immunological efficacy of the smallpox vaccinations.
