[Comparative study of the safety, reactogenicity and antigenic activity of chemical and live brucellosis vaccines in a controlled epidemiological trial].
The complex evaluation of the reactogenicity characteristics revealed that after immunization with chemical brucellosis vaccine systemic reactions observed in most of the vaccinees were mildly pronounced and local reactions, mildly and moderately pronounced, their duration not exceeding 48-72 hours. During 4 months after immunization the antigenic and immunogenic potency of chemical brucellosis vaccine was no different from that of live brucellosis vaccine; seropositive persons immunized with chemical and live brucellosis vaccines showed no statistically significant differences in the geometric mean of their antibody titers, as determined in a number of serological tests, for a year after immunization. The examination of the vaccinees 4 and 12 months after immunization revealed that the sensitizing activity of chemical brucellosis vaccine was, respectively, 12.2 and 2.5 times lower than the allergenic action of live brucellosis vaccine.
