Abstract: Studies have been conducted in unfavorable farm for brucellosis Agricultural Production Cooperative “Zhigansk” of the Zhigansky district. Experiments were laid after cleaning the herds of animals with brucellosis. Total in experience was taken 5 herds created from the herds of young deer immunized at the age of 6 months by the vaccine from strains B.abortus 19 and 82. After immunization periodically were conducted serological studies in BPO, RA and RAC. The results of the production test of the vaccine from strain 82 showed that the best results were obtained from the herd № 5 and № 3. The greatest number of positively reacting deer during all periods of studies was found in the herd № 4 with the greatest defeat before vaccination. However, more sensitive to the vaccine from strain 82 were calves at the age of 6–8 months. Thus, studies show that weakly agglutinable vaccine from strain B.abortus 82 in high and low doses causes in reindeer the formation of immunity capable of protecting vaccinated animals from infection with brucellosis. The number of these calves was less than herds № 5 and № 3 (1–2 %) and more in the herd № 4 (5–7 %). Here, too, there is a direct dependence on the degree of infestation complications deer before vaccination. Revaccination adult deer was transferred to a more relaxed, even though such changes also took place (stiffness, swelling, lameness, and others). In general, those and other, these symptoms disappeared mostly after 2–3 weeks after immunization. Thus, this vaccine having a high reactogenicity causes to the part of the immunized deer postvaccinal complications.
