[Prophylaxis of viral hepatitis A in troops of the North-Caucasian Military District].

In 1999-2000 the preventative vaccination against virus hepatitis A (HA) was performed in 62 thousands of people serving in the North-Caucasian Military District. We proceeded from the data that even the single injection could provide quick protection, at least for 1 year, in 95% of the cases. After the vaccination the steady distribution of HA incidence level by months among the servicemen and decrease in the incidence indices during the period under review (approximately in 3 times) comparing the previous period were observed. Moreover the indices of HA incidence among the vaccinated were lower in 5-7 times than in the comparative groups.
