[The vaccinal prophylaxis of hepatitis B in Russia--the achievements, problems and outlook].

Certain specific features of the present epidemic situation with hepatitis B (HB) in Russia were established: significant growth of HB morbidity, starting from 1995; the prevalence of persons aged 15-29 years among HB patients, which was linked with the sharp activation of the sexual route of the transmission of HB virus in recent years; an essential increase in the number of patients having contacted this virus in the process of the intravenous use of drugs. The results of the use of vaccine "Engerix B" among persons belonging to different risk groups were considered (a decrease in HB morbidity among them by 8-19 times was noted), the study demonstrated high immunogenicity anti-HBs antibodies on protective titers were determined in 92.3-95.

In Uzbekistan and Moldova 542 children born of HBsAg carriers were immunized against hepatitis B (with vaccine Engerix B according to the immunization schedule of 4 injections). Anti-HBs antibodies in protective titers were detected by EIA and RIA techniques in 76.7% of children aged 4-5 months after the 3rd injection, in 95.

The presence of great differences in the activity of the epidemic process of hepatitis A (HA) in some regions of Russia is shown and the data necessary for establishing the structure of HA foci in groups of children, as well as the proportion of different forms of the disease registered in such foci (the icteric form in 22.7% of patients, the obliterated form in 11.3% of patients, the nonicteric form in 45.
