[Active and passive immunization against hepatitis B virus infection].

Immune serum globulin and hepatitis B immunoglobulin are used for prevention and prophylaxis in hepatitis B virus infection. These are effective against pre- and postexposure cases. Hepatitis B immunoglobulin is more effective than immune serum globulin. Hepatitis B virus vaccines are prepared from HBsAg and its polypeptides. The vaccines prevent from hepatitis B infection in a high percentage. Antibody response for HBsAg vaccines are about 95 percent. Hemodialysis units personnel and patients, surgeons, dentists, male homosexuals and infants in endemic areas must be vaccinated with HBsAg vaccines.
