Specific, passive prevention of hepatitis B perinatal transmission to infants born to mothers with HBs antigenemia]

The study aimed at evaluating an infectiousness of HBV-positive mothers and mothers with the acute hepatitis B to their progeny in various periods of their lives, and elaborating the effective ways of HBV infection prevention during the first two years of child life as well as evaluating HBIG in prophylaxis. It was found, that prophylaxis should be carried out in children of HBs-positive mothers independent of a routine system. An infection is usually asymptomatic in the first two years of life. It seems, that routinely used prevention methods are insufficient. Three HBIG doses should be given every 4 months. However, the best way to prevent HBV infection is passive-active immunization.
