[Passive immunological prevention of hepatitis B in health service personnel]

40 employees of health service, who by accident cut themselves while doing professional activities and could get infected with HBV, were subject to the trial. They were given 2 ml (approx. 1,000 I.U.) of anti-HBs serum i.m., what prevented infection. Markers of HBV infection were determined in the exposed health service employees as well as in those patients who themselves could possibly cause the infection.
