Vaccination of nursing staff against hepatitis B proved successful. Seroconversion was achieved in about 96 per cent after only three injections. This population has a high risk of contracting hepatitis B infections. After primary vaccination further injections were given to non-responders and law-responders. In these cases 50 per cent developed protective antibody-titers after a fourth injection. Booster injections often raised the titers to higher levels than did the primary injections.
