[Effectiveness and tolerance of genetically engineered vaccines for hepatitis B--a comparative study].

The two hepatitis B vaccines produced by gene technology that are presently available in Germany, were compared in respect of efficacy and tolerance in 80 nurses (female and male) who were under training. Both vaccines proved to be highly effective and well tolerated. In respect of the achieved anti-HBs titer, however, the two vaccines differed significantly from each other. Using the 20 micrograms HBs antigen, the antibody titers obtained were higher by a factor of 1.8. The article gives update recommendations in respect of hepatitis B vaccination as a preventive measure in risk groups.
