Abstract

A total of 222 adult subjects aged 19-51 years were enrolled in this multi-center, phase III study to evaluate immunogenicity and safety of the first booster immunization with a new tick-borne encephalitis (TBE) vaccine. This was an extension study that followed subjects who had received primary immunization 12-18 months previously with either the new or formerly licensed TBE vaccine according to the rapid immunization schedule (i.e. on Days 0, 7 and 2 1). Compared to the levels of primary immunization, prior to first booster, neutralizing TBE antibodies (geometric mean titers, GMTs) of both vaccination groups had remained on a high level and were far above the detection limit of the neutralization test used. All subjects showed a sharp increase of TBE antibodies following the booster. The booster was well tolerated by the subjects. Conclusion: These results in terms of both immunogenicity and safety indicate that the TBE vaccination with this new TBE vaccine can be used effectively and safely in adults. A long lasting immunity can be concluded from the strong immune response following the first booster. (C) 2003 Elsevier Ltd. All rights reserved.
