TBE Antibody Persistence and Booster Vaccination Study in Adults (Follow-up to Study 223)

Encephalitis, Tick-Borne Clinical Trial

Official title:
Open-label Phase IV Study to Investigate the Seropersistence of Tick Borne Encephalitis (TBE) Virus Antibodies After the First Booster and the Response to a Second Booster Vaccination With FSME-IMMUN 0.5ml in Adults (Follow Up to Study 223)

Clinical Trial Summary

The purpose of this study is to assess:

- TBE antibody persistence 24, 34, 46 and 58 months (as applicable) after the first booster TBE vaccination with FSME-IMMUN 0.5ml given in Study 223, by means of ELISA (IMMUNOZYM FSME IgG) and Neutralization test (NT),

- TBE antibody response to a second booster vaccination with FSME-IMMUN 0.5ml in the present study, by means of ELISA and NT,

- Safety of FSME-IMMUN 0.5ml after the second booster vaccination.
