Brief Summary:
The objective of this study is to investigate the immunogenicity and safety of FSME-IMMUN 0.5 ml in two age strata (stratum A: 16 to 49 years, stratum B: > 50 years), with the first and second vaccinations being administered according to a rapid immunization schedule (12 ± 2 days apart). The third vaccination will be administered approximately 6 months after the first dose.

Study Type : Interventional  (Clinical Trial)
Enrollment : 330 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention

Primary Outcome Measures :
  1. Immunogenicity: Seropositivity rate as determined by Enzyme-Linked Immunosorbent Assay (ELISA) and Neutralization test (NT) at Days 7, 14 and 21 after the second vaccination, in stratum A and B separately, and in the two age strata combined.

  • Have a history of allergic reactions, in particular to one of the components of the vaccine;
  • Suffer from a disease (e.g. autoimmune disease) or are undergoing a form of treatment (e.g. systemic corticosteroids) that can be expected to influence immunological functions;
