Eligibility Criteria

Inclusion Criteria

  • Male and female subjects who:
  • received 2 vaccinations with FSME-IMMUN 0.5 ml during Study 225
  • understand the nature of the study, agree to its provisions and provide written informed consent
  • are clinically healthy (i.e. the physician would have no reservation vaccinating with FSME-IMMUN 0.5 ml outside the scope of the clinical trial)
  • have a negative pregnancy test result at the first medical examination (if female and capable of bearing children)
  • agree to employ adequate birth control measures for the duration of the study (if female and capable of bearing children)
  • agree to keep a Subject Diary

Exclusion Criteria

  • Subjects who:
  • have already been administered a third TBE vaccination elsewhere since receiving two vaccinations in Study 225
  • have a history of infection with, or vaccination against, other flaviviruses since participation in Study 225 (e.g. yellow fever, dengue fever, japanese B encephalitis)
  • have had an allergic reaction to one of the components of the vaccine since participation in Study 225
  • suffer from a disease (e.g. autoimmune disease, immunodeficiency) or are undergoing a form of treatment (e.g., systemic corticosteroids) that can be expected to influence immunological functions
  • have a known or suspected problem with drug or alcohol abuse (\>4 liters wine/week or equivalent doses of other alcoholic beverages)
  • have donated blood or plasma within 30 days of study entry
  • have received a blood transfusion or immunoglobulins within 30 days of study entry
  • are known to be HIV positive (an HIV test is not required specifically for this study)
