  • Have already been administered a third TBE vaccination elsewhere after the two vaccinations in Baxter study 199
  • Have had an allergic reaction to one of the components of the vaccine since the last vaccination in Baxter study 199
  • Suffer from a disease (e.g. autoimmune disease) or are undergoing a form of treatment (e.g. systemic corticosteroids, chemotherapeutics) that can be expected to influence immunological functions
