Study Arms:
- HSCT patients / TBE virus vaccine (Type: ACTIVE_COMPARATOR): Study population: patients who had undergone an allogeneic HSCT 11 to 13 months ago Eligible patients will receive at least two TBE vaccinations (study visit 1 - day 0, study visit 2 -1month after the first vaccination) with a total of two doses of the TBE vaccine FSME-IMMUN®. Whenever possible, the patients will receive complete primary vaccination with a third dose of TBE vaccine (study visit 9 - 9 to 12 months after the first vaccination).
- healthy volunteers / TBE virus vaccine (Type: ACTIVE_COMPARATOR): Clinical healthy volunteers will receive at least two TBE vaccinations (study visit 1 - day 0, study visit 2 -1month after the first vaccination) with a total of two doses of the TBE vaccine FSME IMMUN®. Whenever possible, the volunteers will receive complete primary vaccination with a third dose of TBE vaccine FSME IMMUN® (study visit 9 - 12 months after the first vaccination).

Based on this trial design, predict the completion outcome and termination type (if applicable).
