How many injections are required for tick‑borne encephalitis? - briefly

How many injections are required for tick‑borne encephalitis? - in detail

The vaccination schedule for tick‑borne encephalitis consists of an initial series followed by periodic boosters.

Adults and adolescents (≥15 years): two doses administered 1–3 months apart. A booster is recommended every 3 years, or every 5 years for those at lower risk.

Children (1–14 years): three doses are required. The first two are given 1–2 months apart, the third dose follows 9–12 months after the second. After completion, boosters are given every 3 years.

Special populations (immunocompromised, travelers to high‑incidence areas): a third dose may be added to the adult schedule, with boosters every 3 years regardless of age.

Vaccine brands (e.g., FSME‑IMMUN, Encepur) follow the same interval recommendations, though some manufacturers list a 30‑day minimum between the first two injections. Compliance with the timing ensures optimal antibody response and long‑term protection.
