When is the third tick vaccine given? - briefly
The third dose of the primary tick‑borne encephalitis vaccination schedule is given several months after the second injection, usually between five and twelve months (commonly around nine months). Subsequent boosters are then administered every three to five years, depending on the specific vaccine used.
When is the third tick vaccine given? - in detail
The third dose of a tick‑borne disease vaccine is administered after the initial two‑dose series has been completed. The standard interval between the first and second injections is 1–3 months, depending on the product used. The third injection follows 5–12 months after the second dose; most guidelines recommend a minimum of 6 months to ensure optimal immune response.
Key points for the final dose:
- Minimum interval: 5 months after the second injection.
- Preferred interval: 6–12 months, aligning with the schedule of the most widely used preparations (Encepur, FSME‑IMMUN).
- Age considerations: Children as young as 1 year may receive the series, with the third dose timed according to the same interval rules.
- Special populations: Immunocompromised patients may be advised to shorten the interval to 5 months, while healthy adults can follow the 6–12 month window.
- Travel planning: For individuals traveling to endemic areas, the third dose should be completed at least 2 weeks before exposure to allow antibody development.
After the third injection, long‑term protection is maintained with booster doses. The first booster is recommended 3 years after the third dose, then every 5 years thereafter, or more frequently for high‑risk groups. Compliance with these intervals maximizes vaccine efficacy against tick‑borne encephalitis and related infections.
