How long after is a tick vaccine given? - in detail
The initial injection of a tick‑borne disease vaccine is typically given when the child is between six and eight weeks old, or in adults at least 18 years of age, provided no contraindications exist. A second dose follows after a minimum interval of two weeks and not later than four weeks, establishing primary immunity.
A booster dose is required twelve months after the primary series to maintain protective antibody levels. Subsequent boosters are administered annually, usually in late summer or early autumn, before the tick‑activity season begins.
For travelers to endemic regions, the schedule is adjusted:
- First dose at least two weeks before exposure.
- Second dose 2–4 weeks after the first, completing the primary series.
- Annual booster before each new season of travel to the same area.
Key points for all recipients:
- Minimum interval between first and second injections: 14 days.
- Minimum interval between second injection and first booster: 12 months.
- Booster interval thereafter: 12 months.
- Immunocompromised individuals may require serological testing to confirm adequate response.
Adherence to these intervals ensures optimal protection against tick‑borne infections.
