When should adults receive their first tick vaccine and what is the schedule? - briefly
Adults should receive the first dose of a tick‑borne disease vaccine shortly before the onset of the tick season, typically in early spring. The regimen includes a second injection 2–4 weeks later, a booster at 12 months, and additional boosters at five‑year intervals.
When should adults receive their first tick vaccine and what is the schedule? - in detail
Adults at risk of tick‑borne encephalitis should begin the primary series as soon as possible after exposure risk is identified. The initial dose is administered on day 0, followed by a second dose 1–3 months later. A third dose is given 5–12 months after the second to complete the basic immunisation.
Booster doses are required to maintain protection. The first booster is recommended 5 years after the third dose, and subsequent boosters are given at 5‑year intervals for the remainder of the individual’s life, provided the risk of exposure persists.
Typical schedule:
- Dose 1: day 0
- Dose 2: 1–3 months after dose 1
- Dose 3: 5–12 months after dose 2
- Booster 1: 5 years after dose 3
- Booster 2 and beyond: every 5 years
Vaccination is advised for adults living in or travelling to endemic areas, occupational exposure (forestry, agriculture, outdoor recreation), or any situation with frequent tick contact. Serological testing before the first dose is not routinely required, but clinicians may assess prior immunisation history to avoid unnecessary repeats.
