Summary
Active immunization is the sole reliable method for preventing tick-borne encephalitis (TBE). Booster doses may not be needed as frequently, as protection lasts longer than previously thought.
Area of Science:
- Immunology
- Vaccinology
- Epidemiology
Context:
- Tick-borne encephalitis (TBE) is a significant public health concern in endemic regions.
- Active immunization is the primary strategy for TBE prevention.
- Current TBE vaccination guidelines recommend frequent booster doses.
Purpose:
- To evaluate the duration of protection conferred by TBE vaccines.
- To assess the necessity of current booster dose schedules.
- To explore alternatives to routine booster administration.
Summary:
- TBE vaccination demonstrates high effectiveness (>95%), though breakthrough infections can occur.
- Recent data indicate TBE vaccine-induced immunity persists for at least 8 years post-immunization.
- This challenges the standard 3-year booster interval, suggesting prolonged protection.
Impact:
- Re-evaluation of TBE booster vaccination schedules is warranted.
- Measuring serum anti-TBE IgG titres can guide individual booster decisions.
- This approach offers an alternative to "blind" booster administration, optimizing TBE prevention strategies.
