Summary
Tick-borne encephalitis (TBE) is a serious disease transmitted by infected ticks. Vaccination is highly effective and recommended for individuals spending time in endemic forest areas.
Area of Science:
- Epidemiology
- Vaccinology
Context:
- Tick-borne encephalitis (TBE) is a rare but severe neurological disease endemic in specific regions.
- Acquisition occurs via infected tick bites, with significant potential for severe outcomes including paralysis and fatality.
- No specific antiviral therapy exists for TBE.
Purpose:
- To review the epidemiology of TBE and the efficacy of available vaccination strategies.
- To inform updated public health recommendations regarding TBE prevention in Switzerland.
Summary:
- The TBE vaccine is highly immunogenic, achieving protective antibody levels in 99% of recipients with minimal side effects.
- While mass vaccination is not cost-effective, it is epidemiologically efficient, as demonstrated in Austria.
- Current Swiss recommendations are being liberalized to include active vaccination for all individuals regularly in endemic forest areas.
Impact:
- Updated recommendations aim to increase TBE prevention in at-risk populations, particularly those with occupational or leisure exposure.
- Enhanced vaccine uptake can reduce the incidence of severe neurological sequelae and fatalities associated with TBE.
- This strategy addresses the growing concern of leisure-related TBE infections in endemic zones.
