[Reactions after vaccination against tick-borne encephalitis]
1Krajská hygienická stanice Stredoceského kraje, Praha.
Summary
The first dose of the Austrian tick-borne encephalitis vaccine (FSME-IMMUN) caused side reactions in 18.9% of subjects, with higher rates in children. General reactions like fever were more serious than local ones.
Area of Science:
- Immunology
- Vaccinology
- Public Health
Context:
- Tick-borne encephalitis (TBE) is a significant public health concern in endemic regions.
- FSME-IMMUN is an Austrian vaccine used for TBE prevention.
- Understanding vaccine safety is crucial for public trust and vaccine uptake.
Purpose:
- To evaluate the character and frequency of side-reactions following the initial dose of the FSME-IMMUN vaccine.
- To identify demographic factors, such as age, associated with vaccine side-reactions.
- To differentiate between local and general adverse events.
Summary:
- The study assessed side-reactions in 1898 subjects after the first FSME-IMMUN vaccine dose, with a mean reaction rate of 18.9%.
- Incidence of reactions was statistically higher in children under 14 compared to individuals aged 15 and above.
- While local reactions were minor, general reactions, primarily fever, were noted in 13.3% of subjects, reaching 19.2% in one vaccine batch.
Impact:
- Provides essential safety data for the FSME-IMMUN vaccine, informing healthcare providers and public health officials.
- Highlights the need for age-specific monitoring and potential adjustments in vaccination protocols for pediatric populations.
- Contributes to the broader understanding of vaccine safety profiles and adverse event reporting in vaccinology.
