Tick-borne encephalitis
Vaccination offers the most effective protection
against tick-borne encephalitis (TBE). Several inactivated TBE vaccines have
received national regulatory approval. FSME-IMMUN (marketed as TICOVAC in the
United States) and Encepur are licensed in multiple European countries, with
FSME-IMMUN/TICOVAC also approved in the United States. Three additional
vaccines—TBE-Moscow, EnceVir and Klesch-E-Vac—are licensed in the Russian
Federation, while SenTaiBao is licensed in China. None of these vaccines are
WHO prequalified. The vaccines have demonstrated immunogenicity and generally
favourable safety profiles, although the extent of clinical safety and
effectiveness evidence varies between products.
In highly endemic areas, WHO recommends
vaccination for all eligible age groups, including children from 1 year of age,
depending on the vaccine used. In areas of moderate or low endemicity,
vaccination should target individuals at increased risk of exposure.
Ticks can also transmit Borrelia bacteria,
which cause Lyme borreliosis. TBE vaccination does not protect against Lyme
borreliosis, which can be treated with appropriate antibiotics. Measures to
prevent tick bites remain important, even among vaccinated individuals.
