[FSME monitoring: monitoring of adverse events of tick-borne-encephalitis vaccines by selected paediatricians and general practitioners].

The Institute for Vaccine-Safety of the Austrian Green Cross, the so-called "Institut für Impfsicherheit des Osterreichischen Grünen Kreuzes", promoted a postmarketing sentinel study referring to the safety of tick-borne-encephalitis vaccines in spring 2002. Five-hundred selected paediatricians and general practitioners took part and generated data on 25,905 administered doses. They reported on 107/25,907 (0.413 %) local and systemic adverse reactions. The leading side-effect was fever, besides other adverse reactions corresponding to those known in the literature. The age-group most often affected was that of toddlers and infants. Monitoring with the help of selected paediatricians and general practitioners, carried out alongside the routine obligatory procedures of monitoring, proved to be a valid instrument for detecting vaccine adverse events of tick-borne-encephalitis vaccines.
