Tick-borne Encephalitis in Professionally Exposed Persons after Complete Primary Vaccination

In this paper we present a case report of tick-borne encephalitis (TBE) in a professionally exposed person (forestry worker) who acquired this infection three years after he had received a complete primary vaccination. The patient reported multiple tick bites, the last one eighteen days prior to disease onset. The TBE diagnosis was confirmed according to the European Center for Disease Prevention and Control case definition of TBE by clinical criteria (meningitis), epidemiological link (exposure to tick bites in an endemic area) and laboratory criteria (detection of TBEV specific IgM and IgG antibodies in CSF and serum samples). The case presented indicates the need of awareness of possible TBE even in persons who have received complete vaccination, especially in the professionally exposed ones or those exposed to multiple tick bites.
