[Active immunization against tick-born encephalitis (TBE) among border guards (1993-2002)].

Our experiences concerning of the vaccination program, started in 1993 and still continued, against tick-borne encephalitis in servicemen of Polish Border Guard are presented. In 1993-FSME IMMUN inject vaccine against TBE has been applied: 50 Border Guard servicemen from Białystok region were vaccinated. In 1994 another group of 1035 officers from 5 Border Guard Squadrons in endemic regions was vaccinated. From 1996 also was vaccinate Border Guard servicemen working with tracing dog. During the period 1993-2001 years 6846 persons were vaccinated. Only one case of mild Adverse Events Following Immunisation (AEFI) was noted (transient headache). Two TBE vaccines were used: "FSME IMMUN" Baxter and "Encepur" Chiron/Behring vaccines. There have been recognized any case of TBE among the vaccinating Border Guard Officers. Nevertheless (in a contemporary epidemiological situation of TBE in Poland) almost all the Border Guard servicemen are endangered with the o/m infection. In this condition active immunization program is in progress.
