The Golden Agers and Tick-borne encephalitis. Conference report and position paper of the International Scientific Working Group on Tick-borne encephalitis

Abstract

The 7th meeting of the ISW TBE had the main topic "Tick-borne encephalitis in the Golden Agers". Data from 14 European countries were presented about incidence and clinical course of Tick borne encephalitis (TBE) in general and especially in the population over 50 years of age. With age immunity is impaired quantitatively and qualitatively, the reactions to vaccinations are generally slower, antibody titres reach lower values and decrease earlier. The incidence of the disease is increasing with age, also the clinical course is more severe, they suffer significantly more sequelae, need a longer rehabilitation and have a higher case fatality. Vaccination as the only efficient protection is needed in endemic areas, considering that mobility has increased very much. For the age group over 50 years regular booster vaccinations according to the recommended vaccination intervals or even shorter intervals are most important.
