Clinical Trial: Humoral Response to Tick-borne Encephalitis Vaccine in Elderly

Study Type: Interventional




Official Title: Humoral Response to TBE Vaccine in Elderly (50+ Year Olds) After Changed Dosage Intervals/Number of Doses?

Brief Summary: Antibody titers after tick-borne encephalitis (TBE) vaccination are less in elderly and vaccination breakthroughs are more common in this age group. This has prompted Swedish authorities to recommend an additional dose in the initial vaccination schedule (= 0+30+90 days instead of the usually recommended 0+30 days. The investigators intend to evaluate this regime.
