A virus transmitted through a tick bite can cause the tick-borne encephalitis – a meningoencephalitis – which often leaves behind remaining damages.
The geographic range of ticks carrying this virus is steadily increasing. Originally endemic to parts of South Germany, Austria und Switzerland, by now the virus can be found in all states in Eastern Europe and South Sweden. In Germany it has reached Central German Uplands (Mittelgebirge).
The vaccination consists of 3 injections at an interval of 0, 7 and 21 or 28 days. The protection lasts at least 3 years and is in effect already 1 week after terminating the initial immunization. A singular vaccination renewal can prolong it for another 3 to 4 years.
