Travelers to what areas should consider vaccination against tick-borne encephalitis (TBE)?

Tick-borne encephalitis (TBE) is a disease caused by a flavivirus transmitted by tick bite in certain areas of Europe and Asia. It may also be transmitted through the consumption of unpasteurized milk or cheese from infected cows, goats, or sheep. CDC provides details of TBE-endemic areas, but notes that the risk of TBE in endemic areas is variable within risk areas and from year-to-year. Additional geographic information is available from CDC:

Travelers moving or traveling to a TBE-endemic area and likely to have extensive exposure to ticks based on their planned outdoor activities and itinerary should be vaccinated for TBE. TBE vaccination may be considered for other travelers to TBE-endemic areas based on their likely exposure to ticks during their activities, their risk of a poor health outcome, and their personal perception and tolerance of risk.
