Tick-borne encephalitis is an infection caught from the bite of an infected tick. Ticks occurs in warm, forested parts of central and eastern Europe and Scandinavia, especially where there’s heavy undergrowth, and is more common in late spring and summer. This disease leads to headaches, fever and an inflammation of the brain (encephalitis) and its lining (meningitis) and can lead to brain damage and death. Risks increase with age and the more eastern destinations. Those walking or camping in such areas should wear clothing that covers most of the skin and use insect repellents. The vaccination is highly effective (99%) and consists of 2 vaccines given least 14 days apart (with a third given 5-12 months later ).
