title: [Vaccinations for overseas travelers--new evidence and recommendations].
abstract: Vaccinations are an easy and highly effective way to keep travellers healthy. There are few problems with compliance, as all vaccinations are administered pretravel and many vaccines offer protection rates > 95% after a single dose (e.g. hepatitis A, yellow fever). Vaccination of hepatitis A and diphtheriatetanus are recommended for all developing countries. Polio is still indicated for Asia and Africa. Hepatitis B, if possible in combination with A, is recommended for persons travelling for > 30 days, travellers < 35 years, and for people showing special risk behaviour (e.g. high-risk sports, unprotected sexual intercourse). Depending on destination and kind and duration of travel, further vaccinations have to be considered, e.g.: yellow fever (endemic areas, rule of entry), rabies (trekking, travel in remote areas), typhoid fever (Indian sub-continent), meningococcal meningitis (meningitis belt, pilgrims to Saudi-Arabia), tick-borne encephalitis (endemic areas in Europe and Asia), influenza (persons at special risk of complications), Japanese encephalitis (low standard travel in rural areas of Southeast Asia > 30 days), measles (particularly endemic in Africa). Cholera vaccination is virtually never indicated. Several vaccines can be delivered at the same time.
