Yellow Fever Travel Information

Yellow fever is a disease caused by a virus that is spread through mosquito bites. Symptoms include fever, chills, headache, backache, and muscle aches. About 15% of people who get yellow fever develop serious illness that can sometimes be fatal. Travelers to certain parts of South America(/travel/yellowbook/2018/infectious-diseases-related-to-travel/yellow-fever#5303) and Africa(/travel/yellowbook/2018/infectious-diseases-related-to-travel/yellow-fever#5302) are at risk for yellow fever. Yellow fever vaccine is the best protection against yellow fever disease.

Yellow Fever Vaccination

Search for Stamaril Clinics


  • Travelers should get yellow fever vaccine at least 10 days before travel.
  • Because US-licensed yellow fever vaccine is out of stock, a limited number of clinics in the United States(/travel/page/search-for-stamaril-clinics) are now offering an equally safe and effective alternate vaccine, Stamaril. The nearest Stamaril clinic may be some distance away and appointments may be limited.
  • Use the map here to find your nearest clinic. Be sure to call and schedule well in advance.

Preventing Yellow Fever

Yellow fever vaccine is the best protection against yellow fever disease. Travelers to areas with risk of yellow fever should also prevent mosquito bites(/travel/page/avoid-bug-bites) by using insect repellent, wearing long-sleeved shirts and pants when outdoors, and sleeping in an air-conditioned or well-screened room or under an insecticide-treated bed net.
