Yellow Fever Vaccination

Yellow fever can be prevented by vaccination. Travelers should also take precautions against mosquito bites when in areas with yellow fever transmission. Travelers should get vaccinated for yellow fever before visiting areas where yellow fever is found.

For most travelers, a single dose of yellow fever vaccine provides long-lasting protection, and a booster dose of the vaccine is not needed. However, some travelers may require a booster dose. Talk to your healthcare provider to determine if you may need a dose of yellow fever vaccine or a booster dose before your trip to an area at risk for yellow fever.

In the United States, the vaccine is given only at designated yellow fever vaccination centers. International regulations require proof of yellow fever vaccination for travel to and from certain countries. People who get vaccinated should be given an International Certificate of Vaccination. Also note that the vaccine is to be given at least 10 days before travel to an endemic area
