The yellow fever vaccine is given in one dose and typically lasts ten years. If you are at continued risk for yellow fever, you should get a booster every ten years. While the vaccine is considered safe, infants, pregnant women, people with weak immune systems, and people with egg allergies cannot be vaccinated. Side effects occur in up to 30 percent of people who receive the vaccine. Common reactions include headache, muscle ache, and low-grade fever starting within the first five to 10 days after vaccination.

It is recommended that all people living in or traveling to countries where yellow fever is known to exist receive the yellow fever vaccine. In addition to Africa and South America, there are other countries where the vaccine is required for entry in order to prevent the spread of the disease. Certain laboratory workers and researchers who work with the yellow fever virus likewise should be vaccinated. The vaccine is available at designated vaccine clinics.
