Yellow fever vaccine is used to prevent infection by the yellow fever virus. This vaccine works by causing your body to produce its own protection (antibodies) against the virus. Vaccination against yellow fever is recommended for all persons 9 months of age and older who are traveling to or living in areas of Africa, South America, or other countries where there is yellow fever infection and for people who are traveling to countries that require yellow fever immunization (certificate of vaccination). It is also needed by other people who might come into contact with the yellow fever virus. Pregnant women should be vaccinated only if they must travel to areas where there is an epidemic of yellow fever and they cannot be protected from mosquito bites. The certificate of vaccination for yellow fever is valid for 10 years beginning 10 days after the first vaccination, or on the date of the second vaccination if within 10 years of the first injection.
