1Yellow fever vaccine entry requirements are necessary for travelers to comply with in order to enter the country. In general, these are in place to prevent importation and transmission of yellow fever virus. Countries requiring yellow fever vaccination for entry adhere to the regulations put forth by WHO as stated in the International Health Regulations. Some countries require vaccination for travelers coming from an endemic zone. “Traveling from an endemic zone” is defi ned as transit through an endemic zone in the previous 6 days. Country requirements are subject to change at any time; therefore, CDC encourages travelers to check with the appropriate embassy or consulate prior to departure.

3Please note, the U.S. Advisory Committee on Immunization Practices recommends avoiding vaccination of infants.
