Yellow Fever

Comprehensive Yellow Fever Vaccination Requirements

Please see the Destinations section for recommendations for specific countries.

Yellow fever is a viral disease found in parts of Africa and South America. It is transmitted to humans by a mosquito bite. Even though there is no risk of becoming infected while traveling in countries outside of tropical South America or sub-Saharan Africa (i.e., Central, East, Southern, and West), certain countries REQUIRE a yellow fever vaccination. Some countries require a Yellow Fever Vaccination for all travelers, while others require only a vaccination if a traveler is coming FROM either areas infected with yellow fever or areas where yellow fever transmission has occurred (called “endemic” areas). The endemic areas are found in tropical South America and Africa. For the current list of yellow fever infected countries, read “Summary of Health Information for International Travel” (the “Blue Sheet”).

In general, if you are traveling only from the United States to countries in Europe (Western or Eastern), North Africa, the Middle East, the Indian subcontinent, East or Southeast Asia, Australia and the South Pacific, the Caribbean, most of Central America, or temperate South America, CDC does not recommend and you are not required to have a yellow fever vaccination.

However, if your travel plans include traveling to or from a South American or African country that is infected with yellow fever or is located in areas where yellow fever transmission has occurred (endemic areas), then the easiest and safest thing to do is to get a yellow fever vaccination and a signed certificate. Be aware, the age requirements for vaccination can vary from country to country. Be sure to read the Yellow Fever Certificate information below, the instructions, and the country-by-country requirements on this page.

Yellow fever vaccination, a 1-dose shot, may be administered to adults and to children over 9 months of age. This vaccine is administered only at designated yellow fever centers, usually your local health department. If at continued risk, a booster is needed every 10 years.

MEDICAL REASONS NOT TO RECEIVE THE VACCINE:

Infants under 4 months must not be immunized.
Persons severely allergic to eggs should not be given the vaccine. Generally, persons able to eat eggs or egg products can safely receive the vaccine.
It is prudent on theoretical grounds to avoid vaccinating pregnant women, and for non-immunized pregnant women to postpone travel to epidemic areas until after delivery. (Pregnant women who must travel to high-risk areas should be vaccinated.)
In general, persons whose immune systems are suppressed (due to HIV infection or other conditions), persons who are undergoing treatments for cancers (e.g., leukemia and lymphoma), or persons being treated with corticosteroids, alkylating drugs, antimetabolites, or radiation should not be vaccinated unless traveling to an area of known yellow fever transmission. (Patients with suppressed immune systems have a theoretical risk of encephalitis due to the yellow fever vaccine virus.)

Yellow Fever Certificate
After immunization, an International Certificate of Vaccination is issued and is valid 10 days after vaccination to meet entry and exit requirements for all countries. The Certificate is good for 10 years. You must take the Certificate with you. Travelers who have a medical reason not to receive the yellow fever vaccine should obtain a medical waiver. Most countries will accept a medical waiver for persons with a medical reason not to receive the vaccine. When required, CDC recommends obtaining written waivers from consular or embassy officials before departure. A physician’s letter clearly stating the medical reason not to receive the vaccine might be acceptable to some governments. It should be written on letterhead stationery and bear the stamp used by a health department or official immunization center to validate the International Certificate of Vaccination. Check embassies or consulates for specific waiver requirements.

INSTRUCTIONS: Listed next to each country are the Yellow Fever recommendation and requirement codes, which are explained at the bottom of the pages. The explanations are listed in order of broadest requirements (those that apply to most travelers) to the narrower requirements (fewer people are likely to be in this category). A dash (–) indicates no vaccination is required or recommended. Age requirements are the 4th column and refer to the age at which vaccination is required: >1y = greater than 1 year; >6m or >9m = greater than 6 or 9 months; >0 = the age requirement is at the country’s discretion, and vaccination could be required as young as birth. If you are traveling with infants and young children, check with embassies and consulates for their specific requirements, and then consult with your doctor.
