CDC Health Information for International Travel

RESOURCES

The CDC’s website (CDC.gov/Travel) is a highly reliable source for current vaccination recommendations and country-specific health information. Information is downloadable in several formats, so travelers can load pertinent resources onto their phones or other electronic devices before they leave. The CDC and CDC Vaccine Schedules apps can also be great resources on the go.

The CDC publishes a biennial guide called CDC Health Information for International Travel, popularly known as the “Yellow Book.” This detailed publication, which offers immunization guidelines and travel health information, is aimed primarily at health care professionals but can be a valuable resource for anyone interested in healthy international travel. The book is available online, as an app or in a print edition.

An abundance of other useful information is available on a variety of platforms. Nonprofit, academic and governmental websites are likely to contain the most reliable information; in the United States such sites have domains ending in .org (for nonprofits such as DAN), .edu (for academic institutions) or .gov (for governmental agencies).
