![]() In 2015, the US Advisory Committee on Immunization Practices published a recommendation that 1 dose of YF vaccine provides long-lasting protection and is adequate for most travelers. Because of changes in YF virus circulation, however, recommendations can change therefore, before departure, travelers and clinicians should check CDC’s destination pages for up-to-date YF vaccine information. CDC recommends YF vaccination for travel to areas classified as having endemic or transitional risk (Maps 5-10 and 5-11). These recommendations are based on a classification system for destination-specific risk for YF virus transmission: endemic, transitional, low potential for exposure, and no risk ( Table 2-08). CDC RecommendationsĬDC’s YF vaccine recommendations are guidance intended to protect travelers from acquiring YF virus infections during international travel. But because entry requirements are subject to change at any time, health care professionals and travelers should refer to the online version of this book and the CDC Travelers’ Health website for any updates before departure. WHO publishes a list of YF vaccine country entry requirements and recommendations for international travelers approximately annually. Unless issued a medical waiver by a yellow fever vaccine provider, travelers must comply with entry requirements for proof of vaccination against YF. The World Health Organization (WHO) defines areas with risk for YF virus transmission as countries or areas where YF virus activity has been reported currently or in the past, and where vectors and animal reservoirs exist. Certain countries require proof of vaccination from travelers arriving from all countries ( Table 5-24) some countries require proof of vaccination only for travelers above a certain age coming from countries with risk for YF virus transmission. Under the IHR, countries are permitted to establish YF vaccine entry requirements to prevent the importation and transmission of YF virus within their boundaries. Yellow Fever Vaccine Entry RequirementsĮntry requirements for proof of YF vaccination under the International Health Regulations (IHR) differ from CDC’s YF vaccination recommendations. Recommendations for prevention of other travel-associated illnesses can also be found on the CDC Travelers’ Health website. Updated information reflecting changes since publication can be found in the online version of this book and on the Centers for Disease Control and Prevention (CDC) Travelers’ Health website. The information in this chapter was accurate at the time of publication however, it is subject to change at any time due to changes in disease transmission or, in the case of YF, changing entry requirements for travelers. Country-specific maps are included to aid in interpreting the information. The following pages present country-specific information on yellow fever (YF) vaccine requirements and recommendations, and malaria transmission information and prevention recommendations.
