Yellow fever is one of the world's most deadly diseases. If you think it's a disease that can only be found in tropical climates, think again. Even with a single shot vaccine, the risk of outbreaks of yellow fever is significant and growing globally. EYE on Yellow Fever is a ten-part series that takes you inside a concerted global effort to ensure that yellow fever does not become the next big global health threat. EYE on Yellow Fever is a series by the Eliminate Yellow Fever Epidemics (EYE) Strategy, which operates in 40 countries with over 50 partners, including the World Health Organization, Gavi - the Vaccine Alliance, UNICEF, the US Centre for Disease Control and the Bill and Melinda Gates Foundation.
