Yellow fever initiative

Global health partners mobilized this year to contain resurging cases of yellow fever in Africa through a massive vaccination campaign. This is targeted at people at risk in the world's 12 highest-burden countries, all of which are in west Africa. The Yellow Fever Initiative, backed by the GAVI Alliance and WHO, breaks new ground by swiftly immunizing people of all ages at risk for the deadly disease, quickly reducing the potential for outbreaks that could threaten the region, or spread worldwide.
