Travelers visiting regions where yellow fever is endemic, healthcare workers in endemic areas, and individuals residing in or near outbreak-prone areas are among those who may receive this vaccine. The vaccine is a crucial tool in public health efforts to prevent the spread of yellow fever and is administered to reduce the risk of infection in at-risk populations.
