The data show reported yellow fever vaccination coverage data at the national, regional, and global levels, collected through the WHO/UNICEF Joint Reporting Form on Immunization. The page presents both administrative coverage (as reported by countries) and WHO/UNICEF Estimates of National Immunization Coverage for countries designated at risk for yellow fever. Data are updated continuously as country submissions are received, with national, regional, and global figures formally released each mid-July. The data is also viewable and filterable through an interactive dashboard interface.
