Two kinds of number live on this page. Coverage is the share of the target cohort vaccinated, as estimated by WHO and UNICEF each July from the country's reports, surveys and other evidence, shown beside what the country itself reported. Reported cases are what the national surveillance system sent to WHO; they are a floor, not a count of infections. Every row carries a grade; hover or focus it for the reason, or read how grades are assigned.

Data and sources

Coverage figures are WHO/UNICEF estimates unless a row says otherwise; reported cases are what national authorities sent to WHO and undercount true infections. Each series carries a data-quality grade that says why.
