Global Immunization & Vaccine CoverageDTP3, measles (1st dose), HepB3 & tetanus protection — for the world, income groups, regions & ~63 large or high-risk countries · the post-2019 dip and partial recovery · the ~95% measles herd-immunity line

How to read this. Each figure is a WHO/UNICEF coverage estimate reported through the World Bank for a specific year — always shown next to the number, because the latest available year varies by country. This is descriptive: it shows where coverage stands and how it has moved since 2000, including the dip around 2020–2021 and the partial recovery since. It does not predict future outbreaks. The ~95% reference line for measles is the commonly cited two-dose herd-immunity threshold; coverage below it is shown as interpretive resurgence-risk framing, not a forecast.

▤ Coverage leaderboard — lowest coverage / highest risk at top measuredinterpretive

—

Sorted lowest coverage first — the countries where the largest share of children are unprotected, and where (for measles) the gap to the ~95% herd-immunity line is widest. Ranked across the ~63 large or high-burden countries in this atlas (not all 200+ World Bank economies). The year column is the latest available reported value for each country and indicator, which can differ between rows. The "under-immunized" column = 100% − coverage; with no clean zero-dose (no-DTP1) indicator in this API, that gap is the best available proxy for the under-protected share and is interpretive.

◑ The coverage gap — by income group & region measured

—

World Bank aggregate series. Income groups (high / upper-middle / lower-middle / low) and regions are the Bank's own classifications. The spark line traces 2000→latest; "change" is latest vs. 2000. These aggregates are population-weighted estimates, not a simple average of member countries. Tetanus protection is not published at the world aggregate, so it is shown by income/region only.
