Primary vaccine coverage of population by income over time

Updated daily
COVID-19 vaccine doses administered per 100 people


This chart shows the primary vaccine coverage ratio across the World Bank income classification. It is calculated as the number of primary doses administered divided by the total population. Full coverage is achieved at 200 primary doses per 100 people. 

Note that primary doses are the doses administered as per the primary (first) vaccination cycle, which excludes boosters. We distinguish from boosters to be able to compare vaccination progress across countries and country groups during the first round of vaccinations. .

There is one more twist. The vaccine coverage ratio for primary doses represents a new way of assessing global vaccination progress that yields consistent comparisons across countries that are invariant to the mix of vaccines used. The method employed is to convert all primary doses administered into double-dose equivalents. That means that doses belonging to 1-dose protocols are multiplied by 2 whereas doses belonging to 3-dose protocols are multiplied by 2/3. With this adjustment, we achieve 200 as the full coverage milestone for primary vaccinations.
