Primary vaccine coverage of population by country

Adjusted COVID-19 vaccine doses administered per 100 people

EXPLAINER

This map shows the primary vaccine coverage ratio for each and every country (the map is clickable and provides additional detail in the tooltips). The vaccine coverage ratio is defined as the total number of doses administered relative to the total population. We focus here on the primary vaccination cycle and exclude boosters.

There is one more twist. The vaccine coverage ratio calculated here 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 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 further details on this method, check out this post and the background note below on double-dose equivalents and other aspects.
