About this ranking

Percentage of children under one year old who received the third dose of the diphtheria, tetanus toxoid and pertussis vaccine in the year. WHO and UNICEF estimates of national immunization coverage (WUENIC), built from administrative records and household surveys.

WHO and UNICEF check each country's reported coverage against survey results, so values can differ from the national figure. Values are whole percentages. WHO revises these series, past years included, when new national reports or estimates come in, so values can change between retrievals.

Every value in the ranking comes from the same publisher and the same period, so the countries are compared on one definition. Equal values share a rank.
