Global childhood immunization coverage is making slow progress. In 2025, around 116 million infants worldwide received at least one dose of the vaccine against diphtheria, tetanus, and pertussis. The number of children completing the three-dose schedule was approximately 110 million.

These numbers represent a small increase from the previous year, but overall coverage remains below 2019 levels. Further details on global immunization coverage are available from the World Health Organization and UNICEF, which published the estimates.
