In 2025, about 90% of infants worldwide—nearly 116 million—received at least one dose of the diphtheria, tetanus, and pertussis (DTP) vaccine, a one percentage point increase from 2024, according to WHO-UNICEF Estimates of National Immunization Coverage data.
Despite this gain, completion of the full three-dose DTP series reached 85% of infants, still one point below 2019 coverage and reflecting a plateau in progress since 2009.
The data show an estimated 13.5 million “zero-dose” children who received no vaccines in their first year of life in 2025, about 750,000 fewer than in 2024. However, more children started but did not finish vaccination schedules, many in countries supported by Gavi, the Vaccine Alliance.
Measles vaccine coverage was also insufficient, with 84% of children receiving the first dose and 77% receiving the second. Both figures are well below the 95% needed to prevent outbreaks. In 2025, 57 countries reported significant measles outbreaks.
Coverage varied by region. The Americas and South-East Asia fully recovered and surpassed their 2019 levels, with South-East Asia now leading globally. Africa, the Eastern Mediterranean, and Europe improved but remain below pre-pandemic rates. The Western Pacific region saw a decline, placing it furthest below its 2019 coverage figures.
