In 2020, the World Health Assembly endorsed the Immunization Agenda 2030 (IA2030), the 2021-2030 global strategy for a world in which everyone, everywhere, at every age fully benefits from vaccines. This report reviews trends in WHO and United Nations Children's Fund (UNICEF) estimates of global, regional and national immunization coverage up to 2022 and documents progress in improving coverage to reduce the number of children who have not received the first dose of a diphtheria-tetanus-pertussis-containing vaccine (DTPcvl) (zero-dose children) worldwide by 50% and to increase coverage with 3 DTPcv doses (DTPcv3). Worldwide, coverage with [greater than or equal to]1 dose DTPcvl increased from 86% in 2021 to 89% in 2022, remaining below the 90% coverage achieved in 2019. Estimated DTPcv3 coverage increased from 81% in 2021 to 84% in 2022 but also remained below the 2019 coverage of 86%. Worldwide in 2022, 14.3 million children were not vaccinated with DTPcv1, a 21% decrease from 18.1 million in 2021 but an 11% increase from 12.9 million in 2019. Most children (84%) who did not receive DTPcv1 in 2022 lived in low- and lower-middle-income countries. Global immunization rates recovered from the reduced levels associated with the coronavirus disease 2019 (COVID-19) pandemic in 2022, but progress was unevenly distributed, especially in low-income countries. Urgent action is needed to provide incompletely vaccinated children with catch-up vaccinations that were missed during the pandemic, restore national vaccination coverage to pre-pandemic levels, strengthen immunization programmes to build resilience to future unforeseen public health events, and further improve coverage to protect children from vaccine-preventable diseases.
