Vaccine coverage
Vaccines are a powerful tool for saving lives and improving health, but their power can be diluted by gaps in coverage. We study routine childhood immunizations to understand and address these gaps.

15.6 million
children missed routine vaccinations with three doses of the diphtheria, tetanus, and pertussis vaccine from 2020 to 2023 due to the COVID-19 pandemic.
Over 99%
of measles cases and deaths occur in low- and middle-income countries; all of these could be prevented by vaccination.
Coverage doubled
globally for four major childhood vaccines between 1980 and 2023.

Evaluating Gavi immunization programs
In Bangladesh, Mozambique, Uganda, and Zambia, we collected data and analyzed vaccination programs run by Gavi, the Vaccine Alliance.
Research using our estimates
We encourage other researchers to use our data on vaccines in their own work.
