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.

Over 99%
of measles cases and deaths occur in low- and middle-income countries; all of these could be prevented by vaccination.
Only 11
out of 204 countries and territories reached at least 90% coverage for 9 major vaccines in 2019.
17 million
children missed routine vaccinations in 2020 due to the COVID-19 pandemic.
236,000
deaths in 2019 were caused by meningitis, a vaccine-preventable disease.

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