Who is vaccinated?
Click any country to see the share of its one-year-olds immunised against diphtheria, tetanus and whooping cough (DTP) — and how that's changed over time.
DTP3 = three doses of the diphtheria-tetanus-pertussis vaccine, the standard measure of routine childhood immunisation. Global average is population-weighted across reporting countries.
Overview
About 89% of the world's one-year-olds get the three-dose DTP vaccine — the standard measure of routine childhood immunisation. This map shows coverage for every country.
Key facts
- Global DTP3 coverage is about 89% (population-weighted).
- Sudan currently has the lowest coverage, near 39%, after conflict disrupted its health system.
- Around 110 countries reach 90% coverage or higher.
- DTP3 protects against diphtheria, tetanus and whooping cough; data is from the WHO/UNICEF estimates, current to 2024.
Common questions
What is DTP3 coverage?
The share of one-year-olds who have received three doses of the vaccine against diphtheria, tetanus and pertussis (whooping cough). It is the standard global indicator of routine childhood immunisation.
Which country has the lowest vaccination rate?
Among reporting countries, Sudan is currently lowest at about 39%, following major disruption to its health services.
Why DTP3 rather than another vaccine?
DTP3 requires a child to complete a three-dose course, so it is a good proxy for whether routine immunisation is reaching children fully.
Where does the data come from?
WHO/UNICEF Estimates of National Immunization Coverage (WUENIC), compiled via Our World in Data.
Sources & methodology
Data from WHO/UNICEF (WUENIC), compiled via Our World in Data. The global average is population-weighted across the countries that report this measure; countries without reliable recent data are shown as “no data”.
