One in ten infants miss basic vaccines
DTP3 coverage is a proxy for routine immunization systems worldwide.
DTP3 — three doses of the vaccine against diphtheria, tetanus and pertussis — is the standard test of whether routine immunization reaches a child at all. Of the roughly 140 million infants born each year, 84% complete the course and 16% miss it. Inside that gap are 13.5 million 'zero-dose' children who received no vaccines at all in 2025 — a marker of where access to health services is failing.

Context
The gaps are heavily concentrated: about 53% of the world's nearly 20 million un- and under-vaccinated children live in just ten countries — Afghanistan, Angola, the Democratic Republic of the Congo, Ethiopia, India, Indonesia, Nigeria, Pakistan, the Philippines and Yemen.
Coverage held steady compared with 2024, but progress toward the Immunization Agenda 2030 targets remains off track, and low-income countries lag well behind the global average.
Measles serves as an early-warning system for these immunity gaps because it spreads so easily: nearly 21 million children missed their first measles dose in 2025, up from 19 million in 2019.
