Global Immunization Coverage Report: 2025 Data Summary
The WHO-UNICEF Estimates of National Immunization Coverage (WUENIC) for 2025 reveal modest progress in childhood vaccination rates, but persistent gaps threaten disease prevention globally.
Key Coverage Statistics
DTP Vaccine (Diphtheria, Tetanus, Pertussis):
- First dose coverage: 90% of infants (~116 million children)
- Full three-dose series completion: 85% (~110 million children)
- Improvement: +1 percentage point from 2024, but remains 1 point below 2019 pre-pandemic levels
Measles Vaccine:
- First dose (MCV1): 84% coverage
- Second dose (MCV2): 77% coverage
- Both fall short of the 95% threshold required to prevent outbreaks
- Result: 57 countries reported large or disruptive measles outbreaks in 2025
Critical Gaps
Zero-Dose Children: An estimated 13.5 million infants received no vaccines in their first year (improvement from 14.25 million in 2024). However, approximately 7.3 million children who received their first DTP dose failed to complete the schedule before measles vaccination, representing significant program dropout.
Geographic Disparities:
- 100 countries have maintained ≥90% DTP3 coverage since 2019 with minimal progress in expanding this group
- 65 countries remain stagnant or declining, including 13 fragile, conflict-affected, or vulnerable (FCV) nations
- More than half of zero-dose children live in FCV settings despite these regions representing only one-third of the global child population
- South-East Asia shows strongest recovery; Western Pacific remains furthest below 2019 baseline
Vaccine Hesitancy in High-Income Settings: Even countries with full vaccine access report coverage declines due to shifting political commitment and rising hesitancy (examples: South Africa DTP1 coverage declined 20 points since 2019; Bosnia and Herzegovina saw 23-point drop in MCV1 after 2024 gains).
Contributing Factors
- Conflict and displacement disrupting immunization programs
- Chronic underfunding in low-resource settings
- Misinformation affecting vaccine uptake
- Data system deterioration (only 18 national surveys submitted in 2025 vs. 50 in 2024)
- Reduced international health financing
Positive Examples
Sudan demonstrated significant recovery potential, increasing DTP1 coverage by 35 percentage points and MCV1 coverage by 22 points in a single year despite ongoing conflict—showing what improved access can achieve.
Pharmacist's Note: As a healthcare professional, I emphasize that vaccination schedule completion is critical. Partial immunization leaves children vulnerable to preventable diseases. The measles data is particularly concerning: achieving 95% coverage with two doses is epidemiologically necessary to prevent outbreaks in susceptible populations. Travelers to regions with suboptimal measles coverage should verify their own immunity status (two MMR doses or serologic confirmation) before travel. Healthcare providers should counsel patients on the documented safety profile of routine childhood vaccines and address specific concerns rather than contributing to hesitancy.
Public Health Recommendations
WHO and UNICEF call for:
- Strengthened immunization services in conflict-affected settings
- Counter-messaging against vaccine misinformation
- Increased domestic and global funding for immunization programs
- Investment in disease surveillance and data systems
