WHO's Big Catch-Up Hits 100 Million Vaccine Milestone
24 Apr
Summary
- Over 100 million vaccine doses delivered to children worldwide.
- Initiative focused on zero-dose children and those missing vaccines.
- Reached 18.3 million children aged 1-5 in 36 countries since 2023.
The World Health Organization's "The Big Catch-Up" initiative has achieved a significant milestone, administering over 100 million vaccine doses to children worldwide. This global immunization recovery drive was launched in 2023 to counteract disruptions caused by the COVID-19 pandemic, which had led to a decline in routine vaccinations.
The initiative specifically targeted "zero-dose" children, those who have never received any vaccine, and millions more who missed essential immunizations. Between 2023 and early 2026, the program aimed to reach 18.3 million children aged one to five across 36 countries.
This effort is crucial because the pandemic triggered a significant backslide in immunization coverage, increasing the risk of outbreaks for diseases like measles and polio. By strengthening routine immunization systems and engaging communities, The Big Catch-Up aims to protect vulnerable populations and prevent wider disease spread.
While this catch-up campaign has been historic, experts emphasize that sustained investment in robust routine immunization systems remains essential. Millions of children still require vaccination, particularly in conflict-affected areas, highlighting the ongoing need for global commitment to child health.
