Global Measles Outbreaks Surge: UN Warns 30 Million Children Are Unprotected

Even though global immunization efforts have led to an 88% drop in measles deaths between 2000 and 2024 and saved nearly a million lives, 59 countries are reporting large or disruptive measles outbreaks in 2024, a near-tripling of the number seen in 2021. This surge is pushing cases even into nations that had previously eliminated the disease. The World Health Organization (WHO) has issued a dire warning as global measles cases surge, with the highly contagious virus exploiting severe gaps in childhood immunization that emerged during the COVID-19 pandemic. 

The primary factor driving the resurgence is the vast immunity gap among children. WHO data shows that only 84% of children globally received the first dose of the measles vaccine last year, and a crucial 76% received the second dose. This significant shortfall has left as many as 30 million children under-protected, three-quarters of whom are concentrated in conflict-affected or mobile communities in Africa and the Eastern Mediterranean.

According to the health experts, two vaccine doses provide 95% protection, and no child needs to suffer the consequences of this preventable disease. In response, global partners have launched the "Big Catch-Up" campaign, an extended effort continuing through 2025 aimed at reversing pandemic-era declines and strengthening health systems. The WHO is calling for renewed political commitment to enhance surveillance and accelerate outbreak response to finally ensure every child, everywhere, is fully immunized against Measles.
