The recent surge in measles cases in conflict zones is a stark reminder of the devastating impact of war on public health. This crisis, exacerbated by vaccine misinformation and cuts to international aid, underscores the urgent need for global action.
A Growing Health Crisis in Conflict Zones
Measles cases have increased by over 25% in conflict-affected regions, with attacks on healthcare facilities, aid shortages, and misinformation campaigns contributing to this alarming trend. Save the Children's analysis of WHO data reveals a disturbing pattern: in 2025, 18 countries in conflict reported over 74,340 measles cases, a significant jump from the previous year's figure of approximately 57,800.
What makes this particularly fascinating is the disproportionate impact of measles outbreaks in conflict zones. Despite representing only 15% of the global child population, these countries accounted for a staggering 30% of all measles cases in 2025. This statistic highlights the vulnerability of children in war-torn regions and the urgent need for targeted interventions.
The Role of Vaccines and Misinformation
Two doses of the measles vaccine provide an estimated 97% protection against the disease. Yet, progress in immunization rates has stalled or even reversed in many countries, both in conflict and non-conflict zones. This is largely due to aid cuts, vaccine misinformation, and disruptions to health systems and service delivery.
Personally, I find it concerning that misinformation campaigns and long-standing vaccine mistrust are contributing to this crisis. In Nigeria, for example, conflict, disruptions in health services, and disinformation campaigns have led to some of the highest numbers of under-vaccinated children in the world.
A Success Story: Save the Children's Impact
However, there is hope amidst this crisis. Save the Children's community volunteers have made a significant impact in Nigeria. By addressing concerns and explaining how vaccines work, they have successfully convinced parents like Iya Saheed to vaccinate their children. Iya's story is a powerful testament to the importance of community engagement and education in overcoming vaccine hesitancy.
The Way Forward
World Immunization Week, led by the WHO, serves as a reminder of the vital role of vaccines in protecting children's lives. Save the Children's senior health lead, Laura Cardinal, emphasizes the need for urgent and sustained investment in essential health services, particularly in conflict-affected areas.
From my perspective, this crisis highlights the interconnectedness of global health and the importance of international cooperation. We must address the root causes of vaccine hesitancy, invest in health systems, and ensure that children in conflict zones have access to life-saving vaccines. Only then can we hope to curb the spread of measles and other preventable diseases.
