Global Childhood Immunization: Progress Amidst Conflict and Challenges (2026)

Childhood immunization rates have seen a slight improvement in 2025, with 90% of infants globally receiving at least one dose of the DTP vaccine and 85% completing the full three-dose series. However, this progress is overshadowed by the persistent challenges that continue to hinder global vaccination efforts. The data reveals a stark contrast between regions, with some making significant strides while others are stagnating or even regressing. In my opinion, this highlights the urgent need for targeted interventions in conflict-affected and fragile settings, where immunization programs are often strained by political upheaval, insecurity, and chronic underfunding. What makes this particularly fascinating is the impact of conflict on vaccination rates. For instance, Syria lost 6 percentage points on DTP1 coverage and 12 points on MCV1 in a single year, while Sudan recorded the largest single-country gain globally, increasing DTP1 coverage by 35 percentage points. This raises a deeper question: how can we effectively reach and retain children in conflict-affected settings, and what role do immunization programs play in building resilience and trust in these communities? In my view, the answer lies in strengthening immunization systems and investing in data and disease surveillance systems to drive and guide high-impact immunization program strengthening efforts. However, the foundations that enabled progress are now under significant strain. The full impact of cuts to international health financing announced over the past two years is not yet reflected in these estimates, but the data systems needed to track that impact and protect against backsliding are themselves showing strain. This is concerning, as weakening investments in data systems will lead to outbreaks and deaths that could have been prevented. Personally, I think that the global Immunization Agenda 2030 (IA2030) goal to ensure vaccines reach everyone, everywhere, at every age, is a noble one, but we must address the underlying challenges that are hindering progress. In my opinion, this requires a multi-faceted approach that includes strengthening immunization in conflict and fragile settings, countering false and misleading health information, increasing and sustaining domestic and global funding for immunization programs and partnerships, and investing in stronger data and disease surveillance systems. From my perspective, the future of childhood immunization depends on our ability to adapt and innovate in the face of these challenges. What this really suggests is that we must continue to invest in immunization programs and partnerships, while also addressing the underlying social, political, and economic factors that impact vaccination rates. In my view, this is the only way to ensure that every child, regardless of their circumstances, has access to the lifegiving protection that vaccines provide.
