Nigeria: 93% of diphtheria-affected children under-vaccinated, official says

A Nigerian health official reports that 93% of children affected by diphtheria outbreaks were not fully vaccinated, with many receiving no or only one of three recommended doses. This highlights a significant immunization gap, likely driven by access and coverage failures. The claim is attributed to an official source and is consistent with known vaccination challenges in the region, but independent verification is pending.
