Beyond Coverage: How Timeliness Can Transform Childhood Vaccination Programmes
This commentary from The Lancet Global Health highlights the significant advancements achieved since the establishment of the World Health Organization's Expanded Programme on Immunization (EPI) in 1974. Between 1980 and 2023, coverage rates for original EPI vaccines, including BCG, diphtheria, tetanus, pertussis (DTP), oral polio, and measles, nearly doubled globally. By 2024, the third dose of the DTP vaccine (DTP3), which serves as a standard benchmark for immunization system performance, was administered to 85% of infants worldwide. Similarly, coverage for the first dose of the measles-containing vaccine (MCV1) reached 84% in the same year. While these statistics demonstrate substantial progress in global health infrastructure, the article argues that focusing solely on coverage metrics is insufficient. It suggests that integrating timeliness into the evaluation framework could further transform routine childhood vaccination programmes, ensuring that children receive vaccines at the optimal age for maximum protection. This shift in perspective aims to address gaps in current immunization strategies and improve overall public health outcomes by emphasizing not just whether children are vaccinated, but when they receive these critical interventions.
