Many health leaders are highly analytical, adaptive learners who thrive on solving complex problems in dynamic, real-world contexts. Their expertise is grounded in years of field experience, where they have honed their ability to rapidly generate insights, test ideas, and innovate solutions in collaboration with diverse stakeholders. In January 2021, as countries were beginning to introduce new COVID-19 vaccines, Kate O’Brien, who leads WHO’s immunization efforts, connected global learning to local action: “For COVID-19 vaccines […] there are just too many lessons that are being learned, especially according to different vaccine platforms, different communities of prioritization that need to be vaccinated. So [everyone] has got to be able to scale, has got to be able to deal with complexity, has got to be able to do personal, local innovation to actually overcome the challenges.” In an Insights Live session with the Geneva Learning Foundation in 2022, she made a compelling …
50 years of the Expanded Programme on Immunization
In two articles published during the fiftieth year of the World Health Organization’s Expanded Programme on Immunization (EPI), Samarasekera and Shattock provide valuable insights into EPI’s remarkable impact on reducing childhood mortality and morbidity since its launch in 1974. Shattock et al. present a detailed quantitative analysis of the lives saved and health gains attributed to vaccination. They estimate that “since 1974, vaccination has averted 154 million deaths, including 146 million among children younger than 5 years of whom 101 million were infants younger than 1 year.” The authors further emphasize the long-term benefits of vaccination, noting that “for every death averted, 66 years of full health were gained on average, translating to 10.2 billion years of full health gained.” These findings underscore the transformative impact of EPI on global health outcomes. Bill Moss of the International Vaccines Access Center (IVAC) calls this “one of humankind’s greatest achievements”. Inherent uncertainties …
