Summary

In this keynote address at the ‘Health Effects of Vaccines: From Genomics to Policy’ conference, Naor Bar-Zeev, a WHO official and vaccine epidemiologist, discusses the current state of global immunization and the challenges facing the field of vaccine non-specific effects (NSEs). He begins by reflecting on scientific paradigms, using the story of Semmelweis to illustrate resistance to new ideas. He then paints a stark picture of declining immunization coverage, rising measles and diphtheria outbreaks, and the impact of funding cuts on WHO’s capacity. He acknowledges historical tensions between the NSE research community and WHO but emphasizes a new openness to considering NSEs in policy. He outlines a pathway forward, stressing the need for rigorous, policy-relevant research, a priori methodological agreements, and collaborative decision-making. He calls for a balance between reductionist and systems thinking, and for careful communication to avoid polarization. The talk concludes with a call for unity in addressing global health threats.
