Dr. Kate O’Brien is the Director of the Immunization, Vaccines and Biologicals (IVB) Department at the World Health Organization (WHO). In this role she is responsible for leading WHO’s vaccine and immunization strategy and implementation to advance the vision of a world where everyone, everywhere, at every age, fully benefits from vaccines for good health and wellbeing.  The Department works across all levels of WHO (countries, regions, and headquarters), in collaboration with partners, to support countries achieve the optimum use and impact of vaccines across the life-course from infancy to older adult years, in routine programmes, as well as outbreak, emergency and pandemic responses.  Dr. O’Brien served as WHO’s technical lead on COVID vaccine during the pandemic response, through the vaccine pillar (i.e., COVAX) of the global multi-partner pandemic collaboration, ACT-A (Access to COVID-19 Tools Accelerator).

WHO's IVB Department works end-to-end across the vaccine preventable disease (VPD) value chain to achieve life-saving impact.  The Department is responsible for convening and coordinating key global vaccine agendas, VPD control/elimination strategies, and partnerships, as well as developing and issuing global vaccine and immunization policy recommendations, global immunization coverage monitoring, vaccine impact modeling, vaccine preventable disease surveillance, and advancing global vaccine access. IVB also has responsibilities for accelerating the vaccine research and development agenda on priority pathogens, optimizing immunization data systems and monitoring, enhancing immunization programme and campaign effectiveness, along with guiding vaccine introductions, vaccine portfolio prioritization and optimization, and outbreak responses.   

Dr O’Brien is a pediatrician, infectious disease specialist, epidemiologist, and vaccine clinical trialist. She earned a Bachelor of Science in chemistry from University of Toronto (Canada), her MDCM from McGill University (Canada), and her MPH from Johns Hopkins Bloomberg School of Public Health (USA).
