7 Billion Doses: The Man Who Vaccinated the World | Gavi CEO Dr. Seth Berkley

Developing a vaccine is one challenge. Delivering it to billions is another entirely. Dr. Seth Berkley, former CEO of Gavi, joins us to unpack his new book Fair Doses, which discusses the hidden systems, politics, and economics behind global immunization.Gavi’s work has helped deliver over 7 billion vaccine doses and immunize more than 3 billion children, reshaping access across the world’s poorest regions. Dr. Berkley explains why vaccine mistrust has persisted for centuries, and why today’s misinformation environment is uniquely dangerous. He breaks down how Gavi’s alliance model coordinates WHO, UNICEF, and manufacturers to move vaccines across continents. We also go inside COVAX, from vaccine nationalism to the supply-chain barriers that defined COVID-19 distribution. Finally, Dr. Berkley looks ahead to how mRNA, synthetic biology, and AI could transform our response to the pandemics to come.
