This week, Hosts Mark Masselli and Margaret Flinter speak with Dr. Alejandro Cravioto, Chair of SAGE, the international panel of experts making COVID-19 vaccine recommendations to the World Health Organization (WHO). Dr. Cravioto talks about their global team of scientists and the rigorous guidelines governing the approval process for emergency authorization for the Pfizer vaccine – as well as all others in the queue. He also discusses the need to scale up production for global distribution, as well as the need to ensure that vaccines are distributed equitably throughout all countries in the world.
