The Antigen podcast goes behind the science of vaccines. We examine basic science principles, review vaccine history, explore the many facets of their global impact (including COVID-19), and the public sentiment about vaccines around the world.

Season 1 is an eight-part audio-documentary style podcast about the scientific, cultural, and political elements of vaccination. Hear from leading experts about the past, present, and future of this important innovation, as well as people whose families have been impacted by vaccine-preventable diseases.

Season 2 focuses on COVID-19, connecting with experts to give accurate information and updates on the global response to the pandemic. Over the course of the four-part mini-series, we look back at past global health emergencies, discuss efforts across the industry to research potential coronavirus vaccines and treatments, and look ahead to life after a crisis.

Season 3 returns with a three-part mini-series spotlighting maternal immunization. When it comes to vaccine development, there is a shifting paradigm – help protect pregnant women and their infants through research rather than from research. Join expert guests as they discuss the history, the challenges, the innovations, and the potentially exciting developments to come.
