Matt Ridley is a former member of the House of Lords, and the author of ten books, including most recently, with Alina Chan, of Viral: The Search For the Origin of Covid-19. In this episode, he discusses why the pandemic may have been caused by a lab leak in Wuhan, China’s efforts to suppress information, how “open-source analysts” helped expose the origins of the virus, vaccine development, and why Covid may eventually “become the common cold.”
