Tom's next guest today is Dr. Gigi Gronvall. She’s an immunologist and a Senior Scholar at the Johns Hopkins Center for Health Securityand an Associate Professor in the Department of Environmental Health and Engineering at the Johns Hopkins Bloomberg School of Public Health.

Dr. Gronvall discusses the reasons for the rising COVID infection rates and the urgency of the campaign to persuade unvaccinated Americans to get their shots. She also addresses a technical point raised in the clip we play of a heated exchange between Dr. Fauci and Sen. Rand Paul (R, Ky.) at a Senate hearing yesterday. And the Hopkins scholar notes the growing consensus among epidemiologists and infectious disease experts that the origin of the COVID-19 virus that has killed more than 4 million people in the past 20 months was an infected animal for sale at the Wuhan Seafood Market in Wuhan, China, and not a Chinese medical laboratory.
