Today, we'll be talking about the news that Vinay Prasad will join FDA as the next director of the Center for Biologics and Research. We'll talk about his past critiques of the agency, his disagreements with former director Peter Marks, and how is tenure might affect vaccine policy, gene therapies, and rare disease companies. I’ll be joined by our senior editor Zach Brennan, who has known Prasad for years, and reporter Lei Lei Wu.
