Arena Bioworks shutdown explained

On a jam-packed show, your co-hosts, minus the vacationing Allison DeAngelis, chat with STAT’s D.C. correspondent Lizzy Lawrence about a slow-boiling feud between Vinay Prasad, the head of the FDA’s biologics and vaccine branch, and his staff that has triggered even more exits and plunging morale.

On the drug side of the agency, we dish on the shocking exit of director George Tidmarsh after he was accused of using his regulatory position to exact personal revenge against a former business partner. Bonus: Prasad and Tidmarsh hate each other.
