President-elect Biden’s transition team unveiled the members of his Covid-19 task force on Monday, a who’s-who of former government health officials, academics, and major figures in medicine. The list includes Rick Bright, the former head of the vaccine-development agency BARDA ousted by the Trump administration in April; Atul Gawande, the surgeon, writer, and recently departed CEO of Haven, the joint JP Morgan Chase-Berkshire Hathaway-Amazon health care venture; and Luciana Borio, a former FDA official and biodefense specialist. … As expected, the board’s three co-chairs are Marcella Nunez-Smith, a Yale physician and researcher; Vivek Murthy, a former U.S. surgeon general; and David Kessler, a former FDA commissioner.
