If Joe Biden is elected in November, he has made clear that his first moments in office would mark a dramatic shift in the nation’s approach to Covid-19. Biden’s first post-election phone call, he has said, would be to Anthony Fauci, requesting that the renowned infectious disease researcher continue his government service. For months, he and his staff have pressed for specific answers about how many coronavirus tests the U.S. could conduct by January, when he’d be sworn in as the 46th president. (Biden’s optimistic target: 100 million per month.) And he has pledged to institute daily pandemic briefings for the American public — conducted by scientists and public health experts, not by politicians.
