FDA SAYS COVID PILL PAXLOVID CAN BE PRESCRIBED BY PHARMACISTS

The president has begun taking Paxlovid and will isolate at the White House "and will continue to carry out all of his duties fully during that time." 

"He has been in contact with members of the White House staff by phone this morning, and will participate in his planned meetings at the White House this morning via phone and Zoom from the residence," she said. 

"Consistent with White House protocol for positive COVID cases, which goes above and beyond CDC guidance, he will continue to work in isolation until he tests negative," Jean-Pierre continued. "Once he tests negative, he will return to in-person work."
