On Wednesday, President Joe Biden told CNN's Don Lemon during a CNN Townhall that he expects Covid-19 vaccines could get full approval "quickly." "They're not promising me any specific date, but my expectation, talking to the group of scientists we put together... plus others in the field, is that sometime, maybe in the beginning of the school year, at the end of August, beginning September, October, they'll get a final approval," Biden said.
