Nonetheless, the previous commissioner of the U.S. Meals and Drug Administration careworn that new instances alone shouldn’t be the metric receiving essentially the most focus as extra individuals are vaccinated in opposition to Covid.
“I do not assume we must be eager about reaching herd immunity. I do not know that we ever obtain true herd immunity, the place this virus simply stops circulating,” Gottlieb mentioned on “Closing Bell.” “I believe it is at all times going to flow into at a low degree. That must be the purpose, to maintain the extent of virus down.”
Gottlieb, who serves on the board of Covid vaccine maker Pfizer, mentioned he expects the U.S. to see vital progress towards that purpose within the coming weeks.
