Found it, it’s in here:
“Q How many — how many Americans need to be vaccinated for us to go back to normal? Like what is the percentage of total vaccinations that have to be deployed?
THE PRESIDENT: Well, I think — look, I think we get the vast majority — like is going on in so many — some industries and some schools — 96, 97, 98 percent. I think we’re getting awful close. But I’m not the scientist.
I think — but one thing for certain: A quarter of the country can’t go unvaccinated and us not continue to have a problem.”
