Asked by CNN’s Dana Bash on “State of the Union” whether he thinks Americans will still need to wear masks next year, Fauci, the nation’s top infectious disease expert, replied: “You know, I think it is possible that that’s the case and, again, it really depends on what you mean by normality.”
Fauci told Bash that while he can’t predict when the US might return to operating as it did before the pandemic told hold, he thinks that by the end of this year “we’re going to have a significant degree of normality beyond the terrible burden that all of us have been through over the last year.”
“We know for sure that when you give a prime with the Pfizer followed by a boost 21 days later that you get a 94% to 95% efficacy and the difference between the level of antibodies after one dose versus two doses is about tenfold higher,” he said.
“And that is really important because when you have that high a degree comparable to the single dose alone, that’s the cushion that you would like to have when you get a variant that isn’t as well-protected against by the antibodies induced by the vaccine, but you have enough level to be able to prevent at least severe disease.”
