Fauci said: “We know that the effectiveness of the vaccine lasts for at least six months, and it is likely to be much more, but I think we will definitely need a booster shot sometime in a year or so after we get it. The first vaccine.”
On Wednesday, there were more than 33 million cases of Covid-19 in the United States and more than 587,000 deaths.
Fauci also said on Wednesday that reinforcements for the variants may not be necessary.
“Instead of having to play around with every variable and develop a specific variable reinforcer, chances are you can keep amplifying versus the wild type, and you’ll end up with a satisfying answer that you don’t need. Worry about the variables.”
The wild type is the non-mutated strain of the virus.
Burla said Pfizer has not yet completed trials of the booster vaccine.
“I think within a month or two we will have enough data to talk about it with greater scientific certainty,” he said.
The first dose of the Covid-19 vaccine from Pfizer was given in the United States on December 14, 2020 – five months ago.
“If they get the second shot eight months ago, they might need the third shot,” Burla said, adding that the booster shots could come between September and October of this year.
He said Pfizer will have to see what the FDA approves and recommends how best to protect the American people.
