Pfizer is also hoping to make a vaccine that will protect against all variants. "If we are able to achieve that, then I think it is very easy to follow and remember so that we can go back to really the way (we) used to live," th CEO told CBS on Sunday.
"Many variants are coming, and Omicron was the first one that was able to evade -- in a skillful way -- the immune protection that we're giving," Bourla told CBS' "Face the Nation."
"The protection we are getting from the third (dose) it is good enough -- actually quite good for hospitalizations and deaths," Bourla said.
