On Sept. 26, Pfizer CEO and Chairman Albert Bourla predicted life will return to normal within a year, but it's likely annual COVID vaccinations will be necessary.

Bourla's vision for a "return to normal life" would position Pfizer and Moderna to make billions in profits dispensing endless booster doses. How much the manufacturers stand to gain depends on how big the rollout is.

"Within a year I think we will be able to come back to normal life," Bourla said in an interview on ABC's "This Week."

Bourla said he does not think this means variants will no longer exist, or that we "should be able to live our lives without having vaccinations."

The "most likely scenario," Bourla said, is annual vaccination with vaccines that last at least a year, "but we don't know really, we need to wait and see the data."
