Pfizer CEO Albert Bourla now says that COVID-19 vaccine recipients may need a booster shot within 12 months of getting immunized and that individuals may need to consider getting a new shot each year.

"A likely scenario is that there will be likely a need for a third dose, somewhere between six and 12 months and then from there, there will be an annual revaccination, but all of that needs to be confirmed. And again, the variants will play a key role," he said.

Bourla made the comments earlier this month at a CVS Health event, but they were made public Thursday.

The Biden administration's COVID-19 response chief echoed a similar sentiment on Thursday.

"We are studying the durability of the antibody response," said David Kessler, Biden's chief science officer. "It seems strong but there is some waning of that and no doubt the variants challenge... they make these vaccines work harder. So I think for planning purposes, planning purposes only, I think we should expect that we may have to boost."

Moderna CEO Stephane Bancel also indicated this week that the company is working on a booster for its own vaccine.
