Pfizer CEO says third Covid vaccine dose likely needed within 12 months
Pfizer CEO Albert Bourla said people will “likely” need a booster dose of a Covid-19 vaccine within 12 months of getting fully vaccinated. His comments were made public Thursday but were taped April 1.
Bourla said it’s possible people will need to get vaccinated against the coronavirus annually.
“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 told CNBC’s Bertha Coombs during an event with CVS Health.

Earlier Thursday, the Biden administration’s Covid response chief science officer, David Kessler, said Americans should expect to receive booster shots to protect against coronavirus variants.
Kessler told U.S. lawmakers that currently authorized vaccines are highly protective but noted new variants could “challenge” the effectiveness of the shots.
“We don’t know everything at this moment,” he told the House Select Subcommittee on the Coronavirus Crisis.
“We are studying the durability of the antibody response,” he said. “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.”
In February, Pfizer and BioNTech said they were testing a third dose of their Covid-19 vaccine to better understand the immune response against new variants of the virus.
Late last month, the National Institutes of Health started testing a new Covid vaccine from Moderna in addition to the one it already has, designed to protect against a problematic variant first found in South Africa.
Moderna CEO Stephane Bancel told CNBC on Wednesday that the company hopes to have a booster shot for its two-dose vaccine available in the fall.
