Pfizer booster shot ‘likely’ needed within 1 year, says CEO

During a recently aired interview, Bourla said that patients will "likely" need an additional dose of the vaccine within 12 months of becoming fully vaccinated with the two required doses.

Researchers are still unsure how long the COVID vaccine protects against the virus.

During an event with CVS Health, which was recorded April 1 but released on Thursday, Bourla said it's likely possible people will need to get vaccinated against the coronavirus annually, CNBC reported.

The Pfizer chief said that it is important to suppress the pool of people who are susceptible to the virus.

US President Joe Biden received his second dose of the BioNTech-Pfizer vaccine in January.

According to Pfizer, its vaccine is more than 91 percent effective at protecting against COVID-19, and maintains that effectiveness for more than six months, similar to Moderna.

Bourla also on Thursday defended the price of his company's vaccine, saying the product is saving lives and will not be sold to poor countries for a profit.

Though, the vaccines have not yet been tested in on pregnant women, Dr. Al Khenyab has said that evidence from non-clinical studies of the Pfizer and BioNTech vaccine has been reviewed by the World Health Organization and the regulatory bodies in the USA, Canada and Europe and has raised no concerns about safety in pregnancy.

However, this needs to be confirmed, Bourla said.

"It seems strong but there is some waning of that and no doubt the variants challenge" that, he said.

"So I think for planning purposes, planning purposes only, I think we should expect that we may have to boost".

About 144 volunteers will be given the third dose, mostly those who participated in the vaccine's early-stage United States testing previous year.

The rationale behind the decision was not announced and it comes amid views that all persons who would like to be vaccinated should be offered the shot.
