Albert Bourla, CEO of Pfizer, said people will “likely” need a booster dose of a Covid-19 vaccine on Thursday within 12 months of being fully vaccinated.

He also said it is possible that people may need to be vaccinated against the virus annually.

“It is extremely important to suppress the pool of people who may be susceptible to the virus,” he told CNBC’s Bertha Coombs during an event with CVS Health. He added that the vaccines will be an important tool in the fight against highly contagious variants.

Pfizer said earlier this month that updated data from its clinical trial showed that its vaccine is highly effective six months after the second dose.

In February, Pfizer and BioNTech announced that they were testing a third dose of their Covid-19 vaccine to better understand the immune response against new variants of the virus.
