Pfizer CEO Albert Bourla said people will “likely” need a third dose of a Covid-19 vaccine within 12 months of getting fully vaccinated. His comments were made public Thursday but were taped April 1.
He also said it’s possible people will need to get vaccinated against the coronavirus annually.
“It is extremely important to suppress the pool of people that can be susceptible to the virus,” he told CNBC’s Bertha Coombs during an event with CVS Health. He added the vaccines will be an important tool in the fight against highly contagious variants.
The comment comes after Johnson & Johnson CEO Alex Gorsky told CNBC in February that people may need to get vaccinated against Covid-19 annually, just like seasonal flu shots.
Researchers still don’t know how long protection against the virus lasts once someone has been fully vaccinated.
Pfizer said earlier this month that its Covid-19 vaccine was more than 91% effective at protecting against Covid and more than 95% effective against severe disease up to six months after the second dose. Moderna’s vaccine, which uses technology similar to Pfizer’s, was also shown to be highly effective at six months.
Pfizer’s data was based on more than 12,000 vaccinated participants. However, researchers say more data is still needed to determine whether protection lasts after six months.
