“It is extremely important to suppress the pool of people that can be susceptible to the virus,” Bourla said.
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 the coronavirus 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.
