Pfizer CEO Albert Bourla said that those who have received the Pfizer COVID-19 vaccination will likely need a third shot of the Pfizer/BioNTech COVID-19 vaccine within 12 months after being fully vaccinated.
“A likely scenario is that there will likely be a need for a third dose, somewhere between six and 12 months,” Bourla said. “And then from there, there will be annual revaccination, but all of that needs to be confirmed.”
Bourla said that COVID-19 variants would “play a key role” in determining what vaccinations will be needed in the future.
Bourla added that our country’s primary focus currently should be vaccinating the population now to prevent the virus’s spread.
It is still unknown how long exactly the vaccines protects someone once they’ve been fully vaccinated.
Earlier this month, after a study was conducted on more than 46,000 trial participants, Pfizer said its vaccine was more than 91% effective.
Pfizer said that after people received their second dose, the vaccine was 95% effective.
