Pfizer CEO Albert Bourla says people are likely to need a booster dose of the vaccine six to 12 months after their first round.
From there, it will be an annual re-vaccination.
Bourla shared the news during a CVS Health live event posted to Facebook Thursday.
He also added that real-world data shows the Pfizer vaccine is effective against a worrying variant of coronavirus first seen in South Africa.
