COVID-19 vaccine maker Moderna will make a third booster shot for its two-dose vaccine available to Americans by the fall, CEO Stéphane Bancel said this week.


Moderna's vaccine is more than 90% effective against the coronavirus six months after the second shot, studies show. What remains unclear is how long immunity from the virus lasts.

"There will be likely a need for a third dose, somewhere between six and 12 months. And then from there, there will be an annual revaccination. But all of that needs to be confirmed," Pfizer CEO Albert Bourla said Thursday at a virtual event hosted by CVS Health.
