Moderna moves forward on plan to increase Covid vaccine supply in each vial after latest FDA feedback - CNBC

Moderna said Monday it received "positive feedback" from the Food and Drug Administration on its proposal to increase the number of Covid-19 vaccine doses in each of its vials.

One vial of Moderna's two-shot vaccine contains ten doses, enough to inoculate five people, according to the Centers for Disease Control and Prevention.

It's unclear if the increase of doses per vial is why Moderna now expects it can deliver 300 million doses by the end of July.

In December, the FDA said health-care providers could use extra doses from vials of Pfizer's Covid-19 vaccine.
