The Food and Drug Administration has granted Moderna’s two-shot coronavirus vaccine emergency use authorization, the second vaccine to be approved in one week.

The agency made quick work of authorizing the vaccine just one day after its vaccine advisory panel recommended by a vote of 20-0, with one abstention, that it be approved for limited public use. Similar to last week’s authorization of Pfizer’s vaccine, the first doses of the Moderna vaccine will be shipped out over the weekend to be delivered to U.S. hospital systems Monday through Wednesday.
