That panel of doctors, infectious disease experts and medical researchers is expected to vote in favor of the vaccines use at the end of the meeting.

The Food and Drug Administration is then likely toe authorize it for emergency use within a day or so, with 3 to 4 million doses expected to be rolled out next week.

That would make J and J's vaccine the third one available in the U.

S.

After those made by Pfizer beyond Tech and Madonna.

And it would be the only one that requires just a single injection.

Unlike the other two, J and J's vaccine can be stored in normal refrigerator temperatures instead of ultra cold storage.

That makes distribution ah, lot easier.

A trial found that J and J's vaccine was 66% effective at preventing moderate to severe cases of CO vid 19, and it was 100% effective at preventing hospitalizations 28 days after vaccination.
