A panel of expert advisors gave the thumbs up to J and J's covid 19 vaccine on Friday.

That recommendation then goes to the U.

S Food and Drug Administration, which is likely to grant authorization for its emergency use within a day or so, setting the stage for a planned rollout of 3 to 4 million doses 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 Moderna.

And it would be the only one that requires just one shot.

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

That makes distribution a lot easier.
