FDA analysis finds Johnson & Johnson COVID vaccine is safe and effective

The Food and Drug Administration's staff released a briefing document on Wednesday endorsing Johnson & Johnson's one-shot coronavirus vaccine as safe and effective.

The latest: Assuming the FDA issues an emergency use authorization "without delay," meaning as soon as this weekend, White House coronavirus coordinator Jeff Zients said J&J will have 3 million to 4 million ready for distribution next week.

What's next: An FDA advisory panel will meet Friday to review the briefing document and vote on whether to recommend an emergency use authorization (EUA). The FDA will then decide on whether to accept the recommendation and issue the EUA, clearing the way for distribution in the U.S. to begin.
