A Food and Drug Administration advisory panel on Friday recommended the authorization of Johnson & Johnson’s one-shot coronavirus vaccine for emergency use.

Why it matters: The FDA is expected to make a final decision within days on the J&J vaccine, which was found to be 66% effective against moderate to severe COVID. An emergency use authorization would allow distribution to immediately begin, helping streamline and speed up the vaccine rollout across the U.S.

• White House coronavirus coordinator Jeff Zients said on Wednesday that J&J will have 3 million to 4 million ready for distribution next week.
• The Moderna and Pfizer-BioNtech shots are the only other vaccines that have received FDA authorization. Unlike Moderna's shot, J&J's vaccine does not require ultra-cold storage, simplifying the logistics of distribution.
