An independent FDA advisory panel on Thursday and Friday is set to discuss and vote on whether to authorize Moderna and Johnson & Johnson Covid-19 vaccine boosters for those 18 and older.

On Thursday, the panel will discuss and vote on a potential Moderna booster, and hear presentations from both the company and FDA representatives; Israel's director of public health health will give a presentation about the results of Pfizer booster shots in that country.

The FDA panel will ask questions and debate the benefits versus risks of a Moderna booster and an initial, non-binding vote on the Moderna booster has been scheduled for Thursday afternoon.

On Friday, the panel will discuss and vote on a Johnson & Johnson booster, in addition to hearing NIH's presentation on mix and match booster data.
