NIAID director Anthony Fauci warned Wednesday that large gatherings this holiday season are unsafe even for fully vaccinated people who've had a COVID-19 booster shot, as the Omicron variant surges across the U.S.
What he's saying: "There are many of these parties that have 30, 40, 50 people in which you do not know the vaccination status of individuals," Fauci said at a briefing. "Those are the kind of functions in the context of Omicron that you do not want to go to."
- Fully vaccinated families should be safe to attend smaller gatherings, Fauci said.
What to watch: Fauci noted that early research from the U.K. and South Africa indicates that Omicron may be less severe than other variants.
- But he added: "We must wait to see what happens in our own population, which has its own demographic considerations."
