President Biden said Americans who are fully vaccinated and boosted against COVID-19 can safely celebrate the holidays with loved ones despite concerns about the Omicron variant. On Tuesday (12/21), the president said: "If you are not fully vaccinated, you have good reason to be concerned ... If you are vaccinated and follow the precautions that we all know well, you should feel comfortable celebrating Christmas and the holidays as you planned it. You know you've done the right thing, you can enjoy the holiday season."
