How worried should you be about the uptick in Covid-19 cases and the emergence of the Omicron variant of the coronavirus? The answer very much depends on who you're listening to. US authorities want vaccinated Americans to live their lives.
President Joe Biden, even as he acknowledged expectations of a surge in cases of the Omicron variant, sought to assure Americans -- vaccinated and boosted Americans, that is -- to go ahead and celebrate their holidays. "If you are vaccinated and follow the precautions we know, well, you should feel comfortable celebrating the Christmas holiday as you plan to," he said during a speech from the White House on Tuesday. "You know, you've done the right thing. Enjoy the holiday season." World health officials sounded very different.
