Fauci says if we didn't have the tools, he'd be way more worried about omicron
Asked how worried Americans should be about omicron and a post-holiday surge, Dr. Anthony Fauci said that if we didn't have vaccines, boosters and masks he'd "really be worried."
"But we have tools. So get vaccinated, get boosted," Fauci said at Wednesday's White House COVID-19 briefing.
CDC Director Rochelle Walensky said the agency expects to see omicron continue to grow.
"What does this mean for individuals and families as we head into the winter months? A time when families may be gathering with one another over the holidays? It means that it is vital for everyone to get vaccinated and boosted if they are eligible," Walensky said.
White House COVID-19 response coordinator Jeff Zients added, "We're not going to shut down our economy in any way. We're going to keep our schools and our businesses open."

France to ban non-essential travel with UK over omicron surge
France announced Thursday that it will ban non-essential travel to and from the United Kingdom due to the country's surge in cases of the omicron variant.
Starting Saturday, France will require people to have "a compelling reason" to travel between the two countries. Travel for tourism or work will not be allowed. French citizens, however, can return to France, according to a statement from the French prime minister's office.
All travelers from the U.K. will be required to show proof of a negative COVID-19 test taken less than 24 hours before departure. Upon arrival in France, they must self-isolate for a week, but that period can be ended after 48 hours if they test negative for COVID-19 again.
The new rules apply to people regardless of their vaccination status.
"Faced with the extremely rapid spread of the Omicron variant in the United Kingdom, the Government has chosen to reinstate the need for an essential reason for travel from and to the United Kingdom, and to strengthen the requirement for tests on departure and arrival," the French prime minister's office said in the statement Thursday. "The Government is also calling on travelers who had planned to visit the United Kingdom to postpone their trip."
