White House chief medical adviser Anthony Fauci on Sunday warned of a possible spike in coronavirus cases as the U.S. heads into the winter months. 

Fauci told CNN’s Dana Bash on Sunday that people moving indoors, waning vaccine-born immunity and millions of unvaccinated Americans creates a potentially dangerous situation. 

“That results in the dynamic of virus in the community that not only is dangerous and makes people who are unvaccinated vulnerable, but it also spills over into the vaccinated people, because no vaccine is 100 percent effective,” Fauci said.

“And when you have a lot of virus circulating around, we know that there are breakthrough infections, and that's how you get the uptick in cases,” he added. 

Daily COVID-19 cases increased by 29 percent in the past 14 days with the country reporting more than 93,000 cases per day.

But the director of the National Institute of Allergy and Infectious told the outlet Americans can still safely enjoy the upcoming Thanksgiving holiday — especially if they are vaccinated. 

“Obviously, if you're not vaccinated, you're in a situation where you're more vulnerable to getting infected,” Fauci said. “But for the people who are vaccinated, the people who can get boosted, enjoy your holiday season with your family, indoors, grandparents, children. Do it.”

“But be aware that, when you are in a situation where you are traveling, for example, and you are in an indoor, congregate setting, and you don't know the vaccination status of people, you need to wear a mask,” he said.

The Food and Drug Administration on Friday authorized both Pfizer and Moderna’s COVID-19 vaccine boosters for all U.S. adults ages 18 or older. Currently, around 18 percent of the country has received a booster. Meanwhile, slightly more than 59 percent of the total U.S. population is fully vaccinated.
