According to Johns Hopkins University's tally of cases in the United States, there have been at least 23,754,315 cases of coronavirus in the US, and at least 395,785 deaths.
On Saturday, Johns Hopkins reported 198,218 new cases and 3,286 new deaths.
At least 31,161,075 vaccine doses have been distributed and at least 12,279,180 doses of the vaccine have been administered, according to the US Centers for Disease Control and Prevention.
On Friday, the CDC said new more contagious variants of the coronavirus will likely accelerate the spread of the virus and that means the US must double down on efforts to protect people.
A variant first identified in Britain known as B.1.1.7 is now being found in the US too, and modeling indicates it could worsen the already terrible spread of the virus across the country, the CDC researchers said.
That means people need to try harder to wear masks, avoid gatherings and stay socially distant from one another.
"It means that it is going to be harder and harder to control it. Any of those measures we are going to have to do to a higher degree, including vaccination," said Dr. Gregory Armstrong, who directs the Office of Advanced Molecular Detection at CDC's respiratory diseases division.
