There were over 7 million shots in the past week, an official said Saturday.
The United States has been facing a COVID-19 surge as the more contagious delta variant continues to spread.
More than 712,000 Americans have died from COVID-19 while over 4.8 million people have died from the disease worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 66% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the CDC.
New York nurse Sandra Lindsay, the first person in the U.S. to get a COVID-19 vaccine outside a clinical trial, plans to get her Pfizer booster dose Wednesday at Long Island Jewish Medical Center in New York.
Other health care workers who also got their first shots in December are planning to join her in getting boosters on Wednesday.
The Department of Homeland Security this week issued an intel notice warning that extremists, including white supremacists and other would-be domestic terrorists, are likely to “threaten violence or plot against healthcare personnel, facilities, and public officials in response to renewed and expanding COVID-19 mitigation measures.”
The document, distributed Monday to U.S. law enforcement and government agencies and obtained by ABC News, noted that anti-vaccine messaging will likely increase as vaccine mandates spread.
The notice warns that some of the misinformation and disinformation now circulating is being pushed and promoted by Russia, China and Iran as a means of sowing anger and discord in the U.S.

Seventy-six percent of Americans ages 12 and above have had at least one vaccine dose, White House COVID-19 data director Cyrus Shahpar said Tuesday.
Now 65% of the total U.S. population has had at least one dose, he said.
A federal judge has declined to impose a temporary restraining order on New York City’s public school vaccine mandate, rejecting a request from special education teachers who were denied a religious exemption.
Michael Kane and nine other educators -- who all said they possess sincerely held religious beliefs that compel them to eschew any vaccine -- sought the temporary restraining order, claiming the mandate violates the free exercise and equal protection clauses of the Constitution.
The educators can try again during a hearing next week at which they’ll seek a preliminary injunction, accusing the state of “hostility” toward religious beliefs that may be outside the mainstream.
New York City, the nation’s largest school district, is one of the first in the country to require school staffers to be vaccinated.
About 95% of the city’s 150,000 Department of Education employees have been vaccinated, including 96% of teachers and 99% of principals, Mayor Bill de Blasio said Monday.
About 8,000 replacement DOE staff members, including 7,000 substitute teachers, were used on Monday, which was the first day of the vaccination mandate.
