Michigan has the highest infection rate, followed by Minnesota and New Mexico.
As the COVID-19 pandemic has swept the globe, more than 5.1 million people have died from the disease worldwide, including over 771,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.
Just 69% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the U.S. Centers for Disease Control and Prevention.
The CDC's independent advisory committee on Fridayvoted unanimously to recommend that everyone 18 and older who was vaccinated with Pfizer or Moderna at least six months ago can get a booster.
The FDA authorized Pfizer and Moderna boosters for all adults earlier on Friday.
The last step in the regulatory process will be CDC director Rochelle Walensky issuing her recommendation.

Dr. Anthony Fauci says he's hopeful a COVID-19 vaccine could be available for children under 5 next year, but studies can't be rushed, making an exact timeline uncertain.
"Hopefully within a reasonably short period of time, likely the beginning of next year in 2022, in the first quarter of 2022, it will be available to them," Fauci told Insider, adding, "Can't guarantee it, you've got to do the clinical trial."
Pfizer's pediatric vaccine trials are already underway. The company estimates it could have early results for young children ages 2-4 by the end of the year, meaning authorization is possible sometime next year. Moderna is further behind, but also has ongoing trials in children as young as six months.
Clinical trials don't always unfold on a predictable timeline, and experts emphasize studies in young children won't be rushed.

The FDA on Friday said it has authorized Pfizer and Moderna boosters for all adults, six months after the second shot.
“With boosters, more adults will now have the opportunity to help preserve a high-level of protection against this disease," Pfizer CEO Albert Bourla said in a statement.
“This emergency use authorization comes at a critical time as we enter the winter months and face increasing COVID-19 case counts and hospitalizations across the country,” Moderna CEO Stéphane Bancel said in a statement.
As for next steps, the CDC's independent advisory committee is meeting Friday afternoon to discuss boosters for all.
