About 62% of the population in the United States is fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
The United States has recorded 2.2 million confirmed COVID-19 cases over the last week, setting a grim record as the highest number of cases confirmed in one week.
The previous record was set just a few days earlier from Dec. 22 to Dec. 29, when the U.S. confirmed 1.9 million COVID-19 cases. Before that, the previous record totaled 1.75 million cases from Jan. 5 to Jan. 11 at the start of 2021.

More COVID-19-positive children in the United States are being hospitalized each day than at any other point in the pandemic, according to newly updated federal data.
On average, just under 380 children with COVID-19 were admitted into the hospital daily between Dec. 22 and Dec. 28, according to data from the Centers for Disease Control and Prevention.
The country's pediatric COVID-19 hospital admission rate has nearly tripled in the past month, CDC data shows.
Nationwide, nearly 2,900 children are currently hospitalized with confirmed or suspected cases of COVID-19 -- approximately 1,300 more patients than a month ago -- according to data from the Department of Health and Human Services.
Less than a third of eligible children -- ages 5 to 17 -- in the U.S. are currently fully vaccinated against COVID-19.
Three new studies released Thursday by the CDC found COVID-19 vaccines to be safe and effective for children.
