As the COVID-19 pandemic has swept the globe, more than 5.4 million people have died from the disease worldwide, including over 825,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.

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.

US daily case average nearly triples in 1 month

More than 84,000 Americans are currently hospitalized with COVID-19 -- a 40,000 jump over the last seven weeks, according to federal data.

In the last month, federal data shows the nation's daily case average has nearly tripled.

A soaring demand for tests and a backlog of holiday reporting drove Monday's case total to 440,000 -- the nation's highest one-day total ever, according to federal data.

While this high reflects the latest omicron surge, it's also very likely skewed due to a backlog in reporting over the Christmas weekend and an increase in demand for tests.

Decision on boosters for kids 12-15 could be made in 'days to weeks ahead'

The FDA and CDC could decide on boosters for children ages 12 to 15 in "the days to weeks ahead," CDC Director Rochelle Walensky told CNN's "New Day" Wednesday.

The CDC authorized the Pfizer vaccine for 12- to 15-year-olds on May 12, meaning some of those kids are now over six months past their second dose, which was when boosters were recommended for adults.

Walensky also noted that vaccine manufacturers are working to acquire data for children under the age of five, but an authorization "will not be in the month ahead."

"Domestic flights has been a topic of conversation, but that is not something we're revisiting right now," Walensky said Tuesday.

This comes after Dr. Anthony Fauci told MSNBC's "Morning Joe" on Monday that a vaccine requirement for domestic air travel should be "seriously" considered.
