Five states have fewer than 10% of their intensive care unit beds available, according to federal data.

Alabama has reached 100% ICU capacity, while Georgia is at 94% capacity, Florida at 93.18%, Mississippi at 93.01% and Texas at 92.72%, according to the latest data from the U.S. Department of Health and Human Services.

Nationwide, nearly 78% of staffed adult ICU beds are occupied, according to HHS, as the U.S. continues to experience its steepest increase in COVID-19-related hospitalizations since the winter of 2020. There are nearly 93,000 patients now hospitalized across the country with COVID-19, according to federal data.

Overnight, the U.S. recorded its fourth day with more than 140,000 new COVID-19 cases in the last seven days. The country's new case average has now surged to 130,000, up 13.2% in the last week, an ABC News analysis found.

More than 1 million COVID-19 vaccine doses were administered in the past 24 hours, including 562,000 first doses, a White House official confirmed to ABC News Thursday.

It's the first time 1 million doses in a single day have been logged in close to seven weeks, the official added, "a 31% week-over-week increase in the daily average of people completing their vaccine series."

The United States' early vaccine program likely helped prevent nearly 140,000 deaths during the first five months that shots were available, according to research published in the journal Health Affairs Wednesday.

Death reduction differed by state. New York saw the greatest reduction in COVID-19 deaths, while Hawaii saw the smallest benefit. "Overall, our analysis suggests that the early COVID-19 vaccination campaign was associated with reductions in COVID-19 deaths," the researchers wrote.

Top scientists at the World Health Organization pushed back against the Biden administration's intention to supply booster shots to Americans beginning next month.

"We’re planning to hand out extra life jackets to people who already have life jackets, while we’re leaving other people to drown without a single life jacket," Dr. Mike Ryan, executive director of the WHO’s health emergencies program, told reporters Wednesday. "That’s the reality."

As of Wednesday, 60% of Americans had received at least one dose and 51% were fully vaccinated, compared with 32% of people worldwide who've gotten at least one shot and 24% who are fully vaccinated, according to data from the CDC and Our World in Data.

The University of Virginia has cut 238 students from its rolls after they failed to comply with the university's vaccination policy, school officials confirmed to ABC news.

"We first announced this vaccination requirement on May 20 and the deadline for compliance was July 1," Brian Coy, a spokesman for the university, told ABC News in an email.

"Since then, students received multiple reminders about this policy and the need to either be vaccinated or request a medical or religious exemption. Students who remained out of compliance after the deadline received multiple communications in the form of emails, texts, phone calls, and in some cases phone calls to their parents. The University’s vaccination policy was also covered extensively on our digital platforms, our daily news product, the student newspaper, and local media all over Virginia."

The university has given the students until Aug. 25 to comply or they won't be allowed to come back school in the fall.
