CHARLOTTESVILLE, Va. (CBS19 NEWS) -- Intensive care unit beds at the University of Virginia Health Systems are near capacity.

It was announced Friday morning at a UVA COVID-19 Health briefing that a contributing factor is the rise in COVID-19 cases in those who are unvaccinated.

"Our ICU's are near capacity. We are staffed at 86 ICU beds out of 93 total ICU beds today," said Dr. Wendy Horton, UVA Health's chief executive officer.

UVA Health confirmed that of patients hospitalized for COVID-19, 90 percent of them are unvaccinated. And of the 10 percent who are, they are strongly immunocompromised or are of older age.

Currently, UVA Health has 59 COVID-19 hospitalizations and 27 of those hospitalizations are in the ICU.

On Friday, the Centers for Disease Control and Prevention announced that the Pfizer booster shot will be recommended for people who are at high risk.

That means people who have compromised immune systems or who are over the age of 65.
