Hard-hit Louisiana has 2,907 COVID-19 patients in hospitals -- more than any point of the pandemic so far, the state's Department of Health said Friday.

Louisiana's Ochsner Health said they have 1,063 hospitalized COVID-19 patients in their system, exceeding all previous surges. Of those patients, 88.99% are unvaccinated, officials said.

Gov. John Bel Edwards said 399 patients in the state are on ventilators.

Fifty-seven people died of COVID-19 in Louisiana in the last 24 hours, the health department said.

The governor warned Friday that Louisiana isn't near the peak of this surge and hospital leaders are more alarmed now than at any point in the pandemic.

"We are really close to the breaking point," Edwards said.

Federal officials are deploying extra resources to COVID-19 hot spots, including sending five "fatality management trailers" to Texas, according to a federal planning document obtained by ABC News.

Oklahoma was set to receive 100 ventilators on Thursday, according to the planning document, while Mississippi has requested enough medical personnel to staff more than 1,000 beds.

Chicago Public Schools, the nation's third-largest school district, is requiring all employees to be vaccinated.

Seventy-eight percent of district employees were already fully vaccinated, partially vaccinated or had a vaccination scheduled as of June, the district said.

"For the social and emotional well-being of our young people, they need to be in school, and the vaccine adds another layer of protection to our plan to safely re-open schools," the city's department of public health commissioner, Allison Arwady, said in a statement.

Chicago's school year starts on Aug. 30.

Dr. Richard Besser, president and CEO of the Robert Wood Johnson Foundation and former acting director of the CDC, told "Good Morning America" that he expects booster shots will "be available to people with immune disorders very quickly."

The FDA announced late Thursday that immunocompromised Americans – such as cancer patients, transplant recipients, people with HIV and people on immunosuppressant drugs -- will be able to get a third shot of Pfizer or Moderna.

But Besser stressed, "I think about this less as a booster shot" and more of "a recognition that for certain people with immune problems, two doses wasn’t enough" and "the third dose is necessary for them to get the same high level of protection that the rest of people do."

The CDC panel is expected to vote to recommend the third dose when it meets Friday at 11 a.m. and CDC Director Rochelle Walensky will likely sign off after a Friday afternoon vote.
