White House officials Monday said Congress must allocate another $22.5 billion in COVID pandemic relief to avoid imminent cuts to treatment and vaccine availability, but some key Republicans said they want a fuller accounting of the trillions of dollars the administration has already spent on the coronavirus response.

White House officials said Monday Congress must allocate another $22.5 billion in COVID-19 pandemic relief to avoid imminent cuts to treatment and vaccine availability.

The request came despite pandemic relief payments of almost $178 billion made directly to healthcare providers since March 2020.

"Right now, we don't have enough money for fourth [COVID vaccine] doses, if they're called for," said Jeff Zients, White House coronavirus coordinator during an episode of "In The Bubble With Andy Slavitt," recorded Monday and shared with The Washington Post.

"We don't have the funding," said Zients, "if we were to need a variant-specific vaccine in the future."

The White House last week released a statement detailing the consequences if Congress doesn't provide additional COVID relief funding.

According to the statement:

The administration on Tuesday stopped accepting new claims to reimburse providers for COVID testing and treatment.

On April 5 it will stop accepting vaccination claims for uninsured patients for reimbursement, leaving the uninsured to pay for their own shots.

The administration will not have funds to cover a fourth booster for "every American."

The administration also plans to stop purchasing monoclonal antibody treatments and will run out of supplies to send to states by late May.

The administration will run out of funds to purchase oral antiviral treatments, such as Paxlovid and molnupiravir.
