(KTEN) -- Texas Rep. Pat Fallon (R-District 4) wrote a letter asking President Biden to do his part in distributing more COVID-19 monoclonal antibody treatments.

Fallon claims changes at the federal level has made the purchasing process more difficult for states.

One of the problems: The two monoclonal antibody treatments that were effective against earlier variants of COVID are less useful for patients with the omicron variant. 

"We are supposed to get six this week and we have not received them yet. That's the scary part," said pharmacy manager Reba Jones at Mercy Ardmore hospital.

"President Trump said anyone who needed a ventilator would get one, and that's exactly what happened," Fallon said.

On Monday, the congressman asked for the same commitment from President Biden regarding monoclonal antibody treatment.

Fallon asked Biden to let states purchase the treatment directly from manufacturers, an option that had previously been available.

"And then the Biden administration said they would purchase and allocate an equitable supply to the states," Fallon said.

So, he expects the president to be true to his word.

"We had to fight a few months back to ensure that one of our counties got the 50 doses they were promised, because people were coming in that Saturday to get the treatment," Fallon said. "I knew statistics would show one of those folks would probably lose their life if we didn't get that treatment to them."

The Texas lawmaker credits monoclonal antibody treatment with saving his life in February 2021 when he was hospitalized with COVID and pneumonia.

Texas Republican Gov. Greg Abbott — who also received monoclonal treatment after testing COVID-positive last August — made a plea for antibodies after five state treatment facilities had to shut down due to lack of supplies. The governor also asked for resources to open additional treatment sites.

"It's rough right now," Reba Jones said. "As many as we get in, we are going to use in on the patients until we don't have it anymore."

Abbott and Oklahoma Republican Gov. Kevin Stitt (who was also diagnosed with COVID-19 last July) have both rejected federal, county, city and school vaccine and mask mandates for their citizens.
