U.S. health officials say COVID-19 antibody drugs from Regeneron and Eli Lilly should no longer be used because they don't work against the omicron variant.

The infusions are more available and accessible to Texans than ever before, and new criteria for who can receive antibody treatment have led more doctors to prescribe it.

After Governor Greg Abbott’s announcement Tuesday that he tested positive for Covid 19, his communications director says he is receiving the Regeneron antibody infusion therapy.Governor Abbott said he was not feeling any symptoms which has sparked some questions as to who is able to get the monoclonal antibody treatment.

Florida Gov. Ron DeSantis has been criticized for efforts to ban mask mandates and vaccine passports.

Paycom Software’s Chad Richison and Advanced Micro Devices’ Lisa Su are among the top paid CEOs in the S&P 500 index.

In a new White House video posted Wednesday evening, Trump said his illness had shed light on an experimental antibody cocktail that he tied to his improved condition. The White House has released only limited details about his condition and treatment, leading to questions about what lies ahead for Trump. Access to Trump for White House aides has been extremely limited since his discharge. All told, more than a dozen White House staffers have tested positive. He also thanked a supporter who tweeted she “would wade though a sea of COVID infested water to vote for President Trump on November 3rd."

“He’s getting the Cadillac of treatment at this point, very early and very aggressive,” said Dr. Luis Ostrosky, an infectious disease specialist at UTHealth. Ostrosky said the president is being treated with Remdesivir and an antibody cocktail made by Regeneron. He’s also getting Remdesivir, which is the antiviral that we know has some effect against the virus at this point," he said. Trump posted a video on Twitter Saturday from Walter Reed Medical Center addressing his health and the treatments he’s received. According to experts and doctors, the next 48 to 72 hours are crucial to the president’s recovery.

Regeneron’s antibody treatment, referred to as a “COVID cocktail,” is showing promise in reducing the length and severity of the virus in people who have been exposed. It’s an injection of antibodies that could be used to protect caregivers or those who have been exposed to the virus. They’re researching whether injections of REGN-COV2, a combination of antibodies originally isolated from patients who have recovered from COVID-19, could help stop the spread. “Those antibodies...are a rapid response to the people who get COVID and that may help them reduce their symptoms or prevent hospitalizations. Or in this case, rapidly prevent COVID in people who live with people who have been diagnosed with COVID,” Dr. Gioia said.

A vaccine to protect us against coronavirus may be a year or more away but there are other technologies on the horizon that could help protect people from getting the virus. You've heard a lot about antibody treatments when we talk about convalescent plasma. Some of our local hospitals are using blood plasma from survivors to help sick patients make a recovery. Regeneron and Eli Lilly are among American favorites to develop antibody treatments. Those antibody treatments, they say, could be ready by the end of this year.
