Florida Gov. Ron DeSantis has vowed to fight a decision from federal health regulators to block two coronavirus antibody treatments after the drugs were found to be ineffective against treating the widespread omicron variant.

The FDA's move to revoke authorization was not unexpected because the drugmakers said the infusion drugs are less able to target omicron because of its mutations. Omicron now accounts for nearly all U.S. infections.

The Florida Department of Health is shutting down all state-run monoclonal antibody treatment sites until further notice after the Food and Drug Administration revoked its emergency use authorization for Regeneron.

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.

Patients interested in receiving monoclonal antibodies were ready and waiting Tuesday morning outside a new treatment center on Jacksonville’s Southside before the doors even opened at 9 a.m.

The state of Florida will open five additional monoclonal antibody treatment sites — including one in Jacksonville — starting Tuesday.

Florida is ready to open additional monoclonal antibody treatment sites, including another site in Jacksonville, if the state gets more supply from the federal government, Gov. Ron DeSantis said Tuesday.

When it comes to treatment of COVID-19, options are limited, and the omicron variant has proved to be an even bigger challenge for providers.

Gov. Ron DeSantis on Thursday announced the state is purchasing 3,000 doses of a new monoclonal antibody treatment after the Biden administration made the decision last week to limit the number of Regeneron doses received by Florida and other states.

While Florida looks to round the corner on administering 100,000 monoclonal antibody treatments to people with COVID-19, Gov. Ron DeSantis pledged Thursday to “fight like hell” to continue receiving the treatments as the federal government this week took control over distribution of the drugs.

New signs are posted at the makeshift antibody clinic at Jacksonville’s downtown library, days after a photo showing sick people lying on the floor there went viral.

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

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."
