High-risk Covid-19 patients can be prevented from getting sick by usingonoclonal antibody treatments. The treatments worked against the previous versions of the virus, but the omicron's mutation in a spikeProtein targeted by the treatments all but eliminated their effectiveness. Hospitals such as NewYork-Presbyterian Hospital stopped offering the treatments a month prior to the FDA announcement. The Centers for Disease Control and Prevention said that Sotrovimab appears to work against omicron. Hospitals in New York, Maine, Texas and other states have had difficulty maintaining supplies of sotrovimab. The White House said in December that they would ship 300,000 sotrovimab doses to state and territorial health departments in January. The federal government agreed to purchase 600,000 more doses of the drug.
