Those treatments had been successful at keeping symptomatic patients out of the hospital in earlier waves,. A third, less common monoclonal treatment, called sotrovimab, can still be used.
For much of early 2021, supplies of the drug were limited, and they were given only to people at high risk of severe COVID. But by this fall, the federal governmenttens to hundred of thousands of doses per week. Some states, including Louisiana and Florida, opened state-run infusion centers where anyone could come in to receive treatment.
, takes at least a few days, but often stretches into a week—by which time, the window for antibody treatment has passed. And most of the sequencing is currently done at a lower standard than the FDA requires for clinical decision-making. PCR tests used by some healthcare institutions could detect one telltale mutation on Omicron, while others, like Houston Methodist Hospital in Texas, rolled out a test that could distinguish between strains as Omicron spread.
