The emergence of an Omicron sub-variant, BA.2, has made it even harder to get the right monoclonal antibodies to the right patients. Vaccines still prevent severe disease from the Omicron variant because they prompt the body to develop antibodiesand more complicated systems, like white blood cellsfor a whole range of bricks. Hospitals, drug companies and Biden administration officials are racing to address one of the Omicron variants biggest threats: Two of the three monoclonal antibody treatments that doctors have depended on to keep Covid-19 patients from becoming seriously ill do not appear to thwart the latest version of the coronavirus.

FDA authorizes new monoclonal antibody treatment to fight More recent antivirals, particularly the pills molnupiravir and Paxlovid, could, in the end, provide better options for patients. Despite the inconvenience, monoclonal antibodies went into widespread use for treating Covid. We did that because we felt there was utility early on in being able to say on the same day, this person likely has Delta, and so they can have Regeneron, and this person likely has Omicron, and they could get sotrovimab, says S. Wesley Long, the clinical director of diagnostic microbiology at Houston Methodist Hospital. Ensuring that healthcare providers on the frontlines have the best tools available to treat patients is a top priority for the agency. Early data suggests that this new product by Lilly has activity against both Omicron and the BA.2 Omicron subvariant, HHS said.
