(CNN) Federal regulators are considering limiting the authorization of certain monoclonal antibody treatments that have not proved effective against the Omicron variant of the coronavirus , a source familiar with the decision-making told CNN. "And it's something that we actually have seen applied with Omicron patients and we have seen symptoms resolved." Regeneron has publicly stated its monoclonal antibody treatment is not effective against the Omicron variant. Greg Abbott last year opened state-sponsored "infusion centers" where Covid-positive patients could receive monoclonal antibody treatment. The fast-spreading Omicron variant was first detected in the US on December 1, and quickly became the predominant variant.
