Lemme try again 😆 the blurb says that it is issued before folks bet to hospital to keep them out, used in mild to moderate cases. I think the ones you mentioned are more for cases that are moderate to severe after they have been admitted
No, the monoclonal infusions like Regeneron have always been for early in the infection and weren’t given after admission to the hospital. Covid is two stages - the infection stage when antibodies are helpful, and the inflammation stage when antibodies are useless (because you don’t really have the active infection anymore) when the cytokine and other inflammatory causes are damaging organs.
The infection stage, up to seven days after symptoms develop, iirc, is when monoclonal treatments are given.
The inflammation stage is when steroids, etc, are given to tamp down the inflammatory response.
