so the problem now there are very few mab vials in circulation of fda approved cos to help the very sick.remdesivir will not do for the severe/critical what leronlimab will do.

"Martin Landray of the University of Oxford, who is co-leading the world's largest study of various COVID-19 treatments, says remdesivir "definitely doesn't work in the sickest patients where the biggest gains would be" but might help people at earlier stages of disease. Further complicating the matter, most people infected with SARS-CoV-2 recover without any intervention. "The argument that the earlier you use it the better is great until you realize what the implications of that are: You won't save many lives, and you'll have to treat a lot of patients," Landray says. "It's very inconvenient, and it'll cost you a fortune."
