What Other Medicine Have Been Trialled?

Of these sufferers, 266 received a single intravenous infusion of two,four hundred milligrams casirivimab and imdevimab , 267 obtained 8,000 mg casirivimab and imdevimab , and 266 acquired a placebo, inside three days of acquiring a positive SARS-CoV-2 viral check.
