To use convalescent serum in a single patient you need to get FDA approval ... convalescent serum has been used since before 1900... WTF!!!https://www.fda.gov/vaccines-blood-biologics/investigational-new-drug-ind-or-device-exemption-ide-process-cber/investigational-covid-19-convalescent-plasma-emergency-inds …
Do you know if the blood types need to match in order for the convalescent serum to work?
