This Twitter Doctor, Dr.Krutika Kuppalli made a great point that these Monoclonal Antibodies were used as a treatment for EBOLA and said these antibodies are used for EMERGING INFECTIONS (Including Covid, not just HIV and EBOLA and FUTURE infections we have not encountered yet.) :
Trump received #Regeneron which is an antibody cocktail and is now receiving #remdesivir a nucleotide analogue.
Ironically both remdesivir and monoclonal antibody cocktails have been studied in other emerging infections such as #Ebola.
