I’m curious if GNBT vaccine is being held back because the perception of peptide vaccines is that the efficacy wears off over time? I know they haven’t done any II/III trials but has Generex shown that previous vaccines they produced provide long term efficacy? ... Or is it that GNBT isn’t a brand name with a lot of Congress holding shares? ... not to be cynical but can that influence FDA/BARDA decisions ... or are decisions on funding made solely by scientists?
