OHM20...To your point efficacy...clearly, after more than a decade of trials...and more than 1500 patients...the three that died in Brazil...two were on placebo...and the third suffered co-morbidities and illicit drugs in their system...
THIS should have been defined and cleared some time back by a post mortem and the attending officials.
I am tired of seeing commercials that have death as an SAE...and time marches on.
