It was interesting to see Facui so quickly endorse remdesivir but perhaps he did so because it's safer than choloroquine. It is convienent that remdesivir costs $1000 to 4000 per patient, whereas choloroquine is basically free compared to that.

And this: "Before the Covid outbreak, remdesivir was a drug for which Gilead had failed to find a use." (Barrons 6/2/2020)
