I'm referring to my own clinical and scientific perception, which seems to be shared among my peers, but I didn't run a comparative study. Right now, chloroquine is cheap. I suspect that will change. As for plasma yes, every step from collection to administration is expensive if you want to keep with the current safety level. And other people need plasma too... Plasma toxicity worries currently comes more from transfusion-related reactions than from infection. Hospitals have very limited capacity in term of production. Just starting with the fact that you'd have to find enough volunteers in the first place, but even so a hospital is not a factory.
