That a widely-disputed "leader" is "promoting" a treatment in a country as diverse and with as many systemic issues as Brazil, has no necessary bearing nor indication of that treatments actual use or resultant efficacy.

That you have a friend that took it and went to the ICU is similarly meaningless. What dosage did he take? What other predispositions did he have? How badly was he exposed? What other treatments were used? Did he keep taking it throughout, or not? You say he's recovering now, would he have died without it, then?
