I'm not sure what you're not getting here. There were three scenarios studied:
1) RCTs of the three-drug cocktail in hospitalized patients. Shown to be ineffective.
2) RCTs of hydroxychloroquine only in early-onset patients. Shown to be ineffective.
3) Observational trials of the three-drug cocktail given early well before potential hospitalization was necessary. Shown to be extraordinarily effective.
But because Fauci only considered 1 and 2 and dismissed 3, the mantra became, "It didn't work."
He's been proven wrong. Had Dr. Risch or Dr. Fareed been the head of the NIH instead of the incompetent Fauci, we wouldn't have 300,000 dead.
