If you are waiting on "hard data" then you are missing the point.

It doesn't have to actually be a cure-all, it just has to sound like one to the pleb masses.

Watch as the Covid numbers magically dwindle early next year, news of the "cure" working miracles in the hospitals, the MSM fear mongering subsides, and the masses emerge and begin freely to go about doing their normal routine, and spending money again.

All by design. Biden of course will claim all of the credit.
