I don't have any data to support that hypothesis BUT...

If true, that would explain the HUE AND CRY to discredit it to be widely prescribed for CV19.

Just imagine giving it to a lot of old people to prevent them catching it, many of whom, are cancer patients... and have their tumors unaccountably go into remission.

That would certainly be worth kicking a fuss about, losing all that potential money of chemo, and radiation, and hopitialization and surgery in the medical system to a cheap prescription drug.

Like I say... I don't have any evidence to support... BUT! It certainly makes you think.

Because the current amount of resistance doesn't make any sense even if you factor in the Trump Derangement Syndrome.
