Exactly. There is too much clinical evidence that it does work. Like all medications it will not work for everyone. It is also part of a treatment/preventative regimen. When used in protocols developed by doctors such as Paul Marik, MD. it does reduce severity of Covid. Best of all it has a low risk to high benefit.
Just because some meds don’t work for everyone, doesn’t mean they don’t work for no one and therefore they need to be banned from any use at all.
I think you are closest to the truth on this issue.
There was never a clinical trial for the use of Viagra, but men in the trials of Viagra as a heart medication reported much stronger erections. Since it was proven to be safe, there was no real need for an official clinical trial. It was initially approved for an off-label use.
