I guess except for these 700 studies, 20 of which involve vitamin D.

Seems like a ridiculous claim when I'm sure almost absolutely everyone would like to get out of this mess.

It shouldn't be hard to sit for a moment and think of some people who would certainly like for there not to be a treatment consisting of ~$3-5 worth of off-the-shelf, completely unpatentable medicines and vitamins.

There are absolutely some powerful vested interests in not seeing an easy treatment for this disease, or, by the same logic, pretty much any other disease either since there's nothing special about this one. (A not infrequent complaint on Hacker News.) I can't prove they're driving the discourse on treatment for COVID-19, but it sure isn't disproved by what I see happening out there.

The original claim said "invested in the belief that there is no treatment for it", not "no inexpensive treatments".

What you are rebutting is not against what OP is claiming.

You cannot fast-track a vaccine if there are other treatments available. Letting the word out that you can be cured from COVID-19 could make a lot of people lose much money. Both Vitamin D and the other one (it rhymes with byfroxymorophin) are cheap and out of patent.

There are seven results for American trials found on clinicaltrials.gov for Condition= "COIVD19" and Drug = "VitaminD" run by institutions like Harvard/MGH, Brigham, UNC, Arizona State University, etc.

Thank you. Perhaps my stance is too cynical.

Huge numbers of trials have been done in the US, including some showing promising results (for steroids at least).
