Do NOT underestimate the stupid throughout this world. You may be proven incredibly incorrect.
On a more serious side, I am most completely NOT a virologist, scientist, etc. I like to think like one as best I can, but will admit my level of Google stupidity overall. I can accept any number of reasons why not to test all drugs, and it makes complete sense. But, just as often, happenstance leads one drug to another cure. Looking for solution A, but finding solution-B. I accept that as reality as well. The ability for our bodies to do weird things at unexpected times is nerve-wracking. I simply admit I don't understand it. I trust that scientists, for the most part, are looking out for the well being of as many people as possible, and that money still drives so many things as to make some solutions a bad profit making decision. It doesn't mean I believe that anyone should follow bad science. That's pretty stupid in my view. But, I do believe that an expired patent means it's not as likely to be studied. Fortunately, there are some who will try all sorts of solutions. I'm grateful for that, and will still be get my booster shot shortly.
