Common knowledge, however what they come up with especially in terms of the "risks of using that therapy" is in some degree conjecture. They don't know the whole picture, they don't (can't) know the cumulative detriment of a lab concocted substance in conjunction with myriad other factors. The don't (really can't) test for the full spectrum of possibilities. They talk a better game than they play. Then they sell it to you as safe, but they are lying through their teeth much of the time. Think of the many substances they've discovered many years later were not good for you in the way they previously purported. Aspirin for one... there are many others. I could dredge up a list simply enough, but won't bother ATM. I prefer to stay away from pharma. I'm not religious about it, I'm not superstitious. I'm fortunate I'm healthy enough physically and mentally to be fine with my attitude.
Edit: Here you go:
And here's an eye-opener:
Now, I have gotten every covid-19 vaccination I could as fast as I could because the scale was very likely tipped in favor of it being beneficial. That had my full attention (from my perspective) all along. I have always gotten my flu vaccinations, never refused a vaccination, never regretted getting one. But pills? I take supplements, likely more than I need, but those are in the nature of things you get from good nutrition but maybe don't get enough of without supplementation. That's way different from pharma, in particular Rx pharma.
