Gabe Ivermectin to treat covid is nonsense and it hasn't been 'vindicated'. (edit after posting)Upon re-reading, I guess you mean by 'vindicated' that Joe wasn't actually buying it from the local feed and seed but instead obtained a prescription. True. Still useless, but OK.
That is what I meant.
However it is not at all clear ivermectin is "useless". One of the biggest meta analysis of the data has shown that is likely to reduce serious illness and death by 62%. Remember, worldwide it's one of the safest and most widely used medications (for parasites) so side effects are negligible. Remember those most interested in these alternatives are the very poor - who can't afford the latest treatments. In fact the most recent study that purported to show ivermectin ineffective has been withdrawn amid some scandal (and frankly incredible levels of bad practice).
There have been some major studies that were inconclusive as to its effectiveness, also, and I'm certainly no particular advocate. But I do think you need to look harder into the levels of vested interests and dishonesty when it comes to pharmaceuticals. Certainly vitamin D and other essential fatty acids you can get from spouted seeds etc mentioned by Vintage are super good for you.
I'm very science orientated and an advocate of modern medicine being a nurse, but never throw the baby out with the bath water!!
I'm big into gut health and fermented foods (which humans have ingested for millennia - always a good sign something is healthy for your immune system). I think foraging and eating as wide a range of foods as possible is another modern "fad" that I happen to think is really beneficial.
