(Speaking of vitamin D, I personally did exactly that with vitamin D + vaccine. My doctor told me a few years back I was low on vitamin D and should supplement anyway, and the vague evidence that it maybe helps against covid was enough for me to decide to take it regularly at a high dose, because there aren't really any downsides besides getting through my bottle faster. But I also got the vaccine!)
If ivermectin was found to be safe and effective and got FDA approval itself, the vaccines of Pfizer, Moderna and J&J would need to get full approval - meaning longer and more rigorous clinical trial and safety testing. (not that they haven't gone through a certain level of those things, just the bar is set lower with EUAs)
p.s. Sounds like you talked to your doctor about supplementing VitD - but you're mistaken to say there aren't any downsides (especially for regular high doses of D) --- It can cause hypervitaminosis D which in turn causes hypercalcemia (a buildup of calcium in your blood). Just saying as it may be worth double checking :)
We do have an alternative that works in theory - if everyone wore an N95 (or knockoff, even!) mask at all times in public, indoors and outdoors, and if all restaurants did takeout only, the risk of transmission would be extraordinarily low. And it's not zero even with the vaccine. The vaccine does different things from masks, though.
I think money-grubbing Big Pharma execs who were recently regulators on the other side of the revolving door would easily be able to argue that ivermectin (or vitamin D, or whatever), useful as it may be, is not an adequate alternative to the vaccine, just (as you put it) another facet in a multifaceted approach, and the vaccine still needs an EUA.
It's not really that surprising. Prescribing Opioids like candy, outlandish prices for things like Insulin, bankrupting poor and uninsured for end of life treatments, covering up the gain of function research funded by the NIH, censoring all kinds of stuff, beginning with their President and probably a few of their friends. I'm sure some of those anti-vaxxers have friends who had COVID and came through it ok. And now, trust us, take this experimental vaccine without any backup plan in case it has adverse effects lasting a couple of weeks. Loss of work, maybe a hospital bed to pay for, etc.
The vaccine would better tolerated with a national health care plan and letting people take Ivermectin if they want it. At the moment, CVS won't fill a Ivermectin prescription, even though it quite safe, but they will fill up your pain pills no problem. I do think that the vaccine is marvelous, but I'm not naive to the failings of our medical system.
sure, theres a lack of vaccines in undeveloped country and this coukd be a stop gap, but so could vitamin D. Theres no reality where i take ivermictin today and 6 months from now im protected. most vaccines for mostm people, that is the routine and normal expectations.
its a medical curiousity and so is vitamin D, but this false idea that its going to some how displace vaccines is antivaxx wishfulfillment. wake up, antivax is a viral meme bourne by ignorant and transmissible by people who view science through obtuse political lenses and no drug will penetrate that viscious type of stupidity because its spreas by super spreaders like russia, american theology and republican monied interest.
the real viral threat is the meme and ivermictan wont stop that either. people arnt antimask because theres a vaccine.
