I believe there are safer, more effective alternatives that are simply disallowed. All they do is say "Nope, not good enough" to anything that is not vaccines. And that alone is enough to make me believe the vaccines are dangerous and ineffective.
As for me, I got the Amazon "shot" in May 2020. That is when my first bottles of quercetin arrived, and I started taking it then. Now, this does require a "booster" dose per day, but of a nutrient that is only going to help those who take it. This stuff works like the hydroxychloroquine that was banned in 2020 because it competed with the remdesivir (worthless and quite dangerous, best reserved for cases where even the quercetin and then ivermectin aren't enough) and the mandatory vaccines.
As for long term dangers? I suppose that, one day, I might choke on a quercetin pill and die from that. But at least I will not be getting blood clots, auto-immune diseases, cancer, strokes, heart failure, blindness, deafness, and severe fatigue from it. And I know quercetin works against all variants, from the original SARS and MERS, to whatever Chinese letter they finally end up with for variants.
Too bad it is not good enough for those jokehovian witlesses when they re-open the buildings for in-person boasting sessions and field circus. They are going to insist on a real shot, not the Amazon "shot".
