Shedding is one of the funniest tropes spun by antivaxxers. It was promulgated by Pierre Kory, who had one patient claim that she had imbibed the Mrna spiked protein while giving a BJ to her husband. Of course, Kory immediately set out to create a course of treatment. Last I read, he was charging over $2000 for a series of 3 online appointments to treat not just Covid, but what he calls "long vax" (because of course he doesn't believe in long covid), and vaccine injuries. None of his treatments have been subjected to random-controlled trials of course but that doesn't matter because he knows they work. Look how much money he's making after all.
Kory was the first proponents of Ivermectin, citing an Argentine study that found 100 percent efficacy when Ivermectin was taken as a prophylactic. The study turned out to be, if not outright fraudulent, riddled with errors and fake data. Kory himself ended up getting Covid 19, as did Bret Weinstein, who had gone on Joe Rogan to tout the benefits of Ivermectin based on Kory's recommendation.
Kory was one of the founders of the FLCC, and was making over $300,000 a year until he quit because his private Covid practice had become so lucrative. He's just one of the many antivaxxers who has become rich through his antivax activities while at the same time attacking big pharma for their lack of ethics and focus on profits.
