Here’s a couple of fact checker refutations of the dodgy speculations about vaccine cytotoxicity in that video featuring Weinstein, Malone and Kirsch:
“Fact Check-COVID-19 vaccines are not ‘cytotoxic’
Posts are sharing the false statement that the spike protein in COVID-19 vaccines is cytotoxic, suggesting that it kills or damages cells. There is no evidence to support this.
[ … ] VERDICT
False. There is no evidence that COVID-19 vaccines are cytotoxic (toxic to cells).”
“No sign that the COVID-19 vaccines’ spike protein is toxic or ‘cytotoxic’
[ … ] Bret Weinstein, who is identified in the video as an evolutionary biologist, is the one who says the spike protein in the vaccines “is very dangerous, it’s cytotoxic.”
Dr. Robert Malone, identified in the video as the inventor of mRNA vaccine technology, said he sent “manuscripts” months ago to the U.S. Food and Drug Administration claiming the spike protein posed a health risk. “And their determination was that they didn’t think that that was sufficient documentation of the risk that the spike was biologically active,” he said.
The third person in the video is identified as “serial entrepreneur” Steve Kirsch, who said he is an engineer. He cited a claim by Canadian viral immunologist Byram Bridle that the vaccine doesn’t stay in the shoulder, where it’s injected, but “goes throughout your entire body, it goes to your brain to your heart.”
Bridle’s claim: False
We rated False Bridle’s claim that the COVID-19 vaccines’ spike protein means people are being inoculated “with a toxin.”
Experts told PolitiFact there is no evidence to back his allegation that the spike protein produces a toxin that could cause serious health problems.”
Of course a diehard conspiracy theorist won’t take any heed of fact checker sites – “facts? who needs ’em?” – but the scientific sources for their verdicts are fully declared, so you can take it up with the scientists.
