No it doesn’t, he states clearly (in both articles) that this is his theory not a fact, and in the second article presents a study that lends credence to the theory.
He uses the word “suggests”, as in it is possible or plausible.
The only way we could know this “for a fact” is to do autopsies on covid deaths, but it seems, after a year and a half, there seems to be no real urgency to finding out what covid (or the vaccine) are doing to the human body. I guess there’s no money in that when you can make millions off a “vax”
The companies would make more…and lives would be saved if the government paid for insulin.
