Thanks for reading and commenting.
First, it's true that they don't check after two months. But no signs of tissue damage were found at 2-month, making the hypothesis that long-term tissue damage very unlikely. If the vaccine is toxic, we should see its toxicity soon (within a few weeks). And there is no mechanism to explain delayed onset toxicity of vaccines.
Second, the article Dr. McCullough tweeted refers to an anecdote, not a scientific study. If we want to rely on anecdotes, then I can say I got three vaccine shots and I'm perfectly fine.
Third, I've heard about the Japanese biodistribution study and have written about it (link below). For one, the study injected the vaccine into the rats at about 18-35-times higher doses than what is typically used in humans. Second, only <0.1% of the vaccine is found in off-target sites, like the ovaries, heart, etc., a negligible amount (I highlighted these numbers in the link below). And no evidence of tissue toxicity was found.
So, the Japanese biodistribution findings are by no means shocking, but some people just make it seem so.
