There’s another book I read which I can’t remember right now. It explained that they diagnose diseases based on vaccination status. For example, there was one disease they’d label as measles I think if you’re unvaccinated. But if you get the same symptoms and are vaccinated, they just call it a different disease. I read this book maybe 5 years ago. It’s hard to develop a complete and accurate narrative of everything going on when the data is unreliable.
