We can't say that! It's getting thrown back at us. We're not saying that it's causal, we're not even trying to propose mechanisms. All we're saying is that using government reported data, we see a signal that suggests that certain adverse events are time and location correlated with vaccine roll outs. Could there be other explanations, sure!
Our successful tack has been to take all mention of the vaccine out of it and just report our organized data (organizing government data is always fun) and just publish a paper of data without even suggesting hypotheses to follow up on (doesn't feel like real science to us).
Once that paper gets in the literature, then we can write a second paper referencing that, and go on from there. It's all a political game...that's delaying good science that can save people's lives!
So my guess with this paper is that they have data, they've thought of the vaccine as an issue. But they have to go with a more politically correct reason to get the data out in the open and then they can follow up later once their data is in the literature.
Edit: why the down votes! I'm not saying that it IS the vaccine, I'm saying that it might be and we should study it. But this does show that once you bring up that idea, the censors come out of the woodwork. So frustrating! When politics stop the questions you can ask, we have serious problems.
