Why not have half the participants "unvaxxed" and the other "vaxxed"?  What the studies fail to prove is the difference between the two and also maybe figuring out the actual demographic of those who die from the virus?  They were looking for it in the beginning of the virus and just stopped like the mRNA was actually going to stop the virus. Now these are all studies on which spike protein is best at exacerbating your immune system the right way to be ready in case you do catch the virus.  Even though you call it a vaccine it will always be a manipulation of DNA.  How producing spike protein is supposed to combat spike protein is beyond my realm of thought because it's still spike protein  and now you produce it yourself without an off switch or any knowledge of what else it may be doing.  Unless I woke up in an alternate reality that kind of research was seen as immoral by most of the us population.  It was taboo enough that it was illegal along with stem cell research.  Humanized mice is still not a human and that's the only human anything it was tested on before roll out.  No amount of research on which will kill you faster will ever make people want to willingly get a shot if they haven't already just fyi. If they were actually being scientific on this subject they would be scrutinizing every little piece of data no matter how small or insignificant or how dangerous it might be.
