You can't assign any and all medical issues to vaccines and expect that to be legit. That's retarded. With huge swathes of the populations getting vaccinated, the probability of any illness popping up even a day after getting vaccinated is quite high. With tens of millions of illnesses popping up each year, the probability that ANYONE will have a medical issue within one hour of being vaccinated is huge. Every hour, about 132,800 people will have a medical issue in the US. That's EVERY hour. Disease, illness, acute medical situations, etc. Every hour. Finding someone who just got any vaccine in that hour is far greater than 100. So how do you figure out if the vaccine caused the medical issue? Controlled research. Which has been done already.
