After some events within our family in the past few years, we began researching vaccines and finally came to the conclusion that we just could not get the right information to be able to safely vaccinate children. My cousin, who was a healthy 17 year old girl before her MMR booster vaccine, somehow "spontaneously" developed an inability to produce her own red blood cells two weeks after the vaccine and will now have to be on medication the rest of her left to help her body continue to make blood. When my aunt strongly urged the doctor to report the issue as a vaccine reaction, he refused because he said there was no proof and that the problem just "happened". So when people say there's no proof of the vaccine reactions...it strongly looks like those reactions are being ignored, not reported and certainly not studied properly.
