I'm sure the viruses and toxins in vaccines contribute to cancer, but the other issue here is that harmless childhood illness like measles and chicken pox are being found to provide protection against cancer. There was a study not too long ago that showed kids who got chicken pox were protected from the worst of brain cancers. Well.... now that we vaccinate, guess what is on the rise? Deadly brain tumors. I don't think I go a week without seeing someone posting in my FB feed about another kid with DIPG. This is a fatal "Extremely rare" tumor. Well... they need to do the math because it's not rare anymore.
