Statistically *most* vaccines don't work. And if you count all the failed pre-trials, it's safe to say almost all vaccines don't work. The history of grinding up diseased animals and injecting other animals/humans is a nasty history that doesn't match the pretend facts of Pharma and Public Health liars. Prior to the magic years, EVERYONE knew vaccines were at best 60-80% effective, and had dire side-effects including death. But we prefer magic thinking.
