According to the article, the people were given information that basically said. "You can't prove autism is from vaccinations" and the rest was scare tactics. Photos of kids suffering from the afflictions the vaccines purport to prevent.
How is this any different than the religious argument?
You can't prove God doesn't exist. This is what happens in hell.
My body belongs to me. You shouldn't worry if I don't get vaccinated if you have been vaccinated... Right? You shouldn't worry if my child hasn't been vaccinated if your child has been vaccinated... Right?
