Maybe it’s my peer group but no one knows that vaccines have had a past. They don’t know vaccines aren’t some magic liquid that falls down for every virus. Of course we should use them, most medication have had to hurt some to help more. Also I personally understand the toxic metal mercury thing. I know it doesn’t cause autism, but look it up on google and go to images. You can see how young mothers are convinced. Especially since most people don’t do any research on vaccines but believe they are purely good. You can see how mothers that do just a little bit more research than the normal person might feel enlightened and not vaccinate.
