How do you think we can get through to the anti-vaxxers?
Unfortunately, I don't think anything will get through to them until their kids and loved ones start dying from very old and highly preventable diseases.
Their mindset is one much like the followers of creationism, etc where they believe that:
1) All scientists have been bought out by "big pharma" or
2) That the consensus among the scientific community is some kind of organized ploy to sell more and more drugs.
Because of this, no matter what scientists or public health officials say, they just plug their ears and go "LALALALALA".
