I Have A Friend Who's Anti-vax (not Me, I Had

I have a friend who's anti-vax (not me, i had rabies so im 100% for it). is there any sort of link that shows the parents who didn't vax and ended up getting bitten in the ass for it? like, i need something hard and heart felt to get through to this person. they are very stubborn and too locked into a false mindset. ive already said its to help with the rest of the herd, not killing babies or old people, even argued that a possible autistic kid is better than a dead one. even claimed its more harmful to drink water or eat food without washing your hands in comparison to the toxins in the vaccinations. please, i don't wanna get attached to their kids because i feel they are a temporary thing because of this.
