Children of Anti Vaxxers Don't Get Autism Because it's never diagnosed before the age of two.
I don't know if you are joking or not.  Are you saying that anti-vaxxer's children should face the death penalty?
I am joking. Actually I just wanted to post something funny, though it wasn't all a joke
It seems like you want to prevent children from dying from preventable diseases, and this is a laudable goal.  However, the way you said it as a joke trivializes the real harm that falls on children whose parents refuse to vaccinate them against deadly diseases, and this can be distressing to everyone.  The loss of a child is not acceptable as a punishment for anyone, regardless of their actions.
