If you are an "anti-vaxxer" you have probably heard of this woman, Dorit Reiss. She is one of those folks who wants to deny families any choice over what gets injected into their children. This is presented not as a matter of human freedom or recognition of the role of parents in determining the interventions given to their children, but as a common sense demand to protect others/community.
I strongly believe anyone denying informed consent for vaccination has an agenda to weaken and control others.
