I was personally affected by a hot batch when I was younger, and have had subsequent reactions to other vaccines since.
This idea that herd immunity is some moral issue, on which we owe it to the social stucture is bull. Do people have reactions and die from these vaccines? Yes.
How are these vaccines regulated? and tested on children espeically those under one year? Not very well.
The moral issue here is not if you vaccinate your children, it really comes down to if we as a "society" accept that fact that we will kill children as an accepted risk to stop other diseases, and if that we as a "society" will allow a government to force a vaccination into our bodies and into our children.
I personally won't accept this, if this means my children not participating in public education then so be it. But to say that your immoral, or to say that your "killing" others; and treat you as if that is the case. That is sensationalist bullshit.
