If your kids are immunised then they're protected, right? Unless this is a subconscious concession that immunisation isn't the protection it's sprouted as being... What then?
This is really basic stuff, immunisations are only effective if almost everyone gets immunised. This is what I'm trying to say, its an important point.

I have lain my life and the lives of my precious children at the feet of our (somewhat flawed admittedly) immunisation schedule in the knowledge that it might kill me or them in order to increase their chances of surviving and living long productive lives and to help other people get the same chance. That is what immunisation is about, thats what society is about, THESE are decisions we make.

But people don't understand these things, they just don't want their kids to get sick.
