I'm with the doctors. Not vaccinating your children does not affect only your child, it affects every child yours comes into contact with. Areas with high rates of non-vaccinated children also show significantly higher rates of diseases like measles among young people.
I have no sympathy for any parent who doesn't vaccinate their child. I feel terrible for the children, since it's not their choice, but any parent dumb enough to fall onto the "Vaccines cause autism!" bullshit bandwagon deserves to be shunned by their doctors.
