Yes, but it's your child who gets polio or post-viral encephalitis (a complication of measles) - not you. That's kind of like saying that if you leave a loaded handgun out and your child shoots and kills himself, you are to blame.

I'm not saying I'm for the overabundance of vaccines that are out these days, but if everyone stopped vaccinating their kids we would take a step backwards with regards to health care.
