Nicholas, if everybody made the choice not to vaccinate, endemic diseases that used to ravage populations still would be with us. The only reason you have the luxury of focusing on vaccine risk is because everybody else has created a herd immunity that benefits you too. I'm afraid that what you and your friends effectively are saying is that your preference is to rely on everybody else to taking the risk you perceive so that you don't have to.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
