Sometimes the truth just needs to be said, and sometimes it is said so well that nothing needs to be added.
From the blog Denialism:
Who has the moral high ground in the vaccination wars?
My initial response is that I do, "I" meaning the medical and public health fields---those of us who prevent disease, disability, and death.
But it's much more complicated. Many anti-vaccine activists are "true believers". They really believe that vaccines do more harm than good. But, without getting all Godwin, being a true believer doesn't insulate one from moral responsibility.
Those of us who are professionals have made the evidence available. The science is clear---vaccination is a good thing, and more important, it is better than the alternative. True believers will never be convinced by something as simple as truth.
On the front lines, though, are individual parents. They make good or bad decisions based on available information, propaganda and otherwise. The anti-vaccination cults are very effective at communicating lies to these parents, interfering with their ability to make good decisions. It is the equivalent of telling people "water purification is bad. It interferes to our individual rights, and you shouldn't do it. I keeps us from being exposed to vital immune boosters." This leaves individuals wondering what to believe, and the often try to pick the "safest" choice.
In the case of vaccines, this often means that parents chose not to vaccinate. (I don't have statistics on this, but the resurgence of vaccine-preventable illnesses points in this direction.)
