I’ve never seen Franklin brought into the discussion of parents’ refusal to vaccinate their children. This passage from his autobiography made a deep impression on me:
In 1736 I lost one of my sons, a fine boy of four years old, by the small-pox, taken in the common way. I long regretted bitterly, and still regret that I had not given it to him by inoculation. This I mention for the sake of parents who omit that operation, on the supposition that they should never forgive themselves if a child died under it; my example showing that the regret may be the same either way, and that, therefore, the safer should be chosen.

I once was at a parents’ meeting in Oxford where a homeopath had been invited to speak. I was genuinely nonplussed that she was raving against vaccines. Aren’t vaccines the one great success of the homeopathic world-view? Giving a tiny dose of the disease-causing agent to cure (or prevent) the disease. Her answer was incomprehensible to me, but seemed to suggest that the very fact that there was a measurable physiologic effect showed that they weren’t any good (from a homeopathic perspective). And the fact that pharmaceutical firms made the vaccines was all you needed to know about their chthonic nature.
I fled the meeting in revulsion when the homeopath started prating about homeopathic cures for tetanus.
