When did inoculating children begin? That would be an interesting area to examine. Also, Amish don't inoculate their children, do they? They don't go to doctors. I've seen them in my nutritionist's office. They trust him for their health. Interesting.
At least by the time Ben Franklin had kids; he lost one four-year-old boy to smallpox and regretted not having vaccinated him. He may be part of the reason that form of "immunizing" has so much social acceptance, along with many of his other "reforms."
I would encourage anyone interested in the topic to compare the use and effectiveness of homeopathic nosodes instead of conventional vaccinations; the difference can be likened to stimulating the immune system as opposed to overwhelming it. The proven consequence of overwhelming the human immune system by inoculation (which bypasses the protective function of the gut) explains the sequelae (following incidence) of disease conditions after inoculation mentioned by one poster to this thread.
