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.
I agree. I would always consider supplements, vitamins, herbal remedies if possible. One child in our area was given polio serum and the baby contact polio and later died of it. It can be very dangerous.
