the network for radical unschooling families
When my kids were little, I read anti-vaccination materials and decided against vaccinating them. I weighed the likelihood that they'd be exposed to the various diseases with their living environment (modern plumbing, healthcare, breastfed, non-day care etc) and chose to delay all vaccs. reassessing as they grew older. The one thing I didn't do, that I regret now, was study up on some of the more common communicable diseases that most of our society do get vaccs for. When my kids were 12 and 6 they both came down with Pertussis but we didn't know what was wrong with them for a long time. They were very sick with coughing for six weeks.
I took them to the doctor almost weekly. They saw multiple physicians, had x-rays, were put on antibiotics and steroids but none of the doctors we saw could diagnose them properly until we took our oldest to a specialist, a pediatric pulmonologist, and while there or younger child exhibited the classic whoop of a cough. Mystery solved.
I was very frustrated with myself for not being more informed about the diseases that are routinely vaccinated against. My kids were fine in the long run and will probably have a life-long immunity to Pertussis that the vaccines do not offer -- but we exposed a lot of people unknowingly and my kids suffered a long time unnecessarily. Our county health department was involved as was our local school district because my older child had been participating in the school band. It was a little embarrassing to me. So, my advice is to educate yourself about your choices.
My kids have now received some (but not all) of the recommended vaccinations but before they did, I studied up on each of the diseases and their vaccs. My now 18 year old son decided to have a couple more vaccinations recently. I shared what I knew with him and he made the choice. Unschooled kids needn't wait until they're 18 to make these kinds of decisions for themselves but it just hadn't come up until then, for my son.
