Do you remember, GB, when we went to kindergarten we had to produce our Immunization Card? At least, in Canada we had to. We weren't allowed in unless it was uptodate. And then, we got shots by the nurse in school (smallpox, for one). There was no option. You either got a vaccine or you were home-schooled. I was too young to know if there was an outcry, but I highly doubt it.
And some cities, Vancouver, for example, wound up fluorinating their water. No choice in the matter.
My mother was deathly scared that we'd get polio, such a debilitating disease, that we were definitely getting that DPT shot. And I hear that measles is on the rise in many countries. And I also heard that the measles vaccine is only about 50% effective in not contracting it, but it sure made a difference if you got it.
