Some of the old diseases that we think are gone - case in point, measles - are back, now that somebody has spread around, in a very wicked way, the idea that these inoculations were making children autistic. Now we're getting outbreaks that are killing children. The end result is, if you create a population that lacks immunity, and diseases are still there, you're going to get outbreaks and you're going to get death.
Margaret Atwood
