Surprisingly well edi=ucated they are. Well, I am actually more distressed than surprised. I personally know one person with a Ph.D. who does not vaccinate, but she suffered a sever allergic reactioon when she was a kid so I can't really fault her concern. Still, the fact that these educated people are overwhelmingly (80%) unwilling to change their minds given the recent measles outbreak just illustrates that there is a highly emotional aspect to their views.
To be fair, I get pretty emotional about it also, but I am willing to alter my views if given approproate and scientifically rigorous evidence.
