http://www.jennymccarthybodycount.com/Anti-Vaccine_Body_Count/Home.html First of all, it is not right to blame only McCarthy for the rise of anti-vaccination movement in the US, but it is undeniable that she played a huge role in using her public image to propagate pseudo-science and sway the opinion of the gullible towards anti-vaccine. The rise in outbreaks of measles and whooping cough is of a real concern, thanks to the role played by parents in opting their children out of vaccinations. This is a neat infograph that speaks for itself: Here is the link to an article detailing the rise of pertussis in Vermont and how the anti-vaccination movement is getting more powerful by the day. http://www.slate.com/articles/healt...axxer_activists_stopped_a_vaccine.single.html On a personal note, I grew up in the third world and saw how people suffered first hand due to not being vaccinated. Just because people here in the US haven't experienced these.. that doesn't mean the reality of danger isn't there. It is deeply concerning that people who have cognitive bias are the ones who tend to be more vocal and they generally try to be willfully ignorant of facts that contradict them.
