First of all 90% of what you read on the internet is wrong, some of it is mis-informed some of it is out right lies. There has not been a single scientific paper ever to show any link between autism and vaccinations.
However in almost every case where vaccination rates drop if the virus or bacteria is still in the environment outbreaks happen!
If you think that vaccinations are a scam aimed at hurting children ask yourself this question… how many children do you know who have been killed recently by Measles, Mumps, Polio, Whooping cough, Diphtheria or Smallpox? For most people reading this that number will be 0, if we had been somehow having this conversation in 1911 and not 2011 It would have been MUCH higher.
My father is a micro-biologist and he recommends anyone who works in public health should take a walk threw a grave yard from the 19th century to see all the graves of children and know exactly why public health is such an important field of work.
(My grandfather had Diptheria in his youth, he missed a year of school because of it, thankfully he survived and lived to be 99 years old)
