There's no conclusive link between vaccines and autism. There is however a link between autism and children who live in heavily industrialized areas. A study was done out in California in a heavily industrialized area after many children living around the area developed autism. The conclusion was that where a child lived may play a role in the development of autism.

Another key note I took of this study was home schooled vs non home schooled children. There's a economic factor that would lay heavy among that analysis which I don't see displayed here. Home schooled children are more prone to come from middle to higher income better educated households who don't live in heavily industrialized or older housing where lead and older industrialized area's were once common.

Then there's also no mention of the role that plastics has played since the increase of autism cases. There's quite a bit of evidence coming forth showing that infertility among younger adults today may be linked to the heavy use of plastics in todays society. There are more than likely many other links to health issues when it comes to plastics but plastics are made from oil and linked to millions of jobs globally....that's the real precursor as to why no one's willing to look into the adverse health issues faced by many people today. If you want to find a true culprit to blame vaccines, in my opinion, would be low man on the totem pole compared to the use of plastics that are in virtually everything we touch now a days. It isn't even everything we touch either it's what's inhaled out into the air. Many of our clothes are now made with synthetic plastics, these micro particles are washed off into our waterways and blown off into the air from drying our clothes....there's a much more reasonable reason to believe that if there is more allergies and asthma now a days that it once again would stand a greater chance to be linked to plastics than any vaccine.
