There is no connection between autism and vaccinations. None. It has been proven over and over. There is a very real risk from people not vaccinating their children. Check out some videos of kids with pertussis. It will make your hair stand on end.
I agree with the other comments. Autism has been found to have genetic links. It is also found more often in the children of older parents. And, it is often found where there are extra benefits provided for autistic children, as opposed to kids with other mental issues or retardation. Doctors know that more resources are available to autistic kids, so they have a tendency to use that diagnosis to help out the parents in getting more help.
You mentioned genetics. Very lkely some are more susceptible than others for just this reason.
I have no kids and I survived my childhood but these days, I am still suspicious of over ‘doctoring’.. and your point on docs misdiagnosing to assist the parents get help elsewhere is a good point.
How many different vaccines are kids subjected too these days before they hit 6? How recent are those studies?
The vaccine theory may not be totally discounted. Gulf War Syndrome where troops got sick with many different symptoms may have been caused by too many vaccines taken at the same time. The mercury preservatives may not be the problem but the side reactions interacting with each other. From birth to kindergarden children must take many vaccines.
Tibit info, Amish do not eat processed foods, and take immunization shots, their autism rate is 1 per 15000 while nearby non Amish neighbors have autism rate of 1 per 150.
