There is no direct link between vaccinations and autism. This has been shown in at least 7 different studies since 2007. In fact, in places like the UK, Denmark, and some other countries where Mercury was cut out of vaccinations before the USA, autism rates continue to climb as vaccination rates remain constant.
The closest direct link thus far, that I have seen, is gestational diabetes with the mothers in the first and second trimesters. These mothers have a significant increase in the chances of having a child with autism.
I will admit that I have two doctors in my family and two nurses, one in pediatrics; and they go crazy mad when uneducated people make claims about a link between vaccinations and autism. The proof is just not there. My kids and grand kids have all had their vaccinations
Significant research is underway….the, autism rates continue to climb even as the rates of vaccination remain constant. If you are concerned, donate to Autismspeaks. They are a world-wide organization doing good work.
