Vaccines have been a hot topic for years when it comes to the risk of Autism. Many moms are very concerned about this issue. Many moms ask me about the connection and the risks. This is not my field of specialty but they want to hear what we did with our 6 kids.
I have always followed the European protocol for vaccination which is a slower vaccination protcol (ie: not all at once). Europeans spread out the vaccines over time more than what US pediatricians recommend in my experience. All our kids got all their vaccines but we did it more slowly. When I got a push back from a pediatrician a couple of times, I pulled out the studies showing the European way and the fact that giving vaccines over time instead of cramming them in all in the first years seems to be acceptable (as long as they are not immunocompromised or have other risk factors.
I for one deferred the Hepatitis B vaccine as I did not get mine till medical school. When I was growing up, it was not offered.
Is the concern over vaccines and autism valid? I think it is. There is a great deal we do not know.
The below 2 studies point to Aluminum in some vaccines that may be a concern. These studies do not say “don’t vaccinate your children.” But they point to something that needs to be investigated further.
Do aluminum vaccine adjuvants contribute to the rising prevalence of autism?

Autism spectrum disorder (ASD) is a group of neurodevelopmental conditions of unknown cause. It is highly likely that both genetic 
and environmental factors are associated with the onset and progress of ASD while the mechanisms underlying its aetiology are expected to be multifactorial 
, . Humanexposure to aluminium has been implicated in ASD with conclusions being equivocal 
, . To-date the majority of studies have used hair as their indicator of human exposure to aluminium while aluminium in blood and urinehave also been used to a much more limited extent. Paediatric vaccines that include an aluminium adjuvant are an indirect measure of infant exposure to aluminium and their burgeoning use has been directly correlated with increasing prevalence of ASD . Animal models of ASD continue to support a connection with aluminium and to aluminium adjuvants used in human vaccinations in particular . Hitherto there are no previous reports of aluminium in brain tissuefrom donors who died with a diagnosis of ASD. We have measured aluminium in brain tissue in autism and identified the location of aluminium in these tissues.
