Think about what 9 or more adjuvants do to an infants immune system.

ad·ju·vant (j-vnt)
n.
1. A pharmacological agent added to a drug to increase or aid its effect.
2. An immunological agent that increases the antigenic response.
Although there is no evidence that adjuvants might create a risk, maybe we should be extra safe and test if they are a problem as currently used. Oh wait, the National Academies just did that test. Good news-they are safe just as we thought!
By the way, I know you like the strawman of 9 vaccinations at a time, but that is not the current recommendation nor is it in common use. Therefore it certainly can't be the cause for the increase in autism diagnoses you are concerned about.
