The government has in fact acknowledged that vaccines can cause brain damage in genetically susceptible individuals, and that this brain damage can lead to developmental regression, i.e., autism. I quoted then Director of the CDC Julie Gerberding in 2008 admitting:
Vaccines can occasionally cause fevers in kids. So if a child was immunized, got a fever, had other complications from the vaccines.
Some of the symptoms can be symptoms that have characteristics of autism.And if you’re predisposed with a mitochondrial disorder, it can certainly set off some damage.
Is this former CDC director and president of Merck's vaccine division into "pseudoscience?"
