Autism is a form of brain damage. The info in post 60 which BTW is the US Center for Disease Control list even Moderate side effects as following
Moderate Problems
Seizure (jerking or staring) caused by fever (about 1 out of 3,000 doses)
Temporary pain and stiffness in the joints, mostly in teenage or adult women (up to 1 out of 4)
Temporary low platelet count, which can cause a bleeding disorder (about 1 out of 30,000 doses)
Seizures??? Nah nothing go on in the brain no sir indeed. /sarcasm Oh and the next paragraph on the MMR information
Severe Problems (Very Rare)
Serious allergic reaction (less than 1 out of a million doses)
Several other severe problems have been reported after a child gets MMR vaccine, including:
Deafness
Long-term seizures, coma, or lowered consciousness
Permanent brain damage
These are so rare that it is hard to tell whether they are caused by the vaccine.
Sroll to bottom for "Page last updated: August 19, 2014"
In other words not even the CDC is certain YET!!!!!! that they don't cause it.
Wakefield Article Linking MMR Vaccine and Autism Was Fraudulent
Most people quit parroting narratives when they're disproven, but you seem to want to double down.
