Can you explain why an immune system response to a vaccine would increase glutamate significantly beyond the levels that would arise from normal or more severe immune functioning in response to an actual disease?

Otherwise, I'd expect there to be a far stronger correlation between autism and childhood illnesses of a rather broad spectrum, and we simply don't see that, nor are we generally able to detect evidence of previous pre-birth infections that would have triggered that level of immune response.
