Anyone notice any regression in their child ALREADY DIAGNOSED with SPD after the MMR vaccine?

I didn't notice any different behavior before or after. However, my son did have a seizure and 105+ fever for over 24 hours after his second MMR dosage (within 1-3 days after). Of course the hospital and his Dr. refused to report the incident. The testing came back that there were no virus or bacterial infections and that the vaccine was the most likely cause of his seizure. I spaced my son's vaccinations out over months never getting more than 1 in a 2 month period. I think that helped minimize major issues as best we could.
