Aim: To compare the immunological response to measles, mumps, rubella (MMR) vaccination in three groups of children, one with autism spectrum disorders (ASD), one with special educational needs (SEN) but no ASD and a third typically developing group of children. Also, to assess the immunological response to a range of antigens both to central nervous system (CNS) and other tissues in the same three groups.
Methods: A population-representative sample of children aged 9–14 years in the United Kingdom, 101 with ASD, 54 with SEN but no ASD (98 and 52, respectively, who had been vaccinated) and 90 typically developing children were tested for measles virus, antibody response to measles in serum, lymphocyte subsets and immunoglobulin classes and subclasses, autoantibodies to muscle, kidney, liver etc and antibodies to CNS structures, myelin basic protein, actin, tubulin, basal ganglia and non-specific CNS antigens on slices of mouse brain.
Results: The results were analyzed as total ASD versus total combined control groups (SEN plus typically developing), as narrow autism versus ASD versus SEN versus typically developing and within ASD as regression and no regression. In those vaccinated with MMR, no …
