A recent study published in The Journal of Pediatrics disproves the speculated association between vaccination during a child’s first two years and developmental disabilities. The research was performed as a case-control study drawing its population from three managed care organizations with a total of 256 children with autism spectrum disorder (ASD). The children ranged in age from 6-13 and all ASD diagnoses were confirmed by the researchers. Additionally, researchers took precautions to ensure that the control group did not include children with undiagnosed ASD, using the Lifetime form of the Social Communication Questionnaire (SCQ). Children with medical conditions related to ASD (fragile X syndrome, tuberous sclerosis, etc.) were excluded from the study. Variation in exposure to antibody-stimulating proteins and polysaccharides from vaccination was measured from medical records and immunization registries. The wide array of vaccines available rendered a significant variety of antigen levels among the study population, but the findings did not support a correlation between increased exposure to antigens in the first two years of life and ASD outcomes. Eliminating another potential cause of autism spectrum disorders is a promising step towards identifying causes and preventing onset in the future.
