The American Academy of Pediatrics estimates that one out of 10 parents delays or refuses vaccines for their children because of concerns about the growing autism crisis in young children. While parents fears are certainly understandable as autism rates have recently climbed epidemic proportions –particularly in young boys—medical experts continue to maintain there’s no credence to fears that vaccines somehow trigger the disorder. Indeed, a new study recently reported in the journal Pediatrics, says there’s also no proof to the “too much too soon” theory, which suggests that giving young children multiple vaccines in close proximity is harmful.
The study, conducted by researchers at the federal CDC in collaboration with Abt Associates, looked at more than 1000 toddlers with and without autism diagnosis. It sought to determine whether the presence of antigens following vaccination could somehow be associated with causing autism spectrum disorder. According to the authors, “The possibility that immunological stimulation from vaccines during the first one to two years of life could be related to the development of ASD is not well-supported by what is known about the neurobiology of ASDs.” In 2004, a comprehensive review by the Institute of Medicine concluded there is not a causal relationship between certain vaccine types and autism and this study supports that conclusion
The study was accompanied by a strongly worded editorial with AAP implying it’s perilous for parents to postpone vaccinating their children because of these unfounded concerns.
