In the latest study on the vaccines, researchers find even more evidence that childhood immunizations aren’t linked to autism.
In a study published in the Journal of the American Medical Association, a group led by Dr. Anjali Jain of the Lewin Group, a health care consulting organization, found that brothers and sisters of children with autism were not at any higher risk of developing the disorder if they were vaccinated compared with brothers and sisters of those without autism.
Numerous studies have found an increased risk of autism among those with older siblings with the condition, and some parents who believe that their older child’s autism is connected to vaccinations, specifically the MMR vaccine, have been reluctant to immunize their younger children. Indeed, Jain found that vaccination rates among siblings of autistic children were lower, at about 86 percent at 5 years, compared with 92 percent among those without autistic brothers or sisters.
But among the 95,000 children with older siblings included in the study, children who received the MMR and had autistic older siblings were no more likely to develop autism than children who were vaccinated and didn’t have any autistic older siblings. In fact, the relative risk of autism among those with older autistic brothers or sisters was lower if they were vaccinated compared with those who were not vaccinated.
