Parents may be skeptical when it comes to vaccinations, especially if they already have a child diagnosed with autism spectrum disorder (ASD). A study published in the Journal of the American Medical Association has found no link between the measles-mumps-rubella (MMR) vaccine and increased risk of ASD. The study evaluated the insurance claims of about 96,000 children who received the MMR vaccine and were born between 2001 and 2007. The children included also had an older sibling with or without ASD. From this population, researchers recorded that 1.04% of the children were diagnosed with ASD and 2.01% had an older sibling with ASD. In the group of children whose older siblings were diagnosed with ASD, about 7% had ASD. On the other hand, 0.9% of children whose older siblings did not have ASD were diagnosed with the disorder. Researchers determined that MMR vaccine was not linked to a higher risk of ASD at any age. Furthermore, the children who received one or two doses of MMR vaccine whose older siblings had ASD were not at a higher risk of being diagnosed with ASD. What are your thoughts of this finding? How often do you counsel parents about concerns of vaccinations?
