When Older Sib Has Autism, Vax Rates Drop

Families with children with autism spectrum disorder are less likely to vaccinate subsequent children, and more likely to cite adverse effects from vaccines, researchers found.
Writing in the Correspondence section of the New England Journal of Medicine, researchers in California found the rate of vaccination was lower among children who had an older sibling with autism spectrum disorder than it was among "low-risk infants." Moreover, the authors found a higher portion of parents reporting adverse reactions to vaccines for both their child with autism and the infant sibling compared to those parents who did not have an older child with autism.
