Leading public health advocates in Wisconsin are issuing a strong statement in response to recent public remarks raising concerns about a supposed link between vaccines and autism.

“Vaccines do not cause autism,” said Dr. Betsy Peterson, president of the Wisconsin Chapter of the American Academy of Pediatrics (WIAAP), who provides immunizations for patients according to the schedule endorsed by the American Academy of Pediatrics (AAP).[1] “Vaccines are safe, effective, and keep children, families, and communities healthy. Further, there is no scientific evidence proving that acetaminophen use in pregnancy causes autism or other developmental conditions in children.”

Katie Hess, Executive Director of the Autism Society of Greater Wisconsin, agrees. “Decades of credible, scientific research have repeatedly affirmed the safety of vaccines. There is no credible evidence linking vaccines to autism.” [2] Supporting vaccination efforts among families affected by autism, her organization provides education and collaborative, sensory-friendly clinics to provide access to a calm, supportive, and inclusive vaccine experience.

Dr. Margaret Hennessy, a pediatrician and co-chair of Immunize Wisconsin, says she discusses with families in detail the decision to vaccinate their children, including questions around possible links between vaccines and autism. She has concerns about recent comments. “Disinformation from our public leaders is causing a lot of confusion and is risking the health and well-being of our children.”
