Academy Press Release on Claims Linking Vaccine & Acetaminophen to Autism

FOR IMMEDIATE RELEASE:

Academy of Medicine of Cincinnati Statement on Recent Claims Linking Vaccines or Acetaminophen to Autism

Cincinnati, OH — September 24, 2025 — The Academy of Medicine of Cincinnati is aware of recent claims suggesting a link between childhood vaccines and autism, and between acetaminophen (Tylenol) use during pregnancy and autism. We recognize that these statements may raise questions and concerns among families. As a physician-led organization committed to science, patient safety, and public health, we believe it is important to respond clearly and with evidence.

Vaccines:
Extensive research over more than 20 years has shown no causal association between vaccines and autism. Vaccines remain one of the safest and most effective tools we have to prevent serious illness and save lives. Suggesting otherwise undermines confidence in immunizations and puts children and communities at risk of vaccine-preventable diseases.

Acetaminophen in Pregnancy:
Some observational studies have reported possible associations between frequent, long-term use of acetaminophen in pregnancy and autism or ADHD. However, no study has demonstrated a definitive causal link. When used as directed, acetaminophen remains the most widely recommended option for treating pain or fever during pregnancy. The Academy supports ongoing research while affirming that pregnant patients should consult their physicians to weigh benefits and risks.

Our Message:
Families deserve accurate, evidence-based information. The Academy of Medicine urges the public to rely on trusted medical sources, such as the American Academy of Pediatrics, the Centers for Disease Control and Prevention, and board-certified physicians.

We remain committed to:

• Supporting physicians in counseling patients with transparency and compassion.
• Advocating for ongoing, high-quality research into autism and other neurodevelopmental disorders.
• Promoting public trust in evidence-based medicine.

If you have questions about vaccines or medication use during pregnancy, we encourage you to speak directly with your physician.
