The Nebraska Infectious Diseases Society (NIDS) strongly affirms that extensive, rigorous, and established scientific evidence shows that vaccines do not cause autism. This conclusion is shared across other professional medical and scientific societies, including the Pediatric Infectious Diseases Society ( pids.org ), the Infectious Diseases Society of America ( idsociety.org ), the American Academy of Pediatrics ( AAP.org ), and the American Medical Association ( ama-assn.org ), all of which have released similar statements. On November 19, 2025, content on the CDC web page entitled “Autism and Vaccines” was altered to include misleading and scientifically unfounded claims about vaccines and autism. Although the Secretary of the Department of Health and Human Services (who oversees the CDC) promised during his confirmation hearing not to alter the statement “Vaccines do not cause autism” on the CDC website, the revised content now implies the opposite despite “technically” not altering this original phrase. Furthermore, these changes were made without the input of CDC scientific and professional staff. This messaging is dangerous and undermines scientific integrity, erodes public trust, and places parents in an unfair and confusing position. Ultimately, such information will lead more people to question life-saving vaccines, resulting in more cases of vaccine-preventable diseases, more outbreaks, more severe illnesses, and more preventable deaths. NIDS stands firmly with the broader medical and scientific community in reassuring parents and caregivers that routine immunizations remain among the safest and most effective tools to keep children healthy. Vaccination is also one of the most powerful ways we, as a community, protect one another—especially those who are too young or medically unable to be vaccinated. By staying up-to-date on recommended vaccines, families help safeguard not only their own children but the health and well-being of our entire community. Vaccines do not cause autism. Families deserve honesty, clarity, and support – not confusion fueled by misinformation.

Vaccines Do Not Cause Autism

Chief, Division of Infectious Diseases University of Nebraska Medical Center What brought you to Nebraska?  I came to Nebraska for the opportunity to lead an excellent ID Division at UNMC/Nebraska Medicine. There are many strengths of the program, including faculty who are recognized leaders in HIV care, infection prevention, antimicrobial stewardship, immunocompromised ID, and biopreparedness, just to name a few. The Division has developed innovative programs around remote care of ID patients and supporting infection prevention and antimicrobial stewardship in rural areas of the state, which have served as models nationally. Given the challenges faced by the field of infectious diseases, how do you plan on leading your division to address these changes? There are many challenges that face infectious diseases specialists today – a loss of trust in public health by the public, misinformation about infectious diseases on social media, and an unstable funding environment for biomedical research and programs which support the care of vulnerable individuals. This is in the face of increasing antimicrobial resistance and the re-emergence of vaccine-preventable diseases, such as measles. It is easy to become discouraged. My plan for the Division is to continue to “lead by example” by providing excellent care to the patients that we serve, particularly patients who from groups that are marginalized in society. I will support the research and educational missions that are core to the Division. Infectious Diseases specialists have always been advocates, but in the current environment, it is needed more than ever. I want to encourage the faculty to educate their patients, the public, and policymakers on evidence-based treatment and prevention strategies for infectious diseases. If we are silent, there are many individuals who will fill the void with misinformation. What would you like to see NIDS do to help support infectious diseases work in the state of Nebraska? I would like to see NIDS take an active role in education and outreach to the public and policymakers in Nebraska. Having a dialogue with these groups, addressing their concerns and informing them about the risks of infectious diseases and what is needed to treat and prevent them, is critical to rebuilding the trust that has been lost in the time since the COVID-19 pandemic. What is a fun fact about yourself? I love hiking. I am a day hiker but would love to try longer hikes. Some of my favorite hikes have been the “Oh-Be-Joyful” trail in the Gunnison National Forest in Colorado, and Johnston Canyon Trail in Banff National Park. Since I arrived in Nebraska in January, I have hiked several trails around Omaha with my wife and our black and tan coonhound, Reggie. I am looking forward to exploring the Sandhills.
