I have heard these stories a thousand times. I am a board‑certified pediatrician with 46 years of clinical experience. I’ve practiced in group and solo settings, served as Director of Pediatric Education for a residency program, and received numerous awards for child‑health initiatives. My solo practice had 3,500 general pediatric patients. I spent five years as Medical Director of the Autism Research Institute.
By caring for and consulting on more than 600 children with autism from 5 countries and 20 states, and hundreds of children with complex chronic illnesses, I have a unique clinical perspective to share, which mirrors what these families shared today.
My concerns about vaccine safety began in 1999 after my patient experienced a severe and irreversible reaction following a vaccine I gave. Despite exhaustive efforts to identify another cause, I could not. The trajectory of my career changed. I left a secure academic position I loved and opened a solo practice dedicated to children whose medical needs were not being met.
During my career I learned an extraordinary amount from parents who are usually perceptive observers of their children’s health. At ARI we partnered with families to identify medical problems that were overlooked. Their insights guided our research and these actions should guide our actions today. Families directed us to treat gastrointestinal dysfunction, immune dysregulation, and impairments in detoxification pathways. Collaborations with international scientists helped identify mitochondrial dysfunction, methylation abnormalities, cerebral folate deficiency, and prolonged cell danger responses.
Most pediatricians do not know about these issues. Addressing these problems often resulted in measurable improvements in autism symptoms. Some children initially diagnosed with moderate to severe autism entered kindergarten no longer meeting criteria for autism because their medical problems were treated. Other severely affected children treated as toddlers have gone on to college without knowing they once carried an autism diagnosis.
My concerns about vaccine safety extend far beyond the narrow question of whether vaccines cause autism. Autism and complex chronic illnesses are profoundly heterogeneous. In my experience, antecedents, mediators, and triggers vary widely among children. Vaccines contribute to oxidative or mitochondrial stress in all children. In some kids; they amplify pre‑existing vulnerabilities. For others, early-life factors—such as C‑section birth, antibiotics, or prematurity — create antecedent conditions that interact with later vaccines and precede neurodevelopmental regression.
In 2005, I gave grand rounds at the university where I had been chief resident. Simply raising the possibility that the accelerated vaccine schedule might contribute to rising autism prevalence resulted in my adjunct faculty appointment not being renewed. At the time, I used a modified schedule that reduced aluminum exposure while remaining fully compliant with Virginia’s school requirements.
In 2006, I met with AAP leadership to discuss vaccine safety concerns – which were dismissed. Despite no research funding from government or pharma, I published a dozen studies in my spare time. One 17‑year project examined whether autism risk could be reduced by applying insights learned from families. After seven years, my autism prevalence was 1 in 297—at a time when the national rate was worse than 1 in 50. I submitted the findings to the AAP in 2013, expecting interest in a six‑fold reduction in such a serious public health problem. I received no response.
My clinical observations—confirmed by independent data mining—was that children who got more vaccines were more likely to develop chronic illnesses. In my practice, under‑vaccinated children had lower rates of chronic diseases.
