RFK Jr. Blames Environmental Toxins for Rising Autism Rates, Avoids Vaccine Debate Amid Expert Backlash

Robert F. Kennedy Jr., as Health and Human Services (HHS) Secretary, recently attributed the rise in childhood autism rates in the U.S. to environmental toxins, pointing blame at pollutants in air, water, medicines, and food, while promising large-scale federally funded research to identify specific causes1 3 4.
At a recent press conference, Kennedy dismissed widely held scientific explanations that attribute increased autism diagnoses to improved awareness, screening, and broader diagnostic criteria, labeling such claims as "indefensible" and "epidemic denial"2 3 4.
Kennedy did not mention vaccines in his latest remarks, a shift from his previous public positions linking vaccines to autism, which have been broadly debunked by the scientific community3 4 5.
Kennedy promised rapid results from new HHS- and NIH-backed studies, stating a goal to "find the cause of autism by September" and to provide real-time data on autism rates, mimicking infectious disease surveillance1 3 4.

- Autism self-advocates, parents, and medical experts have strongly criticized Kennedy’s statements, arguing that:

Autism is a complex developmental disability influenced by a mix of genetic, biological, and environmental factors2 3.
Framing autism as an "epidemic" or "disease" is misleading and perpetuates stigma, fear, and misinformation, overlooking the diversity and potential of autistic individuals2 3.
The rise in autism prevalence is largely attributed to better diagnostic tools and awareness, not a true surge in incidence2 3 4.
Most children with autism do not have severe intellectual disabilities, contrary to Kennedy's claims2.
- Autism researchers and advocacy groups warn that focusing on unproven environmental or vaccine links distracts from urgent efforts to provide inclusive education, adult services, early intervention, and equitable healthcare for autistic individuals2 3.
- The CDC's latest data shows autism now affects 1 in 31 U.S. 8-year-olds, up from 1 in 36 in 2020 and 1 in 150 in 1992, with experts attributing the bulk of this increase to changes in diagnostic practices and criteria2 3 4.
- Kennedy’s approach has fueled controversy, with major autism organizations cautioning against misleading narratives and emphasizing the need for research grounded in scientific evidence and community input2 3 4.
