This 2026 public comment letter and book excerpt from Aaron Siri of the Informed Consent Action Network (ICAN) challenge the federal government’s baseless assertion that infant vaccines do not cause autism. The text argues that federal health agencies lack the specific, rigorous studies necessary to support their safety claims, citing multiple Institute of Medicine (IOM) reports that found inadequate evidence to either accept or reject a causal link. Siri details his extensive legal and professional efforts to obtain such research from the CDC and NIH, claiming the agencies provided only irrelevant studies focused on the MMR vaccine or thimerosal rather than the full infant schedule. The sources further suggest a high correlation between increased vaccination rates and the rise of chronic childhood illnesses, emphasizing a need for independent research comparing vaccinated and unvaccinated children. Ultimately, the author contends that the medical establishment relies on ideological belief rather than transparent data, leading to a significant accountability gap in public health.
