FactCheck.org: Kennedy Cites Flawed Paper in Bid to Justify Vaccine-Autism Link

As Robert F. Kennedy Jr. faces Senate confirmation votes for his nomination as Secretary of Health and Human Services, we have rounded up a series of essential reads by our project FactCheck.org on Kennedy’s record and remarks about relevant and consequential topics from vaccination and autism to Covid-19 and bird flu.

In his second day of confirmation hearings, on Jan. 30 before the Senate Committee on Health, Education, Labor and Pensions, Kennedy refused to say that vaccines do not cause autism, despite a large body of evidence showing that there is no link. Kennedy pointed to a flawed paper to suggest there is credible evidence to claim that vaccines cause autism.

When questioned about studies showing there is no link, Kennedy claimed that “there are other studies out there” suggesting a link between vaccines and autism. However, the findings on this topic are not mixed, according to FactCheck.org. The single paper Kennedy cited in the hearing – which claims to have found that vaccinated “children were significantly more likely than the unvaccinated to have been diagnosed” with autism and other neurodevelopmental disorders – was not rigorous, experts told FactCheck.org. Jeffrey S. Morris, director of the division of biostatistics at the University of Pennsylvania’s Perelman School of Medicine, told FactCheck.org that the paper “has so many severe methodological issues, it clearly should not have passed any legitimate peer review.”

Since Kennedy announced a presidential bid in 2023, FactCheck.org’s SciCheck team has examined his record on a number of occasions, including in this three-part series in late 2023.
