Three scientific papers that raised questions about vaccine safety and were used by the Trump administration to justify controversial changes to US vaccine policies have over the last two months been removed, retracted or placed under investigation by the journals that published them.
In some cases, the actions occurred years after scientists first raised alarms about the studies’ scientific merits.
Robert F Kennedy Jr, the US health secretary who has been a leader in the anti-vaccine movement for decades, relied on two of the studies that are now facing scrutiny for a 2023 book he co-wrote that argued unvaccinated children were healthier than children who had been vaccinated. The US Centers for Disease Control and Prevention (CDC) cited one of the papers when it changed its long-held position that vaccines do not cause autism, cutting against the scientific consensus. And all three papers were cited by a lawyer, Aaron Siri, who called for changes to the childhood immunization schedule before an influential federal vaccine advisory panel. Siri is the managing partner of Siri & Glimstad and has served as a lawyer for a prominent anti-vaccine group.

[A paper] by Carolyn M Gallagher and Melody S Goodman, was published in 2010 in the Journal of Toxicology and Environmental Health, Part A, and found boys vaccinated for hepatitis B in their first four weeks of life were more likely to be diagnosed with autism.

The CDC cited the hepatitis B paper in November when it changed its stance on a possible link between vaccines and autism at Kennedy’s direction. The reworked page now states at the top that “Studies supporting a link have been ignored by health authorities” and later cites the paper.
HHS did not respond to the Guardian’s questions about whether the CDC would update its page.
Morgan McSweeney, a scientist who posts on social media as Dr.Noc, was moved to make a six-minute video debunking the paper after seeing the CDC’s changes. The authors, relying on a small number of cases, said their findings suggested male newborns vaccinated with the hepatitis B vaccine had a higher risk of autism diagnosis.
“This was a low-quality, very small study that was not replicated. So yeah, the CDC page now says that some studies supporting a link have been ignored by health authorities,” McSweeney said in the video, which now has more than 5m views between Instagram and TikTok. “And maybe that’s a little bit true, because the studies they’re showing here are worth less than a fart in the summer breeze.”
