One more reason why our nation is a laughing stock worldwide.
In his second day of confirmation hearings, Robert F. Kennedy Jr., President Donald Trump’s pick to lead the Department of Health and Human Services, refused to say that vaccines do not cause autism -- despite a large body of evidence showing there is no link. He also pointed to a flawed paper...

Flawed Paper
Near the end of the more than three-hour hearing, Cassidy confronted Kennedy with a
2014 meta analysis, reminding him of his promise that he would say vaccines do not cause autism if shown the data.
“The title tells it all,” Cassidy said of the study, which was published in the journal Vaccine by researchers in Australia. “Vaccines are not associated with autism: An evidence-based meta-analysis of case-control and cohort studies.”
“You show me those scientific studies, and you and I can meet about it,” Kennedy
said. “There are other studies as well, and I’d love to show those to you. There’s a study that came out last week of 47,000 9-year-olds in the Medicaid system in Florida — I think a Louisiana scientist called Mawson — that shows the opposite. There are other studies out there. I just want to follow the science.”
Contrary to Kennedy’s claim that “there are other studies out there,” the literature on vaccines and autism is not mixed, unlike many other scientific topics. As
David Mandell, a psychiatric epidemiologist at the University of Pennsylvania,
previously told us, “Every single rigorous study we have” shows “no association” between autism and vaccination.
The
specific paper Kennedy cited — which claims to have found that “[v]accinated children were significantly more likely than the unvaccinated to have been diagnosed” with autism and a variety of other neurodevelopmental disorders — is not rigorous.
“I have read this paper carefully, and it has so many severe methodological issues, it clearly should not have passed any legitimate peer review,”
Jeffrey S. Morris, director of the division of biostatistics at the University of Pennsylvania’s Perelman School of Medicine, told us.
The paper was published on Jan. 23 in
Science, Public Health Policy and the Law, an outlet that claims to be a peer-reviewed journal, but as we have noted
before, is not available on PubMed Central, the National Institutes of Health’s database of biomedical research, nor
indexed on MEDLINE, which requires
some evaluation of journal quality. The
editor-in-chief and other board members, including the
section editor for the paper, are well-known spreaders of vaccine misinformation.
The two authors, including lead author Anthony Mawson, are affiliated with Chalfont Research Institute in Mississippi, which does not have a website and appears to use a residential home as a mailing address, based on IRS
records. Both authors have previously published work on vaccines that has been
retracted. The paper was funded by the National Vaccine Information Center, an anti-vaccine group.
