Discredited Autism-Vaccine Study Retracted Following Methodological Failures
A 2010 study linking hepatitis B vaccines to autism has been retracted due to fundamental flaws. Authorities continue to scrutinize related research.
Journal Pulls Controversial Vaccine Research
A 2010 research paper that previously suggested a link between hepatitis B vaccinations in newborn boys and an increased risk of autism has been officially retracted. Published in the *Journal of Toxicology and Environmental Health, Part A*, the study claimed that neonates receiving the vaccine faced triple the risk of an autism diagnosis compared to those vaccinated later or not at all.
Following the publication of the retraction, Taylor & Francis—the publisher of the journal—confirmed that an additional study by the same authors is currently under formal investigation. The publisher's Publishing Ethics & Integrity team is examining a 2008 paper titled *Hepatitis B triple series vaccine and developmental disability in U.S children aged 1-9 years*.
Flawed Methodology Exposed
The decision to retract the 2010 article followed a post-publication statistical review by an independent expert. This review identified critical methodological errors that rendered the final conclusions invalid. Specifically, the researchers relied on a sample size that was deemed too small to support the claims made. While the authors, Carolyn Gallagher, PhD, and Melody Goodman, PhD, contested the retraction, the journal maintained that the study's scientific foundations were fundamentally unsound.
David Mandell, ScD, of the University of Pennsylvania Perelman School of Medicine, highlighted that the study relied on a tiny subset of children. He noted that out of the data used, only 45 autistic children possessed a vaccination record, with only nine of those having received the hepatitis B vaccine in their first month of life. Mandell argued that the entire association presented by the authors rested on this narrow group, leading to spurious results.
Impact on Vaccination Policy
The retracted paper had previously been included in a safety review presented to the CDC's Advisory Committee on Immunization Practices on December 4. This presentation occurred just one day before the committee voted to discontinue the agency's long-standing recommendation for universal hepatitis B vaccination at birth. The inclusion of such contested material during critical policy discussions underscores the need for rigorous peer review standards.
This retraction follows a broader trend of scientific correction. In January, the *European Journal of Pediatrics* also withdrew a major clinical trial concerning leucovorin, a substance previously discussed as a potential autism treatment before official stances were reversed to focus on rare hereditary cerebral folate deficiency.

Frequently Asked Questions
Why was the 2010 study retracted?
The study was retracted because an independent statistical review found fundamental methodological flaws and concluded that the findings were unsound. The researchers utilized a sample size that was too small to provide statistically significant evidence.
What does this mean for vaccine safety?
The retraction highlights that the specific claims made in that paper were not supported by valid science. Public health agencies like the CDC continue to rely on robust, peer-reviewed data when forming vaccination recommendations.
Is other research by these authors being reviewed?
Yes, Taylor & Francis has confirmed that a 2008 paper written by the same authors is currently under investigation by their Publishing Ethics & Integrity team.
