Study Findings and Early Use
The paper, published in May 2024 in *BMJ Public Health*, examined excess-mortality data from 47 Western nations for the period 2020-2022. Although the article did not claim a direct causal link to vaccination, the wording was seized on by vaccine-skeptical outlets and several U.S. Republican lawmakers as evidence that COVID-19 vaccines had caused widespread deaths.
Investigation and Retraction
On August 12, 2026 the BMJ Publishing Group withdrew the study, stating that the discussion of mortality causes was “unbalanced,” lacked rigor, and contained misinformation. An ethics investigation by the Princess Máxima Center for Pediatric Oncology in Utrecht found breaches of two-thirds of the scientific-integrity standards examined, noting that the authors gave disproportionate attention to vaccines and containment measures while overlooking alternative explanations. The BMJ’s retraction notice echoed these concerns, describing the article’s methodology as flawed and its original work limited.
Author and Institutional Reactions
Corresponding author Saskia Mostert testified before a U.S. congressional subcommittee in June 2026, describing the backlash as “blind and irrational fury” and announcing her resignation from the Princess Máxima Center after the integrity probe began. Mostert offered revisions to address the journal’s criticisms, but the BMJ deemed the proposed edits insufficient. The Center’s report also characterized the excess-mortality figure as already known and not newsworthy, and it accused the authors of cherry-picking supportive data.
Impact on Vaccine Discourse
The study’s ambiguous conclusion was repeatedly cited in anti-vaccine articles and social-media posts as proof that COVID-19 vaccines increased mortality—a claim the paper never explicitly made. Researchers and public-health officials have highlighted the retraction as a corrective step that removes a source of misinformation that had been used to fuel unfounded criticism of vaccines, which have been documented to save millions of lives since 2020.
What’s Next
The BMJ’s retraction, supported by the Princess Máxima Center and two of the four authors, represents the journal’s most severe corrective action. The Center’s ethics committee recommends greater transparency and the release of detailed pandemic-policy data to enable independent evaluation of the relationship between containment measures, vaccination campaigns, and excess mortality.
