A 2024 BMJ Public Health piece claimed excess mortality remained high post-peak in several regions, fueling vaccine-skeptic narratives online.

Corresponding author Saskia Mostert initially did not cooperate but later expressed willingness to make changes; editors deemed those changes insufficient due to imbalanced discussion and misinformation.

Investigators concluded the paper misrepresented literature, citing sources supporting its view while neglecting opposing interpretations and failing to discuss relevant counterpoints.

The retraction followed heightened scrutiny after an expression of concern, media coverage, and external critiques about the re-analysis timeframe (2020–2022) amid shifting excess mortality trends.

Following inquiries by the BMJ Group and the Princess Maxima Center for Pediatric Oncology, where several authors were affiliated, an expression of concern was issued in 2024 and the study has now been fully retracted, with support from the institution and two of the four authors.

The retraction represents the most severe form of disavowal in scientific publishing, formally withdrawing the study and its findings from the scientific record.

Before the retraction, the publisher issued a cautionary notice urging caution in interpreting the study’s findings.

The case sits within a broader discussion of how excess mortality estimates during the pandemic were communicated and interpreted by researchers, media, and policymakers.

Originally, the study suggested a need for more precise data to explore the roles of confinement measures and vaccination rather than proving a causal link to vaccines.

The NZ Doctor piece highlighted that the study was widely misreported, with public discourse potentially overstating its conclusions.

The study faced methodological criticisms and concerns about potentially spreading misinformation regarding the causes of excess mortality without establishing a link to Covid vaccination.

BMJ Public Health’s retraction of the 2024 analysis on excess mortality during the pandemic followed scrutiny over its methodology and interpretations.
