PLOS One Retracts Covid-19 Vaccination Survey After Peer Review Concerns
The PLOS One Editors have retracted a 2023 survey that examined beliefs, perceptions, and clinical manifestations before and after Covid-19 vaccination among physiotherapy students in the United Arab Emirates. The stated reason is not a dispute over the topic itself, but a failure in the vetting process behind the paper. The journal said the article’s peer review process was compromised, and it also raised concerns about compliance with PLOS policy on manipulation of the publication process.
Retractions for process failures carry a different weight than retractions for flawed data. Here, the journal did not present a scientific critique of the survey’s conclusions in the notice itself. Instead, the action centers on the integrity of the editorial pathway that brought the article into print.
Integrity Concerns Centered on the Publication Process
The original paper, authored by Almheiri, Hazari, Kumar, Kumar, and Girish, appeared in PLOS One in 2023. Its title signaled an observational survey focused on perceptions of Covid-19 vaccination and self-reported clinical manifestations among physiotherapy students in the UAE. The retraction notice did not reproduce the study results, and it did not offer a point-by-point scientific rebuttal of the manuscript’s findings.
Instead, the journal took the unusual but necessary step of removing the article from the active literature because the review pathway could not be trusted. In academic publishing, peer review is the gatekeeper that filters out weak design, unsupported inference, and work that does not meet editorial standards. Once that gatekeeping function is compromised, the problem extends beyond a single manuscript. It reaches the reliability of the record itself.
The notice also cites concerns about compliance with PLOS policy on Manipulation of the Publication Process. That language places the case in the broader category of publication ethics, where issues such as compromised reviewer selection, irregular review patterns, or other forms of process abuse can invalidate confidence in the final article, even before the underlying data are reconsidered.
What the Retraction Does and Does Not Say
The editors’ statement is concise, and the brevity matters. No error correction was issued. No corrected version was offered. No expression of concern was listed in place of the paper. The action was a full retraction.
Two of the listed authors, AH and SK, did not agree with the retraction. SA, PK, and SG either did not respond directly or could not be reached. Those positions are part of the record, and they show that the retraction was not universally accepted by the author group. Even so, the journal moved ahead with removal of the article from the valid corpus of literature.
A retraction like this does not necessarily prove that every dataset point in the paper was false. It does mean the journal no longer stands behind the article as a vetted scientific contribution. For clinicians, educators, and researchers, that distinction is decisive. A paper that has lost editorial legitimacy should not be relied on as evidence in teaching, citation, or downstream synthesis.
Why Process Failures Matter in Vaccine-Related Survey Research
Survey studies about vaccination attitudes and symptom experiences are especially vulnerable to methodological overinterpretation. They often depend on self-report, subject to recall bias, selection bias, and the limitations of cross-sectional design. When such a paper also enters the literature through a compromised review channel, confidence drops even further.
Physiotherapy students are a defined population with professional exposure to health information and clinical environments, which can make their opinions on vaccination particularly relevant. Even so, relevance does not substitute for rigor. A study can ask a timely question and still fail the standards required for publication if the review process is manipulated or inadequately controlled.
The result is broader than one withdrawn citation. Meta-analyses, teaching materials, policy summaries, and literature reviews can all absorb and repeat findings from papers that should never have cleared editorial screening. Retractions interrupt that chain, but only if readers notice them and databases update their records promptly.
The Retraction Notice Becomes the Key Record
In this case, the retraction notice itself is now the most reliable document attached to the article. The original paper remains identifiable by citation, title, and DOI, but its status has changed. The published notice gives the journal’s final position: the peer review process was compromised, and there were concerns about manipulation of the publication process.
That is a narrow statement, but it is a strong one. It signals that the integrity issue was procedural and serious enough to warrant withdrawal from the literature. It also explains why the editorial office acted even without a public scientific erratum detailing problems in the data or analysis.
For the broader research community, this case is another reminder that editorial due diligence is not a formality. A manuscript can be well packaged, timely, and thematically relevant, yet still fail the standard that matters most: trustworthy review before publication. Once that standard is breached, retraction becomes the appropriate corrective action, even when the underlying scientific topic remains important.
The notice closes the matter without offering a substitute analysis or a corrected evidentiary base. What remains is a withdrawn survey, an unresolved disagreement from part of the author group, and a public record that now warns readers not to treat the 2023 article as dependable evidence.
