Journal Retracts Study Showing Masks Don’t Work Claiming Science “Clearly Shows” Masks Work, But Fails to Cite Any Evidence

The peer-reviewed study “Facemasks in the COVID-19 era: A health hypothesis” by Dr Baruch Vainshelboim has been retracted by the journal Medical Hypotheses on the instruction of the Editor-in-Chief.

The study argues that neither medical nor non-medical facemasks are effective in blocking transmission of viral and infectious disease such as SARS-CoV-2, and that in the long run they are likely to damage individual health.

The retraction notice reads:

This article has been retracted at the request of the Editor-in-Chief.

Medical Hypotheses serves as a forum for innovative and often disruptive ideas in medicine and related biomedical sciences. However, our strict editorial policy is that we do not publish misleading or inaccurate citations to advance any hypotheses.

The Editorial Committee concluded that the author’s hypothesis is misleading on the following basis:

1. A broader review of existing scientific evidence clearly shows that approved masks with correct certification, and worn in compliance with guidelines, are an effective prevention of COVID-19 transmission.

2. The manuscript misquotes and selectively cites published papers. References #16, 17, 25 and 26 are all misquoted.

3. Table 1. Physiological and Psychological Effects of Wearing Facemask and Their Potential Health Consequences, generated by the author. All data in the table is unverified, and there are several speculative statements.

4. The author submitted that he is currently affiliated to Stanford University, and VA Palo Alto Health Care System. However, both institutions have confirmed that Dr Vainshelboim ended his connection with them in 2016.

A subsequent internal investigation by the Editor-in-Chief and the Publisher have determined that this article was externally peer reviewed but not with our customary standards of rigour prior to publication. The journal has re-designed its editorial and review workflow to ensure that this will not happen again in future.

If there are errors in the paper, the question is why these were not picked up and addressed with the author prior to publication in the usual manner. If some were missed and subsequently came to light, the journal could have asked for revisions to the paper to address the criticisms. That it chose to retract it completely suggests the move is political (though the allegations of dishonesty in affiliations may have played a part). There is no indication in the notice of any correspondence with the author in the matter.

The strangest criticism is the first: “A broader review of existing scientific evidence clearly shows that approved masks with correct certification, and worn in compliance with guidelines, are an effective prevention of COVID-19 transmission.” This is just a restatement, without references, of mask orthodoxy. Given that Dr Vainshelboim had provided a wide range of references in his review of the evidence, a rebuttal should surely have come in the form of a similar rigorous academic exercise, marshalling further evidence, not a bald 28-word sentence about what the evidence “clearly shows”. This is not the way robust academic research happens or science advances. The editors could have published a response, or another study drawing on further evidence that comes to a different conclusion. That they instead retract the article on account of criticisms from unnamed correspondents, drawing on unspecified evidence, is a disgraceful way to treat peer-reviewed scientific research and the scientists who produce it.

What exactly is this uncited evidence that “clearly shows” masks reduce transmission? Certainly not the only randomised controlled trial, Danmask-19, which found no significant protection for the wearers of surgical masks. And certainly not the real-world evidence comparing countries or states with mask mandates to those without.
