- Anonymity debases debate, and invites invective; in particular, in controversial fields where the financial stakes are highest, anonymity provide the shield for the accuser who is free to use lethal weapons to suppress inconvenient evidence that poses a threat.
The article, A Lowered Probability Of Pregnancy In Females In The USA Aged 25–29 Who Received A Human Papillomavirus Vaccine Injection, by Gayle DeLong, PhD, was published in June 2018 after three scientists peer-reviewed the article. [ Research Gate]
The article is a detailed statistical analysis of government data compiled by the National Health and Nutrition Examination Survey (NHANES) – which NIH describes as “unique in that it combines interviews and physical examinations.” The data revealed that 60% of women who had not received the HPV vaccine had been pregnant at least once, while only 35% of recipients of the HPV vaccine had ever conceived. Dr. DeLong offered possible biological mechanisms for the results. When it first appeared, the editors promoted it by offering it free. By early December 2019, the number of views reached close to 24,000.
A principle of medical ethics is that if there is a signal that a medical intervention – be it a drug, a device, or a vaccine – even if the evidence is not conclusive, the issue must be investigated to ensure the safety of the treatment. In contradiction to medical ethics, the public interest, and scientific progress, an all- powerful vaccine lobby has declared: “the science is settled… vaccines are safe and effective.” They have proceeded to suppress publication of research papers that raise safety questions. Anyone – physician, parent, or scientist – who expresses skepticism about the blanket “safe and effective” vaccine mantra, is deemed a heretic.
The high interest that Dr. DeLong’s paper generated appears to have raised alarms within the ranks of the HPV vaccine stakeholders. Merck, whose HPV vaccine is used exclusively in the U.S., and its battalion of sock-puppets whose endless trolling and spamming of papers that raise vaccine safety concerns fuels the trumped up vaccine science war.
“My paper did not claim to offer a final answer to this issue. It simply raised concerns and called for further investigation into a question that may have an enormous impact on the reproductive health of millions of women.”
The first of the hit squad assaults was levied by David Gorski, MD who issues his poison arrows under the pseudonyms — “Orac” or “Respectful Insolence.” He trashed Dr. DeLong personally with vicious broad brushstrokes; including her and her children’s medical issues; her competence, her article, the journal, and several of the authors whom she cited. His invectives were followed by a side-kick, who goes by the pseudonym “Skeptical Raptor”.
On October 23, 2019, Dr. DeLong received an email stating that the publisher (Taylor & Francis) and the Editor-in-Chief Dr. Sam Kacew had opened an investigation of the paper, based on “several public and private expressions of concern about flaws in analysis.” She was given two weeks to respond to critical comments from four ANONYMOUS post-publication reviewers, which she did.
- The gist of the anonymous “major criticism” – as identified by Editor-in-Chief – and Dr. DeLong’s responses are as follows:
- Methodological Issues: Potential confounders are not accounted for or simply ignored such as an economic downturn, societal trends including postponing pregnancy, increased women in the workforce, changes in contraceptive use, contraceptive failure rates, etc. All these factors impact pregnancy but were not addressed.
The trends mentioned in this criticism address the decline in the overall birth rate. The value of my study is that each observation identifies whether a woman received the HPV vaccine and whether that woman had ever been pregnant. To confirm that overall trends were not influencing the results, I added time trends to the statistical analysis and the results remained: Women who received the HPV vaccine were less likely to have ever been pregnant.
- Misinterpretation of data: Extrapolation of results that the number of pregnancies due to the vaccine are unfounded and supported by findings from studies by an author that uses VAERS database that relies on self-reported adverse events without verification makes the results dubious.
The data I use come from the National Health and Nutrition Examination Survey (NHANES), which is a non-random survey of people living in the United States. By design, each observation represents many more people than the individual who is surveyed. The very essence of NHANES is to generalize from the observations, and the database includes specific weights for each observation.
The comment about the Vaccine Adverse Events Reporting System (VAERS) is not relevant. While I cite an author who uses VAERS, the citation serves merely as background and plays no major role in the analysis.
- Validity questionable: The issues of selection bias, lack of similar observations in USA and Europe, weak biological plausibility and inaccurate statement regarding dose response are all factors that raise doubts regarding the data.
The data used in the analysis come from the U.S. government. If the responses to questions asked in the course of a national survey sponsored by the U.S. government are not valid, why ask the questions?
These criticisms are flat out wrong. No selection bias exists: I use every observation where the person surveyed includes answers to all the questions I use in the analysis. There are similar observations in Europe: In a separate study, I show that birth rates are falling in European countries that have implemented wide-spread HPV vaccine programs. That study is here. Not only does biological plausibility exist, studies continue to be published that point to a link between the autoimmunity that vaccines can induce and fertility issues. The statement regarding dose response in the paper is correct: I confirmed my interpretation with two independent statisticians.
- Statistical analysis: The use of the SAS package in this case is not appropriate as this package cannot judge the validity of the questions asked, the selection of variables are biased especially as this statistical model excluded variables in the NHANES data such as contraceptive use. The authors do not provide criteria for including or excluding variables which is crucial.
The data used in the analysis comes from the U.S. government. The variables I include – age, income, education, and race/ethnicity – are standard demographic and socioeconomic factors that could affect the probability of ever being pregnant.
Concerning contraception, the NHANES database contains fragmentary data. The survey includes questions on only three types of contraception, and many women provided no response to the questions. Certainly, a follow-up study to determine whether contraceptive use influences the results is warranted, but it is beyond the scope of this database and this paper. Certainly, further study is warranted.

On December 10, 2019, the publisher informed Dr. DeLong in an email that the “concerns raised by the reviewers still stand,” and the article was being retracted. The retraction notice states that all post-publication reviewers – WHOSE IDENTITY IS SHIELDED — “described serious flaws in the statistical analysis and interpretation of the data in this paper.” The retraction notice provides no details about what constitutes “serious flaws”.
The issue of post-publication anonymity of reviewers whose criticism is often lacerating, is highly controversial.
Several interesting articles dealt with the issue in 2015:
- An exchange of communications between PubPeer, the champions of anonymous post-publication peer-review (PPPR) and Philip Moriarty in: Should Post-Publication Peer Review Be Anonymous? Times Higher Education (2015):
“Among the criticisms that are frequently made of peer review is that referees’ anonymity allows laziness, discourtesy and conflicts of interest to flourish. There is even greater concern about anonymity in the case of so-called post-publication peer review (PPPR), which permits anyone with an internet connection to comment on published papers”.
Moriarty cites a scathing editorial by the editor –in- chief of the journal Plant Physiology who stated: “Given that the majority of comments show the most petty kind of scientific criticism, can there be any doubt that the intent often is to pillory, to do so publicly and without accountability?”
PubPeer organizers acknowledged that:
“The main arguments against anonymity are that it allows commenters to blacken the names of their competitors with impunity and to hide conflicts of interest.”
- Another thoughtful article that examines the pros and cons of anonymous Post-Publication Peer Review by Leonid Schneider makes the following points:
“The main criticism of traditional journal peer review is its intransparency [opacity]. COI are often suspected when fishy manuscripts are waved through towards publication, while good research studies are sabotaged by competing or even personally hostile colleagues acting as peer reviewers. Of course, the job of a good journal editor is to prevent such COI, yet the very system of peer review intransparency allows many editors to rig the game without anyone noticing…even the most outrageous COIs can easily creep into anonymous PPPR, and the moderating authority either tolerates or is not always sufficiently able to prevent them…
signed PPPR is much more likely to be taken seriously by authors, journals and relevant research institutions. Eventually, scientists engaging in open, signed PPPR can even advance their careers and make an internationally recognised name for themselves. It is very tempting to leave less thought-through criticisms under the conditions of anonymity, simply because it is so easy to separate oneself from them.”
- Medicine has been derailed from its ethical foundation — “first, do no harm” — by the ubiquitous influence of Pharma which controls the science with confidentiality clauses, and by keeping the data under lock and key. When it comes to vaccines — the most contentious field of medicine — the integrity of the science is further undermined by the refusal of those in control of the science and those who control public policy, to allow access to the data for independent review. Furthermore, these gatekeepers suppress open debate about the claimed findings whose validity is not verified by independent scientists.
