      The medical profession, including medical schools and hospitals, is now a part of the health care industry, and implementation of editorial policies of medical journals is commonly biased in favor of business interests. PubMed Commons has offered the only, albeit constrained, open forum to air dissenting research and opinions in science-based language. Discontinuation of PubMed Commons will silence any questioning of the industry-sponsored promotional publications indexed in PubMed.

      Prophylactic HPV vaccines consist of the major coat protein L1 assembled into macromolecular structures – virus like particles (VLPs) that mimic the geometry and morphology of the wild type virus coat or capsid but do not contain full length HPV DNA genomes. VLPs, with their repeat crystalline array of L1 pentamers as in the wild type virus, are intrinsically immunogenic(1) eliciting high antibody titres with or without adjuvant(2). The safety profile of the licensed vaccines was assessed extensively in randomized clinical trials (RCTs)(3-5). In the 10 years since the first 2 commercial vaccines Gardasil and Cervarix were licensed, the safety profile has been intensively monitored in the post-licensure setting by robust pharmacovigilance using both passive and active surveillance (3, 6). These studies, which collectively have included millions of subjects, provide no evidence whatsoever to support the speculation that HPV vaccines by virtue of their protein content, adjuvants or any other element within the formulation –could induce, trigger or exacerbate auto-immune disorders, thromboembolic events, demyelinating diseases or other chronic conditions.<br> The Global Advisory Committee on Vaccine Safety of the World Health Organisation has reviewed the safety data for HPV vaccines on several occasions http://www.who.int/vaccine_safety/committee/topics/hpv/en/ GACVS stated in 2014: “In summary, the GACVS continues to closely monitor the safety of HPV vaccines and, based on a careful examination of the available evidence, continues to affirm that its benefit-risk profile remains favorable. The Committee is concerned, however, by the claims of harm that are being raised on the basis of anecdotal observations and reports in the absence of biological or epidemiological substantiation. While the reporting of adverse events following immunization by the public and health care providers should be encouraged and remains the cornerstone of safety surveillance, their interpretation requires due diligence and great care. As stated before, allegations of harm from vaccination based on weak evidence can lead to real harm when, as a result, safe and effective vaccines cease to be used. To date, there is no scientific evidence that aluminium-containing vaccines cause harm, that the presence of aluminium at the injection site (the MMF “tattoo”) is related to any autoimmune syndrome, and that HPV DNA fragments are responsible for inflammation, cerebral vasculitis or other immune-mediated phenomena.” http://www.who.int/vaccine_safety/committee/topics/hpv/GACVS_Statement_HPV_12_Mar_2014.pdf Efficacy against vaccine type high grade cervical intraepithelial neoplasia CIN3 (the well-established precursor of cervical cancer(7)) has been demonstrated for the vaccines in the relevant RCTs (8-10). Cervical cancer cannot be used for ethical reasons as an end point in clinical trials (7). With regard to screening, contrary to the misleading comments by Dr. Lee, there is a large and authoritative body of evidence (including many RCTs) showing that any of the approved HPV tests is substantially more sensitive for detection of CIN2, CIN3, or cancer than cytology (11). The figure he quotes of 58% sensitivity is the result of a controversial application of “verification bias adjustment” in detection of CIN2 or worse, in a single trial. Large systematic reviews have consistently reported much higher sensitivity of HPV testing compared to cytology (12). The sensitivity of HPV testing is not at issue; rather specificity is a concern. As we emphasized in the article, HPV testing does require a secondary triage method to identify persistent infection and cancer precursors that require treatment, because HPV is very common and most infections “clear”. There are several choice of triage strategy prior to treatment; HPV typing and cytology or its analogues are most often proposed. Automated methods will soon be available. Carcinogenic human papillomavirus infections are a global public health problem, >80 % of the annual ≥530,000 cervical cancer cases occur in resource poor countries in which the disease is often incurable (13). Whatever preventive measures are adopted, evaluating the impact of interventions to control infection and disease requires a global perspective; from this perspective the promise of HPV vaccination and HPV testing are overwhelmingly supported by highly credible data. • Mark Schiffman • , John Doorbar • , Nicolas Wentzensen • , Silvia de Sanjosé • , Carole Fakhry • , Bradley J.
