Source: The Daily Iowan The Nov. 29 editorial "Recommend Pap smears, not vaccines, to prevent cervical cancer" completely missed the mark with regard to HPV vaccines. We are researchers and clinicians at the University of Iowa who study and treat HPV and other infectious diseases. It is disturbing to think that the article might dissuade individuals from getting a safe and effective vaccine that can prevent cancer. First of all, it has been conclusively demonstrated that the vaccines are effective at preventing HPV infection. Cervical cancer is caused by HPV. Additionally, cancers of the head and neck are linked to HPV, including cancers in males. It has been clearly shown that the vaccines prevent the development of precursors to cervical cancer. In the editorial, Dr. Diane Harper was quoted as saying, "If doctors tell patients that this vaccination will prevent cancer, they're telling them a lie." This statement from Dr. Harper is simply misleading. In the vaccine studies, non-treatment of precursor lesions in the placebo group in the context of a clinical trial was considered unethical, and therefore, any precursor lesions were treated. Subsequent development of cancer in the placebo group was prevented by the required ethical treatment. Thus, the trials could not evaluate prevention of advanced cancer, per se. Because it takes cervical cancer a long time to develop, it will take about 15 more years to have data on incidence rates of cervical cancer from a large vaccinated general population. Because the vaccines prevent HPV infection and HPV-associated [...]
