Introduction: Human papillomavirus vaccination coverage has not been achieved in the general population. There are factors that interfere with the acceptance of the vaccine by the parents of adolescent girls. Objective: To correlate knowledge of human papillomavirus, knowledge of the vaccine against the virus, and beliefs about the vaccine with vaccine acceptance among parents of adolescent girls aged 9-12 years in Chihuahua, Mexico. Materials and Methods: A descriptive, correlational, and cross-sectional study was conducted with a census sample of 145 parents of girls between the ages of 9 and 12 enrolled in three public elementary schools in an urban area of Chihuahua, Mexico. Results: Knowledge of human papillomavirus was related to vaccine acceptance (p < 0.009), as was knowledge of the human papillomavirus vaccine (p < 0.030). In contrast, beliefs about HPV and the vaccine were not related (p < 0.747). Discussion: The results are consistent with previous literature in that knowledge of the virus and its vaccine is low, but the scores were lower in this study. In contrast, HPV vaccine acceptance tends to be high, as in previous studies. Conclusions: Knowledge about human papillomavirus and the vaccine was associated with parental acceptance of giving it to their daughters. [ABSTRACT FROM AUTHOR]

Human Papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide, responsible for 4.5 % of all cancers in both sexes. HPV vaccination, with similar levels of efficacy and safety in both sexes, is aimed at women to prevent cervical cancer. The transmissibility of the virus in both sexes and the herd immunity provided by universal vaccination makes its extension to the male sex a matter not only of public health but also a bioethical dilemma related to the protection of health and the equitable distribution of resources. This research addresses the bioethical analysis of the extension of HPV vaccination to both sexes. [ABSTRACT FROM AUTHOR]

Within the current discussions on immunization practices, Human Papillomavirus (HPV) made various challenges from bioethics: firstly, there are controversies regarding the efficacy and safety profile of marketed vaccines, and with respect to their cost-effectiveness. Around the discussion is evident in empirical studies that the informed consent process does not provide the necessary elements for the patients and their legal representatives can participate meaningfully in the process of making decisions about vaccination. This article presents an overview of the status of the issue, with an analysis from bioethics from the principle of proportionality and the deliberative syncretic method and suggests some input to optimize the process of informed consent for the HPV vaccine.
