Human Papilloma Virus Vaccination and Oropharyngeal Cancer: Knowledge, Perception and Attitude among Italian Pediatric Dentists

Background: Pediatric dentists could play a key role in the prevention of human papilloma virus (HPV)-related oropharyngeal cancer (OP-cancer). The aim of this study was to assess knowledge, perception, and attitude on HPV-related OP-cancer, HPV infection, and HPV vaccination among Italian pediatric dentists. Methods: A cross-sectional study was conducted. Pediatric dentists received, by email, a link to participate in the questionnaire online. The questionnaire comprised four parts: (i) demographic information, (ii) knowledge on HPV-related OP-cancer, HPV infection, and HPV vaccine, (iii–iiii) perceptions and attitude on HPV-related OP-cancer, HPV infection, and HPV vaccine. Data were statistically analyzed with Kruskal–Wallis and Mann–Whitney test and Pearson’s chi-square test. Results: A total of 271 pediatric dentists completed the questionnaire. Results showed a good overall knowledge; a positive perception of their role in HPV disease prevention; a good attitude in discussing sensitive topics; a need for acquiring more information about HPV’s connection to cancer, HPV infection, and HPV vaccine. Conclusions: Improving educational training programs, as well as informing about prevention of HPV-related OP-cancer, will place pediatric dentists in the front line of HPV diseases primary prevention.

Vaccinators' Perception of HPV Vaccination in the Saa Health District of Cameroon

Introduction: Cervical cancer is the second most prevalent cancer among women in Cameroon. In November 2020, the HPV vaccine was introduced into the expanded programme on immunisation. However, uptake of the vaccine has been slow in the Centre region as opposed to other regions in the country. We therefore sought to describe vaccinators' perception of HPV vaccination in Saa health district.Methods: A self-administered questionnaire with both open-ended and closed questions was used to assess the perception of HPV vaccination among 24 vaccinators from the Saa health district. Quantitative data were summarised as proportions while qualitative data were deductively and inductively coded and thematically analysed.Results: Most vaccinators (75%, n = 18) had a good knowledge about cervical cancer and HPV vaccination. Fourteen (58.3%, n = 14) vaccinators correctly reported the target group, number and spacing of doses for the HPV vaccine. Fourteen (58.3%) vaccinators favoured HPV vaccination while the others (n = 10) were sceptical. Sceptics felt manufacturers hadn't given enough proof of the safety of the vaccine and lacked confidence in government's assessment of the epidemiological situation. The COVID 19 pandemic, fear of infertility and the negative influence of social media were perceived as the main reasons for community hesitancy. Vaccinators criticised health authorities for failing to sensitise the population about the HPV vaccine before its introduction.Conclusion: Vaccinators' perceptions of HPV vaccination may influence the offer of HPV vaccination services. Measures to increase acceptance of HPV vaccination and ownership of the activity among vaccinators have to be put in place.

Predicting human papillomavirus vaccine uptake in men who have sex with men the influence of vaccine price and receiving an HPV diagnosis

Background To understand how human papillomavirus (HPV) screening results, HPV-related knowledge and attitudes are related to vaccination intention in three cost ranges and the actual vaccination behavior in a community sample of men who have sex with men (MSM). Methods MSM aged 20 years of age or older were recruited between October 2015 and May 2016 from community health centers that provide HIV testing and consultation services in Southern Taiwan and on social media. MSM were seen at baseline and again at 6 months after baseline in a cohort study. The baseline study included 253 individuals; 182 of them returned for the 6th-month follow-up. At each visit, MSM were asked to receive HPV screening and filled out a questionnaire. Structural equation modeling was used to test whether attitudinal factors and HPV screening results from the baseline affect their self-reported actual vaccine uptake at the in 6th-month follow-up. Results Our research included 171 participants from the cohort because they had full information of the study variables (mean ± SD age = 29.21 ± 6.18). Our model showed good model fit using indices such as the comparative fit index (value = 0.998) and root mean square error of approximation (value = 0.013). HPV knowledge can predict those who have intention to take up HPV vaccine no matter what the price (p = .02), and then predict vaccine uptake at the follow-up (p < .001). A positive HPV screening result can predict vaccine uptake at the follow-up (p = .004). Conclusion Our findings highlight the impact of vaccine price and HPV screening results on the intention and uptake of HPV vaccine. It is important to raise awareness of HPV in male populations. Clinicians and health educators should establish a safe and private environment for male patients for inquiring about HPV vaccine and HPV-related cancers.

Identifying the Roles of Medical Providers when Addressing Barriers to HPV Vaccination Rates in Rural NE Clinics

Background: Although many interventions to address vaccine hesitancy until now have operated on the presumption that misperceptions are due to a lack of knowledge about HPV and the vaccine, this may not always be the reason behind vaccine hesitancy. Nyhan et. al found [1] that correcting myths about vaccines- such as autism links or vaccine side effects- do not increase vaccine rates among adolescents. Medical providers play a crucial role on influencing parents’ decision to vaccinate. In a study exploring how vaccination coverage among children 19-35 months old is associated with health care providers' influence on the parents' decision to vaccinate, parents who report their providers as being influential in the study are twice as likely to respond that vaccines are safe for children [2]. In the 2016 Clinical Report on Countering Vaccine Hesitancy by the American Academy of Pediatrics, motivational interviewing is listed as a potential communication technique that may be useful as pediatricians discuss vaccines with vaccine-hesitant parents. Research Question: The research attempting to find the best approaches to reverse the increasing rates of unvaccinated minors is limited and inconclusive. This project addressed the impact of medical providers’ attitudes of HPV vaccination on their early adolescent patient populations. Methods: Our cohort prospective study first examined medical providers’ baseline attitudes and approaches of HPV vaccination in privately insured clinics in rural areas of Nebraska. A survey was sent to eleven Phase III patient centered medical home (PCMH) NE clinics. The survey assessed medical staffs’ attitudes and approaches to HPV vaccination, particularly among specific patient age groups. In addition to each clinic’s collective survey responses, baseline HPV vaccination data was collected at eleven Phase 3 PCMH rural clinics in Nebraska for pediatric patients 11-15-years-old. The follow-up intervention implemented educational interventions in the clinics to increase HPV vaccination rates for pediatric patients 9-15-years-old. Our educational outreach program at the selected 10-13 clinics will serve as these rural clinics’ first efforts to selectively work toward improving HPV vaccination rates. Results: America’s Health Rankings (2017) found 42.4% of adolescents living in rural areas compared to 52.4% in urban areas are up-to-date on their HPV immunizations. The eleven rural clinics selected for the study show only a 0.9% completion of the vaccine series for 9-11-year-old patients (n=855), and 25.0% completion of the series for 12-15-year-old patients (n=1268) as of 2019. This implies a pressing health disparity that needs addressing in rural Nebraskan communities. 92.6% of all respondents chose the 12-15 age range as the patient population the clinics would typically ask about the vaccine versus 59.6% who chose the 9-11 age range. The most chosen reason for not mentioning the HPV vaccine is “parents previously voiced vaccine hesitancy” (33.3%) followed by “not enough clinic time” (22.2%). The most popular reason contributing to parental hesitancy is “they have concerns the vaccine is not safe for their child” (70.4%). The greatest benefit of the HPV vaccine was listed as “prevention from multiple forms of cancer” (33.3%) and the greatest drawbacks were both “multiple dose series completion” (40.7%) and “difficulty in convincing parents to vaccinate minors” (40.7%). The 9-11 age range was chosen as the most difficult age group to vaccinate (33.3%). The most difficult scenarios when addressing HPV vaccination concerns were “lack of vaccine education” (55.6%), “religious reasons against the vaccine (44.4%), and “language/cultural barriers” (37%). Qualitative results were also analyzed separately and focused on each individual clinic’s strengths and weaknesses regarding vaccination encouragement. Discussion: The baseline patient data show that clinics selected for the study exhibit a large disparity of HPV vaccination rates among a vulnerable age group. Survey responses show both a clinical observation regarding parents’ low-level education levels about the HPV vaccine as well as a lack of comfort engaging in open dialogue between patients and healthcare personnel. Focusing on these two variables alone could help increase rates of vaccination significantly. Survey results ultimately illustrate the urgent need for empirically-supported educational resources that will enhance communication- both within individual clinics among staff as well as between medical staff and patients’ families- to sustainably increase HPV vaccination rates across rural clinics.
