Abstract 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.

ObjectivesIn 2015, a publicly funded human papillomavirus (HPV) vaccination programme was implemented for gay, bisexual and other men who have sex with men (gbMSM) up to age 26 years in British Columbia, Canada. We assessed trends and correlates of HPV vaccine uptake from 2012 to 2019 in a cohort of gbMSM in Vancouver.MethodsWe recruited sexually active gbMSM aged ≥16 years using respondent-driven sampling from February 2012 to February 2015 and followed them until July 2019. We evaluated self-reported HPV vaccine trends using mixed-effects logistic regression and identified factors associated with uptake using multivariable mixed-effects Poisson regression.ResultsA total of 719 participants were recruited and completed the baseline visit, of whom 549 were unvaccinated with at least one follow-up visit. The median age was 33 years and 23% were living with HIV. HPV vaccination increased from 4% in 2012 to 28% in 2019 (p<0.001) among gbMSM >26 years, and from 9% in 2012 to 20% in 2017 (p<0.001) among gbMSM ≤26 years. Vaccination uptake increased after September 2015, following vaccination policy expansion (adjusted rate ratio (aRR)=1.82, 95% CI 1.06 to 3.12). In multivariable models, increased vaccination was associated with age ≤26 years vs ≥45 years (aRR=3.90; 95% CI 1.75 to 8.70), age 27–44 vs ≥45 years (aRR=2.86; 95% CI 1.46 to 5.62), involvement in gay community sports teams (aRR=2.31; 95% CI 1.15 to 4.64) and other groups (aRR=1.71; 95% CI 1.04 to 2.79), awareness of HIV-postexposure prophylaxis (aRR=5.50; 95% CI 1.31 to 23.09), recent sexually transmitted infection testing (aRR=2.72; 95% CI 1.60 to 4.60) and recent sex-work (aRR=2.59; 95% CI 1.08 to 6.19).ConclusionsAlthough we observed increases in HPV vaccination uptake from 2012, by 2019 HPV vaccination still remained below 30% among gbMSM in Vancouver, BC. Additional interventions are needed to increase vaccine uptake.

Objectives To investigate whether negative media coverage of the human papillomavirus (HPV) vaccine led to a decrease in the uptake of the first dose of the HPV vaccine (HPV1) in Denmark and, importantly, whether some groups of individuals were more susceptible to negative media coverage. Methods We measured HPV vaccine uptake of 12-year-old girls born in 2001 to 2004 using Danish administrative data. A quasi-experimental design was employed to assess whether a documentary that was critical of the HPV vaccine and aired in March 2015 affected HPV uptake. Results The documentary led to a quick and substantial decrease in the monthly propensity to vaccinate, which dropped 3 percentage points—or about 50%—in response to the documentary. Responses differed substantially across subgroups, and girls from families with high socioeconomic status (SES) were more susceptible to the negative media coverage. Conclusions Susceptibility to negative media coverage varied substantially across subgroups, highlighting the need for policy makers to appropriately target and differentiate initiatives to improve vaccine compliance rates.

AbstractIn 2017, 46,157 and 3,127 new oropharyngeal cancer (OPC) cases were reported in the U.S. and Texas, respectively. About 70% of OPC were attributed to human papillomavirus (HPV). However, only 51% of U.S. and 43.5% of Texas adolescents have completed the HPV vaccine series. Therefore, modeling the demographic dynamics and transmission of HPV and OPC progression is needed for accurate estimation of the economic and epidemiological impacts of HPV vaccine in a geographic area. An age-structured population dynamic model was developed for the U.S. state of Texas. With Texas-specific model parameters calibrated, this model described the dynamics of HPV-associated OPC in Texas. Parameters for the Year 2010 were used as the initial values, and the prediction for Year 2012 was compared with the real age-specific incidence rates in 23 age groups for model validation. The validated model was applied to predict 100-year age-adjusted incidence rates. The public health benefits of HPV vaccine uptake were evaluated by computer simulation. Compared with current vaccination program, increasing vaccine uptake rates by 50% would decrease the cumulative cases by 4403, within 100 years. The incremental cost-effectiveness ratio of this strategy was $94,518 per quality-adjusted life year (QALY) gained. Increasing the vaccine uptake rate by 50% can: (i) reduce the incidence rates of OPC among both males and females; (ii) improve the quality-adjusted life years for both males and females; (iii) be cost-effective and has the potential to provide tremendous public health benefits in Texas.

Aim: The aim of this study was to examine predictors of human papillomavirus (HPV) vaccine uptake or intent among parents of pre-adolescents and adolescents.Methods: A cross-sectional descriptive study was conducted among parents of girls aged 9 to 18 years, visiting two primary care clinics in central Texas from September to November 2015. Pearson’s product-moment correlation procedures and path analyses based on Health Belief Model were performed.Results: Path analysis showed that provider recommendation for HPV vaccination (β = 0.37; p < .001) and perceived HPV vaccine harm (β = -0.48; p < .001) had statistically significant direct effects on HPV vaccine uptake or intent. The perceived HPV vaccine effectiveness was directly influenced by HPV knowledge (β = 0.39; p < .001), empowerment in parent-provider relationships (β = 0.30; p = .006) and parental college education (β = 0.23; p = .039).}Conclusions: Together with parental empowerment fostering an equal partnership with providers, targeted education to improve parental HPV knowledge may convince them of the HPV vaccine effectiveness. This, in turn, may help them put the perceived HPV vaccine harm in proper perspective and allow them to make informed decisions regarding the timely HPV vaccination of their children. Because provider recommendation is one of the most important contributing factors for HPV vaccine uptake or intent, parental education and recommendations from nurses will help reduce the knowledge gaps and empower parents to make the timely decisions to vaccinate their children.

Background: Despite the insupportable burden caused by the human papillomavirus (HPV) and high vaccine acceptability, vaccination programs are not currently available for men who have sex with men (MSM). We aimed to assess HPV infection by examining the willingness for vaccination among MSM and cost-effectiveness of the Chinese 2-valent HPV vaccine.Methods: We recruited MSM in Shenyang, China between July and December 2020 to conduct anal HPV testing and an online survey regarding HPV-related knowledge and vaccine acceptability. We performed a cost-effectiveness analysis to evaluate the incremental cost-effectiveness ratios (ICERs) of the Chinese 2-valent HPV vaccine.Results: A total of 234 participants completed the online survey; of those, 203 were successfully tested for HPV. The median age was 30 years [interquartile range (IQR): 23–38 years]. Most participants had at least undergraduate education (136/234, 58.1%). The acceptability rate for the free HPV vaccine was 57.7% (135/234). The prevalence of HPV types 16 and 18 was 14.9% (18/121) and 26.8% (22/82) in the willing and unwilling to vaccinate groups, respectively (P &gt; 0.05). The prevalence of high-risk HPV among participants aged &lt;30 and ≥50 years was 48.6 and 38.9%, respectively. Using the Chinese per capita gross domestic product (GDP) as a threshold, the Chinese 2-valent HPV vaccine would be a “very cost-effective” strategy, with an ICER value of USD 4,411. This evidence showed that the Chinese 2-valent HPV vaccine was more cost-effective than other imported vaccines.Conclusions: Targeted strategies should be utilized in MSM with different rates of vaccine acceptability. A pilot HPV vaccination program based on the Chinese 2-valent HPV vaccine for MSM is urgently warranted to reduce the burden of HPV and anal cancer.

Cervical cancer is the second leading cause of cancer and one of the leading causes of cancer-related death in women in India. Human papillomavirus (HPV) vaccine uptake in India is low due to cost, low awareness of HPV, social stigma, and other factors. We assessed the awareness, attitudes, and beliefs regarding HPV and HPV vaccination and explored the barriers and challenges to HPV vaccine intent among women in Mangalore, India. An exploratory study was conducted using two focus group discussions (FGDs) and six in-depth one-on-one interviews. FGD-1 comprised nine women aged 18 to 26 years, and FGD-2 comprised seven women aged 27 to 45 years. The FGDs were recorded, transcribed, and analyzed using thematic content analysis. Themes identified were limited knowledge of HPV and vaccine, stigma associated with receiving HPV vaccine, vaccine safety concerns, and cost as a barrier to receiving vaccine. Participants expressed desire for physician and government recommendation of the HPV vaccine to validate vaccine intent. Contrasting themes between the two FGDs include support for vaccination at a younger age and lower perception of stigma and judgment in the 18- to 26-year-old group; however, participants in the 27- to 45-year-old group support vaccination at an older age and endorse greater fear of stigma and judgment associated with obtaining vaccination. Education regarding HPV-associated diseases and the HPV vaccine for the general public, physicians, and government officials in conjunction with lowering vaccine cost, improving vaccine access, and encouraging strong physician recommendations are key strategies to scale up HPV vaccine implementation in India.

Abstract Context.—Reflex human papillomavirus (HPV) testing has been designated in consensus guidelines as “preferred” for women with atypical squamous cells of undetermined significance (ASC-US) liquid-based cytology (LBC) results, and colposcopy is currently recommended for patients with HPV-positive ASC-US results. Data from large clinical practices using newer screening methods and current cytology terminology are limited. Objectives.—We analyzed data from patients with ASC-US LBC and positive HPV test results. We also assessed the impact of the presence or absence of an endocervical cell/ transformation zone sample (EC/TZS) on biopsy diagnoses. Design.—The information system of a large women's hospital serving an older-than-average population was searched over a 21-month period between July 1, 2005, and March 31, 2007, for HPV-positive cases interpreted as ASC-US (Bethesda System 2001) using computer-imaged LBC. Histologic diagnoses, patient ages, and presence or absence of an EC/TZS were analyzed. The average follow-up period was 7.5 months. Results.—Among 4273 women with HPV-positive ASC-US results, the cumulative cervical intraepithelial neoplasia 2 or 3 (CIN 2/3) and CIN 1 rates for 2192 women with available biopsies were 5.1% and 43.6%, respectively. Cervical intraepithelial neoplasia 2/3 and CIN 1 rates for women with HPV-positive ASC-US results were not significantly different for women with and without an EC/TZS. Conclusions.—The risk of CIN 2/3 in the study population was significantly lower than reported in widely cited trial data. Neither presence nor absence of an EC/TZS, nor the age of the patient, had a statistically significant impact on the likelihood of biopsy diagnoses of CIN 2/3 and CIN 1 for patients with HPV-positive ASC-US test results.
