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.

Abstract Background Human Papillomavirus (HPV) is the most common sexually transmitted infection in Canada and around the world. Vaccination is an effective prevention strategy, but uptake is low, especially among newcomers to Canada. We sought to understand newcomers’ knowledge, attitudes, and beliefs (KAB) on HPV and HPV vaccination and their role in HPV vaccine acceptance. Methods Newcomers were defined as individuals born outside Canada, (i.e., individuals born in a different country, the majority of whom are immigrants or refugees, but also includes students and undocumented migrants). Eligible participants were newcomers, aged 16 or older and who could read or write in English, French or Arabic. Surveys were administered in two community health centres in Ottawa, Canada that primarily engage with newcomer populations. Follow-up interviews were conducted either at the community health centre or over the phone, depending on participants’ preferences. Results Fifty participants completed the survey, the majority of whom were women (74%) and spoke Arabic as their first language (54%). Seven participants completed supplemental interviews to complement their survey responses. The majority (70%) of participants had not previously heard of HPV. Less than half (46%) knew that the vaccine is effective in preventing certain types of cancer; nearly 40% incorrectly believed the vaccine could cure HPV. Qualitative interviews supported the survey findings. Conclusions Despite a lack of HPV knowledge due to cultural and language barriers, there is still a strong desire among newcomers to receive the vaccine, especially when accompanied by a physician recommendation. Cultural and language-appropriate resources are needed to help newcomers make informed vaccination decisions and promote HPV vaccine uptake.

Background In France, human papillomavirus (HPV) vaccination has been recommended in 2016 for men who have sex with men (MSM) up to age 26 years. Aim We aimed to estimate HPV vaccine coverage in 18–28 year-old MSM and identify uptake determinants. Methods We collected data on socio-demographic characteristics, sexual behaviour, sexually transmitted diseases (STI) screening and vaccination uptake using a voluntary cross-sectional online survey conducted in 2019 targeting MSM. We calculated coverage of at least one dose of HPV vaccine and prevalence ratios (PR) of determinants with 95% confidence intervals (CI) using Poisson regression. Results Of 9,469 respondents (age range: 18–28 years), 15% (95% CI: 14–16) reported being vaccinated for HPV. Coverage was significantly higher among MSM < 24 years (PR: 1.25; 95% CI: 1.13–1.39), with education level below university degree (PR: 1.12; 95% CI: 1.08–1.32), living in rural areas (PR: 1.21; 95% CI: 1.08–1.36), attending sex parties (PR: 1.12; 95% CI: 1.03–1.33), using HIV-related biomedical prevention methods (PR: 1.31; 95% CI: 1.12–1.54), with STI diagnosis (PR: 1.22; 95% CI: 1.08–1.38) and with hepatitis A or B vaccination (PR: 4.56; 95% CI: 3.63–5.81 vs PR: 3.35; 95% CI: 2.53–4.44). Conclusions The HPV vaccination uptake among MSM in France was not satisfactory. It was higher among MSM benefitting from other vaccinations and biomedical preventive methods against HIV, suggesting a synergistic effect of the national preventive sexual health recommendations for MSM. Further efforts to improve HPV vaccination coverage targeting MSM are warranted.

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.

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.

Background: This study aimed to determine human papillomavirus (HPV) vaccine uptake and willingness to receive HPV vaccination among female college students, in China, and its associated factors. Methods: An online cross-sectional survey of female college students across the eastern, central, and western regions of China was undertaken between April and September 2019. Partial least squares structural equation modeling (PLS-SEM) was used to examine factors associated with the HPV vaccine uptake and willingness to receive the HPV vaccine. Results: Among the total 4220 students who participated in this study, 11.0% reported having been vaccinated against HPV. There are direct effects of indicators of higher socioeconomic status, older age (β = 0.084 and p = 0.006), and geographical region (residing in Eastern China, β = 0.033, and p = 0.024) on HPV vaccine uptake. Higher knowledge (β = 0.062 and p < 0.000) and perceived susceptibility (β = 0.043 and p = 0.002) were also predictors of HPV vaccine uptake. Of those who had not received the HPV vaccine, 53.5% expressed a willingness to do so. Likewise, social economic status indicators were associated with the willingness to receive the HPV vaccine. Total knowledge score (β = 0.138 and p < 0.001), both perceived susceptibility (β = 0.092 and p < 0.001) and perceived benefit (β = 0.088 and p < 0.001), and sexual experience (β = 0.041 and p = 0.007) had a positive and significant direct effect on the willingness to receive the HPV vaccine, while perceived barriers (β = −0.071 and p < 0.001) had a negative effect on the willingness to receive the HPV vaccine. Conclusions: Geographical region and socioeconomic disparities in the HPV vaccination uptake rate and willingness to receive the HPV vaccine provide valuable information for public health planning that aims to improve vaccination rates in underserved areas in China. The influence of knowledge and perceptions of HPV vaccination suggests the importance of communication for HPV immunization.

ObjectiveTo assess social patterns in human papillomavirus (HPV) vaccine coverage in a school-based, government-funded vaccination programme located within a single-payer universal healthcare system.DesignWe conducted a cross-sectional analysis of HPV vaccine uptake data for the 2013–2014 school year for 131 local authorities in England, and then evaluated the association between vaccine uptake and socioeconomic status at the aggregate level.Data sourcesHPV vaccination coverage data from Public Health England’s vaccine uptake guidance and the UK’s March 2011 Census.Main outcome measuresWe measured three-dose local authority-level vaccine series initiation to completion.ResultsWe found that in local authorities where there are more high-income families, the vaccination rate is lower than in local authorities with more low-income families. Local authorities with a higher percentage of whites, compared with non-whites, had higher HPV vaccination rates. Additionally, local authorities with more non-migrants had higher rates of vaccination. Local authorities with more education deprivation had higher rates of vaccination. Local authorities’ higher proportions of high-status occupations had worse vaccination coverage. In bivariate analyses across all the socioeconomic indicators, a 1 SD change in the indicators was associated with about a 2.25 percentage point decrease (for income, education and occupation) or increase (for race and migrant composition) in HPV dose coverage in the local authority. In multivariable analyses, only race remained as a significant predictor of HPV coverage at the local authority level.ConclusionsAcross all three doses, there are notable variations by socioeconomic status, with steep reverse gradients in three socioeconomic indicators. More quantitative and qualitative research needs to be conducted to determine the effects of the 2014 transition from a three-dose regimen to two-dose regimen on vaccination coverage, especially in groups that experience lower rates of vaccination.

Human papillomavirus (HPV) remains the most common sexually transmitted infection with a lifetime incidence of over 75%. Based on US data from the Centers for Disease Control and Prevention (CDC), 64% of invasive HPV-associated cancers are attributable to HPV 16 or 18 (65% for females; 63% males) and may be prevented by vaccination with either the quadrivalent or nonavalent HPV vaccine. Public HPV vaccination programs are now the norm for women aged 9-45 years and men aged 9-26 years in Canada. Yet, only recently have guidelines begun to consider vaccination of men older than 26 years of age. There now exist compelling reasons to recommend vaccination against HPV amongst males >26 years of age. Recognizing that the risks posed by HPV infection persist beyond 26 years of age, that the vaccination of men aged 26-45 years with HPV vaccine confers immunogenicity at levels demonstrably efficacious against HPV-related diseases, and that the Food and Drug Administration recently expanded the HPV vaccination to include older men, it is argued that HPV vaccination in men older than 26 years of age should be routinely recommended.

Background More than 90% of human papillomavirus (HPV)-related cancers could be prevented by widespread uptake of the HPV vaccine, yet vaccine use in the United States falls short of public health goals. Objective The purpose of this study was to describe the development, acceptability, and intention to use the mobile app Vaccipack, which was designed to promote uptake and completion of the adolescent HPV vaccine series. Methods Development of the mobile health (mHealth) content was based on the integrated behavioral model (IBM). The technology acceptance model (TAM) was used to guide the app usability evaluation. App design utilized an iterative process involving providers and potential users who were parents and adolescents. App features include a vaccine-tracking function, a discussion forum, and stories with embedded messages to promote intention to vaccinate. Parents and adolescents completed surveys before and after introducing the app in a pediatric primary care setting with low HPV vaccination rates. Results Surveys were completed by 54 participants (20 adolescents aged 11 to 14 years and 34 parents). Notably, 75% (15/20) of adolescents and 88% (30/34) of parents intended to use the app in the next 2 weeks. Acceptability of the app was high among both groups: 88% (30/34) of parents and 75% (15/20) of adolescents indicated that Vaccipack was easy to use, and 82% (28/34) of parents and 85% (17/20) of adolescents perceived the app to be beneficial. Higher levels of app acceptability were found among parents with strong intentions to use the app (P=.09; 95% CI –2.15 to 0.15). Conclusions mHealth technology, such as Vaccipack, may be an acceptable and nimble platform for providing information to parents and adolescents and advancing the uptake of important vaccines.

Introduction: Parents acquire information about human papillomavirus (HPV) vaccines online and encounter vaccine-critical content, especially on social media, which may depress vaccine uptake. Secondary analysis in a randomized trial of a Facebook-delivered adolescent health campaign targeting mothers with posts on HPV vaccination was undertaken with the aims of (a) determining whether the pre–post-change occurred in self-reports of the mothers on HPV vaccination of their adolescent daughters; (b) describing the comments and reactions to vaccine posts; (c) exploring the relationship of campaign engagement of the mothers assessed by their comments and reactions to posts to change in the self-reports of the mothers of HPV vaccination.Materials and Methods: Mothers of daughters aged 14–17 were recruited from 34 states of the US (n = 869). A social media campaign was delivered in two Facebook private groups that differed in that 16% of posts in one were focused on indoor tanning (IT) and 16% in the other, on prescription drug misuse, assigned by randomization. In both groups, posts promoted HPV vaccination (n = 38 posts; no randomization) and vaccination for other disease (e.g., influenza, n = 49). HPV and other vaccination posts covered the need for a vaccine, the number of adolescents vaccinated, how vaccines are decreasing the infection rates, and stories of positive benefits of being vaccinated or harms from not vaccinating. Guided by social cognitive theory and diffusion of innovations theory, posts were intended to increase knowledge, perceived risk, response efficacy (i.e., a relative advantage over not vaccinated daughters), and norms for vaccination. Some vaccination posts linked to stories to capitalize on identification effects in narratives, as explained in transportation theory. All mothers received the posts on vaccination (i.e., there was no randomization). Mothers completed surveys at baseline and 12- and 18-month follow-up to assess HPV vaccine uptake by self-report measures. Reactions (such as sad, angry) and comments to each HPV-related post were counted and coded.Results: Initiation of HPV vaccination (1 dose) was reported by 63.4% of mothers at baseline, 71.3% at 12-month posttest (pre/post p &lt; 0.001), and 73.3% at 18-month posttest (pre/post p &lt; 0.001). Completion of HPV vaccination (two or three doses) was conveyed by 50.2% of mothers at baseline, 62.5% at 12-month posttest (pre/post p &lt; 0.001), and 65.9% at 18-month posttest (pre/post p &lt; 0.001). For posts on HPV vaccines, 8.1% of mothers reacted (n = 162 total), and 68.4% of posts received a reaction (63.2% like; 13.2% love, 7.9% sad). In addition, 7.6% of mothers commented (n = 122; 51 unfavorable, 68 favorable, 1 neutral), and 50.0% of these posts received a comment. There were no differences in pre–post change in vaccine status by the count of reactions or comments to HPV vaccine posts (Ps &gt; 0.05). Baseline vaccination was associated with the valence of comments to HPV vaccine posts (7.2% of mothers whose daughters had completed the HPV series at baseline made a favorable comment but 7.6% of mothers whose daughters were unvaccinated made an unfavorable comment).Conclusion: Effective strategies are needed in social media to promote HPV vaccines and counter misinformation about and resistance to them. Mothers whose daughters complete the HPV vaccine course might be recruited as influencers on HPV vaccines, as they may be predisposed to talk favorably about the vaccine. Comments from mothers who have not been vaccinated should be monitored to ensure that they do not spread vaccine-critical misinformation. Study limitations included lack of randomization and control group, relatively small number of messages on HPV vaccines, long measurement intervals, inability to measure views of vaccination posts, reduced generalizability related to ethnicity and social media use, and use of self-reported vaccine status.Clinical Trial Registration:www.clinicaltrials.gov, identifier NCT02835807.

AimTo co-produce with young people an educational package about the human papillomavirus (HPV) vaccine that is tailored to increase vaccine uptake in schools and populations with lower uptake.IntroductionPersistent infection with HPV can result in cancers affecting men and especially women. From September 2019, the English-schools-based HPV vaccination programme was expanded to include young men (in addition to young women) aged 12–13 years. Some young people attending schools with lower uptake of the vaccine have unmet information needs. We hypothesise that mechanisms to address information needs and increase young people’s autonomy in consent procedures will result in higher uptake.Methods and analysisThe Medical Research Council’s framework for development and evaluation of complex interventions will inform intervention development. Recruitment of young people aged 12–15 years and key stakeholders (National Health Service commissioners, school staff, immunisation nurses and youth workers/practitioners) will be facilitated through existing links with healthcare organisations, schools and youth organisations in areas with lower uptake of the HPV vaccination programme. The proposed research will comprise three phases: (1) a rapid review of adolescent immunisation materials and preliminary qualitative interviews with young people and key stakeholders, (2) theory development and co-production of HPV vaccine communication materials through an iterative process with young people and (iii) testing delivery mechanisms and acceptability of the educational package in four schools with lower uptake.Ethics and disseminationThe University of Bristol’s Faculty of Health Sciences and London School of Hygiene and Tropical Medicine's Research Ethics Committees provided approvals for the study. A dissemination event for young people and key stakeholders and webinar with the National Immunisation Network will be organised. The study findings will be published in peer-reviewed journals and presented at conferences. Recommendations for a future larger scale study will be made.
