Acceptance of the Human Papillomavirus Vaccine among General Men and Men with a Same-Sex Orientation and Its Influencing Factors: A Systematic Review and Meta-Analysis. Vaccines (Basel) 2023; 12:16. [PMID: 38250829 PMCID: PMC10819436 DOI: 10.3390/vaccines12010016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 12/14/2023] [Accepted: 12/17/2023] [Indexed: 01/23/2024] Open
Abstract
The human papillomavirus (HPV) vaccine reduces the prevalence of genital warts and the cancers they are associated with in males. However, the vaccination of males has always been neglected. Here, we performed a meta-analysis to comprehend the acceptability of the HPV vaccine in men and the factors impacting vaccination intentions. We searched PubMed, Web of Science, Embase, Ovid, CNKI, and Wan Fang up to 5 July 2023 for studies that reported HPV vaccine acceptance among men. A random effects model was used to obtain the pooled acceptance rate, and subgroup analysis was performed. Then, the influencing factors of HPV vaccination in males were analyzed. A total of 57 studies with 32,962 samples were included in the analysis. The overall acceptance rate of the HPV vaccine in general men was 47.04% (95% confidence interval [95%CI]: 39.23-54.93%), and 62.23% (95% CI: 52.93-71.10%) among those whose sexual orientation contained men. HPV vaccine acceptance rates differed significantly between the two populations (p = 0.01). The population with a medical background (46.23%, 95% CI: 40.28-52.24%) was more willing to be vaccinated. In comparison to the employed population (66.93%, 95% CI: 48.79-82.81%) and the unemployed (68.44%, 95% CI: 52.82-82.23%), vaccination acceptance rates were lower among students (47.35%, 95% CI: 37.00-57.81%) (p = 0.04). The most significant barriers to vaccination were perceived low risk of infection for themselves (45.91%, 95% CI: 31.73-60.43%), followed by vaccine cost (43.46%, 95% CI: 31.20-56.13%). Moreover, the recommendations from medical professionals (60.90%, 95%CI: 44.23-76.37%) and sexual partners (60.09%, 95%CI: 27.11-88.67%) were significant factors in promoting vaccination. Overall, acceptance of the HPV vaccine among general men was at a lower level, despite being slightly higher among men with a same-sex orientation. Popularizing knowledge about diseases and vaccines, encouraging medical professionals to recommend vaccines to men, or reducing the cost of vaccines may promote HPV vaccination.

Tran PL, Leruste S, Sitthisone J, Humbert M, Gilhard X, Lazaro G, Chirpaz E, Boukerrou M, Bertolotti A. Understanding barriers and motivations to Papillomavirus vaccination in a middle school in Reunion Island. Eur J Obstet Gynecol Reprod Biol 2023; 285:17-23. [PMID: 37028117 DOI: 10.1016/j.ejogrb.2023.03.033] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 03/05/2023] [Accepted: 03/27/2023] [Indexed: 03/31/2023]
Abstract
BACKGROUND In Reunion Island, papillomavirus (HPV) vaccination coverage is low. A study encouraging vaccination in middle school showed low rate of participation. The main objective of the study was to understand barriers and motivations to HPV vaccination in populations yet sensitized to its benefits. METHODS The study focused on population around the intervention school where a health promotion program was conducted during school year 2020-2021. Semi-structured face-to-face interviews among children, children's parents, school staff, general practitioners (GP) and association members were conducted. A qualitative study was adopted using a grounded theory approach to obtain an in-depth understanding of issues pertaining to HPV vaccination. FINDINGS A total of 19 school staff members, 20 parents of middle school children, 39 children, 5 GPs and 3 association members were interviewed in May 2021. Anti-vaccination attitudes included: fear of serious adverse effects (such as fertility) due to poor knowledge, fear of encouraging sexuality among teenagers, mistrust towards scientists and the pharmaceutical industry and the negative impact from social networks. However, we found that the influence of the school, GP's and 'story-telling' study testimonials were crucial to invert the balance and motivate children's vaccination. INTERPRETATION Reproductive adverse events related to the HPV vaccine may be strongly perceived amongst our population, either regarding fertility or negative fetal effects; though Reunion island has 5% of pregnancies among teenagers. It is crucial to lift this taboo related to sexuality and encourage dialogue between children and their close social network. This better understanding of barriers and motivations will help us increase the impact of school-based HPV vaccination, which will be introduced in September 2023 in whole France.

Abstract
BACKGROUND Since the introduction of HPV vaccines, several studies have been conducted in different countries to assess HPV knowledge and vaccine acceptance. The aim of this study was to perform a systematic literature review to summarize results and identify factors associated with HPV knowledge and vaccine acceptance in adolescents and their parents and to compile the measurement tools used in the published research studies performed in European countries where HPV is licensed. METHODS A systematic literature review was conducted for studies published between January 1st 2006 and December 31st 2017. RESULTS Seventy non-interventional studies performed in 16 European countries met the inclusion criteria. Thirty-eight of them reported data on HPV knowledge and 40 reported data on HPV vaccine acceptance. Further, 51.8% of adolescents (range 0% to 98.6%) and 64.4% of parents (range 1.7% to 99.3%) knew about HPV infection. Insufficient information and safety concerns were the main barriers to vaccination acceptance. CONCLUSION HPV knowledge and vaccine acceptance are still modest and vary widely between studies across EU countries. Coordinated efforts should be made to provide the relevant population with information for informed decision-making about HPV vaccination.

Abstract
There is a high burden of cervical cancer in the Caribbean region, particularly in the Bahamas, yet there are few studies of Human Papillomavirus (HPV) and HPV vaccine in the region. The objective of this study was to assess the knowledge and awareness of HPV and the HPV vaccine among school-aged youth (15–18 years) living in the Bahamas. Cross-sectional data were obtained from the “Getting to Zero” HIV study in the Bahamas conducted in 2014/2015 (n = 1553). The questionnaire elicited information on knowledge of HPV and HPV vaccines, using previously validated scales. Data analysis included Chi-square tests and Mann Whitney U test. In this sample of school-aged youth, only 10.7% (146/1364) had ever heard of HPV. With respect to those who were sexually active (n = 685), only 10.7% had ever heard of HPV. For those who had heard of HPV, knowledge of HPV and HPV vaccines was assessed on an HPV Knowledge and HPV Vaccine Knowledge scale, respectively. There was no statistically significant difference in mean HPV knowledge score between males and females, or HPV vaccine knowledge scores, between males and females. There was a general lack of awareness of HPV and HPV vaccines among school-aged youth in the Bahamas. This is an important gap in the HPV vaccine strategy and cancer prevention, as this is the age at which most people acquire HPV. It emphasizes the importance of developing a careful implementation plan, with an evaluation of knowledge and attitudes, in order to have an effective HPV vaccine uptake.

Abstract
Awareness of HPV by the target population is an important determinant of vaccine acceptance. The aim of this study is to evaluate the awareness of HPV infection and acceptability of the HPV vaccines among Turkish college students. College students aged 18-30 who were attending a large public university in Ankara participated in this study. The participants were asked to complete a questionnaire to elicit demographic characteristics, awareness level of HPV and HPV vaccine, and willingness to be vaccinated. One thousand one hundred sixty students responded to the invitation email and completed the questionnaire. The mean scores of female students about HPV and HPV vaccine were 7.1/15 and 3.6/9, respectively, while these scores were 7.9/15 and 3.4/9 among male students, respectively. While 51 % percent of female and 33.5 % of male students had heard of HPV and 32.8 % and 18 % of them had heard of HPV vaccine, respectively, only 1.5 % of female and 0.4 % of male students had been vaccinated against HPV. A total of 507 students (43.7 %) had previously heard of HPV. Only 309 (26.6 %) of the participants had previously heard of the HPV vaccine, and 45.1 % of the students were willing to receive HPV vaccination. The main predictors for willingness to be vaccinated were the following: sexual experience, sexual behavior, past history of sexually transmitted infection (STI), and knowledge about HPV and HPV vaccine. Higher awareness levels of HPV and HPV vaccine are significantly related to greater willingness to be vaccinated, and the main reasons for rejecting the vaccine were insufficient information about the vaccine and possible unknown side effects.

Abstract
OBJECTIVES The success of vaccination strategies depends in part on population perceptions of benefits and risks of vaccines and related confidence in vaccination. Better knowledge of public concerns about vaccines and what is driving them is needed to inform vaccination strategies and communications. This literature reviewer examined studies on vaccine and vaccination risk perceptions and concerns across European populations. METHODS A systematic literature review was conducted to identify studies published between 2004 and 2014 in Europe. A descriptive analysis was performed. FINDINGS A total of 145 articles were selected, most of which were conducted in the UK, the Netherlands and France and studied seasonal influenza, HPV and pandemic influenza vaccination. Across all countries and vaccines, the primary area of concern was vaccine safety, followed by perceptions of low likelihood of contracting vaccine-preventable diseases (VPDs), perceived low severity of VPDs, beliefs that vaccines do not work, and overall lack of information. Concerns were found to be vaccine-, country- and population-specific. CONCLUSION In addition to identifying concerns about vaccination in Europe, this study confirmed the notion that individuals have many safety concerns about vaccination and often believe that the risks of vaccination outweigh their benefits. More research needs to be conducted to explore the impact of different types of communication strategies, which would frame the benefits of vaccination as well as risks of not vaccinating. Strategies to better inform public perceptions of vaccines should include the provision of unbiased, comprehensive information tailored to population information needs, and delivered using multiple and new communication technologies such as social media.

Abstract
OBJECTIVES To explore predictors of university students' intention to receive a recommended vaccine and the main sources of vaccine-related information accessed by university students. SETTING Participants were recruited from University College London (UK) in summer 2015. PARTICIPANTS 177 university students participated. The majority of participants were female (58%), White (68%) and had no religion (58%). Participants were aged 18 to 42 (mean age=23.6). PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome measures included vaccine attitude, perceived subjective norm, perceived behavioural control, perceived self-efficacy, past receipt of recommended childhood vaccines, perceived adverse reaction to past vaccination and needle fear. As a secondary outcome sources of vaccine-related information were assessed. RESULTS Students classified as high intenders were more likely to have received all recommended childhood vaccines (OR 3.57; 95% CI 1.21 to 10.59; p=0.022), be less afraid of needles (OR 2.44; 95% CI 1.12 to 5.36; p=0.026) and to have lived in the UK until at least the age of 4 compared with those not living in the UK until at least the age of 4 (OR 0.39; 95% CI 0.18 to 0.83; p=0.015) and those who lived both in the UK and elsewhere (OR 0.42; 95% CI 0.04 to 4.06; p=0.424). The multivariable model explained 25.5% of variance in intention to receive a recommended vaccine. The internet was the most commonly reported source of vaccination information. CONCLUSIONS Findings provide an indication of the factors that may need to be addressed by interventions aiming to increase uptake of recommended vaccines in a university population. Future research is recommended using a prospective cohort design.

Abstract
In Canada, the human papillomavirus (HPV) vaccine is licensed and recommended for females and males. Although all Canadian jurisdictions fund school-based HPV vaccine programs for girls, only six jurisdictions fund school-based HPV vaccination for boys. The research aimed to analyze the factors that underpin government decisions to fund HPV vaccine for boys using a theoretical policy model, Kingdon's Multiple Streams framework. This approach assesses policy development by examining three concurrent, but independent, streams that guide analysis: Problem Stream, Policy Stream, and Politics Stream. Analysis from the Problem Stream highlights that males are affected by HPV-related diseases and are involved in transmitting HPV infection to their sexual partners. Policy Stream analysis makes clear that while the inclusion of males in HPV vaccine programs is suitable, equitable, and acceptable; there is debate regarding cost-effectiveness. Politics Stream analysis identifies the perspectives of six different stakeholder groups and highlights the contribution of government officials at the provincial and territorial level. Kingdon's Multiple Streams framework helps clarify the opportunities and barriers for HPV vaccine policy change. This analysis identified that the interpretation of cost-effectiveness models and advocacy of stakeholders such as citizen-advocates and HPV-affected politicians have been particularly important in galvanizing policy change.

Abstract
Assessing physicians' experiences in HPV vaccine recommendation and delivery to adolescent boys is essential to providing an understanding of the issues of vaccine acceptance and an insight for policymakers to enhance HPV vaccinations among adolescent boys. Between January and April 2014 a mail survey was conducted using physicians in Malaysia known to provide either one or both HPV vaccine (Gardasil and Cervarix) immunisation services. A total of 357 completed questionnaires were received (response rate 22.5%). Of these, 335 physicians see adolescent boys aged 11 to 18 years old in their practice. Only 26.3% (n = 88) recommended the HPV vaccine to these boys. A total of 46.6% (n = 41) have successfully given the HPV vaccine to adolescent boys. A lack of proper guidelines from the health authorities regarding the recommendation of HPV vaccine to the boys (37.2%) and a lack of awareness of the availability of the vaccine for boys (32.8%) were the most commonly cited reasons for non-recommendation. Impact statement Recommending the HPV vaccine for adolescent boys remains a challenge for physicians. Our study provides evidence of challenges and barriers faced by Malaysian physicians who recommend the HPV vaccines (Gardasil and Cervarix) in their practices. In this study, physicians reported HPV vaccine uptake by adolescent boys was very poor. A lack of proper guidelines from the health authorities regarding the recommendation of HPV vaccine to boys and a lack of awareness of the availability of the vaccine for boys were the most commonly cited reasons for non-recommendation. Physicians viewed that support and encouragement from the health authorities are needed to promote the recommendation of the HPV vaccine to adolescent boys. Physicians were also of the opinion that the lay public should be educated about the availability of the HPV vaccine for boys, and its benefits, safety and efficacy, and the high susceptibility of boys to getting HPV infections. The findings provide insights that could be helpful to policymakers or high-level decision-makers of the potential strategies to enhance HPV uptake among adolescent boys.

Abstract
OBJECTIVES To examine the impact of the national human papillomavirus (HPV) vaccination program (available to girls and women [12-26 years] since 2007 and to boys [12-15 years] since 2013) on the number of diagnoses of genital warts in Australian Aboriginal and Torres Strait Islander (Indigenous) people. DESIGN, SETTING, PARTICIPANTS Analysis of routinely collected data from patients attending 39 sexual health clinics (SHCs) in the Genital Warts Surveillance Network for the first time.Major outcome: The average annual proportion of Indigenous and non-Indigenous SHC patients diagnosed with genital warts during the pre-vaccination (2004-2007) and vaccination periods (2008-2014), stratified by age group and sex. RESULTS 7.3% of the 215 599 Australian-born patients with known Indigenous status and seen for the first time at participating SHCs during 2004-2014 were Indigenous Australians. The average proportion of female Indigenous patients diagnosed with warts was lower during the vaccination period than during the pre-vaccination period (in those under 21, summary rate ratio [SRR], 0.12; 95% CI, 0.07-0.21; P < 0.001); in 21-30-year olds: SRR, 0.41; 95% CI, 0.27-0.61; P < 0.001); there was no significant difference for women over 30 (SRR, 0.84; 95% CI, 0.51-1.36; P = 0.47). The proportion of male Indigenous heterosexual SHC patients under 21 diagnosed with warts was also lower during the vaccination period (SRR, 0.25; 95% CI, 0.12-0.49; P < 0.001), with no significant changes among older Indigenous men over 30. CONCLUSIONS There were marked declines in the proportions of diagnoses of genital warts in young Indigenous women and men attending SHCs after the introduction of the HPV vaccination program. If high levels of HPV vaccine coverage are sustained, HPV-related cancer rates should also decline.

Abstract
This study assessed knowledge and attitudes about Human papillomavirus (HPV) and the relative vaccination and their determinants in a sample of young males. The survey was conducted between January and April 2015 among a sample of 1000 males aged between 14-24 y in the geographic area of Naples and Caserta, Italy. The 54.9% of the participants reported of having heard about the HPV infection. Those who were aware about the availability of the vaccine, who reported the first vaginal sexual encounter before the 18 y and at least at 18 y compared to those who had not had a complete sexual intercourse, who had undergone a health checkup in the last year, and who had received information about the HPV vaccine by physicians had a significant higher knowledge about the HPV infection. The 58.2% reported that they would be willing to receive the HPV vaccine. Those younger, who reported the first vaginal sexual encounter at least at 18 y, who agreed that male should receive the vaccine, who knew that both males and females can acquire the infection, and who agreed that the vaccine is an important preventive intervention, expressed more positive attitude toward willingness to receive the vaccine. More information about the HPV vaccine were required by those who agreed that the vaccine is an important preventive intervention, who reported the first vaginal sexual encounter at least at 18 y, who have had only one partner in the last year compared to students who had no partner, and who had received information about the vaccine by physicians. This study highlights a need for improved education of young males of the HPV infection and the associated diseases and about the benefit of the vaccination.

Abstract
INTRODUCTION Sexually transmitted infections (STIs) are major causes of medical and psychological problems globally, while adolescents in South Korea have recently shown rapid changes in sexual behaviors. AIMS We aimed to examine the association between the age of first sexual intercourse and the experience of STIs among adolescents. Additionally, in which specific time period would more likely to get infected from sexual intercourse. METHODS We used data from the 2007-2013 Korea Youth Risk Behavior Web-based Survey. Only adolescents with sexual intercourse experience (N = 22,381) were included, and multiple logistic regression analysis was performed. MAIN OUTCOME MEASURES One dichotomized measure and one continuous measure were assessed: (i) STIs experience (defined as having had STIs); and (ii) association between STIs experience and absolute age gap (defined as temporal differences between secondary sexual character emergence age and first sexual intercourse age). RESULTS Approximately 7.4% of boys and 7.5% of girls reported had STI. For both boys and girls, the chance of experiencing STIs increased as the age of first sexual intercourse decreased (boys: before elementary school [age 7 or under]: odds ratio [OR] = 10.81, first grade [age 7 or 8]: OR = 4.44, second grade [age 8 or 9]: OR = 8.90, fourth grade [age 10 or 11]: OR = 7.20, ninth grade [age 15 or 16]: OR = 2.31; girls: before elementary school: OR = 18.09, first grade: OR = 7.26, second grade: OR = 7.12, fourth grade: OR = 8.93, ninth grade: OR = 2.74). The association between the absolute age gap and STI experience was examined additionally (boys: OR = 0.93, girls: OR = 0.87). CONCLUSIONS This study shows that earlier initiation of sexual intercourse increases the odds of experiencing STIs. Also as the age gap gets shorter, the odds of experiencing STIs increase. Our study suggests that it is important to consider the time period of first sexual intercourse and to reinforce a monitoring system along with the development of other preventive strategies.

Abstract
STUDY OBJECTIVE This study aimed to determine the willingness of parents to allow their sons and/or daughters aged 10-13 years to be vaccinated for human papillomavirus (HPV). DESIGN, SETTING, AND PARTICIPANTS This was a descriptive study conducted in an elementary school to recruit students' parents into the study. The sample consisted of 368 (69.1%) parents of children aged 10-13 years who were willing to participate in the study as a couple. INTERVENTIONS Questionnaire-based data were collected from the couples. MAIN OUTCOME MEASURES Prior information regarding HPV and vaccination and the opinions of parents of children aged 10-13 about HPV vaccination for their daughter or son. RESULTS Only 26.9% of mothers and 25.0% of fathers claimed to be aware of HPV, and only 24.5% of mothers and 21.2% of fathers claimed to be aware of its vaccine. If the vaccine were available in Turkey, 21.6% of mothers and 22.4% of fathers would be willing to vaccinate their sons; although the vaccine for girls is available in Turkey, only 14.4% of mothers and 15.5% of fathers were willing to vaccinate their daughters. CONCLUSIONS Few participants reported knowing about the HPV vaccine, while far fewer intended to vaccinate their daughters and sons against the infection. Both males and females should be informed about HPV and its vaccine, and initiatives to increase both awareness and the information of health care professionals should be encouraged.

Abstract
Background Human papillomavirus (HPV) is a common sexually transmitted virus that can lead to severe diseases in both women and men. Today, HPV vaccination is offered to females only across Europe. We aimed to examine parental attitudes to HPV vaccination of their sons given brief information about HPV in both genders. Methods A literature study on acceptability of male HPV vaccination was carried out to inform the construction of a study questionnaire. Following up on a Danish study from 2012, this questionnaire was applied in 1837 computer assisted interviews with parents of sons in the UK, Germany, France and Italy. In each country, the parents were representative in terms of geographical dispersion, city size and age of sons in the household. The applied questionnaires took the varying vaccination policies and delivery systems into account. The data were analysed pooled and for each country using significant statistical tests (chi-2) with a 95 % confidence interval. Results Approximately ¾ of parents in the UK, Germany and Italy were in favour of HPV vaccination of their sons. In France, this applied to 49 % of respondents. Favourable parents wanted to protect their sons from disease and found gender equality important. Parents in doubt about male HPV vaccination needed more information about HPV diseases in men and male HPV vaccination; Rejecting parents were generally sceptical of vaccines and feared vaccination side-effects. Parents in countries with active vaccination policies (UK and Italy) tended to trust the importance of national vaccination programmes. Parents in countries with passive vaccination strategies (Germany and France) had greater need for information from health care professionals (HCP) and public health authorities. Conclusion Given brief information about HPV in both genders, parental acceptance of HPV vaccination of sons is as high as acceptance levels for girls. All parents should be informed about HPV to make informed decisions about HPV vaccination for their children. There is a need for joint efforts from public health authorities and HCPs to provide parents with such information.

Abstract
BACKGROUND This study aimed to determine the awareness among fifth-grade girls and boys of sexually transmitted diseases (STDs), cancer, and human papillomavirus (HPV), and to determine the factors associated with intention to obtain the HPV vaccination. METHODS A quasi experimental design was employed with Korean fifth-grade students as the subjects for this study (n=117). Prior to providing HPV education, the awareness and health beliefs regarding STDs and cancer prevention were assessed according to gender. After 2 hours of HPV education, gender comparisons were made with respect to the awareness and health beliefs, HPV knowledge, and intention to obtain the HPV vaccination, and the factors associated with that intention. RESULTS Prior to the 2hours education session, only two boys knew that HPV is a virus. There were significant gender differences with respect to responses to the statements "STD is preventable" (χ(2)=8.76, p=0.013) and "cancer is preventable" (χ(2)=6.37, p=0.041), and concerns about the pain associated with vaccine injection (z=-2.44, p=0.015). After HPV education, there were no significant gender differences in HPV knowledge and intention to obtain the HPV vaccination. Awareness that "HPV vaccine can prevent cervical cancer" was significantly related to intention to obtain the HPV vaccine among both boys and girls. CONCLUSIONS Increased HPV knowledge could positively influence the intention to obtain the HPV vaccination among youth. Thus, HPV education at elementary school would be helpful to make students aware of HPV and the importance of HPV prevention.

Abstract
PURPOSE To measure HPV vaccine acceptance among unvaccinated adolescent males and parents and correlate acceptance with knowledge, awareness, and personal experience. METHODS Adolescent males ages 11-21 years old and their parents completed questionnaires measuring attitudes and knowledge about HPV vaccination and personal experience. Acceptance was defined as wanting the vaccine and conditional acceptance as wanting the vaccine if it would protect against genital warts or cervical cancer. RESULTS Adolescent (n=154) and parent (n=121) vaccine acceptance was low (16% and 34%, respectively); however, conditional acceptance was higher. While adolescents had similar conditional acceptance for a vaccine against genital warts and cervical cancer, parents reported higher conditional acceptance for protection against genital warts. Independent predictors of acceptance included personal experience and demographic variables. CONCLUSIONS HPV vaccine acceptance among adolescents and parents was low. Conditional acceptance levels highlight the importance of education about a few important benefits of HPV vaccination, which may increase vaccination rates.

Abstract
This paper provides a consolidated overview of public and healthcare professionals' attitudes towards vaccination in Europe by bringing together for the first time evidence across various vaccines, countries and populations. The paper relies on an extensive review of empirical literature published in English after 2009, as well as an analysis of unpublished market research data from member companies of Vaccines Europe. Our synthesis suggests that hesitant attitudes to vaccination are prevalent and may be increasing since the influenza pandemic of 2009. We define hesitancy as an expression of concern or doubt about the value or safety of vaccination. This means that hesitant attitudes are not confined only to those who refuse vaccination or those who encourage others to refuse vaccination. For many people, vaccination attitudes are shaped not just by healthcare professionals but also by an array of other information sources, including online and social media sources. We find that healthcare professionals report increasing challenges to building a trustful relationship with patients, through which they might otherwise allay concerns and reassure hesitant patients. We also find a range of reasons for vaccination attitudes, only some of which can be characterised as being related to lack of awareness or misinformation. Reasons that relate to issues of mistrust are cited more commonly in the literature than reasons that relate to information deficit. The importance of trust in the institutions involved with vaccination is discussed in terms of implications for researchers and policy-makers; we suggest that rebuilding this trust is a multi-stakeholder problem requiring a co-ordinated strategy.

Abstract
OBJECTIVE Human papillomavirus (HPV) vaccine uptake in many countries has been sub-optimal. We examine several issues associated with non-vaccination that have received particular attention, including fears about sexual risk compensation, concerns about vaccine safety, inadequate vaccination recommendations by health care providers (HCPs), and distrust due to the perceived "newness" of HPV vaccines. METHODS Selective review of behavioral and social science literature on HPV vaccine attitudes and uptake. RESULTS There is no evidence of post-vaccination sexual risk compensation, HPV vaccines are quite safe, and they can no longer be considered "new". Nonetheless, research findings point to these issues and, most importantly, to the failure of HCPs to adequately recommend HPV vaccine as major drivers of non-vaccination. CONCLUSION Most fears related to HPV vaccine are more related to myth than reality. In the absence of major health policy initiatives, such as those implemented in Canada, the U.K., and Australia, a multi-level, multi-faceted approach will be required to achieve high rates of HPV vaccination. It will be essential to focus on the education of HCPs regarding indications for HPV vaccination and approaches to communicating most effectively with parents and patients about the safety and benefits of vaccination and the risks associated with non-vaccination.

Abstract
BACKGROUND In South Africa, the prevalence of oncogenic Human Papillomavirus (HPV) may be as high as 64%, and cervical cancer is the leading cause of cancer-related death among women. The development of efficacious prophylactic vaccines has provided an opportunity for primary prevention. Given the importance of psycho-social forces in vaccine uptake, we sought to elucidate factors influencing HPV vaccination among a sample of low-income South African adolescents receiving the vaccine for the first time in Soweto. METHODS The HPV vaccine was introduced to adolescents in low-income townships throughout South Africa as part of a nationwide trial to understand adolescent involvement in future vaccine research targeting human immunodeficiency virus (HIV). We performed in-depth semi-structured interviews with purposively-sampled adolescents and their care providers to understand what forces shaped HPV vaccine uptake. Interviews were recorded, transcribed, translated, and examined using thematic analysis. RESULTS Of 224 adolescents recruited, 201 initiated the vaccine; 192 (95.5%) received a second immunization; and 164 (81.6%) completed three doses. In our qualitative study of 39 adolescent-caregiver dyads, we found that factors driving vaccine uptake reflected a socio-cultural backdrop of high HIV endemnicity, sexual violence, poverty, and an abundance of female-headed households. Adolescents exercised a high level of autonomy and often initiated decision-making. Healthcare providers and peers provided support and guidance that was absent at home. The impact of the HIV epidemic on decision-making was substantial, leading participants to mistakenly conflate HPV and HIV. CONCLUSIONS In a setting of perceived rampant sexual violence and epidemic levels of HIV, adolescents and caregivers sought to decrease harm by seeking a vaccine targeting a sexually transmitted infection (STI). Despite careful consenting, there was confusion regarding the vaccine's target. Future interventions promoting STI vaccines will need to provide substantial information for participants, particularly adolescents who may exercise a significant level of autonomy in decision-making.

Abstract
Background Chlamydia and genital human papillomavirus (HPV) are the two most common sexually transmitted infections (STIs) among teens and young adults in industrialised countries. The majority of adolescents, however, have limited or no knowledge of these infections. Within the context of a cross-sectional survey on awareness and knowledge of sexually transmitted infections, secondary school students attending the 8th grade and above in Bremen and Bremerhaven, two cities in northern Germany, were asked to rate the risk of peers to get infected with HIV, HPV or chlamydia. Methods Between October and December 2011, students aged 12–20 years completed an anonymous, self-administered questionnaire at their school. In addition to answering questions on awareness and knowledge of sexually transmitted infections, all students were also asked to rate the risk of peers to get infected with HIV, HPV or chlamydia. Furthermore, those reporting ever having sexual intercourse were asked to rate their own risk of getting infected with each of the three infections. Results 1,148 students, 55% female, completed the questionnaire. 27% of the students reported having had sexual intercourse. 68% of all students rated the risk of same-aged students to get infected with HIV/AIDS as high/medium. The corresponding proportions for HPV and chlamydia were 19 and 25% respectively. Those reporting ever having sexual intercourse generally perceived their own risk of getting infected with HIV, chlamydia or HPV as lower than that of their peers. Conclusion Generally, the risk of getting infected with HIV was perceived as being higher than that of getting infected with HPV or chlamydia, most likely due to the fact that the students were more aware of HIV than of the other two infections. Efforts should be made to improve awareness and knowledge of HPV and chlamydia among school going adolescents, and to make them realize that these are common infections that are preventable.

[PMID: 23241217 PMCID: PMC3547753 DOI: 10.1186/1471-2431-12-192] [Citation(s) in RCA: 62] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2012] [Accepted: 12/11/2012] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Licensed for use in males in 2009, Human Papillomavirus (HPV) vaccination rates in adolescent males are extremely low. Literature on HPV vaccination focuses on females, adult males, or parents of adolescent males, without including adolescent males or the dynamics of the parent-son interaction that may influence vaccine decision-making. The purpose of this paper is to examine the decision-making process of parent-son dyads when deciding whether or not to get vaccinated against HPV. METHODS Twenty-one adolescent males (ages 13-17), with no previous HPV vaccination, and their parents/guardians were recruited from adolescent primary care clinics serving low to middle income families in a large Midwestern city. Dyad members participated in separate semi-structured interviews assessing the relative role of the parent and son in the decision regarding HPV vaccination. Interviews were recorded, transcribed, and coded using inductive content analysis. RESULTS Parents and sons focused on protection as a reason for vaccination; parents felt a need to protect their child, while sons wanted to protect their own health. Parents and sons commonly misinterpreted the information about the vaccine. Sons were concerned about an injection in the penis, while some parents and sons thought the vaccine would protect them against other sexually transmitted infections including Herpes, Gonorrhea, and HIV. Parents and sons recalled that the vaccine prevented genital warts rather than cancer. The vaccine decision-making process was rapid and dynamic, including an initial reaction to the recommendation for HPV vaccine, discussion between parent and son, and the final vaccine decision. Provider input was weighed in instances of initial disagreement. Many boys felt that this was the first health care decision that they had been involved in. Dyads which reported shared decision-making were more likely to openly communicate about sexual issues than those that agreed the son made the decision. CONCLUSION Parents and sons play an active role in the decision-making process, with an individual's role being influenced by many factors. The results of this study may be used to guide the messages presented by clinicians when recommending the HPV vaccine, and future vaccine uptake interventions.
