Abstract
OBJECTIVE The human papillomavirus (HPV) vaccine has been proven effective in preventing HPV-related cancer. However, vaccination uptake in the United States remains unacceptably low. The aim of this study is to determine whether residents' HPV vaccination status, demographics, or residency training setting are predictive of vaccination prescribing practices. METHODS This was an anonymous, IRB-approved, opt-in survey of OBGYN, Family Medicine, and Pediatric residents. Using the National Residency Match Program Web site, surveys were sent to program directors requesting their residents' participation. Demographics, practice settings, HPV vaccination status, reasons for being inappropriately vaccinated, and resident vaccination-prescribing practices were analyzed. RESULTS A total of 853 residents participated. A total of 56.7% of respondents were fully vaccinated against HPV. The most common reasons for being unvaccinated were as follows: age (51.7%, n = 122), monogamous (30.9%, n = 73), do not believe it works (22.5%, n = 53), and affordability/insurance did not cover (14.4%, n = 34). Residents working in an urban setting were more likely to be vaccinated than those in suburban (odds ratio [OR] = 1.93, 95% confidence interval [CI], 1.364-3.229, p < .001) or rural (OR = 2.08, 95% CI 1.461-3.359, p 0.01) settings. Males were less likely than females (OR = 0.90, 95% CI 0.702-0.997, p < .001) to be vaccinated. Single residents were more likely to be vaccinated than married (OR = 2.56, 95% CI 2.444-2.704, p < .001) or divorced (OR = 2.15, 95% CI 1.822-3.264, p 0.21) residents. Vaccinated residents were more likely to recommend HPV vaccination to their patients than those who were unvaccinated (OR = 1.83, 95% CI 1.321-2.548, p .004). CONCLUSIONS A significant portion of Family Medicine, Pediatrics, and OBGYN residents have not received appropriate vaccination against HPV. Vaccination is highest among residents who identify as female, single, or working in urban settings. Vaccinated residents were also found to be almost 2 times as likely to recommend vaccination to their patients. As such, our data suggest that targeted provider education is needed to increase vaccination rates for both trainees and their patients.

[PMID: 38932417 PMCID: PMC11209485 DOI: 10.3390/vaccines12060689] [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: 04/21/2024] [Revised: 06/11/2024] [Accepted: 06/15/2024] [Indexed: 06/28/2024] Open
Abstract
Human papillomavirus (HPV) is a prevalent cause of mucosal and cutaneous infections and underlying conditions ranging from benign warts to anogenital and oropharyngeal cancers affecting both males and females, notably cervical cancer. Cervical cancer is the fourth leading cause of cancer deaths among women globally and is the most impactful in low- and middle-income countries (LMICs), where the costs of screening and licensed L1-based HPV vaccines pose significant barriers to comprehensive administration. Additionally, the licensed L1-based HPV vaccines fail to protect against all oncogenic HPV types. This study generated three independent lots of an L2-based target antigen (LBTA), which was engineered from conserved linear L2-protective epitopes (aa11-88) from five human alphapapillomavirus genotypes in E. coli under cGMP conditions and adjuvanted with aluminum phosphate. Vaccination of rabbits with LBTA generated high neutralizing antibody titers against all 17 HPV types tested, surpassing the nine types covered by Gardasil®9. Passive transfer of naïve mice with LBTA antiserum revealed its capacity to confer protection against vaginal challenge with all 17 αHPV types tested. LBTA shows stability at room temperature over >1 month. Standard in vitro and in vivo toxicology studies suggest a promising safety profile. These findings suggest LBTA's promise as a next-generation vaccine with comprehensive coverage aimed at reducing the economic and healthcare burden of cervical and other HPV+ cancers in LMICs, and it has received regulatory approval for a first-in-human clinical study (NCT05672966).

Abstract
Background The human papillomavirus (HPV) vaccine is an underutilized cancer control practice in the United States. Although individual contextual factors are known to impact HPV vaccine coverage rates, the impact of macro-level elements are still unclear. The aim of this analysis was to use HPV vaccination rates to explore the underuse of an evidence-based cancer control intervention and explore broader-level correlates influencing completion rates. Methods A comprehensive database was developed using individual-level date from the National Immunization Survey (NIS)-Teen (2016) and state-level data collected from publically available sources to analyze HPV vaccine completion. Multi-level logistic models were fit to identify significant correlates. Level-1 (individual) and level-2 (state) correlates were fitted to a random intercept model. Deviance and AIC assessed model fit and sampling weights were applied. Results The analysis included 20,495 adolescents from 50 U.S. states and the District of Columbia. Teen age, gender, race/ethnicity, and maternal education were significant individual predictors of HPV completion rates. Significant state-level predictors included sex education policy, religiosity, and HPV vaccine mandate. States with the lowest HPV coverage rates were found to be conservative and highly religious. Little variation in vaccine exemptions and enacted sex and abstinence education polices were observed between states with high and low HPV vaccine coverage suggesting various contextual and situational factors impact HPV vaccine completion rates. Conclusions Given that gender, religiosity, political ideology, and education policies are predictors of HPV vaccine completion, the interaction and underlying mechanism of these factors can be used to address the underutilization of the HPV vaccine.

PLoS One 2018; 13:e0198615. [PMID: 29912883 PMCID: PMC6005511 DOI: 10.1371/journal.pone.0198615] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2017] [Accepted: 05/22/2018] [Indexed: 11/20/2022] Open
Abstract
Objectives The highly infectious human papillomavirus (HPV) causes both genital warts and cervical cancer in women. In 2009, the prevalence of genital warts in Hong Kong was 203.7 per 100,000 person-years. Cervical cancer, more seriously, was the eight most common cancer among women and girls in Hong Kong, accounting for 2.3% of all new cancer cases in females in 2014. Cervical cancer is a significant global public health problem and HPV is a major risk factor leading to the development of cervical cancer. HPV is also the most common sexually transmitted disease among university students. This is the first study to examine the acceptability of HPV vaccines and associations with perceptions related to HPV and HPV vaccines among the male baccalaureate student population locally. Methods A self-administrative cross-sectional survey was used to assess whether male baccalaureate students from eight local Hong Kong universities intended to be immunized for HPV. The study also asked questions concerning how its subjects perceived HPV and HPV vaccines using the Health Belief Model. Data collection spanned from June to September 2015. A multiple stepwise regression model was used to examine associations between cognitive factors and subjects’ intention to take up the HPV vaccine. Results A total of 1,004 (83.7%) students aged 18 and 26 participated in this study. 23.3% found vaccinating for HPV acceptable, a level correlating with a number of indicators. Subjects were more likely to find vaccinating acceptable if 1) they knew something about HPV vaccines; 2) they understood that men were susceptible to infection by HPV; 3) they realised they could benefit by HPV vaccination, and 4) they were aware of the arguments for and against HPV vaccination, as disseminated by either the media or peers. Conclusions HPV remains a significant public health concern in Hong Kong and China more broadly. This study’s findings show a disconnect between the perceived and actual risk of being infected with the HPV vaccine among male baccalaureate students. This disconnect may be bridged by informing young men of the benefits of their being vaccinated against HPV, by removing the psychological and financial barriers that prevent them from taking up the vaccine and by improving how primary healthcare providers motivate them to get immunized.

Using an Implementation Research Framework to Identify Potential Facilitators and Barriers of an Intervention to Increase HPV Vaccine Uptake. JOURNAL OF PUBLIC HEALTH MANAGEMENT AND PRACTICE 2018; 23:e1-e9.

Abstract
BACKGROUND Although the incidence of cervical cancer has been decreasing in the United States over the last decade, Hispanic and African American women have substantially higher rates than Caucasian women. The human papillomavirus (HPV) is a necessary, although insufficient, cause of cervical cancer. In the United States in 2013, only 37.6% of girls 13 to 17 years of age received the recommended 3 doses of a vaccine that is almost 100% efficacious for preventing infection with viruses that are responsible for 70% of cervical cancers. Implementation research has been underutilized in interventions for increasing vaccine uptake. The Consolidated Framework for Implementation Research (CFIR), an approach for designing effective implementation strategies, integrates 5 domains that may include barriers and facilitators of HPV vaccination. These include the innovative practice (Intervention), communities where youth and parents live (Outer Setting), agencies offering vaccination (Inner Setting), health care staff (Providers), and planned execution and evaluation of intervention delivery (Implementation Process). METHODS Secondary qualitative analysis of transcripts of interviews with 30 community health care providers was conducted using the CFIR to code potential barriers and facilitators of HPV vaccination implementation. RESULTS All CFIR domains except Implementation Process were well represented in providers' statements about challenges and supports for HPV vaccination. CONCLUSION A comprehensive implementation framework for promoting HPV vaccination may increase vaccination rates in ethnically diverse communities. This study suggests that the CFIR can be used to guide clinicians in planning implementation of new approaches to increasing HPV vaccine uptake in their settings. Further research is needed to determine whether identifying implementation barriers and facilitators in all 5 CFIR domains as part of developing an intervention contributes to improved HPV vaccination rates.

Abstract
The purpose of this study was to examine human papillomavirus (HPV) and HPV vaccine knowledge, attitudes, and uptake in college students and to identify factors associated with vaccination status utilizing the Precaution Adoption Process Model (PAPM). The sample included 383 undergraduates from a public university who participated in February and March 2015. Students were emailed an anonymous online survey assessing knowledge, attitudes, and perceptions related to HPV and HPV vaccination, as well as their stage in the PAPM regarding vaccination completion. Significantly more females (47.3%) than males (15.8%) were vaccinated. While most students had basic knowledge of HPV, they had low perceptions of their susceptibility to contract HPV. Most unvaccinated students were in the early stages of decision-making related to vaccination. Campus health centers have an opportunity to increase HPV vaccination rates. This study indicates that students need prompts from providers, as well as education regarding susceptibility to HPV.

Abstract
OBJECTIVE The Advisory Committee on Immunization Practices recommends routine human papillomavirus (HPV) vaccination for female adolescents aged 11 to 12 years, yet vaccination rates remain low. We conducted a qualitative study to understand English- and Spanish-speaking parents' reasons for noninitiation or noncompletion of the HPV vaccine series for their daughters. METHODS Parents of female adolescents aged 12 to 15 years who had not initiated or not completed the HPV vaccine series were identified through administrative data in 2 large urban safety net health care systems in Colorado. Focus groups and in-depth interviews were conducted with English-speaking parents and in-depth interviews were conducted with Spanish-speaking parents. All data were recorded, transcribed, and analyzed for thematic content by experienced analysts using established qualitative content analysis techniques. RESULTS Forty-one parents participated in the study. Thirty parents participated in individual interviews and 11 parents participated in 1 of 2 focus groups. The most common reasons for noninitiation and noncompletion among English-speaking parents included a low perceived risk of HPV infection, vaccine safety concerns, and distrust of government and/or medicine. In contrast, Spanish-speaking parents most often reported that providers had either not encouraged initiation of the HPV vaccine series or had not explained the necessity of completing the series. Some noninitiating parents, particularly Spanish-speaking ones, also cited concerns that vaccination would encourage sexual activity. CONCLUSIONS The reasons for noninitiation and noncompletion of the HPV vaccine series differed substantially between English- and Spanish-speaking parents. To maximize uptake of HPV vaccine, varying approaches might be needed to effectively target specific populations.

Abstract
Cervical cancer is a preventable public health problem. The two new human papillomavirus (HPV) vaccines are available but not accessible to everyone in South Africa, as they are very expensive. This study aimed to investigate educated peoples acceptability regarding HPV vaccination. This was a cross-sectional survey conducted among 146 master of business administration students by self-administered, anonymous questionnaire. The majority (74%) of the participants ever heard of cervical cancer, but only 26.2% heard about HPV. After reading the fact information regarding cervical cancer and HPV, the intention to vaccinate their daughters increased from 88% to 97.2% (P = 0.003). The majority (75.4%) indicated that HPV vaccination should be given before their daughters are mature enough to understand about sex, and 80.3% reported that they will discuss matters related to sex with their daughters if their daughters want to know about the vaccine. Those who did not want to vaccinate their daughters highlighted that they want more information regarding safety of the vaccine which might change their decision towards HPV vaccination. A health education information method can increase the vaccination acceptance rate in South Africa.

Abstract
Purpose To explore female college students’ perceived benefits and barriers to cervical cancer screening and perceived vulnerability to cervical cancer. Method The study was exploratory and cross sectional. The Pap Smear Belief Questionnaire was distributed online to a sample of 267 female undergraduate baccalaureate nursing students. Findings Students who obtained routine Pap smears perceived greater benefits and fewer barriers to routine screening than the students who did not obtain routine Pap smears. Personal vulnerability to cervical cancer was not a significant finding. Students who were in a long-term relationship, non-smoking and initiated sexual intercourse at a younger age were more likely to obtain routine screening. Conclusion Stressing importance of preventive health care associated with routine cervical cancer screening is important to promote women’s health regardless of age or level of education. Further studies with a broader range of college students as participants are needed to better understand their beliefs about the benefits and barriers to obtaining routine screening, and their perceptions of vulnerability to cervical cancer.

Abstract
BACKGROUND The objectives of this present study were to assess the awareness of cervical cancer and its risk factors among female undergraduates in South Africa, and to determine the their level of acceptability of Human Papillomavirus (HPV) vaccination. MATERIALS AND METHODS This cross-sectional study was conducted in March 2013 among 440 full time undergraduate female students. RESULTS Of those students who never had sex (n=163), 96 (58.9%) had ever heard of cervical cancer and only 12 students (12.5%) knew that HPV causes cervical cancer. More than a third (35.4%) of the students correctly said that sexual intercourse before age of 18 years is a risk factor for cervical cancer and 55.2% of the students knew about the Pap smear test which is used for screening cervical cancer. The majority (77.3%) were willing to accept HPV vaccination. Results revealed that students who knew about the Pap smear test, and were aware that having multiple sex partners, sexual intercourse before the age of 18 years, smoking and having contracted any STDs are risk factors for cervical cancer were more likely to accept HPV vaccination compared to other groups. CONCLUSIONS The general knowledge of South African female university students about cervical cancer is not sufficient but they have positive attitudes toward getting vaccinated with the HPV vaccine.

Abstract
The prevalence of HIV and HPV is high among men who have sex with men (MSM) in China. It is unclear whether cognitive and affective responses related to HPV and HPV-related diseases are negatively associated with HIV-related risk behaviors among MSM. This cross-sectional study interviewed 449 adult Chinese MSM in Hong Kong. The prevalence of unprotected anal intercourse (UAI) and having had anal sex with more than one man in the last 6 months (multiple male sex partnerships) was 39.0 and 71.3 %, respectively. After adjusting for four significant background variables (education level, cohabitation with a man, exposure to HIV prevention materials, and HIV voluntary counseling and testing), variables negatively associated with UAI and/or multiple male sex partnerships included (1) correct HPV-related knowledge (AOR = 0.48-0.66), (2) perceived susceptibility (AOR = 0.32-0.55) and perceived severity (AOR = 0.12-0.60) related to HPV and HPV-related diseases, and (3) fear towards contracting genital warts and penile/anal cancer (AOR = 0.40-0.55). Perceived high chance of contracting HPV was positively associated with multiple partnerships (AOR = 4.74). It is possible to reduce HIV-related risk behaviors by increasing levels of knowledge, cognitions, and fear related to HPV and related diseases. It is important to integrate prevention of HIV with prevention of sexually transmitted infections. Such interventions are warranted.

Abstract
OBJECTIVES Human papillomavirus (HPV) vaccines have been approved since 2006, yet vaccination rates remain low. We investigated HPV vaccination trends, interest, and reasons for nonvaccination in young adult women. METHODS We used data from the 2008-2012 National Health Interview Survey to analyze HPV vaccine uptake trends (≥ 1 dose) in women aged 18 to 26 years. We used data from the 2008 and 2010 National Health Interview Survey to examine HPV vaccination interest and reasons for nonvaccination among unvaccinated women. RESULTS We saw significant increases in HPV vaccination for all young women from 2008 to 2012 (11.6% to 34.1%); however, Hispanics and women with limited access to care continued to have lower vaccination rates. Logistic regression demonstrated lower vaccination interest among unvaccinated women in 2010 than 2008. Respondents in 2010 were significantly less likely to give lack of knowledge as a primary reason for nonvaccination. CONCLUSIONS Uptake of HPV vaccine has increased from 2008 to 2012 in young women. Yet vaccination rates remain low, especially among women with limited access to care. However, unvaccinated women with limited health care access were more likely to be interested in receiving the vaccine.

Abstract
IMPORTANCE Since licensure of the human papillomavirus (HPV) vaccine in 2006, HPV vaccine coverage among US adolescents has increased but remains low compared with other recommended vaccines. OBJECTIVE To systematically review the literature on barriers to HPV vaccination among US adolescents to inform future efforts to increase HPV vaccine coverage. EVIDENCE REVIEW We searched PubMed and previous review articles to identify original research articles describing barriers to HPV vaccine initiation and completion among US adolescents. Only articles reporting data collected in 2009 or later were included. Findings from 55 relevant articles were summarized by target populations: health care professionals, parents, underserved and disadvantaged populations, and males. FINDINGS Health care professionals cited financial concerns and parental attitudes and concerns as barriers to providing the HPV vaccine to patients. Parents often reported needing more information before vaccinating their children. Concerns about the vaccine's effect on sexual behavior, low perceived risk of HPV infection, social influences, irregular preventive care, and vaccine cost were also identified as potential barriers among parents. Some parents of sons reported not vaccinating their sons because of the perceived lack of direct benefit. Parents consistently cited health care professional recommendations as one of the most important factors in their decision to vaccinate their children. CONCLUSIONS AND RELEVANCE Continued efforts are needed to ensure that health care professionals and parents understand the importance of vaccinating adolescents before they become sexually active. Health care professionals may benefit from guidance on communicating HPV recommendations to patients and parents. Further efforts are also needed to reduce missed opportunities for HPV vaccination when adolescents interface with the health care system. Efforts to increase uptake should take into account the specific needs of subgroups within the population. Efforts that address system-level barriers to vaccination may help to increase overall HPV vaccine uptake.

Vaccine 2010; 29:153-60. [PMID: 21055494 DOI: 10.1016/j.vaccine.2010.10.068] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2010] [Revised: 10/10/2010] [Accepted: 10/24/2010] [Indexed: 11/29/2022]
Abstract
Knowledge about HPV and cervical cancer (CC) depends on several factors such as gender and education, which brings implications for health strategies and vaccination. A survey was conducted in Portugal with a representative sample of 1706 university students. Only 55.4% (n=945) had already heard of HPV, although 88.3% (n=834) from that know that is a risk factor for CC. 89% students (n=841) wants to be vaccinated against it, but only 13.8% stated as main reason to be vaccinated "prevention of the disease". Mean scores of knowledge were calculated. Statistical differences were found, regarding "CC knowledge", in gender (p<0.001) and between health sciences schools and non-health sciences schools (p<0.001). Differences regarding the study area in "knowledge and beliefs of HPV" (p<0.001) and in "relation between HPV and CC" (p<0.001) were found. Therefore, these differences may help to develop effective strategies that lead to decline CC incidence and mortality.
