P-34. Patients’ Survey of Human Papilloma Virus Vaccination among Systemic Lupus Erythematosus Patients in Japan after Suspension of Proactive Recommendation

Abstract Background Systemic lupus erythematosus (SLE) patients are known to have a high incidence of cervical cancer. The main reason for this is considered to reflect the high rate of Human papilloma virus (HPV) infection and inadequate HPV clearance due to immunosuppressive status. Japan has been facing a problem of low HPV vaccination rates due to the suspension of proactive recommendations for routine HPV vaccination for more than eight years because of the negative media campaign. The objective of this study is to identify the factors that inhibit HPV vaccination among SLE patients to develop strategies for improving HPV vaccination rate. Figure Sources of medical information for HPV vaccinated and unvaccinated participants. We asked which informational tools participants use to gather medical information. The most trusted sources are indicated by dark bars; others are indicated by light bars. * indicates significant differences between HPV vaccinated and unvaccinated participants (p<0.05, chi-square test). (a): Answers by HPV vaccinated participants. (b): Answers by HPV unvaccinated participants. HPV, Human papilloma virus; SNS, Social networking service; TV, Television Methods We conducted a questionnaire survey of female SLE patients aged 18-45 years attending our hospital to analyze factors related to HPV vaccination. Results We obtained responses of 83 participants. Only 5 (6.0%) were received HPV vaccination, 15 (18.1%) were uncertain of their vaccine history, and 27 (32.5%) had never even heard of HPV vaccination. The reasons for unvaccinated against HPV were "don't know" with 24 participants, "missed opportunity" with 15, and "troublesome, somehow" with 8. The most trusted source of medical information for the unvaccinated was their physician (47, 60.3%) (Figure). Among the unvaccinated, those who wished to be vaccinated in the future were positively correlated with “trust of vaccine benefit” (r=0.515. p=0.014) and “accurate knowledge about HPV vaccine” (r=0.614, p=0.002), and negatively correlated with “negative attitudes toward vaccination and vaccine policy” (r=-0.562, p=0.007). Conclusion HPV vaccination rate among SLE patients in Japan was extremely low. The main reason was lack of knowledge. The most effective solution is considered to provide accurate information and adequate recommendations of HPV vaccination by attending physicians.

Effect of information awareness on attitudes toward human papillomavirus vaccination intentions in Japan.

The Human Papillomavirus (HPV) vaccination rate among Japanese high school girls remains critically low, reflecting ongoing public apprehension and misinformation. This study explores the relationship between information presentation and attitudes toward HPV vaccination in Japan. We conducted a web-based survey of female high school students aged 15 to 16 and mothers of daughters of similar age across Japan. The first screening questionnaire investigated the vaccine uptake among eligible students. The detailed questions assessing awareness of HPV vaccination information, including vaccine eligibility and its cost, effectiveness, lifetime prevalence of HPV infection, and vaccine safety, were asked to the respondents. After presenting each piece of information, we investigated how the information influenced the vaccination attitudes of unvaccinated students and mothers of unvaccinated girls. Data collection occurred from August 20 to August 24, 2021. Of 473 students, 68 (14.4%) had already been vaccinated before the study. Over half of the 245 participating students were aware of vaccine eligibility and cost (68.7%) and effectiveness (63.6%), but fewer understood lifetime prevalence (28.7%) and safety (45.3%). In contrast, awareness of the same questions in 245 mothers was higher than that in the students: 90.2%, 92.5%, 55.4%, and 61.1%, respectively. Among unvaccinated students and mothers of unvaccinated girls, the intention to get vaccinated increased the most after being informed about the lifetime risks of HPV infection; 50.5% of students and 38.8% of mothers showed a positive attitude toward the HPV vaccination. Bridging the awareness gap between students and mothers is crucial for improving HPV vaccination rates. The findings underscore the potential of specific, targeted information to influence vaccination intentions, particularly regarding the HPV infection rate.

Updates in Human Papillomavirus Vaccination to Improve Medical Readiness in Active Duty Service Members.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States and is associated with the development of genital warts, precancerous lesions, and cancers of the oropharynx, anus, penis, vulva, vagina, and cervix. HPV-associated diseases are preventable through vaccination. An Australian nationwide vaccination program will effectively eliminate cervical cancer as a public health concern by the year 2035. Despite safety and efficacy data, vaccination against HPV is not mandatory for military service members. Active duty service women are more likely to test positive for HPV when compared to dependents, and veterans diagnosed with HPV-associated cancers have higher health care resource utilization and costs. Even if a patient has a prior HPV infection, vaccination at the time of HPV diagnosis or following treatment can reduce recurrence of HPV and dysplasia. In addition, patients with a history of cancer have a higher incidence of secondary HPV-associated malignancies and should be offered vaccination or re-vaccination if they received a hematopoietic stem-cell transplant. Improving HPV vaccination rates within the military health system requires a multidisciplinary approach. Providers should use every opportunity to recommend HPV vaccination, including recommending HPV vaccines for individuals who do not have a record of HPV vaccination. The electronic health record can be utilized to generate prompts for vaccine reminders, and clinics should stock HPV vaccines to allow for easy administration. Additionally, adoption of an opt-out policy for HPV vaccines rather than mandatory vaccination may be an acceptable alternative to increase HPV vaccination while allowing active duty service members to retain autonomy.

Parental Perspectives on Human Papillomavirus (HPV) Vaccination in Gulf Cooperation Council Countries: A systematic review.

This systematic review aims to synthesize existing research on parental knowledge, attitudes, and barriers to human papillomavirus (HPV) vaccination in the Gulf Cooperation Council (GCC) countries. Following PRISMA guidelines, this systematic review analyzed parental knowledge, attitudes, and barriers to HPV vaccination in 6 GCC countries. A comprehensive search across multiple electronic databases (Embase, Cumulative Index of Nursing and Allied Health Literature, Scopus, Ovid MEDLINE, Web of Science, and PubMed) was conducted, focusing on studies published between January 2010 and December 2023. Inclusion criteria targeted studies in English or Arabic involving parents in GCC countries, excluding non-research publications and those not using survey techniques. The review included 7 studies from Saudi Arabia, the United Arab Emirates, and Qatar. No study was found in Oman, Bahrain, and Kuwait. The findings highlighted low knowledge and awareness of HPV and the vaccine, with significant variation across studies. According to our review findings, the level of awareness in the 7 studies was found to be low to high. These studies collectively illustrate a range of awareness levels, from as low as 11% awareness of the HPV-cervical cancer link to as high as 68% general awareness of HPV. Attitudes towards vaccination were poor in Saudi Arabia but more positive in the United Arab Emirates and Qatar. Major barriers included safety concerns, lack of information, and cultural beliefs. Despite moderate awareness in some GCC countries, substantial knowledge gaps and vaccine hesitancy persist. Targeted educational campaigns, effective communication strategies, and involvement of community leaders are essential to improve HPV vaccination uptake.

Human PapillomaVirus Vaccine Uptake: Attitudes and Practices Among Moroccan Physicians.

In Morocco, cervical cancer is a serious public health problem with an estimated number of 2165 new cases and 1199 deaths in 2020. The human papillomavirus (HPV) vaccine has been available in Morocco since 2008. Few data are available on physicians' practices and attitudes toward HPV vaccine. Hence, this study aims to evaluate physicians' awareness and practice towards HPV vaccine and to highlight the main factors affecting physicians' recommendation of this vaccine in Morocco. We have carried out a structured interviewer-administered questionnaire with 500 physicians in different Moroccan regions between March 2019 and March 2020. This study showed an insufficient level of awareness of the two most common types of HPV associated with cervical cancer (36.6%). The rate of HPV vaccine recommendation did not exceed 16.6%. However, more than 63% of participants who were aware of HPV vaccine were willing to recommend it for their future eligible patients. Age (p value < 0.01), sector of activity (p value < 0.01), awareness of the two most common types of HPV associated with genital warts (p value = 0.02), of the vaccine schedules (p value = 0.03), and of the commercial name of this vaccine (p value < 0.01), were significant factors influencing physicians' recommendation of HPV vaccine. Our results showed that, older age (above 51years old) was associated with negative attitude towards the recommendation of this vaccine (OR: 0.17, 0.06-0.46 CI 95%). Practice in public sector was positively associated with recommendation of HPV vaccine (OR: 7.54, 3.38-16.80 CI 95%). Who were aware of the two most common types of HPV associated with genital warts were more likely to recommend HPV vaccine (OR: 3.36, 1.31-8.65 CI 95%). In the same line, participants, who were also more likely to recommend the vaccine, were those who were aware of HPV vaccine schedules (OR: 6.07, 3.51-10.50 IC 95%); participants who were aware of the commercial name of the HPV vaccine were more likely to recommend the vaccine (OR: 10.04, 5.02-20.09 IC 95%). Indeed, raising physicians' awareness is urgently needed to improve HPV vaccine coverage within Moroccan population.

Human Papillomavirus (HPV) Vaccination Rates Among U.S. Military Veteran Females and Males and Non-Veterans in the National Health Interview Survey.

Human papillomavirus (HPV) infection is a major risk factor for the development of multiple cancers. Active duty service members have higher rates of HPV infection than civilians, while Veterans are diagnosed with a disproportionately high burden of HPV-associated cancers compared to civilians without prior service. While a highly effective HPV vaccine has been available for over a decade, vaccination rates in the United States remain suboptimal. The objective of this study was to investigate HPV vaccination rates among male and female Veterans compared with their non-Veteran counterparts. We performed a secondary analysis of cross-sectional National Health Interview Survey (NHIS) data pooled from 2015 to 2018 to analyze HPV vaccination rates for respondents aged 18-45 years. We used multivariable logistic regression to compare HPV vaccination rates between Veterans and non-Veterans stratified by sex while controlling for sociodemographic factors, including age, race/ethnicity, education level, income, insurance coverage, and VA coverage. All analyses used NHIS survey weights to produce national estimates. Among 45,493 respondents aged 18 to 45 years, vaccination rates were low across all groups: 9.6% of male Veterans and 8.4% of male non-Veterans (P = .21) had received at least one HPV immunization, whereas 32.0% of female Veterans and 25.1% of female non-Veterans (P = .02) were immunized. After controlling for sociodemographics, both male Veterans (AOR 1.79; 95%CI 1.31, 2.44) and female Veterans (AOR 1.56; 95%CI 1.1, 2.21) exhibited higher odds of HPV vaccination compared to their non-Veteran counterparts. VA coverage was also independently associated with higher odds of HPV vaccination among female Veterans (AOR 2.39; 95%CI 1.10, 5.21). Veterans of both sexes are more likely to be vaccinated than their non-Veteran civilian counterparts. However, vaccination rates overall remain low. To our knowledge, ours is the first study of its kind to establish HPV vaccination rates among female Veterans. These findings underscore the important role of DoD and VA health care systems in improving HPV vaccine uptake and mitigating HPV-associated cancer risk among Veterans.

Key informant perspectives on overcoming HPV vaccination barriers in low-immunization NY counties

ABSTRACT Human papillomavirus (HPV) infection is an important public health concern, with nearly 2,900 cases of HPV-related cancers reported in New York State (NYS) each year. Despite concerted efforts to enhance vaccine uptake in NYS, HPV vaccination rates among 13–15-year-olds failed to meet the 2020 healthy People target, and continue to lag behind the 2030 goal, of 80%. In counties with low immunization levels, understanding factors influencing decision-making among unvaccinated adolescents is crucial. This study aimed to identify barriers, facilitators, and potential interventions to improve HPV vaccine uptake. Qualitative semi-structured interviews were conducted with key informants in 15 NYS counties within the lowest quartile of HPV vaccine coverage among 13-year-old adolescents. Public health representatives, including Immunization Quality Improvement for Providers (IQIP) consultants, vaccine coordinators, medical directors, and primary care providers, were identified through purposive and snowball sampling. Interviews explored vaccination coverage knowledge, barriers and facilitating factors, and recommended strategies for improvement. All conversations were audio-recorded, transcribed, and analyzed using ATLAS.ti. Forty-four interviews were conducted, revealing barriers to HPV vaccination such as limited vaccine knowledge, vaccine misinformation, and accessibility. Key informants asserted barriers could be primarily addressed through education efforts, such increased public awareness, improved parent–doctor conversations, additional provider education on vaccine benefits, and supplementary education in patient spaces. Targeted education efforts and improved provider communication strategies have the potential to bolster HPV vaccination rates in NYS. These findings offer valuable insights for guiding future initiatives in communities facing significant barriers to vaccination.

Accountable care organizations and HPV vaccine uptake: a multilevel analysis.

To examine associations between accountable care organization (ACO) membership and human papillomavirus (HPV) vaccination and to evaluate variation in HPV vaccination across ACO providers. Retrospective cohort study. We analyzed the records of commercially insured children and adolescents aged 11 to 14 years using Connecticut's All-Payer Claims Database from January 2012 to December 2017. A total of 23,911 adolescents receiving care from 933 ACO-attributable providers and 923 non-ACO-attributable providers were included. The mean rate of HPV vaccine initiation was 53% overall (51% among boys, 55% among girls). Among those who initiated the vaccine, the mean rate of HPV vaccine completion was 69% (67% among boys, 70% among girls). Adolescents receiving care at ACOs vs non-ACOs were significantly more likely to receive initial HPV vaccination (OR, 1.80; 95% CI, 1.69-1.91) and to complete the HPV vaccine series (OR, 1.12; 95% CI, 1.01-1.23). Among adolescents receiving care in ACOs, providers were responsible for 14% of variability in HPV vaccine initiation and 10% of variability in HPV vaccine completion and ACOs were responsible for less than 1% of variability in HPV vaccine initiation and completion. Adolescents receiving care from ACOs were significantly more likely to initiate and complete HPV vaccination than were adolescents receiving care in non-ACO settings. Variation in HPV vaccine uptake attributable to providers within ACOs dwarfed variation attributable to ACOs, indicating that vaccine uptake was more dependent on the provider irrespective of the ACO with which they were affiliated. Efforts to improve HPV vaccination rates may require provider-focused interventions regardless of the overall performance of their health care system orproviderorganization.

Optimizing Protection Against HPV-Related Cancer: Unveiling the Benefits and Overcoming Challenges of HPV Vaccination.

Human papillomavirus (HPV) vaccine is an underutilized tool in cancer prevention. HPV vaccine completion rates in adolescents age 13 to 15 years remain low at 59%. The HPV vaccine can prevent more than 90% of cases of cancer caused by HPV, including cervical, oropharyngeal, anal, penile, vulvar, and vaginal. HPV vaccine is very safe and effective, as demonstrated by numerous large-scale studies. Practice-based strategies can improve vaccination rates, such as having providers give a strong presumptive recommendation for the vaccine, using motivational interviewing for hesitant families, and using electronic health record reminders to prompt providers to offer it, among other interventions. Offering HPV vaccine starting at age 9 years is another evidence-based strategy to improve HPV vaccine completion rates, which has been shown to be acceptable to both providers and parents.

Abstract A146: Racial/ethnic differences in the relationship between human papillomavirus vaccination status and up-to-date Papanicolaou tests

Abstract Background: Human papillomavirus (HPV) vaccination and routine Papanicolaou (Pap) testing can prevent morbidity and mortality associated with cervical cancer (CC). Research suggests women who have initiated and completed the HPV vaccine are more likely to have an up-to-date Pap test than women who are unvaccinated against HPV. Limited research has focused on whether the association between HPV vaccination and Pap testing varies based on the number of HPV vaccine doses received across racial/ethnic groups. Methods: We conducted a cross-sectional analysis of 2018 – 2022 Behavioral Risk Factor Surveillance System data to investigate the relationship between HPV vaccination status and having an up-to-date Pap test by race/ethnicity. Based on the Advisory Committee on Immunization Practices’ (ACIP) guidelines, women who received 0 doses of the HPV vaccine were unvaccinated, women who received 1 or 2 doses initiated the vaccine series, and women who received 3 doses completed the HPV vaccine series. Based on the United States Preventive Services Task Force guidelines, women were considered to have an up-to-date Pap test if they reported having one within the past 3 years. We used weighted multivariable logistic regression models to examine the association. Results: Most women (n = 14,615) were unvaccinated (82.9%) and had an up-to- date Pap test (75.5%). Non-Hispanic White (NHW) women had the highest rate of HPV vaccine series completion (11.8%), followed by non-Hispanic Other (NHO) women (11.2%), non- Hispanic Black (NHB) women (8.6%), and Hispanic women (8.3%). NHW women also had the highest rate of up-to-date Pap test (78.8%). NHB women had the second highest rate (77.6%), followed by Hispanic women (67.8%), and NHO women (66.4%). In adjusted analyses, NHO women were 34% less likely to have an up-to-date Pap test than NHW women (OR, 0.66; 95% CI: 0.51-0.86). Compared to unvaccinated women, those who completed and initiated the HPV vaccine series were more likely to have an up-to-date Pap test (initiated: OR: 1.40, 95% CI: 1.04-1.87; completed: OR:1.77, 95% CI: 1.35-2.34). NHB and NHO women who initiated the HPV vaccine series were more likely to have an up-to-date Pap test (NHB: OR: 3.37, 95% CI: 1.65-6.85; NHO: OR: 3.21, 95% CI: 1.73-5.95). NHW women who completed the HPV vaccine series were more likely to have an up-to-date Pap test (OR: 2.19, 95% CI: 1.55-3.08). Conclusion: NHB and NHO women who initiated the HPV vaccine series were three times as likely to have an up-to-date Pap test; NHW women who have completed the HPV vaccine series were twice as likely to receive an up-to-date Pap test. Women who do not receive Pap tests or the HPV vaccine miss important CC prevention opportunities. Thus, relevant stakeholders should aim to improve HPV vaccination rates; doing so could potentially enhance Pap test adherence simultaneously. This may be especially important for NHB and NHO women as they have lower rates of Pap test adherence and HPV vaccine series completion.

Our Daughters-Ourselves: Evaluating the Impact of Paired Cervical Cancer Screening of Mothers with HPV Vaccination for Daughters to Improve HPV Vaccine Coverage in Bamako, Mali.

Cervical cancer (CC) is the second most common cancer in Western Africa, accounting for 12,000 cases and 6000 deaths annually. While vaccination against human papilloma virus (HPV) and CC screenings reduce the incidence and mortality of CC in many developed countries, 90% of CC deaths are in low-income countries. Lack of knowledge about the connection between HPV and CC, lack of access to vaccines and screenings, weak healthcare infrastructure, and stigma related to sexually transmitted diseases are among the factors that contribute to this disparity. Previously, we evaluated the knowledge of HPV and CC in Bamako, Mali, showing that knowledge of the link between HPV and CC was very low (less than 8% of participants) and that less than 3% of women were screened for CC. Subsequent implementation of a community-based education program and support for local clinics resulted in a five-fold increase in CC screening at the five participating clinics in 2015. In this study, we paired CC screenings of mothers with HPV vaccination of their daughters to target out-of-school (OOS) girls whom school-based vaccination campaigns would not reach. Our campaign resulted in a 10.7% increase in HPV vaccination.

Assessing Saudi women’s awareness about human papillomavirus (HPV) and their susceptibility to receive the vaccine

ABSTRACT Cervical cancer is a significant health concern for women worldwide, with human papillomavirus (HPV) being the primary cause. This study aimed to assess Saudi women’s awareness and knowledge of HPV, determine their information sources, and evaluate their intention to receive the HPV vaccine. A questionnaire-based survey was conducted among 654 Saudi females aged 18 to 60 years from January to May 2023. The results revealed that 60.85% of the participants had heard about HPV, but only 8.25% had received the HPV vaccination. Despite the low vaccination rate, 71.11% of the respondents expressed willingness to receive the vaccine. Educational level was the significant predictor of the vaccine awareness and acceptance. The internet and social media were the most prevalent sources of information about HPV. The study highlights the need for additional education about HPV-related diseases and vaccination among Saudi women. Although there is a high level of HPV vaccine acceptance, the lack of knowledge suggests that targeted educational interventions are necessary to increase awareness and promote vaccination uptake. These findings can inform public health strategies to reduce the burden of cervical cancer in Saudi Arabia through improved HPV vaccination coverage and education.

Effect of health education on the awareness of human papillomavirus infection among undergraduate students of a health sciences university – An interventional study

BACKGROUND: Human papillomavirus (HPV) infection is a significant public health concern associated with various cancers. Despite available vaccines, knowledge gaps persist among healthcare students, impacting vaccine uptake. This study aimed to assess the impact of an educational intervention on health-care students’ knowledge, attitudes, and practices regarding HPV infection and vaccination. Furthermore, the study aimed to assess the potential barriers to vaccination. METHODOLOGY: A pre- post-interventional study was conducted among 656 undergraduate healthcare students over a period of 1 year to assess baseline knowledge, attitudes, and practices related to HPV infection and vaccination using a self-structured validated questionnaire. Following this, an educational intervention, in the form of an interactive PowerPoint presentation, was conducted. Moreover, posttest surveys were administered 1 month after the intervention. Statistical analyses were performed using IBM SPSS v23.0. RESULTS: The median age of the students in the study was 21 years. Pretest surveys revealed knowledge gaps and misconceptions among participants with a knowledge score of 10.59 ± 6.58 (mean ± standard deviation [SD]), attitude score of 1.31 ± 1.944 (mean ± SD) and pretest willingness to receive the vaccine was 6.4%. Whereas, postintervention, significant improvements were observed in knowledge, attitudes, and practices regarding HPV infection and vaccination, with a mean knowledge score of 25.82 ± 8.34 and a mean attitude score of 3.84 ± 4.259. Practices also improved, with more participants expressing readiness to receive (75.9%) and advocate for vaccination. Moreover, the study demonstrated the potential barriers to vaccination as lack of awareness, nonavailability, and cost of the vaccine. CONCLUSION: Targeted educational interventions effectively improved HPV vaccination awareness and acceptance among health-care students. These findings contribute to public health efforts in HPV prevention and control.

Knowledge about human papillomaviruses among students in Germany-a cross-sectional study with aneed for action

The human papillomavirus (HPV) is one of the most common viruses transmitted through intimate contact, causing many benign and malignant diseases. Vaccination protects against these diseases. Despite the HPV vaccination being recommended by the Standing Committee on Vaccination (STIKO), knowledge and vaccination rates in Germany are very low. Therefore, the aim of the study was to assess the HPV knowledge among German students. Between 06/2019 and 01/2024, anationwide online survey on HPV knowledge among students in Germany was distributed via the respective student councils. The survey included two aspects: 1)basic characteristics of the participants and 2)knowledge questions about HPV (e.g., transmission routes, effectiveness, and side effects of vaccination, knowledge about the HPV subtypes). Data collection was anonymous. Atotal of 459 students took part in the study. Of these, 335 (72.98%) were female, 122 (26.57%) were male, and2 (0.45%) did not specify their gender. The average age of the students was 24.02 years, and most of the participants were in their 6th (23.31%/107) semester. In all, 75.82% (348) of the participants were medical students followed by law students with 19.61% (90) participants. The most represented study location was Aachen, with 270 (58.82%) participants. Only about half (48.80%/223) of the students knew that approximately 8000 new cancer cases in Germany are HPV-associated annually. Regarding the HPV vaccination, more than athird (35.82%/163) of participants did not know that it also protects against genital warts, while 21.93% (100) did not know that boys can also benefit from the HPV vaccination and that it does not only improve HPV protection of girls against cervical cancer. Despite several years of HPV vaccination recommendation by the Standing Committee on Vaccination (STIKO), knowledge about HPV among college students still remains very low. Further prevention and educational efforts are needed to address HPV knowledge gaps, with the additional goal of improving HPV vaccination rates.

Understanding the barriers and facilitators of human papillomavirus vaccine uptake in Kwale and Mombasa counties in Kenya: A study protocol

Background Cervical cancer poses a significant public health problem globally. Human papillomavirus (HPV) vaccination protects against HPV types 16 and 18, responsible for approximately 70% of cervical cancer cases. The optimal vaccination age is in the early adolescent period before sexual debut with possible HPV infection. In 2019, through the Ministry of Health, the Kenya government introduced the HPV vaccine to 10-14-year-old girls. However, analysis of the vaccine coverage across the counties shows that uptake is suboptimal. Our study proposes to apply the World Health Organization (WHO) Measuring Behavioural and Social Drivers (BeSD) of the vaccination framework to understand the barriers and facilitators of HPV vaccine uptake in two counties of Kenya. Methods The study design will be cross-sectional, utilising a mixed methods approach for data collection. We will sample 668 girls aged 10–14 years, across the two counties of Kwale and Mombasa and collect data using using an interviewer-administered questionnaire. Qualitative data will be collected through focus group discussions with CHEWs, and community leaders, and key informant interviews with nurses, clinical officers, vaccine program managers and national vaccine focal persons. We will use the WHO BeSDvaccination framework as our conceptual framework. Significance Understanding the barriers and facilitators for HPV vaccination will help in developing strategies to be applied for improving HPV vaccine uptake.

Development of Promising Interventions to Improve Human Papillomavirus Vaccination in a School-Based Program in Quebec, Canada: Results From a Formative Evaluation Using a Mixed Methods Design.

Despite the availability of school-based human papillomavirus (HPV) vaccination programs, disparities in vaccine coverage persist. Barriers to HPV vaccine acceptance and uptake include parental attitudes, knowledge, beliefs, and system-level barriers. A total of 3 interventions were developed to address these barriers: an in-person presentation by school nurses, an email reminder with a web-based information and decision aid tool, and a telephone reminder using motivational interviewing (MI) techniques. Here we report on the development and formative evaluation of interventions to improve HPV vaccine acceptance and uptake among grade 4 students' parents in Quebec, Canada. In the summer of 2019, we conducted a formative evaluation of the interventions to assess the interventions' relevance, content, and format and to identify any unmet needs. We conducted 3 focus group discussions with parents of grade 3 students and nurses. Interviews were recorded, transcribed, and analyzed for thematic content using NVivo software (Lumivero). Nurses received training on MI techniques and we evaluated the effect on nurses' knowledge and skills using a pre-post questionnaire. Descriptive quantitative analyses were carried out on data from questionnaires relating to the training. Comparisons were made using the proportions of the results. Finally, we developed a patient decision aid using an iterative, user-centered design process. The iterative refinement process involved feedback from parents, nurses, and experts to ensure the tool's relevance and effectiveness. The evaluation protocol and data collection tools were approved by the CHU (Centre Hospitalier Universitaire) de Québec Research Ethics Committee (MP-20-2019-4655, May 16, 2019). The data collection was conducted from April 2019 to March 2021. Following feedback (n=28) from the 3 focus group discussions in June 2019, several changes were made to the in-person presentation intervention. Experts (n=27) and school nurses (n=29) recruited for the project appreciated the visual and simplified information on vaccination in it. The results of the MI training for school nurses conducted in August 2019 demonstrated an increase in the skills and knowledge of nurses (n=29). School nurses who took the web-based course (n=24) filled out a pretest and posttest questionnaire to evaluate their learning. The rating increased by 19% between the pretest and posttest questionnaires. Several changes were made between the first draft of the web-based decision-aid tool and the final version during the summer of 2019 after an expert consultation of experts (n=3), focus group participants (n=28), and parents in the iterative process (n=5). More information about HPV and vaccines was added, and users could click if more detail is desired. We developed and pilot-tested 3 interventions using an iterative process. The interventions were perceived as potentially effective to increase parents' knowledge and positive attitudes toward HPV vaccination, and ultimately, vaccine acceptance. Future research will assess the effectiveness of these interventions on a larger scale.

A Systematic Review of Human Papillomavirus Vaccination Challenges and Strategies to Enhance Uptake.

Human papillomavirus (HPV) vaccination has revolutionized cervical cancer prevention. Clinical trials confirm that the quadrivalent (HPV types 6, 11, 16, 18) and bivalent (HPV types 16, 18) vaccines effectively prevent HPV infections and cervical neoplasia. The latest HPV vaccine protects against nine virus types responsible for 90% of cervical cancer cases globally. Despite their undoubted effectiveness in reducing morbidity and mortality associated with HPV infections, challenges in vaccine coverage and uptake persist. The current study aimed to identify the primary challenges associated with HPV vaccination, propose effective strategies to improve vaccination uptake, and compile relevant evidence into a comprehensive overview to inform policy and practice. A systematic review protocol, following PRISMA-P and PRISMA guidelines, was established. Articles were sourced from the Web of Science using keywords from a comprehensive review of HPV vaccination challenges and strategies. Studies published between 1 January 2020, and 1 May 2024, including RCTs and observational, qualitative, and cross-sectional studies, were included, while reviews, protocols, and commentaries were excluded. Titles, abstracts, and full texts were screened per PRISMA guidelines. The review identified five key strategies to improve HPV vaccination uptake: parental and school engagement, use of technology and multimedia tools, healthcare providers' role, multicomponent interventions, and targeted interventions for immigrant groups. This review emphasized the need for a multifaceted approach to improving vaccination rates, offering a robust foundation for policy and stakeholder initiatives.

Healthcare Professionals' Perspectives on HPV Recommendations: Themes of Interest to Different Population Groups and Strategies for Approaching Them.

As a flagship of the Europe's Beating Cancer Plan, the European Commission supports EU member states' efforts to strengthen and expand the routine vaccination of girls and boys against human papillomavirus (HPV). Populations across Europe have grown in diversity, and health systems must adapt to meet the specific needs of increasing diversity. Healthcare professionals (HCPs) must strive to communicate HPV vaccine information in a culturally sensitive manner and address specific concerns related to cultural beliefs, trust in health systems and perceived risks. The objectives of this exploratory study are to identify which themes are most frequently raised during the recommendation of vaccination to minors based on the characteristics of the population (religion, region of origin, gender, level of education and language proficiency) and to collect strategies to improve communication with a diverse population. A survey was distributed through various European public health institutions to HCPs in the region and their networks. The survey included multi-response questions (themes addressed during vaccination recommendation based on population characteristics) and open-ended questions (own qualitative comments and strategies). The most common issues that arise during vaccine recommendation are a lack of knowledge, followed by misinformation. Differences were detected according to the population characteristics. Suggested strategies to improve HPV vaccine recommendation focused on the following aspects: affordability; sexuality and gender; communication platforms; multilingualism; quality of care; school collaboration. HCPs report differences according to the characteristics of the population receiving the recommendation. Personalisation of the recommendations would help to optimise the decision-making process for some groups.

Identifying key challenges and optimizing approaches for training of health care professionals for HPV vaccination programmes

Healthcare professionals (HCPs) play a crucial role in building vaccine confidence and promoting vaccination programmes. HCP vaccination recommendations are often the strongest predictor of vaccine uptake, influencing individuals' acceptance of and demand for vaccination. However, HCP training on human papillomavirus (HPV) vaccination faces challenges in some countries, including Ethiopia, Malawi, and Uganda. This study summarizes the discussions held during the Coalition to Strengthen HPV Immunization Community Symposium in Africa, the field experiences of co-authors, and expert opinions to inform its findings. Key challenges faced in these countries are maintaining regular and comprehensive HCP training, ensuring continuity due to staff turnover, reaching all health facilities, and including teachers as key mobilizers. Funding constraints, limited communication materials, and human resource shortages can further impact training effectiveness. Recommendations for strengthening HCP training on HPV vaccination programmes include providing adequate training to all HCPs, refresher training, including private sector HCPs and teachers, leveraging local training institutions, and integrating HPV vaccine training into pre-service HCP academic curricula. These actions would be essential for improving HPV vaccine coverage and working towards cervical cancer elimination goals.

Improving HPV Vaccination Uptake Among Adolescents in Low Resource Settings: Sociocultural and Socioeconomic Barriers and Facilitators.

Lower- and middle-income countries (LMICs) are disproportionately impacted by human papillomavirus (HPV) and would benefit from implementing the HPV vaccine. In the context of competing health priorities, utilizing scarce domestic infrastructure and human resources for HPV vaccination remains challenging for many LMICs. Given the high benefits of the HPV vaccine, the World Health Organization (WHO) is now encouraging for all countries, particularly LMICs, to introduce HPV vaccines into their routine immunization programs. Understanding the barriers and facilitators to HPV adolescent vaccine programs in LMICs may help strengthen how LMICs implement HPV vaccine programs, in turn, increasing HPV vaccine acceptance, uptake, and coverage. To identify and assess barriers and facilitators to implementing adolescent HPV vaccination programs in LMICs. This study comprised a review of literature assessing adolescent HPV vaccination in LMICs published after 2020 from a sociocultural perspective. Overall, the findings showed that LMICs should prioritize increasing HPV vaccine availability and HPV vaccine knowledge, particularly focusing on cancer prevention, as knowledge reduces misinformation and increases vaccine acceptance. Evidence suggests that factors promoting HPV vaccine uptake include fostering low vaccine hesitancy, integrating HPV vaccination as a primary school routine vaccination, and vaccinating both genders. A one-dose HPV vaccine may enable many LMICs to increase vaccine acceptance, uptake, and coverage while controlling financial, infrastructure, and human resource costs. As HPV is one of the leading causes of death in many LMICs, implementing the HPV vaccine may be highly beneficial. Cohesive national HPV vaccine buy-in and understanding the success and challenges of prior LMIC HPV vaccine implementation is crucial to developing effective, efficient, and sustainable HPV vaccination programs.
