Abstract
This meta-analysis aimed to systematically review and analyze parental awareness of human papillomavirus (HPV) and its vaccine, as well as parental willingness of the HPV vaccine in China. The literature search selected studies that met the following criteria: study published between 2009 and 2023, study design involving parents with at least one child aged ≤ 18 years, sample sizes exceeding 300, availability of data on parental willingness of the HPV vaccine or sufficient information to calculate effect sizes, and studies published in either English or Chinese. Studies that did not meet one of the above points were excluded. From an initial pool of 660 papers, 33 studies were included, encompassing a total sample size of 92,802. The analysis revealed that the pooled awareness rates of HPV and the HPV vaccine among Chinese parents were 45.0% (95% CI: 36.1-54.0%) and 41.4% (95%CI: 30.7-52.5%), respectively. The overall parental willingness for vaccinating children against HPV was 61.0% (95% CI: 53.5-68.3%). Both parental awareness and willingness of the HPV vaccine in China were found to remain low when compared to other countries.

Abstract
Human papillomavirus (HPV) vaccines, primarily relying on neutralizing antibodies, have proven highly effective. Recently, HPV-specific antibodies have been detected in the female genital tract secretions captured by first-void urine (FVU), offering a minimally invasive diagnostic approach. In this study, we investigated whether HPV16-specific antibodies present in FVU samples retain their neutralizing capacity by using pseudovirion-based neutralization assays. Paired FVU and serum samples (vaccinated n = 25, unvaccinated n = 25, aged 18-25) were analyzed using two orthogonal pseudovirion-based neutralization assays, one using fluorescence microscopy and the other using luminescence-based spectrophotometry. Results were compared with HPV16-specific IgG concentrations and correlations between neutralizing antibodies in FVU and serum were explored. The study demonstrated the presence of neutralizing antibodies in FVU using both pseudovirion-based neutralization assays, with the luminescence-based assay showing higher sensitivity for FVU samples, while the fluorescence microscopy-based assay exhibited better specificity for serum and overall higher reproducibility. High Spearman correlation values were calculated between HPV16-IgG and HPV16-neutralizing antibodies for both protocols (rs: 0.54-0.94, p < .001). Significant Spearman correlations between FVU and serum concentrations were also established for all assays (rs: 0.44-0.91, p < .01). This study demonstrates the continued neutralizing ability of antibodies captured with FVU, supporting the hypothesis that HPV vaccination may reduce autoinoculation and transmission risk to the sexual partner. Although further protocol optimizations are warranted, these findings provide a foundation for future research and larger cohort studies that could have implications for the optimal design, evaluation, and implementation of HPV vaccination programs.

Abstract
Human papillomavirus (HPV) causes cervical as well as other cancers. Racial and ethnic disparities in cervical cancer incidence and mortality in the United States are well documented. HPV vaccination has been recommended in the United States since 2006 and is expected to prevent HPV-attributable cancers in all racial/ethnic groups. Quadrivalent HPV vaccine-type (HPV6/11/16/18) and nonvaccine-type cervicovaginal HPV prevalences were estimated from National Health and Nutrition Examination Surveys in 2015-2018 (vaccine era) and 2003-2006 (prevaccine era) data. Prevalence ratios comparing 2015-2018 to 2003-2006 were calculated among sexually experienced Non-Hispanic White (NHW), Non-Hispanic Black (NHB), and Mexican American (MA) females aged 14-24 years. Quadrivalent HPV vaccine-type prevalence declined 82% (CI: 60%-92%) among NHW, 86% (CI: 64%-95%) among NHB, and 100% among MA females, forecasting future reductions in cervical cancer across racial/ethnic groups.

Abstract
Despite the high effectiveness of HPV vaccines in preventing infection, vaccine hesitancy remains a concern, particularly in China. This study aimed to explore college students' attitudes toward HPV vaccination and identify associated factors. Data was collected through a cross-sectional survey using self-administered questionnaires in four cities from May to June 2022. Chi-square tests and logistic regression analyses were conducted to identify factors. Additionally, an integrated structural equation model (SEM) based on the 3Cs (confidence, convenience, complacency) was developed to understand underlying factors contributing to hesitancy. The results from 2261 valid questionnaires were enlightening. A significant 89.47% (59.4% for females) considered HPV vaccination necessary, with 9.82% remaining neutral and only 0.71% deeming it unnecessary. Factors like higher education, being a medical student, residing in urban areas, having medical insurance, more extraordinary living expenses, a family history of tumors, and a solid understanding of HPV played a role in perceiving the vaccine as necessary. Among the 1438 female respondents, 84.36% had no hesitancy toward HPV vaccination, 13.53% expressed hesitancy, and 2.11% refused vaccination. Factors like age, understanding of HPV, medical staff recommendations, living expenses, and family history influenced hesitancy levels. SEM revealed that the 3Cs significantly affected vaccine hesitancy. Factors like price, booking process, vaccination times, trust in vaccines, medical staff recommendations, efficiency, and risk perception collectively influenced hesitancy. In conclusion, this study found high acceptance of HPV vaccination but acknowledged the complexity of hesitancy factors. It recommends medical staff disseminate scientific knowledge, offer recommendations, simplify booking procedures, and expand vaccination sites to address vaccine hesitancy effectively.

Abstract
To assess the pattern of multiple human papillomavirus infection to predict the type replacement postvaccination. A total of 7372 women aged 18-45y from a phase III trial of an Escherichia coli-produced HPV-16/18 vaccine were analyzed at enrollment visit before vaccination. Hierarchical multilevel logistic regression was used to evaluate HPV vaccine type and nonvaccine-type interactions with age as a covariate. Binary logistic regression was construed to compare multiple infections with single infections to explore the impact of multiple-type infections on the risk of cervical disease. Multiple HPV infections were observed in 25.2% of HPV-positive women and multiple infections were higher than expected by chance. Statistically significant negative associations were observed between HPV16 and 52, HPV18 and HPV51/52/58, HPV31 and HPV39/51/52/53/54/58, HPV33 and HPV52/58, HPV58 and HPV52, HPV6 and HPV 39/51/52/53/54/56/58. Multiple HPV infections increased the risk of CIN2+ and HSIL+, with the ORs of 2.27(95%CI: 1.41, 3.64) and 2.26 (95%CI: 1.29, 3.95) for multiple oncogenic HPV infection separately. However, no significant evidence for the type-type interactions on risk of CIN2+ or HSIL+. There is possibility of type replacement between several pairs of vaccine and nonvaccine HPV type. Multiple HPV infection increased the risk of cervical disease, but coinfection HPV types seem to follow independent disease processes. Continued post-vaccination surveillance for HPV 51/52/58 types and HPV 39/51 types separately was essential after the first and second generation of HPV vaccination implementation in China.

Abstract
The uptake of human papillomavirus (HPV) vaccine remains suboptimal despite being a part of routine vaccination within national immunization program(s). This indicates probable challenges with the implementation of HPV immunization program(s) in various countries. The objective of this systematic literature review (SLR) was to identify implementation strategies for HPV vaccination within national and regional immunization programs worldwide with an aim to provide guidance for countries targeting to increase their HPV vaccine coverage rate (VCR). A comprehensive literature search was conducted across Medline and Embase and included articles published between January 2012 and January 2022. Of the 2,549 articles retrieved, 168 met inclusion criteria and were included in the review. Strategies shown to improve HPV vaccination uptake in the reviewed literature include campaigns to increase community awareness and knowledge of HPV, health care provider trainings, integrating HPV vaccination within school settings, coordinated efforts via multi-sectoral partnerships, and vaccination reminder and recall systems. Findings may help national authorities understand key considerations for HPV vaccination when designing and implementing programs aiming to increase HPV VCR in adolescents.

Abstract
Despite the availability of school-based immunization programs (SBIPs) in Canada, human papillomavirus (HPV) vaccine uptake remains suboptimal. Vaccine education may improve vaccine uptake among adolescents. The objective of this qualitative study was to identify opportunities for HPV vaccine education in British Columbia, Canada, by exploring the perspectives of students, parents, school staff, and public health nurses on the current SBIP. Individual semi-structured interviews were conducted with adult participants and focus groups were conducted with grade 6 students between November 2019 and May 2020. The interviews and focus groups were transcribed and then analyzed using reflexive thematic analysis. Opportunities for HPV vaccine education were identified in three themes: 1) making SBIPs student-centered; 2) adopting a collaborative and interdisciplinary approach to vaccine education; and 3) actualizing parent education opportunities. Broad support existed for a formal, collaborative HPV grade 6 vaccine curriculum delivered by teachers and public health nurses to provide evidence-based health information. Participants voiced that the curriculum should integrate students' perspectives on topics of interest and address needle associated pain and anxiety. Parents were identified as the primary vaccine decisionmakers, therefore, participants stated it was crucial to also provide parent-directed vaccine education as part of SBIP. Our findings support the development of a collaborative HPV vaccine curriculum directed to and informed by students and parents to buttress current SBIPs in British Columbia.

Abstract
The epidemiological and clinical aspects of Human Papillomavirus (HPV) infection in women have been extensively studied. However, there is a lack of information regarding HPV characteristics in males. In this study, we conducted a retrospective and observational study of 3737 consecutive male individuals attending outpatient clinics of Guangdong Women and Children Hospital from 2012 to 2023 in Guangzhou, South China, to determine the age- and genotype-specific prevalence of HPV in men. The results showed the overall prevalence of HPV among men was 42.15% (1575/3737), with variations ranging from 29.55% to 81.31% across distinct diagnostic populations. Low-risk HPV6 (15.47%), HPV11 (8.94%), and high-risk HPV52 (5.51%) were the most common types. The annual HPV prevalence decreased significantly (Z = -3.882, p < .001), ranging from 31.44% to 52.90%. 28.77% (1075/3737) of men manifested infection with a singular HPV type, predominantly identified as a low-risk type. The age-specific distribution of HPV infections revealed distinctive peaks in the < 25 y age group (47.60%, 208/437) and the 40-44 y age group (44.51%, 154/346). Notably, the positive rate of Chlamydia trachomatis was significantly higher among HPV-positive individuals in comparison to HPV-negatives (16.14% vs. 11.25%, p < .05). Our findings reveal a substantial prevalence of HPV infection among outpatient men in Guangzhou, South China. It is recommended to consider the inclusion of HPV vaccination for adolescent males in national immunization schedules, once an adequate supply of vaccines is accessible.

Abstract
In 2018, the Food and Drug Administration expanded the age of eligibility for the human papillomavirus (HPV) vaccine to 27 to 45 years. However, it is unclear if there are racial/ethnic disparities in HPV vaccine uptake for this age-group following this expanded recommendation. We aimed to identify any disparities in HPV vaccine in 27 to 45 year-olds based on sociodemographic factors. We analyzed nationally representative, cross-sectional data from the 2019 National Health Interview Survey (n = 9440). Logistic regression models estimated the odds of vaccine uptake (receipt of ≥1 vaccine dose) based on sociodemographic factors. Participants were mostly Non-Hispanic Whites (60.7%) and females (50.9%). In adjusted models, females had over three times greater odds of vaccine uptake compared to males (aOR = 3.58; 95% CI 3.03, 4.23). Also, compared to Non-Hispanic Whites, Non-Hispanic Blacks were 36% more likely (aOR = 1.36; 95% CI 1.09, 1.70), and Hispanics were 27% less likely (aOR = 0.73; 95% CI 0.58, 0.92) to receive the vaccine. Additionally, individuals without a usual place of care had lower odds of vaccine uptake (aOR = 0.72; 95% CI 0.57, 0.93), as were those with lower educational levels (aORhigh school = 0.62; 95% CI 0.50, 0.78; aORsome college = 0.83; 95% CI 0.70, 0.98). There are disparities in HPV vaccine uptake among 27 to 45 year-olds, and adult Hispanics have lower odds of receiving the vaccine. Given the vaccine's importance in cancer prevention, it is critical that these disparities are addressed and mitigated.

Abstract
Current estimates of the HPV infection rate in China vary by geographic region (9.6-23.6%), with two age peaks in prevalence in women ≤20-25 years of age and 50-60 years of age. HPV-16, 52 and 58 are the most commonly-detected HPV genotypes in the Chinese population. In China, five HPV vaccines are licensed and several others are undergoing clinical trials. Multiple RCTs have shown the efficacy and safety of the bvHPV (Cervarix), Escherichia coli-produced bvHPV (Cecolin), Pichia pastoris-produced bvHPV (Walrinvax), qvHPV (Gardasil) and 9vHPV (Gardasil-9) vaccines in Chinese populations, including two studies showing long-term efficacy (≥8 years) for the bvHPV and qvHPV vaccines. Real-world data from China are scarce. Although modeling studies in China show HPV vaccination is cost-effective, uptake and population coverage are relatively low. Various policies have been implemented to raise awareness and increase vaccine coverage, with the long-term aim of eliminating cervical cancer in China.

Abstract
This study investigated the influences of mother-daughter communication and social media on mothers' HPV vaccine refusal for their daughters aged 9-17. A cross-sectional online survey among 11,728 mothers of girls aged 9-17 in Shenzhen, China was implemented between July and October 2023. Multi-level logistic regression models were fitted. Among 11,728 participants, 43.2% refused to have their daughters receive an HPV vaccination. In multivariate analysis, more openness in the mother-daughter communication (AOR: 0.99, 95%CI: 0.98, 0.99), perceived more positive outcomes of mother-daughter communication (AOR: 0.77, 95%CI: 0.75, 0.79), higher frequency of exposure to testimonials about daughters' HPV vaccination (AOR: 0.81, 95%CI: 0.78, 0.85) and information encouraging parents to vaccinate their daughters against HPV on social media (AOR: 0.76, 95%CI: 0.73, 0.79), and thoughtful consideration of the veracity of the information specific to HPV vaccines (AOR: 0.80, 95%CI: 0.77, 0.83) were associated with lower vaccine refusal. Mothers who were not the main decision-makers of daughters' HPV vaccination (AOR: 1.28 to 1.46), negative outcome expectancies of mother-daughter communication (AOR: 1.06, 95%CI: 1.04, 1.08), and mothers' HPV vaccine refusal (AOR: 2.81, 95%CI: 2.58, 3.06) were associated with higher vaccine refusal for their daughters. The level of mothers' HPV vaccine refusal for their daughters was high in China. Openness and outcome expectancies of mother-daughter communication and information exposure on social media were considered key determinants of HPV vaccine refusal for daughters. Future HPV vaccination programs should consider these interpersonal factors.

Abstract
To investigate the HPV vaccine coverage and post-vaccination adverse reactions in Gansu Province, Western China, from 2018 to 2021. Data on suspected adverse reactions to HPV vaccines were collected from the Chinese Vaccine Adverse Event Following Immunization (AEFI). Estimate the incidence rates of Common Adverse Reaction and Rare Adverse Reaction. HPV vaccine coverage among females in different age groups was calculated using data from the Gansu Provincial Immunization Information Platform. The first-dose HPV vaccine coverage rate among females aged 9 to 45 was 2.02%, with the lowest rate of less than 1% observed in females aged 9 to 14. From 2018 to 2021, the incidence rates of Common Adverse Reaction and Rare Adverse Reaction reported in females after HPV vaccination were 11.82 and 0.39 per 100,000 doses, respectively. Common Adverse Reaction included fever (5.52 per 100,000 doses), local redness and swelling (3.33 per 100,000 doses), fatigue (3.15 per 100,000 doses), headache (2.76 per 100,000 doses), as well as local induration and nausea/vomiting (1.97 per 100,000 doses). Adverse reactions mainly occurred within 1 day after vaccination, followed by 1 to 3 days after vaccination. The HPV vaccine coverage rate among females aged 9 to 14 in Gansu Province is remarkably low, and there is an urgent need to enhance vaccine coverage. From 2018 to 2021, the incidence of Adverse reaction Following Immunization HPV vaccination fell within the expected range, indicating the vaccine's safety profile.

Abstract
This study described caregiver attitudes and the information sources they access about HPV vaccination for adolescents and determined their influence on human papillomavirus (HPV) vaccination initiation. An online survey was administered to 1,016 adults in July 2021. Participants were eligible if they were the caregiver of a child aged 9-17 residing in Mississippi, Arkansas, Tennessee, Missouri, and select counties in Southern Illinois. Multivariate logistic regression was used to estimate the association of caregiver attitudes and information sources with HPV vaccination. Information from doctors or healthcare providers (87.4%) and internet sources other than social media (31.0%) were the most used sources for HPV vaccine information. The highest proportion of caregivers trusted their doctor or healthcare providers (92.4%) and family or friends (68.5%) as sources of information. The HPV vaccine series was more likely to be initiated in children whose caregivers agreed that the vaccine is beneficial (AOR = 4.39, 95% CI = 2.05, 9.39), but less likely with caregivers who were concerned about side effects (AOR = 0.61, 95% CI = 0.42, 0.88) and who received HPV vaccination information from family or friends (AOR = 0.57, 95% CI = 0.35, 0.93). This study found that caregivers' attitudes, information sources, and trust in those sources were associated with their adolescent's HPV vaccination status. These findings highlight the need to address attitudes and information sources and suggest that tailored interventions considering these factors could increase HPV vaccination rates.

Abstract
Men who have sex with men and women (MSMW) have been reported to differ in psychosocial and sexual behavior patterns from men who have sex with men only (MSMO). However, results regarding the differences in HPV vaccination intention/behavior were inconclusive. We compared HPV vaccination intention between MSMO and MSMW and analyzed the differences in potentially associated factors in China. MSM participants were recruited online using a snowball sampling method. Cross-sectional data were collected via a questionnaire based on the extended information-motivation-behavioral skills model. Structural equation modeling was conducted to examine the relationship between the variables, followed by multi-group analysis to test differences between groups. Of 914 MSM, 77.68% were MSMO and 22.32% were MSMW. MSMW had a higher rate of reluctance to vaccinate than MSMO (23.53% vs. 16.20%, p = .016). Differences between the two groups were statistically significant in risky sexual behavior, behavioral skills, and promotional attitude. In both groups, promotional attitude was the most significant predictor of vaccination intention. Vaccination intention was directly influenced by motivation and indirectly by risky sexual behavior in MSMO, but not significantly in MSMW. Additionally, the direct effect of information on behavioral skills in MSMW was significantly greater than that in MSMO, but we did not find any effect of behavioral skills on vaccination intention. MSMW had lower vaccination intention than MSMO. MSMO may be influenced by risky sexual behavior and motivation, positively impacting their vaccination intention, unlike MSMW. Targeted strategies could help promote HPV vaccination, especially in MSMW.

Abstract
Few studies focused on human papillomavirus (HPV) in male patients. This study aimed to explore the detection rate and genotyping of HPV among male patients in Beijing to provide a reference for formulating prevention strategies for HPV infection. The cross-sectional study was conducted in Beijing Chaoyang Hospital from November 2015 to March 2023. It covered male patients from the urology and dermatology departments. Fifteen high-risk HPV genotypes were detected by the multiplex real-time polymerase chain reaction method. The overall detection rate of HPV was 25.19% (1288/5114, 95% confidence interval [CI] 24.00%-26.38%), of which the single infection rate was 16.99% (869/5114, 95% CI 15.97%-18.05%) and the co-infection rate was 8.19% (419/5114, 95% CI 7.46%-8.98%). The detection rate of HPV was 40.77% (521/1278), 35.58% (58/163), 32.69% (101/309), 31.91% (60/188), 12.63% (299/2367), and 32.35% (131/405) among male patients with balanitis, warts, rash, urethritis, prostatitis, and other urinary inflammation, respectively (P < 0.001). The top five HPV genotypes were HPV-52, HPV-58, HPV-16, HPV-51, and HPV-66. After the first positive HPV test, the proportion of male patients who turned negative was 22.47% within 3 months, 26.40% within 3-6 months, 24.72% within 6-12 months, 17.98% within 12-24 months, and 8.43% more than 24 months. The detection rate of HPV was high among male patients from the urology and dermatology departments in Beijing, which should be considered to develop HPV vaccines with better prevention effects.

Abstract
Despite successfully implementing the Human Papilloma Virus Vaccine (HPVV) program, Saskatchewan (SK) struggled to improve HPVV uptake rates. This suboptimal uptake of HPVV with a status quo of HPV-linked cervical cancer incidence rate is mainly because HPVV's impact on cancer prevention has not been realized adequately by vaccine providers and receivers. Further exploration of determinants of HPVV uptake is required to uncover high-resolution quality improvement targets for investment and situate contextually appropriate policies to improve its uptake. The study undertook a qualitative inquiry into understanding stakeholders' perspectives on HPVV experience through school-based programmes. It collected data through semi-structured initial interviews (N = 16) and follow-up interviews (N = 10) from across Saskatchewan's four Integrated Service Areas. Document analysis was conducted on all publicly available documents that included information on HPVV from January 2015 to July 2023. Thematic analysis of the data identified that inadequate information, awareness and education about HPV infection and HPVV among several groups, especially, parents, youth and school staff, was the main barrier to optimal HPVV uptake. Vaccine-related logistics, including the technical and text-heavy vaccine information sheet, understaffing, and time constraints, were other important factors that impeded HPVV uptake.

Abstract
Human papillomavirus (HPV) infections account for several human cancers. There is an urgent need to develop therapeutic vaccines for targeting preexisting high-risk HPV (such as HPV 16 and 18) infections and lesions, which are insensitive to preventative vaccines. In this study, we developed a lipid nanoparticle-formulated mRNA-based HPV therapeutic vaccine (mHTV), mHTV-02, targeting the E6/E7 of HPV16 and HPV-18. mHTV-02 dramatically induced antigen-specific cellular immune response and robust memory T-cell immunity in mice, besides significant CD8+ T-cell infiltration and cytotoxicity in TC-1 tumors expressing HPV E6/E7, resulting in tumor regression and prolonged survival in mice. Moreover, evaluation of routes of administration found that intramuscular or intratumoral injection of mHTV-02 displayed significant therapeutic effects. In contrast, intravenous delivery of the vaccine barely showed any benefit in reducing tumor size or improving animal survival. These data together support mHTV-02 as a candidate therapeutic mRNA vaccine via specific administration routes for treating malignancies caused by HPV16 or HPV18 infections.

Abstract
OBJECTIVE To develop theory-informed human papillomavirus (HPV) vaccine education materials that appeal to 18-26-year-olds. METHODS First, draft materials informed by Theory of Planned Behavior (TPB) and Health Belief Model (HBM) were developed. Next, an initial set of Consolidated Framework for Implementation Research (CFIR)-guided interviews were conducted with 18-26-year-old participants to receive feedback about content, format, appeal, implementation facilitators and barriers, and potential delivery modalities. Then, interviews were transcribed, coded, and analyzed using thematic analysis. Next, materials were modified based upon feedback. Finally, another set of interviews was conducted. RESULTS Most participants (n = 15) were female (93%), White (60%), and non-Hispanic (93%). All (100%) had heard of HPV and the HPV vaccine, and 80% reported having received the vaccine. Participant feedback on materials included emphasizing vaccine benefits and efficacy, rewording to enhance comprehension, and adding images represent diversity beyond race/ethnicity and sexual orientation. Suggested delivery methods included social media, print materials, and posters. CONCLUSION Qualitative interviews with young adults suggest that HPV education materials targeted to 18-26-year-olds should include health behavior theory-aligned messaging, inclusive imagery, and be disseminated through multiple modalities. PRACTICE IMPLICATIONS Providers should consider utilizing theory-based education materials that are relevant and appealing to young adults.

Abstract
PURPOSE To evaluate the awareness and existing knowledge of a portion of the Greek population about prevention, screening, and HPV vaccination. METHODS A questionnaire designed in Google forms has been distributed through social media between June 2021 and December 2021 in men and women aged > 16 years old. Statistical analysis was performed using the SPSS 20.0 program. Inferential analysis was performed to evaluate differences in responses among men and women. RESULTS We enrolled 2685 participants. Of those, 2285 were women, 386 were men, while 14 respondents chose not to respond to this question. Various age groups were detected with those aged between 26 and 30 years old being the predominant one. Participants with a higher education constituted 36.5% of the population. Most respondents were married (59.8%). In socioeconomic terms 75.5% of participants were employed whereas, monthly income ranged between 1000 and 1500 euros in the predominant group (36.8%). Only 40% of females and 3.9% of males were vaccinated against HPV. Adolescent immunization, acceptability rates reached 92.7% among female and 82.1% among male responders. Although, only a small proportion of the participants were not aware of the existence of HPV, 24.1% of males and 23.4% of females had the impression that condom use may provide absolute immunity to HPV and only 51.6% of males and 60.4% of females were aware about the high prevalence of HPV in the general population. Logistic regression analysis indicated that male participants as well as those aged > 50 years and those choosing to reject vaccination had decreased knowledge of the basic pathophysiology of HPV infection, as well as knowledge related to the existence and use of HPV DNA as a screening tool and the existence and efficacy of HPV vaccination. CONCLUSION Our results indicate that although awareness of the existence of HPV infection is high in Greek general population, the actual perception of the pathophysiology of transmission and importance of HPV testing and vaccination is low. Targeting specific population groups is essential to help increase HPV coverage and screening.

Abstract
BACKGROUND Cervical cancer is the eighth most prevalent cancer among women nationwide, with 358 new cases reported annually. One of the strategies to prevent it is getting vaccinated against the human papillomavirus (HPV), the leading cause of this cancer. METHODS A survey-based cross-sectional study was conducted in Riyadh, Saudi Arabia, to evaluate the acceptance of the HPV vaccine among parents of daughters and their knowledge of three domains: cervical cancer, HPV, and the HPV vaccine. RESULTS 390 parents participated in the study, with 88.2% female, 39.74% of the participants aged between 36-62 years old, and 62.56% holding a bachelor's degree or above. Parents were more aware of cervical cancer (78.97%), followed by HPV (50%) and the HPV vaccine (41.28%). Awareness levels about cervical cancer were significantly different among males and females, while awareness of HPV and the HPV vaccine was significantly associated with parents' education levels. For instance, parents with a bachelor's degree or higher (54.9%) demonstrated greater awareness of HPV compared to parents with a high school diploma (41.9%) or a middle school diploma or less (41.5%). The overall participants' knowledge scores in all three domains were poor, with an average below 50%. 60% of parents believed their daughters should receive the HPV vaccine. CONCLUSION More than half of the study participants are willing to vaccinate their daughters with the HPV vaccine despite their poor knowledge of the assessed domains. Awareness levels of HPV and the HPV vaccine are associated with education levels. We believe raising awareness among parents is necessary to improve the acceptance level of the HPV vaccine.

Abstract
Human papillomavirus (HPV) is associated with both benign and malignant disorders, such as genital warts and a variety of cancers, including oropharyngeal squamous cell carcinomas (OPSCCs). The current 9-valent HPV vaccine (Gardasil 9) protects against high-risk strains that have been shown to cause OPSCC, and widespread vaccination should reduce the rate of all HPV-associated cancers. HPV-related OPSCCs differ from non-HPV-related OPSCCs in their clinical presentations and responsiveness to treatment. To provide oral healthcare providers with a basis for effective com-munication with patients, this article will examine the evolution of the HPV vaccination schedule and the role of the HPV vaccine in the prevention of OPSCCs.

Abstract
PURPOSE Strengthening healthcare professionals' (HCPs) communication is an evidence-based approach to increasing human papillomavirus (HPV) vaccine uptake among adolescents. To better target future interventions, we sought to synthesize evidence on HCP subgroups who most need to improve their HPV vaccine recommendation quality. METHODS We searched five databases for quantitative studies published from 2012 to 2022 on HPV vaccine recommendation quality, including recommendation consistency and strength, for United States adolescents. Two coders independently abstracted data from each eligible study, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We summarized variation in recommendation quality by clinical and HCP characteristics. RESULTS The 28 eligible studies indicated that relatively low proportions of HCPs used higher-quality recommendation practices (median: 61% across 30 measures) and that recommendation quality varied across HCP subgroups. The most consistent findings were that more pediatric HCPs used higher-quality recommendations than family medicine HCPs (8 of 11 studies, 2-60 percentage point difference) and that HPV-related knowledge was associated with higher recommendation quality (four of seven studies). Most studies observed no differences in recommendation quality by clinical role (e.g., provider vs. nurse) or HCP demographics (e.g., gender, age, race/ethnicity). DISCUSSION Studies suggest a substantial need to improve HCPs' recommendation quality, with opportunities for targeting future interventions.

Abstract
The current study explores the risk communication conversations on Twitter and Instagram in the context of the 2019 HPV Awareness Day, through the theoretical lenses of the stigma associated with HPV, HPV-related cancer, and the HPV vaccine. Our findings reveal that: 1) self and enacted stigma are present in these social media conversations, via nonprofits and official ambassadors, and via regular people; 2) other categories related to stigma, which can be seen as reactions to stigma and appeals to better individuals and society (i.e. stopping stereotypes) also emerged in these conversations, via official and not official sources, pro and against vaccine discourses; and 3) the same categories emerged from the data via both platforms, but differences exist in terms of narratives and messaging. Practical implications are discussed.

Abstract
OBJECTIVES Adolescents and young adults are the main target population for human papillomavirus (HPV). The study aimed to investigate school students' HPV vaccination intentions and explore the contributing factors from a socio-ecological perspective. DESIGN A questionnaire survey was conducted in three secondary schools and three colleges in China. SAMPLE A total of 1756 students aged 14-22 years participated in this study. Among the 1756 participants, 182 students have received the HPV vaccine. For the remaining 1574 students, we analyzed their HPV vaccination intentions and the influencing factors. MEASUREMENTS Survey items for sociodemographics, knowledge and awareness of HPV, sexual intercourse and sexual knowledge, subjective socioeconomic status, self-efficacy, eHealth literacy, perceived social support from family, and the availability of HPV vaccine information were measured. RESULTS Only 182 (10.4%) had received the HPV vaccine among the 1756 participants. Among the remaining 1574 students, the majority of the students (1403, 89.1%) were willing to receive the HPV vaccine. Binary logistic regression analysis showed that students who were female, had lower self-efficacy, scored higher on sexual knowledge, believed vaccination preventing related diseases, worried about side effects after vaccination, thought oneself at risk of contracting HPV, had higher family support, knew the availability of the HPV vaccine in Mainland China from healthcare institutions, and with family residence in rural areas were more willing to receive the HPV vaccine. CONCLUSIONS Students had high HPV vaccination intentions while had low vaccination rate. Intrapersonal, interpersonal and institutional or community factors predicted HPV vaccination intention. Public health nurses in communities and schools could target the modifiable factors to promote students' HPV vaccine uptake.

Abstract
BACKGROUND Up-to-date (UTD) of the human papillomavirus (HPV) vaccine series has been low despite 2016 recommendations for 2 doses among initiators <15 years of age and 3 doses for 15+ year olds. This study examined how age at initiation affected the association between race/ethnicity and UTD among adolescent HPV vaccine initiators. We also examined how administration of other adolescent vaccines affected UTD. METHODS A secondary analysis of The National Immunization Survey - Teen data between 2016 and 2020 was conducted. Characteristics associated with initiation of the vaccine series was examined and used to evaluate UTD among initiators. All data were weighted. Associations between characteristics and HPV vaccine initiation were examined using Rao Scott chi-square tests and univariable logistic regression. Multivariable binary logistic regression models stratified by race/ethnicity calculated the strength of association between independent variables and odds of initiation and UTD among initiators. RESULTS The final sample size was 99,719 with 67,855 (68.1 %) initiating HPV vaccination. Among HPV vaccine initiators, Hispanic and black adolescents had lower odds of UTD. However, 9-10-year-old initiators had increased odds (aOR: 5.71; 95 %CI: 3.78-8.63) of UTD compared to 12-year-old initiators. Increased odds of UTD among initiators younger than 12 years were found across racial/ethnic groups. Flu vaccination was associated with decreased odds of UTD among white (aOR: 0.76; 95 %CI:0.65-0.88) and black adolescents (aOR: 0.67; 95 %CI: 0.46-0.96). CONCLUSION Strong recommendations to ensure patients are UTD on the HPV vaccine series are essential to improving UTD among all adolescents and follow-up should occur when administering other vaccines to reduce missed opportunities.

Abstract
BACKGROUND The vaccine coverage against human papillomavirus (HPV) vaccination remains low in France. The objective of this study was to study adolescent perceptions by comparing boys and girls, in order to build effective school-based interventions. METHODS This paper presents a cross-sectional study in French middle school pupils. They completed online questionnaires on their knowledge and attitudes toward the HPV vaccine, HPV vaccination status, their intention, reasons to vaccinate or not to vaccinate, and psychological antecedents of vaccination. A structural equation modeling (SEM) analysis was used to test the hypothesized model. RESULTS The participants are 818 pupils aged from 12 to 16 years (Mage = 13.78). Most pupils were in the pre-contemplative stage (62.7 % of boys and 40.8 % of girls). SEM analysis indicated that the relationship between the level of HPV knowledge, the representations of vaccines in general, and vaccine intention was mediated by attitudes towards the HPV vaccine among both boys and girls. CONCLUSIONS These findings reveal a high percentage of boys who do not feel concerned by the HPV vaccine and highlight the need to consider the psychological antecedents of vaccination in general in addition to the specific attitudes to the HPV vaccine.

Abstract
Cervical cancer is a significant public health concern in Ethiopia. It is mainly caused by persistent infection with the human papillomaviruses. The aim of this study was to assess the relationship between carcinogenic risk of probable, possible and low risk HPV infection and those of cervical intraepithelial neoplasia (CIN) and cervical cancer. A cross sectional study nested from prospective cohort study was conducted in Bahir Dar, northwest Ethiopia. Statistical analyses were performed using SPSSversion 26.0. HPV-16 was associated with a relatively higher risk of CIN II+, (AOR = 15.42; 95% CI 6.81-34.91). In addition, HPV-52, -18, -53 and -58, were significantly associated with an increased risk of CIN II+, (AOR = 7.38 (1.73-31.54), 5.42 (1.61-18.31), 4.08 (1.53-10.87), and 3.17 (1.00-10.03)), respectively. The current study shows high rate of HPV with predominance of HPV-16, -53, -58, -18, -35, and -52. The quadrivalent and nonavalent vaccine had only covered 27.1% and 45% of the circulating HPV genotypes. Ethiopia may need to consider introduction of nonavalent vaccine into the national public health strategy. Polyvalent vaccine which includes the genotypes not covered by existing approved vaccines should be considered.

Abstract
BACKGROUND Child vaccinations are among the most effective public health interventions. However, wide gaps in child vaccination remain among different groups with uptake in most minorities or ethnic communities in Europe substantially lower compared to the general population. A systematic review was conducted to understand health system barriers and enablers to measles, mumps and rubella (MMR) and human papilloma virus (HPV) child vaccination among disadvantaged, minority populations in middle- and high-income countries. METHODS We searched Medline, Cochrane, CINAHL, ProQuest and EMBASE for articles published from 2010 to 2021. Following title and abstract screening, full texts were assessed for relevance. Study quality was appraised using Critical Appraisal Skills Program checklists. Data extraction and analysis were performed. Health system barriers and enablers to vaccination were mapped to the World Health Organization health system building blocks. RESULTS A total of 1658 search results were identified from five databases and 24 from reference lists. After removing duplicates, 1556 titles were screened and 496 were eligible. Eighty-six full texts were assessed for eligibility, 28 articles met all inclusion criteria. Factors that affected MMR and HPV vaccination among disadvantaged populations included service delivery (limited time, geographic distance, lack of culturally appropriate translated materials, difficulties navigating healthcare system), healthcare workforce (language and poor communication skills), financial costs and feelings of discrimination. CONCLUSION Policymakers must consider health system barriers to vaccination faced by disadvantaged, minority populations while recognizing specific cultural contexts of each population. To ensure maximum policy impact, approaches to encourage vaccinations should be tailored to the unique population's needs. A one-size-fits-all approach is not effective.

Abstract
Human papillomavirus (HPV) vaccine introduction is anticipated in many countries in the coming years. This Perspective addresses the opportunities and challenges of introducing HPV vaccination in Pakistan. A substantial portion of the population within the high-risk age group necessitates the implementation of a robust vaccination strategy. Advocacy, community mobilization, and stakeholder engagement are the key elements for the successful implementation of the vaccination program. However, for long-term control strategies, a multifaceted approach is recommended. This approach should involve integrating HPV vaccination into the national immunization program, improving access to screening methods, and establishing comprehensive and cost-effective programs for preventing cervical cancer.

Abstract
BACKGROUND Increasing countries are expanding the human papillomavirus (HPV) vaccination to men, which has not yet been licensed in China. This study investigated the parental willingness to accept (WTA) and pay (WTP) HPV vaccine for their sons aged 9-14. METHODS In Shanghai, a metropolis area of China, parents with boys aged 9-14 were recruited to complete an online questionnaire using a convenience sampling strategy. Parental WTA were determined for parents themselves and for their sons. Parental preference of HPV vaccine was measured using discrete choice experiment in two assumed government subsidy scenarios that referred to HPV vaccination subsidy mechanisms for girls in China. Additionally, parental WTP was estimated using contingent valuation method. RESULTS A total of 2493 parents with boys aged 9-14 were included in the study. Majority of mothers (88.99 % and 90.99 %) and fathers (79.57 % and 85.04 %) showed WTA HPV vaccine for themselves and sons, respectively. Parental gender, age, monthly household income, knowledge, and awareness were positively associated with parental WTA for their sons (each P < 0.05). Remarkably, more mothers showed specific preference of HPV vaccine for themselves (53.67 %) and sons (47.78 %), while more fathers showed no preference for themselves (46.76 %) and sons (53.81 %). In the two assumed government subsidy scenarios, parents mostly preferred domestic HPV vaccines for themselves and sons (each P < 0.05). Additionally, mothers had significantly higher WTP for sons (mean value, 2122.75 CNY) than fathers did (1695.40 CNY) (P < 0.001). However, parental WTP was similar between for themselves and for sons, regardless of mothers and fathers (each P > 0.05). CONCLUSION Parents have high WTA and WTP HPV vaccine for boys aged 9-14 in Shanghai, which may provide evidence for preparing HPV vaccination strategy. Acceptance of HPV vaccines and roll-out in boys could be enhanced through the availability of government subsidy mechanism and domestic HPV vaccines.

Abstract
BACKGROUND World Health Organization human papillomavirus (HPV) vaccination recommendations include a single- or two-dose schedule in individuals 9-20 years old and advice for generating data on single-dose efficacy or immunobridging. The ongoing Phase 3 trial of Innovax's bivalent (types 16 and 18) HPV vaccine (Cecolin®) assesses in low- and middle-income countries alternative dosing schedules and generates data following one dose in girls 9-14 years old. Interim data for the 6-month dosing groups are presented. METHODS In Bangladesh and Ghana, 1,025 girls were randomized to receive either two doses of Cecolin at 6-, 12-, or 24-month intervals; one dose of Gardasil® followed by one dose of Cecolin at month 24; or two doses of Gardasil 6 months apart (referent). Serology was measured by enzyme-linked immunosorbent assay (ELISA) and, in a subset, by neutralization assays. Primary objectives include immunological non-inferiority of the Cecolin schedules to referent one month after the second dose. Safety endpoints include reactogenicity and unsolicited adverse events for 7 and 30 days post-vaccination, respectively, as well as serious adverse events throughout the study. RESULTS Interim analyses included data from the two groups on a 0, 6-month schedule with 205 participants per group. One month after Dose 2, 100% of participants were seropositive by ELISA and had seroconverted for both antigens. Non-inferiority of Cecolin to Gardasil was demonstrated. Six months following one dose, over 96% of participants were seropositive by ELISA for both HPV antigens, with a trend for higher geometric mean concentration following Cecolin administration. Reactogenicity and safety were comparable between both vaccines. CONCLUSIONS Cecolin in a 0, 6-month schedule elicits robust immunogenicity. Non-inferiority to Gardasil was demonstrated one month after a 0, 6-month schedule. Immunogenicity following one dose was comparable to Gardasil up to six months. Both vaccines were safe and well tolerated (ClinicalTrials.gov No. 04508309).

Abstract
BACKGROUND Cervical cancer eradication is one of the main goals for 2030 by the World Health Organization, which can only be achieved with high vaccination rates against Human Papilloma Virus. In Colombia, more and better scientific evidence is required to increase confidence in vaccination. The objective of this study is to evaluate the safety profile of the quadrivalent vaccine against HPV in the risk of developing autoimmune, neurological, and hematological diseases in adolescent women in Colombia. METHODS We designed a cohort study based on national HPV vaccination records and incident diagnostic data for the diseases of special interest during 2012 and 2021. We included adolescent women between 9 and 19 years old and compared vaccinated and non-vaccinated cohorts using an Inverse Probability of Treatment Weighting (IPWT) method for each scenario disease and follow-up period (180 and 360 days). FINDINGS The Odds Ratio (OR) of developing diseases of interest was estimated during two follow up periods, 180 and 360 days after the follow-up index date (Vaccination Day). The OR for developing rheumatoid arthritis was 4·4; CI95% (1·74 - 11·14), juvenile idiopathic arthritis was 2·76 IC95% (1·50 - 5·11), idiopathic thrombocytopenic purpura was 2·54 IC95% (1·28 - 5·02) and thyrotoxicosis was 2·86 IC95% (1·03 - 7·95), when comparing the vaccinated versus unvaccinated population. However, the temporal distribution of cases incident did not reveal a clear difference between the cohorts, since the rate of appearance of new cases has a constant linear behavior for the two groups. INTERPRETATION For rheumatoid arthritis, juvenile idiopathic arthritis, idiopathic thrombocytopenic purpura, and thyrotoxicosis; the application of the vaccine had an effect on the development of the disease. Nevertheless, our results should be interpreted with caution and be further studied, considering that the biological plausibility of the events occurred without a clear temporal pattern in relation to the exposure to the vaccine.

Abstract
This study aims to examine the factors associated with the level of HPV infection and HPV vaccine awareness among rural African Americans living in the Black Belt region of Alabama. A cross-sectional survey on cancer screening and health behaviors was conducted in the Black Belt region of Alabama. Adults (18 years or older) recruited through convenience sampling completed the self-administered survey. Binary logistic regressions were conducted to identify factors associated with HPV infection and HPV vaccine awareness among African American participants. Slightly more than half of the participants were aware of HPV (62.5%) and HPV vaccine (62.1%). Married or partnered participants had lower awareness of HPV or HPV vaccine. Family cancer history and self-reported health status were positively associated with both HPV and HPV vaccine awareness. In addition, employment was positively associated with HPV awareness, and participation in social groups was positively associated with HPV vaccine awareness. Tailored educational interventions that consider our findings might increase HPV and HPV vaccine awareness and contribute to better vaccine uptakes.

Abstract
Previous research has shown that women's use of a carrageenan gel reduces the risk of acquiring genital human papillomavirus (HPV) infections but does not help to clear existing ones. Although gel use may not result in complete clearance, it may decrease the viral load of HPV infections. We tested this hypothesis in the Carrageenan-gel Against Transmission of Cervical Human papillomavirus (CATCH) randomized controlled trial. Participants of the CATCH study were selected for viral load testing if they had completed the first four study visits and tested positive for HPV42 or HPV51 in at least one of these visits. HPV42 and HPV51 were chosen as they were among the most abundant low- and high-risk types, respectively, in the study sample. We measured viral load with a type-specific real-time polymerase chain reaction. Results were displayed using summary statistics. Of 461 enrolled participants, 39 were included in the HPV42 analysis set and 56 in the HPV51 analysis set. The median time between visits 1 and 4 was 3.7 months. The viral load (copies/cell) of HPV42 ranged from <0.001 to 13 434.1, and that of HPV51 from <0.001 to 967.1. The net median change in HPV42 viral load over all four visits was -1.04 copies/cell in the carrageenan and -147 copies/cell in the placebo arm (Wilcoxon rank sum test, p = 0.26). There was no net median change in HPV51 viral load over all four visits in either arm (p = 0.45). The use of a carrageenan-based gel is unlikely to reduce the viral load of HPVs 42 or 51.

Abstract
The purpose of this study was to understand the perceptions of HPV vaccination barriers and factors among parents or guardians of American Indian adolescents in the Cherokee Nation. Fifty-four parents of American Indian adolescents in the Cherokee Nation participated in one of eleven focus group discussions from June to August 2019. Discussions were recorded, transcribed, coded, and analyzed for themes. Protection against cancer was the primary parent-reported reason for vaccinating their children against HPV. The lack of information and safety concerns about the HPV vaccine were the main reasons for non-vaccination. To increase HPV vaccine uptake, parents strongly supported offering vaccinations in school. Furthermore, increased healthcare provider-initiated discussion can ease parental concerns about HPV vaccine safety and improve coverage.

Abstract
The present qualitative study is a part of the process evaluation of a complex intervention, the randomized controlled trial, "Prevention of human papillomavirus (HPV) in a school-based setting." We aimed to explore participating school nurses' perceptions and experiences of delivering the educational HPV intervention to adolescents aged 16. Focus group interviews were conducted with school nurses (n = 20) and analyzed with inductive qualitative content analysis. The overall theme Easily adapted into the existing role as a school nurse permeated the participants' views. The nurses were in favor of delivering an intervention that increased the HPV vaccination rates and improved beliefs and awareness about HPV prevention. It suits their work and health-promoting aspect of their role well and can easily be adapted into the current school health consultant curriculum. Having material in different languages to share with adolescents and their parents to promote equal health was deemed important.

Abstract
OBJECTIVE To date, no data supports the execution of vaccination after hysterectomy for high-grade cervical intraepithelial neoplasia (CIN2+) and early-stage cervical cancer. We aim to evaluate the potential effect of vaccination after hysterectomy for high-grade cervical intraepithelial neoplasia and early-stage cervical cancer. METHODS This is a multi-center retrospective study evaluating data of women who develop lower genital tract dysplasia (including anal, vulvar and vaginal intra-epithelial neoplasia) after having hysterectomy for CIN2+ and FIGO stage IA1- IB1 cervical cancer. RESULTS Overall, charts for 77 patients who developed lower genital tract dysplasia were collected. The study population included 62 (80.5%) and 15 (19.5%) patients with CIN2+ and early-stage cervical cancer, respectively. The median (range) time between hysterectomy and diagnosis of develop lower genital tract dysplasia was 38 (range, 14-62) months. HPV types covered by the nonavalent HPV vaccination would potentially cover 94.8% of the development of lower genital tract dysplasia. Restricting the analysis to the 18 patients with available HPV data at the time of hysterectomy, the beneficial effect of nonvalent vaccination was 89%. However, considering that patients with persistent HPV types (with the same HPV types at the time of hysterectomy and who developed lower genital tract dysplasia) would not benefit from vaccination, we estimated the potential protective effect of vaccination to be 67% (12 out of 18 patients; four patients had a persistent infection for the same HPV type(s)). CONCLUSIONS Our retrospective analysis supported the adoption of HPV vaccination in patients having treatment for HPV-related disease. Even in the absence of the uterine cervix, HPV vaccination would protect against develop lower genital tract dysplasia. Further prospective studies have to confirm our preliminary research.

Abstract
BACKGROUND Many countries have implemented active surveillance (ie, leaving the lesion untreated) as an option among younger women with cervical intraepithelial neoplasia grade 2 because regression rates are high and excisional treatment increases the risk for preterm birth in subsequent pregnancies. However, early identification of women at increased risk for progression to cervical intraepithelial neoplasia grade 3 or worse is important to ensure timely treatment. Because women who have received a human papillomavirus vaccine have a lower risk for cervical cancer, they may have a lower risk for progression of untreated cervical intraepithelial neoplasia grade 2 to cervical intraepithelial neoplasia grade 3 or worse. OBJECTIVE This study aimed to investigate if women who received a human papillomavirus vaccine and who are undergoing active surveillance for cervical intraepithelial neoplasia grade 2 are less likely to progress to cervical intraepithelial neoplasia grade 3 or worse when compared with women who did not receive the vaccine. STUDY DESIGN We conducted a population-based cohort study in Denmark using data from national health registers. We identified all women aged 18 to 40 years who were undergoing active surveillance for cervical intraepithelial neoplasia grade 2 from January 1, 2007, to December 31, 2020. Women with a previous record of cervical intraepithelial neoplasia grade 2 or worse, hysterectomy, or a loop electrosurgical excision procedure were excluded. Exposure was defined as having received ≥1 dose of a human papillomavirus vaccine at least 1 year before the cervical intraepithelial neoplasia grade 2 diagnosis. We used cumulative incidence functions to estimate the risk for progression to cervical intraepithelial neoplasia grade 3 or worse within 28 months using hysterectomy, emigration, and death as competing events. We used modified Poisson regression to calculate crude and adjusted relative risks of progression during the 28-month surveillance period. Results were stratified by age at vaccination and adjusted for index cytology, disposable income, and educational level. RESULTS The study population consisted of 7904 women of whom 3867 (48.9%) were vaccinated at least 1 year before a diagnosis of cervical intraepithelial neoplasia grade 2. At the time of cervical intraepithelial neoplasia grade 2 diagnosis, women who were vaccinated were younger (median age, 25 years; interquartile range, 23-27 years) than those who were not (median age, 29 years; interquartile range, 25-33 years). The 28-month cumulative risk for cervical intraepithelial neoplasia grade 3 or worse was significantly lower among women who were vaccinated before the age of 15 years (22.9%; 95% confidence interval, 19.8-26.1) and between the ages of 15 and 20 years (31.5%; 95% confidence interval, 28.8-34.3) when compared with women who were not vaccinated (37.6%; 95% confidence interval, 36.1-39.1). Thus, when compared with women who were not vaccinated, those who were vaccinated before the age of 15 years had a 35% lower risk for progression to cervical intraepithelial neoplasia grade 3 or worse (adjusted relative risk, 0.65; 95% confidence interval, 0.57-0.75), whereas women who were vaccinated between the ages of 15 and 20 years had a 14% lower risk (adjusted relative risk, 0.86; 95% confidence interval, 0.79-0.95). For women who were vaccinated after the age of 20 years, the risk was comparable with that among women who were not vaccinated (adjusted relative risk, 1.02; 95% confidence interval, 0.96-1.09). CONCLUSION Women who were vaccinated and who were undergoing active surveillance for cervical intraepithelial neoplasia grade 2 had a lower risk for progression to cervical intraepithelial neoplasia grade 3 or worse during 28 months of follow-up when compared with women who were not vaccinated but only if the vaccine was administered by the age of 20 years. These findings may suggest that the human papillomavirus vaccination status can be used for risk stratification in clinical management of cervical intraepithelial neoplasia grade 2.

Abstract
OBJECTIVES Cervical cancer accounts for 10 percent of cancer deaths among women in India. The human papillomavirus (HPV) vaccine can protect against infection but it is not included in India's universal immunisation programme. This study aimed to assess the demand and willingness to pay for the HPV vaccine among mothers of adolescent daughters. METHODS We conducted a contingent valuation exercise involving a hospital-based cross-sectional study to assess the demand for an HPV vaccine among mothers of adolescent daughters, their willingness to pay and its determinants. Participants were recruited at a tertiary care civil hospital in the city of Gurgaon in North India, and data was collected from December 2018 to February 2019. A questionnaire was administered to obtain demographic and awareness indicators. Payment cards were used to elicit the willingness to pay amount. RESULTS Out of 319 respondents, 79% were willing to pay for the vaccine. The mean maximum willingness to pay was INR 629 (USD 35), which was less than the vaccine market price of INR 2000-3000 (USD 117-175) per dose. Participant age and number of children significantly influenced demand, while family income and awareness of cervical cancer influenced willingness to pay for the HPV vaccine. Participants were willing to spend between 3% and 34% of their monthly income on the vaccine. CONCLUSIONS High demand and low willingness to pay for the HPV vaccine indicate low value perception of the health outcome among mothers of adolescent children in India. A strategy aimed at a price reduction of the vaccine and increasing its demand through improved awareness is important. At the same time, subsidising the vaccine in the short run is needed.

Abstract
BACKGROUND Shared decision making between patients and their healthcare providers is recommended for use of the human papillomavirus (HPV) vaccine Gardasil 9 (9v-HPV) in women ages 27-45 years. We studied HPV vaccination as a treatment modality for patients undergoing colposcopy older than age 26 years who tested positive for high-risk subtypes of HPV (HR-HPV). METHODS A retrospective study (N.=155) was performed for patients that were evaluated for cervical dysplasia who tested positive for HR-HPV and received the 9v-HPV vaccine prior to repeat cervical cancer screening with co-testing. Demographic information, risk factors for cervical dysplasia, and treatment outcomes were assessed for response to vaccination as treatment. RESULTS Repeat co-testing was negative for HR-HPV in 76 patients (49%) and was positive in 79 patients (51%). A greater percentage of Hispanic patients cleared the virus and Black patients had a greater percentage of persistent HR-HPV on repeat co-testing (P=0.047). When comparing those who cleared the virus and those who had persistent HR-HPV, there were no differences observed for associated risk factors for dysplasia, HPV subtype, cytology or colposcopy results, vaccine dosing interval, or total number of vaccine doses received. CONCLUSIONS While the HPV vaccine is effective for prevention of infection by high-risk strains of HPV, it remains unclear whether 9v-HPV vaccine should be recommended as a treatment option in exposed patients beyond age 26. We recommend healthcare providers discuss usefulness of 9v-HPV vaccine with their unvaccinated patients 27 years and older at risk for cervical dysplasia.

Abstract
African American women suffer under the burden of cervical cancer as they are first in mortality, diagnosed at later stages, and have a survivorship rate that is lower than the national average. The aim of our review is to evaluate the effectiveness of cervical cancer screening and prevention interventions for African American women living in the United States and to assess their commitment to health equity. A literature search was conducted using PubMed, Embase, CINAHL, and Scopus using MeSH terms related to cervical cancer, human papillomavirus (HPV), screening and prevention, and African Americans. This resulted in 1970 articles. Studies were included if they promoted cervical screening or prevention, sampled African American women aged 18 and over, and evaluated interventions. Among the 23 articles that met inclusion criteria, there were a wide variety of intervention strategies, that is, community health workers, patient navigation, patient reminders, self-sampling collection, and HPV vaccination. Health education interventions, when coupled with patient navigation or community health workers, were effective in promoting screening participation (odds ratio: 2.43, 95% confidence interval: 1.47-4.02). There were mixed results regarding the incorporation of health equity principles. This review supports the importance of incorporating health equity principles and community based methods in screening and prevention interventions. Future research and practice should incorporate African American women's perspectives in intervention development and implementation.

Abstract
High-risk sexual behavior is the primary risk factor for the acquisition and persistence of human papillomavirus (HPV) infection and the development of HPV-associated diseases including cancer. Incidence of HPV infection is high among individuals in their late teens and early 20s. Thus, college students represent a historically high-risk group for HPV infection yet are also a group with the ability to independently access HPV vaccination for HPV prevention. To inform future interventions, we examined factors associated with HPV-associated risky sexual behaviors among sexually active college students. Data (N = 741) were from an anonymous online survey distributed to students at a public Midwestern university in 2021. The outcomes were HPV-associated sexual risk behaviors-number of oral or vaginal sexual partners [high (≥ 5) or low (< 5)] and age of oral or vaginal sexual debut [early (< 18 years) or late (≥ 18 years)]. Multivariable logistic regression models estimated the association between HPV-associated risky sexual behaviors and several predictors including age, gender, relationship status, academic level, country of birth, and rural-urban status. Among sexually active students, approximately 47% and 41% had a high number of lifetime vaginal and oral partners, respectively. Among the same group, 60% and 64% had early vaginal and oral sexual debut. Students who were single and dating (aOR = 1.93; 95% CI = 1.21, 3.08) or single and not dating (2.11; 1.28, 3.48) were more likely to have a high number of vaginal lifetime partners compared with married students. Single (vs. married) students were also about twice as likely to have a high number of oral lifetime partners. Relative to graduate students, freshmen/sophomores were more likely to have an early vaginal (2.44; 1.45, 4.11) and oral (2.14; 1.26, 3.63) sexual debut. Interventions tailored to college freshmen/sophomores and unmarried students should encourage students to receive the HPV vaccine for prevention of future HPV-associated diseases.

Abstract
Worldwide prevalence of cervical cancer decreased significantly with the use of human papilloma virus (HPV)-targeted prophylactic vaccines. However, these multivalent antiviral vaccines are inert against established tumors, which leave patients with surgical ablative options possibly resulting in long-term reproductive complications and morbidity. In an attempt to bypass this unmet medical need, we designed a new E7 protein-based vaccine formulation using Accum™, a technology platform designed to promote endosome-to-cytosol escape as a means to enhance protein accumulation in target cells. Prophylactic vaccination of immunocompetent mice using the Accum-E7 vaccine (aE7) leads to complete protection from cervical cancer despite multiple challenges conducted with ascending C3.43 cellular doses (0.5-, 1.0-, and 2.0 × 106 cells). Moreover, the humoral response induced by aE7 was higher in magnitude compared with naked E7 protein vaccination and displayed potent inhibitory effects on C3.43 proliferation in vitro. When administered therapeutically to animals with pre-established C3.43 or Tal3 tumors, the vaccine-induced response synergized with multiple immune checkpoint blockers (anti-PD-1, anti-CTLA4, and anti-CD47) to effectively control tumor growth. Mechanistically, the observed therapeutic effect requires cross-presenting dendritic cells as well as CD8 T cells predominantly, with a non-negligible role played by both CD4+ and CD19+ lymphocytes. good laboratory practice (GLP) studies revealed that aE7 is immunogenic and well tolerated by immunocompetent mice with no observed adverse effects despite the use of a fourfold exceeding dose. In a nutshell, aE7 represents an ideal vaccine candidate for further clinical development as it uses a single engineered protein capable of exhibiting both prophylactic and therapeutic activity.

Abstract
Due to the association with the causal HPV-16 infection, the oropharyngeal carcinoma spreads into two separate entities depending on HPV-16 positivity. More recent data show a diversified picture of the importance and prevalence of the surrogate parameter p16 (discordance) for a definitive HPV-16 association, which varies worldwide. In the context of prevention options, vaccination is of major and HPV screening of healthy people only of little importance.

Abstract
INTRODUCTION Women vaccinated through the initial catch-up HPV vaccination programme (2011/12 to 2013/14) first became eligible for cervical screening in 2019 at age 25. This study aims to examine the changes in detection of HG cytology outcomes in 25-year-olds screened from 2010 to 2022 compared to population data on HPV vaccination in this group. METHODS This was an ecological-type study. Cytology results from the CervicalCheck database from 2010 to 2022 (High Grade, Low Grade, and No Abnormality Detected) were plotted against data from the National Immunisation Office on the uptake of HPV vaccinations in females from 2010 to 2022. RESULTS Vaccination rates in the catch-up programme were lower (44-70%) than for routine HPV immunisation at age 12/13 in 2010/11 (81%). The rate of high-grade cytology in 25-year-olds in 2015-2018 was 3.7% of all cytology tests taken in this age group. For the corresponding period from 2019 to 2022 (when vaccinated women were attending screening), the average percentage of HG cytology in 25-year-olds was 1.5%, representing a significant reduction in HG cytology proportions (p < 0.001). CONCLUSION This study provides early evidence of the potential impact of HPV vaccination on cervical disease in the Republic of Ireland. Despite lower vaccination uptake in the initial catch-up group, we are seeing early signs of the positive protective effect of HPV vaccination in women at the time of their first cervical screening test. Plans to incorporate individual-level HPV vaccination status for women on the cervical screening register will allow more detailed assessment of the impact of HPV vaccination.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is a promising step toward cervical cancer elimination. This study was conducted to investigate the knowledge, attitude, and HPV vaccine uptake among female adults in mainland China based on a large e-commerce platform. METHODS We conducted a cross-sectional online survey of female adults between March 4 to April 20, 2022. The survey consisted of sociodemographic information, related knowledge, vaccination uptake, and attitudes toward vaccination. We included women aged 18-45 years in the final analysis. Logistic regressions were conducted to explore influencing factors associated with related knowledge, HPV vaccination uptake, and willingness to be vaccinated. RESULTS In total, 3,572 female adults (34 years, IQR 30-39) were included in the analysis. The majority of the participants were highly educated (78.7%) with a high monthly family income (79.0%). The median HPV knowledge score was 8.25 out of 11. More than 75% of respondents were unvaccinated, while 95.8% of unvaccinated female adults are willing to be vaccinated. Variables such as age, insurance, vaccination history, and whether one had heard of the HPV vaccine influence HPV vaccination practice (all p-values < 0.05). The main barriers to vaccination were vaccine inaccessibility and the high cost of the vaccine. CONCLUSION The findings of our study highlight a moderate knowledge level, poor vaccination rate, and strong willingness to be vaccinated among Chinese female adults who were better educated and wealthier. Targeted health education and practical support should be provided in the future, to reduce gaps between vaccine uptake and vaccine acceptance.

Abstract
INTRODUCTION The purpose of this DNP project was to establish baseline human papillomavirus (HPV) vaccination rates, improve baseline knowledge of HPV and HPV vaccines, reduce barriers to HPV vaccination, and increase intention of HPV vaccine uptake among college students. METHODS A precaution adoption process model-based survey, in-person education session, and posteducation survey were administered to college students in a Midwestern university to measure perceptions of HPV and HPV vaccination as well as to identify barriers to HPV vaccination. RESULTS From the preeducation survey to the posteducation survey, correct answers to questions increased, and barriers and misconceptions about HPV and the HPV vaccine decreased, indicating successful education. HPV vaccination intent, defined as indication of "likely" or "very likely" to receive the vaccine on the surveys, rose from 28.0% to 90.7% among participating college students. CONCLUSION This study showed that implementing engaging, in-person HPV prevention education is an effective method for decreasing barriers related to vaccination and increasing vaccination intention.
