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
There is a continued need for research to better understand the influence social media has on parental vaccination attitudes and behaviors, especially research capturing the effects of the COVID-19 pandemic. The goal of this study was to explore parents' perspectives related to the impact the pandemic had on 1) social media engagement, 2) vaccine messaging on social media, and 3) factors to guide future intervention development. Between February and March 2022, 6 online, synchronous, text-based focus groups were conducted with parents of adolescents aged 11 to 17 years. Participants who all utilized social media were recruited from across the United States. Qualitative data were analyzed using content analysis. A total of 64 parents participated. Average age was 47 years, and participants were predominantly White (71.9%), female (84.3%), and engaged with social media multiple times per day (51.6%). Participants (95.3%) viewed obtaining all recommended vaccines as important or very important; however, overall vaccination rates for their adolescents were varied (50% ≥1 dose HPV; 59.4% MenACWY; 78.1% Tdap; 65.6% Flu; 81.3% COVID-19). Three themes emerged highlighting the pandemic's impact on parent's (1) general patterns of social media use, (2) engagement about vaccines on social media and off-line behaviors related to vaccination, and (3) perspectives for developing a credible and trustworthy social media intervention about vaccination. Participants reported fatigue from contentious vaccine-related content on social media and desired future messaging to be from recognizable health institutions/associations with links to reputable resources. Plus, providers should continue to provide strong vaccine recommendations in clinic.

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
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
Vaccination is the principal strategy for primary prevention of infection by Human Papilloma Virus (HPV), which causes different pathological conditions, up to cancer, in both males and females. However, to date, knowledge among adolescents and their parents about the HPV vaccine is still low. The aim of this quasi-experimental, multicenter study is to assess the effectiveness of a digital educational intervention, conducted by a multidisciplinary health-care team including a Community Nurse, to increase adolescents' HPV vaccination uptake, their knowledge, self-efficacy, feelings and involvement in HPV vaccine decision-making, and parents' vaccination hesitancy. The study will be carried out among a population of students (and their parents), aged between 11 and 13, at secondary schools in Italy. Validated questionnaires will be administered to both students and parents at baseline (T0) and 3 months after a digital educational intervention (T1). The findings may be useful in evaluating and deepening a methodology for designing and implementing educational interventions, embedded in the school setting, that could promote the achievement of outcomes within the broader process of youth's health promotion.

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
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
Despite the ongoing global vaccination campaign aimed at preventing human papillomavirus (HPV) related health issues, the uptake of the HPV vaccine remains unacceptably low in developing regions, particularly in sub-Saharan Africa (SSA). Therefore, this systematic review and meta-analysis aimed at determining the pooled prevalence and associated factors of HPV vaccine uptake among adolescent school girls in SSA. Electronic bio-medical databases were explored. Pooled prevalence, publication bias, meta-regression, sub-group, and sensitivity analysis were performed. The estimated pooled prevalence of HPV vaccine uptake was 28.53% [95% CI: (5.25, 51.81)]. Having good knowledge and a positive attitude was significantly associated with HPV vaccine uptake in SSA. Subgroup analysis revealed the highest uptake was 62.52% from Kenya and the lowest was 3.77% in Nigeria. The HPV vaccine uptake is low. It underscores the need for community education, school-based immunization, and education programs that promote the uptake of the vaccine to increase coverage.

Abstract
OBJECTIVE The study aimed to assess the level of knowledge of patients with cervical cancer referred to radiation oncology outpatient clinics in Turkey regarding screening methods and human papillomavirus (HPV) vaccination and increase social awareness based on the findings. METHODS A descriptive cross-sectional survey was conducted from January to June 2022 involving 300 patients in various regions. Data on demographics, cervical cancer screening and HPV vaccination knowledge, and recommendations to relatives were collected through a questionnaire-based interview. Univariate logistic regression analyzed the impact of independent variables on knowledge levels. RESULTS Among the participants, 57% were unaware of cervical cancer screening, and 66% had no knowledge of the HPV vaccine. Higher knowledge levels were associated with higher education, older age at marriage and first birth, and previous gynecological checkups. Lower knowledge levels were observed in patients treated at state institutions, with no formal education, and diagnosed with cervical cancer at age 60 or older. A significant inverse correlation was found between knowledge levels and the stage of cancer at diagnosis, with higher awareness in earlier stages. CONCLUSION The study revealed limited awareness among cervical cancer patients in Turkey regarding screening and HPV vaccination. Lower knowledge levels were associated with specific demographic factors, emphasizing the importance of targeted educational campaigns to reduce the burden of cervical cancer and promote early detection. Efforts to enhance vaccination coverage and encourage early screening can significantly improve outcomes. Comprehensive awareness surveys are essential in guiding policymaking and implementing effective early detection and prevention strategies for cervical cancer.

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
PURPOSE The incidence of anal cancer is on the rise in the US, especially among high-risk groups. This study examined the prevalence and determinants of awareness of the causal relationship between HPV and anal cancer among US adults. METHODS Study data was obtained from the 2017 to 2020 iterations of the Health Information National Trends Survey. The prevalence of awareness that HPV causes anal cancer was estimated among HINTS respondents who were aware of HPV in general. Survey weights were used to provide estimates representative of the adult US population. Multivariable logistic regressions were used to examine the associations between awareness that HPV causes anal cancer and cancer-related behaviors/perceptions and sociodemographic characteristics of respondents. RESULTS Two thousand six hundred and eighty four (27.2%) of the study population were aware that HPV caused anal cancer. Those of gay sexual orientation were more aware than heterosexuals [OR 2.27; 95% CI (1.24, 4.14)]. Compared to respondents with a high school diploma or less, individuals with some college education [OR 1.38; 95% CI (1.03, 1.85)] and those with at least a college degree [OR 1.52; 95% CI (1.17, 1.98)] were more likely to be aware. Participants who had positive cancer information seeking behavior were more aware of the HPV-anal cancer link compared to those who did not [OR 1.57; 95% CI (1.30, 1.89)]. CONCLUSION Population-level awareness that HPV causes anal cancer remains critically low in the US. Sexual orientation, level of education and cancer information seeking behavior are associated with increased awareness of the causal relationship between HPV and anal cancer. Efforts should be directed toward addressing the awareness gap among individuals with lower education levels and promoting curiosity-driven information seeking behaviors.

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
BACKGROUND There have been declines in global immunisation coverage due to the COVID-19 pandemic. Recovery has begun but is geographically variable. This disruption has led to under-immunised cohorts and interrupted progress in reducing vaccine-preventable disease burden. There have, so far, been few studies of the effects of coverage disruption on vaccine effects. We aimed to quantify the effects of vaccine-coverage disruption on routine and campaign immunisation services, identify cohorts and regions that could particularly benefit from catch-up activities, and establish if losses in effect could be recovered. METHODS For this modelling study, we used modelling groups from the Vaccine Impact Modelling Consortium from 112 low-income and middle-income countries to estimate vaccine effect for 14 pathogens. One set of modelling estimates used vaccine-coverage data from 1937 to 2021 for a subset of vaccine-preventable, outbreak-prone or priority diseases (ie, measles, rubella, hepatitis B, human papillomavirus [HPV], meningitis A, and yellow fever) to examine mitigation measures, hereafter referred to as recovery runs. The second set of estimates were conducted with vaccine-coverage data from 1937 to 2020, used to calculate effect ratios (ie, the burden averted per dose) for all 14 included vaccines and diseases, hereafter referred to as full runs. Both runs were modelled from Jan 1, 2000, to Dec 31, 2100. Countries were included if they were in the Gavi, the Vaccine Alliance portfolio; had notable burden; or had notable strategic vaccination activities. These countries represented the majority of global vaccine-preventable disease burden. Vaccine coverage was informed by historical estimates from WHO-UNICEF Estimates of National Immunization Coverage and the immunisation repository of WHO for data up to and including 2021. From 2022 onwards, we estimated coverage on the basis of guidance about campaign frequency, non-linear assumptions about the recovery of routine immunisation to pre-disruption magnitude, and 2030 endpoints informed by the WHO Immunization Agenda 2030 aims and expert consultation. We examined three main scenarios: no disruption, baseline recovery, and baseline recovery and catch-up. FINDINGS We estimated that disruption to measles, rubella, HPV, hepatitis B, meningitis A, and yellow fever vaccination could lead to 49 119 additional deaths (95% credible interval [CrI] 17 248-134 941) during calendar years 2020-30, largely due to measles. For years of vaccination 2020-30 for all 14 pathogens, disruption could lead to a 2·66% (95% CrI 2·52-2·81) reduction in long-term effect from 37 378 194 deaths averted (34 450 249-40 241 202) to 36 410 559 deaths averted (33 515 397-39 241 799). We estimated that catch-up activities could avert 78·9% (40·4-151·4) of excess deaths between calendar years 2023 and 2030 (ie, 18 900 [7037-60 223] of 25 356 [9859-75 073]). INTERPRETATION Our results highlight the importance of the timing of catch-up activities, considering estimated burden to improve vaccine coverage in affected cohorts. We estimated that mitigation measures for measles and yellow fever were particularly effective at reducing excess burden in the short term. Additionally, the high long-term effect of HPV vaccine as an important cervical-cancer prevention tool warrants continued immunisation efforts after disruption.

Abstract
INTRODUCTION Despite documented effectiveness in preventing several cancers, genital warts and safety of Human Papillomavirus (HPV) vaccine, immunization coverage among French adolescents remains far from the 80 % target. University health students (HS) in France may promote HPV vaccine through a national service (Service Sanitaire des Etudiants en Santé). We aimed to evaluate intentions to recommend the HPV vaccine to friends and relatives, to receive HPV vaccine, and to identify factors associated with these attitudes. METHODS We conducted a cross-sectional survey in five French Universities from October 2019 to February 2020, using a self-administered online questionnaire. We used bivariable and multivariable logistic regression models to identify determinants of behavior around HPV vaccine: (i) individual intention for vaccination, and (ii) vaccine recommendation to friends and relatives. RESULTS Among the 732 respondents (180 men, 552 women), 305 (41.7%) reported previous HPV vaccination (54.5 % among women), 504 (68.9%) would recommend the HPV vaccine to friends and relatives, 532 (72.7%) respondents would be vaccinated today if it was recommended for them. Intentions to recommend or to receive the HPV vaccine were less frequent in nursing students compared to medical and pharmacy students. After adjustment for demographical factors, HPV vaccine knowledge was associated with intention [aOR 1.30 (95%-confidence interval, 1.15-1.47)] and recommendation [1.26 (1.10-1.45)], respectively. Additionally, adjusting for knowledge about HPV infections, and confidence in vaccines in general was associated with vaccine intention [1.55, (1.30-1.84)] and recommendation [1.52 (1.24-1.86)]. HPV-vaccinated HS were more prone to recommend the HPV vaccine to friends and relatives [10.9 (6.6-17.9)]. CONCLUSION A majority of HS would accept and/or recommend HPV vaccines. HS with greater knowledge about the HPV vaccine were more prone to recommend it. Strengthening knowledge about HPV and its vaccination is probably necessary before their Involvement in a HPV immunization program.

Abstract
BACKGROUND International data on anogenital HPV infection incidence among men are limited. METHODS Incidence of incident-persistent (IP) anogenital HPV infections was evaluated among 295 men who have sex with men (MSM) and 1576 heterosexual men (HM) aged 16-27 years in the placebo arm of a global, multicenter 4-valent (4v) HPV vaccine trial. We estimated IP incidence (penile/scrotal, perineal/perianal, anal) for 4vHPV and 9-valent (9v) HPV vaccine types and cumulative IP incidence over 36 months. RESULTS IP infection incidence per 100 person-years (95% CI) among HM for 4vHPV and 9vHPV types was 4.1 (3.5-4.9) and 6.8 (5.9-7.6) at penile/scrotal, and 1.2 (.8-1.6) and 1.9 (1.5-2.4) at perineal/perianal sites, respectively; and among MSM, IP infection incidence was 2.3 (1.3-3.8) and 3.2 (2.0-4.9) at penile/scrotal, 6.8 (4.9-9.2) and 9.0 (6.9-11.6) at perineal/perianal, and 12.0 (9.4-15.1) and 16.8 (13.7-20.2) at anal sites, respectively. Cumulative IP incidence over 36 months (excluding anal canal; any 9vHPV type) was higher among MSM versus HM (24.1% vs 18.4%). CONCLUSIONS A substantial proportion of unvaccinated men of catch-up vaccination age developed IP 9vHPV-related infections. Gender-neutral vaccination could decrease male HPV infection, contribute to herd protection, and reduce disease burden. Clinical Trials Registration. NCT00090285.

Abstract
BACKGROUND We assessed whether five geographic-based socioeconomic factors (medically underserved area (MUA); healthcare provider shortage area (HPSA); persistent poverty; persistent child poverty; and social vulnerability index (SVI)) were associated with the odds of HPV vaccination initiation, series completion, and parental vaccine hesitancy, and whether the observed relationships varied by gender of the child. METHODS An online panel service, administered through Qualtrics®, was used to recruit parents of adolescents 9-17 years of age to complete a one-time survey in 2021. Coverage of the panel included five US states: Arkansas, Mississippi, Missouri, Tennessee, and Southern Illinois. Generalized estimating equation (GEE) models were used to assess population-level associations between five geographic-based socioeconomic factors (MUA; HPSA; persistent poverty; persistent child poverty; and SVI) and three HPV vaccination outcomes (initiation, series completion, and hesitancy). All GEE models were adjusted for age of child and clustering at the state level. RESULTS Analyses were conducted using responses from 926 parents about their oldest child in the target age range (9-17 years). The analytic sample consisted of 471 male children and 438 female children across the five states. In adjusted GEE models, persistent child poverty and HPSA were negatively associated with HPV vaccination initiation and series completion among female children, respectively. Among male children, high social vulnerability was negatively associated with HPV vaccine series completion. Additionally, persistent poverty and high social vulnerability were negatively associated with HPV vaccine hesitancy in male children. CONCLUSIONS The results of this cross-sectional study suggest that geographic-based socioeconomic factors, particularly, HPSA, persistent poverty, and SVI, should be considered when implementing efforts to increase HPV vaccine coverage for adolescents. The approaches to targeting these geographic factors should also be evaluated in future studies to determine if they need to be tailored for male and female children.

Abstract
BACKGROUND Although HPV prophylactic vaccines can provide effective immune protection against high-risk HPV infection, studies have shown that the protective effect provided by them would decrease with the increased age of vaccination, and they are not recommended for those who are not in the appropriate age range for vaccination. Therefore, in those people who are not suitable for HPV prophylactic vaccines, it is worth considering establishing memory T-cell immunity to provide long-term immune surveillance and generate a rapid response against lesional cells to prevent tumorigenesis. METHODS In this study, healthy mice were preimmunized with LM∆E6E7 and LI∆E6E7, the two Listeria-vectored cervical cancer vaccine candidate strains constructed previously by our laboratory, and then inoculated with tumor cells 40 d later. RESULTS The results showed that preimmunization with LM∆E6E7 and LI∆E6E7 could establish protective memory T-cell immunity against tumor antigens in mice, which effectively eliminate tumor cells. 60% of mice preimmunized with vaccines did not develop tumors, and for the remaining mice, tumor growth was significantly inhibited. We found that preimmunization with vaccines may exert antitumor effects by promoting the enrichment of T cells at tumor site to exert specific immune responses, as well as inhibiting intratumoral angiogenesis and cell proliferation. CONCLUSION Altogether, this study suggests that preimmunization with LM∆E6E7 and LI∆E6E7 can establish memory T-cell immunity against tumor antigens in vivo, which provides a viable plan for preventing tumorigenesis and inhibiting tumor progression.

Abstract
BACKGROUND The gynaecological care of women with Multiple Sclerosis has received little attention; most reports focussed on pregnancy or sexuality. The objective of the present study was to evaluate if gynaecological follow-up for women of reproductive age with Multiple Sclerosis was adequate. METHODS We performed a cross-sectional study on a large cohort of women with Multiple Sclerosis aged 18-40 years. All participants completed online questionnaires on general health status, gynaecological follow-up, and sexuality. Expanded Disability Status Scale (EDSS) scores were extracted from medical records. The study was registered in clinicaltrials.gov with the number NCT05248438, and in the European database ID-RCB with the number 2021-A02912-39. RESULTS Of the 192 patients who completed questionnaires, 157 (82.2%) reported gynaecological follow-up. Of the 155 patients on immunosuppressive treatments, only 31 (20%) underwent annual cervical screening. Of the 140 patients who met the French papillomavirus vaccination age recommendations, only 50 (35.7%) were vaccinated. A total of 128 (66.7%) patients used contraception. However, 16 (8.3%) patients reported unplanned pregnancies since the time of diagnosis. CONCLUSION Women with Multiple Sclerosis require more information on reproductive health and prevention of cancer. Better contraceptive advice would reduce the number of unplanned pregnancies and avoid foetal exposure to potentially teratogenic treatment.

Abstract
ABSTRACT Despite the proven effectiveness of human papillomavirus (HPV) vaccination, this vaccine is underused in the United States and is associated with many disparities and barriers to acceptance. Adolescent HPV vaccination rates failed to meet the Healthy People 2020 goal of 80% vaccine coverage when nearly all other routine adolescent vaccines met or were near this goal. When introducing the HPV vaccine series, many clinicians use a conversational approach, although years of research show that an announcement approach is more effective at increasing HPV vaccination rates. This article reviews current HPV vaccine communication practices used by clinicians and recommends evidence-based best practices to improve adolescent HPV vaccination rates in the United States.

Abstract
BACKGROUND The first randomised controlled trial of single-dose human papillomavirus (HPV) vaccine efficacy, the Kenya single-dose HPV-vaccine efficacy (KEN SHE) trial, showed greater than 97% efficacy against persistent HPV16 and HPV18 infection at 36 months among women in Kenya. We compared antibody responses after one dose of HPV vaccine in the Dose Reduction Immunobridging and Safety Study (DoRIS), the first randomised trial of the single- dose regimen in girls aged 9-14 years, the target age range for vaccination, with those after one dose of the same vaccine in KEN SHE. METHODS In the DoRIS trial, 930 girls aged 9-14 years in Tanzania were randomly assigned to one, two, or three doses of the 2-valent vaccine (Cervarix) or the 9-valent vaccine (Gardasil-9). The proportion seroconverting and geometric mean concentrations (GMCs) at month 24 after one dose were compared with those in women aged 15-20 years who were randomly assigned to one dose of the same vaccines at the same timepoint in KEN SHE. Batched samples were tested together by virus-like particle ELISA for HPV16 and HPV18 IgG antibodies. Non-inferiority of GMC ratios (DoRIS trial:KEN SHE) was predefined as a lower bound of the 95% CI less than 0·50. FINDINGS Month 24 HPV16 and HPV18 antibody GMCs in DoRIS were similar or higher than those in KEN SHE. 2-valent GMC ratios were 0·90 (95% CI 0·72-1·14) for HPV16 and 1·02 (0·78-1·33) for HPV18. 9-valent GMC ratios were 1·44 (95% CI 1·14-1·82) and 1·47 (1·13-1·90), respectively. Non-inferiority of antibody GMCs and seropositivity was met for HPV16 and HPV18 for both vaccines. INTERPRETATION HPV16 and HPV18 immune responses in young girls 24 months after a single dose of 2-valent or 9-valent HPV vaccine were comparable to those in young women who were randomly assigned to a single dose of the same vaccines and in whom efficacy had been shown. A single dose of HPV vaccine, when given to girls in the target age range for vaccination, induces immune responses that could be effective against persistent HPV16 and HPV18 infection at least two years after vaccination.

Abstract
PURPOSE Human papillomavirus (HPV) is the most commonly transmitted sexually transmitted infection. HPV infections have been on the rise among males, especially in the form of oropharyngeal cancer. Despite this, there is a gap in healthcare guidelines to increase HPV vaccine administration among males. In this study, we focus on the Indigenous population of North America and Oceania to determine existing barriers resulting in low HPV vaccination rates among the population. METHOD We surveyed peer-reviewed literature on the awareness of HPV infection among Indigenous males in North America and Oceania. Using keywords HPV plus male, men or boy, and ethnical filters such as Indigenous, Aboriginal or First Nations, we retrieved 54 articles based on titles, of which 15 were included after reading the abstracts. RESULTS Reported HPV awareness was generally low in Indigenous males in North America, with no peer-reviewed data from Oceania. The lower understanding by males compared to females was largely attributable to misconceptions about HPV-related diseases, their transmission, and prevention. Lack of awareness and concern toward the risk of contracting HPV infection in Indigenous males suggests an impediment in disseminating health information about this cancer-causing virus. CONCLUSION Culturally sensitive education, with emphasis on Indigenous males, is needed to improve this group's HPV knowledge. Researchers should also engage meaningfully with Indigenous communities by building rapport to achieve a positive change in attitude.

Abstract
OBJECTIVE This study evaluated the impact of the COVID-19 pandemic and vaccine perceptions on Human Papillomavirus (HPV) vaccine hesitancy. Secondary endpoints included comparing COVID-19 and HPV vaccination trends regarding time, community of residence, and unmet social needs. METHODS This was a survey-based, cross-sectional study that included 101 participants who were recruited through the Wyandotte County Public Health Department. Participants were eligible for inclusion in this study if they were a parent/guardian of one or more children aged 13 to 17; English- or Spanish-speaking. This study took place in Wyandotte County, Kansas. Descriptive statistics and chi-square analyses were utilized. RESULTS There was no difference in completion of COVID-19 and HPV vaccines (p = 0.0975). Significantly more individuals started and did not finish the HPV vaccine series compared to the COVID-19 vaccine series (p = 0.0004). Most participants indicated their opinion on the HPV vaccine had not changed due to the pandemic (71.3 %). Participants who felt familiar with HPV had higher rates of HPV vaccine completion. While 77 % of participants felt extremely or moderately familiar with HPV, 61.4 % were unaware of its association with oropharyngeal cancer. CONCLUSION There was minimal change in parents' perception of the HPV vaccine due to the COVID-19 pandemic despite decreased rates of vaccination during this time. HPV vaccine series completion was significantly lower than COVID-19 vaccine series completion, highlighting a need to improve HPV vaccine completion counseling. Additionally, patient education should address the knowledge gap discovered regarding the link between HPV infection and oropharyngeal cancer.

Abstract
BACKGROUND Cervical cancer poses a heavy health burden in China, with the second highest incidence and mortality rate among female tumors, yet human papillomavirus (HPV) vaccination rate among female university students remain remains low. This study conducted a cross-sectional survey to assess the degree of HPV vaccine hesitancy among female university students and to explore the potential association between knowledge, risk perception, trust, and HPV vaccine hesitancy. METHODS A total of 1,438 female university students from four Chinese cities were recruited through stratified, multistage, cluster sampling method. The mediation model was constructed using the Bootstrap method, introducing trust and risk perception as mediating variables to examine the effect of knowledge on HPV vaccine hesitancy. RESULTS The study found that 8.9% (95%CI:7.4%∼10.4%) of the female university students exhibited HPV vaccine hesitancy. Pearson's correlation analysis revealed a negative association between vaccine hesitancy and knowledge, risk perception, and trust. The mediation model showed that knowledge had significant indirect effects on HPV vaccine hesitancy through trust (indirect effect: -0.224, 95% CI: -0.293 ∼ -0.167) and risk perception (indirect effect: -0.013, 95% CI: -0.033 ∼ -0.002). CONCLUSION HPV vaccine hesitancy among female university students has mitigated, but still needs to be addressed. In addition, trust and risk perception are mediators mediating the relationship between knowledge with HPV vaccine hesitancy. Therefore, there is a need to strengthen public health education to improve knowledge, with a particular focus on providing information about trust and risk perception to reduce HPV vaccine hesitancy.

Abstract
The Human Papillomavirus (HPV) infection is responsible for more than 80% of reported cervical cancer and other virus-associated tumours. Although this global threat can be controlled using effective vaccination strategies, a growing perturbation of HPV infection is an emerging coinfection likely to increase the severity of the infection in humans. Moreover, these coinfections prolong the HPV infections, thereby risking the chances for oncogenic progression. The present review consolidated the clinically significant microbial coinfections/co-presence associated with HPV and their underlying molecular mechanisms. We discussed the gaps and concerns associated with demography, present vaccination strategies, and other prophylactic limitations. We concluded our review by highlighting the potential clinical as well as emerging computational intervention measures to kerb down HPV-associated severities.

Abstract
OBJECTIVE China has a substantial disease burden of cervical cancer. To further understand preventive measures for reducing cervical cancer in China, this study aimed to correlate screening attendance and regular screening with human papillomavirus (HPV) vaccination among Chinese females. METHODS This prospective questionnaire-based survey recruited Chinese females aged 25 or above in Hong Kong by random digit dialing telephone interviews in 2022. The survey studied women's practice of cervical screening and adherence to regular screening. Variables including HPV vaccination status and attendance of physical check-ups were involved in the questionnaire. Screening uptake and screening adherence were the main outcomes, which were measured as the proportion of women who reported having attended a cervical screening and screened regularly, respectively. RESULTS Out of 906 valid respondents, the reported cervical screening uptake was over 70% among females aged 30 or above and particularly over 80% among women aged 35-59; however, the uptake was only 46% among those aged 25-29. Adherence to regular screening was 50%-60% across ages 25-59 years and dropped to approximately 40% for women older than 60 years. Both screening uptake and adherence were associated with HPV vaccination, with adjusted odds ratios of 2.37 and 2.23, respectively. A large proportion of regularly screened women may be overscreened for screening more frequently than recommended. CONCLUSION Responded Chinese females showed good cervical screening uptake but were moderately adherent to regular screening. Policymakers should emphasize the importance of regular screening and the recommended screening frequency by HPV vaccination status for better healthcare resource use.

Abstract
Vaccines to protect against human papillomavirus (HPV) infection are recommended for all adolescents by the World Health Organization (WHO) and are primarily delivered in school-based settings. This systematic review aims to summarize the available evidence on the cost of HPV vaccine delivery in low- and middle-income countries (LMICs). This updated evidence is eminent given recent global efforts to revitalize HPV vaccine delivery following the COVID-19 pandemic and can be used to inform planning for program sustainability. We carried out a systematic review of published literature reporting the costs of HPV vaccine delivery in LMICs published between 2005 and 2023. Eligibility criteria were developed using the Population, Intervention, Comparator, Outcome (PICO) framework, and studies that reported primary costing data and unit costs of HPV vaccine delivery were included. From the included studies, we extracted data such as phase of HPV vaccine implementation when costing was done, delivery strategy, and unit costs. Unit costs were converted into 2022 US$ for comparability. All included studies underwent critical appraisal using an adapted framework including Consolidated Health Economics Evaluation Reporting Standards criteria, the WHO-led consensus statement on vaccine delivery costing, and other frameworks. Our research identified 226 records, of which 15 met our inclusion criteria. Most studies (64 %) were carried out in African countries and during HPV vaccine pilots or demonstrations (60 %). Vaccine delivery cost ranged from $0.31 to $24.07 per dose for financial costs and $1.48 to $48.70 per dose for economic costs. The critical appraisal showed that most studies did not describe the uncertainty of reported delivery cost. Our systematic review evidence suggests that HPV vaccine delivery costs vary widely depending on country and stage of implementation when costing was done. Areas for further research include costing when programs are beyond the introduction phase and in LMICs outside of Africa.

Abstract
In vaccine development, broadly or cross-type neutralizing antibodies (bnAbs or cnAbs) are frequently targeted to enhance protection. Utilizing immunodominant antibodies could help fine-tune vaccine immunogenicity and augment the precision of immunization strategies. However, the methodologies to capitalize on the attributes of bnAbs in vaccine design have not been clearly elucidated. In this study, we discovered a cross-type neutralizing monoclonal antibody, 13H5, against human papillomavirus 6 (HPV6) and HPV11. This nAb exhibited a marked preference for HPV6, demonstrating superior binding activity to virus-like particles (VLPs) and significantly higher prevalence in anti-HPV6 human serum as compared to HPV11 antiserum (90% vs. 31%). Through co-crystal structural analysis of the HPV6 L1 pentamer:13H5 complex, we delineated the epitope as spanning four segments of amino acids (Phe42-Ala47, Gly172-Asp173, Glu255-Val275, and Val337-Tyr351) on the L1 surface loops. Further interaction analysis and site-directed mutagenesis revealed that the Ser341 residue in the HPV6 HI loop plays a critical role in the interaction between 13H5 and L1. Substituting Ser341 with alanine, which is the residue type present in HPV11 L1, almost completely abolished binding activity to 13H5. By swapping amino acids in the HPV11 HI loop with corresponding residues in HPV6 L1 (Ser341, Thr338, and Thr339), we engineered chimeric HPV11-6HI VLPs. Remarkably, the chimeric HPV11-6HI VLPs shifted the high immunodominance of 13H5 from HPV6 to the engineered VLPs and yielded comparable neutralization titers for both HPV6 and HPV11 in mice and non-human primates. This approach paves the way for the design of broadly protective vaccines from antibodies within the main immunization reservoir.

Abstract
The psychosocial underpinnings of vaccine hesitancy are complex. Research is needed to pinpoint the exact reasons why people hesitate to vaccinate themselves or their children against vaccine-preventable diseases. One possible reason are concerns that arise from a misunderstanding of vaccine science. We examined the impact of scientific reasoning on vaccine hesitancy and human papillomavirus (HPV) vaccination intent through a cross-sectional study of parents of vaccine-eligible children (N = 399) at immunization clinics in Shanghai, China. We assessed the relationship between science reasoning and both vaccine hesitancy and HPV vaccine acceptance using general additive models. We found a significant association between scientific reasoning and education level, with those with less than a high school education having a significantly lower scientific reasoning that those with a college education (ß = -1.31, p-value = 0.002). However, there was little evidence of a relationship between scientific reasoning and vaccine hesitancy. Scientific reasoning therefore appears not to exert primary influence on the formation of vaccine attitudes among the respondents surveyed. We suggest that research on vaccine hesitancy continues working to identify the styles of reasoning parents engage in when determining whether or not to vaccinate their children. This research could inform the development and implementation of tailored vaccination campaigns.

Abstract
Human Papillomavirus (HPV) type variants have been classified into lineages and sublineages based upon their whole genome sequence. Here we have examined the specificity of antibodies generated following natural infection with lineage variants of oncogenic types (HPV16, 18, 31, 33, 45, 52 and 58) by testing serum samples assembled from existing archives from women residing in Africa, The Americas, Asia or Europe against representative lineage-specific pseudoviruses for each genotype. We have subjected the resulting neutralizing antibody data to antigenic clustering methods and created relational antigenic profiles for each genotype to inform the delineation of lineage-specific serotypes. For most genotypes, there was evidence of differential recognition of lineage-specific antigens and in some cases of a sufficient magnitude to suggest that some lineages should be considered antigenically distinct within their respective genotypes. These data provide compelling evidence for a degree of lineage specificity within the humoral immune response following natural infection with oncogenic HPV.

Abstract
Background This study aims to utilize the extended Theory of Planned Behavior (TPB) model to examine the intentions of clinical interns in China towards Human papillomaviruses (HPV) vaccination. It also fills a significant gap in the literature concerning vaccine acceptance in this specific population. Methods This cross-sectional study was carried out with clinical interns in Shandong Province, China, with a total of 1,619 participants. Data were collected through self-reported questionnaires, including demographic characteristics, TPB variables, and HPV-related health knowledge. Hierarchical regression analysis was employed to identify key factors influencing vaccination intentions, and Structural Equation Modeling (SEM) was used to analyze the interrelationships between these factors. Results This study initially identified key predictors affecting clinical interns' intentions to receive the HPV vaccine through hierarchical regression analysis. The preliminary model, which accounted for demographic factors, revealed foundational impacts of household income and HPV-related clinical experience on intentions. After integrating TPB variables-attitude, subjective norm, perceived behavioral control, and HPV-related health knowledge-the model's explanatory power was enhanced to 37.30%. SEM analysis focused on the interplay among TPB constructs and extended variables, confirming their significance in forming vaccination intentions, with subjective norm having the most substantial impact (β = 0.375, p < 0.001). The extended TPB model explained over half of the variance in vaccination intentions, substantiating the hypotheses and revealing the psychological determinants behind clinical interns' decision-making for HPV vaccination. Conclusion The extended TPB model from this study effectively explains the vaccination intentions among clinical interns for HPV, offering theoretical support for public health strategies and educational interventions targeting this group. These findings are of significant importance for public health practice and future health promotion strategies.

Abstract
BACKGROUND Routine vaccination coverage for adolescents living in the rural US is lower than adolescents living in urban areas. We sought to measure the effect of Boot Camp Translation (BCT), a community-based participatory intervention, on rural adolescent vaccination coverage. METHODS A cluster randomized controlled trial was performed September 2018-November 2021 involving 16 rural Colorado counties. Intervention county community members engaged in BCT to develop interventions to improve adolescent vaccination locally. Adolescent vaccination coverage was measured using the Colorado Immunization Information System. RESULTS For 11-12-year-olds, HPV initiation, HPV up-to-date, MenACWY, and Tdap vaccination coverage was lower post- versus pre-intervention in the control and intervention groups. For 11-12-year-olds in the intervention group, there was no significant difference post- versus pre-intervention in the odds of HPV vaccine initiation (adjusted ratio of odds ratios [aROR] = 0.93, 95 %: 0.85-1.02, p = 0.10) or up-to-date HPV vaccination (aROR: 1.10, 95 % CI: 0.98-1.23, p = 0.11) compared with the control group. Among 11-12-year-olds, the decrease in the proportion vaccinated with MenACWY and Tdap in the intervention group was significantly greater than the control group. Among 13-17-year-olds, there were significant increases in HPV initiation, HPV up-to-date, MenACWY, and Tdap vaccination coverage from pre- to post-intervention for both groups, with no significant differences between groups. CONCLUSION 11-12-year-old vaccination coverage decreased slightly from pre- to post-intervention while 13-17-year-old vaccination coverage increased. We saw no effect from the BCT intervention. Our findings about the effectiveness of BCT for improving vaccine uptake may not be generalizable because the study coincided with the COVID-19 pandemic. CLINICAL TRIAL REGISTRY This study was registered with ClinicalTrials.gov, NCT03955757.

Abstract
Background Human papillomavirus (HPV) can cause cancers in men and women. Despite the availability of an effective vaccine, HPV vaccination coverage remains suboptimal among college students. Literature showed that hesitancy for HPV vaccination is a leading barrier to the uptake in this group. However, prior interventions have shown limitations in reducing HPV vaccine hesitancy in college students. Thus, this study examined a conventional educational approach using a vaccine information statement (VIS), and subsequently explored college students' HPV vaccine hesitancy and the potential of virtual reality (VR) technology to overcoming the limitations of interventional efforts. Methods We employed a mixed-methods design along with convenience sampling, constituting a one-way pre- and post-intervention (HPV VIS) survey (Study A) and individual interviews (Study B). All data collections occurred with 44 college students at an urban public university at the mid-south region of the U.S. between October 2022 and April 2023. Study A assessed changes in HPV vaccination outcomes including knowledge, beliefs/attitudes, vaccine hesitancy, and intentions. Study B measured college students' primary reasons for HPV vaccine hesitancy and preferred strategies for the vaccination promotion including VR-based education. We conducted paired t-test and Wilcoxon signed ranks test for quantitative data and framework analysis for qualitative data. Results Participants reported significant improvements in knowledge [t(43) = 6.68, p < 0.001] regarding HPV vaccination between before and after reading the HPV VIS. No change was observed in beliefs/attitudes, vaccine hesitancy, and intentions. The framework analysis revealed college students' reasons for HPV vaccine hesitancy, needed information, and preferred strategies along with the potential of VR technology for future HPV vaccination education. Conclusion The findings provided essential information on designing HPV vaccination information focused on vaccine hesitancy among college students. Future research should consider these findings in developing interventions including VR to increasing HPV vaccine acceptance among college students.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination has shown high efficacy against anal HPV infection and lesions in clinical trials, and the HPV prevalence and type distribution in anal precancers and cancer predict a high preventable potential for HPV vaccination. However, the real-world effectiveness of HPV vaccination against anal high-grade lesions and cancer is yet to be shown. METHODS We investigated HPV vaccine effectiveness against anal high-grade squamous intraepithelial lesion (HSIL) or worse in a nationwide cohort including all Danish women aged 17-32 years during October 2006 to December 2021 (n = 968 881). HPV vaccinations and first occurrence of anal HSIL or worse were retrieved from nationwide registries. Women were considered vaccinated after first dose and classified by age at vaccination. Using Cox regression, hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated for anal HSIL or worse according to vaccination status. RESULTS During follow-up, the number of incident histological anal HSIL or worse cases was 37 in unvaccinated women, and less than 5 and 26 in women vaccinated at ages younger than 17 years and 17-32 years, respectively. The overall number of cancers was less than 5. Compared with unvaccinated women, the risk of histological anal HSIL or worse was reduced for women vaccinated at age younger than 17 years (HR = 0.30, 95% CI = 0.10 to 0.87). For women vaccinated at age 17-32 years, the hazard rate of anal HSIL or worse was 1.21 (95% CI = 0.73 to 2.03). CONCLUSION This is the first study to demonstrate that HPV vaccination at a younger age is associated with substantially reduced risk of anal HSIL or worse in the general population.

Abstract
Misinformation, disinformation, and conspiracy theories about vaccines are key drivers of vaccine hesitancy. A repeated false claim about COVID-19 vaccines is that the vaccines cause female infertility. Dating back decades, various conspiracy theories have linked vaccination programs with infertility and thus harmed vaccination programs in Africa, Asia, and Central America, particularly against polio and tetanus. In the United States, Europe, and Australia, human papilloma virus (HPV) vaccines have been falsely blamed for infertility and primary ovarian insufficiency (POI). After distribution of COVID-19 vaccines began in December 2020, almost immediately there arose conspiracy theories claiming that these vaccines cause menstrual irregularities, miscarriages, and infertility, promoted by noted antivaccine activists Robert F. Kennedy, Jr. and Andrew Wakefield among others. Here we will explore the history of this antivaccine narrative, how it has been promulgated in the past and repurposed to COVID-19 vaccines, and strategies to counter it.

Abstract
OBJECTIVE Cervical screening is a life-saving intervention, which reduces the incidence of and mortality from cervical cancer in the population. Human papillomavirus (HPV) based screening modalities hold unique promise in improving screening accuracy. HPV prevalence varies markedly by age, as does resultant cervical intraepithelial neoplasia (CIN), with higher rates recorded in younger women. With the advent of effective vaccination for HPV drastically reducing prevalence of both HPV and CIN, it is critical to model how the accuracy of different screening approaches varies with age cohort and vaccination status. This work establishes a model for the age-specific prevalence of HPV factoring in vaccine coverage and predicts how the accuracy of common screening modalities is affected by age profile and vaccine uptake. DESIGN Modelling study of HPV infection rates by age, ascertained from European cohorts prior to the introduction of vaccination. Reductions in HPV due to vaccination were estimated from the bounds predicted from multiple modelling studies, yielding a model for age-varying HPV and CIN grades 2 and above (CIN2+) prevalence. SETTING Performance of both conventional liquid-based cytology (LBC) screening and HPV screening with LBC reflex (HPV reflex) was estimated under different simulated age cohorts and vaccination levels. PARTICIPANTS Simulated populations of varying age and vaccination status. RESULTS HPV-reflex modalities consistently result in much lower incidence of false positives than LBC testing, with an accuracy that improves even as HPV and CIN2+ rates decline. CONCLUSIONS HPV-reflex tests outperform LBC tests across all age profiles, resulting in greater test accuracy. This improvement is especially pronounced as HPV infection rates fall and suggests HPV-reflex modalities are robust to future changes in the epidemiology of HPV.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection in men and women in the United States (1). Vaccination prevents and controls HPV infection and associated outcomes, including genital warts, precancerous lesions, and certain cancers, such as cervical, vaginal, vulvar, anal, penile, and oropharyngeal (2,3). HPV vaccination in the United States has been recommended for girls since 2006 and for boys since 2011 and requires multiple doses (2,3). This vaccine, targeted for children ages 11-12 years, may be started at age 9. This report uses parent-reported data from the 2022 National Health Interview Survey to describe the percentage of children ages 9-17 years who received at least one dose of the HPV vaccine by selected sociodemographic and health characteristics.

Abstract
OBJECTIVES HPV vaccination rates remain suboptimal despite proven efficacy. Data suggest misconceptions or lack of knowledge are leading barriers. Our study aimed to develop and pilot a novel interactive education resource designed to educate parents and patients about HPV vaccines. METHODS This is a prospective pilot study conducted in an urban teaching hospital pediatric clinic. The Patient Activated Learning System (PALS) intervention included 3 web-based videos with HPV vaccine-related educational content. Participants were parents of adolescent patients, aged 11-17 years, and young adult patients, aged 18-26 years. Enrolled participants completed an HPV vaccine knowledge survey before and after watching PALS; paired scores were evaluated. Acceptability and participant-reported impact of PALS modules were measured via Likert-scale surveys. RESULTS 132 individuals were approached; 101 (76%) enrolled and completed the study. Participants self-identified as Hispanic (50%), non-Hispanic Black (23%), non-Hispanic White (7%), Asian (6%), American/Alaskan/Hawaiian Native or Pacific Islander (5%). Half reported earning ≤$40,000 annually; 57% had only a high school education. Post-intervention knowledge scores were increased compared to baseline (9.87/27 points vs 17.53/27 points, p < 0.01). PALS modules were reported as enjoyable to use and understandable (89% and 93%, respectively), and improved participants' understanding of the importance of HPV vaccination (90%). Of the 18 patients unvaccinated at baseline, 39% received 1 shot of the HPV vaccine within one month. CONCLUSION The PALS HPV vaccine educational intervention was feasible, acceptable, and improved knowledge among a diverse, underserved population. Our intervention may positively influence HPV vaccination rates, with potential to overcome HPV vaccine hesitancy.

Abstract
OBJECTIVE The purpose was to determine the effectiveness of human papillomavirus immunization and its impact on cervical cancer development in Kazakhstan. METHODS The current research is a case-control study with two groups: a main group and a control group. A total of 725 subjects participated in the research. RESULTS The association between vaccination and cervical cancer development was calculated both for the two groups as a whole and for individual patients, who were selected based on criteria of residence, presence of immunodeficiency or chronic cardiac or renal pathology, as well as analysis of age at which the vaccine dose was received. There was a statistically significant association between the absence of the human papillomavirus vaccine and the risk of cervical cancer in all groups. When considering the entire cohort, the chance of finding a risk factor (lack of vaccination) was almost 7 times higher in the main group than in the control group. Thus, an association between vaccination and cervical cancer risk was found in each of the pairs of subjects. CONCLUSION The effectiveness of vaccination in preventing cervical cancer was not observed in patients who were vaccinated after 18 years of age, while most patients in the control group were vaccinated in their teens. The practical significance of the research is not only to further study the problem of human papillomavirus (HPV) vaccination in Kazakhstan but also to popularize HPV immunization to prevent cervical cancer (CC).

Abstract
OBJECTIVES Human papillomavirus (HPV) stands as one of the prevalent sexually transmitted infections (STIs) and serves as the primary factor behind nearly all instances of cervical cancer, along with various other non-cancerous conditions like genital warts. Our objective was to explore the knowledge and beliefs of Greek parents regarding HPV infection and the vaccination of boys against HPV. METHODS A cross-sectional study took place at a university hospital located in the Peloponnese region of Greece, from January to June 2021. The study employed convenience sampling as its methodology, and data gathering involved the distribution of self-administered questionnaires to parents who had at least one son between the ages of 9 and 18 years. RESULTS The final sample consisted of 120 individuals. 65.8 % of parents have been informed about HPV vaccination, knew that the HPV vaccine provides immunity against genital warts (50 %), and that minimum of two doses is necessary (46.7 %). 30.8 % intended to vaccinate their boys against HPV if the vaccine were available for males. The most important reasons for vaccination were the perception that both genders share equal responsibility in the prevention of sexually transmitted infections (91.7 %) and the protection against cancer (87.6 %), whereas the fear of adverse reactions and the adequate knowledge about HPV-related diseases were most reported as reasons of the intentions to not vaccinate their sons with 31.7 % and 25.8 % respectively. CONCLUSIONS Although parents participating in the study know about HPV, however, there are significant lack of knowledge regarding HPV infection and the vaccine effects, which can significantly affect the acceptance of vaccination for boys.

Abstract
INTRODUCTION Approximately 42.5% of adults aged 18-59 in the United States is estimated to be affected by human papillomavirus (HPV) infection. However, Asian Americans have the lowest HPV vaccination initiation rate compared to other racial groups. This study aims to explore the experiences of HPV and the HPV vaccination among ethnic Korean women and men in the United States. METHODS A total of 33 ethnic Korean and Korean Americans aged 27-45 years living in the U.S. were recruited via word-of-mouth and social media using a purposive sampling strategy. They participated in an online survey. Of the 33 participants, 29 (14 females and 15 males) participated in in-depth interviews via password-protected Zoom. A content analysis approach was used to analyze the interviews. RESULTS Only 32% of participants had received the HPV vaccine at least once (female: 35.3%, male: 12.5%). Six major themes emerged from data analysis: (1) awareness of HPV, HPV vaccine, and HPV-associated cancers; (2) attitudes toward the HPV vaccine; (3) barriers to HPV vaccination; (4) women's experiences and preferences for pap smear testing; (5) experiences with HPV diagnosis; and (6) HPV and HPV vaccination education preferences. CONCLUSION The findings highlight cultural factors that may impede the discussion about and uptake of HPV vaccination and HPV-associated cancer screening, which emphasize the need for culturally appropriate interventions to overcome stigma around HPV and enhance vaccination rates. Healthcare providers should consider ethnic and cross-cultural differences perceptions to effectively HPV-related health information. This study provides insight into the experiences and understanding of HPV and vaccination among ethnic Korean men and women, laying the groundwork for developing culturally-tailored programs that sim to increase HPV vaccination rates and mitigate the stigma and impact of HPV-related disease in this community.

Abstract
Disparities persists in HPV awareness and vaccination among different racial and ethnic groups. We assessed disparities in awareness of HPV and the HPV vaccine among non-Hispanic Black US adults. We analyzed the nationally representative data from the Health Information National Trends Survey of US adults 18 years or older (n = 16,092) administered by the National Cancer Institute (HINTS5-Cycle 1,2,3,4) for the years 2017-2020, of which 2,011 (n = 2,011) were non-Hispanic Black adults. Weighted Poisson regression models were used to estimate disparities in HPV and HPV vaccination awareness among non-Hispanic Black US adults. In the US, 63.2% of non-Hispanic Black adults had heard of HPV and 57.6% were aware of the HPV vaccine. Black females had 1.3 and 1.5 times the prevalence of HPV and the HPV vaccine awareness compared to males (PR = 1.3; 95% CI = 1.2-1.4; P ≤ 0.001) and (PR = 1.5; 95% CI = 1.4-1.6; P ≤ 0.001) respectively. Blacks with a college education had 1.8 and 2.2 times the prevalence of HPV and HPV vaccine awareness (PR = 1.8; 95% CI = 1.4-2.4; P ≤ 0.001) and (PR = 2.2; 95% CI = 1.8-2.7; P ≤ 0.001) respectively, compared to those with less than a high school education. Compared to 2017, Black adults with ≤ $35K income were less aware about HPV in 2020. There was evidence of disparities in HPV and HPV vaccine awareness among non-Hispanic Blacks. To foster improvements in HPV vaccine uptake and reduce disparities in HPV-associated cancers, future interventions must target men and disadvantaged populations, for whom awareness gaps exist.

Abstract
Immunogenicity of Two or Three Doses of 9vHPV VaccineThis noninferiority trial examined two versus three doses of 9-valent human papillomavirus (9vHPV) vaccine in individuals 15 to 26 years of age in the United States. In an unplanned interim analysis of female participants, two doses of 9vHPV vaccine appeared to elicit similar rates of seroconversion and antibody titers for each of the nine HPV genotypes to three doses at 1 month postvaccination.

Abstract
OBJECTIVES In Mayotte, cervical cancer represents the second cause of cancer mortality in women. Vaccination coverage against papillomavirus and screening rates are difficult to quantify but among the lowest in France. Added to this is an under-calibrated health system, which does not allow optimal treatment of cancers on site. The objective of the study was to study the elements that would increase papillomavirus vaccination among general practitioners. METHODS We carried out a qualitative study of phenomenological inspiration using semi-directed open interviews. The target population was private general practitioners based in Mayotte. The analysis was done by coding verbatim statements, from which emerged general themes, to build a model. RESULTS Twenty-two interviews were conducted. Vaccination was part of a context and was organized around the trio doctor-patient-institutions. The main pillar to vaccination was information, which could concern doctors or patients. The information delivered to patients through the media, campaigns in schools, and vaccination obligation were the main elements. The study revealed positive emotional dynamics of on-site HPV vaccination. CONCLUSION This study made it possible to better understand the ecosystem in which papillomavirus vaccination takes place in Mayotte, and to identify elements of vaccination promotion. Vaccination school campaigns should keep going on to increase vaccination uptake.

Abstract
This study investigated the efficacy of the prophylactic human papillomavirus (HPV) vaccine, which was initiated between 2009 and 2013 in Japan. The study involved 1529 eligible women aged 16-39 years who visited 11 outpatient clinics in Japan for various reasons. These patients underwent HPV genotype analysis and a Pap test of cervical cell samples. A total of 299 women (19.6%) had received the prophylactic HPV vaccine (bivalent:quadrivalent vaccine ratio = 2:1). Of the 5062 participants in the Japanese Human Papillomavirus Disease Education and Research Survey (J-HERS 2011), which was conducted in the pre-vaccination era, 3236 eligible participants were included as controls. In this study (J-HERS 2021), the highest rate of HPV vaccination (53%) was observed in patients aged 22-27 years. Vaccinated individuals exhibited a 49% rate of protection against low-grade intraepithelial lesions (LSILs) and atypical squamous cells, not excluding high-grade squamous intraepithelial lesions (ASCH) or worse (LSIL/ASCH+), and a 100% rate of protection against high-grade squamous intraepithelial lesions (HSILs) or worse (HSIL+). Significant reductions in HPV16 (95%) and HPV18 (100%) infections were noted, but no differences were observed in HPV6 and HPV11 infections. The prevalences of HPV51 and HPV59 increased with vaccination, although these changes were not confirmed in the comparative study with J-HERS 2011. Comparing the prevaccination (J-HERS 2011) and postvaccination (J-HERS 2021) periods, 43%, 51%, 88%, and 62% reductions in HPV16, HPV18, HPV16/18, and HPV31/58 infection rates were observed, respectively. Similarly, 62% and 71% reductions in LSIL/ASCH+ and HSIL+ rates were noted, respectively. There were 88% and 87% reductions in LSIL/ASCH+ and HSIL+ rates in 16-21- and 28-33-year-old patients, respectively. Bivalent or quadrivalent vaccines provided 100% protection against high-grade squamous cell lesions (suggestive of CIN2 or CIN3) in young women aged <39 years at 9-12 years after initiation of Japan's first nationwide HPV vaccination program. Cross-protection against HPV31 and HPV58 is likely to occur, although some HPV-type replacements are inconsistent across vaccination regimens. This demonstrates the effectiveness of the HPV vaccine. However, continuous monitoring of cervical cancer and precancer is necessary in younger generations (born 1997-2007), who were rarely vaccinated due to the prolonged suspension of the vaccine recommendations in Japan.
