Abstract
PURPOSE The prevalence of recommendation of human papillomavirus (HPV) vaccination by health care providers has improved over the last decade. However, research to determine whether the COVID-19 pandemic affected the progress in recommendation among adolescents across the U.S. regions has been limited. Therefore, the present study was conducted to determine if region was associated with provider recommendation of HPV vaccines in 2019-2021 and whether changes in recommendations varied by region. METHOD Using a cross-sectional design to examine National Immunization Survey-Teen (2019-2021) data, logistic regression and moderation analyses were performed to model region variation in HPV vaccine recommendations (n = 50,739 respondents). RESULTS The odds of recommendation were higher in the Midwest (aOR, 1.17 [95% CI, 1.06-1.29]), and Northeast (aOR, 1.38 [95% CI, 1.23-1.56]) regions than in the South region. Also, the odds of provider recommendation were higher in 2020 (aOR,1.16 [95% CI, 1.03-1.30]) than in 2019. Other variables-sex, age, race/ethnicity, health insurance status, and poverty status-were associated with recommendation of HPV vaccination. CONCLUSION Although the improvement in recommendation from 2019 to 2020 is an important public health gain, recommendation in the South still lags behind that in other regions. More efforts are needed to improve HPV vaccination recommendations in this region.

Abstract
The COVID-19 pandemic posed a major challenge in cancer care worldwide which might have an impact on the management of diffuse large B-cell lymphoma (DLBCL). We conducted a retrospective study comparing characteristics, management, and outcomes of DLBCL patients diagnosed during the first year of the COVID-19 pandemic (1/3/2020-28/2/2021) to those diagnosed in the previous year (1/3/2019-28/2/2020) in two tertiary centers in Italy and Israel. 182 patients were diagnosed with DLBCL during the study period. More patients were diagnosed during the pandemic compared to the year before: 60 vs. 29 and 54 vs. 39 in Italy and in Israel, respectively. Trends towards older age and higher transformation rates were shown during the pandemic. The interval between the initiation of symptoms and diagnosis was longer during the pandemic. Five and four patients were diagnosed with COVID-19 during treatment in Italy and in Israel, respectively. there was no difference in dose density and intensity of treatment, before and during the pandemic. The median follow-up during and before the pandemic was 15.2 and 25.5 months, respectively. Progression-free survival (PFS) was slightly shorter during the pandemic compared to the year before (64.9% vs. 70.6%; p = 0.0499). In multivariate analysis, older age and transformed disease were independently related to PFS, while diagnosis of DLBCL during the pandemic was not. Despite the challenges caused by COVID-19 pandemic, the management of DLBCL patients remained unchanged including dose density and intensity. Nevertheless, a shorter PFS during the outbreak might be attributed to differences in patients' characteristics.

Abstract
Persistent infection with high-risk types of human papillomaviruses (HPV) is a major cause of cervical cancer, and an important factor in other malignancies, for example, head and neck cancer. Despite recent progress in screening and vaccination, the incidence and mortality are still relatively high, especially in low-income countries. The mortality and financial burden associated with the treatment could be decreased if a simple, rapid, and inexpensive technology for HPV testing becomes available, targeting individuals for further monitoring with increased risk of developing cancer. Commercial HPV tests available in the market are often relatively expensive, time-consuming, and require sophisticated instrumentation, which limits their more widespread utilization. To address these challenges, novel technologies are being implemented also for HPV diagnostics that include for example, isothermal amplification techniques, lateral flow assays, CRISPR-Cas-based systems, as well as microfluidics, paperfluidics and lab-on-a-chip devices, ideal for point-of-care testing in decentralized settings. In this review, we first evaluate current commercial HPV tests, followed by a description of advanced technologies, explanation of their principles, critical evaluation of their strengths and weaknesses, and suggestions for their possible implementation into medical diagnostics.

Abstract
Women's health has been critically underserved by a failure to look beyond women's sexual and reproductive systems to adequately consider their broader health needs. In almost every country in the world, noncommunicable diseases are the leading causes of death for women. Among these, cardiovascular disease (including heart disease and stroke) and cancer are the major causes of mortality. Risks for these conditions exist at each stage of women's lives, but recognition of the unique needs of women for the prevention and management of noncommunicable diseases is relatively recent and still emerging. Once they are diagnosed, treatments for these diseases are often costly and noncurative. Therefore, we call for a strategic, innovative life-course approach to identifying disease triggers and instigating cost-effective measures to minimize exposure in a timely manner. Prohibitive barriers to implementing this holistic approach to women's health exist in both the social arena and the medical arena. Recognizing these impediments and implementing practical approaches to surmounting them is a rational approach to advancing health equity for women, with ultimate benefits for society as a whole.

Abstract
Human papillomavirus (HPV) is a common sexually transmitted infection that can cause both benign and malignant lesions. HPV vaccines, preferably administered before the onset of sexual activity, have demonstrated remarkable efficacy in preventing HPV-related cancers. The impact of a healthcare provider's recommendation on HPV vaccine acceptance is substantial. Therefore, medical students must undergo thorough training in this domain. This study compares fundamental understanding and viewpoints regarding HPV and anti-HPV vaccines among Polish students pursuing medical and non-medical sciences. This study was based on the authors' questionnaire, and the results were statistically analyzed. The participants in this study were 1025 students (medical sciences students-520 respondents in total; and non-medical sciences students-505 respondents in total). According to the results, medical students' knowledge about the consequences of HPV infection and vaccination against HPV was significantly greater. To date, numerous publications have investigated the understanding of particular social, gender, parental, etc., groups about vaccination, but the knowledge of students at different universities-medical and other-has not been compared. Social awareness is still insufficient, even in groups of medical students. There is much to be done to educate and encourage preventive behavior in those not receiving primary prevention in early childhood.

Abstract
Women with HSIL typically undergo conization/LEEP to remove cervical lesions, but the risk of HSIL lesions returning after surgical treatment remains higher than in the general population. HPV vaccination is essential to prevent cervical cancer. However, the effect of prophylactic HPV vaccination on reducing the risk of recurrent cervical lesions after surgical treatment remains unclear. This review aims to analyze and summarize the latest literature on the role of prophylactic HPV vaccine in reducing the recurrence of cervical lesions after surgery in patients with HSIL, and to review and update the history, efficacy, effectiveness and safety of HPV vaccine, focusing on the current status of global HPV vaccine implementation and obstacles.

Abstract
The COVID-19 pandemic has exacerbated the existing challenges to achieving the WHO target of eliminating cervical cancer as a public health problem by working towards the target of fewer than four cases per 100 000 women. We reviewed the literature to identify potential recovery strategies to support cervical cancer prevention programs in lower-and middle-income countries (LMICs) following COVID-19 disruptions and the extent to which strategies have been implemented. Utilising the WHO health systems framework, we mapped these recovery strategies against the six building blocks to examine their reach across the health system. Most recovery strategies were focused on service delivery, while leadership and governance played a pivotal role in the continuity of cervical cancer prevention programs during the pandemic. Leadership and governance were the drivers for outcomes in the building blocks of health information systems, financing and critical support in operationalising service delivery strategies. In the aftermath of the COVID-19 pandemic with strained health resources and economies, stakeholders would significantly influence the coverage and sustainability of cervical cancer prevention programs. The support from multisectoral stakeholders would accelerate the recovery of cervical cancer prevention programs. To achieve the WHO target by 2030, we call for future studies to understand the barriers and facilitators from the perspectives of stakeholders in order to support the decision-making processes and information required to implement recovery strategies in LMICs.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination among adolescents has steadily improved over the past several years. However, research conducted to determine whether the COVID-19 pandemic disrupted this positive trend in HPV vaccine initiation among racial and ethnic minority adolescents is limited. Therefore, this study was conducted to determine if the COVID-19 pandemic and the resulting changes in the US health-care sector affected the increasing HPV vaccine initiation among non-Hispanic Black and Hispanic adolescents aged 13-17 years. METHODS Using a cross-sectional design to examine data from the National Immunization Survey-Teen (2019-2021), logistic regression and moderation analysis were used to model race-specific variations in HPV vaccine initiation (n = 49 031). Two-sided P values of up to .05 were considered statistically significant. RESULTS Hispanic (adjusted odds ratio [AOR] = 1.35, 95% confidence interval [CI] = 1.16 to 1.57) and non-Hispanic Black (AOR = 1.29, 95% CI = 1.10 to 1.51) adolescents had higher odds of HPV vaccine initiation than did non-Hispanic White adolescents. Additionally, the odds of HPV vaccine initiation were higher in 2021 (AOR = 1.22, 95% CI = 1.08 to 1.38) than in 2019. Other variables-age, region, sex, insurance status, and poverty status-were also associated with HPV vaccine initiation. CONCLUSION These findings demonstrate that during the COVID-19 pandemic, racial and ethnic minorities had higher odds of receiving the HPV vaccine. Therefore, more research of the impact of the pandemic on HPV vaccine initiation among non-Hispanic White and racial and ethnic minority adolescents is needed.

Abstract
The COVID-19 pandemic disrupted healthcare delivery within safety-net settings. Barriers to and facilitators of human papillomavirus (HPV) vaccination during the pandemic can inform future HPV vaccine strategies for underserved communities. Qualitative interviews (n = 52) between December 2020 and January 2022 in Los Angeles and New Jersey were conducted with providers, clinic leaders, clinic staff, advocates, payers, and policy-level representatives involved in the HPV vaccine process. Using the updated Consolidated Framework for Implementation Research we identified (1) outer setting barriers (i.e., vaccine hesitancy driven by social media, political views during the pandemic) and facilitators (e.g., partnerships); (2) inner setting clinic facilitators (i.e., motivation-driven clinic metrics, patient outreach, vaccine outreach events); (3) individual characteristics such as patient barriers (i.e., less likely to utilize clinic services during the pandemic and therefore, additional outreach to address missed vaccine doses are needed); (4) innovations in HPV vaccination strategies (i.e., clinic workflow changes to minimize exposure to COVID-19, leveraging new community partnerships (e.g., with local schools)); and (5) implementation strategies (i.e., multisectoral commitment to HPV goals). Pandemic setbacks forced safety-net settings to develop new vaccine approaches and partnerships that may translate to new implementation strategies for HPV vaccination within local contexts and communities.

THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 37:100798. [PMID: 37359996 PMCID: PMC10285272 DOI: 10.1016/j.lanwpc.2023.100798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 03/09/2023] [Accepted: 05/07/2023] [Indexed: 06/28/2023]
Abstract
Background In 2008/9, Fiji vaccinated >30,000 girls aged 9-12 years with the quadrivalent human papillomavirus (4vHPV) vaccine coverage for at least one dose was >60% (one dose only was 14%, two dose only was 13%, three doses was 35%). We calculated vaccine effectiveness (VE) of one, two and three doses of 4vHPV against oncogenic HPV genotypes 16/18, eight years following vaccination. Methods A retrospective cohort study was undertaken (2015-2019) in pregnant women ≤23 years old, eligible to receive 4vHPV in 2008/9, with confirmed vaccination status. The study was restricted to pregnant women due to the cultural sensitivity of asking about sexual behavior in Fiji. For each participant a clinician collected a questionnaire, vaginal swab and genital warts examination, a median eight (range 6-11) years post vaccination. HPV DNA was detected by molecular methods. Adjusted VE (aVE) against the detection of vaccine HPV genotypes (16/18), the comparison group of non-vaccine genotypes (31/33/35/39/45/51/52/56/58/59/66/68), and genital warts were calculated. Covariates included in the adjusted model were: age, ethnicity and smoking, according to univariate association with any HPV detection. Findings Among 822 participants the prevalence of HPV 16/18 in the unvaccinated, one, two and three-dose groups were 13.3% (50/376), 2.5% (4/158), 0% (0/99) and 1.6% (3/189), respectively; and for the non-vaccine high-risk genotypes, the detection rate was similar across dosage groups (33.2%-40.4%, p = 0.321). The aVE against HPV 16/18 for one, two and three doses were 81% (95% CI; 48-93%), 100% (95% CI; 100-100%), and 89% (95% CI; 64-96%), respectively. Prevalence of HPV 16/18 was lower among women with longer time since vaccination. Interpretations A single dose 4vHPV vaccine is highly effective against HPV genotypes 16 and 18 eight years following vaccination. Our results provide the longest duration of protection for reduced dose 4vHPV schedule in a low- or middle-income country in the Western Pacific region. Funding This study was supported by the Bill & Melinda Gates Foundation and the Department of Foreign Affairs and Trade of the Australian Government and Fiji Health Sector Support Program (FHSSP).

Abstract
Human papillomavirus (HPV) is causally associated with 5% of cancers, including cancers of the cervix, penis, vulva, vagina, anus and oropharynx. The most carcinogenic HPV is HPV-16, which dominates the types causing cancer. There is also sufficient evidence that HPV types 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59 cause cervical cancer. The L1 protein, which, when assembled into virus-like particles, induces HPV-type-specific neutralising antibodies, forms the basis of all commercial HPV vaccines. There are six licensed prophylactic HPV vaccines: three bivalent, two quadrivalent and one nonavalent vaccine. The bivalent vaccines protect from HPV types 16 and 18, which are associated with more than 70% of cervical cancers. Prophylactic vaccination targets children before sexual debut, but there are now catch-up campaigns, which have also been shown to be beneficial in reducing HPV infection and disease. HPV vaccination of adults after treatment for cervical lesions or recurrent respiratory papillomatosis has impacted recurrence. Gender-neutral vaccination will improve herd immunity and prevent infection in men and women. HPV vaccines are immunogenic in people living with HIV, but more research is needed on the long-term impact of vaccination and to determine whether further boosters are required.

EClinicalMedicine 2023; 60:102038. [PMID: 37396806 PMCID: PMC10314142 DOI: 10.1016/j.eclinm.2023.102038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 05/19/2023] [Accepted: 05/22/2023] [Indexed: 07/04/2023] Open
Abstract
Background Carrageenan demonstrated potent anti-HPV (human papillomavirus) activity in vitro and in animal models. The Carrageenan-gel Against Transmission of Cervical Human papillomavirus trial's interim analysis (n = 277) demonstrated a 36% protective effect of carrageenan against incident HPV infections. Herein, we report the trial's final results. Methods In this exploratory phase IIB randomised, placebo-controlled trial, we recruited healthy women aged ≥18 years primarily from health service clinics at two Canadian Universities in Montreal. Participants were randomised (1:1) by the study coordinator (using computer-assisted block randomisation with randomly variable block sizes up to a block size of eight) to a carrageenan-based or placebo gel to be self-applied every other day for the first month and before/after intercourse. Participants, study nurses, and laboratory technicians (HPV testing and genotyping) were blinded to group assignment. At each visit (months 0, 0.5, 1, 3, 6, 9, 12), participants provided questionnaire data and a self-collected vaginal sample (tested for 36 HPV types, Linear Array). The primary outcome was type-specific HPV incidence (occurring at any follow-up visit). Intention-to-treat analyses for incidence were conducted using Cox proportional hazards regression models, including participants with ≥2 visits. Safety analyses included all participants randomised. This trial is registered with the ISRCTN registry, ISRCTN96104919. Findings Between Jan 16, 2013 and Sept 30, 2020, 461 participants (enrolled) were randomly assigned to the carrageenan (n = 227) or placebo (n = 234) groups. Incidence and safety analyses included 429 and 461 participants, respectively. We found 51.9% (108/208) of participants in carrageenan and 66.5% (147/221) in placebo arm acquired ≥1 HPV type (hazard ratio 0.63 [95% CI: 0.49-0.81], p = 0.0003). Adverse events were reported by 34.8% (79/227) and 39.7% (93/234) of participants in carrageenan and placebo arm (p = 0.27), respectively. Interpretation Consistent with the interim analysis, use of a carrageenan-based gel compared to placebo resulted in a 37% reduction in risk of incident genital HPV infections in women with no increase in adverse events. A carrageenan-based gel may complement HPV vaccination. Funding Canadian Institutes of Health Research, CarraShield Labs Inc.

Abstract
BACKGROUND Human Papilloma Virus (HPV) is the most common sexually transmitted infection worldwide. Globally, both men and women have a 50% risk of being infected at least once in their life. HPV prevalence is among the highest in sub-Saharan Africa (SSA), at an average of 24%. HPV causes different types of cancers, including cervical cancer (CC), which is the leading cause of cancer deaths among women in SSA. HPV-vaccination has been proven to be effective in reducing HPV induced cancers. SSA countries are delayed in reaching the WHO's target of fully vaccinating 90% of girls within the age of 15 by 2030. Our systematic review aims to identify barriers and facilitators of HPV-vaccination in SSA to inform national implementation strategies in the region. METHODS This is a mixed method systematic review based on the PRISMA statement and The Joanna Briggs Institute Reviewers' Manual. Search strategies were adapted to each selected database: PubMed/MEDLINE, Livivo, Google Scholar, Science Direct, and African Journals Online for papers published in English, Italian, German, French and Spanish between 1 December 2011 and 31 December 2021. Zotero and Rayyan were the software used for data management. The appraisal was conducted by three independent reviewers. RESULTS A total of 20 articles were selected for appraisal from an initial 536 articles. Barriers included: limited health system capacities, socio-economic status, stigma, fear and costs of vaccines, negative experience with vaccinations, COVID-19 pandemic, lack of correct information, health education (HE) and consent. Additionally, we found that boys are scarcely considered for HPV-vaccination by parents and stakeholders. Facilitators included: information and knowledge, policy implementation, positive experience with vaccinations, HE, stakeholders' engagement, women's empowerment, community engagement, seasonality, and target-oriented vaccination campaigns. CONCLUSIONS This review synthesizes barriers and facilitators of HPV-vaccinations in SSA. Addressing these can contribute to the implementation of more effective HPV immunization programs targeted at eliminating CC in line with the WHO 90/70/90 strategy.

Abstract
Low HPV vaccination rates among Latina young adults perpetuate HPV-associated cancer disparities. Using qualitative methods, this study explored individual, interpersonal, and community factors that influence HPV vaccine delay and refusal among Mexican- and U.S.-born Mexican American young adult women. Participants (N = 30) between 18 and 26 years old were purposively sampled from two federally qualified health centers in Orange County, California. The National Institute on Minority Health and Health Disparities research framework and narrative engagement theory guided semi-structured phone interviews coded inductively and deductively. Participants primarily attributed vaccine status to individual and interpersonal reasons. Emerging themes included low HPV vaccine knowledge, insufficient provider communication, negative perceptions about HPV and the vaccine, motherhood responsibilities, mother's communication about HPV, cultural family norms, health care access, and misinformation. Compared to U.S.-born Latinas, Mexican-born participants more frequently expressed avoiding health care discussions with family. HPV vaccine recommendations for young Mexican American women should include socioculturally tailored messages that may improve HPV vaccination acceptance and uptake.

Abstract
Introduction The COVID-19 pandemic disrupted the preventive services for cervical cancer (CC) control programs in Mexico, which will result in increased mortality. This study aims to assess the impact of the pandemic on the interruption of three preventive actions in the CC prevention program in Mexico. Methods This study is a retrospective time series analysis based on administrative records for the uninsured population served by the Mexican Ministry of Health. Patient data were retrieved from the outpatient service information system and the hospital discharge database for the period 2017-2021. Data were aggregated by month, distinguishing a pre-pandemic and a pandemic period, considering April 2020 as the start date of the pandemic. A Poisson time series analysis was used to model seasonal and secular trends. Five process indicators were selected to assess the disruption of the CC program, these were analyzed as monthly data (N=39 pre-pandemic, N=21 during the pandemic). HPV vaccination indicators (number of doses and coverage) and diagnostic characteristics of CC cases were analyzed descriptively. The time elapsed between diagnosis and treatment initiation in CC cases was modeled using restricted cubic splines from robust regression. Results Annual HPV vaccination coverage declined dramatically after 2019 and was almost null in 2021. The number of positive Papanicolaou smears decreased by 67.8% (90%CI: -72.3, -61.7) in April-December 2020, compared to their expected values without the pandemic. The immediate pandemic shock (April 2020) in the number of first-time and recurrent colposcopies was -80.5% (95%CI:-83.5, -77.0) and -77.9% (95%CI: -81.0, -74.4), respectively. An increasing trend was observed in the proportion of advanced stage and metastatic CC cases. The fraction of CC cases that did not receive medical treatment or surgery increased, as well as CC cases that received late treatment after diagnosis. Conclusions Our analyses show significant impact of the COVID-19 pandemic with declines at all levels of CC prevention and increasing inequalities. The restarting of the preventive programs against CC in Mexico offers an opportunity to put in place actions to reduce the disparities in the burden of disease between socioeconomic levels.

Abstract
To assess how the COVID-19 pandemic affected catch-up HPV vaccination among age-eligible adults (ages 18-45). The current study leverages a national, cross-sectional sample of US adults ages 18-45 years to assess the prevalence and determinants of COVID-19 pandemic-related disruptions to catch-up HPV vaccination in 2021. The sample was restricted to adults intending to receive the HPV vaccine. Multinomial logistic regression analysis was conducted to assess the probability of 1) pandemic-related HPV vaccination disruption and 2) uncertainty about pandemic-related HPV vaccination disruption. Report of 'no pandemic-related HPV vaccination disruption' served as the reference category. Among adults intending to get the HPV vaccine (n = 1,683), 8.6 % reported pandemic-related HPV vaccination disruption, 14.7 % reported uncertainty about vaccination disruption, and 76.7 % reported no disruption. Factors associated with higher odds of pandemic-related vaccination disruption included non-English language preference (OR: 3.20; 95 % CI: 1.99-5.13), being a parent/guardian (OR: 1.77; 95 % CI: 1.18-2.66), having at least one healthcare visit in the past year (OR: 1.97; 95 % CI: 1.10-3.53), being up-to-date on the tetanus vaccine (OR: 1.81; 95 % CI: 1.19-2.75), and being a cancer survivor (OR: 2.57; 95 % CI: 1.52-4.34). Catch-up HPV vaccination for age-eligible adults is a critical public health strategy for reducing HPV-related cancers. While a small percentage of adults reported pandemic-related disruptions to HPV vaccination, certain adults (e.g., individuals with a non-English language preference and cancer survivors) were more likely to report a disruption. Interventions may be needed that increase accessibility of catch-up HPV vaccination among populations with reduced healthcare access during the pandemic.

Abstract
Cervical cancer still poses a significant global challenge. Developed countries have mitigated this challenge by the introduction of structured screening programmes and, more recently, the HPV vaccine. Countries that have successfully introduced national HPV vaccination programmes are on course for cervical cancer elimination in a few decades. In developing countries that lack structured screening and HPV vaccination programmes, cervical cancer remains a major cause of morbidity and mortality. The HPV vaccine is key to addressing the disproportionate distribution of cervical cancer incidence, with much to be gained from increasing vaccine coverage and uptake globally. This review covers the history and science of the HPV vaccine, its efficacy, effectiveness and safety, and some of the considerations and challenges posed to the achievement of global HPV vaccination coverage and the consequent elimination of cervical cancer.

Abstract
INTRODUCTION Breast and cervical cancers represent two important causes of cancer-associated deaths in females. Uptake in prevention towards these cancers remains low in the United Arab Emirates. OBJECTIVES This study aimed to understand the knowledge, attitudes and practices of females residing in the Al Ain city, UAE, towards cervical and breast cancer prevention. METHODS This cross-sectional survey was conducted with 300 women, aged 30 years and above. The primary outcome measure was cervical and breast cancer prevention knowledge. The knowledge was queried through a number of items, with the resulting aggregate scores categorized into good and low knowledge. Chi-square test was conducted to investigate the association between prevention knowledge and sociodemographic factors. Additional outcomes included attitude towards and uptake of cervical and breast cancer screening. RESULTS Of the participants surveyed, 36.7% had good knowledge on breast cancer prevention, while 5.3% on cervical cancer prevention. Although the majority of the participants believed that prevention methods could save lives, they reported negative attitudes, considering screening unnecessary and painful. The self-reported screening uptake was 23% and 31.3% for mammography and Pap smear, respectively. CONCLUSIONS The study reported that the knowledge and uptake of women was low for both breast and cervical cancer prevention. Targeted campaigns not only to increase knowledge but also to resolve misconceptions to change negative attitudes may lead to an increase in uptake.

Abstract
Cervical cancer due to human papillomavirus (HPV) infection is a leading cause of mortality among women in low-resource settings. Many Sub-Saharan African countries have introduced HPV vaccination programs at the national level in the last few years. However, countries are struggling to maintain sustainable coverage. This study focuses on the introduction and sustainability challenges, context-specific key lessons learned, and mechanisms of action to achieve high sustainable coverage from low and lower-middle-income countries (LLMICs) that have introduced HPV vaccination programs by collating evidence from a literature review and key informant interviews. Local data availability was a challenge across countries, with the lack or absence of registries, data collection and reporting mechanisms. Multi-sectoral coordination and early involvement of key stakeholders were cited as an integral part of HPV programs and facilitators for sustainable coverage. Key informants identified periodic sensitization and training as critical due to high staff turnover. Health workforce mobilization was fundamental to ensure that the health workforce is aware of the disease etiology, eligibility requirements, and can dispel misinformation. Schools were reported to be an ideal sustainable platform for vaccination. However, this required teachers to be trained, which was often not considered in the programs. District-level staff were often poorly informed and lacked the technical and logistic capacity to support vaccination rounds and data collection. To improve the sustainability of HPV vaccination programs, there is a need for timely microplanning, efficient preparedness assessment, assessing training approaches, periodic training, finding innovative ways to achieve equity and adoption of a bottom-up approach to ensure that processes between districts and central level are well-connected and resources are distributed efficiently.

Abstract
It is unclear how the COVID-19 pandemic impacted human papillomavirus (HPV) vaccine uptake and which sociodemographic groups may have been most impacted. We aimed to assess differences in HPV vaccine uptake (initiation and completion) before and during the pandemic in the United States. We conducted a cross-sectional study using data from the 2019 to 2020 National Immunization Surveys - Teen (NIS-Teen), comparing vaccine initiation and completion rates in 2019 vs. 2020, based on confirmed reports by a healthcare provider. Weighted logistic regression analysis estimated odds of vaccine initiation and completion for both adolescent and parental characteristics. There were 18,788 adolescents in 2019 and 20,162 in 2020. There was 3.6% increase in HPV vaccine initiation (71.5% vs. 75.1%) and a 4.4% in completion (54.2% vs. 58.6%) rates from 2019 to 2020. In 2020, Non-Hispanic White teens were significantly less likely to initiate (aOR = 0.62, 95% CI: 0.49, 0.79) and complete (aOR = 0.71, 95% CI: 0.58, 0.86) vaccine uptake compared with non-Hispanic Black teens. Additionally, teens who lived above the poverty line were also less likely to initiate HPV vaccination (aOR = 0.63, 95% CI: 0.49, 0.80) or complete them (aOR = 0.73, 95% CI: 0.60, 0.90), compared to those who lived below the poverty line. During the COVID-19 pandemic in 2020, some historically advantaged socioeconomic groups such as those living above the poverty line were less likely to receive HPV vaccine. The impact of the pandemic on HPV vaccine uptake may transcend traditional access to care factors.

Abstract
Cervical cancer remains a leading cause of morbidity and mortality amongst females in Latin America (LATAM). Cervical cancer is a preventable disease and HPV vaccination is a main key strategy towards its elimination. This study analyzes HPV vaccine implementation current status and the main barriers to achieve adequate coverage in the region. Data from the nineteen sovereign states of LATAM (comprised of all Portuguese and Spanish-speaking nations located south of the United States) were collected, including year of HPV vaccine implementation, gender and age targets, the number of doses included in the public program and coverage by dose. Sixteen out of the 19 evaluated countries have already implemented HPV vaccination programs. However, despite its proven efficacy and safety, HPV vaccine uptake in LATAM has been lower than expected. There is an evident decline in adhesion, mainly regarding the second dose. Several reasons are probably involved, of note: limited knowledge of HPV and HPV vaccine, misguided safety concerns, high cost, cultural barriers, and the Covid19 pandemic. Proper strategies to overcome these barriers are needed to ensure successful uptake. Effective policies are: adopting the one dose schedule, delivering the vaccine on both health center and schools, and advising health professionals to recommend the vaccine. Further research regarding HPV vaccine hesitancy in Latin America is needed.

Single-dose HPV vaccine immunity: is there a role for non-neutralizing antibodies? Trends Immunol 2022; 43:815-825.

Abstract
A single dose of human papillomavirus (HPV) vaccine against HPV infection (prerequisite for cervical cancer) appears to be as efficacious as two or three doses, despite inducing lower antibody titers. Neutralizing antibodies are thought to be the primary mediator of protection, but the threshold for protection is unknown. Antibody functions beyond neutralization have not been explored for HPV vaccines. Here, we discuss the immune mechanisms of HPV vaccines, with a focus on non-neutralizing antibody effector functions. In the context of single-dose HPV vaccination where antibody is limiting, we propose that non-neutralizing antibody functions may contribute to preventing HPV infection. Understanding the immunological basis of protection for single-dose HPV vaccination will provide a rationale for implementing single-dose HPV vaccine regimens.

Abstract
Background: Each year 604,127 new cases of cervical cancer (CC) are diagnosed, and 341,831 individuals die from the disease. It is the fourth most common cancer among women and the fourth most common cause of death from female cancers worldwide. The pathogenesis of CC is associated with human papillomavirus (HPV) infections and consists of several steps involving cell proliferation outside the human body’s control mechanisms. Strategies to prevent CC are based on screening and vaccination. Scope of the Review: The aim of this paper was to collect and analyze the available literature on the issue of CC prevention and the impact of the COVID-19 pandemic on its implementation. For this purpose, PubMed and Google Scholar databases were searched using keywords, such as “cervical cancer”; “HPV”; “prevention”; “prophylaxis”; “vaccination”; “screening” and “COVID-19” in different variations. Only articles published since 2018 were included in the study. Conclusions: Selected European countries have different CC prevention programs funded by national budgets. This translates into observed differences in the risk of death from CC (age-standardized rate Malta = 1.1, Poland = 5.9). COVID-19 pandemic due to disruption of CC screening may exacerbate these differences in the future. To improve the situation, new screening methods, such as p16/Ki67, HPV self-testing, and the use of artificial intelligence in colposcopic assessment, should be disseminated, as well as free HPV vaccination programs implemented in all countries. The search for new solutions is not without significance and entails ultra-sensitive screening tests for risk groups (mRNA E6/E7, SOX1/SOX14), HPV vaccines with shorter dosing schedules, and new therapeutic pathways using nanotheranostics.

Abstract
PURPOSE OF REVIEW Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections worldwide and is a precursor to anogenital and oropharyngeal cancers. Effective prevention is available through HPV vaccination and emerging evidence demonstrates the potential to significantly impact HPV-associated disease through reductions in the incidence of genital warts, precancerous cervical lesions, and cervical cancer. Indications have also recently expanded to include the prevention of oropharyngeal cancer, an outcome that has been increasing in incidence for men and women. Yet despite demonstrated effectiveness, the potential for broader impact and well-established routine recommendations for administration to adolescents, barriers to vaccine uptake persist. The purpose of this review is to provide an update on HPV prevention in the US, including trends in disease burden, HPV vaccine effectiveness, evolving vaccine recommendations and opportunities and barriers to their implementation. RECENT FINDINGS Several studies have demonstrated that HPV vaccination has the potential to prevent most HPV-attributable cancers. Ongoing research addresses questions related to duration of protection, effectiveness in vulnerable populations, vaccine schedules and strategies to improve access and optimize uptake. SUMMARY To ensure continued impact on the prevention of HPV-associated disease and subsequent cancer, it is crucial to address gaps in vaccine uptake. A strong recommendation for all persons for whom HPV vaccines are indicated, alongside initiatives to increase awareness of HPV vaccination and address specific concerns, can improve uptake among hesitant populations. Globally, efforts to bolster immunization programs are needed to broaden access to HPV vaccination.

Abstract
OBJECTIVE To compare Australian Immunisation Register (AIR) human papillomavirus (HPV) vaccination coverage against historical data from the former National HPV Vaccination Program Register and estimate two-dose vaccination coverage. METHODS Cross-sectional analysis of registry data for adolescent birth cohorts (1998-2007). Denominator populations were Medicare enrolments (AIR) and ABS estimated resident populations (HPV register). RESULTS For adolescents aged <17 years, AIR coverage estimates were several percentage points lower than HPV register estimates due to a larger Medicare enrolment denominator. Completed course coverage (two or three valid doses) for 15-year-old females in 2020 was 81.5% and for males 78.6%, higher than completed course coverage in 15-year-olds in 2019 (79.7 and 76.8% respectively). First dose coverage was similar for Indigenous adolescents but course completion was lower, although improving over time. Course completion was slightly lower (3.5-5.7%) in areas of lowest socioeconomic status and greatest remoteness. CONCLUSIONS Coverage is slightly lower using AIR than HPV register estimates. Moving from three to two doses has slightly improved completion, likely due to the wider dose spacing, but equity gaps remain. IMPLICATIONS FOR PUBLIC HEALTH An ongoing focus on equity in vaccine delivery is needed. Systems, reminders and catch-up opportunities to ensure course completion remain important.

Abstract
INTRODUCTION Vaccines against human papillomavirus (HPV) are the key to controlling cervical cancer in low/middle-income countries (LMICs) where incidence is highest, but there have been limited data from these settings on programme impact on HPV prevalence, and none in a population with endemic HIV infection. Furthermore, for many LMICs, the currently recommended two-dose schedule is difficult to deliver at scale, so there is mounting interest in a single-dose schedule. METHODS AND ANALYSIS The Human Papillomavirus One and Two-Dose Population Effectiveness Study is a hybrid impact evaluation of the national South African HPV vaccination programme, which has targeted grade 4 girls aged at least 9 years in public schools with two doses of vaccine since 2014, and a single-dose vaccine 'catch-up' programme delivered in one district in 2019. Impacts of both schedules on the prevalence of type-specific HPV infection will be measured using repeat cross-sectional surveys in adolescent girls and young women aged 17-18 years recruited at primary healthcare clinics in the four provinces. A baseline survey in 2019 measured HPV prevalence in the cohort who were ineligible for vaccination because they were already above the target age or grade under either the national programme or the single-dose programme in the selected district. HPV prevalence surveys are repeated in 2021 in the selected district, and in 2023 in all four provinces. We will calculate prevalence ratios to compare the prevalence of HPV types 16 and 18 in the single-dose (2021) and two-dose (2023) cohorts, with the vaccine-ineligible (2019) cohort. ETHICS AND DISSEMINATION The project was approved by the University of the Witwatersrand Human Research Ethics Committee (HREC #181005), and the University of New South Wales HREC (#181-005). Findings will be disseminated through peer-reviewed journals, scientific meetings, reports and community forums.

Human Papillomavirus Vaccination in South Africa: Programmatic Challenges and Opportunities for Integration With Other Adolescent Health Services? Front Public Health 2022; 10:799984. [PMID: 35174123 PMCID: PMC8841655 DOI: 10.3389/fpubh.2022.799984] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 01/07/2022] [Indexed: 12/17/2022] Open
Abstract
Compared to other regions of the world, sub-Saharan Africa has made limited progress in the implementation and performance of nationwide human papillomavirus (HPV) vaccination programmes. Without urgent intervention, this will serve to undermine cervical cancer elimination efforts in this region. The primary intent of this narrative review is to highlight the programmatic successes and challenges of the school-based HPV vaccination programme in South Africa since its inception in 2014, with the aim of contributing to the evidence base needed to accelerate implementation and improve programme performance in other sub-Saharan African countries. As of 2020, the proportion of adolescent girls aged 15 years who had received at least one dose of the HPV vaccine at any time between ages 9–14 years was 75%, while 61% had completed the full recommended two-dose schedule. This gives some indication of the reach of the South African HPV vaccination programme over the past 6 years. Despite this, vaccine coverage and dose completion rates have persistently followed a downward trend, slowing progress toward attaining global elimination targets. There is evidence suggesting that declining public demand for the HPV vaccine may be a result of weakening social mobilization over time, inadequate reminder and tracking systems, and vaccine hesitancy. Another concern is the disproportionate burden of HPV and HIV co-infections among adolescent girls and young women in South Africa, which predisposes them to early development of invasive cervical cancer. Moving forward, national policy makers and implementers will have to explore reforms to current age eligibility criteria and vaccine dose schedules, as well as implement strategies to support vaccine uptake among populations like out-of-school girls, girls attending private schools, and HIV positive young women. Additional opportunities to strengthen the South African HPV vaccination programme can be achieved by scaling up the co-delivery of other adolescent health services such as comprehensive sexual and reproductive health and rights education, deworming, and health screening. This calls for reinforcing implementation of the integrated school health policy and leveraging existing adolescent health programmes and initiatives in South Africa. Ultimately, establishing tailored, adolescent-centered, integrated health programmes will require guidance from further operational research.

Abstract
BACKGROUND Cervical cancer, caused by human papillomavirus infection, is the source of significant personal and societal burden, and robs more than one hundred thousand Indian women and their families of the chances of a healthy and productive life each year. As outlined by the World Health Organization, the three-pronged approach of screening, vaccination, and reduction in mortality by early treatment presents the possibility of the elimination of cervical cancer as a public health problem in the next decade.1 Unfortunately, these approaches are all associated with significant barriers in India. OBJECTIVES Given that the main mandate of palliative care practitioners to prevent and relieve suffering, here we make the case for these practitioners to offer education around vaccination and screening to female relatives of women encountered with cervical cancer. CONCLUSION Offering prevention strategies for human papillomavirus aligns with the idea of preventing suffering and is within the scope of palliative care clinicians.

Abstract
OBJECTIVE The COVID-19 pandemic has led to significant reductions in the administration of routinely recommended vaccines among adolescents in the US including tetanus, diphtheria, and acellular pertussis (Tdap); meningococcal (ACWY); and human papillomavirus (HPV) vaccines. The extent to which these deficits could persist in 2021 and beyond is unclear. To address this knowledge gap, this study estimated the cumulative deficits of routine vaccine doses among US adolescents during the COVID-19 pandemic and estimated the time and effort needed to recover from those deficits. METHODS Monthly reductions in Tdap, meningococcal, and HPV doses administered to US adolescents during the COVID-19 pandemic were quantified using MarketScan Commercial Claims and Encounters data. The time and effort required to reverse the vaccination deficit under various catch-up scenarios were estimated. RESULTS Annual doses administered of Tdap, meningococcus, and HPV vaccines decreased by 21.2%, 20.8%, and 24.0%, respectively, in 2020 compared to 2019. For 2021, the reduction in doses administered is projected to be 6%-21% compared to 2019 under different scenarios. The projected deficit of missed doses is expected to be cleared between winter 2023 and fall 2031. CONCLUSIONS Administration rates of routine vaccines decreased significantly among US adolescents during COVID-19. Reversing these deficits to mitigate long-term health and economic consequences will require a sustained increase in vaccination rates over multiple years.

A Review of the Implementation Status of and National Plans on HPV Vaccination in 17 Middle-Income Countries of the WHO Western Pacific Region. Vaccines (Basel) 2021; 9:vaccines9111355. [PMID: 34835286 PMCID: PMC8626009 DOI: 10.3390/vaccines9111355] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/12/2021] [Accepted: 11/15/2021] [Indexed: 11/17/2022] Open
Abstract
The World Health Organization’s Western Pacific Region is responsible for one-fourth of the global cervical cancer burden, and nearly 90% of that burden is concentrated in middle-income countries (MICs). Applying a conceptual model of implementation of population-based interventions, we synthesized the current implementation status of human papillomavirus (HPV) vaccination and national plans that form the basis of its implementation in 17 MICs. We gathered information from a range of governmental documents, published studies, and global databases. For all available national cancer-related plans and immunization plans, we examined the description of HPV vaccination. We found that, as of July 2021, only four countries (24%) had a mature HPV vaccination program with a high first-dose coverage; three (18%) had introduced HPV vaccination, but needed further efforts to scale it up, seven (41%) had not been able to introduce it after conducting demonstration projects, and three (18%) did not have any experience in HPV vaccination. In the national plans, most of the countries recognized the importance of HPV vaccination, but only 10 (59%) provided an implementation strategy on how it would be introduced or scaled up. Countries with a mature program were more likely to have their implementation strategy detailed in their national cancer control plan. Successful implementation of HPV vaccination requires overcoming known challenges and having a clear national plan. Positioning HPV vaccination clearly in the overall national cancer control plan may be key to accelerating its nationwide implementation.

Abstract
Human papillomaviruses (HPV) cause a subset of head and neck cancers (HNSCC). HPV16 predominantly signs responsible for approximately 10% of all HNSCC and over 50% of tonsillar (T)SCCs. Prevalence rates depend on several factors, such as the geographical region where patients live, possibly due to different social and sexual habits. Smoking plays an important role, with non-smoking patients being mostly HPV-positive and smokers being mostly HPV-negative. This is of unparalleled clinical relevance, as the outcome of (non-smoking) HPV-positive patients is significantly better, albeit with standard and not with de-escalated therapies. The results of the first prospective de-escalation studies have dampened hopes that similar superior survival can be achieved with de-escalated therapy. In this context, it is important to note that the inclusion of p16INK4A (a surrogate marker for HPV-positivity) in the 8th TMN-classification has only prognostic, not therapeutic, intent. To avoid misclassification, highest precision in determining HPV-status is of utmost importance. Whenever possible, PCR-based methods, still referred to as the "gold standard”, should be used. New diagnostic antibodies represent some hope, e.g., to detect primaries and recurrences early. Prophylactic HPV vaccination should lead to a decline in HPV-driven HNSCC as well. This review discusses the above aspects in detail.
