Iseme-Ondiek R, Abuodha J, Ngugi A, Abayo I, Saleh M. Insights Into Cancer Awareness and Health Practices in Rural Kenya: A Cross-Sectional Study of Esophageal, Breast, Prostate, Cervical, and Colorectal Cancers. JCO Glob Oncol 2025; 11:e2400421. [PMID: 40344548 DOI: 10.1200/go-24-00421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2024] [Revised: 03/14/2025] [Accepted: 04/01/2025] [Indexed: 05/11/2025] Open
Abstract
PURPOSE In sub-Saharan Africa (SSA), there has been an epidemiologic transition from infectious diseases to noncommunicable diseases, including a projected doubling in incidence of cancer. Understanding the underlying factors driving this surge is crucial for designing effective strategies to mitigate the cancer burden. This study focuses on assessing knowledge, attitudes, screening practices, and health behaviors related to five most prevalent cancers in SSA: prostate, breast, cervical, esophageal, and colorectal-among a predominantly rural coastal population in Kenya. MATERIALS AND METHODS We used a cross-sectional study design targeting 1,500 adult respondents randomly selected from an existing community health and demographic surveillance system. Face-to-face interviewer-administered questionnaires were used to collect data. RESULTS One thousand four hundred fifty-two adults participated in the final survey. Breast cancer awareness was highest (69.1%), while awareness of colorectal cancer was lowest (34.6%). Given a list of possible risk factors and symptoms, most respondents (>50%) could only recognize one to two per cancer type. Perceptions of survival from colorectal cancer were particularly pessimistic, with <70% recognizing early detection as a means to improve survival outcomes. In terms of cancer-associated risk factors, more men engaged in tobacco and alcohol use (20.5% and 22.4%, respectively). Additionally, fewer than 10% of eligible participants had ever undergone cancer screening. CONCLUSION This study addresses a gap in population-level Knowledge, Attitudes, and Practices studies in rural SSA, offering insights crucial for cancer prevention, early detection, and treatment. The low awareness and knowledge levels and unhealthy behaviors emphasize a need for targeted educational campaigns at community level and enhanced understanding of barriers to uptake of screening if we are to effectively combat the growing cancer burden in this region.

Abstract
Human papillomavirus (HPV) is a widespread and diverse group of viruses that are responsible for various clinical conditions, including cervical cancer, one of the most common cancers among women worldwide. In Africa, the prevalence and distribution of HPV genotypes vary significantly across different regions. In this study, we analyzed the genetic diversity, geographical distribution, and evolutionary dynamics of HPV genotypes across various African countries to provide insights into the prevalence and transmission patterns of HPV. A total of 9203 genome sequences of HPV isolates from cervical samples from 21 African countries were obtained from the GenBank database. Of these, 184 were identified as unique sequences and were used for further analysis. Phylogenetic analysis demonstrated that the African HPV sequences share genetic ancestry with European sequences, whereas American isolates are less closely related. Migration analysis revealed a significant asymmetry in HPV flow, with migration rates from Africa to Europe consistently exceeding those in the opposite direction, suggesting that Africa is a major source of HPV genetic variants entering Europe. This interconnectedness underscores the intricate interplay of historical, regional, and cultural determinants that have collectively contributed to shaping the genomic landscape of African strains. The geographically variable HPV genotypes 35, 31, 16, 18, 58, 45, 7, and 66 are the most common in Africa. Algeria, Morocco, Rwanda, and Guinea have diverse genotypes, and the rates of infection are highest in the Republic of Congo and Chad.

Papillomavirus Vaccination Programs and Knowledge Gaps as Barriers to Implementation: A Systematic Review. Vaccines (Basel) 2025; 13:460. [PMID: 40432072 PMCID: PMC12116001 DOI: 10.3390/vaccines13050460] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2025] [Revised: 04/23/2025] [Accepted: 04/24/2025] [Indexed: 05/29/2025] Open
Abstract
BACKGROUND/OBJECTIVES Human papillomavirus (HPV) is a leading cause of cervical cancer. Despite the proven effectiveness of vaccination programs, global coverage remains uneven, with significant disparities across regions due to various socioeconomic, cultural, and political factors. This study explores the primary barriers to HPV vaccination worldwide and proposes recommendations to improve access to screening and vaccination programs. METHODS A systematic literature review was conducted, analyzing studies published in the past ten years from databases such as PubMed, Scopus, and Embase, following the PRISMA methodology. Study selection involved multiple researchers, with discrepancies resolved through consultation. The quality of the included studies was assessed using CASP checklists. The protocol was registered on Open Science Framework (OSF). RESULTS Out of 2119 records, eight studies were included. The findings indicate that the main barriers to HPV vaccination include insufficient public awareness, cultural and religious resistance, financial constraints, and limited access in rural and underserved areas. Additionally, political factors, such as low prioritization of HPV vaccination and the absence of supportive policies, were identified as significant obstacles. Multidisciplinary and cross-cultural collaboration, along with the integration of HPV vaccination into existing health programs, was suggested as a strategic approach to improve vaccine uptake. CONCLUSIONS Barriers to HPV vaccination, including limited awareness, inadequate healthcare infrastructure, and socioeconomic factors, vary across regions but must be addressed to improve global coverage. Targeted interventions such as health education, inclusive policies, and culturally sensitive campaigns can significantly boost vaccine uptake. Strengthening local health systems and fostering international collaboration are key strategies to overcoming these barriers and ensuring equitable access to HPV vaccination.

Haddison EC, Engoung DB, Bodo CB, Njie VM. Overcoming HPV vaccine hesitancy: insights from a successful school-based vaccination campaign in the Saa health district of Cameroon. BMC Infect Dis 2025; 25:465. [PMID: 40186125 PMCID: PMC11971776 DOI: 10.1186/s12879-025-10864-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2025] [Accepted: 03/28/2025] [Indexed: 04/07/2025] Open
Abstract
BACKGROUND Vaccination against human papillomavirus (HPV) represents a critical strategy in the global effort to eradicate cervical cancer. Nonetheless, the uptake of HPV vaccination in Cameroon has been slow, resulting in vaccine wastage during a period of constrained global supply. In the Saa health district, factors such as concerns about infertility, fears of COVID-19 infection, and restrictions on HPV awareness initiatives in Catholic churches and schools have been identified as contributors to vaccine hesitancy. This report outlines the observations from a successful impromptu HPV vaccination campaign conducted in the context of this hesitancy within the Saa health district. METHODS The campaign took place from the 9th to 25th of May 2023 and targeted 853 adolescents aged 9-13 years. A single-dose schedule with Gardasil was used mainly through the school strategy. Community health workers, teachers and priests participated in sensitization activities via door-to-door sensitization for parents, sensitization in schools for students and in churches for faithfuls respectively. Health facilities vaccinated schools in their catchment area. Vaccination data were recorded in routine vaccination registers. RESULTS A total of 1321 adolescents (154%) were vaccinated, 48.9% (n = 646) of whom were boys. Thirty-four primary and two secondary schools participated in the campaign. Health workers, teachers and Catholic priests all participated in sensitization activities. No backlash was reported from parents after vaccination. CONCLUSION The successful execution of the campaign can be attributed to the active involvement of key stakeholders within the health district. Continuous advocacy for HPV vaccination, even in a climate of vaccine hesitancy, plays a significant role in positively altering perceptions. Recognizing stakeholders and their influence is essential for tailoring strategies aimed at enhancing HPV vaccine uptake.

Health Policy Plan 2025; 40:23-30. [PMID: 38955674 PMCID: PMC11724633 DOI: 10.1093/heapol/czae059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 06/17/2024] [Accepted: 07/01/2024] [Indexed: 07/04/2024] Open
Abstract
New vaccine policy adoption is a complex process, especially in low-and-middle-income countries, requiring country policymakers to navigate challenges such as competing priorities, human and financial resource constraints, and limited logistical capacity. Since the beginning of the Expanded Programme on Immunization, most new vaccine introductions under this structure have not been aimed at adult populations. The majority of adult vaccines offered under the Expanded Programme on Immunization are not typically tested among and tailored for pregnant persons, except those that are specifically recommended for pregnancy. Given that new maternal vaccines, including respiratory syncytial virus and group B streptococcus vaccines, are on the horizon, it is important to understand what barriers may arise during the policy development and vaccine introduction process. In this study, we sought to understand information needs among maternal immunization policymakers and decision-makers in Kenya for new vaccine maternal policy adoption through in-depth interviews with 20 participants in Nakuru and Mombasa, counties in Kenya. Results were mapped to an adapted version of an established framework focused on new vaccine introduction in low-and-middle-income countries. Participants reported that the policy process for new maternal vaccine introduction requires substantial evidence as well as coordination among diverse stakeholders. Importantly, our findings suggest that the process for new maternal vaccines does not end with the adoption of a new policy, as intended recipients and various actors can determine the success of a vaccine programme. Previous shortcomings, in Kenya, and globally during human papillomavirus vaccine introduction, show the need to allocate adequate resources in education of communities given the sensitive target group. With maternal vaccines targeting a sensitive group-pregnant persons-in the pipeline, it is an opportune time to understand how to ensure successful vaccine introduction with optimal acceptance and uptake, while also addressing vaccine hesitancy to increase population benefit.

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
BACKGROUND The World Health Organization recommends a single-dose human papillomavirus (HPV) vaccination schedule for girls and boys to accelerate progress toward cervical cancer elimination. We applied the Theoretical Framework of Acceptability (TFA) within the context of HPV vaccination to assess the acceptability of a single-dose schedule among health-care professionals in Kenya. METHODS A REDCap survey was developed using relevant Theoretical Framework of Acceptability domains and validated with health-care professionals. Descriptive analyses and multivariate Poisson regression were conducted to assess factors associated with increased acceptability. Free-text responses were analyzed using a rapid qualitative approach, and findings were presented using a joint display. RESULTS Among 385 responses, 74.2% of health-care professionals were female and 48.6% were nurses. On average, respondents had been in their position for 60 months, and one-third (33.2%) were based at level-4 facilities. The majority (75.84%) thought that giving a single-dose of the HPV vaccine to adolescent girls and young women was either acceptable or very acceptable. Qualitative findings highlighted that lack of information was the underlying reason for health-care professionals who were resistant, and most clinicians thought that a singled-dose schedule was less burdensome to clinicians and patients. Hospital directors had a non-statistically significantly lower acceptability likelihood than nurses (incident rate ratio = 0.93, 95% confidence interval = 0.45 to 1.71) and health-care professionals at urban facilities had a non-statistically significantly lower acceptability likelihood than clinicians in rural facilities (incident rate ratio = 0.97, 95% confidence interval = 0.83 to 1.13). CONCLUSION Although not statistically significant, predictors of increased acceptability provide information to tailor strategies to increase HPV vaccination coverage and accelerate progress toward cervical cancer elimination.

The Potential Impact of a Single-Dose HPV Vaccination Schedule on Cervical Cancer Outcomes in Kenya: A Mathematical Modelling and Health Economic Analysis. Vaccines (Basel) 2024; 12:1248. [PMID: 39591151 PMCID: PMC11598770 DOI: 10.3390/vaccines12111248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2024] [Revised: 10/27/2024] [Accepted: 10/28/2024] [Indexed: 11/28/2024] Open
Abstract
Background: Human Papillomavirus (HPV) is the primary cause of cervical cancer. Single-dose HPV vaccination can effectively prevent high-risk HPV infection that causes cervical cancer and accelerate progress toward achieving cervical cancer elimination goals. We modelled the potential impact of adopting single-dose HPV vaccination strategies on health and economic outcomes in Kenya, where a two-dose schedule is the current standard. Methods: Using a validated compartmental transmission model of HPV and HIV in Kenya, we evaluated the costs from the payer's perspective to vaccinate girls by age 10 with either one or two doses and increasing coverage levels (0%, 70%, 77%, 90%). Additionally, we modelled single-dose strategies supplemented with either catch-up vaccination of adolescent girls and young women or vaccination for all by age 10, funded with the first five-years of cost savings of switching from a two- to one-dose schedule. Costs and outcomes were discounted at 3% annually, and incremental cost-effectiveness ratios (ICERs) were calculated per disability-adjusted-life-year (DALY) averted. Results: All one-dose and the two-dose 90% coverage strategies were on the efficiency frontier, dominating the remaining two-dose strategies. The two-dose 90% coverage strategy had a substantially higher ICER (US$6508.80/DALY averted) than the one-dose 90% coverage (US$197.44/DALY averted). Transitioning from a two- to one-dose schedule could result in US$21.4 Million saved over the first five years, which could potentially fund 2.75 million supplemental HPV vaccinations. With this re-investment, all two-dose HPV vaccination scenarios would be dominated. The greatest DALYs were averted with the single-dose HPV vaccination schedule at 90% coverage supplemented with catch-up for 11-24-year-old girls, which had an ICER of US$78.73/DALYs averted. Conclusions: Considering the logistical and cost burdens of a two-dose schedule, a one-dose schedule for girls by age 10 would generate savings that could be leveraged for catch-up vaccination for older girls and accelerate cervical cancer elimination in Kenya.

Abstract
Human papillomavirus (HPV) coinfection remains common globally. However, its clinical significance compared to mono-infection remains controversial. Further, the epidemiology of HPV genotype combination in coinfection is not well studied in Kenya. . Between June and August 2023, a cross-sectional facility-based survey enrolled 434 women aged 16-68 years using purposive sampling strategy. Structured questionnaire was obtained from each woman regarding demographic and sexual behavior characteristics. Cervical specimen was collected from each participant and analyzed using RIATOL assay to determine HPV genotypes and viral load. Overall, HPV 52 was the most frequently detected HPV strain. The mean HPV viral load was elevated among coinfected women than those with mono-infection but there was no evidence to support differences in viral load in the two groups (P = 0.113). Mono-infection was common (58.52%). HPV 16 was noted to have a near equal presence both in mono-infection and coinfection (52.17% and 47. 83%), respectively. HPV 33 (alpha 9) and 45 (alpha 7) had the greatest preference for each other compared to all other HPV interactions. HPV 52 is the most prevalent HPV in the population supporting the need for the nonavalent HPV vaccine. Mono-infection with HPV 16 remains common corroborating the relevance of bivalent vaccine in resource limited setting where nonavalent vaccines may be unavailable. The frequent coinfection preference of HPV 33 and 45 (alpha 9 and alpha 7, respectively) pauses the need for further concurrent characterization. HPV vaccination and education on safe sexual behaviors is key in reducing HPV coinfection.

Abstract
BACKGROUND Persistent human papillomavirus (HPV) infection is considered the primary etiological factor for invasive cervical cancer. Understanding the epidemiology of circulating potential high-risk (HR) and HR HPV strains is essential in updating epidemiological knowledge and recommendations on genotype-specific vaccination development. This study determined the prevalence and factors associated with Potential HR/HR HPV among women attending selected reproductive health clinics in Lake Victoria Basin. METHODS A cross-sectional facility-based survey made up of 434 women aged 16-68 years was carried out in two selected facilities. Structured questionnaires were administered to collect participant clinical and social characteristics. Cervical specimens were collected and HPV genotyping was carried out using RIATOL HPV genotyping qPCR assay. Descriptive statistics followed by logistic binary regression was done using R version 4.3.2. RESULTS The overall prevalence of potential HR/HR HPV among women attending the selected reproductive health clinics was reported at 36.5% (158/434). Specifically, in the rural setting, Gobei Health Center, the prevalence was 41.4% (41/99) while in the urban setting-JOOTRH, it was 34.6% (117/335). The most prevalent potential HR/HR HPV are 52, 67, 16, 31, 39, 45, and 31 among women. Age was the main factor associated with HPV infection with women between the age of 30-39 having the highest risk (AOR = 0.3, CI:0.2-0.7, p < 0.001). CONCLUSION In both rural and urban regions, potential HR/HR HPV infection among women attending reproductive health clinics at the selected facilities remains common. The study identifies the need for effective implementation and clinical follow-up process of cervical cancer control program in the LVB.

Abstract
Introduction Human papillomavirus (HPV) causes cervical cancer, and HPV vaccination is highly effective in preventing vaccine-targeted HPV infection. However, low HPV vaccination coverage in Kisumu County, Kenya, at about 10% for the first dose, highlights the critical issue of vaccine hesitancy, particularly in low and middle-income countries. Methods This study explores the concerns, myths and barriers to HPV vaccine uptake among adolescent girls (aged 10-14) enrolled at human immune-deficiency virus comprehensive care clinics and their parents in Kisumu County. Focused group discussions were conducted with 48 participants. Results Content analysis revealed limited knowledge about the HPV vaccine and widespread misconceptions regarding its safety and efficacy. Financial constraints, injection fears and negative clinic experiences emerged as additional barriers. Conclusion The findings emphasise the role of effective communication strategies, including engaging parents through written materials and involving them in decision-making, to dispel myths, provide accurate information and encourage HPV vaccination. Collaborative efforts with community stakeholders are crucial to improve vaccine coverage and ultimately reduce the cervical cancer burden.

Abstract
Background Influenza is a significant contributor to acute respiratory infections (ARI), and children < 5 years are at increased risk of severe influenza disease. In Kenya the influenza vaccine is not included in the Kenya Expanded Programme on Immunization (KEPI). To inform roll-out of a national influenza vaccination program, we implemented an influenza vaccine demonstration project in Nakuru and Mombasa counties in Kenya from 2019 to 2021 and set out to establish factors driving influenza vaccine acceptance and hesitancy among caregivers of children aged 6-23 months. Methods Using semi-structured questionnaires, we conducted eight focus group discussions among community members and twelve key informant interviews among healthcare workers to elicit both lay and expert opinions. Thematic analysis of the interviews was conducted using the World Health Organization's "3 Cs" model of vaccine hesitancy to determine reasons for acceptance or hesitancy of the influenza vaccine. Results The influenza vaccine was well received among community members and healthcare workers though concerns were raised. Vaccine hesitancy was fuelled by misconceptions about reasons for introducing the vaccine (confidence), perceptions that influenza was not a serious disease (complacency) and administrative fees required at some facilities (convenience). Despite the use of various advocacy, communication and social mobilisation strategies targeted at educating the community on the influenza disease and importance of vaccination, there remained a perception of inadequate reach of the sensitization among some community members. Contextual factors such as the COVID-19 pandemic affected uptake, and parents expressed concern over the growing number of vaccines recommended for children. Conclusion Despite lingering concerns, caregivers had their children vaccinated indicating that vaccine hesitancy exists, even among those who accepted the vaccine for their children. Efforts targeted at increasing confidence in and reducing misconceptions towards vaccines through effective communication strategies, are likely to lead to increased vaccine uptake.

Abstract
Introduction cervical cancer is a significant health challenge in Kenya and sub-Saharan Africa, with high mortality linked to late presentation and low awareness. Despite its prevalence, preventive interventions like human papillomavirus (HPV) vaccination face low utilization. Religious leaders play a pivotal role in influencing health decisions, yet their attitudes toward HPV vaccination remain understudied. Therefore, this study aims to determine religious leaders' willingness to promote HPV vaccine uptake in Mavoko Sub-County, Machakos County, Kenya. Methods a cross-sectional study involving 198 religious leaders chosen through systematic random sampling method was done in the month of December 2023 in Machakos County, Kenya. Data on socio-demographics and attitudes towards HPV vaccination were collected using structured, self-administered questionnaires. Attitudes were gauged on 11 statements. Analysis was performed using IBM SPSS 22.0, employing descriptive statistics and Chi-square tests to assess associations, with significance set at p < 0.05. Results were visually presented using tables, charts and graphs. Results the study had a 96.6% response rate. Majority were male (51.5%), Protestant Christians (48%), and pastors (29.8%). Most participants had positive attitudes towards the HPV vaccine, with no significant socio-demographic associations found. Conclusion the study reveals positive attitudes among religious leaders towards promoting HPV vaccine uptake among their congregants. Despite some concerns and misconceptions, the majority of participants expressed willingness to advocate for vaccination.

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

Abstract
Health care workers play an essential role in maintaining the public trust in vaccination programmes globally, and more specifically, in low- and middle-income countries. This role is particularly important in building trust in the human papillomavirus (HPV) vaccine. While there are many factors that affect HPV vaccine acceptance, health care workers are one of the most critical influences in the decision-making process among parents as well as adolescent girls. In this paper, we sought to better understand how health care workers in a diverse set of countries communicate and promote HPV vaccines. We summarize communication approaches and lessons learned by health care workers in Kenya, India, and Nigeria through a case study approach. In Kenya, the utilization of a multisectoral approach proved to be very important. In India, intense social mobilization with targeted messaging by target audience laid the groundwork for community acceptance. An evolving communication strategy was essential in Nigeria, where there is no national HPV vaccination programme. Given the increase in vaccine hesitancy globally, the lessons learned through these three country examples highlight the importance of communication efforts in increasing vaccine acceptance.

Abstract
The human papillomavirus (HPV) vaccine is effective in cervical cancer prevention. However, many barriers to uptake exist and strategies to overcome them are needed. Therefore, this study aimed to select and tailor implementation strategies to barriers identified by multiple stakeholders in Zambia. The study was conducted in Lusaka district between January and February 2023. Participants were purposively sampled from three stakeholder groups namely, adolescent girls, parents, and teachers and healthcare workers. With each of the stakeholders' groups (10-13 participants per group), we used the nominal group technique to gain consensus to tailor feasible and acceptable implementation strategies for mitigating the identified contextual barriers. The identified barriers included low levels of knowledge and awareness about the HPV vaccine, being out of school, poor community sensitisation, lack of parental consent to vaccinate daughters, and myths and misinformation about the HPV vaccine. The lack of knowledge and awareness of the HPV vaccine was a common barrier across the three groups. Tailored strategies included conducting educational meetings and consensus-building meetings, using mass media, changing service sites, re-examining implementation, and involving patients/consumers and their relatives. Our study contributes to the available evidence on the process of selecting and tailoring implementation strategies to overcome contextual barriers. Policymakers should consider these tailored strategies to mitigate barriers and improve HPV vaccine uptake.

Abstract
INTRODUCTION Morocco has joined the global efforts to eliminate cervical cancer by introducing human papillomavirus (HPV) vaccination into its national immunization program. However, vaccination rates remain insufficient relative to the importance of the vaccine. Therefore, the objective of the study was to understand better the factors associated with acceptance, hesitance, or refusal of the HPV vaccine. MATERIALS AND METHODS A descriptive and analytical study was conducted among 450 parents of girls of HPV vaccination age at the Mohammed VI University Hospital Center in Oujda, Morocco, over a period of three months. RESULTS A total of 450 parents were included in the study, most of them being mothers. Most parents were unaware of HPV infection (66%) or the HPV vaccine (62%). The rate of HPV vaccination among the study population was only 33%. Factors associated with nonvaccination included a lack of information about the HPV vaccine (57%), concern about side effects (33%), and unvaccinated family and friends (10%). Parents' intention to vaccinate their daughters was significantly lower in fathers (95% confidence interval, or 95% CI = 0.34-0.66), those with a low educational level (odds ratio, or OR = 0.53; 95% CI = 0.40-0.80), and those with an unfavorable socioeconomic level (OR = 0.41; 95% CI = 0.30-0.56), whereas it was significantly higher in cases of a vaccinated entourage, including friends and family (OR = 1.52; 95% CI = 1.22-2.12), and when vaccination was recommended by a doctor (OR = 1.92; 95% CI = 1.56-2.39). CONCLUSION The results of our study highlighted parents' lack of information about HPV infection and the HPV vaccine. They also revealed a clear lack of HPV vaccination coverage and identified the reasons for reluctance to vaccinate against HPV. Much remains to be done to increase the rate of HPV vaccination in Morocco.

Uptake of human papilloma virus vaccine and its determinants among females in East Africa: a systematic review and meta-analysis. BMC Public Health 2024; 24:842. [PMID: 38500046 PMCID: PMC10949808 DOI: 10.1186/s12889-024-18141-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 02/17/2024] [Indexed: 03/20/2024] Open
Abstract
INTRODUCTION Cervical cancer is the most common malignant tumor among women. It is the main cause of death among women in sub-Saharan African countries. Particularly, the incidence and mortality rates are highest in East Africa. Even though the burden of human papilloma virus-related cervical cancer is high in East Africa, there is no conclusive evidence about the prevalence of human papilloma virus vaccine uptake and its predictors. OBJECTIVE To assess the pooled prevalence of human papilloma virus vaccine uptake and its determinants in East Africa. METHOD Eligible articles were searched on PubMed, Embase, Scopus, Cochrane Library, Google Scholar, and Google. Those articles incorporating the outcome of interest, both analytical and descriptive study designs, and published or unpublished articles at any time were included. Keywords and Medical Subjects Heading terms or synonyms of human papilloma virus vaccine and Boolean operators were used to retrieve the articles. To assure the quality of articles, Joana Brigg's Institute critical appraisal checklist for cross-sectional studies was used. Sensitivity analysis was conducted to assess the heterogeneity among the studies, and a random effect model was used to analyze the pooled effect size. RESULT A total of 29 articles were included, and the pooled prevalence of HPV vaccine uptake in East Africa was 35% (95% CI: 26-45%). Good knowledge (OR = 1.6, 95%CI; 1.43-1.8), positive attitude (OR = 2.54, 95% CI; 2.13-3.03), ever heard about HPV vaccine (OR = 1.41, 95% CI; 1.03-1.94), mother educational status above college (OR = 1.84, 95%CI; 1.03-3.31), middle wealth index (OR = 1.33, 95%CI; 1.04-1.7), ≥ 9 family size (OR = 0.76, 95%CI; 0.68-0.98), availability of promotion (OR = 2.53, 95%CI: 1.51-4.26), availability of adequate vaccine (OR = 4.84, 95%CI; 2.9-8.08), outreach vaccination practice (OR = 1.47, 95%CI; 1.02-2.12) and family support (OR = 4.3, 95% CI; 2.98-6.21) were the significant factors for the uptake of human papilloma virus vaccine. CONCLUSION As compared to the global strategic plan, the pooled prevalence of HPV vaccine uptake in east Africa was low. The uptake of the HPV vaccine was higher among adolescents than youths. Knowledge about the HPV vaccine, attitude towards the HPV vaccine, ever hearing about the HPV vaccine, residence, mother's educational status, mother's occupational status, wealth index, and family size were the significant determinants of HPV vaccine uptake. Therefore, we recommend focusing on awareness creation and behavioral change to expand the uptake of vaccines in East Africa.

Abstract
Introduction Although the burden of cervical cancer in Africa is highest, HPV vaccination coverage remains alarmingly low in this region. Providers' knowledge and recommendation are key drivers of HPV vaccination uptake. Yet, evidence about providers' knowledge and recommendation practices about the HPV vaccine against a backdrop of emerging vaccine hesitancy fueled by the COVID-19 pandemic is lacking in Africa. Methods A cross-sectional study was conducted in 2021-2022 among healthcare providers involved in cervical cancer prevention activities in Africa. They were invited to report prior training, the availability of the HPV vaccine in their practice, whether they recommended the HPV vaccine, and, if not, the reasons for not recommending it. Their knowledge about the HPV vaccine was assessed through self-reporting (perceived knowledge) and with three pre-tested knowledge questions (measured knowledge). Results Of the 153 providers from 23 African countries who responded to the survey (mean age: 38.5 years, SD: 10.1), 75 (54.0%) were female and 97 (63.4%) were based In countries with national HPV immunization programs. Overall, 57 (43.8%) reported having received prior training on HPV vaccine education/counseling, and 40 (37.4%) indicated that the HPV vaccine was available at the facility where they work. Most respondents (109, 83.2%) reported recommending the HPV vaccine in their practice. Vaccine unavailability (57.1%), lack of effective communication tools and informational material (28.6%), and need for adequate training (28.6%) were the most commonly reported reasons for not recommending the HPV vaccine. While 63 providers (52.9%) reported that their knowledge about HPV vaccination was adequate for their practice, only 9.9% responded correctly to the 3 knowledge questions. Conclusion To increase HPV vaccination coverage and counter misinformation about this vaccine in Africa, adequate training of providers and culturally appropriate educational materials are needed to improve their knowledge of the HPV vaccine and to facilitate effective communication with their patients and the community.

Abstract
Despite prevalent preventative methods of human papillomavirus (HPV), cervical cancer remains the foremost cause of cancer-related death among women of reproductive age in Western Kenya. HPV self-sampling is a preventative measure that can improve accessibility and availability to cervical cancer screening. Correct education about HPV is crucial to combating stigma and increasing HPV screening uptake. In this study, we evaluated the workflow impact of a video-assisted HPV education to promote self-sampling in clinical settings in Kisumu, Kenya. We conducted a descriptive workflow study nested in a two-part cluster-randomized control trial in six government-supported health clinics in Kisumu County. We observed the workflow of HPV screening video-assisted and standard health educations. and evaluated community and clinic health assistant facilitation (CCHA), duration, and feasibility of the intervention. Thirty HPV screening-eligible women who participated in the video intervention were recruited for three focus group discussions (FGDs). The FGDs aimed to better understand women's experience with the video screening, their impressions on the content, and feedback about intervention logistics. Across 33 observations, 16.5 women per day watched the educational video at intervention clinics, and 14 women per day heard standard Ministry of Health cervical cancer prevention education talks at control clinics. Sixty-three percent of women participated in HPV self-sampling in the intervention sites, compared to forty-six percent who screened after standard health talks at control sites. The workflow observations identified variable video projection and viewing space, access to power supply, and CCHA availability and ability to utilize the projector as major factors impacting education workflow. Women in FGDs appreciated the video modality, length of video, and education location. HPV video education is a suitable intervention, with further research recommended to determine the viability of sustainably implementing the intervention in a clinic environment. This research is fully funded by the Duke University Global Health Institute.

The Acceptability of Pharmacy-Based HPV Vaccination in Western Kenya among Pharmacy Clients and Providers. Vaccines (Basel) 2023; 11:1808. [PMID: 38140211 PMCID: PMC10747628 DOI: 10.3390/vaccines11121808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 11/21/2023] [Accepted: 11/29/2023] [Indexed: 12/24/2023] Open
Abstract
Vaccine coverage for the human papillomavirus (HPV) remains low globally, and differentiated models of vaccine delivery are needed to expand access. Pharmacy-based models of the HPV vaccination may engage women who could benefit. We assessed the acceptability of such a model among pharmacy clients and providers at 20 private pharmacies in Kisumu County, Kenya. In questionnaires, participants (≥18 years) were asked the extent they agreed (5-point scale) with statements that assessed different acceptability component constructs outlined in the Theoretical Framework of Acceptability (TFA). From March to June 2022, 1500 pharmacy clients and 40 providers were enrolled and completed questionnaires. Most clients liked the intervention (TFA: affective attitude; 96%, 1435/1500) and did not think it would be hard to obtain (TFA: burden; 93%, 1399/1500). All providers agreed the intervention could reduce HPV infection (TFA: perceived effectiveness) and felt confident they could deliver it (TFA: self-efficacy). Among the clients who had received or were planning to receive the HPV vaccine in the future, half (50%, 178/358) preferred a pharmacy-based HPV vaccination. In this study, most Kenyan pharmacy clients and providers perceived a pharmacy-delivered HPV vaccination as highly acceptable; however, more research is needed to test the feasibility and effectiveness of this novel vaccine delivery model in Africa.

Abstract
Background The coronavirus 2019 (COVID-19) pandemic has caused disruptions in the delivery and utilisation of cancer services. The impact of these interruptions is disproportionately borne by low- and middle-income countries in Sub-Saharan Africa (SSA). There are speculations of increased late-stage presentation and mortality as services are returning to the pre-pandemic state. This review aims to explore the extent to which the COVID-19 pandemic impacted cancer services across SSA and to identify innovations implemented across SSA to mitigate the impacts. Methods Using database-specific search strategies, a systematic literature search was conducted in PubMed, Ovid (MedLine), Web of Science, and African Index Medicus. Eligible studies included original research, reports, perspectives and summaries of national or regional outcomes published in the English language. The primary outcome was changes in the delivery and utilisation of cancer prevention and screening, diagnosis, treatment and follow-up services. The secondary outcome was to identify implemented innovations to mitigate the impact of the pandemic on service delivery. Results Out of the 167 articles identified in the literature search, 46 were included in the synthesis. A majority (95.7%) of the included articles described suspension and/or delay of screening, diagnosis, and treatment services, although two studies (4.3%) described the continuation of services despite the lockdown. Care was additionally impacted by transportation limitations, shortages of staff and personal protective equipment, disruption of the medication supply chain and patients' fears and stigma associated with contracting COVID-19. A major innovation was the use of telemedicine and virtual platforms for patient consultation and follow-up during the pandemic in SSA. Furthermore, drones and mobile applications were used for sample collection, medication delivery and scheduling of treatment. In some instances, medication routes and treatment protocols were changed. Conclusions The delivery and utilisation of cancer services decreased substantially during the pandemic. Cancer centres initiated innovative methods of care delivery, including telehealth and drone use, with long-term potential to mitigate the impact of the pandemic on service delivery. Cancer centres in SSA must explore sustainable, facility or country-specific innovations as services return to the pre-pandemic state. Registration The review was registered in PROSPERO with registration number CRD42022351455.

Abstract
Background High-risk human papillomavirus (HR-HPV) is the primary cause of cervical cancer, leading to over 311 000 global deaths, mainly in low- and middle-income countries. Kenyan women living with HIV (WLHIV) face a disproportionate burden of HR-HPV. Objectives We determined the prevalence of HR-HPV infections and their association with cervical cytology findings among Kenyan WLHIV. Method We conducted a cross-sectional study among WLHIV attending the HIV care and treatment clinic at the Kenyatta National Hospital (KNH), Kenya's national referral hospital. Study nurses collected a cervical sample with a cytobrush for HR-HPV genotyping using Gene Xpert® assays and HPV Genotypes 14 Real-TM Quant V67-100FRT. Bivariate analysis explored the associations. Results We enrolled 647 WLHIV (mean age of 42.8 years), with 97.2% on antiretroviral therapy (ART) and 79% with a suppressed viral load (< 50 copies/mL plasma). The prevalence of any and vaccine-preventable HR-HPV was 34.6% and 29.4%, respectively, with HPV 52 being the most common genotype (13.4%). Among WLHIV with HR-HPV infections, 21.4% had abnormal cervical cytology. Women with multiple HR-HPV infections were more likely to have abnormal cytology compared to those with single HR-HPV infections (34.9 vs 9.3%, adjusted odds ratio [aOR] = 6.2, 95% confidence interval [CI]: 2.7-14.1, P = 0.001). Women with HR-HPV infection (single or multiple) were more likely to be on the second-line ART regimen compared to those without HR-HPV infections (53.1% vs 46.7%, aOR = 2.3, 95% CI: 1.3-4.1, P = 0.005). Conclusion Among WLHIV at KNH, abnormal cytology was common and more frequent among women with multiple HR-HPV infections.

Abstract
INTRODUCTION Despite the global vaccination campaign to prevent HPV-related morbidity, HPV vaccination uptake remains unacceptably low in the developing world, like Ethiopia. For strong interventional measures, compiled data in the field is required which is otherwise missed in the Ethiopian context. Therefore, this systematic review aimed to provide an estimate of the HPV vaccination uptake, mothers' willingness to vaccinate their adolescent girls, and associated factors in Ethiopia. METHODS Articles were systematically searched using comprehensive search strings from PubMed/Medline, SCOPUS, and grey literature from Google Scholar. Two reviewers assessed study eligibility, extracted data, and assessed the risk of bias independently. Meta-analysis was performed using STATA v 14 to pool the vaccination uptake and mothers' willingness toward HPV vaccination in Ethiopia. RESULTS We included 10 articles published between 2019 and 2022 covering reports of 3,388 adolescent girls and 2,741 parents. All the included articles had good methodological quality. The pooled estimate of the proportion of good knowledge about HPV vaccination and the agreement of girls to get the vaccine was 60% (95%CI: 59-62) and 65% (95%CI: 64-67), respectively. The pooled estimate of vaccination uptake of at least one dose of HPV vaccine among girls was 55% (95%CI: 53-57). Positive attitudes to the vaccine, higher maternal education, and having knowledge about HPV and its vaccine were reported as statistically significant predictors. On the contrary, not having adequate information about the vaccine and concerns about possible side effects were reported as reasons to reject the vaccine. Likewise, the pooled estimate of mothers who were knowledgeable about HPV vaccination, who had a positive attitude, and willing to vaccinate their children were 38% (95%CI: 36-40) 58% (95%CI: 56-60), and 74% (95%CI: 72-75), respectively. CONCLUSIONS Knowledge about the HPV vaccine among girls and their vaccination uptake is suboptimal that falls short of the 2030 WHO targets. Therefore, stakeholders need major efforts in rolling out vaccination programs and monitoring their uptake. Social mobilization towards primary prevention of HPV infection should focus on adolescents. The existing strategies need to address the predictors of uptake by educating girls and parents.

Abstract
Cervical cancer incidence continues to rise in Ghana. To enhance knowledge and prevention of cervical cancer among young people in Ghana, there is a need to better understand their education preferences. The study aimed to describe female senior school students' preferences for receiving cervical cancer education. A cross-sectional survey of students from 17 schools in the Ashanti Region of Ghana assessed the strength of preference for receiving cervical cancer education from a range of sources, settings and delivery mediums. Of the 2400 participants (aged 16-24 years), the majority endorsed doctors (87%, 95%CI: 85-88%), nurses (80%, 95%CI: 78-82%) and credible health organisations (78%, 95%CI%: 76-79%) as their preferred source of education, and hospitals 83% (95%CI: 81-84%) as the preferred setting. Nearly all students (92%) endorsed at least three cervical cancer education delivery mediums, with at least three quarters endorsing television (78%, 95%CI: 77-80%), one-on-one health consultation in-person or online (77%, 95%CI: 75-79%; 75%, 95%CI: 73-77%), and health information websites (75%, 95%CI: 73-77%). Findings suggest that cervical cancer education efforts among female senior school students in Ghana should consider the use of a range of more resource-intensive individualised approaches to low-cost anonymous, generic approaches from credible sources and institutions.

Abstract
OBJECTIVE To assess the uptake of human papillomavirus (HPV) vaccination and its associated factors among adolescents in Gambella town, Southwest Ethiopia. DESIGN A community-based cross-sectional study. SETTING Gambella town, Southwest Ethiopia. PARTICIPANTS A total of 882 adolescents were included between May and July 2022. OUTCOME Uptake of HPV vaccination. METHODS A cluster sampling technique was used to select study participants. An interviewer-administered and pretested questionnaire was used to collect the data. The collected data were entered into Epi-data V.4.6 and exported to STATA V.16 for cleaning, coding and analysis. A binary logistic regression model was used to test the association between independent and dependent variables. Variables with a p<0.05 in the multivariable logistic regression were considered statistically significant factors for the uptake of HPV vaccination. RESULTS A total of 825 adolescents participated in this study. Among participants, 48% (95% CI 44.6% to 51.4%) have been vaccinated for HPV. Ever heard of the HPV vaccine (AOR 2.5, 95% CI 1.23 to 5.08), good knowledge of HPV infection (AOR 3.62, 95% CI 2.17 to 6.02), good knowledge of the HPV vaccine (AOR 5.54, 95% CI 3.28 to 9.36) and attitude towards the HPV vaccine (AOR 2.74, 95% CI 1.88 to 3.98) were significantly associated HPV vaccination. CONCLUSION In the current study, the uptake of HPV vaccination was found to be low. The finding highlights the importance of promoting community health education about HPV infection and vaccines and providing behaviour change education, which plays a substantial role in promoting the uptake of HPV vaccination.

Abstract
Background Cervical cancer is the leading cause of cancer-related deaths among Kenyan women. Persistent infection with high-risk oncogenic Human papillomavirus (HPV) genotypes is a necessary cause of cervical cancer. HPV vaccines are safe, durable, and efficacious in preventing incident HPV infections. In Kenya, despite efforts to increase HPV vaccination, coverage remains low. We sought to assess: (1) barriers and facilitators of HPV vaccination from the perspective of adolescent girls and young women (AGYW), their guardians as well as stakeholders involved in HPV vaccine delivery, and (2) the acceptability of the single dose of the HPV vaccination among healthcare providers (HCPs). Methods Our study is nested within the KENya Single-dose HPV-vaccine Efficacy study (KEN SHE) that sought to test the efficacy of single-dose bivalent (HPV 16/18) and single-dose nonavalent (HPV 16/18/31/33/45/52/58/6/11) vaccination. We are conducting this study in Kiambu, Nairobi, and Kisumu counties. In these counties, we are interviewing stakeholders (n = ∼25), selected based on their role in HPV vaccination at the county and national levels. Interviews are audio recorded and conducted in English or Swahili. The semi-structured interview guides were designed based on: (1) the Theoretical Domains Framework (TDF) for AGYW and guardians and (2) the Consolidated Framework for Implementation Research (CFIR) for other stakeholders. The Theoretical Framework of Acceptability (TFA) was leveraged to design the survey administered to HCPs (n = ∼309) involved in HPV vaccination. We will develop a codebook based on emerging codes from the transcripts and constructs from the TDF and CFIR. Emerging themes will be summarized highlighting similarities and differences between and within the different stakeholder groups and counties. Descriptive statistics and a χ2 test will be used to assess the distribution of responses between the different sites and regression analysis will be used to assess factors associated with high acceptability of the single-dose strategy while controlling for confounding variables. Discussion Our study will describe key barriers and facilitators that affect HPV vaccination from the perspective of multiple stakeholders as well as insights on the perspective of HCPs towards the single-dose strategy to inform the designing of strategies to increase HPV vaccination uptake in Kenya and comparable settings.

Essoh TA, Adeyanju GC, Adamu AA, Tall H, Aplogan A, Tabu C. Exploring the factors contributing to low vaccination uptake for nationally recommended routine childhood and adolescent vaccines in Kenya. BMC Public Health 2023; 23:912. [PMID: 37208649 DOI: 10.1186/s12889-023-15855-w] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Accepted: 05/09/2023] [Indexed: 05/21/2023] Open
Abstract
BACKGROUND Vaccination remains the most effective means of reducing the burden of infectious disease among children. It is estimated to prevent between two to three million child deaths annually. However, despite being a successful intervention, basic vaccination coverage remains below the target. About 20 million infants are either under or not fully vaccinated, most of whom are in Sub-Saharan Africa region. In Kenya, the coverage is even lower at 83% than the global average of 86%. The objective of this study is to explore the factors that contribute to low demand or vaccine hesitancy for childhood and adolescent vaccines in Kenya. METHODS The study used qualitative research design. Key Informant Interviews (KII) was used to obtain information from national and county-level key stakeholders. In-depth Interviews (IDI) was done to collect opinions of caregivers of children 0-23 months and adolescent girls eligible for immunization, and Human papillomavirus (HPV) vaccine respectively. The data was collected at the national level and counties such as Kilifi, Turkana, Nairobi and Kitui. The data was analyzed using thematic content approach. A total of 41 national and county-level immunization officials and caregivers formed the sample. RESULTS Insufficient knowledge about vaccines, vaccine supply issues, frequent healthcare worker's industrial action, poverty, religious beliefs, inadequate vaccination campaigns, distance to vaccination centers, were identified as factors driving low demand or vaccine hesitancy against routine childhood immunization. While factors driving low uptake of the newly introduced HPV vaccine were reported to include misinformation about the vaccine, rumors that the vaccine is a form of female contraception, the suspicion that the vaccine is free and available only to girls, poor knowledge of cervical cancer and benefits of HPV vaccine. CONCLUSIONS Rural community sensitization on both routine childhood immunization and HPV vaccine should be key activities post COVID-19 pandemic. Likewise, the use of mainstream and social media outreaches, and vaccine champions could help reduce vaccine hesitancy. The findings are invaluable for informing design of context-specific interventions by national and county-level immunization stakeholders. Further studies on the relationship between attitude towards new vaccines and connection to vaccine hesitancy is necessary.

Abstract
Human papillomavirus (HPV) is a viral infection that, if does not go away, can cause health problems like genital warts and cancer. The national immunization schedules for individuals before sexual debut, significantly decreased HPV-associated mortality and it will be affordable. However, immunization programs remain vulnerable to macroeconomic factors such as inflation, fiscal policy, employment levels, and national income. This review aims to investigate the association between national income in lower-middle-income countries to explore recent advances and potential issues, as well as how to deal with challenges.

Abstract
Sub-Saharan Africa has the highest rates of cervical cancer in the world, largely attributed to low cervical cancer screening coverage. Cervical cancer is the most common cause of death among women in 21 of the 48 countries in sub-Saharan Africa. Close to 100% of all cases of cervical cancer are attributable to Human papillomavirus (HPV). HPV types 16 and 18 cause at least 70% of all cervical cancers globally, while types 31, 33, 45, 52, and 58 cause a further 20% of the cases. Women living with HIV are six times more likely to develop cervical cancer than those without HIV. Considering that sub-Saharan Africa carries the greatest burden of cervical cancer, ways to increase accessibility and use of preventive services are urgently required. With this review, we discuss the preventive measures required to reduce the burden of cervical cancer in sub-Saharan Africa, the challenges to improving accessibility and use of the preventive services, and the recommendations to address these challenges.

Abstract
BACKGROUND The human papillomavirus vaccine is one of the main preventative measures for cervical cancer. However, global vaccine uptake is low; the problem is particularly acute in low and middle-income countries. The purpose of this study is to assess female preparatory school students' knowledge, attitude, and uptake of the human papillomavirus vaccine and associated factors in Bahir Dar City, Ethiopia. METHODS Institutional-based cross-sectional study was conducted among 633 female preparatory school students in Bahir Dar city from March 1-30, 2021. Participants were selected using the multistage sampling technique. Data were collected using a structured self-administered questionnaire and entered into Epi-data and exported to SPSS for analysis. Binary and multivariable logistic regression analyses were done using an odds ratio with a 95% confidence interval. Finally-value < 0.05 was considered significant in multivariable analysis. RESULT The proportion of Human Papillomavirus (HPV) vaccine uptake, knowledge of the vaccine, and respondents' attitudes toward the vaccine were 45.3% (95% CI = 41.6-49.4%), 58.1% (95% CI = 54.4-61.9%), and 16% (95% CI = 13.2-19.5%), respectively. Having a history of sexual contact AOR = 2.80 (95% CI = 1.64-4.76), hearing about HPV infection AOR = 1.59 (95% CI = 1.13-2.24), and having a positive attitude toward HPV vaccine AOR = 1.46 (95% CI = 1.03-2.08) were significantly associated with knowledge about the HPV vaccine. Discussion of reproductive health issues with family AOR = 2.558 (95%CI = 1.800-3.636), and having good knowledge about HPV vaccine AOR = 3.571(95%CI = 2.494-5.113) were associated with a positive attitude toward the HPV vaccine. Good knowledge AOR = 2.36(95%CI = 1.48-3.76) and a positive attitude toward HPV vaccine AOR = 2.87(95%CI = 1.70-4.85) were strongly associated with HPV vaccine utilization. CONCLUSION In this study, there was a very low uptake of HPV vaccination among female students, and only a small proportion of them had good knowledge of the HPV vaccine and a favorable attitude toward the HPV vaccine.

Abstract
Cervical cancer can be prevented by human papillomavirus (HPV) vaccination. However, parents can have concerns about vaccinating their daughters. Consequently, there is a need to identify prevalence and risk factors for HPV vaccine hesitancy among parents in Kenya. A descriptive cross-sectional study was conducted among parents with children aged 9−14 years attending a leading referral hospital in Kenya. Data on sociodemographic traits, HPV knowledge, beliefs and vaccine hesitancy were collected. Out of 195 participants, 183 (93.5%) were aged >30 years. Thirty-four (46.4%) of males and 39 (35.1%) of females did not know that the vaccine is given to prevent HPV infection. Encouragingly, levels of vaccine acceptance were high (90%) although one-third (37.9%) had a negative perception about the effectiveness of the vaccine, with vaccine hesitancy attributed to safety concerns (76%) and feelings that the child was too young (48%). Positive beliefs and knowledge of the vaccine were positively associated with parental willingness to vaccinate their children. Low levels of parenteral education and a younger age among mothers were negatively associated with willingness to vaccinate. Most parents (59%) would consult their daughters before vaccination, and 77% (n = 150) recommended early sex education. Despite low knowledge levels, there was high parental willingness to have their children vaccinated.
