Abstract
AIM To assess community awareness, knowledge and perception of the malaria vaccine. DESIGN A descriptive cross-sectional survey. METHODS Multistage sampling was adopted in recruiting 400 participants. A structured questionnaire designed based on study objectives guided data collection. RESULTS Participants were 18-47 years with a mean age of 30 years. A statistically significant association was observed between socio-demographic characteristics (age, marital status, religion, education) and the awareness of the malaria vaccine. Majority of the participants (n = 190, 86.4%) said the vaccine was for the protection of children and they perceived that the vaccine would improve children's ability to fight diseases (n = 158, 71.8%), hence should be administered to every child (n = 201, 91.4%). Nurses and other health workers should intensify public education on the malaria vaccine. PATIENT OR PUBLIC CONTRIBUTION Caregivers of children in Kassena-Nankana East Municipality.

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
Background Vaccination is a fundamental tenet of public and population health. Several barriers to vaccine uptake exist, exacerbated post-COVID-19, including misconceptions about vaccine efficacy and safety, vaccine hesitancy, vaccine inequity, costs, religious beliefs, and insufficient education and guidance for healthcare professionals. Vaccine uptake may be aided using microarray patches (MAPs) due to reduced pain, no hypodermic needle, enhanced thermostability, and potential for self and lay administration. Objectives This protocol outlines the development of a scale that aims to accurately measure the perceived safety, usability, and acceptability of MAPs for vaccination among laypeople, MAP recipients, clinicians, and parents or guardians of children. Methods and analysis This study will follow three phases of scale development and validation, including (1) item development, (2) scale development, and (3) scale evaluation. Inductive (interviews) and deductive methods (literature searches) will be used to develop scale items, which experts from target populations will assess through an online survey. Cognitive interviews will be conducted to observe their processes of answering the draft survey. Thematic analysis will be conducted to analyse qualitative data. Lastly, four surveys will be administered online to our target populations over two time points to determine their repeatability. Exploratory and confirmatory factor analyses, Cronbach's alpha, and construct validity will be performed. Ethics This study was approved by Metro South Health (HREC/2021/QMS/81653) and Western Sydney Local Health District (2023/ETH00705) Human Research Ethics Committees. Discussion The scale will support a standardised approach to assessing the social and behavioural aspects of MAP vaccines, enabling comparison of outcomes across studies. Once validated, this scale will assist vaccination programmes in developing effective strategies for integrating MAPs and overcoming barriers to vaccination. This includes improving vaccine equity and accessibility, especially in lower- and middle-income countries and rural or remote locations.

Abstract
Achieving WHO cervical cancer elimination goals will necessitate efforts to increase HPV vaccine access and coverage in low-and-middle-income countries (LMICs). Although LMICs account for the majority of cervical cancer cases globally, scale-up of HPV vaccine programs and progress toward coverage targets in LMICs has been largely insufficient. Understanding the barriers and facilitators that stakeholders face in the introduction and scale-up of HPV vaccination programs will be pivotal in ensuring that LMICs are equipped to optimize the implementation of HPV vaccination programs. This qualitative study interviewed 13 global stakeholders categorized as either academic partners or global immunization partners to ascertain perspectives regarding factors affecting the introduction and scale-up of HPV vaccination programs in LMICs. Global stakeholders were selected as their perspectives have not been as readily highlighted within the literature despite their key role in HPV vaccination programming. The results of this investigation identified upstream (e.g., financial considerations, vaccine prioritization, global supply, capacity and delivery, and vaccine accessibility, equity, and ethics) and downstream (e.g., vaccine acceptability and hesitancy, communications, advocacy, and social mobilization) determinants that impact program introduction and scale-up and confirmed that strong political commitment and governance are significant in garnering support for HPV vaccines. As LMICs introduce HPV vaccines into their national immunization programs and develop plans for scaling up vaccination efforts, strategic approaches to communications and advocacy will also be needed to successfully meet coverage targets.

Abstract
BACKGROUND Microarray patches (MAPs) deliver vaccines to the epidermis and the upper dermis, where abundant immune cells reside. There are several potential benefits to using MAPs, including reduced sharps risk, thermostability, no need for reconstitution, tolerability and self-administration. We aimed to explore and evaluate the immunogenicity, safety, usability and acceptability of MAPs for vaccination. METHODS We searched CINAHL, Cochrane Library, Ovid Embase, Ovid MEDLINE and Web of Science from inception to January 2023. Eligibility criteria included all research studies in any language, which examined microarrays or microneedles intended or used for vaccination and explored immunogenicity, safety, usability or acceptability in their findings. Two reviewers conducted title and abstract screening, full-text reviewing and data extraction. RESULTS Twenty-two studies were included (quantitative=15, qualitative=2 and mixed methods=5). The risk of bias was mostly low, with two studies at high risk of bias. Four clinical trials were included, three using influenza antigens and one with Japanese encephalitis delivered by MAP. A meta-analysis indicated similar or higher immunogenicity in influenza MAPs compared with needle and syringe (N&S) (standardised mean difference=10.80, 95% CI: 3.51 to 18.08, p<0.00001). There were no significant differences in immune cell function between MAPs and N&S. No serious adverse events were reported in MAPs. Erythema was more common after MAP application than N&S but was brief and well tolerated. Lower pain scores were usually reported after MAP application than N&S. Most studies found MAPs easy to use and highly acceptable among healthcare professionals, laypeople and parents. CONCLUSION MAPs for vaccination were safe and well tolerated and evoked similar or enhanced immunogenicity than N&S, but further research is needed. Vaccine uptake may be increased using MAPs due to less pain, enhanced thermostability, layperson and self-administration. MAPs could benefit at-risk groups and low and middle-income countries.

Abstract
Introduction The human papillomavirus (HPV) vaccination is an important preventive measure for HPV-related conditions such as cervical cancer. In 2019, Zambia introduced a free national HPV vaccination program for 14-year-old girls. However, the adolescents' knowledge and perceptions regarding the HPV vaccine are not well understood. Therefore, this study aimed to understand adolescent girls' knowledge and perceptions regarding the HPV vaccine and discuss its acceptability and uptake implications. Methods We conducted a qualitative study in the Lusaka district between June 2021 and November 2021 using semi-structured interviews with adolescent girls aged 15-18 years regardless of their HPV vaccination status. Interviews were transcribed verbatim, and NVIVO 12 was used for data management and analysis. We coded transcripts deductively and inductively based on emerging themes. Perceptions were coded using the health belief model constructs. Results We interviewed 30 adolescent girls to reach saturation. Seventeen girls reported having received at least one dose of the HPV vaccine. Participants expressed variable knowledge and awareness about HPV and the HPV vaccine. Participants exhibited positive attitudes towards the HPV vaccine and perceived it as beneficial. However, there were multiple perceived barriers to vaccination, such as the need for parental consent, not being in school, concerns about vaccine side effects, and belief in myths and misinformation. Conclusion The adolescent girls in this study showed variable knowledge and positive attitudes toward the HPV vaccine despite the many perceived barriers. To support increased HPV vaccine acceptability and uptake among adolescent girls in Zambia, it is critical to actively engage stakeholders involved in HPV vaccination, such as adolescents and their parents, and debunk myths and misconceptions about HPV vaccination. Health education in schools and communities should be implemented to increase knowledge about HPV and HPV vaccination among adolescents and their parents.

Abstract
Introduction Many low- and middle-income countries have introduced the human papillomavirus (HPV) vaccine, but uptake remains extremely low. Malawi has the second-highest incidence of cervical cancer globally, and launched a national HPV vaccination program in 2019. We sought to understand attitudes about, and experiences with, the HPV vaccine among caregivers of eligible girls in Malawi. Methods We conducted qualitative interviews with 40 caregivers (parents or guardians) of preadolescent girls in Malawi to understand their experiences with HPV vaccination. We coded the data informed by the Behavioural and Social Drivers of vaccine uptake model and recommendations from WHO's Strategic Advisory Group of Experts Working Group on Vaccine Hesitancy. Results In this sample, 37% of age-eligible daughters had not received any HPV vaccine doses, 35% had received 1 dose, 19% had received 2 doses, and 10% had an unknown vaccination status. Caregivers were aware of the dangers of cervical cancer, and understood that HPV vaccine is an effective prevention tool. However, many caregivers had heard rumors about the vaccine, particularly its alleged harmful effect on girls' future fertility. Many caregivers, especially mothers, felt that school-based vaccination was efficient; but some caregivers expressed disappointment that they had not been more engaged in the school-based delivery of HPV vaccine. Caregivers also reported that the COVID-19 pandemic has been disruptive to vaccination. Conclusions There are complex and intersecting factors that affect caregivers' motivation to vaccinate their daughters against HPV, and the practical challenges that caregivers may encounter. We identify areas for future research and intervention that could contribute to cervical cancer elimination: better communicating about vaccine safety (particularly to address concerns about loss of fertility), leveraging the unique advantages of school-based vaccination while ensuring parental engagement, and understanding the complex effects of the COVID-19 pandemic (and vaccination program).

Abstract
This qualitative study using in-depth interviews and focus group discussions is the first to investigate HPV vaccination in The Gambia; it provides an in-depth analysis of uptake, knowledge, and perceptions of HPV vaccination as well as trust in Ministry of Health vaccination advice. Despite high uptake rates, knowledge of HPV vaccination was low, and the most prominent concern was that the vaccine could cause infertility or is a form of population control. Holistic approaches to addressing HPV vaccine concerns relating to fertility that consider socio-political contexts, including colonial histories, could lead to more positive vaccine perceptions, empowered decisions and to increasing vaccine uptake rates in The Gambia and elsewhere.

Abstract
AIM This study aimed to determine the knowledge and attitudes of physicians and nurses as parents about human papillomavirus (HPV) vaccination and their views on vaccination in children. MATERIALS AND METHODS This cross-sectional study included 72 physicians and 128 nurses who had children. Data were collected using questionnaires prepared by researchers. Descriptive statistical analysis and chi-square tests were used for data analysis. RESULTS In this study, 84.7% of physicians and 70.3% of the nurses knew that HPV is a cancer factor, and two-thirds of the healthcare professionals believed that the HPV vaccine is protective. Moreover, 62.5% of physicians and 74.2% of nurses reported that they did not intend to vaccinate their children. The reasons for vaccination hesitancy of healthcare professionals was believing it was unnecessary, thinking it was expensive, having insufficient knowledge about vaccine, thinking it may have side effects, and not trusting the vaccine. In this sample, 70.8% of physicians and 53.9% of nurses stated that they could have their children vaccinated only if the HPV vaccines were in the national vaccination schedule. DISCUSSION Further studies should be conducted to include the HPV vaccine in the childhood national vaccination program to reduce vaccine hesitancy.

Abstract
INTRODUCTION Cervical cancer is the second most common cancer and the second leading cause of cancer death among women in Ghana. HPV vaccination is expected to be added to the national vaccination schedule in 2023. This study aimed to: i) describe intentions to participate in HPV vaccination and ii) explore factors associated with vaccination intentions among female senior high school students in Ghana. METHODS Female students (aged 16-24) were recruited from 17 senior high schools in Ashanti Region. A cross-sectional anonymous self-report paper-and-pen survey assessed students' HPV vaccination intentions using three items, and a range of correlates (individual, parent/family, social networks, service provision). Descriptive statistics were calculated for vaccination intentions, and correlates of intention scores (where higher scores indicate stronger intentions) were explored with a linear mixed-effect model. RESULTS Of 2400 participants, 64% (95%CI: 62%, 67%) agreed with at least one vaccination intention item. Uncertainty and disagreement with at least one item were endorsed by 51% (95%CI: 49%, 53%) and 44% (95%CI: 42%, 46%) of students, respectively. One-quarter of the students (25%, 95%CI: 23%, 26%) agreed, 12% (95% 11%, 13%) disagreed, and 11% (95%CI: 10%,13%) indicated uncertainty, on all three vaccination intention items. Vaccination uptake was 4.5%. Students were likely to have higher vaccination intention scores if: they had stronger beliefs about vaccine effectiveness; vaccination was recommended by parents, religious leaders and service providers, and vaccinated peers; and it was free. Students were likely to have lower vaccination intention scores if they perceived barriers to vaccination (e.g., side effects). CONCLUSIONS While two-thirds of students had some intention to participate in HPV vaccination, vaccine hesitancy (i.e., uncertainty or disagreement) was apparent. Alongside the rollout of a free national vaccination programme, messaging about vaccination benefits and effectiveness targeting students, as well as parents, religious leaders, service providers and peers would be beneficial given their influential role in students' vaccination intentions.

Abstract
Tanzania has one of the highest cervical cancer incidence and mortality rates in sub-Saharan Africa. The Tanzanian Ministry of Health developed an integrated adolescent health program, HPV-Plus, that combines HPV vaccination with additional health services: nutritional assessments, vision screening, and vaccination for adolescent girls, and education for all genders. This qualitative descriptive study evaluated the acceptability of the HPV-Plus program in two districts in Tanzania. Key informants comprising of adolescent girls, parents, program planners, and program implementers in Njombe and Dar es Salaam Tanzania were interviewed to assess the program acceptability. Transcripts were analyzed using a team-based iterative thematic analysis approach, consisting of both inductive and deductive coding. The Theoretical Framework of Acceptability was used to guide analysis, with themes categorized according to theoretical constructs of intervention coherence, affective attitudes and perceptions, and perceived effectiveness. Overall acceptability of the HPV-Plus program was high among stakeholders. The most salient finding regarding factors that influenced HPV vaccine acceptability was largely related to education and knowledge levels surrounding the HPV, cervical cancer, and HPV vaccines. The educational component of the HPV-Plus program was key in increasing acceptability. Parents reported the lowest acceptability towards the program. This was found to be primarily due to perceptions of not being sufficiently engaged throughout program implementation. Increasing acceptability of HPV vaccination programs among key stakeholders is critical to facilitating vaccine uptake and meeting vaccination coverage targets. Our results demonstrate that the inclusion of a comprehensive education component within the HPV-Plus program was key in facilitating HPV vaccine acceptability amongst stakeholders.

Abstract
Administration of the human papillomavirus (HPV) vaccine in early adolescence is effective in preventing cervical cancer, a common cancer in sub-Saharan Africa. Nigeria is in the pre-introduction era of the HPV vaccine. Understanding the preferences of the population for the vaccine can help design the HPV immunization program to ensure high uptake of the vaccine. This study explored the preferences for the HPV vaccine among stakeholders in selected communities in Ibadan, Nigeria. A discrete choice experiment survey based on six attributes of the HPV vaccine (which were the number of doses, the efficacy of the vaccine, cost of the vaccine, location of the service point, other benefits of the vaccine apart from prevention of cervical cancer and the odds of a side effect from the vaccine) was carried out in five communities. Data were analyzed using conditional and mixed logit models. Seven hundred community members were recruited, 144 (20.7%) were adolescents and 248 (35.4%) were males. In line with expectations, respondents preferred vaccines with higher efficacy, less severe side effects and lower costs. Preference heterogeneity was identified for adolescents that were less price-sensitive and other community members who were less likely to prefer using schools as the service point. The high socioeconomic class preferred a vaccine that also prevents genital warts. There were variabilities in the preferences for the attributes of the HPV vaccine in the study communities. These variabilities need to be considered in the introduction of the HPV vaccine to ensure high uptake of the vaccine.

Abstract
Background Over 80% of new cervical cancer cases occur in women living in low- and middle-income countries. It is the second highest cause of female cancer deaths in Nigeria. School based vaccination programs are an effective strategy for delivering the HPV vaccine to adolescent girls. This study aims to understand the challenges to implementing school-based HPV vaccination programs, particularly in a remote rural setting where vaccine hesitancy is high. Methods A 22- item interviewer administered questionnaire was used to evaluate HPV knowledge and willingness to get the HPV vaccinate among 100 female secondary school students as part of an HPV vaccination pilot in a rural community in Kebbi State, Nigeria. Additionally, semi-structured interviews were used to assess community knowledge and attitudes on cervical cancer and HPV vaccination. Data collected were analyzed thematically to understand challenges and generate lessons for vaccine delivery in the study setting. Results Knowledge of HPV and cervical cancer among junior secondary school aged girls was fair with a mean score of 66.05%. For senior secondary school aged girls, the knowledge score ranged from 70 to 100% with a mean of 96.25% indicating good knowledge of HPV and cervical cancer. All participants (n = 100) received the first vaccine dose but due to COVID-19, 33 participants were not able to complete the vaccine dosage within the recommended 6-month schedule. Of the parents who provided consent, none could afford the vaccine out of pocket. Challenges to vaccine delivery included operational costs exacerbated by lack of adequate health workforce and infrastructure in the study setting. Conclusion An exploration of sociocultural perspectives and contextual realities is crucial to understanding the complexities of HPV vaccine introduction from the perspective of the target audience, and the local community. Strategies for introducing the HPV vaccine should address community concerns through effective communication, appropriate delivery, and targeted advocacy to make the vaccination program locally relevant. While school-based HPV immunization programs have been shown to be successful, adequate design, planning and monitoring is important. Additionally, considerations must be made to account for the high operational cost of vaccine delivery in rural, hard to reach areas where human resources and infrastructure are limited.

Abstract
Girls aged ≥9 years attending South African public sector schools are provided with free human papillomavirus (HPV) vaccination, through a schools-based programme. HPV vaccine misinformation spread via social media in 2014, was identified as a barrier to obtaining parental informed consent in some districts, including Sedibeng District, which subsequently had the lowest HPV vaccination coverage in Gauteng Province in 2018. This study investigated vaccine hesitancy in caregivers of girls in Grade 4 to 7 aged ≥9 years attending public schools in Sedibeng District. A cross-sectional survey using a self-administered questionnaire was conducted among caregivers of age-eligible girls attending all public schools in Sedibeng District with first dose HPV vaccination coverage of <70%. The questionnaire included demographics; HPV vaccination status of girls; reasons for not being vaccinated; and a 5-item tool measuring the determinants of vaccine hesitancy (5C scale), using a 7-point Likert scale. Data were coded and captured on Microsoft Excel®. Except for collective responsibility which was reverse scored, the other 5C items (confidence, complacency, constraints, and calculation) were captured as follows: 1 = strongly disagree, 2 = moderately disagree, 3 = slightly disagree, 4 = neutral, 5 = slightly agree, 6 = moderately agree and 7 = strongly agree. Descriptive and inferential statistical analyses were conducted using Epi InfoTM. Of the principals of all schools with <70% HPV vaccination coverage, 69.6% (32/46) gave permission. The response rate from caregivers of girls present on the day of data collection was 36.8% (1,782/4,838), with 67.1% (1,196/1,782) of respondents reporting that their daughters had received ≥1 dose of HPV vaccine. Only 63.1% (370/586) of respondents with unvaccinated daughters answered the question on reasons, with 49.2% (182/370) reporting reasons related to vaccine hesitancy. Statistically significant differences between caregivers of vaccinated and unvaccinated daughters were identified for four of the five determinants of vaccine hesitancy: confidence (vaccinated group higher), complacency (unvaccinated group higher), constraints (unvaccinated group higher) and collective responsibility (vaccinated group higher). This is the first South African study to (a) report results of the 5C scale, which was found to be very useful for predicting vaccination uptake; and (b) confirm that the relatively low HPV vaccination coverage in Sedibeng District is largely driven by reasons related to vaccine hesitancy.

Abstract
Parents have important roles to play for adolescents to get the human papillomavirus (HPV) vaccine, an effective measure in the prevention of cervical and other HPV-related cancers. It is important to understand the intention of parents to have their adolescents vaccinated for optimal uptake of the vaccine in Nigeria. This study investigated the intention of parents in five selected communities to get their adolescents vaccinated with HPV vaccine in Ibadan, Nigeria using the Integrated Behavioral Model (IBM). Cross sectional study design was employed and 678 parents were interviewed. Pearson correlation, chi-square test and multiple regression were used for data analysis at α = 0.05. Mean age of the parents was 42.5 ± 10.0 years and 230(33.9%) were males. Almost all of the parents (96.8%) had the intention to vaccinate their adolescents with HPV vaccine. This intention was significantly correlated with experiential attitude (r = 0.74, p = <.01), instrumental attitude (r = 0.33, p = <.01), injunctive norm (r = 0.39, p = <.01), descriptive norm (r = 0.32, p = <.01), perceived control (r = 0.32, p = <.01) and self-efficacy (r = 0.46, p ≤ .01). A higher proportion of parents older than 65 years significantly had no intention to vaccinate their adolescents with HPV vaccine. Intention to vaccinate adolescents with HPV vaccine was predicted by experiential attitude (OR = 0.88, 95% CI: 0.80-0.95), personal agency (OR = 0.22, 95% CI: 0.15-0.29) and injunctive norm (OR = 0.08, 95% CI: 0.02-0.13). Parental intention to vaccinate adolescents with HPV vaccine was high among the parents in this study. The reluctance of older parents about HPV vaccine for adolescents requires further investigation.
