Designing a Pro-Equity HPV Vaccine Delivery Program for Girls Who Have Dropped Out of School: Community Perspectives From Uttar Pradesh, India

Realist review of low- to upper-middle-income country experiences on integration of HPV vaccination with other adolescent health services

BACKGROUND

Integration of HPV vaccination with other adolescent health services may be associated with favorable programme outcomes including coverage, sustainability, and equitable delivery. Interest in such integrated approaches is building. However, the empirical evidence on how an integrated approach might be used to effectively deliver HPV vaccines and other adolescent health services has not been consolidated in a manner sufficient to inform policy and programmes.

METHODS

We conducted a realist synthesis review of published experiences from low- to upper-middle-income countries. Experts were invited as review commissioners, informing development and iteration of a programme theory of change (TOC). Our search strategy queried three large academic peer-review databases, grey literature, and a "snowball" of citations from key reference articles. We extracted learnings from specific real-world country experiences, exploring theoretical constructs describing the context in which an integration mechanism may deliver intended outcomes.

RESULTS

Of 1961 peer-reviewed articles and 16 grey literature articles identified, 8 articles met inclusion criteria, providing data from 6 country experiences to develop an iterated TOC. There were notable gaps in evidence regarding how an integrated approach might meet unique needs of underserved populations, including out of school youth and those affected by HIV. TOC iterations yielded 9 new factors and 4 discarded factors. Notable new factors included a multisectoral cooperation mechanism, linked to the use of a large number of other mechanisms, including integration of cost-sharing, supply chain distribution, and programme monitoring.

CONCLUSION

This realist synthesis is to our knowledge the first review consolidating operational evidence on how an integrated approach might be used to effectively deliver HPV vaccines and other adolescent health services. Our iterated TOC provides a framework to guide future implementation research, to ensure attribution of observed effects to an integrated approach is merited - and to inform decision-making in adolescent immunization policy and programmes.

Assessment of Knowledge, Awareness, and Practices of Human Papillomavirus Infection and Vaccination Among Medical and Dental Students: A Cross-Sectional Study

Introduction Human papillomavirus (HPV) is the most common causative agent for cervical cancer (CC) in women. Despite extensive initiatives, the acceptance and implementation of vaccinations have remained inadequate, hindering a significant impact on public health outcomes. This study aimed to provide a comprehensive assessment of the knowledge, awareness, and practices (KAP) scores of medical and dental students regarding HPV infection and vaccination. Materials and methods A cross-sectional online survey was conducted among 580 students, including 290 Bachelor of Dental Surgery (BDS) students and 290 Bachelor of Medicine, Bachelor of Surgery (MBBS) students. The questionnaire comprised four distinct sections: the demographic section encompassed variables including age, gender, academic year, field of study, and vaccination status. The knowledge assessment section featured eight multiple-choice inquiries, the awareness assessment incorporated eight multiple-choice items, and the practice assessment consisted of four questions using a 5-point Likert scale. Google Forms links, accompanied by a set of instructions and consent forms, were randomly dispatched via WhatsApp to the participants. Data was subjected to statistical analysis. Results A total of 416 responses were obtained (180 BDS and 236 MBBS), amounting to a 71.2% response rate. MBBS participants had a significantly higher mean knowledge score of 7.14 than BDS participants (6.38) (p = 0.001). Males exhibited a significantly higher mean knowledge score than females (p = 0.009). Across the study years, the highest mean knowledge score was observed among first-year students, with a significant difference among years (p = 0.001). For awareness scores, MBBS participants had a significantly higher mean score of 6.90, compared to the BDS participants of 6.36 (p = 0.001). Regarding practice, MBBS participants had a significantly higher mean score of 16.02 than BDS participants of 15.18 (p = 0.001). The study year displayed the strongest correlation with knowledge (r = 0.39), while the correlations with awareness (r = 0.13) and practice (r = 0.01) were found to be weak. Conclusions Low KAP scores were observed in both medical and dental students for HPV infection, CC, and vaccination.

Acceptability of HPV vaccination for cervical cancer prevention amongst emerging adult women in rural Mysore, India: a mixed-methods study

BACKGROUND

India has the highest number of estimated deaths from cervical cancer globally, with most cases attributed to Human papillomavirus (HPV). The World Health Organization recommends primary HPV vaccination for girls ages 9-14, with catch-up vaccination for young women ≥ 15 if feasible. India authorized a new, inexpensive HPV vaccine in 2022; given anticipated vaccine expansion, we conducted a mixed-methods study exploring acceptability of HPV catch-up vaccination for young emerging adult women in rural Mysore, India.

METHODS

Between September 2022-April 2023, participants were recruited with assistance from community health workers. In the qualitative phase, gender-stratified, audio-recorded focus group discussions (FGDs) were conducted in Kannada with emerging adults ages 18-26. FGDs were transcribed, translated, and analyzed using rapid approach to identify key HPV vaccination attributes. In the quantitative phase, a conjoint analysis was conducted to assess the impact of seven vaccination attributes on likelihood to vaccinate (LTV). Women ages 18-26 ranked LTV in eight hypothetical vaccination scenarios, and the relative impact of each attribute on LTV was calculated. All participants received education about cervical cancer, HPV, and HPV vaccination.

RESULTS

Fifty-two young adults (female = 31, male = 21) participated in seven FGDs, and 101 women participated in the conjoint analysis. Average age of the 153 participants was 22.5 years, 66.7% had married, and all had completed high school. Only 17.9% had heard of cervical cancer, and 2.7% knew of the HPV vaccine. FGDs identified seven HPV vaccination attributes: cost, vaccination location, family support, peer influence, dose number, side effects, and risk of acquiring HPV. In the conjoint analysis, all attributes except dose number significantly impacted LTV. Family support (impact score = 19.37, p < 0.0001) and peer influence (impact score = 18.01, p < 0.0001) had the greatest influence, followed by cost (impact score = 16.64, p < 0.0001) and HPV risk (impact score = 12.31, p < 0.0001). Vaccination location (government centers preferred) and side effects were also significant.

CONCLUSION

Participants had poor knowledge of cervical cancer and HPV. Social attributes (family support, peer influence) had greatest impacts on LTV, and future studies should explore family-based interventions and peer education. Providing free vaccines at government centers through India's national immunization program would maximize catch-up HPV vaccination for rural young women.

Integrating HPV vaccine service delivery with adolescent health programmes - Experiences and perspectives from selected countries in Africa

Primary prevention of human papillomavirus (HPV) infection is particularly important in Africa, where there is a high and accelerating burden of cervical cancer. Stakeholders have increasingly called for integration of other services with HPV vaccination in low- and middle-income countries, yet successful and sustainable integration requires intensive resource inputs, and few countries in Africa have tested integrated approaches. We describe co-author experience and previously published assessments to present the experiences of four African countries, Senegal, Togo, Tanzania, and Lesotho, with integrating HPV vaccine services with other programmes and services. The resulting case series explores how countries are operationalizing the concept of integration and describes contextual factors for success and sustainability. A simple three-level framework for describing HPV vaccine integrated service delivery has emerged to guide future endeavors.

Selecting and Tailoring Implementation Strategies to Improve Human Papillomavirus Vaccine Uptake in Zambia: A Nominal Group Technique Approach

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.

Gender-Neutral HPV Vaccine in India; Requisite for a Healthy Community: A Review

Human papillomavirus (HPV) affects approximately 80% of individuals, irrespective of gender, and is implicated in various cancers. Existing HPV vaccines, while safe and effective, do not sufficiently protect males when administered solely to females. This review, triggered by the urgent need to address this gap and reduce the associated stigma, aims to evaluate the introduction of a gender-neutral HPV vaccine, GARDASIL-9, in India. The primary objective is to assess the necessity and feasibility of incorporating the gender-neutral HPV vaccine into India's national immunization program. This integration is crucial to ensure equitable access for all children and to mitigate the substantial burden of HPV. A literature search was conducted using databases such as Google Scholar, PubMed, government websites, and relevant publications. Keywords included "gender-neutral vaccine", "HPV vaccine", and "Indian population". The central research question guiding this review is: How necessary and feasible is the inclusion of a gender-neutral HPV vaccine in India's national immunization schedule to ensure equitable access for all children and reduce the HPV burden? The review inclusion criteria comprised studies addressing the prevalence of HPV infections, HPV vaccination awareness among both genders, the cost-effectiveness of gender-neutral vaccines, current HPV vaccination status, and future perspectives specific to India. Studies not meeting these criteria were excluded. The review highlights that introducing a gender-neutral HPV vaccine in India is imperative. Including males in vaccination efforts significantly reduces the overall disease burden and helps in reducing the stigma associated with HPV. A comprehensive vaccination program, bolstered by education and awareness campaigns, and its inclusion in the national immunization schedule is essential. This approach ensures equitable access to the vaccine for all children, fostering a healthier community, preventing HPV-related cancers, and enhancing public health outcomes in India.

The impact of health education interventions on HPV vaccination uptake, awareness, and acceptance among people under 30 years old in India: a literature review with systematic search

Background

The HPV vaccine is used as one of the main prevention tools for HPV-related cancers globally, yet it is not part of the Indian National Immunization program. In light of the introduction of the indigenous vaccine, we examine the effectiveness of health education about uptake, acceptance, and awareness.

Methods

Research was performed in the following databases: PubMed, CINAHL, Scopus, and Embase to identify studies between 2008 and 2022. Studies were included if: they were conducted in India including primary data research and health education intervention, and participants were between 9 and 29 years old.

Results

Out of the 10.952 results, 7 studies were included. Four studies focused on adolescent girls, aged from 9 to 20 years old, and 3 on university students aged from 17 to 26 years. Five studies were implemented in urban areas and 2 in rural areas. Health education interventions proved to be effective in increasing uptake, awareness, and acceptance of the HPV vaccine. The barriers included among others: cost, lack of awareness, and cultural barriers.

Conclusion

Observations from this study outline immediate action for policymakers to educate and encourage the young population toward HPV vaccination. Future programs should be aimed at different population groups and be adjusted according to their special characteristics and needs. Attention should be given to the male population and marginalized groups. The involvement of various stakeholders proved to be beneficial, and it is highly recommended.

Uncovering the Drivers of Childhood Immunization Inequality with Caregivers, Community Members and Health System Stakeholders: Results from a Human-Centered Design Study in DRC, Mozambique and Nigeria

BACKGROUND

The importance of immunization for child survival underscores the need to eliminate immunization inequalities. Few existing studies of inequalities use approaches that view the challenges and potential solutions from the perspective of caregivers. This study aimed to identify barriers and context-appropriate solutions by engaging deeply with caregivers, community members, health workers, and other health system actors through participatory action research, intersectionality, and human-centered design lenses.

METHODS

This study was conducted in the Demographic Republic of Congo, Mozambique and Nigeria. Rapid qualitative research was followed by co-creation workshops with study participants to identify solutions. We analyzed the data using the UNICEF Journey to Health and Immunization Framework.

RESULTS

Caregivers of zero-dose and under-immunized children faced multiple intersecting and interacting barriers related to gender, poverty, geographic access, and service experience. Immunization programs were not aligned with needs of the most vulnerable due to the sub-optimal implementation of pro-equity strategies, such as outreach vaccination. Caregivers and communities identified feasible solutions through co-creation workshops and this approach should be used whenever possible to inform local planning.

CONCLUSIONS

Policymakers and managers can integrate HCD and intersectionality mindsets into existing planning and assessment processes, and focus on overcoming root causes of sub-optimal implementation.

Evidence on factors influencing HPV vaccine implementation in South Asia: A scoping review

Cervical cancer is a significant public health concern globally, with low and middle-income countries bearing the highest burden, specifically the South Asian region. Therefore, the current scoping review aimed to highlight the factors influencing the implementation of human papillomavirus (HPV) vaccination in South Asia. Adopting the 'Arksey and O'Malley and Levac et al.' methodology, multiple electronic databases were searched to identify relevant records. The results were narratively synthesised and discussed, adopting the Consolidated Framework for Implementation Research (CFIR) model. We identified 527 records, which were assessed for eligibility based on title, abstract, and full text by three reviewers, followed by data extraction of 29 studies included for analysis in the review. Implementing HPV vaccination programs in South Asia faces various challenges, such as economic, health system, financial, health literacy, and sociocultural factors that hinder their successful implementation. To successfully implement the vaccine, a tailored risk communication strategy is necessary for these countries. Knowledge gained from the experience of South Asian nations in implementing the HPV vaccine can assist in policymaking in similar healthcare for advancing the implementation of HPV vaccination.
