Preparing for HPV vaccination in South Africa: Key challenges and opinions

Communication strategies to improve human papillomavirus (HPV) immunisation uptake among adolescents in sub-Saharan Africa: a systematic review and meta-analysis

OBJECTIVES

Developing countries face the greatest cervical cancer disease burden and mortality with suboptimal immunisation uptake. This review explores the communication strategies adopted, successes, challenges and lessons learnt in sub-Saharan countries to enhance human papillomavirus (HPV) immunisation.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PubMed, Hinari, Cochrane Library, Trip database, CINAHL, Web of Science, Scopus and seven grey resources were searched through May 2022.

ELIGIBILITY CRITERIA

We included observational studies addressing communication strategies for HPV immunisation uptake.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers used standardised methods to search, screen and code included studies. Data extraction and assessment of risk of bias were done in duplicate to enhance validity of the results. Meta-analysis was conducted using the random-effects model. Findings were summarised and synthesised qualitatively.

RESULTS

Communication intervention to facilitate decision-making achieved uptake rate of 100% (95% CI 0.99% to 1.00%), followed by intervention to enable communication, which achieved 92% (95% CI 0.92% to 0.92%). Communication intervention to inform and educate achieved 90% (95% CI 0.90% to 0.90%).Targeting both healthcare workers and community leaders with the communication intervention achieved 95% (95% CI 0.91% to 0.98%), while teachers and school boards achieved 92% (95% CI 0.84% to 1.01%). Targeting policymakers achieved 86% (95% CI 0.78% to 0.93%).Based on the method of communication intervention delivery, use of training achieved an uptake rate of 85% (95% CI 0.84% to 0.87%); similarly, drama and dance achieved 85% (95% CI 0.84% to 0.86%). However, use of information, education and communication materials achieved 82% (95% CI 0.78% to 0.87%).

CONCLUSION

HPV vaccine communication is critical in ensuring that the community understands the importance of vaccination. The most effective communication strategies included those which educate the population about the HPV vaccine, facilitate decision-making on vaccine uptake and community ownership of the vaccination process immunisation.

A story-telling cloth approach to motivating cervical cancer screening in Mali

Ninety percent of deaths from Cervical cancer (CC) caused by Human Papilloma Virus (HPV) occur in low- and middle-income countries. CC is the 2nd most common cause of cancer in women in West Africa, where 12,000 women develop cervical cancer and more than 6,000 die from the disease, annually. While HPV vaccination and CC screening have dramatically reduced the incidence of CC and mortality from CC in developed countries, prevention of CC in West Africa is often limited to visual inspection of the cervix and surgical intervention. In previous studies of CC in Mali, we demonstrated that knowledge about the link between HPV and CC is limited, and that screening for CC is often delayed until women are symptomatic. For this intervention, a story-telling cloth (West African-style printed pagne) was designed for use as a starting point for educational sessions run by community health workers. Community outreach using the cloth during 6 months of 2015 resulted in a 5-fold higher uptake of cervical cancer screening and increased awareness of the potential to vaccinate adolescents against CC. 3,271 women were motivated to visit one of five participating clinics for CC screening, where a mere 600 women had been screened during the previous year. This study shows that a comprehensive, visual, community-centered education campaign coupled with coordinated support for local clinics improves uptake of CC screening.

Microbiological and behavioral determinants of genital HPV infections among adolescent girls and young women warrant the need for targeted policy interventions to reduce HPV risk

BACKGROUND

Genital human papillomavirus (HPV) is the most common sexually transmitted virus in most populations globally. Adolescent girls and young women (AGYW) remain a key population group at risk for HPV infection. However, the risk factors of HPV infection among AGYW, especially in sub-Saharan Africa, are a subject of little investigation in published literature. Here, we investigated the factors associated with HPV infection among unvaccinated South African AGYW with a high HPV burden (prevalence: 76.1%).

METHODS

We retrospectively recruited 213 AGYW learners (aged 15-25 years) from a previous cross-sectional study, the HPV Education Intervention Study, conducted in the Eastern Cape, South Africa. Sexually transmitted infections (STIs), bacterial pathobionts, genital ulcers (due to infectious causes), candidiasis, and bacterial vaginosis (BV) in the self-collected vaginal specimens were determined using the Allplex™ Panel Assays. Statistical analyses were performed using STATA v16.1. Continuous and categorical variables were computed by t-test /Wilcoxon rank-sum test and Chi-square/Fisher's exact tests, respectively. Logistic regression was used to determine the univariable predictors of HPV infection.

RESULTS

The overall detection rate of any viral STI, bacterial STI, pathobiont, genital ulcer, candidiasis, and BV among the AGYW was 75.0, 34.4, 90.7, 14.4, 26.9, and 43.6%, respectively. The main factors associated with HPV infection were alcohol consumption (p = 0.005), infection with any and multiple Candida species (p = 0.011 and 0.006, respectively), Candida albicans infection (p = 0.010), Ureaplasma urealyticum pathobiont infection (p = 0.044), BV-associated bacteria (specifically Atopobium vaginae: p = 0.039, BV-associated bacteria 2: p = 0.021, Gardnerella vaginalis: p = 0.021, Megasphaera type 1: p = 0.037), and BV (p = 0.011).

CONCLUSIONS

Our study, albeit not necessarily generalizable, found social behavior as well as specific vaginal microbes as correlates of HPV infection among AGYW in South Africa. There is a need to investigate HPV epidemiology in other AGYW populations. The factors associated with genital HPV infection among AGYW burdened with HPV infection necessitate the need to formulate and implement population-specific public health strategies for creating HPV awareness and reducing its risk.

Parental intention to vaccinate adolescents with HPV vaccine in selected communities in Ibadan, Southwest Nigeria: an application of Integrated Behavioral Model

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.

Predictors of COVID-19 Vaccine Hesitancy in South African Local Communities: The VaxScenes Study

South Africa launched a mass COVID-19 vaccination campaign in May 2021, targeting 40 million adults. Understanding predictors of COVID-19 vaccine intentions was required to achieve this goal. We conducted a population-based survey in June–July 2021 using the WHO Behavioral and Social Drivers (BeSD) of COVID-19 Vaccination tool to determine predictors of vaccine hesitancy, defined as intention to refuse or uncertainty whether to accept COVID-19 vaccination. There were 1193 participants, mean age 39 (standard deviation 15) years, and 53% women, of whom 58% trusted information provided by healthcare workers and 32% were vaccine hesitant. Independent predictors of vaccine hesitancy included concerns about side effects (odds ratio (OR) 11.41; 95% confidence interval (CI) 3.5–50.80), lack of access to the online vaccine registration platform (OR 4.75; CI 2.15–10.37), distrust of government (OR 3.0; CI 1.33–6.77), belief in conspiracy theories (OR 3.01; CI 1.32–6.77), having no monthly income (OR 1.84; CI 1.12–3.07), and depending on someone else to make vaccination decision (OR 2.47; CI 1.06–5.77). We identified modifiable predictors of vaccine hesitancy at the start of South Africa’s COVID-19 vaccination rollout. These factors should be addressed by different stakeholders involved in the national immunization program through tailored communication and other effective strategies that increase vaccine literacy, reach low-income households, and engender confidence in government.

COVID-19 vaccine hesitancy in South Africa: how can we maximize uptake of COVID-19 vaccines?

Introduction: Acceptance of COVID-19 vaccines is critical to personal health, protecting vulnerable populations, reopening socio-economic life, and achieving population health and safety through immunity. The primary aim of this review was to investigate the extent and determinants of COVID-19 vaccine hesitancy in South Africa to inform the development of strategies to address it. A secondary aim was to enhance understandings of and responses to vaccine hesitancy more generally in South Africa, with potential positive effect on vaccination uptake during and beyond the COVID-19 pandemic.Areas covered: We reviewed the findings from surveys conducted in South Africa from February 2020 to March 2021 that investigated acceptance of COVID-19 vaccines. Surveys were identified through searching electronic databases of peer-reviewed and gray literature and contacting experts.Expert opinion: The review reveals the inherently social nature of COVID-19 vaccine hesitancy in South Africa, potentially influenced by age, race, education, politics, geographical location, and employment. Along with the provision of information, COVID-19 vaccine communication strategies need to form part of broader trust-building measures that focus on relationships, transparency, participation, and justice. The pandemic also provides a unique opportunity to positively intervene and reduce vaccine hesitancy trends more generally in South Africa and potentially elsewhere.

Stakeholders' Understandings of Human Papillomavirus (HPV) Vaccination in Sub-Saharan Africa: A Rapid Qualitative Systematic Review

Cervical cancer rates in Sub-Saharan Africa (SSA) are amongst the highest worldwide. All three of the Human Papillomavirus (HPV) vaccines (9-valent, quadrivalent and bivalent HPV vaccine) provide primary protection against the most common cancer-causing strains of HPV (types 16 and 18) that are known to cause 70% of cervical cancers. Over the last five years, there has been an increase in Sub-Saharan African countries that have introduced the HPV vaccine. The majority of research has been conducted on supply-side barriers and facilitators to HPV vaccination uptake in SSA, yet little research has been conducted on demand-side or end-user perspectives of, and decisions around, HPV vaccination. In order to complement existing research, and inform current and future HPV vaccination implementation approaches, this qualitative systematic review explored Stakeholders' understandings of HPV vaccination in SSA. This review searched the following databases: Embase (via Scopus), Scopus, MEDLINE (via PubMed), PubMed, EBSCOhost, Academic Search Premier, Africa-Wide Information, CINAHL, PsycARTICLES, PsycINFO, SocINDEX, Web of Science, and the Cochrane Controlled Register of Trials (CENTRAL) and found a total of 259 articles. Thirty-one studies were found eligible for inclusion and were analyzed thematically using Braun and Clarke's methods for conducting a thematic analysis. The quality of included studies was assessed using the Critical Appraisal Skills Programme (CASP) checklist. Three major themes emerged from this analysis; knowledge of HPV vaccination and cervical cancer is intertwined with misinformation; fear has shaped contradictory perceptions about HPV vaccination and gender dynamics are relevant in how stakeholders understand HPV vaccination in SSA.

Health systems constraints and facilitators of human papillomavirus immunization programmes in sub-Saharan Africa: a systematic review

Given the vast investments made in national immunization programmes (NIPs) and the significance of NIPs to public health, it is important to understand what influences the optimal performance of NIPs. It has been established that well-performing NIPs require enabling health systems. However, systematic evidence on how the performance of health systems impacts on NIPs is lacking, especially from sub-Saharan Africa. We conducted a qualitative systematic review to synthesize the available evidence on health systems constraints and facilitators of NIPs in sub-Saharan Africa, using human papillomavirus immunization programmes as a proxy. Fifty-four articles published between 2008 and 2018 were found to be eligible. Data extraction was guided by an analytical model on the interface between NIPs and health systems. A cross-cutting thematic analysis of the extracted data was performed. This systematic review provides evidence necessary for informing ongoing health systems strengthening initiatives in sub-Saharan Africa. There is evidence to suggest that NIPs in sub-Saharan Africa have surmounted significant health systems constraints and have achieved notable public health success. This success can be attributed to strong political endorsement for vaccines, clear governance structures and effective collaboration with global partners. Despite this, significant health systems constraints persist in service delivery, vaccine communication, community engagement, the capacity of the health workforce and sustainable financing. These constraints could derail further progress if not addressed through health systems strengthening efforts. There is a need to expand the research agenda to include the comprehensive evaluation of health systems constraints and facilitators of NIPs within sub-Saharan Africa.

Knowledge, attitude and uptake of human papillomavirus vaccination among female undergraduates in Lagos State, Nigeria

Background and Aims

Human papillomavirus (HPV) is a known cause of cervical cancer which is the second-most common cancer among women worldwide. HPV vaccination is a primary prevention to reduce the occurrence of cervical cancer. This study assessed knowledge, attitude and uptake of HPV vaccine among female undergraduates in Lagos State Polytechnic (LASPOTECH).

Methods

A descriptive cross-sectional survey was conducted among 400 female undergraduates of LASPOTECH in August 2018. Participants were selected using a multi-stage sampling technique and data was collected with a pretested, self-administered, semi-structured questionnaire. Univariate and bivariate analyses were conducted using IBM SPSS version 20. Statistically significant level was set at P ≤ 0.05.

Results

Mean age of respondents was 21.3 ± 2 years. Only 11 (3%) of the respondents had good knowledge of HPV and the vaccine. However, majority of the respondents 356 (92.7%) had positive attitude towards uptake of HPV vaccine. Only 10 (2.6%) of the respondents had received a single dose of HPV vaccine. Age, level of study and number of sexual partners of the respondents were statistically significantly associated with knowledge and attitude towards the HPV vaccine (P ≤ 0.05). The most common reason stated by the respondents for none uptake of HPV vaccine was lack of information.

Conclusion

Knowledge and uptake of HPV vaccination among the respondents were poor. However, majority had positive attitude towards uptake of the vaccine. It is recommended that information on HPV and the vaccine should be made available to increase the knowledge and the uptake among female undergraduates in Lagos State.

Social media and HPV vaccination: Unsolicited public comments on a Facebook post by the Western Cape Department of Health provide insights into determinants of vaccine hesitancy in South Africa

On the 4 February 2019, the Western Cape Department of Health's Facebook page announced the implementation of a school-based vaccination campaign aimed to administer the first doses of human papillomavirus (HPV) vaccine in public schools to Grade 4 girls who are nine years old. This announcement was met with a flurry of social media responses posted on the campaign's Facebook page. This study identifies determinants of vaccine hesitancy amongst responses provided by social media users to this post. On 8 March 2019, we conducted a qualitative study including all 157 comments to the Facebook post. The post had 659 'emotion' reactions: 574 "likes", 62 "loves", 21 "angry faces", 2 "laughs", 2 "wows" and 1 "sad face". An overwhelming majority (636/659 i.e. 97%) of reactions were favourable to the HPV vaccination campaign. Out of the 157 comments, we judged 52 (33%) of them to be 'hesitant', suggesting that people with negative reactions though few in number, were more likely to be vocal deniers. Concern around the safety of HPV vaccines including effects on reproductive health was the most common theme identified. Other emerging themes included: risk of cervical cancer perceived as being low, issues around consent, concerns that girls are being used for research, questionable vaccine effectiveness, use of the school-based strategy for the campaign, risk-benefits calculations of HPV vaccination and constraints such as stock-outs. Knowing someone who had been affected or being at risk of cervical cancer, having knowledge about the causes of cervical cancer, confidence in the effectiveness and safety of the vaccine, knowing the vaccine was being used in high income settings, and having strong recommendations from the World Health Organisation and key actors seemed to increase the willingness to accept the vaccine. The magnitude and causes of HPV vaccine hesitancy need to be investigated to ensure the success of this programme.

Human Papillomavirus Vaccine Introduction in South Africa: Implementation Lessons From an Evaluation of the National School-Based Vaccination Campaign

Evaluation of the campaign confirmed its feasibility in this setting: it achieved high coverage, few adverse events, and mostly positive media coverage. However, challenges occurred in data and cold chain management. Future implementation requires improved partnerships between government ministries, simplified informed consent, and closer monitoring of social media messaging.

Background:

In April 2014, a national school-based human papillomavirus (HPV) vaccination program was rolled out in South Africa, targeting Grade 4 girls aged ≥9 years. A bivalent HPV vaccine with a 2-dose (6 months apart) schedule was used. At the request of the National Department of Health (NDoH), we conducted an external assessment of the first-dose phase of the vaccination program to evaluate program coverage and vaccine safety and identify factors that influenced implementation.

Methods:

We based our cross-sectional and mixed-methods approach on a process evaluation framework, which included a review of key planning and implementation documents and monitoring data; observation at vaccination sites; key informant interviews (N=34); and an assessment of media coverage and content related to the campaign.

Findings: There was overall success in key measures of coverage and safety. Over 350,000 Grade 4 girls were vaccinated in more than 16,000 public schools across South Africa, which translated to 94.6% of schools reached and 86.6% of age-eligible learners vaccinated. No major adverse events following immunization were detected. We attributed the campaign's successes to careful planning and coordination and strong leadership from the NDoH. The primary challenges we identified were related to obtaining informed consent, vulnerabilities in cold chain capacity, and onsite management of minor adverse events. While campaign planners anticipated and prepared for some negative media coverage, they did not expect the use of social media for spreading misinformation about HPV vaccination.

Conclusions:

The first phase of the national school-based HPV vaccination campaign was successfully implemented at scale in this setting. Future implementation will require improvement in the storage and monitoring of vaccine doses, better communication of role expectations to all stakeholders, and streamlined consent processes to ensure program sustainability.

"She must have been sleeping around"…: Contextual interpretations of cervical cancer and views regarding HPV vaccination for adolescents in selected communities in Ibadan, Nigeria

Background

Human Papilloma virus (HPV) vaccines for adolescents are pivotal in the control of cervical cancer, the commonest women specific malignancy in sub-Saharan Africa. Knowledge about cervical cancer have been reported to be low in Africa but expressed acceptability for HPV vaccines have been high. The reason for this mismatch is not clear. An understanding of the interpretation of cervical cancer and views about HPV vaccine are important as they can affect actual decision making regarding adolescents’ uptake of HPV vaccine. This study explored contextual interpretations of stakeholders regarding cervical cancer and HPV vaccines for adolescents in five selected communities in Ibadan, Nigeria.

Methods

Qualitative data were collected through twenty focus group discussions among parents of adolescents, religious and traditional leaders, school teachers and adolescents; and four key informant interviews with the identified traditional healers in the selected communities. Constant comparison analysis was done after transcription.

Results

Almost every group had at least one person who had seen a cervical cancer patient. Cervical cancer was widely viewed as being caused by promiscuity of women while older participants believed that the alteration of lifestyle by civilization was a major contributory factor. There was also a general notion that it was due to a curse. The role of HPV was generally not known. Most participants were favourable towards HPV immunization for adolescents but traditional healers and some religious leaders were not. The high cost of the vaccines and possibility of side effects where the main concerns about the introduction of HPV vaccine. Decision to take the vaccine rest with the fathers whose views were heavily influenced by traditional and religious leaders.

Conclusions

Awareness about cervical cancer may not be as low as earlier reported and there were many misconceptions about cervical cancer in the study communities. It is important to address these misconceptions to ensure successful introduction of HPV vaccine for adolescents in future.

Perceptions of human papillomavirus vaccination of adolescent schoolgirls in western Uganda and their implications for acceptability of HPV vaccination: a qualitative study

Background

Human papillomavirus (HPV) vaccination has been perceived in diverse ways some of which encourage its uptake while others could potentially deter its acceptability. This study explored community member’s perceptions about HPV vaccination in Ibanda district and the implications of the perceptions for acceptability of HPV vaccination. The study was conducted following initial vaccination of adolescent schoolgirls in the district between 2008 and 2011.

Methods

This qualitative study employed focus group discussions (FGDs) and key informant interviews (KIIs). FGDs were conducted with schoolgirls and parents/guardians and KIIs were conducted with school teachers, health workers and community leaders. Transcripts from the FGDs and KIIs were coded and analyzed thematically using ATLAS.ti (v. 6).

Results

The HPV vaccination was understood to safely prevent cervical cancer, which was perceived to be a severe incurable disease. Vaccinations were perceived as protection against diseases like measles and polio that were known to kill children. These were major motivations for girls’ and parents’ acceptance of HPV vaccination. Parents’ increased awareness that HPV is sexually transmitted encouraged their support for vaccination of their adolescent daughters against HPV. There were reports however of some initial fears and misconceptions about HPV vaccination especially during its introduction. These initially discouraged some parents and girls but over the years with no major side effects reported, girls reported that they were willing to recommend the vaccination to others and parents also reported their willingness to get their daughters vaccinated without fear. Health workers and teachers interviewed however explained that, some concerns stilled lingered in the communities.

Conclusions

The perceived benefits and safety of HPV vaccination enhanced girls’ and parents’ acceptability of HPV vaccination. The initial rumors, fears and concerns about HPV vaccination that reportedly discouraged some girls and parents, seemed to have waned with time giving way to more favourable perceptions regarding HPV vaccination although the study still found that a few concerns still lingered on and these have implications for HPV vaccination acceptability.

Experiences and lessons learned from 29 HPV vaccination programs implemented in 19 low and middle-income countries, 2009-2014

BACKGROUND

Cervical cancer is the greatest cause of age-weighted years of life lost in the developing world. Human papillomavirus (HPV) infection is associated with a high proportion of cervical cancers, and HPV vaccination may help to reduce the incidence of cancer. The aim of the study was to identify barriers, obstacles, and strategies and to analyze key concerns and lessons learned with respect to the implementation of HPV vaccination program in low- and middle-income countries.

METHODS

The Gardasil Access Program (GAP) is a donation program established to enable organizations and institutions in eligible low-resource countries to gain operational experience designing and implementing HPV vaccination programs. This study used an online survey to capture the experiences and insights of program managers participating in the GAP. Different factors related to HPV vaccination program management were collected. A mixed-method approach enabled the presentation of both quantitative measurements and qualitative insights.

RESULTS

Twenty-nine programs implemented by 23 institutions in 19 low- and middle-income countries were included. Twenty programs managers (97.7 %) reported that their institution implemented sensitization strategies about vaccination prior to the launch of vaccination campaign. The most frequently reported obstacles to HPV vaccination by the program managers were erroneous perceptions of population related to the vaccine's safety and efficacy. Reaching and maintaining follow-up with target populations were identified as challenges. Insufficient infrastructure and human resources financing and the vaccine delivery method were identified as significant health system barriers. Coupling HPV vaccination with other health interventions for mothers of targeted girls helped to increase vaccination and cervical cancer screening. The majority of program managers reported that their programs had a positive impact on national HPV vaccination policy. The majority of institutions had national and international partners that provided support for human resources, technical assistance, and training and financial support for health professionals.

CONCLUSION

Local organizations and institutions can implement successful HPV vaccination campaigns. Adequate and adapted planning and resources that support information sharing, sensitization, and mobilization are essential for such success. These results can inform the development of programs and policies related to HPV vaccination in low- and middle-income countries.

Knowledge, attitudes and practices on adolescent vaccination among adolescents, parents and teachers in Africa: A systematic review

INTRODUCTION

Vaccines are the most successful and cost-effective public health interventions available to avert vaccine-preventable diseases and deaths. Despite global progress in adolescent health, many adolescents in Africa still get sick and die from vaccine-preventable diseases due to lack of vaccination. Adolescents, parents and teachers are key players in the development and implementation of adolescent vaccination policies. Optimal knowledge, attitudes and practices towards adolescent vaccination among these key players may improve vaccine uptake among adolescents. We conducted a qualitative and quantitative systematic review on knowledge, attitudes and practices of adolescent vaccination among adolescents, parents and teachers in Africa.

METHODS

We searched PubMed, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, WHOLIS, Africa Wide and CINAHL for eligible quantitative and qualitative primary studies with no time limits. We also checked reference lists of included studies for eligible studies and searched grey literature. Two authors independently screened the search outputs, selected studies and extracted data; resolving discrepancies by consensus and discussion. Qualitative data were analysed using thematic analyses where applicable, while analyses from quantitative studies used different methods based on the type of outcomes.

RESULTS

We included 18 cross-sectional studies in this review. The included studies were conducted in 10 out of the 54 countries in Africa. The 18 studies focused on a wide range of adolescent vaccines. Thirteen studies evaluated vaccines against Human Papilloma Virus, while each of the remaining 5 studies, evaluated vaccines against rabies, HIV, tetanus toxoid, tuberculosis and adolescent vaccines in general. Among the key players, we found low to moderate levels of knowledge about adolescent vaccination. Positive attitudes and practices towards adolescent vaccination, especially against Human Papilloma Virus were reported. Despite the low knowledge, our results showed high levels of acceptability to adolescent vaccination among adolescents, parents and teachers.

CONCLUSIONS

It was evident in our review that all key demographics (parents, adolescents and teachers) were receptive towards adolescent vaccines. We propose relevant policy makers in Africa to consider continuous education programs such as those aimed to inform the parents, adolescents and teachers on adolescent vaccination.

Cervical cancer prevention and treatment research in Africa: a systematic review from a public health perspective

BACKGROUND

Women living in Africa experience the highest burden of cervical cancer. Research and investment to improve vaccination, screening, and treatment efforts are critically needed. We systematically reviewed and characterized recent research within a broader public health framework to organize and assess the range of cervical cancer research in Africa.

METHODS

We searched online databases and the Internet for published articles and cervical cancer reports in African countries. Inclusion criteria included publication between 2004 and 2014, cervical cancer-related content pertinent to one of the four public health categories (primary, secondary, tertiary prevention or quality of life), and conducted in or specifically relevant to countries or regions within the African continent. The study design, geographic region/country, focus of research, and key findings were documented for each eligible article and summarized to illustrate the weight and research coverage in each area. Publications with more than one focus (e.g. secondary and tertiary prevention) were categorized by the primary emphasis of the paper. Research specific to HIV-infected women or focused on feasibility issues was delineated within each of the four public health categories.

RESULTS

A total of 380 research articles/reports were included. The majority (54.6 %) of cervical cancer research in Africa focused on secondary prevention (i.e., screening). The number of publication focusing on primary prevention (23.4 %), particularly HPV vaccination, increased significantly in the past decade. Research regarding the treatment of precancerous lesions and invasive cervical cancer is emerging (17.6 %), but infrastructure and feasibility challenges in many countries have impeded efforts to provide and evaluate treatment. Studies assessing aspects of quality of life among women living with cervical cancer are severely limited (4.1 %). Across all categories, 11.3 % of publications focused on cervical cancer among HIV-infected women, while 17.1 % focused on aspects of feasibility for cervical cancer control efforts.

CONCLUSIONS

Cervical cancer research in African countries has increased steadily over the past decade, but more is needed. Tertiary prevention (i.e. treatment of disease with effective medicine) and quality of life of cervical cancer survivors are two severely under-researched areas. Similarly, there are several countries in Africa with little to no research ever conducted on cervical cancer.

Knowledge of HPV among HIV-Infected and HIV-Uninfected Adolescent Women in South Africa

OBJECTIVE

The aim of this study is to examine the knowledge of human papillomavirus (HPV) and cervical cancer among HIV-infected and HIV-uninfected female adolescents in South Africa.

METHODS

Subjects were recruited from a parent study of HPV infection comprised of females ages 16-21 in Masiphumelele, Cape Town, South Africa. A total of 30 subjects, 15 HIV-infected and 15 HIV-uninfected, were selected via randomization and completed a measure of HPV knowledge, based on a previously validated instrument. The study took place in May 2013.

RESULTS

The overall mean score on the measure for all subjects was 43.3% (S.D. 10.9). There was no significant difference in HPV knowledge between the HIV-infected and HIV-uninfected groups. Based on results from a previous large-scale study using the same validated measure, this sample scored significantly worse on general HPV knowledge than samples from the US, UK, and Australia.

CONCLUSION

Given the limited knowledge of HPV in this sample, there is greater need for education about the prevention of cervical cancer, specifically among high-risk adolescent women.

Cervical cancer screening and HPV vaccine acceptability among rural and urban women in Kilimanjaro Region, Tanzania

OBJECTIVE

To determine cervical cancer screening coverage and the knowledge, attitudes and barriers toward screening tests among women in rural and urban areas of Tanzania, as well as explore how they view the acceptability of the HPV vaccine and potential barriers to vaccination.

SETTING

A cross-sectional study using interview-administered questionnaires was conducted using multistage random sampling within urban and rural areas in Kilimanjaro Region, Tanzania.

PARTICIPANTS

Women aged 18-55 were asked to participate in the survey. The overall response rate was 97.5%, with a final sample of 303 rural and 272 urban dwelling women.

PRIMARY AND SECONDARY OUTCOME MEASURES

Descriptive and simple test statistics were used to compare across rural and urban strata. Multivariate logistic regression models were used to estimate ORs and 95% CIs.

RESULTS

Most women (82%) reported they had heard of cervical cancer, while self-reported cervical cancer screening among women was very low (6%). In urban areas, factors associated with screening were: older age (OR=4.14, 95% CI 1.86 to 9.24 for ages 40-49, and OR=8.38, 95% CI 2.10 to 33.4 for >50 years), having health insurance (OR=4.15, 95% CI 1.52 to 11.4), and having knowledge about cervical cancer (OR=5.81, 95% CI 1.58 to 21.4). In contrast, among women residing in rural areas, only condom use (OR=6.44, 95% CI 1.12 to 37.1) was associated with screening. Women from both rural and urban areas had low vaccine-related knowledge; however, most indicated they would be highly accepting if it were readily available (93%).

CONCLUSIONS

The current proportion of women screened for cervical cancer is very low in Kilimanjaro Region, and our study has identified several modifiable factors that could be addressed to increase screening rates. Although best implemented concurrently, the availability of prophylactic vaccination for girls may provide an effective means of prevention if they are unable to access screening in the future.

HPV vaccine acceptability in Africa: a systematic review

OBJECTIVE

The objective of this study was to provide a systematic review of peer-reviewed literature on the factors associated with HPV vaccine acceptability among adults in African countries.

METHODS

A systematic search was conducted across five electronic databases: EMBASE, PsychINFO, CINAHL, Global Health and Ovid MEDLINE, to identify studies related to HPV vaccination acceptability in African countries (August 2013). The Health Belief Model was used to guide data abstraction and synthesis.

RESULTS

Fourteen unique studies representing ten sub-Saharan African countries were identified, with more than half published within the last two years. Acceptability of the HPV vaccine for daughters was high (range 59-100%); however, vaccine-related awareness and knowledge were low. Perceived barriers including accessibility and cost concerns were important for acceptance, as were cues to action from healthcare providers and governments.

CONCLUSIONS

This review suggests that acceptability of the HPV vaccine in countries in this region will be high. Broad knowledge gaps were highlighted regarding HPV and cervical cancer and these should be addressed. Education on the vaccine's effectiveness and reducing perceived barriers to vaccination would also be useful. Public endorsement by governments and healthcare providers will likely also increase acceptance.

Determinants of acceptance and subsequent uptake of the HPV vaccine in a cohort in Eldoret, Kenya

The development of Human Papillomavirus (HPV) vaccines provides new opportunities in the fight against cervical cancer. Many acceptability studies have revealed high interest in these vaccines, but acceptance is only a precursor of behavior, and many factors, at personal, community and provider level, may inhibit the translation of willingness to vaccinate into actual uptake. Through a longitudinal study in Eldoret, Kenya, HPV vaccine acceptability was measured before a vaccination program (n = 287) and vaccine uptake, as reported by mothers, once the program was finished (n = 256). In between baseline and follow-up, a pilot HPV vaccination program was implemented via the GARDASIL Access Program, in which parents could have their daughter vaccinated for free at the referral hospital. The program was promoted at schools: Health staff informed teachers who were then asked to inform students and parents. Even though baseline acceptance was very high (88.1%), only 31.1% of the women reported at follow-up that their daughter had been vaccinated. The vaccine was declined by 17.7%, while another 51.2% had wanted the vaccination but were obstructed by practical barriers. Being well-informed about the program and baseline awareness of cervical cancer were independently associated with vaccine uptake, while baseline acceptance was correlated in bivariate analysis. Side effects were of great concern, even among those whose daughter was vaccinated. Possible partner disapproval lowered acceptance at baseline, and women indeed reported at follow-up that they had encountered his opposition. In Kenya, women prove to be very willing to have their daughter vaccinated against cervical cancer. However, in this study, uptake was more determined by program awareness than by HPV vaccine acceptance. School-based vaccination might improve coverage since it reduces operational problems for parents. In addition, future HPV vaccination campaigns should address concerns about side effects, targeting men and women, given both their involvement in HPV vaccination decision-making.

Knowledge, attitudes and practices on adolescent vaccination among parents, teachers and adolescents in Africa: a systematic review protocol

BACKGROUND

Vaccines are the most successful and cost-effective public health interventions available to avert vaccine-preventable diseases and deaths. Despite progress in the field of adolescent health, many young people in Africa still get sick and die from vaccine-preventable diseases due to lack of vaccination. Parents, adolescents and teachers are key players with regard to implementation of adolescent vaccination policies. Therefore, understanding their knowledge, attitudes and practices towards adolescent vaccination may provide clues on what can be done to improve vaccine uptake among adolescents. The aim of this study is to conduct a qualitative and quantitative systematic review on knowledge, attitudes and practices on adolescent vaccination among parents, teachers and adolescents in Africa.

METHODS

We will include both quantitative and qualitative primary studies. Eligible quantitative studies include both intervention and observational studies. Qualitative studies to be included are focus group discussions, direct observations, in-depth interviews and case ethnographic studies. We will search PubMed, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, WHOLIS, Africa Wide and CINAHL for eligible studies with no time and language limits. We will also check reference lists of included studies for other eligible reports. Two authors will independently screen the search output, select studies and extract data, resolving discrepancies by consensus and discussion. We will analyse qualitative data using thematic analysis where applicable, and quantitative studies findings will be presented in a narrative synthesis form based on the outcomes.

DISCUSSION

The findings from this systematic review will guide the identification of gaps on knowledge, attitudes and practices among the key role players on adolescent vaccination. We anticipate that our findings will guide the development of adolescent-focused vaccination policy in Africa, which is virtually non-existent at present.

Preparing for human papillomavirus vaccine introduction in Kenya: implications from focus-group and interview discussions with caregivers and opinion leaders in Western Kenya

BACKGROUND

Cervical cancer claims the lives of 275,000 women each year; most of these deaths occur in low-or middle-income countries. In Kenya, cervical cancer is the leading cause of cancer-related mortality among women of reproductive age. Kenya's Ministry of Public Health and Sanitation has developed a comprehensive strategy to prevent cervical cancer, which includes plans for vaccinating preteen girls against human papillomavirus (HPV) by 2015. To identify HPV vaccine communication and mobilization needs, this research sought to understand HPV vaccine-related perceptions and concerns of male and female caregivers and community leaders in four rural communities of western Kenya.

METHODS

We conducted five focus groups with caregivers (n = 56) and 12 key-informant interviews with opinion leaders to explore cervical cancer-related knowledge, attitudes and beliefs, as well as acceptability of HPV vaccination for 9-12 year-old girls. Four researchers independently reviewed the data and developed codes based on questions in interview guides and topics that emerged organically, before comparing and reconciling results through a group consensus process.

RESULTS

Cervical cancer was not commonly recognized, though it was understood generally in terms of its symptoms. By association with cancer and genital/reproductive organs, cervical cancer was feared and stigmatized. Overall acceptability of a vaccine that prevents cervical cancer was high, so long as it was endorsed by trusted agencies and communities were sensitized first. Some concerns emerged related to vaccine safety (e.g., impact on fertility), program intent, and health equity.

CONCLUSION

For successful vaccine introduction in Kenya, there is a need for communication and mobilization efforts to raise cervical cancer awareness; prompt demand for vaccination; address health equity concerns and stigma; and minimize potential resistance. Visible endorsement by government leaders and community influencers can provide reassurance of the vaccine's safety, efficacy and benefits for girls and communities. Involvement of community leadership, parents and champions may also be critical for combatting stigma and making cervical cancer relevant to Kenyan communities. These findings underscore the need for adequate planning and resources for information, education and communication prior to vaccine introduction. Specific recommendations for communication and social-marketing strategies are made.

Cervical cancer prevention in Malawi: a qualitative study of women's perspectives

Researchers posit that cervical cancer knowledge is central to participation in prevention behaviors. However, of the many barriers to cervical cancer prevention in low- and middle-income countries, cervical cancer knowledge remains severely limited among communities at great risk for the disease. Malawi is one such country where the burden of cervical cancer is considerably high. Formative research targeting cervical cancer prevention is needed, particularly research that explores ways to deliver cervical cancer information efficiently and effectively to Malawian women. In this study, the authors aimed to garner Malawian women's understanding of cervical cancer and to shed light on preferences for health information delivery, including community health advocacy. Qualitative, in-depth interviews were conducted with 30 Malawian women and analyzed for recurring themes. In general, women had limited cervical cancer knowledge, which supported misperceptions about the disease, including factors pertaining to risk and prevention. Nonetheless, women reported that receiving cervical cancer information from trusted sources would help promote preventive behaviors. Women noted that they received most of their health information from hospital personnel, but distance was a barrier. Women also expressed interest in community health advocacy. Perspectives from Malawian women may be vital toward informing efforts to increase cervical cancer knowledge and prevention.

Acceptability of human papillomavirus vaccine: a survey among master of business administration students in KwaZulu-Natal, South Africa

Cervical cancer is a preventable public health problem. The two new human papillomavirus (HPV) vaccines are available but not accessible to everyone in South Africa, as they are very expensive. This study aimed to investigate educated peoples acceptability regarding HPV vaccination. This was a cross-sectional survey conducted among 146 master of business administration students by self-administered, anonymous questionnaire. The majority (74%) of the participants ever heard of cervical cancer, but only 26.2% heard about HPV. After reading the fact information regarding cervical cancer and HPV, the intention to vaccinate their daughters increased from 88% to 97.2% (P = 0.003). The majority (75.4%) indicated that HPV vaccination should be given before their daughters are mature enough to understand about sex, and 80.3% reported that they will discuss matters related to sex with their daughters if their daughters want to know about the vaccine. Those who did not want to vaccinate their daughters highlighted that they want more information regarding safety of the vaccine which might change their decision towards HPV vaccination. A health education information method can increase the vaccination acceptance rate in South Africa.

Cancer prevention in Africa: a review of the literature

Cancer is an emerging crisis in Africa. Cancer was the seventh leading cause of death in 2004. If not controlled, cancer incidence in Africa is expected to reach 1.28 million cases annually and claim 970,000 lives yearly by 2030. This paper presents a review of the literature on current cancer prevention approaches in Africa, and consists of cancer prevention studies conducted in African countries (e.g. South Africa and Nigeria) from PubMed, Scopus, and CINAHL databases. Common female cancers in Africa are breast and cervical cancer while prostate cancer is the most common neoplasm among African males. Other common cancers are liver, colorectal, and non-Hodgkin’s lymphoma. Mortality related to these cancers comes as a result of delays in screening and treatment, unfamiliarity with cancer and cancer prevention, inaccessibility and unaffordability of care, and inefficiency of healthcare systems. Cancer prevention efforts are deficient because many governments lack cancer prevention and control policies. Also contributing to the lack of cancer prevention and control policies are low levels of awareness, scarce human and financial resources, and inadequacy of cancer registries. Overall, governments grapple with limited funds and competing healthcare priorities. As cancer continues to increase in Africa, the need for rigorous interdisciplinary research on cancer etiology and monitoring in Africa has never been timelier. Cost-effective cancer prevention programs, coordination of donor funding, advocacy, and education should be aggressively pursued. The call for more collaborative approaches in research and policy is urgently needed.

Performance of 21 HPV vaccination programs implemented in low and middle-income countries, 2009-2013

BACKGROUND

Cervical cancer is the third most common cancer in women worldwide, with high incidence in lowest income countries. Vaccination against Human Papilloma Virus (HPV) may help to reduce the incidence of cervical cancer. The aim of the study was to analyze HPV vaccination programs performance implemented in low and middle-income countries.

METHODS

The Gardasil Access Program provides HPV vaccine at no cost to help national institutions gain experience implementing HPV vaccination. Data on vaccine delivery model, number of girls vaccinated, number of girls completing the three-dose campaign, duration of vaccination program, community involvement and sensitization strategies were collected from each program upon completion. Vaccine Uptake Rate (VUR) and Vaccine Adherence between the first and third doses (VA) rate were calculated. Multivariate linear regressions analyses were fitted.

RESULTS

Twenty-one programs were included in 14 low and middle-income countries. Managing institutions were non-governmental organizations (NGOs) (n = 8) or Ministries of Health (n = 13). Twelve programs were school-based, five were health clinic-based and four utilized a mixed model. A total of 217,786 girls received a full course of vaccination.Mean VUR was 88.7% (SD = 10.5) and VA was 90.8% (SD = 7.3). The mean total number of girls vaccinated per program-month was 2,426.8 (SD = 2,826.6) in school model, 335.1 (SD = 202.5) in the health clinic and 544.7 (SD = 369.2) in the mixed models (p = 0.15). Community involvement in the follow-up of girls participating in the vaccination campaign was significantly associated with VUR. Multivariate analyses identified school-based (β = 13.35, p = 0.001) and health clinic (β = 13.51, p = 0.03) models, NGO management (β = 14.58, p < 10(-3)) and duration of program vaccination (β = -1.37, p = 0.03) as significant factors associated with VUR.

CONCLUSION

School and health clinic-based models appeared as predictive factors for vaccination coverage, as was management by an NGO; program duration could play a role in the program's effectiveness. Results suggest that HPV vaccine campaigns tailored to meet the needs of communities can be effective. These results may be useful in the development of national HPV vaccination policies in low and middle-income countries.

The HPV vaccine: a comparison of focus groups conducted in South Africa and Ohio Appalachia

Worldwide, cervical cancer is one of the leading causes of morbidity and mortality among women. Even though women in developing countries account for approximately 85 % of the cervical cancer cases and deaths, disparities in cervical cancer rates are also documented in developed countries like the United States (U.S.). Recently, formative research conducted in the U.S. and developing countries like South Africa have sought to gain a better understanding of the knowledge, beliefs, and attitudes about cervical cancer prevention, HPV, and the acceptance of the HPV vaccine. This study compares findings from two independent focus group studies. One study was conducted in a segregated township in Johannesburg, South Africa (n = 24) and the other study was conducted in Ohio Appalachia (n = 19). The following seven themes emerged during the discussions from both studies: HPV and cervical cancer; health decision making; parent-child communication; healthy children; HPV vaccine costs; sexual abuse; and HPV vaccine education. Findings from both studies indicate the importance of the role of mothers and grandmothers in the health care decision-making process for children and a lack of awareness of HPV and its association with cervical cancer. While there was interest in the HPV vaccine, participants voiced concern about the vaccine's cost and side effects. Some participants expressed concern that receipt of the HPV vaccine may initiate adolescent sexual behavior. However, other participants suggested that the HPV vaccine may protect young women who may experience sexual abuse. The importance of developing culturally appropriate educational materials and programs about cervical cancer prevention and the HPV vaccine were expressed by participants in both countries.

Global evidence reaffirms the case for routine HPV and potential HIV adolescent vaccination in South Africa

ABSTRACT: 

The availability of two prophylactic HPV vaccines, coupled with a potential prophylactic HIV vaccine delivered to adolescents through a school-based sexual and reproductive health platform represents a potentially significant, potent long-term primary prevention strategy against two sexually transmitted infections: HPV and HIV infection within a highly susceptible group. South Africa has earmarked the re-engineering of school health services. This initiative ensures a ‘health presence in every school’ focused on developing a social, sexual and reproductive health platform within secondary schools addressing HIV/AIDS prevention, teenage pregnancies and social concerns such as drug abuse. Despite this opportunistic platform for HIV and HPV vaccines introduction among adolescents, much work remains to overcome existing ethical and financial and programmatic barriers.

A qualitative analysis of factors influencing HPV vaccine uptake in Soweto, South Africa among adolescents and their caregivers

BACKGROUND

In South Africa, the prevalence of oncogenic Human Papillomavirus (HPV) may be as high as 64%, and cervical cancer is the leading cause of cancer-related death among women. The development of efficacious prophylactic vaccines has provided an opportunity for primary prevention. Given the importance of psycho-social forces in vaccine uptake, we sought to elucidate factors influencing HPV vaccination among a sample of low-income South African adolescents receiving the vaccine for the first time in Soweto.

METHODS

The HPV vaccine was introduced to adolescents in low-income townships throughout South Africa as part of a nationwide trial to understand adolescent involvement in future vaccine research targeting human immunodeficiency virus (HIV). We performed in-depth semi-structured interviews with purposively-sampled adolescents and their care providers to understand what forces shaped HPV vaccine uptake. Interviews were recorded, transcribed, translated, and examined using thematic analysis.

RESULTS

Of 224 adolescents recruited, 201 initiated the vaccine; 192 (95.5%) received a second immunization; and 164 (81.6%) completed three doses. In our qualitative study of 39 adolescent-caregiver dyads, we found that factors driving vaccine uptake reflected a socio-cultural backdrop of high HIV endemnicity, sexual violence, poverty, and an abundance of female-headed households. Adolescents exercised a high level of autonomy and often initiated decision-making. Healthcare providers and peers provided support and guidance that was absent at home. The impact of the HIV epidemic on decision-making was substantial, leading participants to mistakenly conflate HPV and HIV.

CONCLUSIONS

In a setting of perceived rampant sexual violence and epidemic levels of HIV, adolescents and caregivers sought to decrease harm by seeking a vaccine targeting a sexually transmitted infection (STI). Despite careful consenting, there was confusion regarding the vaccine's target. Future interventions promoting STI vaccines will need to provide substantial information for participants, particularly adolescents who may exercise a significant level of autonomy in decision-making.

Knowledge about cervical cancer, pap test and barriers towards cervical screening of women in Turkey

We aimed to identify knowledge about cervical cancer (CC) and Pap test (PT) and the barriers why women do not have Pap test done. The study was conducted with a sample of 1,036 women. Overall, 64.4 % had heard of CC, 43.1 % had heard about PT and 24.7 % had had a test at least once. It was determined that women had moderate knowledge of cervical cancer but poor knowledge of Pap test. Knowledge of CC and PT was significantly better among employed and single women, who had higher education, no prior delivery, a higher income level and regular gynaecological examination. Common barriers to PT were lack of awareness, being uncomfortable with the procedure and not knowing where to go for a PT. Utilization of the PT will not increase unless knowledge is improved and barriers are eliminated. Healthcare professionals are the key persons to provide both knowledge and facilities towards the goal of CC prevention.

Barriers and facilitators to HPV vaccination: perspectives from Malawian women

The aim of this research was to elucidate potential barriers and facilitators to human papillomavirus (HPV) vaccination in Malawi, a sub-Saharan country. In Malawi, approximately 31 out of every 100,000 women develop cervical cancer annually, and 80% of those affected die from this malignancy. HPV vaccination may provide a feasible strategy for cervical cancer prevention in Malawi. However, important questions and concerns regarding cervical cancer and HPV vaccination acceptance among individuals and their communities must be considered prior to vaccine delivery. Qualitative interviews were conducted with 30 Malawian mothers aged 18-49 years from Chiradzulu District. Women's knowledge and beliefs about HPV, cervical cancer, and vaccination, and their social-ecological contexts were explored in-depth. Thematic analyses revealed that despite women's limited knowledge, cervical cancer was perceived to be a serious disease. Participants believed that as women, they were responsible for their children's health. Women unanimously reported that they would vaccinate their children against HPV, especially if a health professional recommended it. Malawi's health care infrastructure could present challenges to HPV vaccine programs; however, participants did not typically report this to be a barrier to vaccination. These data shed light on factors that may influence HPV vaccination acceptance and uptake in Malawi.

A qualitative study of HPV vaccine acceptability among health workers, teachers, parents, female pupils, and religious leaders in northwest Tanzania

BACKGROUND

As human papillomavirus (HPV) vaccines become available in developing countries, acceptability studies can help to better understand potential barriers and facilitators of HPV vaccination and guide immunisation programs.

METHODS

Prior to a cluster-randomised phase IV trial of HPV vaccination delivery strategies in Mwanza Region, Tanzania, qualitative research was conducted to assess attitudes and knowledge about cervical cancer and HPV, and acceptability of and potential barriers to HPV vaccination of Tanzanian primary schoolgirls. Semi-structured interviews (n=31) and group discussions (n=12) were conducted with a total of 169 respondents (parents, female pupils, teachers, health workers and religious leaders).

RESULTS

While participants had heard of cancer in general, most respondents had no knowledge of cervical cancer, HPV, or HPV vaccines. Only health workers had heard of cervical cancer but very few knew its cause or had any awareness about HPV vaccines. After participants were provided with information about cervical cancer and HPV vaccination, the majority stated that they would support HPV vaccination of their daughter to protect them against cervical cancer. Opt-out consent for vaccination was considered acceptable. Most preferred age-based vaccination, saying this would target more girls before sexual debut than class-based vaccination. Potential side effects and infertility concerns were raised by 5/14 of participating male teachers.

DISCUSSION

Reported acceptability of HPV vaccination amongst parents, teachers and other community members was high in this population. Respondents stressed the need to provide adequate information about the vaccine to parents, that also addresses side effects and infertility concerns.

Cervical human papillomavirus and HIV infection in women of child-bearing age in Abidjan, Côte d'Ivoire, 2010

Background:

We sought to document the association of Human immunodeficiency Virus (HIV) infection and immunodeficiency with oncogenic Human Papillomavirus (HPV) infection in women with no cervical neoplastic lesions identified through a cervical cancer screening programme in Côte d’Ivoire.

Methods:

A consecutive sample of women stratified on their HIV status and attending the national blood donor clinic or the closest HIV clinic was recruited during a cervical cancer screening programme based on the visual inspection. Diagnosis of HPV infection and genotype identification were based on the Linear Array; HPV test.

Results:

A total of 445 (254 HIV-positive and 191 HIV-negative) women were included. The prevalence of oncogenic HPV infection was 53.9% (95% confidence interval (CI) 47.9–59.9) in HIV-positive women and 33.7% (95% CI 27.1–40.3) in HIV-negative women (odds ratio (OR)=2.3 (95% CI 1.5–3.3)). In multivariate analysis, HIV-positive women with a CD4 count <200 cells mm³ or between 200 and 499 cells mm³ were more likely to harbour an oncogenic HPV compared with women with a CD4 count ⩾500 cells mm³ with OR of 2.8 (95% CI 1.1–8.1) and 1.7 (95% CI 1.0–2.9), respectively.

Conclusion:

A high prevalence of oncogenic HPV was found in women with no cervical neoplastic lesions, especially in HIV-positive women. Despite antiretroviral use, immunodeficiency was a main determinant of the presence of oncogenic HPV.

A cross-sectional study of HPV vaccine acceptability in Gaborone, Botswana

Background

Cervical cancer is the most common cancer among women in Botswana and elsewhere in Sub-Saharan Africa. We sought to examine whether HPV vaccine is acceptable among parents in Botswana, which recently licensed the vaccine to prevent cervical cancer.

Methods and Findings

We conducted a cross-sectional survey in 2009, around the time the vaccine was first licensed, with adults recruited in general medicine and HIV clinics in Gaborone, the capital of Botswana. Although only 9% (32/376) of respondents had heard of HPV vaccine prior to the survey, 88% (329/376) said they definitely will have their adolescent daughters receive HPV vaccine. Most respondents would get the vaccine for their daughters at a public or community clinic (42%) or a gynecology or obstetrician's office (39%), and 74% would get it for a daughter if it were available at her school. Respondents were more likely to say that they definitely will get HPV vaccine for their daughters if they had less education (OR = 0.20, 95% CI = 0.07–0.58) or lived more than 30 kilometers from the capital, Gaborone (OR = 2.29, 95% CI = 1.06–4.93). Other correlates of acceptability were expecting to be involved in the decision to get HPV vaccine, thinking the vaccine would be hard to obtain, and perceiving greater severity of HPV-related diseases.

Conclusions

HPV vaccination of adolescent girls would be highly acceptable if the vaccine became widely available to the daughters of healthcare seeking parents in Gaborone, Botswana. Potential HPV vaccination campaigns should provide more information about HPV and the vaccine as well as work to minimize barriers.

Parents’ anxieties about the risk of HIV/Aids for their Deaf and hard of hearing adolescents in South Africa: A qualitative study

Adolescents who are Deaf or hard of hearing may be vulnerable to HIV/AIDS. Adolescents’ open communication with parents encourages positive sexuality. The relationship between the Deaf adolescent and their parent could be obstructed by communication difficulties. This article explores parents’ anxieties about HIV risk. We interviewed nine parents of Deaf adolescents in South Africa. We explored their fears of the risk of HIV/AIDS for their children. Participants believed that their children were at risk of HIV infection. Although they did communicate with their children about sexuality and HIV/AIDS, some experienced communication difficulties. Communicative relationships between these adolescents and their parents should be encouraged.

Aspects of prophylactic vaccination against cervical cancer and other human papillomavirus-related cancers in developing countries

Cervical cancer and other human papillomavirus- (HPV-) related cancers are preventable, but preventive measures implemented in developing countries and especially in low-income rural regions have not been effective. Cervical cancer burden derived from sexually transmitted HPV infections is the heaviest in developing countries, and a dramatic increase in the number of cervical cancer cases is predicted, if no intervention is implemented in the near future. HPV vaccines offer an efficient way to prevent related cancers. Recently implemented school-based HPV vaccination demonstration programmes can help tackle the challenges linked with vaccine coverage, and access to vaccination and health services, but prevention strategies need to be modified according to regional characteristics. In urban regions WHO-recommended vaccination strategies might be enough to significantly reduce HPV-related disease burden, but in the rural regions additional vaccination strategies, vaccinating both sexes rather than only females when school attendance is the highest and applying a two-dose regime, need to be considered. From the point of view of both public health and ethics identification of the most effective prevention strategies is pivotal, especially when access to health services is limited. Considering cost-effectiveness versus justice further research on optional vaccination strategies is warranted.

Global challenges of implementing human papillomavirus vaccines

Human Papillomavirus vaccines are widely hailed as a sweeping pharmaceutical innovation for the universal benefit of all women. The implementation of the vaccines, however, is far from universal or equitable. Socio-economically marginalized women in emerging and developing, and many advanced economies alike, suffer a disproportionately large burden of cervical cancer. Despite the marketing of Human Papillomavirus vaccines as the solution to cervical cancer, the market authorization (licensing) of the vaccines has not translated into universal equitable access. Vaccine implementation for vulnerable girls and women faces multiple barriers that include high vaccine costs, inadequate delivery infrastructure, and lack of community engagement to generate awareness about cervical cancer and early screening tools. For Human Papillomavirus vaccines to work as a public health solution, the quality-assured delivery of cheaper vaccines must be integrated with strengthened capacity for community-based health education and screening.

Implementing HPV Vaccines: Public Knowledge, Attitudes, and the Need for Education

This article reviews qualitative research on public knowledge and attitudes to HPV vaccines, focusing on socio-economically challenged populations. Keyword searches were conducted on MEDLINE and ISI Web of Science for relevant peer-reviewed literature in English. A high acceptance of HPV vaccines was found despite low knowledge about HPV (types, prevalence, transmission, health risks, and cervical screening). Facilitators of HPV vaccine uptake included fear of cancer and desire to protect children's health. Barriers included low knowledge levels, perception of HPV vaccines as potential causes of sexual disinhibition, concerns about vaccine costs, social stigma, adverse effects, and parental unwillingness to permit vaccination of pre-adolescent children. Despite acceptance of HPV vaccines, implementation in low-resource settings faces social and economic difficulties. To pursue and strengthen cervical screening in these settings, public education about HPV is key.

HPV vaccine acceptability in Ghana, West Africa

OBJECTIVE

Cervical cancer is a leading cause of cancer-related mortality among women in Ghana. As of this writing no data are available concerning knowledge, attitudes and acceptability of human papillomavirus (HPV) vaccination by women in Ghana.

METHODS

Between November and December 2009, a self-administered survey was used to elicit information from 264 Ghanaian women, ages 18-65.

RESULTS

Overall, 40% had heard about HPV vaccine and 94% were willing to vaccinate themselves or their daughters. Ideal age for vaccination was 12.7 years. Most women (75%) thought the vaccine should be received regardless of one's number of sex partners. The most prevalent concerns were whether the vaccine would be administered safely using clean needles (82%), and possible future side effects (77%). Concerns about cost and vaccine encouraging earlier sex were reported by nearly half. Significant barriers to vaccine acceptance were women's lack of knowledge about the gravity of cervical cancer in Ghana and utility of Pap test in detecting it, low perceived risk for cervical cancer, low social support to vaccine use, and low self-efficacy to find a doctor or clinic to get vaccinated (p<05). About 55% of the women did not know the vaccine only works among those who are not yet infected with HPV. Schools and television were the most preferred methods of educating the public and cervical cancer prevention ranked as the ideal message (80%). Most respondents believed the decision to vaccinate their daughter should be made by both parents (34%) or in conjunction with the daughter (37%), as opposed to the government (17%).

CONCLUSIONS

Educational programs addressing specific barriers identified in the current study have the potential to significantly improve HPV vaccine uptake in Ghana.

Eurogin 2010 roadmap on cervical cancer prevention

The EUROGIN 2010 roadmap represents a continuing effort to provide and interpret updated information on cervical cancer screening and vaccination against the cause of the disease, high-risk human papillomavirus (HPV). Contrary to the two previous reports in 2008 and 2009, the present roadmap gives equal room to HPV-based screening and HPV vaccination, as a result of the recent strengthening of the evidence on the efficacy and feasibility of both approaches. The superiority of HPV testing in primary screening compared to cytology (in more developed countries) and to cytology or visual inspection methods (in less developed countries) has been demonstrated in several randomised trials. High vaccine efficacy has been confirmed up to 7 years after vaccination; school-based programmes in some countries have been able to reach over 70% coverage among adolescent girls. Demonstration projects have indicated that the delivery of HPV vaccines in less developed countries is feasible and favourably received by populations where cervical cancer is very common. HPV-based screening can diminish cervical cancer incidence more quickly than HPV vaccination, but vaccination can eventually facilitate screening efforts, especially if new vaccines against a greater number of HPV types are introduced. The availability of two highly complementary prevention tools such as HPV testing and HPV vaccination makes it possible to conceive integrated strategies for the elimination of cervical cancer that have no precedent in the cancer field. HPV tests and HPV vaccines remain, however, too expensive, and large-scale financing of screening and vaccination in less developed countries is sorely lacking.

Is routine human papillomavirus vaccination an option for ghana?

Cervical cancer remains an important public health problem in developing countries where over 80% of the global burden occurs annually but screening has been ineffective. In a polygamous country like Ghana with a high incidence of cervical cancer but no national screening program, the Human Papilloma Virus (HPV) vaccine presents a unique opportunity to reduce the burden of HPV infection and cervical cancer in Ghanaian women. The evidence so far indicates that the vaccines are safe and efficacious. Although routine HPV vaccination of girls raises several religious, political, socioeconomic and ethical challenges, the emphasis of this paper will be on addressing the ethical challenges using the principles of autonomy, beneficence, non-maleficence and justice as a framework. Parental autonomy can be preserved with judicious exemptions for those who decline the vaccine on religious and philosophical grounds. This promotes public health without trampling parental authority. Routine HPV vaccination confers several benefits to individuals and society by preventing HPV infection. Instead of causing harm; it reduces harm by preventing the development of about 70% of cervical cancers and removing the negative physical and psychological impact of a cervical cancer diagnosis. It also has the potential to reduce the disparities in cervical cancer rates and its cost effectiveness will ensure considerable cost savings in terms of the money spent on diagnosis and treatment. Consequently, the HPV vaccine is an important public health landmark and achievement in women's health that must be heralded, especially in developing countries where the bulk of the disease and death occur.
