Impact of interventions to improve HPV vaccination acceptance and uptake in school-based programs: Findings of a pilot project in Quebec

ContextVaccination coverage against human papillomavirus (HPV) in school-based programs in Quebec, Canada, is suboptimal despite more than a decade of introduction. Three interventions to improve HPV vaccine acceptability and coverage in school-based programs were developed, implemented as part of a multicomponent strategy and evaluated. MethodSixty-four (64) schools were recruited, of which 32 received the interventions (pilot schools), and 32 received usual vaccination activities (control schools). Two approaches were used to assess the impact of the interventions. Pre-post questionnaires were completed by parents in both pilot and control schools. Quantitative analyses of vaccination coverage using the Quebec immunization registry were conducted. ResultsParticipating parents (n = 989 in the pre-intervention survey and n = 772 in the post-intervention one) were generally aware of HPV and HPV vaccination. Most parents were confident about vaccination, had little or no hesitation and had decided to have their child vaccinated. Parents in the pilot schools were less concerned about vaccine safety than those in the control schools after the interventions. Parents in the pilot schools were also more likely to have decided to have their child vaccinated. A statistically significant difference of 7.4 % in HPV vaccine coverage between pilot and control schools was observed (82.9 % vs 75.5 %, p = <0.0001). ConclusionAlthough school-based programs offer equitable access to vaccination and minimize access barriers, it remains crucial to identify effective interventions to improve vaccine uptake further and reach the WHO cervical cancer elimination goal. Our multicomponent strategy appears to have positively impacted HPV vaccine acceptability and coverage and could be adapted to other contexts where vaccination is delivered in school-based programs.

Providing parents with HPV vaccine information from a male perspective may render them more inclined to have their daughters vaccinated

ObjectivesSeveral high-income countries have implemented a gender-neutral vaccination program against human papillomavirus (HPV) infections. The impact of a gender-neutral program (GNP) on parental intention to vaccinate their daughters has not been studied, especially in countries with low HPV vaccine coverage among girls Patients and methodsIn July 2019, before a GNP was implemented in France (2021), the French National Cancer Institute (INCa) conducted a survey on HPV vaccine acceptance among parents of children aged 11–19 years living in France. In the sample of girls’ parents (n = 1424 parents, 1726 girls), we investigated whether parents who declared no initial intention to have their daughter(s) vaccinated changed their minds after reading information including a male perspective on HPV consisting in description of HPV-related disease among men and in ascertainment of the fact that in some countries, the HPV vaccine is recommended for boys, after which they were once again asked about their intentions “if the vaccine were recommended to boys and girls alike”. ResultsAs regards 295 (25.7 %) of the 1147 unvaccinated girls, their parents declared no intention to have them vaccinated, while 509 (44.4 %) were not sure. Among the parents of the 804 girls whose parents had not intended to have them vaccinated, 134 (16.7 %) changed their minds after reading about HPV among men. Fathers were more likely than mothers to change their minds, and finally intend to have their daughters vaccinated (adjusted relative risk, 1.74 [95 % confidence interval, 1.20,2.54]). ConclusionsThese results suggest that parents, and fathers in particular, could be more motivated to have their daughters vaccinated against HPV if the information with which they were provided included a male perspective and a recommendation of vaccination for boys as well as girls.

Knowledge and perception of HPV vaccination among Lebanese mothers of children between nine and 17 years old

BackgroundThe human papillomavirus (HPV), a prevalent sexually transmitted infection, is linked to a wide range of diseases, with cervical cancer being the most common and serious one. HPV vaccination is crucial for preventing cervical cancer and other HPV-related problems. The low acceptability of HPV vaccination among teenagers globally is largely due to a lack of understanding and information about HPV among parents. Our study aimed to evaluate the level of knowledge, attitude, intention, and HPV vaccination among parents in Lebanon as well as the variables influencing Lebanese mothers' intentions to vaccinate their children.MethodsA cross-sectional survey-based study involving 392 participants was conducted between May and June 2022. The study assessed parents' intention to vaccinate their children against HPV, their knowledge about HPV, and the HPV vaccine. The data was collected through an anonymous electronic questionnaire. A bivariate analysis was conducted using Student t-test and ANOVA to examine the relationship between the dependent variable “Intention to vaccination” and the secondary variables. The level of statistical significance was set at 0.05 for all data.ResultsOur findings showed that only 63% of the 392 participants claimed they would give their child the HPV vaccination. A positive significant association was demonstrated between "Intention to vaccinate against HPV" and mother's nationality, father's educational level, family income per month, information received about the HPV vaccine, parents' HPV vaccination, insurance coverage of the HPV vaccine, children's vaccinations with all required vaccines, knowledge of HPV, and knowledge of the HPV vaccine. Furthermore, when parents know about HPV, their desire to vaccinate their child increases by a factor of 1.832 times, and by 1.207 times when their knowledge level increases by one point.ConclusionThe majority of parents lacked a general understanding of most HPV-related statements, which highlights the requirement for educational interventions to raise parental awareness, understanding, and attitudes toward HPV and, as a result, increase parental acceptance of vaccinating their children. To increase the vaccination rate among adolescents, government authorities should ensure that the HPV vaccine is available in all hospitals and clinics and should be provided free of charge.

Knowledge and Attitudes of Human Papillomavirus (HPV) Vaccination among Secondary School Students in Selangor, Malaysia

Cervical cancer is a significant cause of female mortality in Malaysia, primarily linked to Human Papillomavirus (HPV) infection. To address this, the Malaysian government launched a HPV vaccination program targeting secondary school students. This study aimed to investigate the level of knowledge and attitude toward HPV vaccination and its association with demographics as a determinant among Malaysian secondary school students. A survey study using random sampling was conducted for 182 secondary school students in Selangor between the aged 13-17 years old. A validated questionnaire was used to collect data on demographics, knowledge, and attitudes toward HPV vaccination. The students demonstrated moderate knowledge (M=3.75, SD=.85) and generally positive attitudes (M=3.48, SD=3.57) towards HPV vaccination. Gender (χ2=6.39, p=.011), ethnicity (χ2=6.57, p=.037), religion (χ2=15.51, p=.004), and age (χ2=12.61, p=.013) were statistically significant factors affecting knowledge. Gender (χ2=8.44, p=.004) and family income (χ2=11.63, p=.040) significantly influenced attitudes. The Malaysian national HPV immunisation program has been effective, but improvements are needed. These include adopting a gender-neutral approach, educating parents to foster positive attitudes, and promoting acceptance of HPV vaccination. Strategies like introducing sexual education and collaboration with the Ministry of Health School Health Unit (UKS) are vital for enhancing public awareness and understanding of HPV vaccination.

Human Papillomavirus Vaccine Awareness and Acceptability for Primary Prevention of Cervical Cancer in Pakistan: A Cross-Sectional Study.

Human papillomavirus (HPV) vaccine is the most effective option for primary prevention HPV, a well-known cause of cervical cancer. The objective of the study was to assess awareness of HPV, the acceptability of its vaccine and factors associated with the acceptability among the adult population in Pakistan. A cross-sectional survey was conducted among adult population of Pakistan from January 2022 and March 2022. Due to the ongoing COVID-19 pandemic, instead of face-to-face interviews, a self-administered questionnaire was developed and distributed through Google Forms. The questionnaire was available in both English and Urdu languages to cater to a diverse population. Overall, 313 (65.2 %) study participants had heard about HPV infection, while 297 (61.9%) knew HPV as the cause of genital warts and 256 (53.3 %) knew that HPV can cause any type of cancer, with a higher percentage of awareness among those who were in any health care setting compared to those who were in a non-healthcare setting. Regarding the acceptability to get HPV vaccine, 320 (66.7%) of the study participants were willing to get vaccinated, while only 15(3.1%) of the study population had previously received HPV vaccine. The most important factors associated with HPV vaccine acceptability were younger age of 18-25 years (Prevalence Ratio (PR) =1.60, 95% Confidence Interval (CI) =1.11, 2.32), and 26-35 years (PR= 1.65, 95% CI=1.09, 2.50). HPV vaccine acceptability was also associated with working in a healthcare setting due to better awareness of HPV vaccine (PR= 1.29, 95% CI=1.03, 1.62). It is important to address the knowledge gaps existing in the community about HPV vaccine acceptability and barriers against it for the successful rollout of the HPV vaccination program in Pakistan. Mass awareness campaigns about HPV, HPV vaccine, and cervical cancer are needed to increase the acceptability of HPV vaccine among public at the time of reintroducing HPV vaccine.

Complex interplay of science reasoning and vaccine hesitancy among parents in Shanghai, China

The psychosocial underpinnings of vaccine hesitancy are complex. Research is needed to pinpoint the exact reasons why people hesitate to vaccinate themselves or their children against vaccine-preventable diseases. One possible reason are concerns that arise from a misunderstanding of vaccine science. We examined the impact of scientific reasoning on vaccine hesitancy and human papillomavirus (HPV) vaccination intent through a cross-sectional study of parents of vaccine-eligible children (N = 399) at immunization clinics in Shanghai, China. We assessed the relationship between science reasoning and both vaccine hesitancy and HPV vaccine acceptance using general additive models. We found a significant association between scientific reasoning and education level, with those with less than a high school education having a significantly lower scientific reasoning that those with a college education (ß = -1.31, p-value = 0.002). However, there was little evidence of a relationship between scientific reasoning and vaccine hesitancy. Scientific reasoning therefore appears not to exert primary influence on the formation of vaccine attitudes among the respondents surveyed. We suggest that research on vaccine hesitancy continues working to identify the styles of reasoning parents engage in when determining whether or not to vaccinate their children. This research could inform the development and implementation of tailored vaccination campaigns.

Exploring human papillomavirus vaccine hesitancy among college students and the potential of virtual reality technology to increase vaccine acceptance: a mixed-methods study.

Human papillomavirus (HPV) can cause cancers in men and women. Despite the availability of an effective vaccine, HPV vaccination coverage remains suboptimal among college students. Literature showed that hesitancy for HPV vaccination is a leading barrier to the uptake in this group. However, prior interventions have shown limitations in reducing HPV vaccine hesitancy in college students. Thus, this study examined a conventional educational approach using a vaccine information statement (VIS), and subsequently explored college students' HPV vaccine hesitancy and the potential of virtual reality (VR) technology to overcoming the limitations of interventional efforts. We employed a mixed-methods design along with convenience sampling, constituting a one-way pre- and post-intervention (HPV VIS) survey (Study A) and individual interviews (Study B). All data collections occurred with 44 college students at an urban public university at the mid-south region of the U.S. between October 2022 and April 2023. Study A assessed changes in HPV vaccination outcomes including knowledge, beliefs/attitudes, vaccine hesitancy, and intentions. Study B measured college students' primary reasons for HPV vaccine hesitancy and preferred strategies for the vaccination promotion including VR-based education. We conducted paired t-test and Wilcoxon signed ranks test for quantitative data and framework analysis for qualitative data. Participants reported significant improvements in knowledge [t(43) = 6.68, p < 0.001] regarding HPV vaccination between before and after reading the HPV VIS. No change was observed in beliefs/attitudes, vaccine hesitancy, and intentions. The framework analysis revealed college students' reasons for HPV vaccine hesitancy, needed information, and preferred strategies along with the potential of VR technology for future HPV vaccination education. The findings provided essential information on designing HPV vaccination information focused on vaccine hesitancy among college students. Future research should consider these findings in developing interventions including VR to increasing HPV vaccine acceptance among college students.

Parental Knowledge of HPV Infection, Cervical Cancer and the Acceptance of HPV Vaccination for their Children in Jos, Nigeria.

Despite the high prevalence of human papillomavirus (HPV) infections and cervical cancer in Nigeria, the utilization of the HPV vaccine as a highly effective preventive measure remains low. The aim of this study was to find out if parental knowledge of HPV infection and cervical cancer influenced the acceptance of HPV vaccines for their 9-14-year-old children. This was a cross-sectional survey of 509 parents comprising 262 fathers and 247 mothers in 8 randomly selected communities in Jos, Plateau State Nigeria. A pretested semi-structured investigator-administered questionnaire, without identifiers, was used to collect information on parental knowledge of HPV, cervical cancer, HPV vaccine and its acceptance for their 9-14-year-old children. The data were analysed using SPSS version 23.0. Bivariate analysis was done using chi-square statistical test. Point estimates with corresponding 95% confidence interval (CI) were estimated with a value of P ≤ 0.05 was considered as statistically significant. Five hundred and nine parents were interviewed. The mean age of the respondents was 43.7 ± 9.43 years. Most of the participants (86.1%) had formal education from primary to tertiary level. Only 1.60%, 11.60% and 1.62% of respondents had knowledge of HPV, cervical cancer and HPV vaccines respectively, whereas 67.8% of parents were willing to pay for the cancer-preventing HPV vaccines out-of-pocket. There was no statistically significant associations between parental level of education (P = 0.056), parental knowledge of cancer of cervix (P = 0.483), religion of parents (P = 0.324) and the acceptance of HPV vaccination for their children. There was a statistically significant association between parental willingness to pay for HPV vaccines if not offered free (P = 0.001) with acceptance of vaccination. Vaccine acceptability was associated with positive attitude towards the vaccine (odds ratio [OR] = 4.178; 95% CI, 1.714-10.180; P = 0.002), whereas parental knowledge of HPV, cervical cancer and HPV vaccine did not show significant association with acceptability of HPV vaccination for their children. Despite poor parental knowledge of HPV infection and cervical cancer, there was high acceptability of HPV vaccination for their children. HPV vaccination was acceptable to parents regardless of educational level or religion. Parents in Jos communities seems to have much faith in preventive vaccines as advertised by the health authorities. Accordingly, efforts should be geared towards ensuring availability, affordability and the provision of basic information regarding HPV vaccination in Northern Nigeria.

Determinants of Human Papillomavirus Vaccine Acceptance among Caregivers in Nigeria: A Fogg Behavior Model-Based Approach.

Human papillomavirus (HPV) vaccine uptake among adolescent girls is critical to reducing the burden of HPV-related cancers in Nigeria. This study assesses the factors influencing caregivers' acceptance of HPV vaccination for their charges, using the Fogg Behavior Model (FBM) as a theoretical framework. We analyzed cross-sectional data from 1429 caregivers of girls aged 9-17 in six Nigerian states, using a survey instrument based on the FBM. Participants were recruited via Facebook and Instagram advertisements and interviewed through Facebook Messenger in August and September 2023. The study received ethical clearance from Nigeria's National Health Research Ethics Committee. We applied bivariate and multivariate analyses to assess the relationships between the caregiver's perception of how likely their adolescent girl was to get vaccinated in the next 12 months and motivation, ability, social factors (such as discussions with family and friends), injunctive norms, previous COVID-19 vaccination, and respondents' sociodemographic characteristics. Adjusted odds ratios derived from logistic regression analyses revealed that caregivers' motivation and ability, as well as social factors, were significantly associated with their perception that the adolescent girl in their care would get vaccinated within the next 12 months. Our findings suggest that behavioral interventions tailored to enhance motivation, ability, and social support among caregivers could significantly increase HPV vaccine uptake among adolescent girls in Nigeria.

Educational Interventions Planned to Increase Human Papillomavirus Vaccination Acceptance among Adolescents and Their Parents in Asia: A Systematic Literature Review

Abstract One of the Global strategies to accelerate the elimination of cervical cancer is vaccinated with HPV vaccines by age 15 years by 2030. Recent studies showed that increased vaccine-related knowledge associated with HPV-vaccine acceptance and intention to vaccinate. In other words, insufficient information is the main barriers to vaccination acceptance. Accordingly, interventions that improve understanding of HPV vaccines may increase HPV vaccination coverage. The aim of this study was to summarize educational interventions designed to increase HPV vaccine acceptance in adolescents and their parents. We searched the databases of PubMed, Science Direct and Google Scholar on October-December 2020. We performed a literature search for published articles in English and searched relevant keywords (papillomavirus vaccines and knowledge, acceptance, intervention studies, communication, education). Our search was limited to studies targeting populations from Asian countries. Thirteen interventional studies performed in Asian countries met the inclusion criteria. Five studies used PowerPoint presentation and slide presentation as an educational intervention. Two studies applied written media that was an educational sheet that provided information on HPV vaccines. Two studies used social media and mobile for educational intervention. Two studies designed the educational intervention in 30 minutes and 1 hour lecture which following by question and answer. Two of studies conducted two educational interventions. First one was applied PowerPoint presentation and social media and the second one used lecture and group discussion. HPV vaccine acceptance is varied widely between studies across Asian countries. Increasing public awareness about HPV vaccines, will increase acceptance. Increasing acceptance, will lead to demand people for health policy makers to will introduce HPV vaccines into their national immunization program.

Acceptance of the Human Papillomavirus Vaccine among General Men and Men with a Same-Sex Orientation and Its Influencing Factors: A Systematic Review and Meta-Analysis.

The human papillomavirus (HPV) vaccine reduces the prevalence of genital warts and the cancers they are associated with in males. However, the vaccination of males has always been neglected. Here, we performed a meta-analysis to comprehend the acceptability of the HPV vaccine in men and the factors impacting vaccination intentions. We searched PubMed, Web of Science, Embase, Ovid, CNKI, and Wan Fang up to 5 July 2023 for studies that reported HPV vaccine acceptance among men. A random effects model was used to obtain the pooled acceptance rate, and subgroup analysis was performed. Then, the influencing factors of HPV vaccination in males were analyzed. A total of 57 studies with 32,962 samples were included in the analysis. The overall acceptance rate of the HPV vaccine in general men was 47.04% (95% confidence interval [95%CI]: 39.23-54.93%), and 62.23% (95% CI: 52.93-71.10%) among those whose sexual orientation contained men. HPV vaccine acceptance rates differed significantly between the two populations (p = 0.01). The population with a medical background (46.23%, 95% CI: 40.28-52.24%) was more willing to be vaccinated. In comparison to the employed population (66.93%, 95% CI: 48.79-82.81%) and the unemployed (68.44%, 95% CI: 52.82-82.23%), vaccination acceptance rates were lower among students (47.35%, 95% CI: 37.00-57.81%) (p = 0.04). The most significant barriers to vaccination were perceived low risk of infection for themselves (45.91%, 95% CI: 31.73-60.43%), followed by vaccine cost (43.46%, 95% CI: 31.20-56.13%). Moreover, the recommendations from medical professionals (60.90%, 95%CI: 44.23-76.37%) and sexual partners (60.09%, 95%CI: 27.11-88.67%) were significant factors in promoting vaccination. Overall, acceptance of the HPV vaccine among general men was at a lower level, despite being slightly higher among men with a same-sex orientation. Popularizing knowledge about diseases and vaccines, encouraging medical professionals to recommend vaccines to men, or reducing the cost of vaccines may promote HPV vaccination.

Knowledge of HPV and HPV Vaccination among Polish Students from Medical and Non-Medical Universities.

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

The Acceptability of Pharmacy-Based HPV Vaccination in Western Kenya among Pharmacy Clients and Providers.

Vaccine coverage for the human papillomavirus (HPV) remains low globally, and differentiated models of vaccine delivery are needed to expand access. Pharmacy-based models of the HPV vaccination may engage women who could benefit. We assessed the acceptability of such a model among pharmacy clients and providers at 20 private pharmacies in Kisumu County, Kenya. In questionnaires, participants (≥18 years) were asked the extent they agreed (5-point scale) with statements that assessed different acceptability component constructs outlined in the Theoretical Framework of Acceptability (TFA). From March to June 2022, 1500 pharmacy clients and 40 providers were enrolled and completed questionnaires. Most clients liked the intervention (TFA: affective attitude; 96%, 1435/1500) and did not think it would be hard to obtain (TFA: burden; 93%, 1399/1500). All providers agreed the intervention could reduce HPV infection (TFA: perceived effectiveness) and felt confident they could deliver it (TFA: self-efficacy). Among the clients who had received or were planning to receive the HPV vaccine in the future, half (50%, 178/358) preferred a pharmacy-based HPV vaccination. In this study, most Kenyan pharmacy clients and providers perceived a pharmacy-delivered HPV vaccination as highly acceptable; however, more research is needed to test the feasibility and effectiveness of this novel vaccine delivery model in Africa.

Abstract A043: Trusted sources of human papillomavirus (HPV) vaccine information in Mexican American parents: A cross-sectional study

Abstract Human papillomavirus (HPV) infection is associated with many types of cancers that disproportionately impact Hispanics. Mortality is 20% higher in Hispanic women than non-Hispanic white women who have cervical cancer. Hispanic men are 4x times more likely to have HPV-associated oropharyngeal cancer than women (9,100 cases vs. 2,000 cases, respectively) and Hispanic males have higher rates of HPV-associated penile cancer than non-Hispanics. An HPV vaccine exists that can prevent 90% of HPV-associated cancers; however, HPV vaccination rates have declined by approximately 75% in adolescents during the pandemic. The purpose of this study was to identify trusted sources of HPV vaccine information in Hispanics of Mexican American origin. A cross-sectional study design with an online survey was used to collect data from Mexican American parents of children 11-17 years of age. Two hundred and twenty-five parents (M age = 38.30, SD = 7.30) who identified predominately as female (83.1%) were included in the study. Over a third (39.1%, n = 88) of the participants reported to have three or more children and most of the sample (68%; n =153) reported to have vaccinated at least one of their children with the HPV vaccine. When participants were asked who they trust to provide information about the HPV vaccine, the top five trusted sources of HPV vaccine information were medical doctors (94.7%), registered nurses (52%), the Centers for Disease Control and Prevention (47.1%), the World Health Organization (43.1%), and pharmacists (25.3%). The least trusted sources of HPV vaccine information were the president of the U.S. (7.6%) and religious leaders (2.7%). Linear regression models revealed that HPV vaccine acceptance was associated with trusting registered nurses (p &amp;lt; .001) and the Centers for Disease and Control (p = .014) for recommending the HPV vaccine. Lastly, we examined the association between family-held beliefs about vaccines and personal beliefs about vaccines. Correlations ranged from -.28 to .72. The strongest correlation was between having a family with negative feelings about vaccines while growing up and believing that vaccines can cause serious illness (r = 0.72; p &amp;lt; .001). Importantly, the family-held belief that vaccines cause autism was strongly correlated with personal beliefs that vaccines cause autism (r = 0.56; p &amp;lt; .001). Several important findings emerged in the current study highlighting the importance of having trusted sources of HPV vaccine information to promote the HPV vaccine. Our findings have implications for designing health communications and interventions that incorporate trusted sources of HPV vaccine information to promote the HPV vaccine in Mexican American families.  Citation Format: Gabriel A.

A survey of potential acceptance of 9-valent HPV vaccine among Chinese male college students

ABSTRACT Human papillomavirus (HPV) has a great impact on world health. Vaccination is among the most important methods of preventing HPV infection. This study investigated Chinese male college students’ knowledge of, attitude toward, and acceptance of the 9vHPV vaccine and the independent predictors. An online cross-sectional study was conducted among male college students at Chinese colleges and universities from March 12 to March 23, 2022. Based on a literature review of similar studies, a self-questionnaire was designed to investigate the students’ knowledge of, attitude toward, and acceptance of the 9vHPV vaccine. Multivariate logistic regression analysis was performed to identify factors influencing their willingness to be vaccinated. In addition, the structural equation model was constructed. A total of 1,547 male college students completed the survey. Of all the students, 54.95% were unwilling to receive a 9vHPV vaccination, while only 45.05% expressed willingness. Multivariate logistic regression analysis revealed that the male college students willing to receive the vaccine included medical students, those in a romantic relationship, those whose relatives and friends had cervical cancer, those whose relatives and friends had received the 9vHPV vaccine, those supportive of promoting the vaccine for men, and those who would recommend the vaccine to their relatives and friends. Male college students exhibited high hesitancy toward the 9vHPV vaccine. Acceptance of the 9vHPV vaccine by male college students can be improved by deepening their accurate understanding of the vaccine and enhancing their positive attitude toward it.

Implementing the free HPV vaccination for adolescent girls aged below 14 in Shenzhen, Guangdong Province of China: experience, challenges, and lessons

Cervical cancer is a major public health concern in China, accounting for almost one-fifth of the global incidence and mortality. The recently prequalified domestic bivalent human papillomavirus (HPV) vaccine offers a practical and feasible preventive measure. In response to the global call for action, the National Health Commission issued an Action Plan to eliminate cervical cancer by 2030, with promotion of the HPV vaccination for school-aged girls as a critical step. Despite this, implementation of the vaccination has been patchy, with very low coverage among eligible girls. To address this, from December 2021 to December 2022, a demonstration project was launched in Shenzhen, Guangdong Province, to promote the inclusion of HPV vaccine in local immunisation programme and to address existing barriers to implementation. Using multiple sources of data, this article presents a case study of the demonstration project, analysing its impact on rolling out HPV vaccination among eligible girls and identifying any challenges encountered during implementation. The demonstration project has shown promising results in increasing the HPV vaccination rate, promoting public awareness and acceptance of the domestic HPV vaccine, and establishing a model for quickly scaling up the vaccination at the municipal level. The success of the project can be attributed to several factors, including strong governmental commitment, sufficient funding, multi-sectoral collaboration, ensured vaccine accessibility and affordability, improved vaccination services, and effective health education and communication strategies. Lessons learned from Shenzhen can provide valuable insights for future advocacy and implementation of the vaccination in other areas of China, but challenges must be addressed to achieve universal coverage. These include addressing vaccine hesitancy, expanding the programme to cover a broader age range, and ensuring consistent quality of vaccination services in primary care facilities. Overcoming these challenges will require innovative strategies, public-private partnerships, and sustained funding and resources. Future research should focus on evaluating the long-term effectiveness of the vaccination programme and identifying contextual factors that may impact its implementation in different settings. Overall, the effective control of cervical cancer in China will rely on the “political will” to ensure the incorporation of preventive interventions into policies and universal programme coverage.

Human Papillomavirus Vaccine Acceptance (HPV-VA) and Vaccine Uptake (HPV-VU): assessing the impact of theory, culture, and trusted sources of information in a Hispanic community

BackgroundHuman papillomavirus (HPV) is the most common sexually transmitted infection and is associated with many types of cancers that disproportionately impact Hispanics. An HPV vaccine is available for individuals ages 9—45 that can prevent up to 90% of HPV-associated cancers. The current study investigates factors associated with accepting the HPV vaccine in a predominately Hispanic community.MethodsA cross-sectional study design with an online questionnaire was used to collect data from a community sample of adults between the ages 18–65 residing in a U.S./Mexico border city, El Paso, Texas. Theory-based factors (e.g., the Health Belief Model), culture-based factors (e.g., familism), and trusted sources of information were examined as predictors of HPV-vaccine acceptance (HPV-VA) and HPV-vaccine uptake (HPV-VU).ResultsCommunity members (N = 602, Mage = 34.65, SD = 9.79) who were predominately Hispanic (89.4%) and female (79.6%) participated in the study. Linear regression models revealed that HPV-VA was associated with household size, primary language, engagement in organizational activities, health-related community stigma, government trust, and the HBM theory-based factors: perceived benefits, perceived harm, and perceived severity. Logistic regression analyses revealed that HPV-VU was associated with household size, engagement in non-organizational activities, HPV trusted sources of information, and perceived safety.ConclusionsAdequate HPV vaccination uptake among all vaccine-eligible Hispanics is an important step to lessen the HPV-attributed cancer burden. Our hypothesis that theory-based factors would be associated with HPV-VA and HPV-VU was supported. Our findings have implications for designing trusted, theory-based, and culturally sensitive health communications and interventions to promote vaccines in minority underrepresented communities.

"When you get the HPV vaccine, it will prevent cervical cancer; it will act as a shield": adolescent girls' knowledge and perceptions regarding the human papillomavirus vaccine in Zambia.

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

Bangladeshi parents’ knowledge and awareness about cervical cancer and willingness to vaccinate female family members against human papilloma virus: a cross sectional study

Background: Cervical cancer (CC) is an important cause of cancer death among Bangladeshi women and human papillomavirus (HPV) is the causative factor for developing CC. HPV vaccination is yet to be implemented as part of national immunization programme in Bangladesh. Method: The objective of this cross-sectional research was to evaluate the understanding of CC, HPV, and the willingness to accept HPV vaccination among parents of school-aged children (between 5-16 years) from grades 1-10 in the capital city of Bangladesh, Dhaka. The study was conducted from February 2020 to January 2021 by paper-based survey. Results: This study showed 86.6% of participants knew that CC is preventable and 98.6% knew that vaccine can prevent CC. Only 1.3% of the participants heard about HPV. Majority (97.1%) were interested in HPV vaccination to female family members. Knowledge about visual inspection with acetic acid (VIA) test, CC prevention and HPV vaccine were significantly associated with willingness to give vaccine. Gender, age, educational level and socioeconomic condition of respondents have no relation with vaccine acceptance (p&gt;0.05). This study showed that total 1319 (45%) respondents sought the vaccine free of cost and personal relation as friends and family were major source of information (64.8%). Conclusions: The study's results revealed that a significant number of Bangladeshi parents were aware of CC, CC prevention, and HPV vaccination. Nonetheless, most participants expressed a willingness to vaccinate their female family members against HPV.
