Akande OW, Akande TM. Human Papillomavirus Vaccination amongst Students in a Tertiary Institution in North Central Nigeria: A Cross-sectional Study on Sociodemographic Factors Associated with Its Awareness, Uptake and Willingness to Pay. Niger Postgrad Med J 2024; 31:14-24. [PMID: 38321793 DOI: 10.4103/npmj.npmj_265_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Accepted: 01/19/2024] [Indexed: 02/08/2024]
Abstract
BACKGROUND Human papillomavirus (HPV) vaccine is effective in averting 70%-90% of all HPV-related diseases. The assessment of its awareness, uptake and willingness to pay (WTP) is important in Nigeria which is one of the developing countries where more than three-quarter of the global burden of HPV-related diseases occur. This study aimed to determine the sociodemographic factors associated with the awareness, uptake and WTP for HPV vaccine amongst undergraduates in a tertiary institution in North Central Nigeria. METHODS This was a cross-sectional study. Data were collected from randomly sampled respondents through a validated self-administered questionnaire. Descriptive statistics, Chi-square and logistic regression analyses were applied to data collected to determine the awareness, uptake and WTP for HPV vaccine and their association with sociodemographic factors. The results of inferential statistics were considered significant when P < 0.05. RESULTS A total of 240 respondents were recruited, 15.4% of the respondents had heard about HPV vaccine, 2.1% of them had received at least a dose of the vaccine, 0.4% of them had completed three doses and 35.0% of them were willing to pay for it. Marital status (adjusted odds ratio [AOR]: 10.2; 95% confidence interval [CI]: 2.840-36.635) and parity (AOR: 5.8; 95% CI: 2.314-14.565) were predictors of WTP for the HPV vaccine. CONCLUSION The evidence generated from this study suggests that there is a need to increase the awareness and uptake of the vaccine at the individual and population levels. The recent introduction of the HPV vaccine is a laudable step towards improving vaccine uptake. Public health authorities at the local, state and national levels should be empowered to develop tailored vaccine demand creation and advocacy strategies for HPV vaccine. Males should also be involved in the advocacy strategies and research on HPV vaccine.

Nguyen NTT, Nguyen LH, Nguyen TT, Vu LG, Vu TMT, Le Vu MN, Vu GT, Latkin CA, Ho CSH, Ho RCM. Preference and willingness to pay for reproductive health services among adults in Urban-Rural transition settings of a developing country: evidence from a cross-sectional study in a rural district of Hanoi, Vietnam. BMC Health Serv Res 2023; 23:1196. [PMID: 37919709 PMCID: PMC10623698 DOI: 10.1186/s12913-023-10207-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 10/24/2023] [Indexed: 11/04/2023] Open
Abstract
BACKGROUND Since the introduction of fee-for-service models in public hospitals and the legalization of private health services in Vietnam in 1989, the price of reproductive health services has risen. These changes have exacerbated inequities in accessing reproductive health services. This study examines potential disparities in willingness to pay for reproductive health services among adults in a rural district of Hanoi. METHODS A cross-sectional study was conducted at 9 communes in Thanh Oai district, a rural district of Hanoi, Vietnam, in July 2019. Face-to-face interviews were conducted using a structured questionnaire to collect self-reported data. The contingent valuation was used to examine willingness to pay for reproductive health services with a starting price of 2 million VND (~ US$86.2, July 2019 exchange rate), which is the average price of all RHS in public facilities in Vietnam. Multiple Logistic regression and Multiple Interval regression models were used to identify factors associated with willingness to pay and the amount that people were willing to pay for reproductive health services. RESULTS Among 883 participants, this study found 59.1% of them willing to pay for reproductive health services at an average maximum amount of US$36.2, significantly less than the current average price of US$86.2. Occupation, number of sex partners, perception towards the necessity of reproductive health services, and prior use of reproductive health services were found to significantly influence willingness to pay for reproductive health services, while age, income level, gender, occupation, perception towards the necessity of reproductive health services and prior use of reproductive health services were reportedly correlated with the amount participants were willing to pay for reproductive health services. CONCLUSION Lower willingness to pay for reproductive health services compared to the current prices (US$36.2 vs. US$86.2) is likely related to an overall low awareness of the necessity of reproductive health services, and future education campaigns should specifically target those from lower-income backgrounds. Financial subsidization should also be provided, especially for those from the low-income group, to ensure equitable access to reproductive health services. Given the heterogeneity of reproductive health services, further studies should examine the willingness to pay for each type of service independently.

Willingness to pay for hepatitis B virus vaccine and associated factors among households in Bahir Dar City, northwest Ethiopia: using contingent valuation method. Front Public Health 2023; 11:1058026. [PMID: 37475766 PMCID: PMC10354278 DOI: 10.3389/fpubh.2023.1058026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 06/19/2023] [Indexed: 07/22/2023] Open
Abstract
Background The prevention of disease burden and death through vaccination is one of the most cost-effective methods. Even though the Hepatitis B Virus (HBV) has significant public health problems in Ethiopia, there is no compulsory HBV vaccination program for adults and the vaccine's market value was not yet estimated in the Ethiopia context. Therefore, this study aimed to assess the willingness to pay (WTP) for the HBV vaccine and its associated factors among households in Bahir Dar City, northwest Ethiopia. Methods A cross-sectional study was conducted among 620 households from March 1 to 30, 2020. A systematic random sampling technique was employed to select the required number of households. An interviewer-administered questionnaire was used to collect the necessary information. The contingent valuation method was conducted to measure WTP for the HBV vaccine. A Tobit regression model was employed to investigate significantly associated factors, and variables with a p-value of <0.05 were considered statistically significant. Results In this study, 62.17% of households were willing to pay for the HBV vaccine with an average cost of ETB174.24 (US$5.25). Male household heads (P = 0.014), favorable attitude (P = 0.017), and good knowledge (P < 0.001) toward the vaccine were positively associated with WTP, whereas age (P < 0.001), single marital status (P = 0.012) and divorced/widowed (P = 0.018) marital status were negatively associated with WTP. Conclusions Overall, most households were willing to pay for the HBV vaccine with an average demand of ETB174.24 (US$5.25). Therefore, a national-level HBV vaccine strategy should be designed considering the households' willingness to pay. In addition, working on attitudes and knowledge toward the vaccine could potentially increase the household's willingness to pay for the HBV vaccine.

[PMID: 37307254 DOI: 10.1371/journal.pone.0286924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 05/26/2023] [Indexed: 06/14/2023] Open
Abstract
Hand foot and mouth disease (HFMD) is a notifiable viral disease in Malaysia, and is transmitted primarily among young children. Although vaccines for enteroviruses 71 (EV-71) were approved in China against HFMD, the availability and the acceptance of the vaccine in the Malaysia are unknown. This study investigated and ascertained the determinants of willingness-to-pay (WTP) for HFMD vaccination in Selangor Malaysia. This study adopted a cross-sectional, contingent valuation method involving 390 parents of young children aged six and below. The double bounded dichotomous choice (DBDC) approach was employed to assess the WTP for HFMD vaccine among respondents. A bivariate probit model was used to assess the key determinants of WTP for HFMD vaccine, while the mean WTP was measured using the Krinsky and Robb procedure. We found that 279 (71.5%) of parents were willing to pay for the HFMD vaccination. The estimated single bounded mean WTP was MYR460.23 (equivalent to US$ 102.17) for two doses of HFMD vaccination. The double bounded analysis revealed that the vaccine's price, poor education background and lower income were the key factors that significantly affected the WTP, with the estimated mean WTP being MYR394.00 (US$ 87.47). In conclusion, most Malaysian parents are willing to pay for the HFMD vaccination. The estimated WTP identifies the optimal price point for HFMD vaccination in Malaysia. Furthermore, the government should focus on an awareness programme for the HFMD vaccination among parents who have lower income or education level.

Abstract
BACKGROUND Human papillomavirus (HPV) is responsible for most cervical cancer cases globally, with women living with HIV having a higher risk of persistent HPV infection and HPV-associated disease. The HPV vaccine is a promising tool to reduce cervical cancer rates, but its uptake among women living with HIV in Nigeria is unknown. METHODS A facility-based, cross-sectional survey was conducted with 1371 women living with HIV to assess their knowledge of HPV, cervical cancer, and the HPV vaccine as well as their willingness to pay for the vaccine at the HIV treatment clinic at the Nigerian Institute of Medical Research, Lagos. To identify factors associated with the willingness to pay for the HPV vaccine, multivariable logistic regression models were developed. RESULTS This study found that 79.1% of participants had not heard of the vaccine, and only 29.0% knew its efficacy in preventing cervical cancer. In addition, 68.3% of participants were unwilling to pay for the vaccine, and the average amount they were willing to pay was low. Knowledge of HPV, the HPV vaccine, and cervical cancer and income were factors associated with the willingness to pay for the vaccine. Health workers were the primary source of information. CONCLUSIONS This study highlights the lack of knowledge and low willingness to pay for the HPV vaccine among women living with HIV in Nigeria and emphasizes the importance of improving education and awareness. Factors associated with the willingness to pay, such as income and knowledge, were identified. Practical strategies, such as community outreach and school-based education programs, could be developed to increase vaccine uptake. Further research is needed to explore additional factors influencing the willingness to pay.

Abstract
INTRODUCTION Stated preference studies are a valuable tool to elicit respondents' willingness to pay (WTP) for goods or services, especially in situations where no market valuation exists. Contingent valuation (CV) is a widely used approach among stated-preference techniques for eliciting WTP if prices do not exist or do not reflect actual costs, for example, when services are covered by insurance. This review aimed to provide an overview of relevant factors determining WTP for health services to support variable selection. METHODS A comprehensive systematic literature search and review of CV studies assessing determinants of WTP for health services was conducted, including 11 electronic databases. Two of the authors made independent decisions on the eligibility of studies. We extracted all determinants used and related p values for the effect sizes (e.g. reported in regression models with WTP for a health service as outcome variable). Determinants were summarised in systematic evidence tables and structured by thematic domains. RESULTS We identified 2082 publications, of which 202 full texts were checked for eligibility. We included 62 publications on 61 studies in the review. Across all studies, we identified 22 WTP determinants and other factors from 5 thematic domains: sociodemographic characteristics, perceived threat, perceived benefit, perceived barriers, and other information. CONCLUSION Our review provides evidence on 22 relevant determinants of WTP for health services, which may be used for variable selection and as guidance for planning CV surveys. Endogeneity should be carefully considered before interpreting these determinants as causal factors and potential intervention targets.

Abstract
BACKGROUND Human papillomavirus (HPV) is the most common cause of cervical cancer among Saudi females in reproductive age. Parents' awareness of and attitude toward vaccination against HPV in young females are very crucial to prevent the development of cervical cancer. This study aimed to assess the knowledge of and attitude toward the HPV vaccine among Saudi parents in the Saudi western region. METHODS An analytical cross-sectional questionnaire-based study was conducted that included 343 parents randomly selected from in the Saudi western region. The online questionnaire was disseminated via WhatsApp and Telegram groups of parents in schools and among visitors of parents in primary health care. RESULTS The studied parents had poor knowledge of HPV and its vaccine. About a third (32.9%) knew about the HPV vaccine and the most common source of their knowledge was physicians (38%) while the most frequent barrier for vaccination was their confidence of being not at risk (75.2%). About 90.0% of parents having a good level of knowledge were willing to vaccinate their children. CONCLUSION This study reveals a poor level of knowledge about HPV infection and its vaccine among both male and female parents in the Saudi Arabian western area. As a consequence, only 7.2% of them had vaccinated their female children. The majority of the parents having good knowledge about the HPV vaccine were willing to vaccinate their children. Therefore, this study highlights the necessity of educating women on cervical cancer risk factors, as well as the importance of screening programs.

Abstract
Background Payment methods for human papillomavirus (HPV) vaccine could substantially influence vaccination behavior. In China, HPV vaccination uptake remains currently low. This study aims to determine willingness to pay (WTP) for HPV vaccines among Chinese female health care workers under different payment scenarios. Methods This is a nationwide online survey recruiting female health care workers aged 18–45 years from 31 provinces throughout China. We collected the respondents’ vaccination status of HPV vaccines and their sociodemographics. Two WTPs were defined and estimated in the study. A general WTP for HPV vaccination was determined using the contingent valuation method with double dichotomous choice bidding. A WTP out-of-pocket was estimated for each HPV vaccine under two scenarios, including partial coverage by governmental subsidy or partial incorporation in basic medical insurance. Accordingly, a multivariable linear regression model was employed to determine the association between sociodemographis and general WTP. Then the maximum WTP out-of-pocket was compared among the respondents’ attitude shift towards HPV vaccination, payment scenarios, and levels of vaccine attributes, using non-parametric Kruskal-Wallis test. Results A total of 15,969 respondents were included in the study. The median general WTP was 2000 CNY (interquartile range, 1000–3200 CNY), positively associated with younger age, unmarried status, higher monthly income, fewer children, more positive vaccination behavior, working in tertiary hospital, higher local GDP and HDI (each P < 0.05). Moreover, the median WTP out-of-pocket was 1250 CNY (540–2000 CNY). It was significantly higher for vaccines partly covered by governmental subsidy (median, 1250 CNY; interquartile range, 560–2000 CNY), imported vaccines (1260 CNY; 630–1960 CNY), and 9-valent vaccines (1400 CNY; 750–2240 CNY) (each P < 0.001). Additionally, majority of respondents did not change their attitude towards HPV vaccination between two payment scenarios; those remaining with more expensive HPV vaccines (51.1%) had higher WTP out-of-pocket (1400 CNY; 560–2250 CNY) than those with cheaper vaccines (39.0%) (1120 CNY; 490–1960 CNY) (P < 0.001). Conclusion Chinese female health care workers have high WTP for HPV vaccines. A direct public funding for HPV vaccination is more preferable. Our findings may facilitate the adjustment of HPV vaccination strategy and payment mechanism in China.

Resource mobilization for tetanus vaccination in Vietnam: Uptake, demand and willingness to pay among women of reproductive age. Front Public Health 2022; 10:980850. [PMID: 36330125 PMCID: PMC9623147 DOI: 10.3389/fpubh.2022.980850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Accepted: 08/22/2022] [Indexed: 01/25/2023] Open
Abstract
Introduction Tetanus vaccine coverage in Vietnam has been declining in recent years due to a rapid population growth rate, shrinking budget, and inefficient resource mobilization strategy. This study examined the uptake, demand, and willingness to pay (WTP) for tetanus vaccines in Vietnamese women of reproductive age as well as determined associated factors and assessed the feasibility of the long-term tetanus vaccine resource mobilization scheme. Methods Cross-sectional data were obtained on 807 women of childbearing age in Hanoi, Vietnam in 2016. Tetanus vaccine uptake, demand, and willingness to pay were collected by using a structured questionnaire. Multivariable logistic and interval regression models were used to examine associated factors with vaccine uptake, demand, and WTP. Results Of 807 participants, 42.4 and 64.8% had sufficient tetanus vaccination (i.e., received at least three doses of vaccine) and were willing to pay for tetanus vaccination. The mean amount of WTP for one dose of tetanus was US$ 7.3 (95% CI = 6.7-7.9). Having children or being aware that the tetanus vaccine was free-of-charge were negatively associated with WTP for tetanus vaccine. Having a high school education, living in a rural area, and not being aware of vaccine prices or being aware that vaccines were provided freely reduced the amount of WTP. WTP increased among women receiving information from friends and relatives. Conclusion Despite of exemption from the tetanus vaccination programs, this study indicated a low tetanus vaccination coverage and a moderate degree of WTP for tetanus vaccine among Vietnamese women of childbearing age. Target-specific educational and financial support interventions, along with efforts to reduce vaccination costs are critical to improving the vaccine uptake, demand, and WTP for tetanus immunization among women.

Abstract
Background: Cervical cancer is the fifth most deadly cancer in women in Iran. The present study aimed to investigate the monetary value of cervical cancer screening benefits from a social perspective. Methods: A cross-sectional study was conducted among 480 women aged 30 to 59 years in Mazandaran province, Iran, from 2020-21. The willingness to pay (WTP) for screening tests- Pap smear and simultaneous tests- was investigated using a researcher-made questionnaire based on the contingent valuation method (CVM) in 2 separate sample groups. The first group received basic information regarding cervical cancer (Scenario 1), while the second received complementary information in addition to basic knowledge (Scenario 2). Multivariate regression was applied to examine factors affecting WTP and the difference between the mean WTP in 2 scenarios was analyzed by a t-test. Results: The mean WTP of Pap smear and simultaneous tests was estimated at US$135.08 and US$160.19, respectively. There were significant and negative relationships between age and household size with the WTP of the Pap smear test. The number of people with income, household expenses, a chronic illness, and suggested base price indicated significant and positive effects on WTP of the Pap smear test. The number of people with income and household expenses showed significant and positive relationships with the WTP of simultaneous tests. There was no significant difference between the mean WTP of each group and the demand for screening tests was not elastic. Conclusion: The mean WTP of screening tests is notable when compared to their cost, demonstrating the need of concentrating on screening programs.

Abstract
Human papillomavirus (HPV) vaccine offers protection of between 80 and 100% for anogenital warts and 60-80% in reducing the incidence of pre-malignant lesions from cervical cancer. However, uptake remains low in Nigeria among adolescent girls. This study was a qualitative study that assessed mothers' acceptability and concerns regarding uptake of HPV vaccine by their adolescent daughters. In-depth interviews were conducted with 20 mothers of adolescents girls aged 9-15 years. A snowballing sampling technique was adopted to select the mothers within the community. Consent was obtained for the use of audiotapes, which were transcribed verbatim with thematic analysis of data. Mothers were between the ages of 30-49 years and most of them were traders. Almost all of the women have heard about cervical cancer, but their knowledge about cervical cancer and HPV vaccine was low. Despite their low knowledge, most of the mothers accepted that the vaccine is good and was willing for their adolescent daughters to take the HPV vaccine for the prevention of HPV. However, cost of the vaccine, side effects, and potential exposure of their daughters to promiscuity after taking the vaccine for protection were the major concerns expressed by the mothers as regards to HPV vaccine uptake by their daughters. Findings highlight the need for health promotion and education programs about cervical cancer, HPV, and HPV vaccine to increase awareness and knowledge among mothers of adolescent girls. Also, HPV vaccination should be included as part of routine immunization for female adolescents.

Abstract
Human papilloma virus (HPV) vaccine for adolescents was recommended as an effective prevention strategy of HPV-related cancers. In Vietnam, HPV vaccination has not been introduced to male adolescent. This study was conducted to examine the acceptance of having boys vaccinated against HPV and its underlying reasoning, and to identify their parent's willingness to pay (WTP) for HPV vaccination in central Vietnam. 785 parents of boys were directly interviewed based on a structured questionnaire. Parent's acceptability of HPV vaccine for their sons was identified by one question with response on 3-point scale (agree, don't know, and disagree). Multivariate logistic regression model was used to determine contributing factors to participant's acceptance. Bidding game method was applied to elicit WTP values for HPV vaccination with initial bid of 161.2 USD. The results showed that 49.2% of parents agreed to have their sons vaccinated against HPV. Factors that influenced parent's acceptance including son's age older than 12 years (OR = 1.5; 95% CI: 1.08-1.98); being eldest son (OR = 1.6; 95% CI: 1.13-2.19), being mother (OR = 1.4; 95% CI: 1.01-1.91), parents with high educational level (OR = 1.7; 95% CI: 1.11-2.47) and their knowledge of HPV and HPV vaccine (OR = 1.8; 95% CI: 1.23-2.65). Average WTP value for full doses of HPV vaccine was 137.5 USD, ranging between 9 USD and 188.3 USD. Parents' knowledge of HPV and HPV vaccine was the only factor affecting WTP value (Rho: 0.11; p-value: 0.030). The findings suggest a strategy be introduced for HPV vaccination to male adolescents in Vietnam.

Abstract
Industrial workers are a vulnerable population for HIV and sexually transmitted infections (STIs). This cross-sectional study assessed the general knowledge about sexually transmitted infections (STIs) and HIV transmission risk among 289 industrial workers in Northern Vietnam. Results indicated that most workers could identify common routes of HIV transmissions and were aware of common STIs. However, insufficient knowledge about HIV transmission via anal sex practices, as well as common signs and symptoms of STIs were observed. Gender, marital status, education, locality status and health information sources were associated with the knowledge. This study reveals a gap of knowledge about HIV and other STIs, and suggested further tailored education interventions to improve the knowledge and promote sexual health-seeking behaviors in industrial workers.

Abstract
BACKGROUND Adolescents are prone to Sexually Transmitted Diseases (STDs) such as Human Papilloma Virus (HPV). Although HPV is a preventable disease, the vaccination rate is low. As parents should vaccinate their children to prevent HPV, the goal of this study was to identify the factors related to mother's intention to vaccinate adolescents against HPV. MATERIALS AND METHODS This cross-sectional study was performed in Qazvin from 2019 to 2020. The participants included 126 literate mothers who had a daughter between 12 and 14 years and health system information registry. To collect the data, a questionnaire was made based on the educational model of behavioral intent. Parents were interviewed in person in health centers or via phone at home. Data were analyzed using Spearman's correlation. RESULTS The mean (SD) age of the mothers, fathers, and girls were 39.60 (6.18), 43.51 (7.58), 13 (0.82) years, respectively. They hadn't received education regarding HPV. The mean (SD) of the knowledge, attitude, and HPV vaccination intention scores were 27.77 (18.08), 67.38 (10.25), and 15.44 (18.44), respectively. The factors related to HPV vaccination intention were parents' knowledge (r = 0.29, p = 0.001), positive attitude (r = 0.22, p = 0.010), parents' education (r = 0.22, p = 0.050) and family income (r = 0.21, p = 0.010). CONCLUSIONS The high cost of vaccines, economic problems, and lack of knowledge were strong limitations for HPV vaccination. Thus, health workers should have informed parents and teens of the benefits of HPV vaccination. This process should be supported by policy makers.

Abstract
Background: The Willingness to pay (WTP) for and acceptance of cervical cancer prevention (CCP) methods have an important role in the control of this type of cancer. Therefore, the aim of this study was to estimate the WTP and acceptance of CCP methods with the contingent valuation method (CVM). Methods: In this systematic review and meta-analysis study, the required information was collected by searching relevant keywords in PubMed, Scopus, Embase, Web of Knowledge, and their Persian equivalent in the Scientific Information Database (SID) and Elmnet databases during January 1, 2000 to June 30, 2020. All studies that reported the WTP and CCP methods with the CVM in English or Persian were included. The reporting quality of studies was assessed by strengthening the Reporting of Observational Studies in Epidemiology (STROBE). Comprehensive meta-analysis (CMA: 2) software was used to conduct the meta-analysis. The content analysis method was used for qualitative data analysis. Results: Finally, 28 articles (with 49610 people) were included in the study. Most of the participants were women (35.7%). The HPV vaccine was the most common method of prevention (75%). The overall acceptance rate was 64% and the overall positive WTP rate was 66%. The average WTP was US$30.44, which accounts for about 0.84% of GDP per capita. The most significant effective factors included income, age, education, high-risk sexual behaviors, and awareness of cervical cancer, belief in the risk of cervical cancer, and belief about the effectiveness of prevention methods. The cost was the most important reason for the unwillingness to pay and accept. Conclusion: Results show that the WTP and acceptance rate of CCP methods are relatively high. It is recommended to reduce the cost of prevention methods, especially the HPV vaccine, and to increase awareness and improve the attitude of people. Also, it is recommended to consider other methods of estimation of WTP and other cancers in future studies.

Abstract
The relative importance for serious side effects was the highest among all attributes. Mothers express more WTP for the quadrivalent vaccine compared to bivalent due to its protection against genital warts. Quadrivalent vaccination could be the most suitable candidate for implementation in the national immunization schedule.
This study aimed to identify mothers’ preferences and willingness-to-pay (WTP) for human papillomavirus (HPV) vaccines (in this case, bivalent and quadrivalent) in Iran. We used a discrete choice experiment (DCE) method to present mothers with choices between two hypothetical profiles of vaccines, described by combinations of five attributes, each with two or three levels. We analyzed the DCE results using conditional logistic regression and measured WTP estimates for each attribute. Our response rate was 53.96%, while the completion rate for questioner was 93.57%. We identified protection against cervical cancer, protection against genital warts, protection duration, serious side effects, and cost to influence mothers’ preferences for HPV vaccination. The relative importance for serious side effects was the highest among all attributes. Mothers’ WTP for bivalent and quadrivalent HPV vaccines was in US $ −432 (US $1 = IRR 42,000) and US $ 380, respectively. Quadrivalent vaccination could be the most suitable candidate for implementing the national immunization schedule. The reason is that mothers express more WTP for the quadrivalent vaccine than bivalent due to its protection against genital warts.

Abstract
Objectives Vaccines are recognized as the most effective strategy for long-term prevention of coronavirus disease 2019 (COVID-19) because they can reduce morbidity and mortality. The purpose of the present study was to evaluate willingness to pay (WTP) for a future COVID-19 vaccination among young adults in Southern Vietnam. Methods A cross-sectional, descriptive, and analytic study was undertaken with data collected from a community-based survey in southern Vietnam for 2 weeks in May 2020. The contingent valuation method was used to estimate WTP for COVID-19 vaccine. The average amount that respondents were willing to pay for the vaccine was US$ 85.9 2 ± 69.01. Results We also found the differences in WTP according to sex, living area, monthly income, and the level of self-rated risk of COVID-19. Conclusion Our findings possibly contribute to the implementation of a pricing policy when the COVID-19 vaccine is introduced in Vietnam.

Abstract
BACKGROUND The proportion of incident cases of HPV-attributable cancers is highest in the low- and middle-income countries (LMICs) but many are yet to initiate HPV vaccination programs. This meta-analysis was performed to assess the uptake of HPV vaccination in LMICs at the beginning of the global strategy to eliminate cervical cancer and describes the gaps and challenges. METHODS A systematic search was conducted in PubMed, EMBASE, Scopus, Web of Science, and CENTRAL databases for observational studies that reported the uptake of HPV vaccination until October 2020. The meta-analysis was done using a random-effects model to assess the pooled estimate of HPV uptake. CRD42021218429. FINDINGS During 2008-2020, an estimated 3.3 million females received at least one dose of HPV vaccine with 61.69% of the target population vaccinated. In countries with high uptake, the pooled estimate of uptake was higher in females than males (45.48% vs 8.45%) and showed significant decline in 2015-2020 compared to 2006-2014 (89.03% vs 41.48%). In countries with low uptake, the estimate of uptake was low in both males and females (5.31% vs 2.93%) and showed increase in uptake in 2015-2020 compared to 2006-2014 (0.76% vs 5.22%). In countries with high uptake, compared to routine programs, the estimate was higher when delivered through demonstration programs (89.94% vs 59.74%). INTERPRETATION The major concern was a significant drop in the uptake in countries that started with high uptake, challenges in the maintenance of vaccine uptake, sustainability of funding and the lack of standard monitoring and reporting.

Abstract
Introduction: Cervical cancer is the second leading cause of cancer death among Vietnamese females. By detecting precancerous cells, Pap test screening plays a critical role in the fight against cervical cancer. The present study aims to investigate health-related factors associated with receipt of Pap test among Vietnamese females living in rural Vietnam, particularly examining the correlation between awareness level of the Pap test and the receiving of Pap test. Methods: Anderson’s Behavioral Model of Health Services Use was utilized as the present study’s theoretical framework. A self-administrated questionnaire was completed among 193 females residing in Quantri City, Vietnam. Results: Only 15.5% (N=30) of participants in our sample have had a Pap test. Pap test awareness (OR = 18.38, p<.001) was a strong predictor of Pap test receipt. Participants who had heard about Pap test were 18.38 times more likely to take a Pap test compared to those who had no prior knowledge. Besides the awareness, variables including employment (OR = .18, p<.05), and health insurance coverage (OR = 10.75, p<.05) were significantly associated with Pap test uptake. Conclusion: Findings from the present study suggests interventions should be provided through public health efforts to enhance awareness of Pap test by aiming at increasing primary prevention of cervical cancer, especially among Vietnamese women living in rural areas, in order to reduce cancer health disparities.

The critical question that needs to be addressed is whether HCWs are willing to accept and purchase this vaccine. The objective of this study was to evaluate the acceptance and willingness to pay (WTP) for the vaccine among HCWs. METHODS From May to July 2019, a cross-sectional study was conducted among registered general practitioners (GPs) in Indonesia. A contingent valuation method was employed to evaluate the WTP. Besides acceptance and WTP, various explanatory variables were also collected and assessed. A logistic regression and a multivariable linear regression were used to explore the explanatory variables influencing acceptance and WTP, respectively. RESULTS Among 407 respondents, 391 (96.0%) expressed acceptance of a free vaccination. The mean and median WTP was US$ 37.0(95%CI:US$ 32.76-US$ 41.23) and US$ 17.90(95%CI:US$ 17.90-US$ 17.90), respectively. In an unadjusted analysis, those 30 years old or younger had 2.94 times greater odds of vaccine acceptance compared to those who were older (95%CI: 1.07-8.08). Location of alma mater, type of workplace, length of individual medical experience, and monthly income of GPs were all significantly associated with WTP. CONCLUSION Although the vast majority of GPs would accept a freely provided vaccine, they were also somewhat price sensitive. This finding indicates that partial subsidy maybe required to achieve high vaccine coverage, particularly among GPs at community health centres or those with a shorter duration of medical practice.

Cancer Manag Res 2020; 12:8519-8526. [PMID: 32982444 PMCID: PMC7502398 DOI: 10.2147/cmar.s275038] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Accepted: 09/07/2020] [Indexed: 01/29/2023] Open
Abstract
Background Cervical cancer is one of the profound threats to women’s lives and the fourth most common cancer among women. Ethiopia launched the human papilloma vaccination for the first time, with the support of the Global Alliance for Vaccine and Immunization (GAVI) in 2018. Therefore, the aim of this study was to assess the acceptability of the human papillomavirus vaccine and associated factors among parents of daughters in Gondar town, Northwest Ethiopia. Methods A community-based cross-sectional study with a total sample of 946 study participants was conducted in Gondar town from April to May 2019. The study participants were selected using a multistage sampling technique from parents having a daughter of 9−17 years age. Data were collected using an interviewer-administered questionnaire. The data were entered into EpiData version 4.2 and exported to STATA version 14 for analysis. Variables having a p-value of <0.2 and <0.05 in the bivariable and multivariable logistic regression were considered as a statistically significant factor for the acceptance of HPV vaccination. Results A total of 899 study participants with a response rate of 95% were included in the study. Among participants in this study, 81.3% with 95% CI (78.6, 83.7) accepted to vaccinate their daughters for HPV vaccination. The acceptance to vaccinate daughters for HPV vaccination was affected by being from the richest household [AOR= 3.44, 95% CI = (1.97, 6.01)], good knowledge about cervical cancer [AOR=5.49, 95% CI= (2.62, 11.52)], and positive attitude towards HPV vaccination [AOR=21.53, 95% CI= (11.60, 39.96)]. Conclusion The study revealed that the acceptance to human papillomavirus vaccination is high and was significantly associated with the level of knowledge about cervical cancer, the attitude towards HPV vaccination, and the wealth status of the households. Therefore, community education on cervical cancer and its prevention is crucial to increase awareness and acceptance as well.

Risk Manag Healthc Policy 2020; 13:989-997. [PMID: 32801973 PMCID: PMC7413698 DOI: 10.2147/rmhp.s243048] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Accepted: 06/25/2020] [Indexed: 12/24/2022] Open
Abstract
Purpose To evaluate the level of human papilloma virus (HPV)-related knowledge and vaccination willingness of people in Fujian Province, and to explore the factors influencing doctors’ recommendation of HPV vaccine. Methods We conducted two cross-sectional surveys in Fujian Province. The study cohort included 248 medical staff and medical students and 1001 community members. Descriptive statistics were used to identify the general demographics of the participants, along with their knowledge and attitudes regarding HPV and vaccination. Analyses were conducted to identify factors associated with willingness to vaccinate and willingness to recommend vaccination. Results The level of HPV knowledge in Fujian province was found to be low, but more than 80% of participants would like to accept HPV vaccine. Medical staff had a higher willingness to recommend HPV vaccine than students (OR= 4.696, CI: 2.698-8.175), which may be related to work experience and acceptance of vaccine price but not to knowledge level. Conclusion Knowledge of HPV in our community population appears to be lower than that in other regions in China. We suggest that a lack of knowledge may not be the main factor affecting the willingness to vaccinate, but we still needed to raise the level of knowledge about HPV to prevent misunderstandings. When the level of knowledge is high, education and per capita household income are not important factors influencing the willingness to vaccinate; only acceptance of vaccine prices significantly affects the willingness to vaccinate. Inclusion of the HPV vaccine in the national immunization program could help to alleviate public concerns regarding the vaccine to change present situation.

Effectiveness of a Health Talk Education Program on Human Papillomavirus (HPV) Knowledge, Attitudes, and Intentions to Vaccinate Children Among Mothers of Secondary School Boys in Thua Thien Hue Province, Vietnam. Risk Manag Healthc Policy 2020; 13:1207-1214. [PMID: 32884381 PMCID: PMC7443439 DOI: 10.2147/rmhp.s259097] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Accepted: 07/14/2020] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND The incidence of cancer related to human papillomavirus (HPV) that affects males is rising throughout the world. Currently, Vietnamese boys are typically not vaccinated against HPV while girls are. There are only a few studies pertaining to HPV vaccination among boys in Asian countries where parents play the most important role in deciding on such vaccination. We present here the first study to assess the effectiveness of a health talk education program on HPV knowledge, attitudes and intention to vaccinate children among mothers of secondary school students in the Thua Thien Hue province, Vietnam. METHODS This was a quasi-experimental study. Two secondary schools in the Thua Thien Hue province, Vietnam were selected by purposive sampling. A total of 288 mothers of male students of two secondary schools were selected to participate, n=144 as controls and n=144 for the intervention arm for every school. Mothers of male students were invited to answer interview questions. The questionnaires covered social demographics, health history, HPV knowledge and HPV vaccination perception and intention. The study ran from September 2019 to January 2020. RESULTS In total, 279 mothers finished the questionnaires. At the baseline, HPV knowledge in both groups was at the same level (p>0.05). One month after receiving the HPV health talk education, mothers of male students had much higher HPV knowledge than those who did not receive such HPV health talk education. The intervention group also had a much higher HPV vaccination intention than the control group (p<0.05). CONCLUSION Health education was shown in this study to be an effective method to increase HPV knowledge and vaccination intention among mothers of boys in Vietnam.

Abstract
Background: Some Ebola vaccines have been developed and tested in phase III clinical trials. However, assessment of whether public have willingness to purchase or not, especially in unaffected areas, is lacking. The aim of this study was to determine willingness to pay (WTP) for a hypothetical Ebola vaccine in Indonesia. Methods: A cross-sectional study was conducted from 1 August to 30 December 2015 in five cities in Aceh province of Indonesia. Patients’ family members who visited outpatient departments were approached and interviewed about their sociodemographic characteristics, knowledge of Ebola, attitude towards vaccination practice and their WTP for a hypothetical Ebola vaccine. A multivariable linear regression model assessed the relationship between these explanatory variables and WTP. Results: During the study, 500 participants were approached and interviewed. There were 424 (84.8%) respondents who completed the interview and 74% (311/424) expressed their acceptance for an Ebola vaccine. There were 288 participants who were willing to pay for an Ebola vaccine (92.6% out of 311). The mean of WTP was US$2.08 (95% CI: 1.75-2.42). The final multivariable model indicated that young age, high educational attainment, working as a private employee, entrepreneur or civil servant (compared to farmers), being unmarried, and residing in a suburb (compared to a city) were associated with higher WTP. Conclusions: Although the proportion of the participants who would accept the Ebola vaccine was relatively high, the amount they were willing to pay for Ebola vaccine was very low. This finding would indicate the need of subsidies for Ebola vaccine in the country.
