Acceptance and willingness to pay for DTaP-HBV-IPV-Hib hexavalent vaccine among parents: A cross-sectional survey in China. Hum Vaccin Immunother 2024; 20:2333098. [PMID: 38619056 PMCID: PMC11020590 DOI: 10.1080/21645515.2024.2333098] [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: 11/08/2023] [Accepted: 03/16/2024] [Indexed: 04/16/2024] Open
Abstract
DTaP-HBV-IPV-Hib hexavalent vaccine has been used in high-income countries for many years to prevent diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis, and invasive Haemophilus influenzae type b disease. Currently, no hexavalent vaccines have been approved for use in China. Evidence of parental acceptance and interest in hexavalent vaccines can help policy makers and manufacturers make decisions about entering the vaccine market and the immunization program in China. We measured parental acceptance and willingness-to-pay (WTP) for a hexavalent vaccine to provide such evidence. We conducted a cross-sectional survey of children's caregivers in 16 vaccination clinics in seven cities in China and obtained information on socio-demographics, knowledge of disease, confidence in vaccines, previous vaccination experience, and acceptance of and WTP for hexavalent vaccine. Multivariate logistic regression was used to determine factors influencing acceptance, and multivariate tobit regression was used to identify factors impacting WTP. Between April 28 and June 30, 2023, a total of 581 parents of children aged 0-6 years participated in the survey; 435 (74.87%, 95% CI:71.3%-78.4%) parents indicated acceptance of hexavalent vaccine. Residence location, parents' education level, experience paying for vaccination, and disease knowledge scores were key factors affecting parents' choices for vaccination. Mean (SD) and median (IQR) willingness to pay for full 4-dose course vaccination were 2266.66 (1177.1) CNY and 2400 (1600-2800) CNY. Children's age (p < .001), parents' education level (p = .024), and perceived price barriers (p < .001) were significantly associated with WTP. Parents have high acceptance and willingness to pay for hexavalent vaccine. The less money parents have to pay out of pocket, the more willing they can be to accept the vaccine. Therefore, acceptance may increase even further if the vaccine is covered by medical insurance, provided free of charge by the government, or if its price is reduced. Our results provide reference for optimizing and adjusting immunization strategies in China.

Han Y, Wang X, Li X, Zhong Z. The willingness of healthcare workers to be vaccinated against monkeypox and their knowledge about monkeypox: A systematic review and meta-analysis. Heliyon 2024; 10:e35196. [PMID: 39170212 PMCID: PMC11336476 DOI: 10.1016/j.heliyon.2024.e35196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 06/25/2024] [Accepted: 07/24/2024] [Indexed: 08/23/2024] Open
Abstract
Background Vaccination is an important method to address the monkeypox epidemic. We aimed to analyze the knowledge of healthcare workers (HCWs) about human monkeypox and their attitudes toward vaccination.MethodsWe searched PubMed, Embase and Web of Science for articles and performed a meta-analysis using Stata 14.0 with a random-effects model. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results A total of 34 studies with 43,226 HCWs were included in this meta-analysis. The results showed that 54 % (95 % CI: 0.39-0.69) of the HCWs were willing to be vaccinated against monkeypox, and only 40 % (95 % CI: 0.29-0.50) of the HCWs had good knowledge of monkeypox. By analyzing the vaccination history of HCWs, we found that history of smallpox vaccination did not significantly affect the willingness of HCWs to receive another vaccination (OR = 0.53, 95 % CI: 0.23-1.26), whereas HCWs who had been vaccinated with the influenza vaccine (OR = 2.80, 95 % CI: 1.29-6.11) or COVID-19 vaccine (OR = 3.10, 95 % CI: 2.00-4.81) showed greater willingness to receive the monkeypox vaccine. In terms of income, low-income HCWs were less willing to be vaccinated against monkeypox (OR = 0.69, 95 % CI: 0.54-0.89), whereas middle-income HCWs were more willing (OR = 1.45, 95 % CI: 1.04-2.02). Notably, although HCWs with education related to monkeypox had better knowledge of monkeypox than HCWs without education related to monkeypox, the difference was not statistically significant (OR = 1.83, 95 % CI: 0.80-4.18). Conclusions Publicity and education on monkeypox should be strengthened so that more people, especially HCWs, can have a good understanding of monkeypox and be willing to be vaccinated.

A systematic review on knowledge, attitudes, and practices and their determinants. J Infect Public Health 2024; 17:868-880. [PMID: 38555655 DOI: 10.1016/j.jiph.2024.03.012] [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: 10/26/2023] [Revised: 03/01/2024] [Accepted: 03/11/2024] [Indexed: 04/02/2024] Open
Abstract
BACKGROUND West Nile virus (WNV) is a mosquito-borne flavivirus. In humans, 80% of infections are asymptomatic, while approximately 20% experience influenza-like symptoms. Fewer than 1% develop the neuroinvasive form which can lead to encephalitis, meningitis, acute flaccid paralysis, and even death. The global spread of the virus to areas where it was not previously present has become a growing concern. Since the 2000 s, there have been numerous outbreaks affecting local and travelling populations worldwide. Given the lack of a vaccine, preventative measures are primarily focused on surveillance, vector control, and the use of personal protective behaviours (PPBs). The importance of PPBs is central to public health recommendations. However, translating these messages into coherent action by the public can prove challenging, as the uptake of such measures is inevitably influenced by socio-economic factors, awareness, knowledge, and risk perception. METHODS A PRISMA-based systematic research was conducted on EMBASE, PubMed/MEDLINE, and Web of Science databases. PROSPERO registration number CRD42023459714. Quality of studies included in the final stage was evaluated using the Critical Appraisal Checklist for Cross-Sectional Study (CEBMa). RESULTS 2963 articles were screened, and 17 studies were included in the final round. Out of these, six were deemed of high quality, ten were of medium quality, and one was of low quality. In almost all studies considered, both awareness and knowledge of WNV transmission were above 90%, while concern about WNV ranged from 50% to 80%. Concern about the safety of repellents, either with or without DEET, ranged from 27% to 70%. The percentage of people actually using repellents ranged from 30% to 75%, with the lowest usage reported among individuals over 60 years old (29%) and pregnant women (33%), and the highest among students aged 9-11 (75%). Concern for West Nile Virus (WNV) was consistently linked to an increase in taking preventative measures, including the use of repellents, by two to four times across studies. The school-based intervention was effective in increasing the practice of removing standing water (AOR=4.6; 2.7-8.0) and wearing long clothing (AOR=2.4; 95%CI: 1.3-4.3), but did not have a significant impact on the use of repellents. CONCLUSIONS The present systematic review provides an overview of the knowledge, attitudes, and practices (KAP) of WNV and their determinants. While concern about West Nile Virus (WNV) and its effects can be a significant motivator, it is important to promote evidence-based personal protective behaviours (PPBs) to counter unwarranted fears. For example, the use of repellents among the most vulnerable age groups. Given the geographical expansion of WNV, it is necessary to target the entire population preventively, including those who are difficult to reach and areas not yet endemic. The findings of this investigation could have significant implications for public health and support well-informed and effective communication strategies and interventions.

Abstract
The aim of the study is to determine the level of price that individuals living in Türkiye are willing to pay (WTP) for a hypothetical COVID-19 vaccine. In addition, the study also aims to identify the socioeconomic factors affecting that level of WTP. The data is collected via a virtually applied questionnaire. Probit estimations are employed to determine the level of price that is willing to be paid. Further, the socioeconomic factors affecting the revealed WTP level are identified with an ordered-probit estimation strategy. The average price level that the participants are willing to pay for two doses of a hypothetical COVID-19 vaccine which immunes for 12 months is ₺316.93 ($42.66). Higher education groups, public employees, married people, and urban individuals are more likely to pay at higher price levels of hypothetical COVID-19 vaccine. Interestingly, the individuals living with a pregnant woman or a baby, the ones who experienced severe COVID-19 disease and the ones who already decided to be vaccinated are more likely to pay at relatively low-price levels. This study may contribute to broader literature as it will provide evidence from Türkiye for international comparisons.

Abstract
Dengue represents a major public health concern. With effective vaccines in development, it is important to identify motivational factors to maximize dengue vaccine uptake. A cross-sectional, quantitative, electronic survey was administered to a nationally representative adult population (n = 3800) in Argentina, Brazil, Colombia, Mexico, Indonesia, Malaysia, and Singapore. Willingness to vaccinate against dengue, and Knowledge, Attitudes, and Practices (KAP) toward dengue, vector control, prevention, and vaccination were determined. The Capability, Opportunity, Motivation for Behavior change (COM-B) framework was used to identify factors correlated with dengue vaccine(s) uptake. KAP scores (standardized, 0–100% scale) resulted in a low global score for Knowledge (48%) and Practice (44%), and a moderate score for Attitude (66%); scores were comparable across countries. Of all respondents, 53% had a high willingness (Score: 8–10/10) to vaccinate against dengue, which was higher (59%) in Latin America (Argentina, Brazil, Colombia, Mexico) than in Asia Pacific (40%) (Indonesia, Malaysia, Singapore). Key factors significantly (p < 0.05) associated with increased willingness to vaccinate included accessibility to the public (subsidies and incentives) and trust in the healthcare system and government. A common approach to dengue prevention across endemic countries––with some country-specific customization, including education, vaccination, and vector control (multi-pronged)––may reduce dengue burden and improve outcomes.

Abstract
Background Vaccines are a powerful choice to stop disease outbreaks, including covid-19. However, people are hesitant to take vaccinations due to uncertainty about side effects. So, this study aimed to assess covid-19 vaccine side-effect and its associated factors among healthcare workers in Dessie comprehensive specialized hospital, in Ethiopia. Methods An institution-based cross-sectional study was conducted at Dessie Comprehensive and Specialized Hospital among 351 vaccinated healthcare workers from April 25 to May 25, 2021. Self-administrated questionnaires were used by consented health workers. Variance inflation factor (VIF) was used to assess the multicollinearity of independent variables. Bivariable and multivariable binary logistic regression were used to identify significant factors of vaccine side effects. The adjusted odds ratio (AOR) with a 95% confidence interval (CI) was reported as the effect size. Statistical significance was considered at p-value <0.05. Results Overall, of vaccinated healthcare workers, 56.98% (95% CI, 50.86-61.26%) experienced at least one side effect. The majority of the side effects were fever (44.44%), headache (39.03%), fatigue (27.35%), injection site pain (25.93%), and nausea (24.22%). Healthcare workers with (≥10 years) of work experience (AOR: 3.74, 95% CI, 1.32-10.59), Hesitancy to take the first dose of the Covid-19 vaccine (AOR: 3.01, 95% CI, 1.82-4.99), underlying chronic disease (AOR: 14.41, 95% CI, (5.07-40.92)), being on antihypertensive medication (AOR: 0.15; 95% CI (0.02-0.93)), and unsafe perception of vaccine safety (AOR:3.50; 95% CI, 1.43-8.57) were independent factors of Covax vaccine side effect development. Conclusion Overall, common vaccine side effects were identified in healthcare workers who have taken the Covax vaccine. Healthcare workers with (≥10 years) of work experience, Hesitancy to take the first dose, unsafe perception of vaccine safety, and underlined chronic disease were predictors of vaccine side effect occurrence. So, providing vaccine-related information to the community to be vaccinated is mandatory to reduce hesitancy and flaws regarding vaccine safety.

Willingness to Pay (WTP) for COVID-19 Vaccine Booster Dose and Its Determinants in Indonesia. Infect Dis Rep 2022; 14:1017-1032. [PMID: 36547247 PMCID: PMC9778827 DOI: 10.3390/idr14060101] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/03/2022] [Accepted: 12/07/2022] [Indexed: 12/14/2022] Open
Abstract
Willingness to pay (WTP) for booster doses of coronavirus disease 2019 (COVID-19) vaccines is an under studied research topic. Therefore, the current study aimed to investigate the WTP for the booster doses of COVID-19 vaccines and its predictors in Indonesia using an online survey distributed all over the provinces of this low-middle-income country. The WTP was evaluated using a basic dichotomous contingent valuation approach, and its associated determinants were evaluated using a linear regression model. Out of 2935 responders, 66.2% (1942/2935) were willing to pay for a booster dose of the COVID-19 vaccine. The majority of respondents (63.5%) were willing to pay within a price range of 100,000-500,000 Indonesian rupiah (IDR), i.e., USD 6.71-33.57. Being older than 40 years, having a higher educational level, having a higher income, knowing and understanding that booster doses were important, and having a vaccine status that is certified halal (permissible in Islamic law), were all associated with a higher WTP for the booster dose of COVID-19 vaccines. The study findings imply that the WTP for a booster dose of COVID-19 vaccination in Indonesia is lower compared to acceptance of vaccines provided free of charge. This WTP data can be utilized to develop a pricing scheme for the booster doses of COVID-19 vaccination in the country with potential benefits in other low-income countries. The government may be required to provide subsidies for the herd immunity vaccination process to proceed as anticipated. Furthermore, the public community must be educated on the importance of vaccination as well as the fact that the COVID-19 epidemic is far from being over.

Abstract
PURPOSE This research aimed to explore individuals' willingness to pay (WTP) and studied the role of family decision makers in WTP for COVID-19 vaccines. METHODS A self-administered online questionnaire evaluating the willingness of community residents to pay for booster vaccination of COVID-19 vaccine was conducted among families in a community in Taizhou, China. The logistic regression model was performed to identify the factors associated with WTP for the COVID-19 vaccines, and all data were analysed by R software, version 4.1.0. RESULTS 44.2% and 43.7% of 824 community residents were willing to pay for the first two doses and the booster dose of the COVID-19 vaccine, respectively. Decision-makers were more willing to pay for both the first two doses and the boost dose of the COVID-19 vaccines, with OR (95%CI) being 1.75 (1.25-2.47) and 1.89 (1.34-2.67), respectively. Besides, participants' WTP for COVID-19 vaccines were also associated with their occupation and monthly household income. CONCLUSION This study found that family decision-makers were more willing to pay for both the first two doses and the booster dose of COVID-19 vaccines in Taizhou, China. To improve the WTP for COVID-19 vaccines, public policy programs need to conduct a comprehensive cost-benefit analysis and focus on the role of family decision makers in vaccination.Key MessagesA study evaluating the willingness of community residents to pay for booster vaccination of COVID-19 vaccine was conducted among families in a community in Taizhou, China.Family decision-makers were more willing to pay for both the first two doses and the booster dose of COVID-19 vaccines.To improve the WTP for COVID-19 vaccines, public policy programs need to conduct a comprehensive cost-benefit analysis and focus on the role of family decision-makers in vaccination.

Aram SA, Hagan JE, Mansoh GKA, Saalidong BM, Lartey PO, Ahinkorah BO, Seidu A, Ameyaw EK, Appiah A, Hotor DW, Gyimah J. Association between health and safety perceptions of COVID-19 vaccine and its uptake in Ghana. PUBLIC HEALTH CHALLENGES 2022; 1:e20. [PMID: 37519313 PMCID: PMC9874404 DOI: 10.1002/puh2.20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 08/09/2022] [Indexed: 08/01/2023]
Abstract
Background Attitudes towards vaccines have affected COVID-19 vaccination programs in many countries. This study sought to evaluate the effects of general perceptions on the safety and health concerns and the confidence in COVID-19 vaccines on its uptake in Ghana. Methods A cross-sectional online survey was conducted between January and March 2021. The outcome variables for this study were "Taking mandatory COVID-19 vaccine" and "Taking voluntary COVID-19 vaccine". The data were subjected to both descriptive (frequency, percentages, and chi-square tests) and inferential (complementary log-log logistic regression) analyses. Results Out of 620 Ghanians who participated in the survey, about 80% of the participants believed that vaccines were good for one's health and 73% had confidence on COVID-19 vaccine safety; although 81% of the respondents were particularly concerned about the source of the vaccine. 79% and 71% of respondents indicated their willingness for mandatory and voluntary COVID-19 vaccination, respectively. In all operationalized regression models, Ghanaians who believed that vaccines are healthy (OR = 1.998, Cl = 1.345-2.968; OR = 1.652, Cl = 1.050-2.601) and those who had confidence in a COVID-19 vaccine safety (OR = 4.405, Cl = 3.136-6.188; OR = 8.340, Cl = 5.471-12.713) were more likely to take a mandatory or voluntary COVID-19 vaccine compared to those who thought and believed otherwise. Individual preferences and/or intentions towards COVID-19 vaccine uptake and uptake route (i.e., mandatory, voluntary) were influenced by multifaceted determinants: biosocial (age, marital status, education), socio-cultural (religion, source of vaccine as a concern), and location (geographical zone) factors. Conclusion To consolidate and possibly increase vaccine uptake in response to the COVID-19 pandemic in Ghana, health education and promotion programs should aim at creating awareness on the benefits of vaccine uptake while addressing the health and safety concerns on the potential side effects through evidence-based community messaging from credible sources. It is important to show specific commitment to transparency and reliable information to build public trust by decision-makers.

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.

Abstract
OBJECTIVES This study aimed to investigate the willingness to pay (WTP) for a hypothetical vaccine and its associated determinants among the Lebanese general population during one of the peak episodes during the coronavirus disease 2019 (COVID-19) pandemic in Lebanon. METHODS An online survey was developed and delivered to the Lebanese general population. The questionnaire included the participants' sociodemographic characteristics, financial situation, attitude toward vaccination, and WTP for the hypothetical vaccine. The study was based on the contingent valuation method. RESULTS Among 500 individuals solicited, 352 individuals agreed to participate (participation rate = 70.4%); among them, 66% were between 18 and 45 years old, and 54% were women. Notably, 78.1% of the respondents were ready to pay for this hypothetical vaccine even if the vaccine will not be covered. The maximum WTP of the Lebanese population was approximately $60 ± $66 (range $3-$500) after excluding extreme values in the sensitivity analysis and ranged between $3 and $500. WTP was associated with the severity of COVID-19 (P<.001), the education level (P=.001), and the place to live during the lockdown (P=.045). There was an association between family income and WTP (P=.004) with a weak correlation. CONCLUSIONS The WTP was comparable with other studies and highly associated with the level of education, the household income, living in the city during the lockdown, and the perceived severity of COVID-19. These findings can help in understanding COVID-19 vaccination acceptance and WTP in Lebanon.

Health-care Workers’ Willingness to Pay for COVID-19 Vaccines in Eastern Ethiopia: Using Contingent Valuation Method. CLINICOECONOMICS AND OUTCOMES RESEARCH 2022; 14:395-404. [PMID: 35615661 PMCID: PMC9126155 DOI: 10.2147/ceor.s361199] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 05/09/2022] [Indexed: 12/01/2022] Open
Abstract
Background Health-care workers (HCWs) are among the highest risk groups for COVID-19 infection. The vaccine is found to be vital for HCWs, their household contacts, and their patients to protect against COVID-19 infection and maintain the safety of health systems. The actual willingness to pay for COVID-19 vaccination and associated factors remain uncertain among health-care workers in Ethiopia. Therefore, studying health-care workers’ willingness to pay (WTP) for COVID-19 vaccination helps to have an insight on valuation of the vaccine. Methods Institution-based cross-sectional study was conducted among 403 randomly selected health-care workers working in health facilities in eastern Ethiopia from February 3 to March 20, 2021. Pretested structured questionnaire was used to collect data. Binary logistic regression analysis was fitted to test the associations between outcome and explanatory variables. A p-value of <0.05 with 95% confidence interval was used to declare statistical significance. Results The magnitude of willingness to pay for a COVID-19 vaccine was 42.8%. The median amounts of money respondents willing to pay was 400 ETB (US$ 10.04). Sex (male, AOR = 2.33; 95% CI: 1.39, 3.93), monthly income (>7000 ETB, AOR = 1.22; 95% CI: 1.11, 2.51), affordability (AOR = 1.99; 95% CI: 1.18, 3.35), fear of side effects (AOR = 3.75; 95% CI: 2.13, 6.60), support vaccinations (AOR = 2.97; 95% CI: 1.65, 5.35), the likelihood of getting COVID-19 infection (AOR = 2.11; 95% CI: 1.26, 3.52) were independent determinants of WTP for a COVID-19 vaccine. Conclusion Health-care workers’ willingness to pay for COVID-19 vaccination was found to be low. Detailed health education and training about COVID-19 vaccines are required regarding their side effects, and efficacy to make an informed decision to enhance the willingness to pay for the vaccine. Moreover, the government should consider providing COVID vaccines free of charge for low-income groups and at an affordable price for those who could pay.

Abstract
In response to an emerging pandemic, there is urgent need for information regarding individual evaluation of risk and preferences toward mitigation strategies such as vaccinations. However, with social distancing policies and financial stress during an outbreak, traditional robust survey methodologies of face-to-face, probabilistic sampling, may not be feasible to deploy quickly, especially in developing countries. We recommend a protocol that calls for a sensitive survey design, acceptance of a web-based approach and adjustments for uncertainty of respondents, to deliver urgently needed information to policymakers as the public health crisis unfolds, rather than in its aftermath. This information is critical to tailor comprehensive vaccination campaigns that reach critical immunity thresholds. We apply our recommendations in a regional study of 16 Latin American countries in the month following index cases of COVID-19. We use a split-sample, contingent valuation approach to evaluate the effects of cost, duration of immunity and effectiveness of the vaccine. Our results show that cost and duration of immunity are significant factors in the decision to vaccinate, while the degree of effectiveness is insignificant, unless the vaccine is 100% effective. Income as well as perceived risk and severity of the virus are important determinants also.

Abstract
Objectives: China was believed to be the country with the world’s highest acceptance rate of the COVID-19 vaccine following several investigations. This study aims to explore the Chinese acceptance of a COVID-19 vaccine before it is made available, including its determinants. Methods: A cross-national online survey was conducted covering all 31 provinces of mainland China. The survey consists of the demographic variables, acceptance of a self-paid COVID-19 vaccine as the dependent variable, and the 3Cs factors (i.e., confidence, convenience, and complacency) as the independent variables. Results: Among the 1,532 participants, 57.9% accepted to get a self-paid COVID-19 vaccine. COVID-19 vaccine acceptors were more likely to be concerned about the effectiveness of the vaccines, believe that they were at risk of COVID-19 infection, have a high perceived susceptibility of COVID-19, and trust in the health care system. Conclusion: Findings indicate that the critical task in the early stage of the COVID-19 vaccine development in China is to increase the tolerance to some intuitive concerns about the vaccines, put more emphasis on the communication of the saliency of the disease threats, and effectively translate people’s trust in the government into vaccine acceptance.

Abstract
Background: It is critical to understand the factors that could affect the acceptance of the coronavirus disease 2019 (COVID-19) vaccine in the community. The aim of this study was to determine factors that could possibly affect the acceptance of Indonesian citizens of COVID-19 vaccination using a Technology Acceptance Model (TAM), a model how users come to accept and use a technology. Methods: An online survey was conducted between the first and fifth of November, 2020. Participants were asked to respond to questions on acceptance, perceived usefulness, perceived ease of use, perceived religiosity towards, and amount of information about COVID-19. This study used the Technology Acceptance Model (TAM) as the framework to decide factors that affect vaccine acceptance. Structural Equation Model was employed to assess the correlation between all explanatory variables and vaccine acceptance. Mann-Whitney test and Kruskal-Wallis rank were employed to assess demographic factors associated with acceptance. Results: In total, 311 responses were included for analysis. Our TAM model suggested that high perceived usefulness significantly increased COVID-19 vaccine acceptance and high perceived ease of use significantly increased the perceived usefulness. Perceived religiosity did not substantially affect vaccine acceptance. The amount of information on COVID-19 also did not significantly affect vaccine acceptance. Our data suggested that vaccine acceptance was associated with age, type of occupation, marital status and monthly income to some degree. Conclusion: Since perceived usefulness affects vaccine acceptance, the government should focus on the usefulness of the vaccine when promoting the COVID-19 vaccine to Indonesian citizens. In addition, since perceived ease of use significantly affects users' acceptance to COVID-19 vaccine, the easier to acquire the vaccine in the community, the higher chance that the citizens are willing to be vaccinated.

Abstract
Several COVID-19 vaccines have been on the market since early 2021 and may vary in their effectiveness and safety. This study characterizes hesitancy about accepting COVID-19 vaccines among parents in Shanghai, China, and identifies how sensitive they are to changes in vaccine safety and effectiveness profiles. Schools in each township of Minhang District, Shanghai, were sampled, and parents in the WeChat group of each school were asked to participate in this cross-sectional Internet-based survey. Parents responded to questions about hesitancy and were given information about five different COVID-19 vaccine candidates, the effectiveness of which varied between 50 and 95% and which had a risk of fever as a side effect between 5 and 20%. Overall, 3673 parents responded to the survey. Almost 90% would accept a vaccine for themselves (89.7%), for their child (87.5%) or for an elderly parent (88.5%) with the most ideal attributes (95% effectiveness with 5% risk of fever). But with the least ideal attributes (50% effectiveness and a 20% risk of fever) these numbers dropped to 33.5%, 31.3%, and 31.8%, respectively. Vaccine hesitancy, age at first child’s birth, and relative income were all significantly related to sensitivity to vaccine safety and effectiveness. Parents showed a substantial shift in attitudes towards a vaccine based on its safety and effectiveness profile. These findings indicate that COVID-19 vaccine acceptance may be heavily influenced by how effective the vaccine actually is and could be impeded or enhanced based on vaccines already on the market.

Abstract
Differences in obtaining a vaccine vary based on a multitude of factors including perceptions of vaccine safety, efficacy and willingness to pay (WTP). This study focuses on parent perceptions toward a vaccine for COVID-19 including their WTP decisions for their children and themselves. A mixed methods design using a cross-sectional survey was used to assess the perceptions of US parents, with children under 18, in response to the COVID-19 pandemic. The survey was administered online in November 2020 and 584 final responses were collected. The questionnaire consisted of approximately 37 closed and open-ended questions regarding personal background information; awareness, knowledge, and experience of the virus; perception toward vaccines and COVID-19; and the contingent valuation of a hypothetical COVID-19 vaccine. WTP was found to be higher for children and a direct relationship between the number of children and WTP was observed. Parents were willing to pay US$228-$291 for a vaccine for themselves and US$243-US$321 for their children. A positive impact on WTP was found with self-reported parent health status but not children. The findings of this study have important implications for policy programs which require detailed cost-benefit analyses. WTP for a COVID-19 vaccine is crucial to determine the partial benefits of vaccinating to reduce the risk of repetitive widespread outbreaks.

Abstract
The COVID-19 pandemic has caused negative impacts both on populations' health worldwide. COVID-19 vaccines are currently developed and tested in clinical trials. However, limited studies have investigated the willingness to get COVID-19 vaccines in populations. Therefore, the study aimed to determine the individual's willingness to accept and pay for COVID-19 vaccines, and knowledge, attitude, and perceptions (KAP) of COVID-19 vaccines, which hopefully will be available soon. Non-pregnant Chinese adults aged ≥18 years were asked to complete a self-administered KAP COVID-19 vaccine questionnaire distributed between March and May 2020. A total of 1179 participants (574 males and 605 females) were included and the mean age was 36.0 ± 11.5 years. Both the willingness to be vaccinated against COVID-19 and pay for COVID-19 vaccines were high (77.4% and 81.1%), respectively. Also, the most acceptable price range of COVID-19 vaccine was ¥501-1000 (US $ 75-149). Education and willingness to be vaccinated were significantly associated with some of the responses in KAP (P < .05). In conclusion, our study reported high willingness to be vaccinated against COVID-19 and pay for COVID-19 vaccines in Chinese population. Our findings also provided some important contributions for public health policy makers to formulate appropriate vaccination programs.

Abstract
As studies indicate that people perceive COVID-19 as a threatening disease, the demand for a vaccine against the disease could be expected to be high. Vaccine safety concerns might nevertheless outweigh the perceived disease risks when an individual decides whether or not to accept the vaccine. We investigated the role of perceived risk of COVID-19 (i.e., perceived likelihood of infection, perceived disease severity, and disease-related worry) and perceived safety of a prospective vaccine against COVID-19 in predicting intentions to accept a COVID-19 vaccine. Three Finnish samples were surveyed: 825 parents of small children, 205 individuals living in an area with suboptimal vaccination coverage, and 1325 Facebook users nationwide. As points of reference, we compared the perceptions of COVID-19 to those of influenza and measles. COVID-19 was perceived as a threatening disease—more so than influenza and measles. The strongest predictor of COVID-19 vaccination intentions was trusting the safety of the potential vaccine. Those perceiving COVID-19 as a severe disease were also slightly more intent on taking a COVID-19 vaccine. Informing the public about the safety of a forthcoming COVID-19 vaccine should be the focus for health authorities aiming to achieve a high vaccine uptake.

Abstract
Background Although there is no licensed vaccine for monkeypox, smallpox vaccine has been shown to be 85% effective in preventing the monkeypox. This study was conducted to assess the willingness of frontline healthcare providers to be vaccinated with smallpox vaccine to prevent monkeypox. Methods A cross-sectional study was conducted in Indonesia. The willingness was assessed under two scenarios: fully subsidized and non-subsidized vaccine. Explanatory variables such as sociodemographic profile, workplace and professional characteristics, and knowledge of monkeypox were collected. A logistic regression assessed the influence of these explanatory variables on participants’ willingness. Results Out of 510 received participants’ responses, 407 (79.8%) were analyzed. With a fully subsidized vaccine scenario, 381 (93.6%) of the participants were willing to be vaccinated and in an unadjusted analysis, gender, education, monthly income, and type of workplace were associated with willingness. With a non-subsidized vaccine (i.e. the vaccine price was US$ 17.9), the proportion who were willing to be vaccinated decreased to 71.9%. In adjusted analyses for both scenarios, gender was the only independent predictor for willingness; men were less willing to be vaccinated than women, adjusted odds ratio (aOR): 0.37; 95% confidence interval (CI): 0.16, 0.87 and aOR: 0.42; 95%CI: 0.27, 0.67, respectively for subsidized and non-subsidized scenario. Conclusion Vaccine price and gender are important factors for physicians' willingness to be vaccinated for smallpox vaccine prevent monkeypox in Indonesia. These findings indicate that achieving high vaccine converge may require partially or fully subsidized vaccines, along with a clear guideline and recommendation from authorities.

Abstract
BACKGROUND A clinical trial is ongoing to evaluate the safety and efficacy of a monkeypox vaccine among healthcare workers (HCWs). 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.

Abstract
Zika virus (ZIKV) can cause pregnancy loss and congenital Zika syndrome, among other poor health outcomes. The ZIKV epidemic in 2015-2017 disproportionately affected pregnant women in poor-resource settings. We aimed to understand perceptions and attitudes towards a hypothetical ZIKV vaccine, women's willingness to be vaccinated, and potential barriers and facilitators for vaccine acceptance in 1) migrant women living in Spain who travelled to their countries of origin and were diagnosed with ZIKV infection during pregnancy, and their healthcare providers, and 2) women living in Colombia who delivered a child with microcephaly. An exploratory qualitative study based on phenomenology and grounded theory was conducted. Data were collected through in-depth, paired and semi-structured interviews. Overall, women from both sites were willing to receive a hypothetical ZIKV vaccine. However, some expressed concerns of being vaccinated during pregnancy, yet they would accept it if the vaccine was recommended by a healthcare professional they trust. Main fears towards vaccination were related to vaccine safety and potential adverse effects on child's health. Women reported feeling hesitant to participate in a ZIKV vaccine trial. These results may contribute to guiding the effective delivery of future ZIKV vaccines among populations most at risk and particularly vulnerable.

Abstract
How countries, particularly low- and middle-income economies, should pay the coronavirus disease 2019 (COVID-19) vaccine is an important and understudied issue. We undertook an online survey to measure the willingness-to-pay (WTP) for a COVID-19 vaccine and its determinants in Indonesia. The WTP was assessed using a simple dichotomous contingent valuation approach and a linear regression model was used to assess its associated determinants. There were 1,359 respondents who completed the survey. In total, 78.3% (1,065) were willing to pay for the COVID-19 vaccine with a mean and median WTP of US$ 57.20 (95%CI: US$ 54.56, US$ 59.85) and US$ 30.94 (95%CI: US$ 30.94, US$ 30.94), respectively. Being a health-care worker, having a high income, and having high perceived risk were associated with higher WTP. These findings suggest that the WTP for a COVID-19 vaccine is relatively high in Indonesia. This WTP information can be used to construct a payment model for a COVID-19 vaccine in the country. Nevertheless, to attain higher vaccine coverage, it may be necessary to partially subsidize the vaccine for those who are less wealthy and to design health promotion materials to increase the perceived risk for COVID-19 in the country.

Front Public Health 2020; 8:381. [PMID: 32760691 PMCID: PMC7372105 DOI: 10.3389/fpubh.2020.00381] [Citation(s) in RCA: 344] [Impact Index Per Article: 86.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 06/30/2020] [Indexed: 12/21/2022] Open
Abstract
Introduction: Several vaccine candidates are being clinically tested in response to the 2019 coronavirus disease (COVID-19) pandemic. This study was conducted to assess the acceptance of a 50 or 95% effective COVID-19 vaccine, when it becomes available in southeast Asia, among the general population in Indonesia. Methods: A cross-sectional online survey was conducted between March 25 and April 6, 2020. Participants were asked if they would accept a free vaccine which was 95 or 50% effective. Using a logistic regression model, we assessed the associations between sociodemographic characteristics, exposure to COVID-19 information, or perceived risk of infection with acceptance of a hypothetical COVID-19 vaccine. Results: Among 1,359 respondents, 93.3% of respondents (1,268/1,359) would like to be vaccinated for a 95% effective vaccine, but this acceptance decreased to 67.0% (911/1,359) for a vaccine with 50% effectiveness. For a 95% effective vaccine, being a healthcare worker and having a higher perceived risk of COVID-19 infection were associated with higher acceptance, adjusted odds ratio (aOR): 2.01; 95%CI: 1.01, 4.00 and aOR: 2.21; 95%CI: 1.07, 4.59, respectively; compared to civil servants, being retired was associated with less acceptance (aOR: 0.15; 95%CI: 0.04, 0.63). For a 50% effective vaccine, being a healthcare worker was also associated with greater acceptance, aOR: 1.57; 95%CI: 1.12, 2.20. Conclusion: Acceptance of a COVID-19 vaccine was highly influenced by the baseline effectiveness of the vaccine. Preparing the general population to accept a vaccine with relatively low effectiveness may be difficult.

Abstract
Objective: To investigate the factors predicting knowledge, attitude, and practices (KAP) toward Zika virus infection among women population in Cebu City, Philippines. Study Design: A cross-sectional survey was conducted from March 2018 to May 2018. Ethical practices were followed. A total of 702 women was approached and finally 516 completed the survey. Methods: Descriptive analysis was undertaken for the participants' characteristics. Kolmogorov-Smirnov test was applied to declare the nature of data distribution. To determine the role of socio-demographic characteristics on KAP, differences in socio-demographic status were compared with the KAP scores using the one-way analysis of variance or Kruskal-Wallis test with p < 0.05 as significant. Logistic regression analysis was used to determine the predictors of each KAP domain (good and poor). Results: There was a significant positive correlation between level of education and KAP scores. Also, there was a significant positive correlation between employment and KAP scores. Knowledge score was a significant predictor of practice score (b = 1.261, p = 0.024), and attitude score was also a significant predictor of practice score (b = 0.183, p = 0.039). However, knowledge score was not a significant predictor of attitude score (b = 0.316, p = 0.247). Conclusions: The present findings provided an overall view of KAP on Zika virus infection among females in Philippines and the socio-demographic factors that affected their KAP. Women with postgraduate education and being in higher profession were the predictors influencing the KAP scores of this female population. Women with postgraduate education was the strongest predictor.

Abstract
Introduction Cholera is a highly infectious disease and remains a serious public health burden in Bangladesh. The objective of the study was to measure the private demand for oral cholera vaccines (OCV) in Bangladesh and to investigate the key determinants of this demand, reflected in the household’s willingness to pay (WTP) for oral cholera vaccine. Methods A contingent valuation method was employed in an urban setting of Bangladesh during December 2015 to January 2016. All respondents (N = 1051) received a description of World Health Organization (WHO) prequalified OCV, Shanchol™. Interviews were conducted with either the head of households or their spouse or a major economic contributor of the households. Respondents were asked about how much at maximum they were willing to pay for OCV for their own and their household members’ protection. Results are presented as the average and median of the reported maximum WTP of the respondents with standard deviations and 95% confidence interval. Natural log-linear regression model was employed to examine the factors influencing participants’ WTP for OCV. Results About 99% of the respondents expressed WTP for OCV with a maximum mean and median WTP per vaccination (2 doses) of US$ 2.23 and US$ 1.92 respectively. On the household level with an average number of 4.62 members, the estimated mean WTP was US$ 10 (median: US$ 7.69) which represents the perceived demand for OCV of a household to vaccinate against cholera. Conclusions The demand of vaccination further indicates that there is a potential scope for recovering a certain portion of the expenditure of immunization program by introducing direct user fees for future cholera vaccination in Bangladesh. Findings from this study will be useful for the policy-makers to make decision on cost-recovery in future oral cholera vaccination programs in Bangladesh and in similar countries.

Health professionals' acceptance and willingness to pay for hepatitis B virus vaccination in Gondar City Administration governmental health institutions, Northwest Ethiopia. BMC Health Serv Res 2019; 19:796. [PMID: 31690313 PMCID: PMC6833239 DOI: 10.1186/s12913-019-4671-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Accepted: 10/23/2019] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Hepatitis B virus (HBV) infection is a global public health problem. The burden of the disease is high in low and middle income countries like Ethiopia. However, for highly vulnerable groups such as health professionals, vaccination coverage is a major issue in the developing countries where health professionals are expected to pay for vaccination. Therefore, the objective of this study was to assess health professionals' acceptance and willingness to pay (WTP) and associated factors for vaccination against HBV. METHODS Cross-sectional study was conducted from March to April, 2017 in Gondar city administration governmental health institutions among 423 health professionals. Simple random sampling method was employed to select the study participants. Data were collected using self- administered questionnaire. Tobit model was used to analyze the determinants of WTP and the maximum amount of money the individuals might pay for HBV vaccination. P-value < 0.05 was considered statistically significant. RESULT A total of 423 health professionals (physicians, nurses, midwives, laboratory technicians/technologists, and others) participated in the study with a response rate of 100, and 62.4% of them were willing to pay for HBV vaccination. The mean amount of money the participants might pay for HBV vaccination was 325.83 ± 283.46 ETB (US$ 14.39 ± 12.52). The study indicated that the WTP for HBV vaccination of health professionals from health centers was 179.41 ETB less compared to health professionals from hospital. The WTP for HBV vaccination of the participants who had no experience of seeing previous patients with HBV was 157.87 ETB less compared to participants who had experience of seeing previous patients with HBV. As monthly income of the study participants increased by one ETB, the WTP was increased by 0.027 ETB. CONCLUSION The study revealed that the mean amount of money the participants might pay for HBV vaccination was much less than the market price for HBV vaccination. Type of workplace and experience of seeing/observing patients with HBV, and income were the predictors of WTP for HBV vaccination. Availing the vaccine with affordable cost in governmental health institutions may increase WTP of health professionals for HBV vaccination.

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.

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.

Knowledge and attitude towards pregnancy-related issues of Zika virus infection among general practitioners in Indonesia. BMC Infect Dis 2019; 19:693.

Abstract
Background The aim of this study was to assess the knowledge and attitudes towards pregnancy-related issues of Zika virus (ZIKV) infection among general practitioners (GPs), a frontline healthcare worker group, in Indonesia. Methods A cross-sectional, online survey assessing knowledge and attitudes towards ZIKV infection on multiple-item scales was sent to GPs in the Sumatra and Java islands of Indonesia. The associations between independent factors and either knowledge or attitude were assessed with logistic regressions. The correlation and association between knowledge and attitude were estimated. Results We included 457 (53.7%) out of 850 responses in the analysis. Among these, 304 (66.5%) and 111 (24.2%) respondents had a good knowledge and attitude, respectively. No demographic, workplace, professional development, or experiential characteristics related to ZIKV infection were associated with knowledge. In the multivariate analysis, only contact experience was associated with attitude. There was a significant, positive correlation between knowledge and attitude scores. Conclusions Although knowledge of pregnancy-related complications of ZIKV infection is relatively high among GPs in Indonesia, more than 75% of them had a poor attitude towards pregnancy-related issues of Zika. Strategies for enhancing the capacity of GPs to develop positive attitudes and respond to ZIKV infection are needed.

Willingness to pay for hepatitis B vaccination in Selangor, Malaysia: A cross-sectional household survey. PLoS One 2019; 14:e0215125. [PMID: 30964934 PMCID: PMC6456223 DOI: 10.1371/journal.pone.0215125] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 03/28/2019] [Indexed: 12/17/2022] Open
Abstract
Background In Malaysia, one million individuals are estimated to be infected with the hepatitis B virus. A vaccine for infants has been compulsory since 1989, whereas those born before 1989 need to spend their own money to be vaccinated in private clinics or hospitals. The aim of this study was to investigate and ascertain the determinants of willingness to pay (WTP) for adult hepatitis B vaccine in Selangor, Malaysia. Methods In 2016, 728 households were selected through a stratified, two stage cluster sample and interviewed. Willingness to pay for hepatitis B vaccine was estimated using the Contingent Valuation Method, and factors affecting WTP were modelled with logit regression. Results We found that 273 (37.5%) of the households were willing to pay for hepatitis B vaccination. The mean and median of WTP was estimated at Ringgit Malaysia (RM)303 (approximately US$73) for the three dose series. The estimated WTP was significantly greater in those with higher levels of education, among Malays and Chinese (compared to others, predominantly Indians), and for those with greater perceived susceptibility to hepatitis B virus infection. Other factors–perceived severity, barriers, benefits and cues to action–were not significantly associated with WTP for adult hepatitis B vaccination. Conclusion Additional resources are needed to cover the households that are not willing to pay for hepatitis B vaccination. More awareness (particularly in regards to hepatitis B virus susceptibility) could change the national perception towards self-paid hepatitis B virus vaccination and increase hepatitis B vaccine coverage.
