A COVID-19 vaccine is the key to beating the virus, and effective vaccines are going to be available in the near future. It is urgent to estimate the acceptability of COVID-19 vaccines and their value to individuals, in order to develop an effective public vaccination strategy. Based on a survey of 1,188 randomly selected respondents in China, we analyzed Chinese consumers' willingness to get a COVID-19 vaccine and their willingness to pay for it. We find that 79.41% of the respondents are willi ...[more]

Project description:BackgroundThe coronavirus disease (COVID-19) pandemic has considerably affected the lives of people worldwide, impacting their health and economic welfare, and changing the behavior of our society significantly. This situation may lead to a strong incentive for people to buy a vaccine. Therefore, a relevant study to assess individuals' choices and the value of change in welfare from a COVID-19 vaccine is essential.ObjectiveThis study aimed to estimate the willingness-to-pay (WTP) value for a vaccine for COVID-19. We also identify the variables that influence individual vaccination decisions, which could be used in the design of vaccination promotion strategies.MethodsWe use the contingent valuation method in its double-bounded dichotomous choice format. The estimation coefficients are calculated according to the maximum likelihood method under the assumption of a probit distribution. The sample consisted of 531 individuals, mainly from middle- and high-income socioeconomic groups from Chile between enrolled between 10 July and 10 August 2020.ResultsThe results show a high WTP for the COVID-19 vaccine, with a value up to US$232. Income and education levels and having family members with COVID-19 increased the likelihood of persons paying for a vaccine. There is also a greater fear as the pandemic progresses that people will get sick from COVID-19.ConclusionsThe high WTP value creates an opportunity for formulating public health policy. The results of this study suggest that governments can provide the vaccine free to low-income groups and allow those with higher incomes to acquire the vaccine through the private sector by paying. This will be useful especially for countries with economic difficulties.

Project description:This study investigates how people in Japan perceived the severity of and probability of infection from coronavirus disease 2019 (COVID-19), and how their willingness to purchase a hypothetical vaccine depends on these perceptions and their risk attitudes. We conducted a large-scale panel survey three times between 13 March to 13 April 2020 in Japan. By analyzing the data, we found that the perception of COVID-19 became more serious. The estimation of the fixed effect model reveals that a person becomes more willing to pay for a vaccine as the person evaluates COVID-19 as a more severe disease, considers a higher probability of infection, and becomes more risk averse. Since the sensitivity of willingness to pay for the vaccine on risk aversion increased during the period, the change in risk attitude contributed to an increase in willingness through the sensitivity channel, while it decreased through the magnitude channel.

Project description:BackgroundThe introduction of the COVID-19 vaccine necessitates the assessment of individual perception regarding the vaccine. This study aimed to assess the perception of community members and willingness to pay for the prospective COVID-19 vaccine in Ibadan, Nigeria.MethodsA descriptive cross-sectional study design was used. Data were collected using an interviewer-administered questionnaire in September 2020. We studied community members aged 15 years and above using a multi-stage sampling technique. The perceptions of respondents about the COVID-19 vaccine were assessed on eight questions using the five-point Likert scale with a score point of "1" assigned for "Strongly Agree", "2" for "Agree", "3" for "Not decided", "4" for "Disagree", and "5" for "Strongly disagree". During analysis, we reverse-coded the options by assigning a point of "1" for "Strongly disagree", "2" for "Disagree", "3" for "Not decided", "4" for "Agree", and "5" for "Strongly disagree". However, questions asked in the negative directions were not reverse-coded during analysis. Eight questions were used to assess the perception of community members regarding the prospective COVID-19 vaccine, and overall, the maximum point was 40. Points greater than or equal to 32 points (80%) implied positive perception. Descriptive statistics were done. Chi-square tests were used for the assessment of associations between sociodemographic characteristics and willingness to pay for the prospective COVID-19 vaccine. We conducted logistic regression tests on statistically significant variables at p-values <0.05.ResultsThe mean age of the 440 respondents studied was 37.22 ± 15.36 years, 193 (49.00%) were males, and 292 (67.30%) of the respondents had heard of the prospective COVID-19 vaccine. Among them, 232 (79.50%) respondents had positive perception regarding COVID-19 vaccine. Individuals in the fifth wealth quintile were ten times more likely to be willing to pay for the prospective COVID-19 vaccine compared to those in the first wealth quintile (Adjusted Odds Ratio = 9.57, 95% CI [2.88-31.82], p = <0.01).ConclusionThe prospective COVID-19 vaccine should be subsidized or made freely available to everyone.

Project description:Background and objectiveThe coronavirus disease 2019 (COVID-19) pandemic is a major international threat and vaccination is the most robust strategy to terminate this crisis. It is helpful for policymakers to be aware of community preferences about vaccines. The present study aims to investigate the public's preferences and willingness to pay for the COVID-19 vaccine in Iran.MethodsThis research is a cross-sectional study performed using a discrete choice experiment for a sample of the public population of several provinces of Iran in 2021. The samples were divided into two groups: one group expressed their preferences regarding the vaccine's attributes, and another group expressed their preferences regarding prioritizing individuals to get the vaccine. The discrete choice experiment design included five attributes including effectiveness, risk of severe complications, price, location of vaccine production, and duration of protection related to preferences for vaccine selection and six attributes including age, underlying diseases, employment in the healthcare sector, the rate of virus spread, the necessary job, and cost to the community related to preferences for prioritizing individuals to get the vaccine. A total of 715 individuals completed the questionnaire. The conditional logit regression model was used to analyze the discrete choice experiment data. Willingness to pay for each attribute was also calculated.ResultsThe willingness to pay for the COVID-19 vaccine with 90% (70%) efficacy, the risk of severe complications for 1 (5) person per one million people, imported (domestic) vaccine, and 24-month (12-month) duration of protection attributes was about US$71 (US$37). The preference for vaccination for respondents was enhanced by increasing the efficacy and the duration of vaccine protection and decreasing complications and costs. The likelihood of prioritizing individuals to get a vaccination was increased for a person with an underlying disease, employment in the healthcare sector, the necessary job for the community, the high potential for virus spread in the community, and the high cost of death to the community. The age variable was not statistically significant for prioritizing individuals to get the vaccine.ConclusionsIn the setting of the COVID-19 vaccination program, the public's preferences identified in this study should be considered. The obtained results provide useful information for policymakers to identify individual and social values for an appropriate vaccination strategy.

Project description:IntroductionPrior to the COVID-19 pandemic, it took at least several years to develop vaccines for prevention of infectious diseases. The COVID-19 vaccine is the first to be developed within a period of one year. The expediency associated with the development of the COVID-19 vaccine has however been hampered by vaccine hesitancy and other relevant factors that could influence consequent immunisation. This study aimed at investigating factors associated with vaccine hesitancy and willingness to pay for COVID-19 vaccination.MethodsA cross-sectional approach was used to undertake online and physical data collection with a validated questionnaire.ResultsA total of 1767 valid responses were received, female participants were in the minority (42.2%), majority (54.9%) of the study participants were between the ages of 18 and 30 years, and more than half (53.8%) of the participants were educated up to first degree level. Slightly above half (52.9%) of the study participants indicated that they were worried about side effects that may be associated with COVID-19 vaccines, and this may likely prevent them from taking the vaccine. A strong majority (85.1%) of the study participants indicated that COVID-19 vaccine should be administered at no cost to citizens. Only a quarter (26%) of the participants were willing to pay a fee for COVID-19 vaccination. Also, older participants and those that had been previously infected with COVID-19 were more likely to pay for COVID-19 vaccination.ConclusionThis study provides critical insights which could influence immunisation efforts during the pandemic. An early understanding of population perceptions of the COVID-19 vaccine can be invaluable in designing successful campaigns. This is even more critical, given supply limitations, access issues and vaccines' inequity occasioned by the international scramble.

Project description:This study discusses the identification of factors affecting consumers' willingness to pay a price premium for ecological goods. The study was carried out in selected regions of Ukraine, in the cities of Kharkiv and Kyiv. The study applied various research methods, in particular public opinion analysis based on conducted surveys and the statistical inference method. The conducted research may constitute the scientific basis for the assessment of this market segment development. The comparison of consumer attitudes, presented by the residents of major Ukrainian cities regarding environmental goods, revealed their willingness to pay a price premium depending primarily on the purchasing power of the population, but also on gender, age, and social status. The analysis of differences in the cross-tabulation of quality characteristics was performed using Pearson's chi-square test, which showed that, for example, men were more willing than women to choose environmental products due to their environmental safety and their selection was more often than in case of women based on environmental goods' price. The collected research results can be used to assess the development prospects of environmental goods' market, to construct the set of measures increasing the willingness level of domestic consumers to pay a price premium for ecological products, and to take up decisions about the production of ecological goods.

Project description:BackgroundPayment 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.MethodsThis 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.ResultsA 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).ConclusionChinese 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.

Project description:PurposeTo explore the wider determinant factor of citizens' spirituality, health engagement, health belief model, and attitudes towards vaccines toward acceptance and willingness to pay for a Coronavirus disease 2019 (COVID-19) vaccination.MethodsA community-based cross-sectional online investigation with convenience sampling was utilized to recruit 1423 citizens from 18 districts across Indonesia between December 14, 2020 and January 17, 2021. Descriptive statistics, One-way analysis of variance, Pearson correlation, Independent t-tests, and multiple linear regression were examined.ResultsSpirituality, health engagement and attitude toward vaccines, as well as health beliefs constructs (all scores of perceived benefits and barriers) were significant key factors of acceptance of vaccines. Interestingly, the spirituality, attitude toward vaccine, and health beliefs constructs including perceived susceptibility, and benefits indicated a significantly higher willingness.ConclusionsResults demonstrated the utility of spirituality, health engagement, health belief model, and attitudes towards vaccines in understanding acceptance and willingness to pay for a vaccine. Specifically, a key obstacle to the acceptance of and willingness to pay COVID-19 vaccination included a high score of the perceived barrier construct. Moreover, the acceptance of and willingness to pay could be impaired by worries about the side-effects of a COVID-19 vaccination.

Project description:Vaccines are the most efficient and cost-effective tool to halt the transmission and prevention of COVID-19. The current study examined the willingness of parents to vaccinate their children against COVID-19. This was a cross-sectional study that used a questionnaire based on the Health Belief Model, previous history of COVID-19, willingness to accept, and willingness to pay for the COVID-19 vaccine. The questionnaire was administered among parents of children aged 5 to 11 years. Descriptive statistics, χ2 tests, and regression analysis were carried out for data analysis. A total of 474 respondents participated in this survey with a response rate of 67.7%. In our study, a majority of the respondents exhibited a willingness to accept the COVID-19 vaccine for their children (Definitely yes/Probably yes = 252, 53.2%); nevertheless, 229 (48.3%) respondents were unwilling to pay for it. More than three-quarters of the respondents were worried about the probability of COVID-19 infection in their children (n = 361, 76.2%) and were afraid of COVID-19-associated complications (n = 391, 82.5%). Likewise, most respondents showed their concerns regarding the effectiveness of the vaccine (n = 351, 74.1%), vaccine safety (n = 351, 74.1%), and the halal nature of the vaccine (n = 309, 65.2%). Respondents who were aged 40 to 50 years (odds ratio [OR]: 0.101, 95% CI: 0.38-0.268; P < 0.001), family income > 50,000 PKR (OR: 0.680, 95% CI: 0.321-1.442; P = 0.012), and location (OR: 0.324, 95% CI: 0.167-0.628; P = 0.001) were the factors that were likely to impact vaccine acceptance among parents. Education-based interventions are urgently required to improve COVID-19 vaccination acceptance among parents for their children.

Project description:Developing ways to predict and encourage vaccine booster uptake are necessary for durable immunity responses. In a multi-nation sample, recruited in June-August 2021, we assessed delay discounting (one's tendency to choose smaller immediate rewards over larger future rewards), COVID-19 vaccination status, demographics, and distress level. Participants who reported being vaccinated were invited back one year later (n = 2547) to report their willingness to receive a booster dose, along with reasons for their decision. After controlling for demographic variables and distress level, a greater tendency to discount future rewards was associated with reduced willingness to receive a booster dose. Thematic coding revealed that the most common reason for booster willingness was protection against COVID-19, and for unwillingness was non-necessity. The results identify delay discounting as a behavioral predictor of booster willingness that may be used to inform tailored approaches to increase booster uptake (e.g., trust in science vs. vaccine mandates).
