    Abstract Background: The 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.
    Objective: This 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.
    Methods: We 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.
    Results: The 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.
    Conclusions: The 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.

    Abstract Background: The prevalence of COVID-19 has a social and economic impact on people, leaving them distressed and fearful of getting infected.
    Objective: To determine the variables attributable to the fear of contracting COVID-19.
    Design: This is a quantitative study based on an online cross-sectional self-administered survey in Chile between 10 July 2020 and 10 August 2020.
    Setting and participants: A sample of 531, comprising over 18-year-old participants from middle- and high-income levels, was selected.
    Outcome measures: Estimations were obtained using a probit regression model with marginal effects.
    Results: Fear prevailed mainly in women. It has a positive relationship with variables such as chronic illnesses, infectious family or relatives, reduction in economic activity and perception of bad government response to a pandemic. Fear has a negative relationship with knowledge about COVID-19, education level and ageing. Moreover, those who consider socioeconomic impact less important than health care do not fear a COVID-19 infection.
    Discussionand conclusion: The socioeconomic and health aspects help predict fears. Thus, the government should prioritize these variables in implementing policies. The government's credibility and communication systems can also reduce fears of contracting COVID-19.
    Patient or public contribution: A pilot focus group of COVID-19-recuperated individuals and some members of our interest groups were consulted in the design stage of the study; this helped in constructing the survey questions. Additionally, three independent individuals volunteered to read and comment on the draft manuscript.

    Abstract The COVID-19 pandemic has not only had a negative impact on people's health and life behavior, but also on economies around the world. At the same time, laboratories and institutions are working hard to obtain a COVID-19 vaccine, which we hope will be available soon. However, there has been no assessment of whether an individual and society value ​​a vaccine monetarily, and what factors determine this value. Therefore, the objective of this research was to estimate the individual's willingness to pay (WTP) for a hypothetical COVID-19 vaccine and, at the same time, find the main factors that determine this valuation. For this, we used the contingent valuation approach, in its single and double-bounded dichotomous choice format, which was based on a hypothetical market for a vaccine. The sample used was obtained through an online survey of n = 566 individuals from Chile. The main results showed that the WTP depends on the preexistence of chronic disease (p≤0.05), knowledge of COVID-19 (p≤0.05), being sick with COVID-19 (p≤0.05), perception of government performance (p≤0.01), employment status (p≤0.01), income (p≤0.01), health care (p≤0.05), adaptation to quarantine with children at home (p≤0.01) and whether the person has recovered from COVID-19 (p≤0.10). According to our discrete choice model in double-bounded dichotomous format, it was concluded that the individuals' WTP is US$184.72 (CI: 165.52-203.92; p < 0.01). This implies a social valuation of approximately US$2232 million, corresponding to 1.09% of the GNP per capita.
