Vaccines are widely acknowledged as one of the most efficient and effective strategies for preventing diseases. This study, based on two waves of public survey data and complemented by incentivized experiments, investigates how behavioral preferences shape actual decisions to receive COVID-19 vaccinations. By combining these methods, the research aims to enhance both internal and external validity. Our findings indicate that individuals with elevated levels of prosociality show a greater propensity to receive the initial dose of the vaccine, a pattern that holds across both the general public and university students. In contrast, parental decisions regarding child vaccination are significantly associated with greater risk taking and lower omission bias, but not with prosocial preferences.
疫苗被广泛认为是预防疾病最有效率和效果的策略之一。本研究基于两轮公众调查数据，并辅以激励实验，调查行为偏好如何影响接受新冠疫苗接种的实际决策。通过结合这些方法，该研究旨在提高内部效度和外部效度。我们的研究结果表明，亲社会程度较高的个体接种首剂疫苗的倾向更大，这一模式在普通公众和大学生中均成立。相比之下，父母关于儿童疫苗接种的决策与更大的冒险精神和更低的遗漏偏差显著相关，但与亲社会偏好无关。
