标题： Preferences for COVID-19 vaccine: Evidence from India

摘要： 印度的大规模疫苗接种工作由于疫苗犹豫水平较高而进展缓慢。 这项研究使用了来自1371名受访者在线离散选择实验的数据，以严格检验影响该国疫苗偏好的因素。 我们发现，疫苗有效性、副作用的存在、保护持续时间、接种中心的距离以及社会网络中的接种率在决定疫苗需求方面起着关键作用。 我们应用了一个非参数模型来揭示这些因素影响的异质性。 我们从这一分析中得出了两个新的见解。 首先，尽管平均而言国产疫苗更受青睐，但样本中有约30%的人更倾向于外国开发的疫苗。 其次，样本中有约15%的人的疫苗偏好对副作用的存在以及同龄群体中的接种率高度敏感。 这些结果为印度疫苗采用的政策辩论提供了见解。 显示英文摘要

摘要： India's mass vaccination efforts have been slow due to high levels of vaccine hesitancy. This study uses data from an online discrete choice experiment with 1371 respondents to rigorously examine the factors shaping vaccine preference in the country. We find that vaccine efficacy, presence of side effects, protection duration, distance to vaccination centre and vaccination rates within social networks play a critical role in determining vaccine demand. We apply a non-parametric model to uncover the heterogeneity in the effects of these factors. We derive two novel insights from this analysis. First, even though, on average, domestically developed vaccines are preferred, around 30 percent of the sample favours foreign-developed vaccines. Second, the vaccine preference of around 15 percent of the sample is highly sensitive to the presence of side effects and vaccination uptake among their peer group. These results provide insights into the ongoing policy debate around vaccine adoption in India.
