In absence of a COVID-19 vaccine, testing, contact tracing and social restrictions are among the most powerful strategies adopted around the world to slow down the spread of the pandemic. Citizens of most countries are suffering major physical, psychological and economic distress. At this stage, a safe and effective COVID-19 vaccine is the most sustainable option to manage the current pandemic. However, vaccine hesitancy by even a small subset of the population can undermine the success of this strategy. The objective of this research is to investigate the vaccine characteristics that matter the most to Australian citizens and to explore the potential uptake of a COVID-19 vaccine in Australia. Through a stated preference experiment, preferences towards a COVID-19 vaccine of 2136 residents of the Australian states and territories were collected and analysed via a latent class model. Results show that preferences for mild adverse cases, mode of administration, location of administration, price and effectiveness are heterogeneous. Conversely, preferences for immediacy and severe reactions are homogeneous, with respondents preferring a shorter period until vaccine is available and lower instances of severe side effects. The expected uptake of the vaccine is estimated under three different scenarios, with the value of 86% obtained for an average scenario. By calculating individual preferences, the willingness to pay is estimated for immediacy, effectiveness, mild and severe side effects.
在没有 COVID-19 疫苗的情况下，检测、接触者追踪和社会限制是全球范围内减缓大流行传播最有效的策略之一。大多数国家的公民都在遭受严重的身体、心理和经济痛苦。在现阶段，安全有效的 COVID-19 疫苗是管理当前大流行的最可持续选择。然而，即使是一小部分人口对疫苗的犹豫也可能破坏这一策略的成功。本研究的目的是调查对澳大利亚公民最重要的疫苗特征，并探讨澳大利亚 COVID-19 疫苗的潜在接种情况。通过一项陈述偏好实验，收集了澳大利亚各州和地区 2136 名居民对 COVID-19 疫苗的偏好，并通过潜在类别模型进行了分析。结果表明，对轻度不良反应病例、管理方式、管理地点、价格和有效性的偏好存在异质性。相反，对即时性和严重反应的偏好是同质的，受访者更倾向于在疫苗可用之前的时间更短，并且严重副作用的发生率更低。根据三种不同的情况估计了疫苗的预期接种率，平均情况下的接种率为 86%。通过计算个人偏好，估计了对即时性、有效性、轻度和重度副作用的支付意愿。
