The influenza vaccination uptake rate is low in China. In the current study, we aimed to explore the preferences of influenza vaccination among the Chinese elderly. A discrete choice experiment design was performed to assess their preferences toward five influenza vaccination attributes, including vaccine effectiveness, duration of protection, severe adverse effects, vaccination cost, and vaccination recommendation source. A total of 144 participants aged over 60 years from three cities of Shaanxi province in China were surveyed. A mixed logit model was employed to analyze the data. The elderly population were found to prefer influenza vaccination with a longer duration of protection, followed by lower severe adverse effects, higher vaccine effectiveness, and recommended by healthcare providers. The vaccination cost was the least important attribute. The most considerable marginal willingness to pay for vaccination (CNY220.90) and the highest vaccination choice probability (83.70%) occurred when the duration of protection extended from 3 to 12 months. The present study's findings would inform decision-makers on implementing appropriate interventions for the increase of influenza vaccination coverage among the elderly in China.
中国的流感疫苗接种率较低。在本研究中，我们旨在探讨中国老年人对流感疫苗接种的偏好。采用离散选择实验设计评估了他们对流感疫苗接种的五个属性的偏好，包括疫苗效力、保护持续时间、严重不良影响、接种成本和接种推荐来源。共调查了来自中国陕西省三个城市的 144 名 60 岁以上的参与者。采用混合 Logit 模型对数据进行分析。结果发现，老年人更倾向于接种保护持续时间更长的流感疫苗，其次是严重不良影响较低、疫苗效力较高和由医疗保健提供者推荐的疫苗。接种成本是最不重要的属性。当保护持续时间从 3 个月延长至 12 个月时，接种的边际意愿支付（CNY220.90）最高，接种选择概率（83.70%）最高。本研究的结果将为决策者在中国实施增加老年人流感疫苗接种覆盖率的适当干预措施提供信息。
