针对SARS-CoV-2感染的疫苗正在研制中。为了为公众可得性做准备，对一种假设的COVID-19疫苗的可接受性和支付意愿进行了评估，以提供对未来需求预测和定价考虑的见解。方法于2020年4月3日至12日进行横断面调查。健康信念模型（HBM）用于评估接种疫苗和WTP意向的预测因子。结果共收到1159份完整回复。大多数人报告了接种疫苗的明确意图（48.2%），其次是可能意图（29.8%）和可能意图（16.3%）。在HBM的感知利益构建项下，即相信接种疫苗降低感染机会（OR = 2.51, 95% CI 1.19-5.26）和接种疫苗使他们感到更少担心（OR = 2.19, 95% CI 1.03-4.65），被发现具有明确接种疫苗意图的最高显著几率。参与者愿意为一剂COVID-19疫苗支付的金额的平均+/-标准差（SD）为134.0林吉特（SD +/- 79.2）[30.66 +/- 18.12美元]。大多数参与者愿意为疫苗支付100林吉特[23美元]（28.9%）和50林吉特[11.5美元]（27.2%）的金额。疫苗的较高边际WTP受到无负担障碍以及社会经济因素（如高等教育水平、专业和管理职业以及较高收入）的影响。结论HBM结构在理解COVID-19疫苗接种意向和WTP方面具有实用价值。
Background The development of a vaccine against SARS-CoV-2 infection is on the way. To prepare for public availability, the acceptability of a hypothetical COVID-19 vaccine and willingness to pay (WTP) were assessed to provide insights into future demand forecasts and pricing considerations. Methods A cross-sectional survey was conducted from 3 to 12 April 2020. The health belief model (HBM) was used to assess predictors of the intent to receive the vaccine and the WTP. Results A total of 1,159 complete responses was received. The majority reported a definite intent to receive the vaccine (48.2%), followed by a probable intent (29.8%) and a possible intent (16.3%). Both items under the perceived benefits construct in the HBM, namely believe the vaccination decreases the chance of infection (OR = 2.51, 95% CI 1.19-5.26) and the vaccination makes them feel less worry (OR = 2.19, 95% CI 1.03-4.65), were found to have the highest significant odds of a definite intention to take the vaccine. The mean +/- standard deviation (SD) for the amount that participants were willing to pay for a dose of COVID-19 vaccine was MYR$134.0 (SD +/- 79.2) [US$30.66 +/- 18.12]. Most of the participants were willing to pay an amount of MYR$100 [US$23] (28.9%) and MYR$50 [US$11.5] (27.2%) for the vaccine. The higher marginal WTP for the vaccine was influenced by no affordability barriers as well as by socio-economic factors, such as higher education levels, professional and managerial occupations and higher incomes. Conclusions The findings demonstrate the utility of HBM constructs in understanding COVID-19 vaccination intention and WTP.
