Successful vaccine promotion communication strategies require knowing how eligible recipients will respond to the opportunity to get vaccinated. Two main classes of recipients are myopic rationalists, those who receive a dose of vaccine only if it maximizes their own instant benefit and if so, do it as soon as possible, and success-based learners, those who learn from others that they perceive to be most successful.
A recent study models these two decision-making types, and estimates the population proportion of myopic rationalists in each U.S. state. In this report, we fit a similar model to data on COVID-19 vaccine uptake across the Canadian provinces and territories.
We estimated that 64% of Canadians behaved as myopic rationalists in taking the first dose of a COVID-19 vaccine, compared to an estimated 47% in the United States. Among the provinces, the lowest proportion of myopic rationalists was 0.51 in Saskatchewan, while the highest was 0.74 in Prince Edward Island. The correlation analysis suggested a positive correlation between the proportion of myopic rationalists and the average age across the Canadian provinces (Pearson- = 0.71).
Canadian health management may benefit from these results in tailoring the vaccine promotion communication strategies.
成功的疫苗推广沟通策略需要了解符合条件的接种者对接种疫苗机会的反应方式。主要有两类接种者，一类是目光短浅的理性主义者，即只有在接种疫苗能使自身即时利益最大化时才会接种一剂疫苗，并且一旦如此就会尽快接种；另一类是基于成功经验的学习者，即从他们认为最成功的人那里学习经验的人。
最近的一项研究对这两种决策类型进行了建模，并估计了美国每个州目光短浅的理性主义者的人口比例。在本报告中，我们对加拿大各省和地区的新冠疫苗接种数据拟合了一个类似的模型。
我们估计，64%的加拿大人在接种第一剂新冠疫苗时表现为目光短浅的理性主义者，而在美国这一比例估计为47%。在各省中，目光短浅的理性主义者比例最低的是萨斯喀彻温省，为0.51，最高的是爱德华王子岛省，为0.74。相关性分析表明，加拿大各省目光短浅的理性主义者比例与平均年龄之间存在正相关（皮尔逊相关系数 = 0.71）。
这些结果可能有助于加拿大的卫生管理部门制定更有针对性的疫苗推广沟通策略。
