This Registered Report attempted to conceptually replicate the finding that communicating herd immunity increases vaccination intentions (Betsch, et al., 2017, Nat. Hum. Behav., 0056). An additional objective was to explore the roles of descriptive social norms (vaccination behaviour of others) and the herd-immunity threshold (coverage needed to stop disease transmission).

疫苗接种的社会推动：交流畜群行为如何影响疫苗接种意图

这份注册报告试图从概念上复制这一发现，即传达群体免疫会增加疫苗接种意图（Betsch 等人，2017 年，Nat. Hum. Behav ., 0056）。另一个目标是探索描述性社会规范（他人的疫苗接种行为）和群体免疫阈值（阻止疾病传播所需的覆盖范围）的作用。
