@AusThinkingGirl @taipan168 @covidtweets Every society that undertook mitigation in 2020 could have changed course at any point if vaccines became less likely. That never happened. At every step vaccine progress was favorable, and timeline was maintained or accelerated. That certainly informed policies.
@AusThinkingGirl @taipan168 @covidtweets 如果疫苗变得不太可能，每个在 2020 年采取缓解措施的社会都可能随时改变路线。从未发生过。疫苗的每一步进展都是有利的，时间线保持或加快。这肯定会通知政策。
