@Nutmeg031992 @LongDesertTrain There wasn't much acceleration, probably a month or two. The main thing that actually happened was it hit a wall of antivax (and some hesitancy) resistance sooner. That's why Biden's goal of 70% was missed despite ample supplies.
@肉豆蔻031992@LongDesertTrain没有太大的加速度，可能是一两个月。实际发生的主要事情是，它更快地撞上了反瓦克斯（以及一些犹豫不决的）抵抗之墙。这就是为什么尽管供应充足，拜登仍未能实现70%的目标。
