@princessresist @jklmd123 @CDCgov Even before Omicron the vast majority of breakthroughs were later in the year. Delta plus waning immunity. So all of those summaries that go way back were very misleading (including covering a period when not many were even vaccinated).
@princessresist@jklmd123@CDCgov即使在Omicron之前，绝大多数突破都是在今年晚些时候实现的。Delta加上免疫力下降。因此，所有这些可以追溯到很久以前的总结都具有误导性（包括涵盖了一段甚至没有多少人接种疫苗的时期）。
