@drensber @Bob_Wachter @AshishKJha46 There's only 2-2.5 years of experience and after the first year Omicron showed up which definitely reduced protection against severe disease quite a lot. The other data shows some reduction, not remotely to the point of having no immunity, but worse than a recent boost.
@drensber @Bob_Wachter @AshishKJha46 只有 2-2.5 年的经验，并且在第一年 Omicron 出现之后，这无疑大大降低了对严重疾病的保护。其他数据显示有所减少，虽然远没有达到没有免疫力的地步，但比最近的提升还要糟糕。
