@therealrthorat @Robbbie_Strange @StuartMill1776 @TrumpUndead @jonathanchait I don't agree. It was stated from the start that there would likely be variants and need for updates/boosters, as with flu shots. If you only heard they would be perfectly effective forever, you weren't paying attention. Efficacy was stated based on condition at the time.
@therealrthorat @Robbbie_Strange @StuartMill1776 @TrumpUndead @jonathanchait 我不同意。从一开始就说明可能会有变体并且需要更新/增强剂，就像流感疫苗一样。如果您只听说它们将永远有效，那您就没有注意。功效是根据当时的情况而定的。
