@PeterDrake125 @TrumpUndead @jonathanchait You're not wrong when you state something that is true at the time and then conditions change.
If you make a prediction like "these vaccines are going to continue to work just as well for 10 years" then you could turn out to be wrong. No one did that as far as I know.
@PeterDrake125 @TrumpUndead @jonathanchait 当您陈述当时正确的事情然后情况发生变化时，您并没有错。
如果您做出诸如“这些疫苗将在 10 年内继续有效地发挥作用”之类的预测，那么您可能会被证明是错误的。据我所知，没有人这样做。
