@Lukewearechange @apagut Maybe it has to do with continuing to use a vaccine for a virus that hasn't been seen in almost two years and has never been updated despite claims these vaccines would be easy to update.
We're relying on residual cross immunity. It sort of works, but not all that effective.
@Lukewearechange@apagut可能与继续使用一种病毒疫苗有关，这种病毒近两年未见，而且从未更新过，尽管声称这些疫苗很容易更新。
我们依靠的是残余交叉免疫。这有点效果，但不是那么有效。
