@WSpunkmeyer @greggwbarnes @benny171a @TrumpUndead @jonathanchait None of that is true. Actual immunity is more subtle and a matter of degree and multiple aspects than absolute immune or not immune. You gain some immunity by recovering from covid, that's why it is usually less severe the next time. But people still get it repeatedly.
@WSpunkmeyer @greggwbarnes @benny171a @TrumpUndead @jonathanchait 这些都不是真的。与绝对免疫或不免疫相比，实际免疫更为微妙，是程度和多方面的问题。通过从新冠病毒中恢复，您可以获得一些免疫力，这就是为什么下次它通常不那么严重的原因。但人们仍然反复得到它。
