作者强调，再次感染这种病毒可能是罕见的，但这研究结果意味着不是每个人都对病毒产生完全的免疫力。因为免疫力永远不会100％。再次感染上冠状病毒似乎极其罕见。 迄今为止，这是美国近600万例病例中的第一例。 此人的两次感染只相隔一个月左右。而疫苗从接种到产生抗体也需要至少一个月时间。这种特殊的例子说明不了什么。 https://www.reuters.com/article/us-health-coronavirus-reinfection/first-u-s-covid-19-reinfection-case-identified-in-nevada-study-idUSKBN25O2L9 They emphasized that reinfection with the virus is probably rare, but said the findings imply that initial exposure to the virus may not result in full immunity for everyone. reinfections are possible - which we already knew, because immunity is never 100%, Reinfection with the coronavirus appears to be rare.

没用没用,回家等死
所以现在在做临床实验的疫苗抗体数据都是高于普通康复者的
那还不错 希望有用
抗体下降的很快，三个月吧。但是还有T细胞免疫，还有记忆B细胞，所以也不能光看抗体数据。
