某网友现身说法，以自己和家人的新冠经历证明：疫苗不必要，新冠不可怕。他本意并不是求安慰，是为了证明观点，所以大家用这个事情作为案例来分析并无不可。
1）得了新冠，真的是毛毛雨吗？他们一家只是有轻微症状而已（我认为是幸运），当然比起大多数的无症状感染者，又属不幸。也有网友举例附和说自己圈子的患者症状都不严重。但是后面有网友提及自己知道的人因病去世的例子。所以，统计帖子里的病例，这死亡率大体还是在公开的统计数字范围内。所以楼主自身经历并不能证明新冠的不可怕。
2）所谓的ZPACK等江湖秘方，真的管用吗？楼主自己吃药，症状改善，但二者有没有因果关系，这依然存疑。其实就连网友自己也说“可能不需要”。后面有网友说，很多人就吃泰诺和维生素，后来也好了。这至少证明不必用楼主的秘方也一样能好。更不用说那些无症状的感染者，连泰诺和维生素都不用，不也没事？
3）所谓的ZPACK等江湖秘方，有没有副作用？网友说，“现在回头看看可能不需要，不过也没坏处。” 你认为官方批准使用的经过测试的疫苗可能有潜在的副作用，那些你自行服用的那些江湖秘方，你就那么肯定不会有潜在的副作用？
4）得过一次，终生免疫？这是楼主言论里最让我惊讶的一条。疫苗反对者反对疫苗的重要理由之一：病毒不断变异，疫苗跟不上。那么，你对一个变种获得了免疫，怎么就能保证对后来的变种自然免疫呢？
欢迎补充。
Much of the study on the immune response to SARS-CoV-2, the novel coronavirus that causes COVID-19, has focused on the production of antibodies. But, in fact, immune cells known as memory T cells also play an important role in the ability of our immune systems to protect us against many viral infections, including—it now appears—COVID-19.
An intriguing new study of these memory T cells suggests they might protect some people newly infected with SARS-CoV-2 by remembering past encounters with other human coronaviruses. This might potentially explain why some people seem to fend off the virus and may be less susceptible to becoming severely ill with COVID-19.
