晨起，迷迷糊糊，扫过一篇报道。咋看，觉得是好消息。闭眼一想，有点不对劲。再琢磨，毛骨悚然。

标题：Pfizer vaccine only slightly less effective against key South African mutations - study
从标题看，是个好消息: vaccine will still work against these new variants.
下面一段文中提到怎么得出这个结论的：用疫苗接种者身上诱导出来的抗体对病毒的中和滴定度来评估其有效性。
"Pfizer Inc and BioNTech's COVID-19 vaccine appeared to lose only a small bit of effectiveness against an engineered virus with three key mutations from the new coronavirus variant found in South Africa，according to a laboratory study conducted by the U.S. drugmaker.
The study by Pfizer and scientists from the University of Texas Medical Branch (UTMB), which has not yet been peer-reviewed, showed a less than two-fold reduction in antibody titer levels, indicating the vaccine would likely be effective in neutralizing a virus with the so-called E484K and N501Y mutations found in the South African variant.
The study here was conducted on blood taken from people who had received the vaccine. "
可扣细节，看到大坑了："an engineered virus with three key mutations from the new coronavirus variant found in South Africa"
所用的病毒是按南非变种，人工合成的！！！
更糟的是，作者们滋滋不倦的还要接着合成
"The scientists are currently engineering a virus with the full set of mutations and expect to have results from that in around two weeks, according to Pei-Yong Shi, an author of the study and a professor at UTMB."
.........
"The study also showed even better results against several key mutations from the highly transmissible UK variant of the virus. Shi said they were also working on an engineered virus with the full set of mutations from that variant as well."
俺就搞不明白，这位'德大'（UTMB)的“Shi"到底咋想的呢？难道没看到武汉那个水深火热中的“石”？
还是想要证明其实验室比“石”厉害，有本事整出各种病毒？！
可万一，脑子一迷胡，手抖了一下，加错点啥，或按差了键，整出些更邪乎的新变种。
再不小心逛街时放个屁，嘣出来几个……………
这世界岂不更精彩。
这秧秧大国，咋就没人管这事呢？
请德大的朋友，转告那位Shi:
一念天堂 一念地狱 (the difference between heaven and hell lies in your way of thinking)
阿弥陀佛
