我告诉@MarkHalperin ，这个故事并不是从2020年开始的。安东尼·福奇对功能增益研究的倡导可以追溯到2010年，当时他资助了荷兰的一项研究，该研究在禽流感病毒中引入了八个点突变，使其在哺乳动物之间更具传染性。

I told @MarkHalperin that this story didn't start in 2020. Anthony Fauci's advocacy for gain-of-function research dates back to 2010, when he funded research in the Netherlands that introduced eight-point mutations into bird flu to make it more infectious between mammals. @RandPaul http://t.cn/AXNGct9P
