　　Yoshihiro Kawaoka of the University of Wisconsin-Madison is a human. He actually fought against the virus by genetically modifying the h1n1 virus that caused the influenza pandemic in 2009 and "evading" antibodies produced by the immune system. Popular again.

　　Most areas of the world are no longer affected by the 2009 influenza virus. In other words, the virus can be regarded as a low-risk "seasonal flu." However, Hegang deliberately wanted to see if he could transform into the preembryonic state of influenza and analyze the related genetic changes.

　　This study has not yet been published, but some scientists who heard about it were allowed to deliberately delete humans’ only line of defense against this deadly virus.

　　Kaoka has not disclosed the details of the research, but admitted that the research has been completed and will be submitted to a scientific journal. He said the experiment is to monitor whether the H1N1 virus has changed in 2009 to evade the immune system, thereby improving vaccine design.

　　He said in an email: "In order to determine the key areas that allow the 2009 H1N1 virus to evade the immune system, the laboratory chose to evade the immune system virus under appropriate containment conditions." He said: "We are among the viruses isolated in the clinic. Seeing the same changes, it shows that there are viruses in nature that can evade the immune system. We conducted this kind of research to study what happens in nature is meaningful."

　　The scientist said: "Hegang chose a strain of influenza virus that was not cleared by human antibodies in 2009, and repeated it several times until he found a real special virus. He must have succeeded. He used a strain called infection. Sexual virus. Change its nature. If the virus escapes from his laboratory, the people of the world will lose resistance."
