A controversial scientist who carried out provocative research on making influenza viruses more infectious has completed his most dangerous experiment to date by deliberately creating a pandemic strain of flu that can evade the human immune system.
Yoshihiro Kawaoka of the University of Wisconsin-Madison has genetically manipulated the 2009 strain of pandemic flu in order for it to “escape” the control of the immune system’s neutralizing antibodies, effectively making the human population defenseless against its reemergence.
Most of the world today has developed some level of immunity to the 2009 pandemic flu virus, which means that it can now be treated as less dangerous “seasonal flu”. However, The Independent understands that Professor Kawaoka intentionally set out to see if it was possible to convert it to a pre-pandemic state in order to analyze the genetic changes involved.
