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 neutralising antibodies, effectively making the human population defenceless 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”.
The study is not published, however some scientists who are aware of it are horrified that Dr Kawaoka was allowed to deliberately remove the only defence against a strain of flu virus that has already demonstrated its ability to create a deadly pandemic that killed as many as 500,000 people in the first year of its emergence.

The experiment was designed to monitor the changes to the 2009 H1N1 strain of virus that would enable it to escape immune protection in order to improve the design of vaccines, Kawaoka said.
