Who do these guys think they are, the Dr. Frankensteins of virology?
First, two teams of virologists created more dangerous versions of the deadly H5N1 flu. Now they want to give the H7N9 virus, which has already sickened at least 134 people and killed 43 people in Asia, a few new capabilities: drug resistance, faster transmission between people and the ability to sneak past the immune system.
