Fouchier's H5N1 Gain-of-Function Study (2012)

Ron Fouchier's 2012 creation of airborne-transmissible H5N1 influenza in ferrets ignited a global biosecurity firestorm, with a 50% mortality rate in the modified virus. Proponents claim it advances pandemic preparedness, but opponents argue it risked an accidental bioweapon release. This debate is more intense than even the MMR-autism fraud (#1), as Fouchier's work involves active scientific controversy over safety, while Wakefield's was a complete fabrication.
