Former CDC director slams gain-of-function research: ‘Probably caused the greatest pandemic’ in history

Former Centers for Disease Control and Prevention (CDC) director Robert Redfield, a virologist, slammed gain-of-function research as not worth the risk during the House’s hearing on the origins of COVID-19.

Redfield appeared in a Wednesday panel in front of the House COVID origins select committee, where he blasted the controversial research method, saying he is not aware it has ever created a treatment or "life-saving vaccines."

"No, on the contrary, I think it probably caused the greatest pandemic our world has seen," Redfield told committee chairman Brad Wenstrup, R-Ohio, who asked if gain-of-function research has ever stopped a pandemic.
