Impossible not to imagine Andrea Pfeifer facing the Cerro Torre. Located in Patagonia, at the confluence of Argentina and Chile, this mythical summit has long been refused to mountaineers. To get there, you have to cross an 800-meter granite wall which leads to the ice cap that tops the summit.
The summit that the German researcher has been challenging for the past twenty years is called alzheimer’s. At the head of the Lausanne-based company AC Immune, which she founded in 2003, Andrea Pfeifer is pushing hard to make the disease capitulate. According to the latest WHO estimates, the scourge affects 30 to 35 million people worldwide.
