Jonas Salk refused to patent his polio vaccine in 1955. So he lost $7 billion, but he made the drug available to children around the world. Thanks to him, the incidence of the disease has fallen by 96%

Un gesto generoso que cambió la historia. La vacuna de la polio de Jonas Salk salvó millones de vidas al no patentarse. Su impacto perdura hasta hoy.
