We chase the miracles of science so you can chase your dreams.

At Sanofi, our legacy in pursuing life-changing science began more than 50 years ago when we delivered the world’s first polio vaccine. Since that time, our science has continued to set new standards of care and helped bring novel, first- and best-in-class medicines and vaccines to people all over the world. But we believe we can go further.

Our world-class expertise and capabilities are informed by decades of research and development (R&D) and commercial experience. They represent both a unique competitive advantage and an unparalleled opportunity to transform the lives of millions of people urgently waiting for breakthrough innovations.
