Our Science

We are pioneering a new era in immunology to ignite discovery and advance innovative therapies and vaccines for patients across the spectrum of human disease.

An Ambition to Be the World Leader in Immunology

Our deep expertise in the immune system and legacy of 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 to people all over the world. But we believe we can go further. Redefining immunology as we know it, our immunoscience approach is the bedrock of Sanofi’s research and development (R&D) powerhouse.

Immunoscience: a New Approach in R&D

Immunoscience enables us to apply our deep knowledge and expertise beyond the boundaries of conventional immunology.  It allows us to evaluate pathways of immunity and how they function independent of specific disease or pathology. This approach lays the groundwork for potential first-and best-in-class medicines that can treat a multitude of conditions across therapeutic areas so diverse, they would not have been considered to be related even a decade ago.

Powering immunoscience with artificial intelligence (AI), we are forging collaborations with the best external minds and expertise to augment our capabilities and help us drive innovation even faster. Integrating experiences and insights from patients at every step, we are accelerating the discovery and development of breakthrough medicines that will potentially help prevent and treat many more diseases, and transform more lives at a pace like never before.
