Life is a health journey, with ups and downs, which can be big or small, lifelong or momentary. We, at Sanofi, are there for those challenges, supporting people as a health journey partner.

As a leading healthcare partner, we provide medicines in several therapeutic areas. We are also active in consumer healthcare, and are Canada’s largest vaccine producer through our Vaccines business unit in Toronto.

Below, you’ll find more information about our key therapeutic areas.

Health & Well-being

We believe that empowering individuals, the community and healthcare professionals to promote and practice self-care will allow people to lead healthier, fuller lives. Our self-care solutions cover allergies, digestive health and pain care.

Multiple Sclerosis

At Sanofi, we have been working for over a decade on the development of treatments for multiple sclerosis (MS). Our R&D efforts remain focused in areas where we believe we have the strongest potential to help patients in need. This includes early-stage programs on preventing and repairing the damage to the nervous system caused by MS.

Rare Diseases

The rarity and complexity of patients’ medical conditions can make a rare disease difficult to diagnose and treat, leaving patients feeling isolated. At Sanofi, we are committed to empowering the lives of people with rare diseases by offering sustainable, transformative healthcare options.

Rare Blood Disorders

Some of our patients’ most serious needs today are in the field of hematology, and we are committed to significantly improving the health and lives of people with rare blood disorders around the world through groundbreaking science.
