Sanofi

Sanofi is a French multinational pharmaceutical company based in Paris. It develops, manufactures, and markets medicines and vaccines for human health, spanning areas such as diabetes, oncology, immunology, and rare diseases. The company operates globally and is one of the world's largest pharmaceutical groups by revenue.

Sanofi traces its origins to a 2004 merger between Sanofi-Synthelabo and Aventis, itself formed from older French and German chemical groups. The combined company adopted the Sanofi name in 2011. Its operations are structured into several segments, including Pharmaceuticals, Vaccines through Sanofi Pasteur, and Specialty Care via Genzyme. Notable historical products include Lantus insulin and Plavix antiplatelet therapy; Sanofi Pasteur remains one of the leading vaccine producers worldwide.

Sanofi Pasteur develops vaccines for influenza, childhood immunizations, and other infectious diseases; Genzyme focuses on rare genetic diseases, multiple sclerosis, and other specialty care areas.

Research and development activities cover immunology, oncology, rare diseases, vaccines, and cardiovascular disease. The company pursues strategic partnerships, notably with Regeneron for Dupixent (dupilumab) and other therapies, and collaborates with other industry players on vaccines and novel therapies. In recent years, Sanofi expanded its portfolio through acquisitions such as Bioverativ to strengthen hematology and pursued pipeline programs in oncology and immunology.

Sanofi operates in more than 100 countries and maintains R&D and manufacturing sites worldwide. It is publicly traded on Euronext Paris and the New York Stock Exchange, and is governed by a board of directors led by a chief executive officer.
