Sanofi is a French pharmaceutical company formed in 1973 and assembled over five decades through a long series of mergers including Synthelabo, Aventis and Genzyme. It is now built around immunology and rare disease, with Dupixent for atopic dermatitis and asthma as by far its largest product, alongside a substantial vaccines division covering influenza, meningitis and the respiratory syncytial virus antibody Beyfortus. Headquartered in Paris, the group has sharpened its focus in recent years by separating its consumer healthcare business into the standalone company Opella and directing research spending toward biologics and immune science.
