Formed as Sanofi-Aventis in 2004, the global and diversified healthcare leader focuses on six growth areas including healthcare, vaccines, innovative products, emerging markets, diabetes, and animal health. Its products are centred on oncology, diabetes, cardiovascular, CNS, vaccines, thrombosis and internal medicines. Although predominantly a manufacturer of prescription drugs, it has also established itself in over-the-counter medicines. The company reinforced its commitment to research rare diseases through its Genzyme acquisition, and remains the largest producer of vaccines via its subsidiary Sanofi Pasteur. In 2011 the pharmaceutical company, which is headquartered in Paris, dropped Aventis from its name to become Sanofi.
