How many product groups does Sanofi have? Thank you separately.
Sanofi-Aventis is divided into core business units (mainly in the cardiovascular field, the main products are Polivi, Kesai, Ambovi and Kedarone), diabetes business units (Letty, Amory), internal medicine business units and tumor business units (Taxodi), and Sanofi-Pasteur's main business is relatively independent vaccines.
