Sanofi

Sanofi is a global biopharmaceutical company headquartered in Paris, France, with a long history and broad impact in medicines, vaccines, and health innovation. The company was formed through a series of mergers: originally established in 1973, then merging with Synthélabo in 1999, later with Aventis in 2004 to become Sanofi-Aventis, and reverting to simply Sanofi in 2011. Over the decades, it has grown both organically and through acquisition, becoming one of the largest pharmaceutical firms in the world. Sanofi’s operations span numerous therapeutic areas including immunology, oncology, rare diseases, vaccines, diabetes, cardiovascular, central nervous system disorders, internal medicine, and thrombosis. Through its vaccine division, Sanofi Pasteur, it is one of the largest vaccine producers globally. Its research & development programs encompass dozens of compounds in clinical development, and it deploys both internal labs and collaborative partnerships to drive innovation. The company has increasingly adopted AI and digital tools to accelerate discovery, improve efficiency, and enhance patient outcomes.

Sanofi operates in many countries around the world, covering manufacturing, clinical trials, regulatory affairs, marketing, and distribution. It employs tens of thousands of people (over 80,000 globally), with facilities for production, packaging, and research in dozens of countries. Its market presence is extensive, with its medicines and vaccines reaching patients in developed and emerging economies alike. The company balances regulatory compliance, safety, and scientific rigor with the demands of commercial performance. Like many major pharmaceutical companies, Sanofi faces challenges such as high R&D costs, regulatory barriers, competition (especially from generics and biosimilars), pricing pressures, public scrutiny over safety and pricing, and the constant need for innovation. Still, it has a strong financial base with revenues in the tens of billions of euros, substantial assets, and a solid pipeline of future products. Its focus in recent years has also included sustainability, corporate responsibility, environmental impact reduction, and aligning more with global health needs such as vaccines, neglected diseases, and access to medicines.

Strategically, Sanofi aims to go further and faster for patients—accelerating its research, sharpening its focus on breakthrough science, and expanding its impact through partnerships, acquisitions, and internal growth. The company is investing in rare diseases, immunology, and oncology, among other areas, to bring novel therapies to market. It has reorganized its portfolio over time to exit or reshape less-core businesses and emphasize high-growth, high‐impact areas. Sanofi also emphasizes sustainability and ethics in its operations—minimizing environmental footprints, improving access, ensuring governance and compliance, and striving for transparency with stakeholders. In an environment of rising global health challenges, accelerating demand for vaccines, aging populations, and increasing expectations for innovation, Sanofi is positioning itself as a major player not only in pharmaceuticals and vaccines but also in how medicine is researched, manufactured, and delivered in an increasingly interconnected world.
