About Us


We believe in a world where no one suffers or dies from a vaccine preventable disease. Our vaccines help protect as many as half a billion lives each year against life-threatening infectious diseases at every stage of life. With our 15,000 employees worldwide, we seek to extend the protective power of vaccination to new infectious diseases while continuously improving existing vaccines to enhance health and wellbeing.

We have a diverse portfolio of high-quality vaccines for children, adolescents and adults, including influenza, meningitis, travel and endemic diseases. We are a world leader in influenza and paediatrics vaccines, and the first worldwide supplier of polio injectable vaccine.

To protect and improve human health worldwide by providing superior, innovative vaccines for the prevention and treatment of disease and by playing an active role in the immunisation community to maximise vaccination.

The Heritage of Sanofi Pasteur

The heritage of Sanofi Pasteur1 dates back more than a century, and is closely linked with the achievements of Louis Pasteur, the Mérieux family, John FitzGerald and Richard Slee. Although each followed a unique path, they shared one goal – protecting people from infectious diseases.

Sanofi Pasteur is a truly global company based on innovation, scientific rigor and international synergies. We are proud of our rich heritage and continue to draw inspiration from the legacy of the pioneers who built our foundation.
