About Us

The desire to remain in good health connects us all. At Sanofi Pasteur MSD, we believe that vaccination is a way to move Europe forward towards a future where people can stay ahead of disease. Vaccines are our passion because we know that they are the key to a world in better health.
We are dedicated to individual and public health and we stand for equal access to vaccines for all. In developing vaccines across Europe, we are committed to being a trusted partner to policy makers, authorities, experts, healthcare professionals and those using our vaccines. We strive to understand the needs and expectations of all of our stakeholders, and our actions are driven by the common goals we share.

How We Work

We are dedicated to the highest level of scientific excellence and quality standards in developing, producing, delivering and monitoring our vaccines. We hold ourselves to the highest ethical standards, based on respect and transparency, when describing the properties, benefits and potential risks of our vaccines. The safe use of our vaccines is of utmost importance to us, and our teams constantly work on minimising risk and maximising benefits for you.

The integrity, knowledge, experience, competence, initiative and commitment of our employees is the key to our success. We work to create an environment of mutual respect, encouragement and teamwork, where people can do what they love and be rewarded for their performance.

A Joint Venture Between Two Global Leaders


Sanofi Pasteur MSD was formed in 1994 as a unique joint venture between two leaders in biomedical innovation: Sanofi Pasteur, the vaccine division of Sanofi, and Merck, the pharmaceutical company known as MSD outside the US and Canada.

Where We Are

Headquartered in Lyon France, our collaborative structure allows us to draw upon the leading research and manufacturing capabilities of Sanofi Pasteur and Merck, with the passion and focus of a smaller organization dedicated to the needs of a single region. If you are looking for more information about vaccines and vaccination where you live, visit Our Presence page.
