Our legacy

A partnership between MSD and Sanofi Pasteur inc. to offer an hexavalent pediatric vaccine.

Sanofi has been a leader in vaccines for more than 100 years.

The combination of our innovative vaccines and global reach means that many diseases do not hold the power they once did. Our determination to improve public health motivates us to develop new vaccines to address still unmet medical needs. Fueled by new data and digital technologies, our science and manufacturing have the potential to transform the practice of medicine for millions of people around the world.
