MCM Vaccine B.V. (in Europe) and MSP (in the US) were established in 1991 to enable MSD and Sanofi Pasteur to co-develop an hexavalent pediatric vaccine that can combine and deploy the proven antigens developed by each company.

MSD and Sanofi are two of the world’s largest vaccine companies, both with long track records in vaccine and antigen development. They have collaborated for more than 30 years in the US, Europe and Australia, allowing them to pool their extensive experience in developing, manufacturing and marketing combination vaccines.
