The chemistry is gone: Sanofi and Merck break-up

Sanofi Pasteur and MSD, known as Merck in the US, announced their intent to end their joint vaccines operations in Europe

Upon concluding their joint venture, both companies plan to integrate their respective European vaccine businesses into their operations, independently manage their product portfolios and pursue their own distinct growth strategies in Europe, according to Sanofi.

The joint venture, Sanofi Pasteur MSD, is owned on a 50/50 basis by Sanofi Pasteur and MSD, was created in 1994 to develop and commercialise vaccines originating from both companies' pipelines to improve and promote public health in 19 European countries.

Over the past twenty years, Sanofi Pasteur MSD has launched numerous vaccines originating from Sanofi Pasteur and MSD's development pipelines.

 Sanofi Pasteur and MSD jointly issued the following statement: "We are proud of Sanofi Pasteur MSD's successful 20-year history.

“Our joint venture has achieved considerable success over the past two decades from a public health and commercial perspective.

“After carefully considering our individual strategic priorities, alongside the economic and regulatory environments for vaccine operations in the European Union, we have mutually agreed that it is in our best interests to manage our vaccine product portfolios independently.

“We believe that focusing our efforts on opportunities unique to our respective companies will better position us to drive growth, execute in a more efficient manner and optimize vaccine coverage.

“By bringing vaccines more rapidly to market, both companies would deliver greater value to all stakeholders."

 Sanofi Pasteur and MSD expect the project to be completed by the end of 2016, subject to local labor laws and regulations and regulatory approvals.
