For more than 125 years, MSD has been inventing for life, bringing forward medicines and vaccines for many of the world's most challenging diseases in pursuit of our mission to save and improve lives. MSD is a trade name of Merck & Co., Inc., with headquarters in Kenilworth, N.J., U.S.A.


Through the years, our researchers have helped to find new ways to treat and prevent illness. During the first nine months of WWII, MSD was the only company prepared to supply dried plasma to the armed forces. This development saved thousands of men’s lives and was one of the outstanding medical contributions to the war effort.

The company discovered vitamin B1 and began producing penicillin “G” in 1942, as well as the first measles vaccine, the most widely prescribed statins to treat high cholesterol and the first anti-cancer vaccine.

We demonstrate our commitment to patients and population health by increasing access to healthcare through far reaching policies, programs and partnerships. Today, MSD continues to be at the forefront of research to prevent and treat diseases that threaten people and animals — including cancer, infectious diseases such as HIV and Ebola, and emerging animal diseases — as we aspire to be the premier research-intensive biopharmaceutical company in the world.
