We aspire to be the premier research-intensive biopharmaceutical company in the world.

For more than 125 years, Merck (known as MSD outside of the U.S. and Canada) 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.

We demonstrate our commitment to patients and population health by increasing access to health care through far-reaching policies, programs and partnerships.

Today, we continue 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.
