Merck & Co., Inc. is a global research-driven pharmaceutical company dedicated to putting patients first. Established in 1891, Merck currently discovers, develops, manufactures and markets vaccines and medicines to address unmet medical needs. The Company devotes extensive efforts to increase access to medicines through far-reaching programs that not only donate Merck medicines but help deliver them to the people who need them. Merck also publishes unbiased health information as a not-for-profit service.
Merck & Co., Inc. is headquartered in Whitehouse Station, N.J. (USA), and operates as Merck Sharp & Dohme (MSD) in most countries outside the United States.
Since the Company was founded, Merck researchers have pioneered innovations for treating serious diseases - a tradition that has produced such major medical advances as cortisone for rheumatoid arthritis, streptomycin for tuberculosis, statins for cholesterol management and protease inhibitors for HIV/AIDS, to name a few. Merck also has been at the forefront of vaccine research since the early 20th century, discovering vaccines to prevent diseases such as measles, mumps, rubella, chickenpox, hepatitis B, rotavirus, shingles and cervical cancer.
Today, many of our major products are market leaders in their categories. We also remain one of only a few major vaccine manufacturers, compared with the number of companies that invested in vaccine research 30 years ago.
Our long-standing record of achievement continues as Merck scientists work to develop novel treatments in critical areas such as diabetes, obesity, Alzheimer's disease, coronary heart disease, pain, cancer and novel vaccines.
