MSD is a trade name of Merck & Co., Inc., with headquarters in Kenilworth, NJ, USA.

With offices in 140 countries, we aim to make a real difference with an innovative range of services and pharmaceutical products which promote and support health and wellbeing.
We produced the first tuberculosis (TB) vaccine in 1944, and continue to bring a number of pioneering medicines in areas such as heart disease and cancer. But it doesn’t stop there. As the healthcare needs of the world evolves, so does our pipeline- with the UK making forward investments in areas such as dementia and antimicrobial resistance.
