We invent for life

Using the power of leading-edge science to save and improve lives around the world.

Our presence in the UK goes back a long way

We’ve been an integral part of the scientific community here for over 100 years. MSD globally has been at the forefront of research, bringing forward medicines, vaccines and innovative health solutions for the world’s most challenging human and animal diseases.

In the United States and Canada, we are known as Merck & Co., Inc., Rahway, N.J., USA, everywhere else we are known as MSD. Although we have two names globally, we are one company with one purpose.
