Our Pioneers

Our UK scientists were among the first to develop medicines to treat hypertension, HIV and Hepatitis C amongst others, and we are committed to studying Alzheimer’s disease and addressing health issues such as antimicrobial resistance.

Many pioneers at MSD across the globe have led the way, including legendary scientists :

  • Maurice Hilleman who helped develop more than 40 human and animal vaccines
  • Nobel Prize winner Bill Campbell who together with Dr Mohammed Aziz and others championed the discovery and development of a treatment for river blindness that is being distributed throughout the developing world still today

Of MSD’s human medicines, eight were developed here in the UK.
