National Medical Science Liaison Awareness and Appreciation Day – March 27, 2025

National Medical Science Liaison Awareness and Appreciation Day is marked on March 27 annually. All Medical Science Liaisons from all across the world should be recognized on this special day. Medical Science Liaisons are medical professionals generally linked with the Medical Affairs Departments of pharmaceutical and technology corporations. The majority of them have an extensive background in science and academic credentials, with the majority holding a doctorate in the biological sciences. Find out more about why these sometimes unsung heroes need to be appreciated.

History of National Medical Science Liaison Awareness and Appreciation Day

Initially established by Upjohn Pharmaceuticals in 1967, in response to the need for scientifically trained field personnel who would be able to establish rapport with Key Opinion Leaders in a variety of therapeutic areas of research, Medical Science Liaisons have grown to become a global organization.

Upjohn Pharmaceuticals required field personnel to create ties with prominent medical practitioners to have more meaningful discussions with these external specialists (as well as other healthcare providers) and other stakeholders. The corporation then recognized sales representatives with significant scientific understanding and the ability to deliver a higher level of clinical and educational skills to the medical professionals with whom they were interacting as potential sales representatives. Over the years, medical science liaison teams gained popularity among pharmaceutical corporations due to their effectiveness. During the 1990s, as the size of commercial sales forces grew, the number of medical scientific liaison teams grew at a modest and constant pace. Continued development and growth of field medical programs are necessary due to technological advancements, consolidation of decision-making, and the increasing sophistication of health care decisions.

Even though Upjohn originally referred to the position as Medical Science Liaisons, over the years and into the present, companies have used a variety of names for the position, including ‘Medical Liaisons,’ ‘Medical Managers,’ ‘Regional Scientific Managers,’ ‘Clinical Liaisons,’ and ‘Scientific Affairs Managers,’ to name a few.
