Two pioneering scientists who created the technology behind life-saving Covid-19 vaccines have won the Nobel Prize in medicine or physiology.
Dr. Katalin Karikó and Dr. Drew Weissman, both of the University of Pennsylvania, achieved their breakthrough by harnessing the power of genetic material known as messenger RNA, or mRNA. Their discoveries have opened up a new chapter in medicine, paving the way for new vaccines for other infectious diseases, including the flu, and treatments for noninfectious diseases such as cancer. Here are five things to know about Karikó and Weissman’s game-changing research and mRNA vaccines.
However, development of those types of vaccines can be lengthy, and it can be difficult to modify them quickly. Messenger RNA-based vaccine technology doesn’t rely on a modified version of a virus to produce an immune response. It uses modified mRNA to tell the body’s cells to produce proteins that train the immune system to defend the body against a particular disease.
