What We Do

At Moderna, we believe messenger RNA, or mRNA, is the “software of life.”

Every cell in the body uses mRNA to provide real-time instructions to make the proteins necessary to drive all aspects of biology, including in human health and disease.

Given its essential role, we believe mRNA could be used to create a new category of medicines with significant potential to improve the lives of patients.

We are pioneering a new class of medicines made of messenger RNA, or mRNA. The potential implications of using mRNA as a drug are significant and far-reaching and could meaningfully improve how medicines are discovered, developed and manufactured.
