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.

Headquartered in Cambridge, Mass., Moderna currently has strategic alliances for development programs with AstraZeneca, Plc. and Merck, Inc., as well as the Defense Advanced Research Projects Agency (DARPA), an agency of the U.S. Department of Defense; and the Biomedical Advanced Research and Development Authority (BARDA), a division of the Office of the Assistant Secretary for Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS). Moderna has been ranked in the top ten of Science's list of top biopharma industry employers for the past four years. To learn more, visit .
