Biografi

Katalin Karikó, PhD, is a biochemist and researcher, best known for her contributions to mRNA technology and the COVID-19 vaccines. Karikó and co-collaborator Drew Weissman, MD, PhD, invented the modified mRNA technology used in Pfizer-BioNTech and Moderna’s vaccines to prevent COVID-19 infection.

More than 15 years ago at Penn Medicine, Karikó and Weissman found a way to modify mRNA and later developed a delivery technique to package the mRNA in lipid nanoparticles. This made it possible for mRNA to reach the proper part of the body and trigger an immune response to fight disease.

These laboratory breakthroughs made mRNA safe, effective, and practical for use as a vaccine against COVID. The Pfizer-BioNTech COVID-19 vaccine received FDA approval in August 2021, and the Moderna COVID-19 vaccine has been authorized by the FDA for emergency use.

Karikó is a senior vice president at BioNTech and an adjunct professor of Neurosurgery at the University of Pennsylvania.
