Dr Katalin Kariko
She is a biochemist and researcher, best known for her contributions to mRNA technology and the COVID-19 vaccines. Karikó invented the modified mRNA technology used in Pfizer-BioNTech and Moderna’s vaccines to prevent COVID-19 infection. She also 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
