Dr. Katalin Karikó is a Hungarian-American biochemist, Nobel Laureate (2023), and the scientific architect behind the revolutionary mRNA vaccine technology. Her career is a testament to unyielding perseverance against major obstacles, sustained skepticism, and repeated underfunding from the academic community. Her foundational work on in vitro-transcribed messenger RNA (mRNA) made the effective global fight against the COVID-19 pandemic possible.

Karikó's journey exemplifies the power of conviction over convention. After leaving Hungary in 1985 by selling her family car and sewing the proceeds into her daughter's teddy bear, she spent decades struggling to secure funding for her mRNA research at the University of Pennsylvania. Despite being demoted in 1995 and never being granted tenure, she persistently pursued her belief, eventually meeting Dr. Drew Weissman, with whom she co-discovered the crucial nucleoside modifications that suppress RNA immunogenicity. This breakthrough was the key to unlocking the therapeutic use of mRNA.

The technology resulting from her collaboration with Weissman, for which they hold US patents, was licensed by BioNTech and Moderna and became the basis for their highly effective COVID-19 vaccines. Her contributions to containing the global pandemic have earned her numerous accolades beyond the Nobel, including the Lasker–DeBakey Clinical Medical Research Award and Time Magazine's Hero of the Year 2021. She has since joined the faculty at the University of Szeged as a professor.

As a speaker, Dr. Karikó shares the inspiring, candid story of her unwavering commitment to her research, even when colleagues “laughed at them” and funding was denied. Her narrative, which includes the success of her daughter as a two-time Olympic gold medalist, provides a powerful message on the rewards of perseverance and the profound global impact that can result from dedicated scientific endeavor in the face of long-term failure and doubt.
