Biography
Katalin Karikó was born on January 17, 1955, in Szolnok, Hungary. She went to Móricz Zsigmond Gimnázium és Közgazdasági Szakközépiskola and then continued her education at the University of Szeged, where she completed her undergraduate and graduate studies. She focused on biochemistry, particularly RNA mechanisms and their potential for therapy.
Karikó faced many challenges and eventually made breakthrough discoveries in her professional career. In 1995, she was demoted by the University of Pennsylvania due to underfunding and skepticism about her mRNA research and never got tenure there. Despite these obstacles, she persisted in researching RNA-mediated immune activation. Her work with American immunologist Drew Weissman led to the co-discovery of nucleoside modifications that reduce RNA immunogenicity, which became crucial for therapeutic mRNA applications.
Between 2006 and 2013, Karikó co-founded and was CEO of RNARx, showing her entrepreneurial efforts to push RNA research forward. She then joined BioNTech RNA Pharmaceuticals in 2013, where she advanced from vice president to senior vice president by 2019. She stayed with BioNTech until 2022, when she left to focus more on research.
Karikó's research became globally important during the COVID-19 pandemic, as her mRNA technology was used in vaccines developed by BioNTech and Moderna. Her work with Weissman resulted in U.S. patents for non-immunogenic, nucleoside-modified RNA uses, licensed by major pharmaceutical companies for COVID-19 vaccines and broader protein replacement therapies. In 2021, she received an honorary doctorate from the University of Szeged and became a professor there, returning to her Hungarian academic roots.
Karikó's contributions to science have been widely acknowledged, leading to the 2023 Nobel Prize in Physiology or Medicine, which she shared with Drew Weissman. She has received numerous awards, including the Rosenstiel Award (2020), Széchenyi Prize (2021), Princess of Asturias Award for Technical and Scientific Research (2021), and the Breakthrough Prize in Life Sciences (2022). These honors highlight the worldwide recognition of her role in pioneering mRNA vaccine technology.
Before Fame
Growing up in communist-era Hungary, Karikó went to school when political and economic constraints made scientific research difficult. During the Cold War, limited international collaboration and restricted access to Western scientific resources made her later accomplishments even more remarkable given these early challenges.
Her rise to prominence began with her determination to pursue RNA research, despite institutional resistance. Many in the scientific community initially viewed mRNA as unstable and impractical for therapeutic use, which led to years of underfunding and professional setbacks. Her persistence through these challenges, including a demotion at the University of Pennsylvania, ultimately allowed her to make groundbreaking discoveries that revolutionized vaccine development and therapeutic medicine.
