US, Hungarian scientists win Nobel Prize for research that led to Covid vaccines

Scientists Katalin Kariko of Hungary and Drew Weissman of the United States respectively won the 2023 Nobel Prize in Physiology or Medicine for discoveries enabling the development of mRNA Covid-19 vaccines, the award-giving body has announced.
“The 2023 Nobel Prize in Physiology or Medicine has been awarded to Katalin Kariko and Drew Weissman for their discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against Covid-19,” the body said on Monday
The prize, among the most prestigious in the scientific world, is selected by the Nobel Assembly of Sweden’s Karolinska Institute Medical University and also comes with 11 million Swedish crowns (about $1 million).
Kariko was senior vice president and head of RNA protein replacement at BioNTech until 2022 and has since acted as an adviser to the company. She is also a professor at the University of Szeged in Hungary and adjunct professor at the University of Pennsylvania’s Perelman School of Medicine.
Weissman is professor in vaccine research at the Perelman School.
Kariko found a way to prevent the immune system from launching an inflammatory reaction against lab-made mRNA, previously seen as a major hurdle against any therapeutic use of mRNA.
Together with Weissman, she showed in 2005 that adjustments to nucleosides, the molecular letters that write the mRNA’s genetic code, can keep the mRNA under the immune system’s radar.
