This year’s Nobel Prize in physiology or medicine has been awarded to Katalin Karikó and Drew Weissman for their work on mRNA vaccines, a crucial tool in curtailing the spread of Covid-19.
The Nobel Prize committee announced the prestigious honor, seen as the pinnacle of scientific achievement, in Sweden on Monday.
It praised the scientists’ “groundbreaking findings,” which the committee said “fundamentally changed our understanding of how mRNA interacts with our immune system.”
