CNN —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. Rickard Sandberg, a member of the Nobel Prize in medicine committee, said, “mRNA vaccines together with other Covid-19 vaccines have been administered over 13 billion times. They sold their car, Karikó told The Guardian, and stuffed the money – an equivalent of about $1,200 – in their daughter’s teddy bear for safekeeping. Weissman told CNN that their technology is much more efficient than traditional methods of producing vaccines.
