Scientists win medicine Nobel for mRNA vaccine work

STORY: 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 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.

The medicine prize kicks off this year's awards with the remaining five to be unveiled in the coming days.
