Nobel Prize 2023
The Nobel Prize in Physiology or Medicine has been awarded to biochemist Katalin Karikó and immunologist Drew Weissman for discoveries that enabled the development of messenger RNA (mRNA) vaccines against COVID-19. The vaccines have been administered more than 13 billion times, saved millions of lives and prevented severe illness in millions of people. Karikó and Weissman discovered a way to deliver mRNA into cells without triggering an unwanted immune response: by swapping one type of molecule, uridine, in the genetic material with a similar one called pseudouridine.
