The Nobel Prize in Physiology or Medicine has been awarded to a pair of scientists who developed the technology that led to the mRNA Covid vaccines.
Professors Katalin Kariko and Drew Weissman will share the prize.
The technology was experimental before the pandemic, but has now been given to millions of people around the world to protect them against serious Covid-19.
The same mRNA technology is now being researched for other diseases, including cancer.
