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 share the award for their groundbreaking work in mRNA technology, which they started more than 20 years ago at the University of Pennsylvania.

The Nobel Prize committee said: "The laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times."

Newshour's Tim Franks started by asking them how they felt when they first got the call.
