EVERY year the Nobel Prize is awarded to people who have done outstanding work in their fields – and this year two scientists whose research led to the development of the Covid-19 vaccine received the prize for physiology or medicine.
Hungarian biochemist KATALIN KARIKÓ and American immunologist DREW WEISSMAN met in a hallway at university in 1997 while trying to make prints of documents. The pair struck up a friendship that led to more than 20 years of collaborating on research into how messenger RNA (mRNA) works and how it interacts with our immune system.

HOW DOES IT WORK?
Vaccines are traditionally made from weakened or inactive versions of a virus, which are then injected into humans. This means that when you contract the virus, you
