A leading immunologist has outlined four main reasons why some people are immune to coronavirus.
Dr Cliona O'Farrelly revealed that socio-economic backgrounds, general good health, careful behaviour, and a rare innate immune response all play a part in immunity to Covid-19. Dr O'Farrelly said: "How people live has got a lot to do with their circumstances and then on top of that then is this percentage of people who have what we would call an innate immune signature, that's what we're looking for.
"The innate immune signature that identifies the resistance so I think those four things are really important."
