You may know one. You may be one of them - the lucky few who have never had Covid despite not being vaccinated. Now we are more than two years into the pandemic, these people could give us greater insight into how to combat the virus and other pandemics in future.

Coronavirus first hit the UK at the start of 2020 and is still with us today. But unlike two years ago, it is now regarded as being mainly under control, thanks to the vaccine programme. So far, the virus has killed more than 180,000 people and infected 22.7 million people in the UK.
