'Significant number' of people may have some natural immunity to coronavirus

'Significant number' of people may have some natural immunity to coronavirusLarge numbers of the population may have natural immunity against coronavirus even if they have never been infected, scientists believe. Sir John Bell, Regius Professor of Medicine at Oxford University, who is leading an Oxford team to develop a vaccine, said there was likely to be a "background level" of protection for a "significant number of people". Recent studies have suggested the immune system can be primed by other coronaviruses, such as the common cold, giving the body a head start in fighting off Covid-19. Research shows that a separate part of the immune system, T-cells, respond to chains of amino acids produced by different types of coronaviruses and may be responsible for stopping the virus in people who never show symptoms. Crucially, those T-cells die off in older people, which may be why they are far more likely to develop a more serious illness. Speaking to the Commons science and technology select committee, Sir John said: "What seems clear is you do have cross-reaction from T-cells that are activated by standard endemic coronaviruses. I think they are present in quite a significant number of people.
