Maini compares the way these memory T cells might quickly attack SARS-CoV-2 to driving a car. In most cases, the genes affect receptors that the viruses must latch onto in a cell, rendering them difficult for the viruses to bind to. But the UCL team carried out further tests on hundreds more blood samples collected as far back as 2011, long before the pandemic struck, and discovered that about one in 20 also had antibodies that could destroy Covid.

So far the booster programme is a roaring success, with more than half the population receiving a vital third dose offering at least 70 per cent protection against symptomatic infection with Omicron. Whether some people are at greater or lesser risk of infection with SARS-CoV-2 because of a prior history of exposure to coronaviruses is an open question. Until now, there has not been a formal definition for this condition. Some people might be genetically resistant to COVID-19, new study says As the drive towards a vaccine against the new coronavirus accelerates, there's some good news: People with COVID-19 have robust immune responses against the virus, scientists say.
