Why have some people never had Covid and can that lead to better vaccines?
However, I have never tested positive despite:Driving to a grim car park for a PCR test or taking a lateral flow whenever I had symptomsProf Maini concludes: "Put together with your negative anti-N antibody test, it suggests you may be someone who has escaped a full-blown infection.The idea of an abortive infection is you are exposed to the virus, it even gets into the right places to start an infection, but the body gets on top of it before it takes off.
The other half of the immune system is known as the adaptive immune system, which learns and gets better with practice. This is how vaccines prepare the body for fighting Covid. Even before the first cases arrived in the UK, some people had these anti-Covid soldiers in their bodies. They are probably the result of catching other common cold coronaviruses, which are closely related to the Covid virus.
"If you could make T-cells against the inner regions of the virus and get those responses in the nose, airways and lungs there's a much better chance they could abort the infection before it takes off, that's the goal," says Prof Maini.
