How B cells recognise new variants of SARS-CoV-2

The so-called B cells are part of the immune system’s memory. Their memories of previous infections or vaccinations provide the template for antibodies that have a protective effect the next time they come into contact with a pathogen. Researchers at TWINCORE, Centre for Clinical and Experimental Infection Research, have now been able to show that the combination of infection and subsequent vaccination in the case of the SARS-CoV-2 coronavirus even protects against future variants of the virus by the memory cells virtually predicting the future. The team describes how this works in the „European Journal of Immunology“.
