Patients suffering from severe respiratory symptoms due to the novel coronavirus infection can rapidly generate an immune response in the form of virus-attacking T cells, suggests a new study which may lead to new vaccine development strategies against Covid-19.
The study, published in the journal Science Immunology, assessed T cells from 10 Covid-19 patients under intensive care treatment.
According to the researchers, including those from the University of California in the US, two out of 10 healthy individuals without prior exposure to the virus also harbored SARS-CoV-2-reactive T cells.
Based on this observation, they said these T cells may be cross-reacting to the
