× Scientists, including one of Indian-origin, have found that people with severe Covid-19 are left with more of the immune system s protective memory T cells needed for fighting reinfection with the novel coronavirus.
The study, published in the journal Science Immunology, assessed the expression of individual genes of a subset of T cells isolated from both Covid-19 patients and non-exposed donors.
