https://www.sciencedaily.com/releases/2020/07/200716101536.htm https://www.nature.com/articles/s41586-020-2550-z The T cells, along with antibodies, are an integral part of the human immune response against viral infections due to their ability to directly target and kill infected cells. The study by scientists from Duke-NUS Medical School, in close collaboration with NUS, SGH and NCID was published in Nature . The findings suggest infection and exposure to coronaviruses induces long-lasting memory T cells, which could help in the management of the current pandemic and in vaccine development against COVID-19.
