London: People who have high levels of T cells caused by the common cold-causing corona virus are less likely to be infected with SARS-CoV2, the form that causes the COVID-19 disease. This has been claimed in a new study conducted in Britain led by researchers of Indian origin. The research report, published in the journal ‘Nature Communications’, claims that for the first time evidence has been made available about the protective role of T cells.
The study was carried out by researchers from Imperial College London. Another earlier study said that T cells induced by other coronaviruses can identify the virus named SARS-CoV-2, which is responsible for Kovid-19. But a new study has described how the presence of T cells affects infection with SARS-CoV-2.
The researchers hope that their results will play an important role in the development of a second-generation universal vaccine. These universal vaccines may provide protection against current and future forms of the virus responsible for the COVID-19 disease.
Professor Ajit Lalwani, Director of the National Institute for Health Research (NIHR) at Imperial College London, said: “Our research provides the clearest evidence so far that T cells induced by the common cold-causing corona virus (SARS-CoV)- 2 play a protective role against infection.
