Common-cold-induced T cells protect against SARS-CoV-2 infection

T cells from common colds caused by coronaviruses can further protect against COVID-19, as researchers demonstrate that higher levels of these T cells mean SARS-CoV-2 infection is less likely. 

A study by researchers from Imperial College London (UK), led by Rhia Kundu, set out to investigate the effect of T cells from common coronavirus infections, such as the common cold, on SARS-CoV-2 infection. The group found that when these common cold T cells are present at the time of SARS-CoV-2 exposure, they can protect against COVID-19 infection. The findings demonstrate a potential new vaccine target capable of mimicking this T cell protection to prevent infection against current and future SARS-CoV-2 variants.
