T Cells From Common Colds Cross-Protect Against Infection With COVID-19

T cells from common colds cross-protect against infection with COVID-19

A new study, published in Nature Communications and led by Imperial College London researchers, provides the first evidence of a protective role for these T cells. While previous studies have shown that T cells induced by other coronaviruses can recognize SARS-CoV-2, the new study examines for the first time how the presence of these T cells at the time of SARS-CoV-2 exposure influences whether someone becomes infected.

The researchers also say their findings provide a blueprint for a second-generation, universal vaccine that could prevent infectionfrom current and future SARS-CoV-2 variants, including Omicron.

We found that high levels of pre-existing T cells, created by the body when infected with other human coronaviruses like the common cold, can protect against COVID-19 infection.
