T cells triggered by common cold also fend off Covid: Study

TIMES OF INDIA:

High levels of protective immune cells that fight some common colds also made people less likely to contract Covid-19 in a study.

Researchers found higher levels of T cells against certain colds in people who didn’t develop Covid while living with someone who had the disease, according to a study released Monday by the U.K.’s Imperial College London. The prior illnesses were caused by other coronaviruses related to SARS-CoV-2.

The findings, published in the journal Nature Communications, provide further evidence of the protective effects of T cells, an arm of the immune system that’s gaining attention as the pandemic stretches into its third year and new variants like omicron erode vaccine protection.
