T cells from common cold could help ward off Covid-19, study finds

Experts studied a group of people in September 2020 when fewer people in the UK had been infected.

Some of the body’s defences generated after an infection of the common cold could help to ward off the virus that causes Covid-19, researchers have said.

A small study found that people with high levels of T cells – generated after infection with other coronaviruses such as the common cold – were less likely to catch Covid-19.
