Covid-19: Common cold may give some protection, study suggests

Natural defences against a common cold could offer some protection against Covid-19, too, research suggests.

The small-scale study, published in Nature Communications, involved 52 individuals who lived with someone who had just caught Covid-19.

Those who had developed a “memory bank” of specific immune cells after a cold - to help prevent future attacks - appeared less likely to get Covid.

Experts say no-one should rely on this defence alone, and vaccines remain key.

But they believe their findings could provide useful insight into how a body’s defence system fights the virus.
