Omicron variant: the planet on alert

The study, published in Nature Communications , concludes that those who had contracted a classic cold had also developed a “bank of memory ” of specific immune cells capable of preventing future infections and making them less vulnerable to Covid.

If the experts insist that this new data is not enough to ignore the vaccine, which remains the only effective protection to date against the virus , they believe that the latter provides useful information on the functioning of the defense system. “We have found that high levels of pre-existing T cells, created by the body when infected with other coronaviruses hum like colds, can protect against COVID infection – 18 ” details Doctor Rhia Kundu, author of the study with the English media Sky News , while emphasizing that coronaviruses only represent 09 at 15% of colds. This would therefore be a “serious error” to think that anyone who has recently caught a cold is automatically protected against Covid – 19, he insists.

In contrast, “learning what the body does correctly could help design new vaccines” , estimates Professor Ajit Lalvani, co-author of the study, specifying that “vaccines that more closely exploit the work of T cells could provide broader protection e t more durable against Covid “.
