As fears grow on the eve of returning to school, a study has found that children are more resistant to COVID-19 due to their faster immune response to infection.

Children, they have much more receptors within cells that are able to notice the presence of foreign RNA. The fact that there are so many of them right away, it’s as if the children’s immune system within the cells was already realizing that something had to be done, said Dr. Elie Haddad, head of pediatric immunology and rheumatology. In CHU Sainte-Justine, interview at LCN.
In short, this means that children’s immune system responds to infection more quickly than it does adults. By doing this, children have a more effective response to combating coronavirus disease, as well as reducing the length of time they are carriers of the virus.
We already knew that children are less sick. But there it is, explains how it works. “In other viral infections, it is less important because there is no point in preparing for it,” said Dr. Haddad.
“What you need to know is that this SARS-CoV-2 is incredible. It is capable on its own [d’arrêter] Intracellular immune response. That’s what he does with the adults, but he doesn’t have time with the kids because they were already ready.”
So it’s a bit like a race against time in the nose before the virus progresses to the lungs, where the disease becomes more serious.
Why vaccinate children?
Despite this larger immune response, experts still believe it’s best to vaccinate children against COVID-19.
“Although they do not have the serious form of the disease, if we come to a pandemic in which more and more children are affected, […] Dr. Elie Haddad summed up the fact that the more contagious the virus, the more affected children will be.
He says this is a decision based on calculating the benefits risks.
“We believe that children should be vaccinated to protect them and the rest of society,” he noted.
