44% of children immunized without having been infected

Two scientific studies confirm what the statistics have been telling us for months. Children are not, except in exceptional circumstances, at risk from Covid-19. ” Two studies recently published in leading scientific journals suggest that many children have developed immunity to the virus without being infected with it. The first, published on November 6 in the review Science, estimates that 44% of children have developed effective antibodies against Covid-19 without even having been infected. British researchers claim that exposure to other coronaviruses led their bodies to develop an effective immune response against the new coronavirus SARS-CoV-2. The second study, presented on November 11 in the journal Nature Communications, says some children have developed an immune response following chronic exposure to their parents’ SARS-CoV-2 virus »Reports the site Why Doctor .

To achieve this result, the researchers studied blood samples from 302 children between the ages of one and sixteen. They then compared the results with those from samples from adult volunteers who did not contract the virus. ” The researchers believe that these results are important in the fight against the pandemic. “Our results show that children are much more likely to develop cross-reacting antibodies than adults,” continues Kevin Ng, author of the study. More research is needed to understand why, but it could be because children are more regularly exposed to other coronaviruses. ” This additional research must show, in particular, why adults who have been exposed to other coronaviruses during their life have not retained the antibodies that could protect them against Covid-19. Dr. Stephen J. Elledge, professor of genetics at Harvard School of Medicine, estimated at New York Times that these antibodies and the memory cells that accompany them disappear over time »Supports the specialized site. Explaining that the second study points out that the development of antibodies without being infected developed in young children of infected parents.
