INNATE IMMUNE SYSTEM RESPONSE: Rapid immune response in children protects them from COVID-19, genetic study finds. “The study, published in Nature, is the most comprehensive single-cell study to compare SARS-CoV-2 infection in adults and children across multiple organs. Researchers found that a stronger ‘innate’ immune response in the airways of children, characterized by the rapid deployment of interferons, helped to restrict viral replication early on. In adults, a less rapid immune response meant the virus was better able to invade other parts of the body where the infection was harder to control.”
