Abstract

Children often show milder COVID-19 symptoms, but the underlying mechanistic insights are still lacking. Here the authors profile both pediatric and adult cohorts of COVID-19 patients in Brazil to find that children exhibit higher viral load but stronger and biased cellular immunity, thereby serving clues for the differential responses in children.
