Fernández Villalobos, Marsall et al. analyzed seroprevalence and antibody responses to SARS-CoV-2 variants and endemic coronaviruses in Colombian children from urban and indigenous populations. They find high SARS-CoV-2 seroprevalence with comparable antibody titers but low neutralizing capacity and limited cross-protective immunity.
