At present, there is no relevant research focusing on children's acquisition of novel coronavirus antibodies through maternal passive transmission. Therefore, this study assessed the changes of maternal passive transmission of COVID-19 antibodies by monitoring the specific antibodies of COVID-19 in young children; This will lay a foundation for further exploring the risk of COVID-19 infection in children and formulating immune prevention strategies.
