Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 and has caused a pandemic of acute respiratory disease, known as ＂coronavirus disease 2019＂ (COVID-19). Children and adolescents account for 15% of all COVID-19 cases globally. Although the majority of pediatric patients have mild to moderate illness, they are still responsible for transmission. School closure and vaccination are the two main methods of infection control. However, the optimal means of striking a balance between the advantages and disadvantages of these methods remains unsolved.
