Compared to the pre-variants period of the epidemic,chil-dren currently account for a higher proportion of COVID-19 cases and a higher hospitalization rate.Considering that var-iants of concern show increased transmissibility,children,being the largest unvaccinated population,may be more likely to transmit and result in more COVID-19 cases in the future.Vaccination has benefits in terms of reduced com-munity transmission and will help achieve herd immunity,which could considerably reduce morbidity,mortality,and pressure on health systems.It is also possible that it will help protect them from new variants.Furthermore,the available evidence confirms that the COVID-19 vaccines are safe and effective for children.Taking all these considerations into account,we should promote the vaccination against COVID-19 in children.
