Childhood Humoral Immunity During and After COVID-19 Lockdowns
Résumé
Our study, including serum from 3678 hospital inpatients and outpatients sampled before, during and after the COVID-19 lockdown periods, showed a significant decrease in overall IgG levels during the periods of sanitary restriction, particularly in children 3–10 years of age. Few months after the lifting of COVID-19 restrictions, immunoglobulin levels normalized. COVID-19 lockdowns may have induced a transient humoral immune gap.
