Cited in Scopus: 3In this study, we analyzed the clinical efficacy of mRNA-based COVID-19 vaccines among Italian children aged 5 to 11 years, using data published by the National Institute of Health. Vaccination status was associated with a reduced risk of COVID-19–related hospitalizations and intensive care unit (ICU) admissions, which were 41% (odds ratio, 0.59; 95% confidence interval [CI], 0.46-0.77) and 68% (odds ratio, 0.32; 95% CI, 0.04-2.63), respectively, lower in children who completed the vaccination cycle <120 days than in the unvaccinated matched population.
