To understand how coronavirus disease 2019 vaccines impact infection risk in children <5 years, we assessed risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection from September 2022 to April 2023 in 3 cohort studies. There was no difference in risk by vaccination status. While vaccines reduce severe disease, they may not reduce SARS-CoV-2 infections in naïve young children.
为了解2019冠状病毒病疫苗如何影响5岁以下儿童的感染风险，我们在3项队列研究中评估了2022年9月至2023年4月期间严重急性呼吸综合征冠状病毒2（SARS-CoV-2）的感染风险。接种疫苗状况对感染风险没有影响。虽然疫苗可降低重症疾病的发生，但可能无法减少未接种疫苗的幼儿感染SARS-CoV-2。
