There are few estimates of the seroprevalence of SARS-CoV-2 antibodies among children in the United States. We measured vaccine and infection induced seroprevalence among nearly 5000 healthy 1 to 17-year-old children in Colorado from 2020 to 2021. By December 2021, 89% of older children, ages 12 to 18, had antibodies detected. The increase was largely driven from vaccination rather than infection.
在美国，关于儿童感染 SARS-CoV-2 抗体的血清阳性率，目前仅有少数估计数据。我们在 2020 年至 2021 年期间，对科罗拉多州近 5000 名健康的 1 至 17 岁儿童进行了测量，发现疫苗和感染引起的血清阳性率。到 2021 年 12 月，89%的大龄儿童（12 至 18 岁）检测到抗体。这种增长主要是由疫苗接种驱动的，而不是感染。
