We investigated the kinetics of severe acute respiratory syndrome coronavirus 2 neutralizing antibodies in 7 asymptomatic persons and 11 patients with pneumonia. The geometric mean titer of neutralizing antibodies declined from 219.4 at 2 months to 143.7 at 5 months after infection, indicating a waning antibody response.
我们研究了 7 名无症状感染者和 11 名肺炎患者体内严重急性呼吸综合征冠状病毒 2 中和抗体的动力学。中和抗体的几何平均滴度从感染后 2 个月的 219.4 下降到 5 个月时的 143.7,表明抗体反应逐渐减弱。
