Abstract

Anti-COVID-19 immunity dynamics were assessed in patients with cancer in a prospective clinical trial. Waning of immunity was detected 4-6 months post-vaccination with significant increases in anti-spike IgG titers after booster dosing, and 56% of seronegative patients seroconverted post-booster vaccination. Prior anti-CD20/BTK inhibitor therapy was associated with reduced vaccine efficacy.

摘要

在一项前瞻性临床试验中,研究人员评估了癌症患者的抗 COVID-19 免疫动力学。接种疫苗后 4-6 个月,免疫逐渐减弱,但加强针后抗尖峰 IgG 滴度显著升高,56%的血清阴性患者在加强针后转为阳性。既往抗 CD20/BTK 抑制剂治疗与疫苗疗效降低有关。
