Hematological malignancies are associated with an increased risk of complications during SARS-CoV-2 infections. Primary series or monovalent booster vaccines reduce disease severity, hospitalization, and death among multiple myeloma patients. We characterized virus-neutralizing and spike-binding antibody profiles following monovalent (WA1) or bivalent (WA1/BA.5) SARS-CoV-2 booster vaccination in MM patients. Bivalent vaccination improved the breadth of binding antibodies but not neutralization activity against contemporary variants. Hybrid immunity and immune imprinting impact vaccine-elicited immunity.
血液系统恶性肿瘤与感染严重急性呼吸综合征冠状病毒2（SARS-CoV-2）期间并发症风险增加相关。单价或二价加强疫苗可降低多发性骨髓瘤患者的疾病严重程度、住院率和死亡率。我们对多发性骨髓瘤（MM）患者接种单价（WA1）或二价（WA1/BA.5）SARS-CoV-2加强疫苗后的病毒中和及刺突结合抗体谱进行了特征分析。二价疫苗接种改善了结合抗体的广度，但对当代变体的中和活性没有改善。混合免疫和免疫印记会影响疫苗诱导的免疫。
