Current guidelines recommend a combined schedule of a 13-valent pneumococcal conjugate vaccine (PCV13) and PPSV23 (23-valent polysaccharide vaccine) for asplenic individuals. We show that PCV13 induces a T-dependent immune response in asplenic individuals with β-thalassemia, but previous PPSV23s affect the memory B-cell response in a dose- and time-dependent manner. Clinical Trials Registration. NCT01846923.
现行指南建议对脾切除个体同时使用 13 价肺炎球菌结合疫苗（PCV13）和 PPSV23（23 价多糖疫苗）。我们发现 PCV13 可诱导β-地中海贫血脾切除个体产生 T 细胞依赖性免疫应答，但既往 PPSV23 会以剂量和时间依赖的方式影响记忆 B 细胞应答。临床试验注册。NCT01846923。
