A recent report by Davis et al. shows that following vaccination, B‐cell activation results in the emergence of a population of antibody‐secreting cells (plasmablasts – PBs) in blood and a population of plasma cells (PCs) in the bone marrow, which likely originate from the day 7 PBs. However, these newly arrived PCs do not become long‐lived and their abundance decreases by 1 year post‐vaccination.

流感疫苗接种后骨髓浆细胞的升降

戴维斯等人最近的一份报告。表明接种疫苗后，B 细胞活化导致血液中出现抗体分泌细胞群（浆母细胞 - PB）和骨髓中出现浆细胞（PC）群，这可能起源于第 7 天 PB . 然而，这些新到达的 PC 不会变得长寿，并且在接种疫苗后 1 年它们的丰度会下降。
