感染诱导的 SARS-CoV-2 免疫力的持久性对于再感染和疫苗开发具有重大影响。在这里,我们展示了一组从轻度至中度 COVID-19 中康复的患者随时间变化的抗体、B 细胞和 T 细胞动态的全面概况。结合和中和抗体反应以及个体血清克隆型在感染后的前 4 个月内衰减。 Spike 特异性 CD4+ 和循环 T 滤泡辅助频率也会出现类似的下降。相比之下,S 特异性 IgG+ 记忆 B 细胞随着时间的推移不断积累,最终构成循环记忆 B 细胞库的很大一部分。伴随的免疫动力学模型预测,50% 的恢复期参与者在 74 天内将血清学中和活性维持在 1:40 以上的滴度,尽管可能存在针对 B 细胞和 T 细胞免疫的额外保护。这项研究表明,感染 SARS-CoV-2 后的免疫力可能在人群水平上具有短暂的保护作用。因此,SARS-CoV-2 疫苗可能需要比自然感染更强的免疫原性和持久性,才能实现长期保护。需要纵向分析来显示对 Sars-Cov-2 感染的免疫反应如何随时间变化。在这里,作者使用多种策略来分析 COVID-19 恢复期患者在约 5 个月的过程中免疫细胞反应的变化,结果表明,尽管中和抗体反应在约 4 个月后下降,但 B 细胞免疫反应增强。
The durability of infection-induced SARS-CoV-2 immunity has major implications for reinfection and vaccine development. Here, we show a comprehensive profile of antibody, B cell and T cell dynamics over time in a cohort of patients who have recovered from mild-moderate COVID-19. Binding and neutralising antibody responses, together with individual serum clonotypes, decay over the first 4 months post-infection. A similar decline in Spike-specific CD4+ and circulating T follicular helper frequencies occurs. By contrast, S-specific IgG+ memory B cells consistently accumulate over time, eventually comprising a substantial fraction of circulating the memory B cell pool. Modelling of the concomitant immune kinetics predicts maintenance of serological neutralising activity above a titre of 1:40 in 50% of convalescent participants to 74 days, although there is probably additive protection from B cell and T cell immunity. This study indicates that SARS-CoV-2 immunity after infection might be transiently protective at a population level. Therefore, SARS-CoV-2 vaccines might require greater immunogenicity and durability than natural infection to drive long-term protection. Longitudinal analyses are needed to show how the immune response to Sars-Cov-2 infection changes over time. Here, the authors use multiple strategies to profile the change in immune cell responses from patients with convalescent COVID-19 over the course of ~5 months, showing that although neutralizing antibody responses drop off after ~4 months, B cell immune responses strengthen.
