从COVID-19中恢复与抗SARS-CoV-2抗体的产生有关,但尚不确定这些抗体是否赋予免疫力。我们描述了住院患者的病毒RNA脱落持续时间,并确定了复发性脱落的患者。我们对来自一名患者的两次不同的症状性COVID-19发作(相隔144天)的病毒进行了测序,以最终描述携带刺突变体D 614 G的不同菌株的再感染。该宗再感染个案是2020年报告的首批再感染个案之一。通过抗体、B细胞和T细胞分析,我们显示了再感染时获得性免疫的相关性,包括中和抗体对D 614 G假病毒的差异反应。最后,我们讨论了对疫苗计划的影响,并开始定义预防SARS-CoV-2再感染的基准。
Recovery from COVID-19 is associated with production of anti-SARS-CoV-2 antibodies, but it is uncertain whether these confer immunity. We describe viral RNA shedding duration in hospitalized patients and identify patients with recurrent shedding. We sequenced viruses from two distinct episodes of symptomatic COVID-19 separated by 144 days in a single patient, to conclusively describe reinfection with a different strain harboring the spike variant D614G. This case of reinfection was one of the first cases of reinfection reported in 2020. With antibody, B cell and T cell analytics, we show correlates of adaptive immunity at reinfection, including a differential response in neutralizing antibodies to a D614G pseudovirus. Finally, we discuss implications for vaccine programs and begin to define benchmarks for protection against reinfection from SARS-CoV-2.
