摘要

Abstract

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) is a newly identified member of the coronavirus family that has caused the coronavirus disease 2019 (COVID-19) pandemic. This rapidly evolving and unrelenting SARS-CoV-2 has disrupted the lives and livelihoods of millions worldwide. As of 23 August 2021

a total of 211

373

303 COVID-19 cases have been confirmed globally with a death toll of 4

424

341. A strong understanding of the infection pathway of SARS-CoV-2

and how our immune system responds to the virus is highly pertinent for guiding the development and improvement of effective treatments. In this review

we discuss the current understanding of neutralising antibodies (NAbs) and their implications in clinical practice. The aspects include the pathophysiology of the immune response

particularly humoral adaptive immunity and the roles of NAbs from B cells in infection clearance. We summarise the onset and persistence of IgA

IgM and IgG antibodies

and we explore their roles in neutralising SARS-CoV-2

their persistence in convalescent individuals

and in reinfection. Furthermore

we also review the applications of neutralising antibodies in the clinical setting—from predictors of disease severity to serological testing to vaccinations

and finally in therapeutics such as convalescent plasma infusion.
