摘要
Dear Editor,The coronavirus disease 2019(COVID-19),caused by the Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2),is an ongoing threat to public health.Due to the presence of neutralizing antibodies in convalescent patients,convalescent plasma transfusion has been tested as a promising therapy for severe COVID-19 patients.12 We and others previously found a surprisingly early serum lgA antibody response in the COVID-19 patients.However,the relative contribution of the lgA antibody towards virus neutralization with respect to other antibody isotypes is unknown.
