ABSTRACT
We know little about the antigen bias in SARS-CoV-2 humoral response and the epitopes of spike recognized by the immune system in asymptomatic (AS) patients and symptomatic (S) patients. Here, we used a microarray to evaluate the humoral immune response in the sera collected from 33 COVID-19-recovered patients up to 1 year. We found that the levels of IgG and IgM induced by the 23 proteins differed significantly in the same patients, and were able to distinguish AS and S patients. The N- and S-specific antibodies were detected even at 12 months after onset. Five epitopes were identified to be associated with the clinical adverse events, and three peptides located in RBD. Overall, this study presents a systemic view of the SARS-CoV-2 specific IgG and IgM responses between AS and S recovered patients and provide insights to promote precise development of SARS-CoV-2 vaccines.
