claim: iga dominates the early neutralizing antibody response to sars-cov-2
evidence_1: our results show that human iga antibodies are often detectable before the appearance of sars-cov-2-specific igg and suggest a role for iga antibodies in early virus neutralization.", "our results show that serum iga, particularly anti-rbd iga, are detected earlier compared with igg, and the dramatic plasmablast expansion that follows sars-cov-2 infection is dominated by iga-secreting cells (fig.", "early sars- cov-2-specific humoral responses were dominated by iga antibodies.")
