Serological neutralization titers for EV71 and virus-specific plasmablast-derived mAbs from three children with laboratory-confirmed genotype B5 EV71 infection. a Paired sera were collected from donors and tested against a selection of clinical EV71 strains. b IgG plasmablasts collected on day 7 after illness onset were used to produce mAbs, and 34/68 antibodies from donor M, 25/69 antibodies from donor Y, and 25/54 antibodies from donor Z were specific to EV71. The neutralization assay was carried out twice with equivalent results
