Kinetics of neutralization and VP1uAT ELISA responses to parvovirus B19 infections among children with SCD and TAC. Longitudinal serum samples from hospitalized patients were assayed. (A) Parvovirus B19 neutralization titers were defined as the inverse of the highest serum dilutions that reduced viral transcripts by 90%. (B) VP1uAT ELISA results. ND = antibodies not detected. Geometric means are shown with 95% confidence intervals. (C) VP1uAT and neutralization results on Day 30 are shown with Spearman’s correlation r and p values.
