Serum IgA antibodies against vaccine GI.4 and GII.4 VLPs
The magnitude and kinetics of the IgA response against the vaccine antigens, GI.4 Chiba 407 (1987) and GII.4 Aomori 2 (2006) VLPs, are shown in Antibody response to vaccine antigens expressed as Geometric Mean Titer (EU/ml) of anti-GI.4 and anti-GII.4 VLP IgA at scheduled time points for each study group.CI, confidence interval; Geomean, geometric mean antibody concentration.*Geometric mean values are expressed as EU/ml (ELISA units per milliliter).Anti-GI.4 and anti-GII.4 VLP serum IgA responses. Anti-GI.4 and anti-GII.4 VLP IgA responses by scheduled time for each treatment. Vaccine or placebo were administered on days 1 and 29. OD values were processed using a 4-parameter logistic fitting algorithm to the standard curve, allowing the determination of antibody concentration in the samples, expressed as EU/ml. Anti-GI.4
