Extended Data Fig. 4: Baseline RSV-specific NAb and antibody levels by infant age.

a, GMC of NAb. b, GMC of pre-F. c, GMC of post-F. d, GMC of Ga. e, GMC of Gb. f, GMC of N. The box is bounded by the 25th and 75th percentiles; the line within the box represents the median. The whiskers represent 1.5 x IQR. AU ml-1, arbitrary units per milliliter; CI, confidence interval; F, fusion protein; Ga, attachment protein G RSV subtype A; Gb, attachment protein G subtype B; GMC, geometric mean concentration; IgG, immunoglobulin G; IU ml-1, International Units per milliliter; IQR, interquartile range; LLOQ, lower limit of quantification; n, number of infants; N, nucleocapsid N; NAb, neutralizing antibodies; RSV, respiratory syncytial virus.
