FIG 5 .

Neutralization response against maternal variants among infants that acquired infection and those that remained uninfected. (A and B) Area under the inhibition curve (AUC) values among AI versus HEU infants examined as (A) independent groups (Mann-Whitney test) and (B) matched pairs (linear regression model). Colors signify matched pairs for both analyses. (C) Correlation between infant AUC neutralization response against maternal strains and heterologous virus (BP score). The red and black dots indicate AI and HEU infants, respectively.
