cTfh responses to primary ETEC vaccination correlated with vaccine specific memory IgA ALS responses. Correlation between the cTfh response magnitudes (fold rises in ICOS expression above baseline prevaccination levels) in the primary vaccination study and the combined response index of memory vaccine specific IgA ALS responses against the five major vaccine antigens elicited by booster vaccination. Each symbol represents one individual (n = 11) and data is displayed in a log-log scale plot.
