*The Spearman’s correlation analysis was performed using the baseline variables defined in the left column and the outputs of either the aggregate delta HAI (the sum of all three serotypes at the 2‐month time point minus the sum of the three serotypes at baseline) or the total aggregate HAI at the 2‐month time point. Significant associations are bolded.
