These maps will allow mining of other correlations between peptide subpools, for example IFN-γ responses to Sp7 and Sp8 were highly correlated in the vaccinated with or without prior infection groups, but not in the uninfected and unvaccinated group (S3 Fig in S1 File), and further support the distinctness of the three groups as shown in Fig 4 and Tables 1–4. Here, IFNG is linked to infection.
