a Representative images of P. vivax schizonts incubated with sera from an individual of the PvDBPII/M-M (0-1-14 months) group at dilution 1:5000. Sera at time point C-2 showed apical staining to PvDBP (green) in P. vivax schizonts compared to sera collected prior to initial immunization (D0). b Signal intensity in IFA for day C-2 and D0 sera from different groups tested at different dilutions. The fluorescence intensity of each sample was scored as: +++, for high intensity; ++, medium intensity; +, low intensity; and -, no signal. Some IFA samples that were not done are designated as ND.
