However, there was no difference (p = 0.71) in IFNγ ELISpot responses to non-dengue FEC peptides in those with SS responses (mean 397.5 SFU/million PBMCs) when compared to those who did not have SS responses (mean 239.3 SFU/million PBMCs) (Fig. 1B). This evidence concerns the gene IFNG and dengue disease.
