Given the fact that mice immunized with DNA-TRYP(Pam3CSK4)+MVA-TRYP exhibit enhanced levels of memory T cells together with an overall reduction in IL-13 and increased IFNγ production in comparison to DNA-TRYP+MVA-TRYP or DNA-TRYP vaccinated mice, we asked whether these responses might be useful in directing protection against infection. Here, IFNG is linked to infection.
