A protocol to evaluate antigen-specific T-cell responses in the immunoprivileged organs of the Ifnar1^-/- murine model for the Zika virus (ZIKV) infection is described. This method is pivotal for investigating the cellular mechanisms of the protection and immunopathogenesis of ZIKV vaccines and is also valuable for their efficacy evaluation.

In this study, an infectious clone of human adenovirus type 7 (HAdV-7) was constructed, and an E3-deleted HAdV-7 vector system was established by modifying the infectious clone. This strategy used here can be generalized to make gene transfer vectors from other wild-type adenoviruses.
