CD8A and infection: To better understand the immunological correlates of protection by MVA-EBOV-NP vaccination (Figure 2C), mice were vaccinated as described before with MVA-EBOV-NP and the CD8+ T cells were depleted at days −2, 0, 2 and 4 pre- and post-infection by intraperitoneal administration of a monoclonal antibody directed against CD8+ T cells [50].
