FIG. 2.

ICS data for virus-specific CD8⁺-lymphocyte responses in animals vaccinated with DNA/MVA. The frequency of responding CD8⁺ cells against each protein is shown. These frequencies were obtained by adding the frequencies detected with peptide pools containing overlapping peptides from a single protein (after subtraction of the background). CD8⁺ responses after the first MVA boost (prior to infection), 2 weeks postinfection (acute phase of infection), and 12 weeks postinfection (chronic phase of infection) are shown.
