FIG. 3.

Predominantly high-avidity P-specific response in mice immunized with SV5. BALB/c mice were immunized i.n. with 3 × 10⁶ PFU of SV5, and ELISPOT assays were performed 6 days (A), 12 days (B), 18 days (C), or 40 days (D) after infection as described in the legend to Fig. 2. ELISPOT assays were performed in the absence (cross-hatched bars) or presence (black bars) of anti-CD8 blocking antibody. The data shown are representative of three independent experiments.
