Figure 3.

The γHV-68-specific CD8⁺ T cell responses following secondary challenge of persistently infected I-A^b−/− mice. The mice were infected with γHV-68, then challenged with the vacc-p56, vaccp79, and vacc-LCMV^b recombinants, as described in the Fig. 1 legend. The results are given as mean ± SE for virus-specific CD8⁺ T cells in the spleens of three mice. Those sampled on day 63 after vaccinia (day 91 after γHV-68) were clinically affected and provide some of the virus titer results presented in Table 2.
