ERE vaccine-induced T cells do not expand <i>in vivo</i> following SIVsmE660 infection.

<p>Vaccine induced T cell responses detected in ELISPOT above the threshold of 50 IFN-γ spot forming cells (SFCs) at two weeks prior to SIV infection were tracked for the first six weeks post infection and are shown for animals [<b>A</b>] r07015, [<b>B</b>] r99047, and [<b>C</b>] r99080 from vaccine group one and [<b>D</b>] rh1999, [<b>E</b>] r05040, and [<b>F</b>] r99079 from vaccine group two. Similar results were obtained for the remaining animals in both groups. The results shown indicate the mean plus standard deviation of duplicate wells for the indicated peptide pools with the background level subtracted. Time from last ERE vaccination [Ad5 for group 1, DNA for group 2] is indicated at the top of each graph.
