In the published manuscript, Figures 3, 4, 6, and 7 were generated using slightly different parameter values than those quoted in the captions. Corrected versions of these figures are shown here. None of the conclusions of the study change as a result.

Other minor corrections:
The homeostatically dividing cell death rate μ is 0.77/day, not 1.06 as stated in the original caption to Figure 4. This rate is calculated using the constraint that approximately 1% of CD4+ T cells in blood are activated at the healthy set point, giving
In the third paragraph of the Results section, in the sentence beginning, “For the simulations we show below, we used the linear forms…”, the equation should read a(x) =a0 (1−x/κ).
At the end of the next paragraph, “given a and r” should read “given a(x) and r”.
In the caption of Figure 5, the third equation should read dw/dt = f a* x–(γ1 – γ2)w –pzw.
The authors are exceptionally grateful to Ben Bolker, Jess Beasley, and Carol Chaffee for bringing attention to these errors.
