Viral loads are reported as copies/ml. Vax: Value at time of vaccination, A: Asian, B: Black, H: Hispanic, W: White. Data are mean ± standard error of the mean. * indicates
significant difference (p<0.05) compared to the CD4<200, HAART group. # indicates significant differences (p<0.05) compared to the CD4<200 group. |
