Vaccine efficacy against SIV challenge. NHPs were challenged rectally with SIVmac239 and SIV RNA levels and CD4+ T counts were monitored. (a) Data show log of SIV RNA copies/ml of plasma of individual animals from vaccinated (top), and control (bottom) animals. (b) Percentages of CD4+ T lymphocytes in peripheral blood were analyzed from vaccinated (top), and control (bottom) animals. Gray filled lines represent means of each group. NHP, nonhuman primate; SIV, simian immunodeficiency virus.
