title: Does preserving memory correlate with surviving HIV?
abstract: The holy grail for HIV-1 vaccine researchers is to develop an efficacious vaccine, a goal that would be aided by defining a correlate of protection from infection. Recently, the authors of two papers have come one step closer to this goal with the definition of a correlate of survival following simian immunodeficiency virus (SIV) infection: the preservation of memory CD4(+) T cells during acute infection. Both of these research groups show that vaccination can prevent the initial immune devastation caused by SIV infection and that this correlates with survival following SIV challenge. Here, we highlight the significance of these two recent papers in light of the urgent need to produce an efficacious HIV vaccine and discuss several crucial issues that must be addressed before the correlate can be used in human clinical trials.
