Progress, Partnership and Perseverance. The annual AIDS Vaccine conference is the largest and most diverse international meeting of researchers, advocates, clinicians, private sector partners and public health experts working collaboratively to advance HIV vaccine science. HIV vaccine research has progressed further and faster in the last few years than at any time since the epidemic began. AIDS Vaccine 2013 will focus on partnerships and perseverance to transform these advances into a safe and effective vaccine to help end the pandemic.

From the title of this, it looks like it is a basic science poster. Production of granzyme B is induced in activated natural killer (NK) cells and CD8+ cytotoxic T cells as a means to kill virally infected cells. It doesn't say whether this is in HIV infected or non-infected individuals. They will probably show that cytotoxic T cells from vaccinated patients have up-regulation of granzyme. I don't think this will be the big splash that we are all anticipating, unless they present some clinical data from the HIV-infected patients.
