abstract：:An effective HIV vaccine will likely need to induce potent and broad-based immunity, including CD8+ T cell responses. Hence, a quantitative assay to measure such responses in animal models will be important in the evaluation of candidate HIV vaccines. We show here that a single immunization with HIV DNA vaccines, foll...
