Previous studies have suggested that a successful HIV vaccine will need to induce both broad humoral and cellular immune responses. Specifically, induction of class 1 MHC-restricted cytotoxic T lymphocytes and neutralizing antibody responses possibly against a number of viral antigens are important objectives in the design of second generation candidate AIDS vaccines. This is the first study in HIV-negative volunteers to evaluate safety, tolerance and immune response of APL 400-003 HIV DNA Vaccine using the Biojector 2000 system. The primary purpose of this project is to determine whether multiple intramuscular injections of the Genevax HIV (APL 400-003) DNA plasmid vaccine at dose levels of 100 ug and 300 ug can provoke an HIV-1 antigen- specific stimulation of the HIV negative immune system. Also, to determine if a multifaceted immune response characterized by production of HIV- specific antibodies, T helper cells and cytotoxic T lymphocytes; and which, under the appropriate conditions, may protect against infection by the Human Immunodeficiency Virus or delay the progression of disease.

先前的研究表明，成功的HIV疫苗需要诱导广泛的体液和细胞免疫反应。 具体而言，诱导1类MHC限制的细胞毒性T淋巴细胞和可能针对多种病毒抗原的中和抗体反应的诱导是第二代候选艾滋病疫苗的重要目标。这是使用Biojector 2000系统评估APL 400-003 HIV DNA疫苗的安全性，耐受性和免疫反应的HIV阴性志愿者的第一项研究。该项目的主要目的是确定对Genevax HIV（APL 400-003）DNA质粒疫苗的多次肌内注射是否以100 ug和300 ug的剂量水平会引起HIV-1抗原特异性刺激HIV HIV阴性免疫系统。 另外，确定多面免疫反应是否以HIV特异性抗体的产生为特征，T辅助细胞和细胞毒性T淋巴细胞；在适当的条件下，可以预防人类免疫缺陷病毒感染或延迟疾病的进展。
