Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

While antiretroviral drugs have shown great promise in reducing HIV replication and thus in reducing HIV/AIDS associated morbi-mortality and HIV transmission, the cost is substantial and side effects are a potentially limiting factor. Development of an effective safe-affordable vaccine is likely to be the best way to stop further virus spread. The study aims to determine safety and immunogenicity of the DNA-vaccine at a dose of 600µg and 1200µg delivered id in combination with MVA-CMDR boost im.
