From this article:
“If the vaccine appears effective and safe in a number of animal species, it will go into clinical trials on humans. This takes at least one year even if expedited,” Yuen said.
Inovio of San Diego already have a computer designed but untested DNA vaccine. In the past DNA vaccines have not been approved for use in humans but they are partnered with a Chinese company and I'm not sure the Chinese will be as conservative as the FDA in terms of trying things.

Their previous Elboa vaccine seemed to work well in tests though I think it never made it to the field. http://ir.inovio.com/news-and-media/news/press-release-detai...
I sometime think the testing protocols are a bit over cautious when you have a candidate that is probably safe and quite likely effective.
