The latest progress of the Ebola vaccines? (Score 1)

I learned from a blog entitled Vaccines and Therapies Targeting Ebola Virus May Meet Breakthroughs that the United States National Institutes of Health and the Food and Drug Administration are collaborating to speed up the clinical trials of vaccines. They announced that, in this September, an Ebola vaccine would be ready for clinical trials. Does anybody know the latest news about this vaccine?
