Eight experimental treatments and two vaccines for Ebola were on the table Thursday as 200 health experts met in Geneva Thursday to discuss how to end the world's worst-ever outbreak of the killer virus.But "while extraordinary measures are now in place to accelerate the pace of clinical trials, new treatments or vaccines are not expected for widespread use before the end of 2014," the World Health Organization stressed in a working document.
