They are also working on Lassa fever, ebola, and marburg; three other bioterrorism threats of the hemorrhagic fever variety, fatal in 90% of people infected.

No word yet on the lassa fever one except that they got a $3.5 million dollar grant on April 10th,2013 from the US Army with USAMRIID scientists to study their vaccine. I think they go a perfect 3 for 3. We'll see though.
