Mattias Schnell, a Jefferson microbiologist, is working on the "no vaccine" problem, but says his solution, a new vaccine, will not come fast enough for this outbreak. It might be ready for the next one. He is working on a combined rabies/Ebola vaccine with the National Institutes of Health. The rabies vaccine - rabies is a big problem in Africa - is already in use. He hopes to begin a Phase I clinical trial within eight to 12 months.
