This is weird news stuff. I doubt Ebola will ever be that bad. If you look at the people in countries like South Africa, notice how they are very unclean and dangerous places to be. Even if someone in America got Ebola, the chances of living are even greater due to the care given throughout a lifetime of good health and not to mention hospitals.
A vaccine shot would be a waste of money in my opinion. Just until Ebola turns into zombies of course.
