Unfortunately, multiple strains complicate vaccine efforts. The closest thing to this virus they have experience with is SARS, and after 16 years they have been unable to produce an effective vaccine. The one they developed actually caused the test animals to die at a higher rate if vaccinated and then exposed to the actual virus. I don't know if its the same mechanism as how Dengue reinfections are more deadly than initial infections but the outcome was similar. There is a Dengue vaccine but it's not safe to get it unless you've already had Dengue.
