So. Much. Misinformation.
First of all, Ebola is nowhere near a kinship to HIV (I'm talking to you D3D). It does not simply attack the immune system, it alters cell-surface receptors and eventually fuses with the cellular membrane. It is able to overcome and rewrite the individual RNA of specific cellular structures to replicate. In essence, it turns your body into a feeding ground, eventually breaking down your individual cells and reorganizing them to become the virus. That's the most dumbed-down version I can give you.
Also, there are more than one type of vaccine. Prophylactic vaccines are created for immunization purposes. Therapeutic vaccines are created to assist in removing the mutated cells and controlling the spread of by giving the immune system a protein synthase to target. Cures can be created out of vaccines, but they are not the same. Also, the testing of a vaccine takes between 10 and 15 years, which includes the several years of laboratory research to simply find a "possible" antigen that "might assist" in the finding of a link between said antigen, and the vaccine. The first phase which includes animal AND human trials takes at least two years. Then on to phase II, which is where the PUBLIC can apply to be in the trial of the vaccine. This takes another several years. THEN there is ANOTHER trial that allows the application of tens of thousands of people globally. Another several years.
The only vaccine that is not under this scrutiny is influenza. The flu. That's the only vaccine that takes less time than this procedure. No, vaccines are NOT being researched, by the way, TREATMENTS are. No one is trying to stop Ebola, they're trying to help those who already have it and make it less lethal. That is almost ALWAYS the first step to vaccination anyway, treat the ones who have it, use them to find the antigen. It's basic virology.
