There are two approved vaccines for Ebola Zaire, although availability is limited to those who work with it and those areas that are most affected. There is also a deficit in willingness to get vaccinated, as with many new vaccines.

There are several vaccines for Ebola Sudan in pre-clinical phases of development that are being fast-tracked in response to the current outbreaks. These are likely to be approved for emergency or compassionate use in the coming months, although general approval may be years away.

There are many factors that may influence a vaccine's availability, namely in resource-limited areas. Cost is just one of them. Developing effective disease treatment requires funding as well as support through technological and scientific resources that can be limited by your geographic area, infrastructure, and more.
