Ebola vaccine tests needlessly delayed???

As we know the number of Ebola cases is now almost doubling every 3 weeks. Why Ebola vaccine tests needlessly delayed???

Typically, vaccine development can take many many years. A tetravalent dengue vaccine , for example, has taken 6-8 years at least to get to phase three trials after having disappointing results during phase two. Dengue continues to causes a lot of illness and and some mortality , especially in South East Asia.

We still do not have a malaria vaccine available but there are over 200 million cases of malaria every year and over half a million deaths.

For Ebola, trials for two most promising vaccine candidates have been accelerated to the point where some ethicists feel it could cross the line. Opinion differs on this.

What level of efficacy is good enough and what amount of side effects are safe enough for an Ebola vaccine ?

Should we have different standards for an ebola vaccine vs ones for malaria and dengue?
