The World Health Organisation has suggested that millions of doses of two experimental Ebola vaccines could be ready for use in 2015 and five more experimental vaccines would start being tested in March.
Trials of those two most advanced vaccines have already begun in the US, UK and Mali.
If the early vaccine trials hint at success, larger trials testing the vaccines in West Africa could begin as soon as December.
Dr. Marie-Paule Kieny is the World Health Organisation Assistant Director-General.
"If, still, the massive effort and response is not sufficient to bring the epidemic under control, then a vaccine would be a very important tool."
She admitted that plans were changing "week to week" as governments, health agencies and donor countries tried to speed up efforts to fight the deadly virus.
The European Union and its 28 member nations have managed to come up with 1 billion euros to fight the Ebola crisis.
Kieny also confirmed the report of the first case of Ebola in Mali, a two-year-old girl who came to the country from Guinea.
