The most recent Ebola outbreak did however, prompt researchers to accelerate the pace of developing an effective vaccine against the deadly virus – and if we are to believe fresh reports from major publications around the world, we might be just one step away from having an effective Ebola vaccine in place. Reporting Thursday in the medical journal Lancet, the study team found that not a single individual among thousands who received the vaccination as soon as they were identified as being at risk of exposure ended up infected with Ebola. "While these compelling results come too late for those who lost their lives during West Africa's Ebola epidemic, they show that when the next Ebola outbreak hits, we will not be defenceless," said Marie-Paule Kieny, WHO's Assistant Director-General for Health Systems and Innovation, and the study's lead author. According to the journal, a clinical trial conducted on more than 12,000 people – mostly from countries like Guinea and Sierra Leone, among the worst affected by the outbreak back in 2013-14 indicated that the vaccine was proving to be very effective. John-Arne Røttingen, director of the division of infectious disease control at the Norwegian Institute of Public Health, who worked on the study said;

The new Ebola virus vaccine was discovered by the Public Health Agency of Canada. Reports state that although the vaccine has not yet been approved by any regulatory authority, it is considered so effective that the researchers have already created an emergency stockpile of around 300,000 doses of it to use in any future flare-up of the disease which killed thousands of people in West Africa. Initial tests last year did not include children, while the most recent trials covered those over six years old.
A vaccine for the ebola virus is discovered to be 99.78%–99.87% effective.
