There are new concerns about what was thought to be a promising vaccine against the deadly Ebola virus.



During the outbreak in West Africa, a new vaccine was developed by Merck and New Link Genetics.



A report in December said the vaccine was 100% effective.



But now, experts are questioning the way the study results were interpreted.
