One shot of an experimental Ebola vaccine can trigger fast protection, according to new monkey studies. However, the effect waned unless the animals got a booster shot made in a different way. 

Some healthy people are volunteering for the first human safety study of these vaccines, hoping that it eventually might be used in the current Ebola outbreak in West Africa. 

Some of the key animal research behind those injections were published recently by the National Institutes of Health. 

One reason the vaccine was deemed promising was that a single dose protected all four vaccinated monkeys when they were exposed to high levels of Ebola virus just five weeks later, the press release added. 

With the Ebola crisis rapidly worsening, the World Health Organization said Friday that it would try to speed the use of certain experimental products, including two vaccine candidates. WHO added that in November, it expects early results from first-stage studies to see if the vaccine appears safe and triggers immune reaction in people.

Researchers reported their findings in the journal Nature Medicine.
