A new experimental vaccine to treat the Marburg virus which has devastated Angola in recent months was 100 percent successful in tests on monkeys. This gives scientists increased hope that a human vaccine can be introduced that would prevent the spread of the deadly disease.

Researchers also tested monkeys with a vaccine against the Ebola virus, which is similar to Marburg. The findings were also promising.

The results of both studies were published in the journal 'Nature Medicine.' The Marburg virus affects both primates and humans. Thus far, 408 people have contracted the deadly Marburg virus and 340 of them have died. The disease is not yet fully under control according to local authorities and the World Health Organization.

This particular study used 12 macaques monkeys. Those macaques who were given the vaccine did not even get sick when they were later injected with high doses of the deadly virus according to the report.

Unfortunately, the vaccines will not even be ready to be tested on humans for another two years. While the vaccines may be too late to help the present crisis in Angola, they may offer hope for victims of the next major Marburg outbreak.
