Global: Vaccine hope for deadly disease

Scientists are hopeful a vaccine against the deadly tropical disease Marburg virus could be developed. Similar to the Ebola virus, Marburg causes internal bleeding leading to multiple organ failure in 90% of cases - there is no effective treatment. A US-Canadian team writing in the Lancet say they have created a jab which appears to protect monkeys from Marburg's harmful effects. Both the Marburg and Ebola viruses are considered potential bio-terror agents.
