One of the world’s deadliest diseases, caused by the Ebola virus, may finally be preventable thanks to US and Canadian researchers, who have successfully tested several Ebola vaccines in primates and are now looking to adapt them for human use.

The deadly Ebola virus, an emerging public health concern in Africa and a potential biological weapon, ranks among the most feared of exotic pathogens.

A topical respiratory tract vaccine tested for the first time in a primate model may protect against Ebola virus infection. Researchers from the National Institutes of Health, Bethesda, MD and the Centers for Disease Control, Atlanta, GA report their findings in the June 2007 issue of the Journal of Virology.
