Canada says it will donate up to 1,000 doses of an experimental Ebola vaccine¹ to help battle the disease's outbreak in West Africa.

加拿大政府将捐赠1000支埃博拉实验疫苗帮助西非对抗该病毒。

It comes after the World Health Organization said it was ethical² to use untested drugs on Ebola patients.

However, experts say supplies of both the vaccine and the experimental drug Zmapp are limited and it could take months to develop more supplies.

More than 1,000 people have been killed by the current outbreak.

Canada says between 800 and 1,000 doses of the vaccine, which has only been tested on animals, will be donated to the World Health Organization (WHO) for use in West Africa.

However, it will keep a small portion of the vaccine for research, and in case it is needed in Canada.

'Global resource'

The current outbreak has infected people in Guinea, Sierra Leone, Liberia and Nigeria.

Dr Gregory Taylor, deputy head of Canada's Public Health Agency, said he saw the vaccines³ as a "global resource".

He said he had been advised that it would make sense for health care workers to be given the vaccine, given their increased risk of contracting the disease.
