WHO: Millions of Ebola vaccine doses coming by the end of 2015

Two experimental vaccines, produced by GlaxoSmithKline (GSK) and the Public Health Agency of Canada, are already in safety trials.

The GSK vaccine is being tested in Mali, the UK and the US. Research on the Canadian vaccine is also under way in the US with further trials expected to start in Europe and Africa soon.

The results are expected in December. After that, trials will move to countries affected by Ebola, probably starting with Liberia.
