Participants, including health officials, vaccine manufacturers and government representatives from the hardest-hit countries will also review available financing to bring promising candidate vaccines to the market.

They will also look at ways to ensure the broadest possible access once a safe and efficient vaccine is found.

A third promising candidate, the VSV-ZEBOV, manufactured by the Public Health Agency of Canada and licensed by US firm NewLink Genetics, is also being tested in the United States, Canada, Germany and Gabon.

Tests of VSV-ZEBOV on volunteers in Switzerland were meanwhile briefly suspended late last year over concerns over unexpected side-effects, but resumed this week after the doses being injected were reduced.
