Ebola vaccine trials could start in west Africa in December, with hundreds of thousands of doses potentially being rolled out by mid-2015, the World Health Organization said Friday.
"All is being put in place to start efficacy tests in the affected countries as early as December," said WHO assistant director general Marie-Paule Kieny, adding that several hundred thousand doses could be available in the "first half" of next year.
