The first trials in Africa of a potential Ebola vaccine have started on health workers in Mali. Mali currently has no Ebola cases but it borders Guinea, where the outbreak began. The trials are hoping to determine whether the potential vaccine is safe and whether it increase immunity against Ebola.
Safety trials of this vaccine began a few weeks ago at the Jenner Institute. The healthy people who have volunteered so far have shown no ill effect, so the trials have now moved in to Africa as well.
