While West Africa is on its way to be nearly Ebola-free, Dr Marie-Paule Kieny, assistant director-general for Health Systems and Innovation with the World Health Organization says that 2 experimental Ebola vaccines being tested on volunteers may not yield sufficient data on efficacy.
With Ebola nearly stamped out in West Africa, vaccine trials will probably fail to provide enough useful data on how well they protect people against the deadly virus, the World Health Organization (WHO) said on Tuesday.
Liberia was declared free from Ebola by the government and the WHO on Saturday after 42 days without a new case of the virus, which killed more than 4700 people there during a year-long epidemic.
Guinea reported 7 cases in the week of May 4-10, while Sierra Leone had two, Dr. Marie-Paule Kieny, WHO Assistant Director-General for Health Systems and Innovation, told a news briefing in Geneva.
