After more than two decades of waiting, the world has finally got a vaccine for the deadly Ebola Virus Disease (EVD).
The European Commission granted marketing authorization to Ervebo, the vaccine created by the pharmaceutical giant, Merck, last Monday. A day later, the World Health Organization (WHO) also announced its pre-qualification approval.
Ervebo also got a node from the European Medicines Agency last month.
