Ebola Vaccine Is the First to Block Infection

Since the outbreak of the most recent Ebola epidemic in West Africa, more than 11,000 people have died and more than 15,000 people have been infected with the virus. While some drug treatments have been marginally effective, no vaccine to protect against infection has yet been developed, although a number are currently being tested.

One of those, developed by the Public Health Agency of Canada and manufactured by [f500link]Merck[/f500link], showed early promise in 2015.
