Human trial for Ebola vaccine to begin:
The first human trial for an investigational Ebola vaccine is set to begin this week.
The ongoing Ebola outbreak in West Africa prompted the National Institutes of Health to expedite safety testing for several vaccines already in the works. Since March, the deadly virus has killed 1,552 people, according to the World Health Organization, which predicted last week that the virus could infect 20,000 people in the next six months.
An Ebola vaccine is different from the experimental Ebola drug ZMapp, which two Americans received last month and is designed to treat an existing Ebola infection rather than prevent one.
“There is an urgent need for a protective Ebola vaccine, and it is important to establish that a vaccine is safe and spurs the immune system to react in a way necessary to protect against infection,” Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health, said in a statement.
