"New Ebola Vaccine Gives 100 Percent Protection"

"In a scientific triumph that will change the way the world fights a terrifying killer, an experimental Ebola vaccine tested on humans in the waning days of the West African epidemic has been shown to provide 100 percent protection against the lethal disease.

The vaccine has not yet been approved by any regulatory authority, but it is considered so effective that an emergency stockpile of 300,000 doses has already been created for use should an outbreak flare up again.

Since Ebola was discovered in the former Zaire in 1976, there have been many efforts to create a vaccine. All began with a sense of urgency but then petered out for lack of money. Although only about 1,600 people died of Ebola over those years, the grotesque nature their deaths — copious hemorrhaging from every orifice — has lent the disease a frightening reputation."
