An experimental vaccine tested on thousands of people in Guinea exposed to Ebola seems to work and might help shut down the ongoing epidemic in west Africa, according to interim results from a study.

There is currently no licensed treatment or vaccine for Ebola, which has so far killed more than 11,000 people in west Africa since the world's biggest outbreak began in the forest region of Guinea last year.

Scientists have struggled for years to develop Ebola treatments and vaccines, but have faced numerous hurdles, including the sporadic nature of outbreaks.

Researchers gave one dose of the new vaccine, developed by the Canadian government, to more than 4,000 people who were contacts of confirmed Ebola cases within 10 days of being identified.

In comparison, more than 3,500 contacts of other Ebola cases got the shot after a 10-day delay. In the group that received the vaccine immediately, there were no Ebola cases versus 16 cases in people who got delayed vaccination. The vaccine has since been licensed according to the Lancet journal.
