World Health Organization says it hopes to deploy the experimental Ebola vaccine to tackle an outbreak in a remote area of the Congo Democratic Republic to prevent it spreading, particularly to the provincial capital which has over 1 million people.
Two of the neighboring countries - the Central African Republic (CAR) and the Republic of Congo - have "a slightly higher level of risk" due to their river-based links to DRC, Salama said.
It can be used to protect people who have had contact with Ebola victims, stopping the spread of disease, but that requires intensive contact tracing, which Salama said could take a week or two just for the cases already documented.
The West African outbreak lasted for three years, infected about 28,000 people, killed 11,000 and spread out of Africa to places like the U.S. and Europe. The researchers found that there were no Ebola cases among the 5,837 vaccinated people 10 days or more after getting vaccinated.
In a press conference given in Geneva on Friday, Peter Salama, head of the WHO's emergency response, told reporters the worldwide health organization is taking the newest outbreak of this Ebola virus very seriously.
The ministry said clinics and hospitals across the East African country have been provided with necessary equipment to treat suspected Ebola cases, and training is being provided to strengthen response capabilities.
Salama also said the United Nations health organisation hoped to have a mobile lab up and running on site this weekend.
Deputy Director-General of Emergency Preparedness and Response Peter Salama said the organisation was "preparing for the worst-case scenario".More news: David Goodall: Scientist, 104, ends his life in Switzerland
Nigeria has already stepped up screening processes at this entry points including major worldwide airports in the country to ensure no outbreak is recorded.
A team from World Health Organization and its partners is already on the ground, personal protective equipment has already been deployed, and a surge team of 20 to 40 World Health Organization outbreak specialists is set to arrive.
So far, no case of Ebola has been reported in Angola.
The outbreak, declared by the DRC health ministry on Tuesday, is the DRC's ninth known outbreak of Ebola since 1976, when the deady viral disease was first identified in then-Zaire by a Belgian-led team.
He told a United Nations briefing in Geneva that he hoped the Democratic Republic of Congo would deploy an "experimental vaccine".
In addition to the Democratic Republic of the Congo, past Ebola outbreaks have occurred in Gabon, South Sudan, Ivory Coast, Uganda, Republic of Congo and South Africa.
