Health workers in Uganda have received clearance to start using experimental vaccines for the Ebola disease.
Last week two people who had travelled from the neighboring Democratic Republic of Congo, DRC, died from Ebola in Uganda.
People who came into contact with them have already received experimental vaccines.
The head of the World Health Organisation, Tedros Adhanom has been visiting Uganda and Congo, DRC.
The outbreak in Congo is the second worst on record, with more than 1,400 people dying of the disease.
