According to the BBC, health workers in the Democratic Republic of Congo (DRC) will shortly begin an immunisation campaign to control the Ebola outbreak.
An experimental vaccine that is not yet licensed but was found to be effective in trials during the outbreak in West Africa in 2014-16 will be used, and health workers will be among the first to be vaccinated.
The first batch of over 4,000 doses has arrived in Mbandaka but needs to be stored at between -60 and -80°C, which could present a challenge as electricity supplies are unreliable in the area.
The World Health Organization (WHO) has identified around 500 people who may have come into contact with Ebola patients in the DRC who will be included in the immunisation campaign.
