(1)Technology has improved since 2014. (2)Not only is there a quicker diagnostic test, but there are also ample supplies of an effective vaccine. (3)Thousands of doses are being deployed in a “ring” strategy, to inoculate those who have been in contact with known cases of Ebola, as well as their contacts in turn. (4)Jabs are also being offered to front-line health workers—an essential precaution, given the large number of such workers who died last time. (5)It is not yet clear how well ring vaccination will contain the early stages of an outbreak, when chains of transmission are less certain. (6)The vaccine is also hard to administer, since it must be kept as low as -80°C. (7)However, if this one proves unsuitable, another is available that might work.
