Ebola trials begin as fresh cases confirmed

Two new ebola vaccine trials began with volunteers in Britain, France and Senegal getting “prime-boost” immunisations developed by Bavarian Nordic, GlaxoSmithKline and Johnson & Johnson.

The mid-stage, or Phase II, trials are designed primarily to test the vaccines’ safety, but will also assess whether they provoke an immune response against the deadly virus.

The development of the prime-boost and other vaccines was accelerated in response to vast outbreaks of ebola in West Africa, where at least 11,200 people have died so far in Guinea, Sierra Leone and Liberia.
