LONDON  - Scientists are to test a new two-shot Ebola vaccine using an experimental shot from Britain's GlaxoSmithKline, which is already in clinical trials in Africa, and a new kind of booster from Emergent BioSolutions.

The Maryland-based biotech company said on Monday its modified vaccinia Ankara (MVA) Ebola Zaire vaccine would be used in an initial Phase I clinical study to be conducted by researchers at the University of Oxford.

Although Ebola case numbers have fallen to a low level, drug companies are still pushing ahead with efforts to develop an effective vaccine, which may help fight the next outbreak, even if it does not come in time for the current epidemic.

The National Institutes of Health (NIH) may relocate its clinical trials of Ebola vaccines to Guinea, since there are no longer enough Ebola cases in Liberia for a proper efficacy trial.

On Feb. 2, the NIH launched an initial safety trial for two vaccines to protect against Ebola in Liberia. The plan was to test 600 people for overall safety and then launch a second phase of the trial in 27,000 people to see whether or not the vaccine prevents infection with Ebola virus compared to a placebo.

The safety test was successfully completed the week of March 9—but around the same time, Liberia announced that it had released its last confirmed patient from its Ebola treatment centers. ...
