Vaccine developed against Ebola
Scientists have developed a vaccine that protects mice against a deadly form of the Ebola virus.
The researchers say that this is the first Ebola vaccine to remain viable long-term and can therefore be successfully stockpiled.
The vaccine protects 80% of the mice injected with the deadly strain, and survives being "dried down and frozen," said biotechnologist Charles Arntzen from Arizona State University who was involved in its development.
He said the next step is to try the vaccine on a strain of Ebola that is closer to the one that infects humans.
