An experimental antiviral drug, Remdesivir, has protected monkeys against infection with Nipah virus, for which there is no approved vaccine or cure.

The same drug, Remdesivir, is also being tested against the Ebola virus in the outbreak now under way in the Democratic Republic of Congo.

What was the experiment?
In the new trial, eight African green monkeys were given lethal doses of Nipah virus. Half of them later got intravenous Remdesivir. All four monkeys that got the drug survived; the four that did not died within eight days.
