Four monkeys survived the Ebola virus after being injected with a vaccine that included Immunovaccine Inc.'s technology, the tiny Canadian company said on Monday, and the announcement sent its stock soaring.

The Halifax, Nova Scotia-based company said four monkeys received the vaccine and later survived a dose of Ebola virus that normally would have been lethal. Two other animals that did not receive the vaccine died within a week.

Immunovaccine, which had a market capitalization of about 77 million Cnadian dollars as of Friday, is one of a handful of companies involved in testing potential vaccines for the Ebola virus, which has killed nearly 1,500 people in West Africa.
