Work is going on furiously at private and government laboratories to find a vaccine that will be effective against Ebola. The Canadian government owns the rights to an untested vaccine which, because of the urgent nature of the problem, has been approved for use in African countries where Ebola rages. The Wall Street Journal reports that the World Health Organization (WHO) gave a green light to the use of the drug which was developed at the National Microbiology Laboratory in Winnipeg. The Canadian government said it would donate 800 to 1,000 doses. It has been shown to have promise in animal research. The government has licensed the rights to a U.S. company, BioProtection Systems Corp.
