NORMAN, Okla. - Three people have died and at least 61 injured so far this year as cases of the West Nile virus increase in the U.S.
Researchers at the OU Health Sciences Center say early tests for a vaccine against the virus look promising.
Dr. James Papin and other OU researchers are able to isolate strains of the virus and then use a chemical which renders it harmless.
"We know that we can do it, and we know through lab models that it can actually -- looks like it can protect against infection," Papin said.
Researchers are now in the process of developing the actual vaccine, which would then be followed by years of testing before it is available on the market.
