Wyoming testing chronic wasting disease vaccine

The Wyoming Game and Fish Department is testing how well a vaccine for chronic wasting disease will work in elk. The vaccine being tested was developed by three Canadian infectious disease centers. The vaccine is being tested on 25 elk calves transported from Game and Fish's South Park feedground to the Thorne-Williams Wildlife Research Unit in Wheatland. State wildlife veterinarian Terry Kreeger says 25 more elk calves taken from the feedground will be left at the facility unvaccinated as a control group. Kreeger says the hope is that the vaccinated elk will live longer. Chronic wasting disease is a fatal neurological disease found in elk and deer. It could take years to determine whether the vaccine is effective.
