Colorado Parks Explores Vaccination to Protect Prairie Dogs from Plague
New research from Colorado Parks and Wildlife and its partners shows that treating prairie dog colonies annually with a flea-killing dust or an oral vaccine can prevent their complete collapse when confronted with plague.
In a three-year study conducted in northern Larimer County, dusted or vaccinated prairie dog colonies survived during plague outbreaks while nearby untreated colonies were devastated. Neither treatment was completely effective at preventing plague, but some prairie dogs did survive in the colonies treated prior to plague outbreaks.
