Wildlife Rabies Vaccine

FILE - Oral rabies vaccine bait that will be dropped by a state police helicopter from the New York State Police Aviation Unit in Albany and team members of the State Health Department is displayed during a rabies vaccine bait drop over the Northeastern part of the state during the New York State Department of Health Racoon Vaccination Project, Monday, Aug. 20, 2007. The U.S. government has begun scattering millions of packets of oral rabies vaccine from helicopters and planes over 13 states from Maine to Alabama. The major aim is to keep raccoons from spreading their strain of the deadly virus to states where it hasn't been found or isn't widespread, said field trial coordinator Jordona Kirby.
