The Zoonosis Control Division's Oral Rabies Vaccination Programs (ORVP) were created to eliminate rabies in coyotes (Canis latrans) in South Texas and rabies in gray foxes(Urocyon cinereoargenteus) in West Central Texas. Both the South Texas Program and the West Central Texas Program utilize an oral rabies vaccine encased into a bait matrix. The vaccine/bait units are distributed aerially along transect lines. This ensures a consistent coverage of the target area. Each of the Programs has its own variation of bait matrix and bait/vaccine unit distribution density adapted for the individual target species.
