Figure 1. Oral rabies vaccines can be helpful in vaccinating dog populations where traditional parenteral methods have failed to reach adequate vaccination coverages, Haiti. A) A dog hiding behind 2 buildings is vaccinated with an oral rabies vaccine. B) A family with 4 free-roaming dogs watches as they ingest an oral rabies vaccine bait. C) Dogs can be protective of puppies, so oral rabies vaccines provide a safer method to vaccinators and reduce the risk of bites during parenteral vaccination. D) Fences and other barriers can make difficult tasks for parenteral vaccinators. A dog is vaccinated through a barbed wire fence with an oral rabies vaccine.
