Now, this is another area in which much work is underway. The idea being that if a infection rate of rabies in reservoir species is decreased, then transmission to other species, pets and humans included, could be limited.
Vaccination is the best way to limit rabies infection and therefore transmission.
Individual injection of a vaccine is both time consuming and on a grand scale not practical. A method that is less labour intensive is attractive. Oral vaccination, through ingestion of a vaccine placed in an appealing edible form, is thought to be the most practical method to immunize wildlife. Studies are underway to try to find the most effective form of vaccine and how to make these vaccines the most appealing to the target wildlife, plus to ensure safety for expected and unexpected recipients.
