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.
