Reminds me of efforts around edible rabies vaccines that they have dropped in the wilderness to vaccinate wild animals. The big hold up there is how to get the bats vaccinated too. I've seen some studies into vaccines that are designed to stick to the bat and that will spread to its friends while they groom each other.
It would be great if governments put a bunch of effort into eradicating these diseases.
I've heard of some experimental attempts to apply permethrin to the necks of deer using bait stations where the deer have to put their head+shoulders into a narrow treated area to get to the food. Doesn't seem to have seen commercialization.
