Wildlife biologists say if rabbits disappear coyotes will begin hunting other animals...such as sheep, goats, cattle and the like.
Rabbits are an essential part of the environment since they are plentiful and grow quickly. You can’t just pluck an entire order of animals out of the environment without having bad effects.
The Portuguese are working on an oral vaccine that can be put in bait:
“Four institutions in Portugal are working on a different approach. Project Fight 2 aims to develop an oral vaccine for RHDV2, incorporated into bait, for the wild rabbit populations of the Iberian Peninsula.”

Thanks for the link. I imagine that resistant rabbits eventually will emerge and then the population will revive naturally. Rabbits have been around for a very long time.
