Endurall-P vaccine is made by Pfizer and is approved by the USDA for use
in dogs and cats. Imrab-3 is *still* the only rabies vaccine tested and
approved for use in ferrets.
That doesn't mean a non-approved vaccine wouldn't actually provide
immunity, but if at all possible, stick with Imrab-3.
If you live in a country where you are unable to get Imrab-3, the (really
old- from 1984) sheet on ferrets I have recommends a killed vaccine of
murine (mouse) origin.
