Rabies is not tame. If you get the vaccine for it, you're golden (near perfect efficacy, and you can even get it shortly after contracting rabies because rabies works so slowly).
But as soon as you start showing symptoms, you're dead. Rabies is able to cross the blood brain barrier, but the vaccine for it is not. Once you're showing symptoms, the death rate is 100% (60k die from rabies annually, less than 50 have ever survived after showing symptoms).
The Milwaukee Protocol is not effective.
The death rate rounds to 100%, not 99.99%, and it's not even remotely close (as noted in the parentheses of my original comment).
