The “cure” for rabies is to treat it with a vaccine prior to symptoms appearing. The rabbies vaccine is 100% effective and you will not become symptomatic if you treat soon after the bite. The Milwaukee protocol has been tried and it’s a last ditch effort for people who didn’t get the vaccine shortly after the bite and are now showing symptoms. They don’t even know if the Milwaukee Protocol is what prevented death or if the people it worked on were somehow resistant to rabies.
