In Russia, a 26 year old man died of rabies after having been bit (3 months ago) by his pit bull terrier. Doctors had dismissed the possibility of rabies after he began experiencing neurological disorders, on the grounds that his dog had been "vaccinated." The dog ended up dying but no autopsy was performed to find out he cause of death. In retrospect, the vaccine was probably an "unregulated imported" one. I didn't think that there would be a black market for rabies vaccines, but I guess because they're so expensive, it would probably be profitable.
