Rabies is an overwhelmingly fatal disease, with only a few documented survivors. There is no effective curative treatment for rabies once clinical signs have appeared. All cases of suspected rabies exposure should be treated immediately to prevent the onset of clinical symptoms and death. Post-exposure prophylaxis (PEP) consists of wound treatment, the administration of rabies vaccines based on WHO recommendations, and if indicated, the administration of rabies immunoglobulin (See table below).
Will there ever be an effective rabies treatment?
This treatment includes extensive washing and local treatment of the wound followed by a course of a potent and effective rabies vaccine. When given in time, PEP can stop the rabies virus from entering the central nervous system and, in turn, prevent the onset of rabies symptoms.
Can you cure rabies?
Why is rabies not curable? During infection of the brain, the permeability of the barrier can increase, allowing immune cells and antibodies through to help clear the infection. However, during infection with rabies virus, the blood brain barrier locks down, meaning nothing can get through, even antiviral drugs.25 Has anyone been cured rabies?
Why is rabies not curable?
- Vaccinating dogs, cats, and ferrets against rabies
- Keeping pets under supervision
- Not handling wild animals or strays
- Contacting an animal control officer upon observing a wild animal or a stray, especially if the animal is acting strangely

Rabies vaccine - Wikipedia
Virtually all infections with rabies resulted in death until two French scientists, Louis Pasteur and Émile Roux, developed the first rabies vaccination in 1885.Nine-year-old Joseph Meister (1876–1940), who had been mauled by a rabid dog, was the first human to receive this vaccine. The treatment started with a subcutaneous injection on 6 July 1885, at 8:00 pm, which was followed with 12 ...

Abstract
Rabies is an acute, fatal, neurological disease that affects almost all kinds of mammals. Vaccination (using an inactivated rabies vaccine), combined with administration of rabies immune globulin, is the only approved, effective method for post-exposure prophylaxis against rabies in humans.
1. Introduction
Rabies is an ancient neurological disease caused mainly by the rabies virus (RABV) and is almost invariably fatal once clinical symptoms develop. Currently, rabies continues to pose a serious public health threat in most areas of the world, especially in the developing countries of Asia and Africa.
2. Brief History of Classical Rabies Vaccines
Rabies is one of the oldest infectious diseases and has been known to mankind for more than 4000 years [ 11 ]. However, it was not until 1885 that Louis Pasteur developed the first RABV vaccine from the spinal cord of rabbits infected with rabies that was air-dried for inactivation.
3. Live-Attenuated Virus-Based Rabies Vaccines
Unlike most other vaccines, however, rabies vaccines are designed to be prophylactic and administered primarily in a post-exposure manner. Due to the extremely high mortality of rabies, only inactivated rabies vaccines were approved for human rabies control.
4. Other Novel Modalities for Rabies Control and Prevention
Although live-attenuated virus-based vaccines represent the most promising approach for rabies control and treatment, some other novel modalities have also been investigated for their potential role in rabies treatment, such as protein and peptide vaccine, nucleic acid-based vaccine, RNA interference (RNAi), and RIG, coupled with BBB permeability enhancing agents such as monocyte chemotactic protein-1 (MCP-1).
5. Conclusions
Rabies continues to pose a severe burden to public health and is ranked one of the most fatal diseases. It causes tens of thousands of human deaths annually, particularly in developing countries. Currently, dogs remain the main source of rabies and are responsible for almost 99% of fatal rabies cases in humans.
