Final answer:
Rabies is a deadly disease caused by the rabies virus. Vaccination can be given successfully after exposure to the virus.
Step-by-step explanation:
Rabies is a deadly zoonotic disease caused by the rabies virus (RV). It is primarily transmitted through the bite of an infected mammal. The disease progresses slowly, allowing time for the immune system to develop antibodies against the virus. Vaccination can be given successfully after exposure to the virus, which means option 3: After, is the correct answer.
