Louis Pasteur was the first person who uses the live virus in vaccination and developed the method for the attenuation of virulent microorganisms that is the basis of vaccination. He developed vaccines against cholera, anthrax and rabies. Thus, the correct answer is option C.

Louis Pasteur and Emile Roux developed the first rabies vaccination in 1885. This vaccine was first used on a human on July 6, 1885, on nine-year-old Joseph Meister, who had been bitten by a rabid dog.

Rabies is a viral disease that causes acute inflammation of the brain. Rabies is caused by lyssaviruses including: rabies virus and Australian bat lyssavirus. Rabies is spread when an infected animal scratches or bites another animal or human. Hydrophobia (fear of water) is the historic name for rabies. It refers to a set of symptoms in the later stages of the infection in which the person has difficulty swallowing, shows panic when presented with liquids to drink, and cannot quench his or her thirst. Any mammals infected with the virus may demonstrate hydrophobia. 

The rabies virus is transmitted to others through the saliva of the infected animal. All mammals can carry the virus. Humans can contract the virus through a bite from the infected animal, or from a scratch, scrape, open wound, or mucous membrane that comes in contact with the saliva. It is not possible to contract the virus by petting a rabid animal or through contact with the blood, urine, or feces of a rabid animal.

Most rabies cases are found in domestic animals, such as the dog or cat. But with the rabies vaccine now required for pets and livestock, most rabies animal cases today are found in wild animals and stray dogs. It is found most often in raccoons, skunks, bats, foxes, and coyotes. Rarely it is found in rabbits, squirrels, rats, and opossums, although it is becoming more common in groundhogs. Raccoons are a concern because they often interact with household pets.

Rabies infection is caused by the rabies virus. Rabies is a life-threatening condition that causes tens of thousands of deaths worldwide every year. Dogs are the most common source of transmitting the virus along with cats and wild animals like raccoons and bats. They are able to transfer the virus to humans via bites and scratches. 

Rabies infection is caused by the rabies virus. Domestic dogs, cats, and rabbits, and wild animals, such as skunks, raccoons, and bats, are able to transfer the virus to humans via bites and scratches. The virus causes the inflammation of the brain in humans and mammals. it affects the central nervous system.

Animal control and vaccination programs have decreased the risk of rabies from dogs in a number of regions of the world. Immunizing people before they are exposed is recommended for those who are at high risk. Immunoglobulins are effective in preventing the disease if the person receives the treatment before the start of rabies symptoms.

Rabies is a life-threatening condition that causes tens of thousands of deaths worldwide every year. It’s caused by a virus that attacks the central nervous system. The virus is transmitted to humans via bites and scratches from infected animals. The symptoms of rabies can present themselves just a few days after a bite, or they might take as long as 12 weeks. The common symptoms includes fever, headache, nausea and fear of water due to difficulty in swallowing (hydrophobia), insomnia etc.
