Question

Who initially developed the vaccine for rabies in a man?
(a) Robert Koch
(b) Joseph Lister
(c) Louis Pasteur
(d) Stanley

Answer 1

Hint: Biological preparation formulated to provide acquired immunity for a particular disease is called a vaccine. The vaccine contains a weakened or killed form of the disease- causing agent, its surface proteins, or its toxins.

Complete answer:
- Louis Pasteur produced the first vaccine for rabies by growing the virus in rabbits. He was the first scientist to artificially attenuate viruses for use in vaccines.
- The virus becomes more adapted to particular species and less adapted to its host when the serial passage of the virus through that species is made.
- By passing the virus through rabbits, Pasteur made the virus less dangerous to human hosts while still giving the body enough information to recognize the antigen and develop immunity.
- Louis Pasteur created several veterinary vaccines before his development of the rabies vaccine in 1885 for use in humans.
Additional information:
- Rabies is among the most terrifying viruses to get. According to the centers for disease control, once clinical signs of rabies appear, the disease is nearly always fatal.
- Pasteur successfully protected dogs from the disease, and then he agreed to treat his first human patient.
- Nine- year- old Joseph meister was the first human to receive the rabies vaccine in 1885.
- The first vaccine was derived from the spinal cord of an inoculated rabbit that died of rabies 15 days earlier.
- All the doses were obtained by attenuation.
- Virus attenuation was done by allowing the harvested virus samples to dry for five to ten days.
Robert Koch: He was one of the founders of bacteriology who discovered the anthrax disease cycle and the bacteria responsible for tuberculosis and cholera.
Joseph Lister: He was a British surgeon and medical scientist who was the founder of antiseptic medicine and a pioneer in preventive medicine.
Stanley: Stanley was a chemist who experimented with tobacco mosaic virus (TMV), which causes spots on the leaves of infected plants.
So, the correct answer is ‘Louis Pasteur’.

Note: The process of administration of vaccines is called vaccination.it is responsible for the eradication of many diseases. Rabies is caused by viruses that mainly live in animals. Pain fatigue, headaches, fever are some of the symptoms of rabies followed by seizures, hallucinations, and paralysis.
