Question

Anti-rabies vaccine was discovered by
A. Edward Jenner
B. James Lind
C. Louis Pasteur
D. Robert Koch

Answer 1

Hint: A human body consists of an immune system, which consists of cells that recognize harmful pathogens. The immune system defends the body against these pathogens and removes them.

Step by step answer:A biological preparation that contains agents, which provide active acquired immunity against infectious diseases is known as a vaccine. Vaccination is the administration of a vaccine. These terms were derived from the Variolae vaccine, meaning smallpox of the cow. The four different types of vaccines include live-attenuated vaccines, toxoid vaccines, inactive vaccines, and recombinant vaccines. Live-attenuated vaccines are used to protect against rotavirus, measles, smallpox, chickenpox, yellow fever. Inactive vaccines are used against hepatitis A, rabies, etc. They are given in the form of shots against Flu and Polio. Recombinant vaccines are used to protect from hepatitis B, shingles, etc. to name a few. Toxoid vaccines are used against tetanus and Diphtheria.
-Edward Jenner: Edward Jenner was an English scientist and physician. He pioneered the vaccine concept. He created the world’s first vaccine against the smallpox disease. His work was believed to have saved many lives during his time, than any other work. He was often called “the father of immunology”.
-James Lind: James Lind discovered that scurvy was caused due to vitamin-C deficiency. His work included advancing the practice of preventive medicine and nutrition improvement. He was believed to have conducted the very first-ever clinical trials.
-Louis Pasteur: Louis Pasteur was a French chemist, microbiologist, and biologist. He is well known for his discovery of killing bacteria from wine and milk through pasteurization. The first-ever vaccine for rabies was produced by him.
-Robert Koch: Heinrich Hermann Robert Koch was a German microbiologist and physician. He was the founder of advanced microbiology. The causative agents of cholera, anthrax, and tuberculosis were determined by him.
The answer is C, i.e., Louis Pasteur

Note: The causative agent for Cholera is Vibrio cholera. The causative agent of anthrax is Bacillus anthracis. The causative agent for tuberculosis is Mycobacterium tuberculosis.
