Show answer
Correct answer: C. Edward Jenner
Explanation
The correct answer is C, Edward Jenner. In 1796 Jenner showed that material from a cowpox sore protected a boy against smallpox, the first deliberate vaccination, and the word vaccine itself comes from vacca, the Latin for cow. That experiment founded the science of immunology. Option A is wrong because Robert Koch identified the bacteria that cause tuberculosis and cholera and gave the rules for linking a microbe to a disease, so he belongs to bacteriology. Option B is wrong because Louis Pasteur gave the germ theory of disease, pasteurisation and the rabies vaccine, and is called the father of microbiology, although his vaccine work came after Jenner. Option D is wrong because Karl Landsteiner discovered the human blood groups. The trap in this question is Pasteur, whose fame in vaccines makes candidates skip the earlier name.
