- Alexander Fleming is incorrect: Alexander Fleming is credited with the discovery of the enzyme lysozyme in 1923 and the world's first antibiotic substance, benzylpenicillin (Penicillin G), in 1928.
- Edward Jenner is correct: Edward Jenner is credited with the discovery of the vaccine for smallpox. In 1796, he demonstrated that inoculation with cowpox matter provided immunity against smallpox. He published his findings in 1798. He is often referred to as the "Father of Immunology."
- Robert Koch is incorrect: Robert Koch is considered one of the founders of modern bacteriology. He is known for identifying the specific causative agents of tuberculosis, cholera, and anthrax and for creating Koch's postulates.
Key Takeaway: Edward Jenner developed the first vaccine (smallpox) in 1798, laying the foundation for the field of immunology.
