• B. Louis Pasteur
• C. Dr. Edward Jenner
• D. Robert Koch

Answer: (C)

Dr. Edward Jenner is recognized as a pivotal figure in the development of vaccination during the 18th century. His groundbreaking work involved the use of cowpox material to create immunity to smallpox, a prevalent and deadly disease at the time. Jenner's experimentation in 1796 demonstrated that inoculating individuals with cowpox led to protection against smallpox, effectively laying the foundation for immunology and the practice of vaccination as a means of disease prevention. This innovative approach led to widespread vaccination efforts, ultimately contributing to the control and eventual eradication of smallpox in the late 20th century. Jenner's successful demonstration of vaccination principles marked a significant advancement in public health and influenced future vaccine development.
