The correct answer is
Anthrax

Understanding the First Microorganism Disease and Vaccine

This question asks to identify the first human disease that meets two specific criteria: being conclusively proven to be caused by a microorganism, and being the first against which an effective vaccine was developed.

Anthrax: The Historical Milestone

Anthrax is the correct answer as it uniquely satisfies both conditions:

  • Proof of Causation: In the 1870s, Louis Pasteur conclusively proved that Anthrax was caused by the bacterium Bacillus anthracis.
  • First Effective Vaccine: Pasteur also developed the first effective vaccine against Anthrax, a significant breakthrough in preventive medicine.

While other diseases were later linked to microorganisms or had vaccines developed, Anthrax holds the distinction of being the first for both milestones.
