Scenarios about 'vaccines'
The development of biological preparations that provide acquired immunity against specific diseases. Vaccines have dramatically altered human history by reducing or eliminating deadly diseases like smallpox and polio, with their discovery tracing back to Edward Jenner's pioneering work in 1796. In alternate history scenarios, different timelines of vaccine development could profoundly impact population demographics, military outcomes, and the course of civilizations by changing mortality patterns and public health trajectories.
