; Adaptive Landmarks
: '''Smallpox and Cowpox (1796)''' → Edward Jenner noticed that milkmaids who got "Cowpox" were immune to "Smallpox," discovering the first way to "Cheat" the adaptive system through vaccination.
: '''The Discovery of B and T Cells (1960s)''' → The breakthrough that finally explained why we have "Two" immune systems and how they work together.
: '''HIV/AIDS''' → A virus that specifically attacks the **Helper T-cells**. By killing the "Generals," the virus leaves the whole immune system paralyzed, showing how vital the adaptive coordination is.
: '''Passive Immunity''' → When you get antibodies from someone else (like a baby getting them from its mother's milk), providing temporary protection without the body needing to "Learn" the germ.
