12 Jan 1796 Jahr - Smallpox/Germ Theory

Beschreibung:

Edward Jenner notices milk maids don't get sick of smallpox and wonders why. Found Cows got sick with their own Pox. Jenner tests Cow-Pox on James Phillips and gives him a small dose. Phillips doesn't get Smallpox. This is known as Vaccination where you give a very small dose of the disease and introduce it into the immune system which then develop antibodies for it and was the first reported case of such thing.
