Smallpox

[mikebratcher69]

If you catch cow pox it gives you anti bodies to fight smallpox, I've had cow pox, caught it at the ever so healty slaughter house. they used to give people cow pox, (milder form of small pox virus) by rubbing pus from a cow pox into a cut on your body thereby giving you cowpox and prepping your imune system for small pox.
They found this out because there was a outbreak of smallpox and the milk maids didnt get it, this was because as theyd already had cowpox they were imune. So dont worry folks just get cow pox and you'll be fine...
