did you know by repeatedly injecting super small amounts of certain poisons your body can develop immunity to it?
You can never be truly immune to poisons, you can be resistant to it, but never immune to its effects. For instance nicotine is a poison that develops on the leaves of Tobacco plants, when smoked the lungs provide adequate resistance to the smoke and nicotine where it is processed and diluted in mucous and lung membranes, giving that slight feeling of satisfaction. Yet if you get about an oz of tobacco and extract the nicotine, only two drops in someones drink can kill them, even if they are a lifetime smoker with "resistance" to the poison. Even with poison ivy, you can get poison on your skin and develop resistance to the chemical, but if you extract it you're going to be in a load of pain.
Vaccines are completely different, don't get them confused with resistance. Immunity is a very very complicated system which isn't taught in high school.
