The vaccine works by producing antibodies that specifically bind to nicotine, and thereby prevent much of the nicotine from entering the brain. This process potentially reduces the pleasurable effects from smoking and reduces the addiction to nicotine.

It's such a novel way of treating an addiction because it's not targeting any part of the brain. It's targeting the molecule itself.
