NicVax, Vaccine For Smoking

But it still needs some time around two years to be able to reach on the market.

The vaccine would stimulate production of antibodies that would latch onto nicotine molecules and prevent them from reaching the brain.

The anti-nicotine antibodies generated by NicVax are proteins that bind to the nicotine molecule. Because the compound is too big to cross the blood-brain barrier, the vaccine is expected to diminish or eliminate the pleasure associated with puffing a cigarette. This lack of positive physiological reinforcement for smoking is believed to reduce the nicotine craving that causes smokers to fail in their efforts to quit.
