Human Trials Of Anti-Smoking Vaccine Begin

Makarand writes "A Nicotine vaccine that may help smokers to quit has made it to human trials. The vaccine is administered as a series of eight shots -- patients receive two shots per visit during four different visits. The vaccine works by stimulating the human immune system to produce antibodies that bind with the nicotine molecules to form a larger complex molecule which cannot pass through the blood/brain barrier to get into the brain. As a result smokers will not feel the 'high' from the cigarettes they light up and lose interest in smoking. Preliminary studies have shown that this vaccine is safe in humans."
