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."
