The study, published in the journal Science Translational Medicine describes that a single dose of the novel vaccine protects mice against a life-long addiction against nicotine. <\/p>\n
The vaccine uses the animal's liver as a production site to continuously produce antibodies that instantly gobble up nicotine the moment it enters the bloodstream, and therefore prevents the chemical from reaching the brain and heart. <\/p>\n
Leading researcher, Dr. Ronald G. Crystal, chairman and professor of Genetic Medicine at Weill Cornell Medical College explains: <\/p>\n
He continues saying: \"Our vaccine allows the body to make its own monoclonal antibodies against nicotine, and in that way, develop a workable immunity.\" <\/p>\n
Dr. Crystal stated that the reason why earlier nicotine vaccines failed in clinical trials was because they all directly deliver nicotine antibodies. Their effect only lasted a few weeks and therefore required repeated, costly injections. He adds that this impractical, passive vaccine also delivered inconsistent results, which could potentially be because each person may require a different dose, particularly if the person starts to smoke again. <\/p>\n
Crystal says: <\/p>\n
He adds that evidence has shown that 70 to 80% of smokers who try to quit pick up the habit again within six months. <\/p>\n
Around 20% of American adults smoke, and what keeps smokers addicted is the nicotine in the tobacco, and not the 4,000 chemicals in the burning cigarette that cause smoking-related health problems and which lead to one in every five deaths in the U.S. <\/p>\n<\/p>\n
