By using gene therapy to create a novel antibody that gobbles up nicotine before it reaches the brain in mice, scientists say they may have found a potential smoking vaccine against cigarette addiction. However, there is still a long way to go before the new therapy can be tested in humans.In a study reported in the journal Science Translational Medicine this week, Researchers at Weill Cornell Medical College in New York City show how a single dose of the vaccine protected mice, over their lifetime, against nicotine addiction.
