Scientists Testing Vaccines To Help Smokers QuitResearchers at the University of California, San Francisco, and eight other institutions have just started a major study of a vaccine, called NicVax, that seeks to block the pleasurable sensations of satisfying a nicotine addiction.
The vaccine would stimulate production of antibodies that would latch onto nicotine molecules and prevent them from reaching the brain.
The effort to find a nicotine vaccine is part of an emerging wave of research into vaccines against addictive substances. Researchers and pharmaceutical companies are also investigating vaccines that would generate antibodies against cocaine, heroin, and methamphetamine.
Even if the trial of the nicotine vaccine proves successful, it would take at least two years before the product reaches the market, researchers said.
