Abstract
Novel hapten-carrier conjugates are capable of inducing the production of antibodies, in vivo, that specifically bind to nicotine. These conjugates comprise a nicotine hapten conjugated to an immunogenic carrier protein. The novel conjugates preserve the chirality of nicotine in its native (S)-(-) state, and have good stability properties. The conjugates are useful in formulating vaccines for active immunization, that are used to prevent and treat nicotine addiction. The antibodies raised in response to the nicotine hapten-carrier conjugate are used for passive immunization. These antibodies are administered for prevention and treatment of nicotine addiction.
