It's a drag, day after day for Michael Harwood, 41 years of smoking cigarettes.

It's time I need to stop. They're gonna kill me young if I don't.

Right now he puffs1 a pack and a half a day. At his peak, it was about 4 packs a day while drinking alcohol. By his own account, he's tried to quit 10 times; his longest streak2 without a smoke is 3 days.

Inside I don't feel well. My lungs have been bothering me. I get bronchitis quite a bit.

That's why he is here at the University of Wisconsin Center for Tobacco Research and Intervention3. Howard is participating in a nicotine4 vaccine5 study. Doctor Douglas Jorenby is leading the research on the new vaccine called NicVax.

Rather than working on pathways in the brain, it's keeping nicotine from getting there in the first place. And the thought is that that may make it easier for people to quit smoking if they are not experiencing the,the pleasurable effects of it.

Harwood is getting his first shot. Over the period of a year, he will get 4 or 5 injections and keep track of his vital signs daily with an electronic diary. The vaccine is not approved by the FDA. But Doctor Jorenby is looking forward to the results of the study.

The preliminary data we have is that it's gonna be a good way to quit smoking. I don't think we're ever gonna find a magic bullet.

The study will enroll6 300 people around the country including 30 right here at the University of Wisconsin. 2/3 of the smokers7 in the study will get the vaccine and the other 1/3 will receive a placebo8 shot. Neither Harwood or the Doctors will know what shot he's getting until the end of the study. He hopes NicVax is the key to unlocking his nicotine addiction9 since less than 10% of smokers successfully quit.
