Jean Lilly has been a smoker for 25 years and she's starting to feel the effects. "Shortness of breath from smoking making my lungs hurt." She's tried everything to quit. "I've tried just cutting back to a certain amount a day or just cutting cold turkey. It's just -- you think about it more," she says.

But enough is enough. She's says she's done with cigarettes. That's why she's enrolling in a phase three trial headed by Doctor Robert Jeanfreau. He's testing a vaccine showing promising results by helping people quit smoking. "Even now, after all this time, after all the terrible things that cigarette smoking does to people, people still smoke," he says. Doctor Jeanfreau says the vaccine is an injection that produces antibodies that bind to nicotine when you smoke, killing the addiction. "It won't give you the effects you get when you smoke, so people will eventually stop smoking because they're not getting that same sensation that they normally get."

Doctor Jeanfreau says participants will get six injections over 26 weeks -- and so far, there haven't been a lot of significant side effects. He says the vaccine is very hopeful. "One of the single most important things a smoker will do from a health standpoint is to stop cigarettes."

Jean is excited. "I'm all for it. Anything to help quit." She's about to be a grandmother -- and wants to be around for a long time.

If you're a smoker with no health problems between the ages of 18 and 65, you may qualify to participate in the study. To enroll, call Benchmark Research at 1-800-369-2875.
