Nicotine Vaccine... WTF?!

While browsing the news sites, I stumbled upon this Nicotine Vaccine video on Reuters. Nicotine (smoking)... Vaccine? Since when is smoking caused by a virus?

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

What's next? A vaccine for Kleptomania? Bad driving? Being obnoxious? This is (in my opinion) nothing more than an effort of Big Pharma to have us take more and more drugs. They have to do something to keep their investors happy since more and more drug patents are expiring.
