Smoking is obviously very bad for your health, tobacco cultivators, and even the environment. WIth that in mind, it’s great to see that research into a nicotine vaccine is underway and is seeing some success.

Rennard said patients who produced the most anti-nicotine antibodies were also the ones most likely to stop smoking for longer. And if they did not quit, they smoked less — 10 cigarettes on average a day, compared with 20 before they got the vaccine.

“This development is key for the field of smoking cessation research and could have a significant impact on how we treat patients with nicotine addiction,” said Rennard, who presented his findings to a meeting of the American Heart Association in Orlando, Florida.
