Quitting smoking made possible using anti-nicotine vaccine.
Are you a chain smoker and not able to kick the habit? A new vaccine could help.
Swiss scientists have developed a vaccine that blocks the pleasure factor in smoking leaving the smoker with no kick, reports news portal Annanova.
The anti-nicotine injection, CYT002 - NicQb, patented by Swiss pharmaceutical firm Cytos, works by building antibodies in the blood that stop nicotine from getting to the brain, it said.
The vaccine has so far proved to be successful as it has already passed one preliminary test.
Forty percent of the participating smokers quit within nine months since being injected with the drug.
University of Lausanne professor Jacques Cornuz, who helped develop the anti-nicotine injection, said: "The results have exceeded our expectations."
Before the injection the participants had all smoked between 10 and 40 cigarettes a day.
The vaccine is expected to be in the market by 2010.
There are about 1.3 billion smokers worldwide and tobacco causes at least five million deaths, according to the World Health Organisation (WHO).
