vaccine developed at the Medical College Weill Cornell, where experimental animals has successfully demonstrated the ability of the liver with the help of a new drug to produce antibodies that neutralize nicotine.Scientists have long conducted work in this direction, ensuring that the body itself purifies the blood of the poison.
Under the influence of the vaccine body creates its own antibodies and developing immunity against nicotine addiction.Drugs that have been tested previously required costly repeat repeated injections.It was difficult to calculate the dose and funds, as their action was strictly individual.
The new vaccine will be the salvation for smokers who have experienced all the existing variants of the fight, but were defeated.According to statistics, about 80% of people who quit smoking, again returned to
Scientists are constantly seeking new ways of how to make the body to give up nicotine addiction.Before a new drug, there are two types of vaccines: active and passive.The first type is a foreign agent for the human immune system, the body sees the "spy" and produces antibodies against it.But the tiny molecules of nicotine is not built into an active vaccine.The second type - a passive vaccine from a whole range of ready-made antibodies, which are necessary for the development of immunity.
Research Department Weill Cornell has developed a third kind - a genetic vaccine.Scientists have designed antibodies that neutralize nicotine, and put them into a virus, does not have a negative impact on the person.After interacting with the genetic vaccine liver cells begin to produce its own antibodies, and in large quantities.
Most importantly, only a very small part of the poisonous nicotine reaches the brain of the smoker.As a result, a person does not get what he expects from cigarettes, but without the fun is lost the very meaning of this bad habit.The vaccine can be used as a prophylactic to prevent the occurrence of nicotine addiction.
vaccine on humans has not yet been tested in the queue - rats and primates, but mice that participated in the experiment, do not feel worse than before it began.
