(Newser) – A new study has given fresh hopes that a one-shot vaccine could inoculate a person against nicotine addiction.

The gene was injected into their livers, which acted as a factory by pumping out a steady stream of the antibodies.

The vaccine will need to undergo more testing on mice before making the leap to humans. "This is a new strategy that may work," the study's senior author said. "We won't know until [we] do the human studies, but it is a very difficult problem and we need new strategies." But don't get your hopes up too high; two past attempts at a nicotine vaccine have failed when tried on humans. (Read more cigarettes stories.)
