Anti-smoking Vaccine - ABC 33/40 - Birmingham News, Weather, Sports

People may one day be able to get a shot to resist smoking.

Scientists may have developed a vaccine against nicotine addiction.

So far, they've only tried it in lab mice.

The vaccine uses the shell of a harmless virus to carry genetic instructions into cells to make an antibody against nicotine.

When cells are "infected" by the virus, they're tricked into churning out a protein that blocks nicotine's biological effects.

This time, researchers may have found a way to get the body to keep making more of the antibodies.
