Abstract
A vaccine against nicotine may soon be available to smokers who want to quit. The vaccine stimulates the production of antibodies that bind to nicotine, thereby impeding nicotine from crossing the blood-brain barrier and exerting psychoactive effects. The primary purpose of this study was to evaluate intentions to try a nicotine vaccine if one were to become available among a nationally representative sample of smokers. The secondary purpose was to assess whether information about genetic susceptibility to nicotine addiction had an effect on smokers’ interest in receiving the vaccine.
Four hundred and twenty-seven adults were randomized to read one of two versions of a short description about the vaccine. One version framed addiction as genetically influenced, while the other framed it as environmentally influenced. Smokers were then asked about their intentions to use a nicotine vaccine if one were to become available in the future.
Across both groups, 53% indicated that they would be likely or very likely to try the vaccine. Using multivariate linear regression, the strongest predictors of vaccination intention were having a favorable attitude toward a nicotine vaccine (β = .41) and having a favorable attitude toward vaccination in general (β = .22). There were no significant effects of the framing conditions on intention to receive the vaccine.
Intentions to try a nicotine vaccine as a cessation method are relatively high among smokers. If the vaccine becomes available, specific groups of smokers may be more interested than others; education and recruitment efforts could be targeted appropriately.
