“A vaccine to treat heroin addiction has proven effective in keeping drug-addicted rats from relapsing in a preclinical trial, according to a study published this week in Proceedings of the National Academy of Sciences. Researchers from the Scripps Research Institute in California say the vaccine is now ready for human trials.
Initial research into the vaccine in 2011 found that it could effectively keep rats from becoming addicted to heroin without affecting the pain relief they experienced from other opiates. This study built on those results using rats that were already addicted, finding that the vaccine could keep them from resuming compulsive drug-taking behavior even after they experienced withdrawal.”
