American scientists from a number of research centers and universities in Houston and New Orleans have developed the world's first vaccine…which blocks the drug fentanyl from entering the brain of rats, thus preventing the development of addiction, Pharmaceutics reports.
Specifically, it refers to opioids associated with an increase in the number of disorders and fatal overdoses. Experts note that despite the fact that drug addiction is treatable, 80% of people suffer from relapse.
The vaccine is able to generate antibodies against fentanyl that bind to consumed fentanyl and prevent it from entering the brain, allowing it to be eliminated through the kidneys, said Colin Hale, associate professor at the University of Houston.
Importantly, the vaccine did not block the effects of other opioids. This suggests that it would not interfere with pain relief in people if other opioids were used.

What is more important to note is that, a general drug antagonist already exists in the market place that works on most all drugs, not just Fentanyl in preventing addiction relapse See Naltrexone
