Scripps Research scientists create vaccine against heroin high

ster" heroin by pressing on a lever after several booster shots of the vaccine. Only three of the seven rats that received the heroin vaccine self-administered heroin. In contrast, all of the control rats, including those given the morphine vaccine, self-administered the drug.

The effect of the heroin vaccine "was very dramatic; as dramatic as we have ever seen in experiments of this kind," said Koob. "To have an animal vaccinated and not show a response to heroin is pretty amazing."

The team also found that the heroin vaccine was highly specific, meaning that it only produced an antibody response to heroin and 6AM, and not to the other opioid-related drugs tested, such as oxycodone as well as drugs used for opioid dependencemethadone, naltrexone, and naloxone. "The importance of this," said Janda, "is that it indicates these vaccines could be used in combination with other heroin rehabilitation therapies."

The Scripps Research team has recently begun an exciting collaboration with researchers at the Walter Reed Army Institute of Research to see if it is feasible to develop a dual-purpose vaccine against HIV and for the treatment of heroin addiction in a single shot, Janda said.
