A vaccine to treat heroin addiction has shown promise in rat studies, but faces challenges including a lack of funding, Time reports.
Researcher Kim Janda at the Scripps Research Institute in La Jolla, California, says drug companies are not interested in addiction vaccines. He has been studying treatments for heroin and methamphetamine addiction, as well as cocaine overdoses.
“No pharmaceutical company is going to fund trials for heroin, no way,” Janda said. “For meth? No way. Forget about it.” Janda is most hopeful about the heroin vaccine. “The heroin one has been our best success in over 25 years of working—it’s the best data we’ve seen,” he noted.
