If all goes as planned in an upcoming human trial of a potential heroin vaccine, a new weapon may soon be available to combat heroin addiction in drug users.
Researchers at the country’s National Institute of Psychiatry say they have successfully tested the vaccine on mice and are preparing to test it on humans to see if it exhibits the same beneficial effects.
“It would be a vaccine for people who are serious addicts, who have not had success with other treatments and decide to use this application to get away from drugs,” the institute’s director Maria Elena Medina said in Mexico City on Thursday.
The Scripps Research Institute in California, which has also seen success of its heroin vaccine in lab rats, is currently conducting human clinical trials for cocaine and nicotine vaccines, but not heroin.
The Mexican researchers will be the first to test a heroin vaccine in humans. The scientists are hopeful a breakthrough is on the horizon, as their vaccine appears promising.
Health Secretary Salomon Chertorivski earlier projected that the vaccine will not be ready for human use for five years. However, that estimate may be a conservative one now that country is set to begin human trials.
However, the Mexican scientists appear to be close to making a breakthrough on a heroin vaccine.
During the tests, mice were given access to deposits of heroin over an extended period of time. Those given the vaccine showed a huge drop in heroin consumption, giving the institute hope that it could also work on people, Maria Elena Medina said.
Mexico, a major producer and transit country for drugs smuggled into the US, has a growing drug addiction problem and grapples with relentless drug-related violence. Health Secretary Jose Cordoba recently said the country has some 450,000 hard drug addicts.
