Earlier, Kim Yanda and his staff have already tested on animals a drug created based on a protein that can block heroin from entering the brain. With the use of adenoassociated virus, they attempted to modify cells in such a way that they began to constantly produce blood antibodies that provide such blockage. According to published on the website of the American magazine Human Gene Therapy data they managed it.
Earlier this year, scientists from the “National Institute of Psychiatry named after A. Ramona de Fuente” in the Mexican capital (Mexico City). They too did animal studies and started human trials of the vaccine. In Mexico, it is believed that the drug should appear on the market within the next five years.
Previously, the creation of a similar vaccine was reported by Spanish researchers. In 2009, as part of the “National Drug Plan”, clinical trials for the cocaine addiction vaccine began in that country. The recruitment of 170 volunteers in 10 hospitals in Spain was reported in the press. Back then, it wasn’t about drug abuse prevention, it was about applying the vaccine to clinic patients already addicted to drugs.
