Researchers at Yale University have developed a “cocaine vaccine” which neutralizes the “feel-good” effects of the drug.
The vaccine is called TA-CD, and Dr Thomas Kosten, chief researcher, claimed that when injected it produces cocaine-specific antibodies which block the drug before it reaches the brain. Yet TA-CD will not prevent drug cravings, and can be defeated by consuming larger quantities of cocaine.
More extensive studies of the vaccine are now underway. It is being developed by British-based Cantab Pharmaceuticals.
