The researchers do not know how often the vaccine needs to be administered in humans to maintain its anti-cocaine effect. One vaccine lasted 13 weeks in mice and seven weeks in non-human primates.

“An anti-cocaine vaccination will require booster shots in humans, but we don’t know yet how often these booster shots will be needed,” says Dr. Crystal. “I believe that for those people who desperately want to break their addiction, a series of vaccinations will help.”
