“ WE WERE ABLE TO BLOCK EXTREMELY LARGE - Paul Bremer DOSES OF FENTANYL TO PROTECT AGAINST OVERDOSES
SAFE AND POWERFUL Not only was the vaccine able to stop intoxication (something researchers suggest could aid in opioid addiction treatment), the vaccine also proved extremely effective in blocking the potentially lethal effects of fentanyl as well. While the chemical is not necessarily toxic in itself, it does produce psychoactive effects that can shut down breathing and stop a person’s heart. Researchers say mice injected with the vaccine could withstand doses of fentanyl up to 30 times the normal rate. “It was just a first generation vaccine, but it did prove to be very potent,” Bremer says. “We were able to block extremely large doses of fentanyl to protect against overdoses.” A SINGLE PURPOSE Researchers say the vaccine would not protect against heroin or oxycodone, and a mixture of vaccines would be needed to protect against all opioids. But that was somewhat by design. To make sure the vaccine would not interfere with any medications a person may take responsibly later in life, researchers targeted specific molecules so the vaccine would only block fentanyl and its derivatives.
“For unrelated drugs that you would be taking, there would be no effect from the vaccine,” Bremer says. LOOKING TOWARD THE FUTURE Although still in the early stages of development, researchers say the vaccine represents an exciting step forward in drug vaccine research. The lab is beginning more advanced trials on a similar heroin vaccine which should give them a better idea of how successful the fentanyl vaccine could become. But until more testing can be completed, researchers say they were pleased with the progress and excited for the future of vaccines in the treatment of addiction. “This concept of using a vaccine for addiction isn’t just an academic pursuit, it could really be used in practice,” Bremer says. “I think it’s really promising.”
