Northwest researchers move toward fentanyl vaccine to prevent overdoses and aid recovery

UW researchers have developed a fentanyl vaccine that triggers antibodies to block fentanyl from entering the brain, potentially reducing overdoses and aiding recovery. They plan to file an FDA IND to begin human trials, while vaccines for oxycodone and heroin are already advancing, and they aim to develop multi-drug vaccines to counter emerging substances, viewing the vaccine as one tool in a broader addiction-treatment strategy.
