New fentanyl vaccine blocks deadly overdoses before they start

Article excerpt

Scripps Research has developed an experimental vaccine that could prevent fentanyl overdoses by blocking the drug before it reaches the brain. Unlike treatments targeting fentanyl alone, this vaccine trains the immune system to recognize a broad spectrum of fentanyl-related designer drugs and their most dangerous variants. The approach represents a potential paradigm shift in overdose prevention, moving from crisis response to proactive immunological defense. If successful in human trials, the vaccine could address one of the most urgent public health crises facing the country, where synthetic opioids kill tens of thousands annually.
