Scientists preparing first human trials for vaccines that block the effects of deadly opioids
Fentanyl vaccines are heading into their first human trials, with Phase 1 testing set to begin in early 2024 at Columbia University. Developed by researchers at the University of Montana and University of Washington, the vaccines train the immune system to grab fentanyl molecules in the bloodstream, like a sponge, before they can reach the brain. That means no high, and no slowed breathing, which is what makes overdoses fatal. The team is especially focused on people in the first two years of recovery, when relapse risk is highest. If it works, this could become a powerful new tool in a crisis that has demanded every bit of compassion and ingenuity we can offer.
