First-of-its-kind fentanyl vaccine targets overdoses before they start
Fox News
Groundbreaking fentanyl vaccine enters human clinical trials in 2026, designed to prevent deadly overdoses by blocking the dangerous drug from reaching the brain.
"They would feel no effects if they ingest fentanyl — absolutely none. And they would not overdose." "This is likely to prevent many overdoses where a patient is sedated and stops breathing as a result of fentanyl."

If approved, it would become the first treatment to prevent overdoses of fentanyl, which is the leading cause of drug overdose death, statistics show. This is different than treatments like naloxone, which reverse the effects after an overdose.
