A new vaccine may be able to totally block the effects of fentanyl — potentially saving thousands of Americans from overdoses each year.

Researchers at the University of Houston, in Texas, developed a shot that was able to stop the extremely potent drug from entering the brains of rats.

Fentanyl binds to opioid receptors in areas of the brain that control pain and emotions. During an overdose, the brain is starved of oxygen, which kills off neurons.

The shot was able to block the drug from entering the brain without affecting other painkillers like morphine, meaning a vaccinated person could still be treated with other drugs if needed.

The vaccine works by stimulating T-cells in the immune system to create antibodies that bind to fentanyl in the bloodstream. These immune proteins catch the drug as it enters the body and prevents it from spreading further and causing harm. It then gets processed in the kidney and flushed from the body.

Researchers told DailyMail.com the vaccine could be used by people suffering from opioid use disorder or college students who experiment with illicit substances.

Fentanyl was developed as a painkiller to be used in hospitals but its cheap manufacturing costs and high potency has made it a favorable cutting agent for drug dealers.

Meth, cocaine and street Xanax are just some of the drugs that are being laced with fentanyl. Just 2milligrams — the equivalent of five grains of salt — of fentanyl is enough to cause an overdose.

America is currently in the midst of a fentanyl epidemic, with around 200 Americans dying from the synthetic opioid every day. To put that in context, Covid is currently responsible for around 290 deaths per day, according to most recent official data.

Houston researchers hope their vaccine could severely tide the nation’s drug overdose crises and save the lives of thousands. They are aiming to begin phase 1 human trials for the vaccine next year. (SOURCE)
