Fentanyl, a synthetic opioid significantly stronger than morphine, has contributed to a large number of overdose deaths worldwide. Researchers are now exploring vaccines that train the immune system to recognize and neutralize fentanyl before it affects the brain. While still under investigation, early research suggests that anti-fentanyl vaccines may provide a new tool for preventing overdose and supporting addiction recovery. What Is a Fentanyl Vaccine? A fentanyl vaccine is an experimental immunotherapy designed to trigger the body\u2019s immune system to produce antibodies that bind&#8230;<\/p>\n","protected":false},"author":1,"featured_media":14480,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[15],"tags":[],"class_list":["post-9325","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-epidemic"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Fentanyl Vaccine: Breakthrough in Addiction Care<\/title>\n<meta name=\"description\" content=\"Fentanyl vaccine explained.
