A double conjugation strategy was implemented to produce an anti-fentanyl vaccine, which was predicated upon preformed-antibody-assisted antigen presentation. The new vaccine was found to reduce the psychoactive effects of fentanyl without the addition of the immunostimulant CpG oligodeoxynucleotide.

Enzyme-linked immunosorbent assay (ELISA) offers an effective, inexpensive, and reliable approach for the analysis of humoral immune responses. Here, we describe a protocol for measuring anti-fentanyl antibodies generated by the immunization of mice with novel opioid vaccine candidates. We describe steps for coating BSA-fentanyl antigen and standard wells.

Introduction: In this perspective review, we evaluated the clinical management of fatal fentanyl overdose in several routes of administration, concentrating on both legally prescribed and illegally produced formulations.
Methods: A literature search was conducted on Web of Science, PubMed, and Google Scholar databases, using the following keywords: fentanyl, illicit fentanyl, deaths, misuse, abuse, and naloxone. We included only articles whose abstracts were available in English.

Opioid use disorder - particularly involving fentanyl - has precipitated a public health crisis characterized by a significant increase in addiction and overdose-related deaths. Fentanyl-specific immunotherapy, which aims at inducing fentanyl-specific antibodies capable of binding fentanyl molecules in the bloodstream, preventing their entry in the central nervous system, is therefore gaining momentum. Conventional opioid designs rely on the covalent conjugation of fentanyl analogues to immunogenic carrier proteins that hold the inherent capacity of mounting immunodominant responses.
