The recent fentanyl vaccine article on Ars (originally from wired.com) got me interested in wondering about the ethics of such a vaccine, its use, and how it is likely to be used in the real world. Assuming it works as advertised on fentanyl and fentanyl-derivatives without targeting other opioids or having other side effects, I wonder how people think it should (and will) be used in the United States of America.
My main concern (beyond general safety) is articulated in some of the responses in this set of interviews of 74 volunteers that were "adolescents and young adults with a diagnosed opioid use disorder (from Boston Children’s [Adolescent Substance Use and Addiction Program]), their families, experts in substance use treatment, clinicians, scientists, and the general public":
Another big concern raised in the comments on the article were the effects of the vaccination on pain management using hospitals - with numerous posts on being stuck unable to communicate while still in pain during an emergency operation. I wish the conference had included a bit more discussion on these issues, as I didn't find this very detailed beyond a general "it's complex and we're thinking about it" (which I imagine it is but is not helpful for a lay person considering the issue):

I understand the sentiment. And I'm usually in favor of broad vaccination requirements for diseases. But I worry that in this case, a vaccine would be forced on a broad population that is not at risk of encountering fentanyl. My second worry is that it will be forced on those at risk through coercion: as part of drug treatment programs or avoiding/reducing sentences in the justice system. Or, as put in a two-day conference discussing concerns with a fentanyl vaccine, "the ethical challenges to trialing a vaccine to prevent overdose, the need for protections from coercion, and the importance of autonomy and the right to make ‘bad’ choices."“Parents who had lost kids to overdose were especially enthusiastic, saying ‘Every kid should get this’ or ‘Every kid going to college should get this,’” says Weitzman.

That conference had other concerns as well: evidence of systemic racism in the availability of naloxone point to concerns about equitable access to a vaccine:Drs. Joe Kossowsky, PhD, MMSc (Boston Children’s Hospital, Harvard Medical School) and Sharon Reif, PhD (Brandeis University) shared perspectives on the complexities of fentanyl vaccination given widespread use of fentanyl as an analgesic and the overlap between several risk factors for substance use disorder and overdose and value of fentanyl for pain management. Subtle tradeoffs and operational complexities were discussed including those related to characteristics of fentanyl that make it a first line analgesic for surgical, emergency and military/battlefield uses. Many of the populations that might benefit from fentanyl as an analgesic for emergency and military purposes are paradoxically at high risk of overdose given potential for post-traumatic stress disorder [51], substance use/addiction [52,53], and pain [54].
Broader issues of addiction treatment in America:From 2019 to 2020, Black individuals had the highest rate of increase of fatal overdose (44 %) [23] and lowest rates of naloxone access and training compared to other racial and ethnic groups [24]. Intersectional stigmas resulting from systemic racism and biases against substance use drives racial inequities in treatment and outcomes of substance use [25,26].
Dr. Margarita Alegria, PhD (Massachusetts General Hospital) described disparities and fragmentation of the substance use treatment system. She advised following a public health approach for promoting and distributing a fentanyl vaccine to avoid perpetuating and exacerbating disparities, and to ensure equitable access. Moreover, she emphasized the importance of a comprehensive approach to preventing overdose in which a vaccine would comprise a component within a broad set of initiatives and services.
The participants considered whether the human papillomavirus (HPV) vaccine is analogous in treating/preventing the outcome of behaviors that may have stigma attached from various social groups:Barriers to substance use treatment persist for individuals with co-occurring mental health disorders [31], in rural areas [32], holding marginalized identities [23,33], and with inadequate insurance coverage [34], exacerbate disparities in overdose rates and substance use harms.
They also looked at lessons from the COVID vaccination efforts and discussed the importance of crafting an appropriate message for a fentanyl vaccine (which I think has also been applied to some of the recent measles outbreaks, to varying levels of effectiveness):Parallels between the HPV and fentanyl vaccines were outlined, including for example, potential for opposition stemming from concerns that vaccination could inadvertently increase risk behaviors (e.g., sexual activity among youth for the HPV vaccine, and substance use for a fentanyl vaccine). Lessons can be learned from the successes and weaknesses of HPV vaccine promotion efforts, which were strengthened by educating the public about the relationship between HPV and cervical cancer [46], but vaccination was nonetheless stigmatized and faced related hurdles [47].
For better or worse, it looks like the United States of America is very interested in developing a fentanyl vaccine to combat overdoses. In 2022 (even with the concerns about vaccines), Governor Abbott of Texas was excited about such a vaccine back in 2022:They noted that decision-making around vaccination is weighted toward emotional rather than rational decision-making, underscoring the value of narrative and storytelling for promoting adoption. Relatedly, they echoed comments on the influence of local connections and ties in fostering trust in the messages of experts. Use of tailored and targeted messaging is likely to be needed for advancing acceptance of a fentanyl vaccine demographic and geographic variation in risk factors for overdose and norms related to vaccination. Established strategies to confront vaccine hesitancy involve using personal narratives within public and patient education to help persons who might benefit from a fentanyl vaccine understand the issues involved in vaccine acceptance [44], an approach demonstrated with COVID-19 vaccines [45].
So I am interested in the thoughts of the forum-goers here: do you think a vaccine is likely to be approved? How widely will/should it be used? Any other concerns or am I just being overly worried?"Fentanyl remains the single deadliest drug threat our state and nation has ever encountered, and Texas continues leading the fight against this clandestine killer," said Governor Abbott. "I am proud to be at the University of Houston today to celebrate the brilliant achievement of Dr. Colin Haile and his research team on creating a fentanyl vaccine. This incredible, groundbreaking new therapy has the potential to revolutionize how we combat fentanyl deaths in our communities and end the afflictions of addiction that burden so many innocent Texans and Americans across the country. I look forward to working alongside the University of Houston and Dr. Haile in Texas' continued efforts to save innocent lives from being lost to this deadly drug."
