To answer your question: yes, it does stop mortality. The general cause of death from opioid overdose is respiratory suppression when the brainstem is too “sedated” to continue sending signals to the rest of the body to breathe, so by stopping the fentanyl from entering the brain, this vaccine also blocks mortality.
Hard to do this justice without writing a full essay, but this vaccine need not be seen as an antabuse-like “restriction” on drug users. E.g. for the stereotypical* case of a user who unknowingly gets heroin cut with fentanyl, this would protect them from the fentanyl without blocking the euphoric effects of the heroin. Its most promising utility is in preventing users of other drugs from unintentional exposure to fentanyl via contaminated supply.
*(Yes, I know most street dope is Fentanyl-based these days.)
E: And to elaborate on why they might be putting emphasis on the fact it blocks the effects of fentanyl in their explanation, it might help prevent “unintended” addiction to fentanyl when users are unknowingly consuming it in conjunction with other drugs.
