Scientists have been developing a vaccine to prevent addiction to heroin and other opioids. Sketch out a scenario for how it might work.

a) By introducing antibodies that bind to opioids in the bloodstream, preventing them from reaching the brain's receptors.
b) By targeting specific neurotransmitters involved in the addictive pathway, disrupting the reinforcement of addictive behaviors.
c) By stimulating the production of enzymes that break down opioids more rapidly in the body, reducing their potency.
