vaccine and cocaine

Cocaine inoculations: Imagine that a vaccine that would “teach” the body’s immune system to attack cocaine molecules once they were introduced into the body could be developed. The development of such a compound raises some interesting questions about client rights to refuse treatment.

Could the courts require that a cocaine-addicted person receive such an inoculation? If they did, and there was an adverse reaction, who would be responsible—the company that made the vaccine, or the court system?
