Can hiv survive in air tight medication vials, especially botox vials, if vial is shared and contaminated? last patient before me was around 15hours

Probably no risk: If the Botox vial was accessed only by a health professional with a previously unused needle, there is no risk and no worry. Nobody ever gets HIV by this kind of event in a medical office. But of course no person treating him- or herself should ever use drugs or vials previously used by anyone else; if a used, HIV contaminated needle penetrated the vial, HIV could be a risk.
