Brief Summary
The purpose of this research is to evaluate blood samples from HIV infected and non-HIV infected people opioid and non opioid users to understand how opioid affect the immune responses (body defenses against infection) to the flu vaccine.

Eligibility Criteria
You may qualify if:
- For Opioid (OP) users/non-users:
- OP users - prescribed opioids for at least the past 90 days; or injecting opioids for at least 90 days
- Opioid never-users in the past year
- Additional criteria for OP users:
- OP use for 90 days pre-flu vaccination
- Continued OP use for 4 weeks post flu vaccination
- For HIV positive participants:
- \) HIV infection, as documented by any licensed ELISA kit and confirmed by Western blot at any time prior to study entry. Participants on ART as a result of prior HIV documented infection will not be required to provide proof of diagnosis of HIV infection.
- Additional criteria for HIV positive participants:
- On ART for at least 1 year with plasma pending viral load (VL) \<200 copies/mL. Occasional viral blips up to 1000 copies/ml also acceptable provided the patients are on continuing treatment
- CD4 count available in the prior 6 months and \>200/mm3
- Undetectable viral load (\< 200 copies/mL)
- For HIV negative participants:
- \) Documented negative HIV test, either by any licensed ELISA or rapid tests within the past 6 months.
- For all participants:
- +8 more criteria
You may not qualify if:
- Contraindication to receive influenza vaccination (allergy to chicken eggs or to any other substance of the vaccine).
- Non-adherence to ART for HIV+
- Unable to provide informed consent.
- Other comorbid conditions such as diabetes mellitus type 2 (DMT2)
- Influenza vaccination already given during the current vaccination season.
