Cohort Studies

"I feel like I should give something back to all the folks we've lost. I hope they can find something [within me] they can use to help others."
--Non-Progressor Study Participant

These studies are critical in the development of an HIV vaccine. They are observational, therefore participants will not be given any vaccines or medications.

Non-Progressor Study
This study hopes to learn more about the immune system in people who fit into one of the two groups below.

Long-Term Non-Progressors:

Participants must have:

• HIV infection for at least 12 years
• Never been on HIV medications (some exceptions allowed)
• T cell counts never below 500 (any viral load is allowed for this group)
• Never had opportunistic infection

Controllers:

Participants must have:

• HIV infection-duration for at least one year
• T cell counts never below 200
• Never been on HIV medications (some exceptions allowed)
• 3 or more viral loads less than or equal to 2000 copies/mL in the past year. Viral loads must be drawn while NOT on HIV medication
