  • Age of 18 to 50 years
  • Access to a participating HVTN Clinical Research Site (CRS) and willingness to be followed for the planned duration of the study
  • Ability and willingness to provide informed consent
  • Assessment of understanding: volunteer demonstrates understanding of this study; completes a questionnaire prior to first vaccination with verbal demonstration of understanding of all questionnaire items answered incorrectly
  • Willing to be contacted after completion of scheduled clinic visits for a total of 2 years following initial study injection
  • Agrees not to enroll in another study of an investigational research agent while in this study
  • Good general health as shown by medical history, physical exam, and screening laboratory tests
  • HIV-Related Criteria:

  • Hemogram/Complete blood count (CBC)
  • Hemoglobin greater than or equal to 11.0 g/dL for volunteers who were assigned female sex at birth, greater than or equal to 13.0 g/dL for volunteers who were assigned male sex at birth. For transgender participants who have been on hormone therapy for more than 6 consecutive months, determine hemoglobin eligibility based on the gender with which they identify (ie, a transgender female who has been on hormone therapy for more than 6 consecutive months should be assessed for eligibility using the hemoglobin parameters for persons assigned female sex at birth).
  • White blood cell count equal to 2,500 to 12,000 cells/mm\^3 with normal differential, or differential approved by Investigator of Record (IoR) as not clinically significant
  • +25 more criteria

You may not qualify if:

  • Blood products received within 120 days before first vaccination.
  • Investigational research agents received within 30 days before first vaccination.
  • Body mass index (BMI) greater than or equal to 40.
  • Volunteer has 2 or more of the following cardiac risk factors:
  • Participant report of history of elevated blood cholesterol defined as fasting low-density lipoprotein (LDL) greater than 160 mg/dL;
  • First degree relative (eg, mother, father, brother, or sister) who had coronary artery disease before the age of 50 years;
  • Current smoker; or
  • BMI greater than or equal to 35.
  • Intent to participate in another study of an investigational research agent or any other study that requires non-HVTN HIV antibody testing during the planned duration of the HVTN 132 study.
  • Pregnant or breastfeeding.
  • Active duty and reserve US military personnel.
  • Vaccines and other Injections
  • Smallpox vaccine received within the last 5 years.
  • HIV vaccine(s) received in a prior HIV vaccine trial. For volunteers who have received control/placebo in an HIV vaccine trial, the HVTN 132 PSRT will determine eligibility on a case-by-case basis.
  • Non-HIV experimental vaccine(s) received within the last 1 year in a prior vaccine trial. Exceptions may be made by the HVTN 132 PSRT for vaccines that have subsequently undergone licensure by the FDA or by the national regulatory authority where the volunteer is enrolling. For volunteers who have received control/placebo in an experimental vaccine trial, the HVTN 132 PSRT will determine eligibility on a case-by-case basis. For volunteers who have received an experimental vaccine(s) greater than 1 year ago, eligibility for enrollment will be determined by the HVTN 132 PSRT on a case-by-case basis.
