Who can join

Age: 18 and older, up to 50. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• General and Demographic Criteria
• Age of 18 to 50 years
• Access to a participating HIV Vaccine Trials Network (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 and completes a questionnaire prior to first vaccination with verbal demonstration of understanding of all questionnaire items initially answered incorrectly
• Agrees not to enroll in another study of an investigational research agent before the last scheduled protocol clinic visit
• Good general health as shown by medical history, physical exam, and screening laboratory tests
• HIV-Related Criteria:
• Willingness to receive HIV test results
• Willingness to discuss HIV infection risks and amenable to HIV risk reduction counseling.
• Assessed by the clinic staff as being at "low risk" for HIV infection and committed to maintaining behavior consistent with low risk of HIV exposure through the last required protocol clinic visit. Low risk guidelines are found on the protocol web page under Study Materials on the HVTN Members' site (https://members.hvtn.org/protocols/hvtn122).
• Laboratory Inclusion Values
• Hemogram/Complete Blood Count (CBC)
• Hemoglobin greater than or equal to 11.0 g/dL for volunteers who were born female, greater than or equal to 13.0 g/dL for volunteers who were born male
• White blood cell count equal to 3,300 to 12,000 cells/mm\^3
• Total lymphocyte count greater than or equal to 800 cells/mm\^3
• Remaining differential either within institutional normal range or with site physician approval
• Platelets equal to 125,000 to 550,000/mm\^3
• Chemistry
• Chemistry panel: Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase less than 1.25 times the institutional upper limit of normal; creatinine less than or equal to institutional upper limit of normal.
• Virology
• Negative HIV-1 and -2 blood test: US volunteers must have a negative US Food and Drug Administration (FDA)-approved enzyme immunoassay (EIA).
• Negative Hepatitis B surface antigen (HBsAg)
• Negative anti-Hepatitis C virus antibodies (anti-HCV), or negative HCV polymerase chain reaction (PCR) if the anti-HCV is positive
• Urine:

You may not qualify if…

• General
• 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; or BMI greater than or equal to 35 with 2 or more of the following: age greater than 45, systolic blood pressure greater than 140 mm Hg, diastolic blood pressure greater than 90 mm Hg, current smoker, known hyperlipidemia
• 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 122 study
• Pregnant or breastfeeding
• Active duty and reserve US military personnel
• Vaccines and other Injections
• HIV vaccine(s) received in a prior HIV vaccine trial. For volunteers who have received control/placebo in an HIV vaccine trial, the HVTN 122 PSRT will determine eligibility on a case-by-case basis.
• Non-HIV experimental vaccine(s) received within the last 5 years in a prior vaccine trial. Exceptions may be made by the HVTN 122 PSRT for vaccines that have subsequently undergone licensure by the FDA. For volunteers who have received control/placebo in an experimental vaccine trial, the HVTN 122 PSRT will determine eligibility on a case-by-case basis. For volunteers who have received an experimental vaccine(s) greater than 5 years ago, eligibility for enrollment will be determined by the HVTN 122 PSRT on a case-by-case basis.
• Live attenuated vaccines other than influenza vaccine received within 30 days before or scheduled and intended to be received within 14 days after the first vaccination (eg, measles, mumps, and rubella [MMR]; oral polio vaccine [OPV]; varicella; yellow fever)
• Influenza vaccine or any vaccines that are not live attenuated vaccines and were received within 14 days prior to first vaccination (eg, tetanus, pneumococcal, Hepatitis A or B)
• Allergy treatment with antigen injections within 30 days before first vaccination or that are scheduled and intended to be received within 14 days after first vaccination
• Immune System
• Immunosuppressive medications received within 168 days before first vaccination. (Not exclusionary: [1] corticosteroid nasal spray; [2] inhaled corticosteroids; [3] topical corticosteroids for mild, uncomplicated dermatitis; or [4] a single course of prednisone or equivalent at doses less than 60 mg/day and length of therapy less than 11 days with completion at least 30 days prior to enrollment.)
• Serious adverse reactions to vaccines or to vaccine components, including history of anaphylaxis and related symptoms such as hives, respiratory difficulty, angioedema, and/or abdominal pain. (Not excluded from participation: a volunteer who had a nonanaphylactic adverse reaction to pertussis vaccine as a child.)
• Immunoglobulin received within 60 days before first vaccination
• Autoimmune disease
• Immunodeficiency
• Clinically significant medical conditions
• Untreated or incompletely treated syphilis infection
• Clinically significant medical condition, physical examination findings, clinically significant abnormal laboratory results, or past medical history with clinically significant implications for current health. A clinically significant condition or process includes but is not limited to:
• A process that would affect the immune response,
• A process that would require medication that affects the immune response,
• Any contraindication to repeated injections or blood draws,
