For volunteers who have received control/placebo in an HIV vaccine trial, the HVTN 115 PSRT will determine eligibility on a case-by-case basis. - Previous receipt of monoclonal antibodies (mAbs), whether licensed or investigational; the HVTN 115 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 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 115 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 115 PSRT on a case-by-case basis. - Live attenuated vaccines received within 30 days before first vaccination or scheduled within 14 days after injection (e.g., measles, mumps, and rubella [MMR]; oral polio vaccine [OPV]; varicella; yellow fever; live attenuated influenza vaccine) - Any vaccines that are not live attenuated vaccines and were received within 14 days prior to first vaccination (e.g., tetanus, pneumococcal, Hepatitis A or B) - Allergy treatment with antigen injections within 30 days before first vaccination or that are scheduled within 14 days after first vaccination Immune System: - Immunosuppressive medications received within 168 days before first vaccination.

For these volunteers, blood pressure must be less than or equal to 140 mm Hg systolic and less than or equal to 90 mm Hg diastolic at enrollment. - If a person has NOT been found to have elevated blood pressure or hypertension during screening or previously, exclude for systolic blood pressure greater than or equal to 150 mm Hg at enrollment or diastolic blood pressure greater than or equal to 100 mm Hg at enrollment. - Bleeding disorder diagnosed by a doctor (e.g., factor deficiency, coagulopathy, or platelet disorder requiring special precautions) - Malignancy (Not excluded from participation: Volunteer who has had malignancy excised surgically and who, in the investigator's estimation, has a reasonable assurance of sustained cure, or who is unlikely to experience recurrence of malignancy during the period of the study) - Seizure disorder: History of seizure(s) within past 3 years.
