Vaccines and other Injections
6. HIV vaccine(s) received in a prior HIV vaccine trial. For volunteers who have received control/placebo in an HIV vaccine trial, the HVTN 107 PSRT will determine eligibility on a case-by-case basis.
7. 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 in a volunteer's country of residence. For volunteers who have received control/placebo in an experimental vaccine trial, the HVTN 107 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 107 PSRT on a case-by-case basis.
8. Live attenuated vaccines other than influenza vaccine received within 30 days before first vaccination or scheduled within 14 days after injection (eg, measles, mumps, and rubella \[MMR\]; oral polio vaccine \[OPV\]; varicella; yellow fever)

* Any contraindication to repeated injections or blood draws,
* A condition that requires active medical intervention or monitoring to avert grave danger to the volunteer's health or well-being during the study period,
* A condition or process for which signs or symptoms could be confused with reactions to vaccine, or

Well-controlled blood pressure is defined as consistently ≤ 140 mm Hg systolic and ≤ 90 mm Hg diastolic, with or without medication, with only isolated, brief instances of higher readings, which must be ≤ 150 mm Hg systolic and ≤ 100 mm Hg diastolic. For these volunteers, blood pressure must be ≤ 140 mm Hg systolic and ≤ 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 ≥ 150 mm Hg at enrollment or diastolic blood pressure ≥ 100 mm Hg at enrollment.
