About
The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of the AIDSVAX B/E vaccine and the MVA/HIV62B vaccine in healthy, HIV-1-uninfected adults who previously received MVA/HIV62B in DNA/MVA or MVA/MVA vaccine regimens in the HVTN 205 study.
Full description
This study will evaluate the safety, tolerability, and immunogenicity of the AIDSVAX B/E vaccine and the MVA/HIV62B vaccine in healthy, HIV-1-uninfected adults who previously received MVA/HIV62B in DNA/MVA or MVA/MVA vaccine regimens as part of the HVTN 205 study.
Participants in this study will be assigned to one of five groups based on their previous vaccine regimen received in HVTN 205. Depending on their group, participants will receive the MVA/HIV62B vaccine, the AIDSVAX B/E vaccine, or both the MVA/HIV62B vaccine and the AIDSVAX B/E vaccine. All participants will receive their assigned vaccines at study entry (Day 0) and Month 4. Participants will attend several study visits through Month 10. Visits will include physical examinations, blood collection, HIV testing and risk reduction counseling, and interviews and questionnaires. Optional procedures at some visits include collection of rectal fluids, cervical fluids, and semen. Study staff will contact participants 2 years following the initial study injection for follow-up health monitoring.

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:
Any medical, psychiatric, occupational, or other condition that, in the judgment of the investigator, would interfere with, or serve as a contraindication to, protocol adherence, assessment of safety or reactogenicity, or a volunteer's ability to give informed consent
Psychiatric condition that precludes compliance with the protocol. Specifically excluded are persons with psychoses within the past 3 years, ongoing risk for suicide, or history of suicide attempt or gesture within the past 3 years.
Current anti-tuberculosis (TB) prophylaxis or therapy
Asthma other than mild, well-controlled asthma. (Symptoms of asthma severity as defined in the most recent National Asthma Education and Prevention Program (NAEPP) Expert Panel report).
Diabetes mellitus type 1 or type 2, including cases controlled with diet alone. (Not excluded: history of isolated gestational diabetes.)
Thyroidectomy, or thyroid disease requiring medication during the last 12 months
Hypertension:
Bleeding disorder diagnosed by a doctor (eg, 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. Also exclude if volunteer has used medications in order to prevent or treat seizure(s) at any time within the past 3 years.
Asplenia: any condition resulting in the absence of a functional spleen
