(Not excluded: [1] corticosteroid nasal spray for allergic rhinitis; [2] topical corticosteroids for mild, uncomplicated dermatitis or [3] oral/parenteral corticosteroids given for non-chronic conditions not expected to recur [length of therapy 10 days or less with completion at least 30 days prior to enrollment])
• Blood products received within 120 days before first vaccination

• Live attenuated vaccines other than influenza vaccine received within 30 days before first vaccination or scheduled within 14 days after injection
• Investigational research agents received within 30 days before first vaccination
• Intent to participate in another study of an investigational research agent during the planned duration of the HVTN 080 study
• Influenza vaccine or 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, HPV)
• Allergy treatment with antigen injections within 30 days before first vaccination or that are scheduled within 14 days after first vaccination

• Clinically significant medical condition, physical examination findings, clinically significant abnormal laboratory results, or past medical history with clinically significant implications for current health.
• 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 participant's ability to give informed consent
• Serious adverse reactions to vaccines including anaphylaxis and related symptoms such as hives, respiratory difficulty, angioedema, and/or abdominal pain.
