Brief Summary
Background: \- Vaccines create resistance to disease. This study tests experimental human immunodeficiency virus (HIV) vaccines that use an adenovirus as a transporter. Transporters may help vaccines stimulate an immune response against HIV. This means the body works to fight infection. Researchers want to see if different ways of giving the vaccines cause different immune responses. They also want to see if the vaccines adenovirus is contagious. Adenoviruses cause cold symptoms or mild eye infections. Participants cannot get HIV from these vaccines. But they can get the adenovirus, so their entire household and intimate contacts must participate. Objective: \- To test the safety of experimental HIV vaccines. Eligibility: \- Healthy adults 18-49 years old. Design:
- Participants will be screened with medical history, physical exam, and blood and urine tests.
- Participants will receive the vaccine 3 times over 6 months. Each time, they will have a physical exam and blood and urine tests. Samples will be taken from their nose, rectum, and cervix.
- Some participants will receive the vaccine by swallowing 11 capsules with water. Clinic staff will observe them for 1 hour.
- Some participants will receive the vaccine swabbed in their throat. They will get dose 1 at the hospital and stay there for 1 week. They will have medical tests and nose swabs. Doses 2 and 3 will not require a hospital stay.
- Participants will have 7 follow-up visits over 6 months, with a physical exam and blood tests. Samples will be taken from their nose, throat, and rectum.
- Household and intimate contacts will have 4 clinic visits over 8 months, with a physical exam and blood tests.

Eligibility Criteria
You may qualify if:
- All participants (vaccinees, household contacts, and intimate contacts) must meet all of the following criteria:
- Age 18 to 49 years for vaccinees. Age 18 to 65 years for household and intimate contacts.
- Negative FDA-approved HIV test.
- Able to provide proof of identity to the acceptance of the Principal Investigator or designee during enrollment.
- Available and willing to participate in follow-up visits and tests for the duration of the study.
- Willing to have samples stored for future research.
- In good general health without clinically significant medical history.
- Willing to discuss HIV infection risks with the study clinicians, assessed as low risk for HIV infection, amenable to HIV risk reduction counseling, and committed to maintaining behavior consistent with
- low risk of HIV exposure through the last required clinic visit in the protocol schedule.
- Negative Beta-HCG pregnancy test for females presumed to be of reproductive potential.
- A female must meet one of the following criteria:
- No reproductive potential because of menopause (one year without menses) or because of a hysterectomy, bilateral oophorectomy, or tubal ligation.
- Participant agrees to be heterosexually inactive or consistently practice contraception at least 21 days prior to and 28 days following each vaccination. Acceptable methods of contraception include the following:
- condoms, male or female, with a spermicide.
- diaphragm or cervical cap with spermicide.
- +21 more criteria
You may not qualify if:
- A participant (vaccinees, household contacts, and intimate contacts) will be excluded if they have the following:
- \. Any condition that, in the investigator s judgement, places the subject at undue risk by participating in the study.
- History of any prior disease or therapy which would affect immune or pulmonary function.
- Prior malignancy, except curatively-treated basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
- History of radiation therapy or cytotoxic/cancer chemotherapy.
- History of diabetes mellitus.
- Immunodeficiency or autoimmune disease.
- Acute infection or a recent (within 6 months) history of chronic infection suggestive of immunodeficiency.
- Taking any medication which may affect immune function, except participants may be taking low doses of nonprescription strength NSAIDS (including e.g. ibuprofen or aspirin) or acetaminophen.
- Chronic respiratory disorders including asthma, emphysema, interstitial lung disease, pulmonary hypertension, recurrent pneumonia, or recent or ongoing respiratory tract infection. If a respiratory disorder is transient, defer immunization but do not exclude the participant.
- Active Hepatitis B or C infection (i.e. Hepatitis B or C positive serology with the presence of virus antigen or DNA. Ongoing viral replication will be confirmed by a Hepatitis B antigen or Hepatitis C viral load).
- Female of child-bearing potential who is breast-feeding or planning pregnancy during the 28 days following vaccination.
- Any medical, psychiatric, or social condition, or occupational or other responsibility that, in the judgment of the investigator, would interfere with or serve as a contraindication to receipt of live virus vaccine, protocol adherence, or a participant s ability to give informed consent.
- Psychiatric condition that precludes compliance with the protocol; past or present psychoses; past or present bipolar disorder requiring therapy that has not been well controlled on medication for the past two years; disorder requiring lithium; or suicidal ideation occurring within five years prior to enrollment.
- Participants that live in the same house or apartment with any of the following will be excluded:
- +16 more criteria
