These include HIV wasting syndrome; PJP pneumonia; cerebral toxoplasmosis; extrapulmonary cryptococcosis; progressive multifocal leukoencephalopathy; any disseminated endemic mycosis (histoplasmosis); candidiasis of the esophagus, trachea, bronchi, or lung; disseminated atypical mycobacteria; non-typhoid salmonella septicemia; extrapulmonary tuberculosis; lymphoma; and Kaposi's sarcoma. * Prior participation in any HIV-1 vaccine or anti-HIV antibody-mediated prevention trial * Receipt of any investigational agent during this pregnancy * Receipt of blood products, immunoglobulin (Ig), or immunomodulating therapy within 45 days prior to, and the day of delivery * 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 infant safety or reactogenicity, or a volunteer's ability to give informed consent * Any condition that places the newborn at higher risk of early-onset sepsis, such as concern for active maternal infection at delivery, as determined by local site investigators (eg, fever) * Detectable hepatitis B surface antigen (HBsAg) Inclusion Criteria: Infant * Born via Caesarean delivery to a pregnant woman living with HIV-1 who meets all maternal inclusion/exclusion criteria listed above * Estimated gestational age at birth is at least 37 weeks Note: If gestational age at birth is not documented in the infant's available birth records, study staff may assess gestational age at the earliest possible opportunity during the screening period and use this assessment for purposes of eligibility determination. * Weight at birth is at least 2.5 kg * Has initiated ARV prophylaxis consistent with current site-specific standard of care * Hemoglobin (HgB) more than 14.0 g/dL * White blood cell (WBC) count ≥ 7,000 cells/mm3 * Platelets more than 100,000 cells/mm3 * Alanine aminotransferase (ALT) less than 1.25 times upper limit of age-adjusted normal * Creatinine less than 1.1 times upper limit of age adjusted normal * Negative HIV-1 nucleic acid test (NAT) on specimen drawn within 72 hours of birth * Written informed consent provided by mother * Age is equal to or less than 7 days Exclusion Criteria: Infant * Any clinically significant congenital anomaly/birth defect * Documented or suspected serious medical illness, infection, clinically significant finding from physical examination, or immediate life-threatening condition, including requirement for ongoing supplemental oxygen, as judged by the examining clinician * Receipt of or anticipated need for blood products, immunoglobulin, or immunosuppressive therapy. This includes infants who require hepatitis B immunoglobulin (HBIG), but it does not require exclusion of infants who receive hepatitis B vaccine in the newborn period. * Receipt of any other investigational product
