* A household contact who is immunocompromised; the subject should also avoid close contact with immunocompromised individuals for at least 28 days after any study vaccine dose
* Expected household contact within 28 days after each dose with a health care provider for immunocompromised subjects or who is a day care provider for infants under the age of 6 months
* History of allergic reaction to any component of the study vaccine
* Previous medical history, or evidence, of an intercurrent or chronic illness that, in the opinion of the investigator, may compromise the safety of the subject
* Known or suspected active or chronic hepatitis infection
* History of medical diagnosis of asthma, reactive airway disease, wheezing requiring medication, cystic fibrosis, bronchopulmonary dysplasia, chronic pulmonary disease, medically confirmed apnea, hospitalization for respiratory illness or mechanical ventilation for respiratory illness (excludes elective mechanical ventilation during surgery for subjects in Cohorts 1 and 2)
