Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria

* Healthy children 12 to 59 months of age, whose parent/guardian understands and signs the study informed consent and agrees to vaccine administration following a detailed explanation of the study
* Seropositive for RSV, defined by serum RSV neutralizing antibody titer greater than 1:40
* Person's history has been reviewed and they have undergone a physical examination indicating that s/he is in good health
* Available for the duration of the study
* Healthy children 6 to 24 months of age whose parents/guardians can understand and sign the informed consent and agree to vaccine administration following detailed explanation of the study
* Seronegative for RSV antibody, defined by serum RSV neutralizing antibody titer less than 1:40 determined within 30 days prior to inoculation
* Person's history has been reviewed and they have undergone a physical examination indicating that s/he is in good health
* Available for the duration of the study
Exclusion Criteria
* Breastfeeding

* Evidence of clinically significant neurologic, cardiac, pulmonary, hepatic, rheumatologic, autoimmune, or renal disease by history, physical examination, and/or laboratory studies, including urinalysis
* Behavioral, cognitive, or psychiatric disease that, in the opinion of the investigator, affects the ability of the person to understand and cooperate with the study protocol
* Other condition that, in the opinion of the investigator, would jeopardize the safety or rights of a participant in the study or would render the person unable to comply with the protocol
* Has had medical, occupational, or family problems as a result of alcohol or illicit drug use during the 12 months prior to study entry
* History of a severe allergic reaction or anaphylaxis
* History of splenectomy

The following are temporary or self-limiting conditions and, once resolved, the person may be enrolled, if otherwise eligible. If the period of temporary exclusion is more than 56 days for adults or more than 30 days for RSV-seronegative children, the person will need to be rescreened. If the period of temporary exclusion is more than 56 days for RSV-seropositive children, a pre-inoculation serum antibody will need to be collected.
