comply with protocol requirements, instructions, and protocol-stated restrictions, and
the subject is likely to complete the study as planned
Minimum age
28 Days
Maximum age
36 Months
Sex

Can healthy volunteers participate?
No
Key exclusion criteria
- Use of or anticipated need for invasive mechanical ventilation, cardiopulmonary
bypass, hemodialysis, or extracorporeal membrane oxygenation; or subjects who are not
expected to survive the current illness

- Underlying immune deficiency, (e.g., from confirmed human immunodeficiency virus
infection or use of an immunosuppressive medication except immunoglobulin A
deficiency)

- Receipt of (within 12 months before Screening) or on a waiting list for a bone marrow,
stem cell, or solid organ transplant, or who received radiation or chemotherapy
(within 12 months before screening)

- Receiving chronic oxygen therapy at home before admission

- Subjects whose mother received an investigational RSV vaccination while pregnant with
the subject if they were born at term (=37 weeks of gestation) and are less than 12
months of age

- In Part 2, subjects dosed with an investigational or approved medication that is
intended to prevent or treat RSV infection within the following times before the first
