Eligibility
Key inclusion criteria
Inclusion criteria

1. For the preterm cohort (excluding subjects with CLD or hemodynamically significant CHD): preterm infants in their first year of life and born = 35 weeks 0 days GA eligible to receive palivizumab in accordance with national or local guidelines, including those with:

1. Uncomplicated small atrial or ventricular septal defects or patent ductus arteriosus, or
2. Aortic stenosis, pulmonic stenosis, or coarctation of the aorta alone
2. For the CLD/CHD cohort:

1. Subjects with CLD - infants in their first year of life and a diagnosis of CLD of prematurity requiring medical intervention/management (ie, supplemental oxygen, bronchodilators, or diuretics) within the 6 months prior to randomization
2. Subjects with CHD - infants in their first year of life and documented, hemodynamically significant CHD (must be unoperated or partially corrected CHD) Note: Infants with hemodynamically significant acyanotic cardiac lesions must have pulmonary hypertension (= 40 mmHg measured pressure in the pulmonary artery) or the need for daily medication to manage CHD
3. Infants who are entering their first RSV season at the time of screening
4. Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act in the USA, EU Data Privacy Directive in the EU) obtained from the subject's parent(s)/legal representative(s) prior to performing any protocol-related procedures, including screening evaluations
5. Subject's parent(s)/legal representative(s) able to understand and comply with the requirements of the protocol including follow-up and illness visits as judged by the investigator
6. Subject is available to complete the follow-up period, which will be 1 year after Season 1/ Dose 1 for subjects without CLD/CHD, or 1 year after Season 2/Dose 1 (or last replacement dose as applicable for CHD) for subjects with CLD/CHD
