PRIMARY outcome

Timeframe: From the first administration of palivizumab to 30 days after the last administration of palivizumab, up to 44 weeks

Population: Participants enrolled via consecutive enrollment method who had a completed CRF. Participants were excluded if there was enrollment at a non-contracting institution or beyond the contracted number; duplicate enrollment; no palivizumab administration; or if palivizumab administration began outside of the investigation period.

An adverse event (AE) was defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with their treatment. Adverse events were documented on the case report form (CRF).

Participants were excluded if there was enrollment at a non-contracting institution or beyond the contracted number; duplicate enrollment; no palivizumab administration; or if palivizumab administration began outside of the investigation period.

A serious adverse event was defined as any untoward medical occurrence in a participant that the investigator believed to be causally related to the study treatment and met at least one of the following criteria: death, life-threatening, hospitalization or prolongation of hospitalization, persistent or significant disability/incapacity, or important medical event requiring medical or surgical intervention to prevent serious outcome. Serious adverse events were documented on the case report form (CRF).

PRIMARY outcome

Timeframe: From the first administration of palivizumab to 30 days after the last administration of palivizumab, up to 44 weeks

Population: Participants enrolled via consecutive enrollment method who had a completed CRF. Participants were excluded if there was enrollment at a non-contracting institution or beyond the contracted number; duplicate enrollment; no palivizumab administration; or if palivizumab administration began outside of the investigation period.

An adverse event (AE) was defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with their treatment. If a causal relationship with palivizumab was: "Related", "Causality cannot be ruled out", or "Not assessable" as determined by the investigator, it was classified as an adverse drug reaction (ADR). An AE was considered a serious adverse event (SAE) and a serious adverse drug reaction (SADR) if the severity of the AE or ADR was any one of the following, as determined by the investigator: "Death", "Life-threatening condition", "Hospitalization or prolonged hospitalization", "Persistent or significant disability", or "Other medically important condition". Information about AEs and ADRs was documented on the case report form (CRF).

Population: Participants with available data

The Lower Respiratory Tract Infection (LRI) Score ranged from 0 (well or baseline); 1 (Upper Respiratory tract Infection \[URI\]), mild); 2 (LRI); 3 (LRI, moderate); 4 (LRI, severe) to 5 (Respiratory Failure). Components of the score included respiratory rate per minute, oxygen saturation, and physical findings of LRI. LRI scores were documented on the case report form (CRF).
