Primary Outcome Measures:

Immunogenicity of MEDI-524 [ Time Frame: · Serum ELISA binding activity at each data collection visit will be summarized ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Safety and tolerability of MEDI-524 and palivizumab as measured by [ Time Frame: through Study Day 120 for patients who receive 4 doses and Study Day 150 for patients who receive 5 doses of study drug ] [ Designated as safety issue: Yes ]
Pharmacokinetics of MEDI-524 [ Time Frame: · Serum concentrations at each data collection visit will be summarized ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	150
Study Start Date:	October 2006
Study Completion Date:	June 2007
Primary Completion Date:	March 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Active Comparator Patients will receive 15 mg/kg MEDI-524 or palivizumab administered IM every 30 days for a total of 4-5 injections.	Biological: MEDI-524 Patients will receive 15 mg/kg MEDI-524 or palivizumab administered IM every 30 days for a total of 4-5 injections.

Detailed Description:

The primary objective of this study is to determine the effect on immune reactivity to MEDI-524 of monthly intramuscular (IM) doses of MEDI-524 of monthly intramuscular (IM) doses of MEDI-524 administered for a second season, in children who previously received MEDI-524 in protocol MI-CP104. The secondary objectives are to 1) describe the safety and tolerability of MEDI-524 administered for a second season; 2) describe the serum concentration of MEDI-524 administered for a second season.
