Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Children who received at least 3 doses of motavizumab in Study MI-CP104 during the 2004-2005 RSV season were eligible for enrollment in this study. It was anticipated that approximately 150 children would be enrolled.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Motavizumab or palivizumab was administered to children, using a 1:1 randomization, at 15 mg/kg of study drug by IM injection every 30 days, for a total of 4-5 doses (determined by when in the RSV season a child was enrolled) during the 2005-2006 RSV season.

Reporting Groups
  Description
Motavizumab (MEDI-524) 15 mg/kg A single intramuscular injection every 30 days for a total of 4-5 injections determined by when in the RSV season a child was enrolled.
Palivizumab 15 mg/kg A single intramuscular injection every 30 days for a total of 4-5 injections determined by when in the RSV season a child was enrolled.
