Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 20 participants, 10 in the FluMist group and 10 in the placebo group, were enrolled in the study between 08Aug2005 and 31Mar2008 at 4 sites in the USA.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 20 participants were randomized in a 1:1 ratio to the FluMist or placebo group. Participants were enrolled on a staggered schedule to assess safety. Four participants were enrolled and treated in 2005, 8 in 2006, and 8 in 2007; each subset was assessed for vaccine-related serious adverse events prior to enrollment of the next subset.

Reporting Groups
  Description
Placebo Placebo intranasal mist was composed of allantoic fluid stabilized with buffer containing sucrose, potassium phosphate, and monosodium glutamate. The total volume of 0.5 mL was administered intranasally with a spray applicator (approximately 0.25 mL into each nostril).
FluMist The total volume of 0.5 mL was administered intranasally with a spray applicator (approximately 0.25 mL into each nostril). Each dose contained approximately 10^7 TCID 50 (median tissue culture infectious dose) of each of three influenza virus strains.
