Influenza
Conditions
Brief summary
To assess the safety of a vaccine in healthy adults prior to the release of the trivalent vaccine (FluMist).
Detailed description
The primary study objective is to assess the safety of a monovalent vaccine of a new 6:2 reassortant in healthy adults prior to the release of the trivalent vaccine (FluMist). Safety will be demonstrated by similar fever rates (oral temperature ≥101°F) in vaccine and placebo recipients.
Interventions
0.5 mL total dose volume administered intranasal by spray applicator (approximately 0.25 mL into each nostril).
Placebo mist consisting of normal allantoic fluid. 0.5 mL total dose volume administered intranasal by spray applicator (approximately 0.25 mL into each nostril).
