This study is to assess the safety of a bivalent vaccine of two new 6:2 influenza virus reassortants in healthy adults prior to the release of the trivalent vaccine (FluMist) containing them.
Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Prevention
||A Prospective, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety of a Bivalent Vaccine of New 6:2 Influenza Virus Reassortants in Healthy Adults
Primary Outcome Measures:
- The primary endpoint of this study is fever (Day 0-7) defined as oral temperature ³101°F. [ Time Frame: Day 0-7 ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Secondary endpoints of the study include other reported reactogenicity events and other adverse events that occur within seven days (Day 0-7) and fourteen days (Day 0-14) following vaccination [ Time Frame: Days 0-7; 0-14 ] [ Designated as safety issue: Yes ]
| Estimated Enrollment:
| Study Start Date:
| Study Completion Date:
Active Comparator: 1
A single dose of either bivalent vaccine or placebo mist by intranasal spray on Study Day 0.
Placebo Comparator: 2
A single dose of either bivalent vaccine or placebo mist by intranasal spray on Study Day 0
The primary study objective is to assess the safety of a bivalent vaccine of two new 6:2 influenza virus reassortants in healthy adults prior to the release of the trivalent vaccine (FluMist) containing them. Safety will be demonstrated by similar fever rates (oral temperature ≥101°F Days 0-7) in vaccine and placebo recipients.

- Participation in another investigational trial within 30 days prior to enrollment or expected enrollment in another investigational trial during this study;
- Chronic or regular use of antipyretic or analgesic medication on a daily or every other day basis; Notes: A daily dose of 81 mg of aspirin is not considered a contraindication to enrollment. Discontinuation of prophylactic use of antipyretic or analgesic medications at the time of enrollment and for fourteen days following vaccination is not considered a contraindication to enrollment.
- Pregnancy or, in biologically capable women (e.g., menses within the last year) participant does not agree to use acceptable birth control measures as determined by the investigator continuously for three months after enrolling into the study (for those biologically capable, a urine pregnancy test must be performed on the day of vaccination with a negative result);
- Breastfeeding or lactating women;
- Administration of intranasal medications within two weeks prior to enrollment or expected receipt during this study;
- Employees of the investigational site or their family member or any individuals involved with the conduct of the study; and
- Any condition that in the opinion of the investigator, might interfere with the vaccine evaluation.
