Brief Summary:
This prospective annual release study is designed to evaluate the safety of 2 new influenza virus vaccine strains to be included in FluMist Quadrivalent for the 2018-2019 influenza season.

Condition or disease Intervention/treatment Phase
Influenza Healthy Biological: Bivalent influenza vaccine Other: Placebo Phase 4

Detailed Description:
This prospective. randomized, double-blind. placebo-controlled release study will enroll approximately 300 healthy adults 18 to 49 years of age (not yet reached their 50th birthday). Eligible subjects will be randomly assigned in a 4:1 fashion to receive a single dose of bivalent vaccine or placebo by intranasal spray. Randomization will be stratified by site. This study will be conducted at 2 sites in the United States of America. Each subject will receive 1 dose of investigational product on Day 1. The duration of study participation for each subject is the time from study vaccination through 180 days after study vaccination.

Arm Intervention/treatment
Experimental: Bivalent influenza vaccine
A single dose of bivalent vaccine (10^7±5 fluorescent focus unit of 2 cold-adapted, attenuated, temperature-sensitive, 6:2 reassortant influenza strain) will be administered as intranasal spray on Day 1
Biological: Bivalent influenza vaccine
A single dose of bivalent vaccine (10^7±5 fluorescent focus unit of 2 cold-adapted, attenuated, temperature-sensitive, 6:2 reassortant influenza strain) will be administered as intranasal spray on Day 1.

Placebo Comparator: Placebo
A single dose of placebo matched to bivalent influenza vaccine will be administered as intranasal spray on Day 1.
Other: Placebo
A single dose of placebo matched to bivalent influenza vaccine will be administered as intranasal spray on Day 1.




Primary Outcome Measures :
  1. Percentage of Participants Reporting Fever (Oral Temperature >= 101 Degrees Fahrenheit) Through Day 8 [ Time Frame: Day 1 through Day 8 ]
    Percentage of participants with fever (oral temperature >= 101 degrees Fahrenheit) through Day 8 is reported.


Secondary Outcome Measures :
  1. Number of Participants With Solicited Symptoms Through Day 8 [ Time Frame: Day 1 through Day 8 ]
    For this study, solicited symptoms included oral fever (> 100 degrees Fahrenheit), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity (tiredness), and headache.

  2. Number of Participants With Solicited Symptoms Through Day 15 [ Time Frame: Day 1 through Day 15 ]
    For this study, solicited symptoms included oral fever (> 100 degrees Fahrenheit), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity (tiredness), and headache.

  3. Number of Participants With Treatment-emergent Adverse Events (TEAEs) Through Day 8 and Day 15 [ Time Frame: Day 1 through Day 8; Day 1 through Day 15 ]
    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.

  4. Number of Participants With Treatment-emergent Serious Adverse Events (TESAEs) Through Day 29 and Day 181 [ Time Frame: Day 1 through Day 29; Day 1 through Day 181 ]
    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.

  5. Number of Participants With New Onset Chronic Diseases (NOCDs) Through Day 29 and Day 181 [ Time Frame: Day 1 through Day 29; Day 1 through Day 181 ]
    An NOCD is a newly diagnosed medical condition that is of a chronic, ongoing nature and is assessed by the investigator as medically significant.
