Brief Summary
The purpose of this study is to evaluate immunologic response to different types of influenza vaccine among children/adolescents/young adults 4-20 years of age. This is a randomized controlled trial (RCT), that will assess immune response in 120 participants (60 per vaccine arm) pre- and post-vaccination to Flucelvax (egg-free inactivated flu shot) and Fluzone (egg-based inactivated flu shot).

Outcome Measures
Primary Outcomes (1)
Determining Seroconversion Response - Change in HI Titers From Pre- to Post Vaccination
Hemagglutination inhibition (HI) assay will be conducted to assess immunologic outcome. Seroconversion is defined as a 4-fold or higher rise in HI titer post-vaccination given a pre-vaccination HI titer of \>= 10.
Pre-vaccination (at Day 0 timepoint) and post-vaccination (at Day 21 timepoint)
Secondary Outcomes (2)
Determining Seroprotection Level at Each Time Point
Pre-vaccination (at Day 0 timepoint) and post-vaccination (at Day 21 timepoint)
Determining Geometric Mean Titers (GMTs) at Each Time Point
Pre-vaccination (at Day 0 timepoint) and post-vaccination (at Day 21 timepoint)
Study Arms (2)
Flucelvax inactivated influenza vaccine
ACTIVE COMPARATORParticipants receiving inactivated Flucelvax influenza vaccine will receive 0.5 mL given intramuscularly
Fluzone inactivated influenza vaccine
ACTIVE COMPARATORParticipants receiving inactivated Fluzone influenza vaccine will receive 0.5 mL given intramuscularly
Interventions
Participants randomized to this study influenza vaccine arm will receive Flucelvax inactivated influenza vaccine at baseline after the baseline blood draw is complete. (Provided that this vaccine is available clinically in time for the study.)
Participants randomized to this study influenza vaccine arm will receive Fluzone inactivated influenza vaccine at baseline after the baseline blood draw is complete. (Provided that this vaccine is available clinically in time for the study.)
Eligibility Criteria
You may qualify if:
- aged 4-20 years;

You may not qualify if:
- unable or unwilling to completed required study activities, including informed consent, randomization to vaccine, and bloodwork;
- has already received influenza vaccine for the current season;
- has a known immunocompromising condition or is on an immunosuppressing medication (e.g., high dose steroids \>10 days);
- is known to be pregnant;
- has a history of severe allergy to eggs or to influenza vaccine or any of its components
