NCT03614975

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 COMPARATOR

Participants receiving inactivated Flucelvax influenza vaccine will receive 0.5 mL given intramuscularly

Biological: Flucelvax inactivated influenza vaccine

Fluzone inactivated influenza vaccine

ACTIVE COMPARATOR

Participants receiving inactivated Fluzone influenza vaccine will receive 0.5 mL given intramuscularly

Biological: Fluzone inactivated influenza vaccine

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.)

Flucelvax inactivated influenza vaccine

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.)
