Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate immunologic response to different types of influenza vaccine among children/adolescents/young adults 4-21 years of age. This is a randomized controlled trial (RCT), that will assess immune response in about 440 participants (about 220 per vaccine arm) pre- and post-vaccination to FluMist (live attenuated influenza vaccine given by nasal administration) and Flucelvax (egg-free cell-culture inactivated influenza vaccine).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a non-blinded, randomized controlled trial analyzing influenza vaccine immunogenicity response in children/adolescents/young adults aged 4-21 years given one of two FDA approved and licensed influenza vaccines: FluMist (live attenuated influenza vaccine by nasal administration) and Flucelvax (egg-free cell-culture inactivated influenza vaccine). This study will enroll about 440 healthy participants, about 220 per vaccine arm. Participants will be randomized in blocks of 4 using a 1:1 allocation to receive either FluMist or Flucelvax. Blood work will be conducted on all participants at baseline prior to vaccine receipt and post-vaccination at Day 7 (range 6-9 days) and Day 28 (range 21-35 days). The primary objective of the study is to determine pre- and post-serologic responses to each vaccine type.
