Study Summary

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).

Primary Outcome

Rows in data tables represent different influenza antigens measured in 2019. Hemagglutination inhibition (HI) assay was 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 and a final HI titer of \>=40.

Interventions

  • BIOLOGICAL FluMist live attenuated influenza vaccine
  • BIOLOGICAL Flucelvax inactivated influenza vaccine
