Randomized Open-Label Trial to Compare the Immunogenicity of Cell Culture-Based and Recombinant Unadjuvanted Quadrivalent Influenza Vaccines to Conventional Egg-Based Unadjuvanted Quadrivalent Influenza Vaccines Among Healthcare Personnel Aged 18-64 Years

Centers for Disease Control and Prevention·interventional·Posted Oct 29, 2018·Updated Jul 22, 2024

In Brief

A Phase 4 clinical trial evaluating Flublok, Flucelvax, and 3 other interventions for Influenza. Completed, enrolled 944 participants across 2 sites.

Detailed Summary

This randomized, open-label trial will assess humoral and cell-mediated immune responses to cell culture-based and recombinant unadjuvanted quadrivalent influenza vaccines compared to conventional egg-based unadjuvanted quadrivalent standard dose (15µg of HA per strain) influenza vaccines among persons aged 18-64 years. The trial will be conducted at two sites in the United States during two influenza seasons (2018-19 and 2019-20). Stratified enrollment procedures will be used to enroll a mix of participants based on age.
