Summary:

      This is a Phase 3b, multicenter, randomized, double-blind, parallel group, placebo-controlled
      study designed to investigate the potential effect of tezepelumab (210 mg subcutaneous [SC]
      every 4 weeks [Q4W]) on antibody responses following seasonal quadrivalent influenza virus
      vaccination in the fall/winter 2021-2022 in the USA.
