Recombinant Quadrivalent Influenza Vaccine (RIV4) Shows Non‑Inferior Immunogenicity and Acceptable Safety in 9–17‑Year‑Olds: Results of a Phase 3 Immunobridging Study

A phase 3 immunobridging study found that a single dose of recombinant quadrivalent influenza vaccine (RIV4) induced non‑inferior HAI responses in 9–17‑year‑olds vs 18–49‑year‑olds, with a comparable safety profile and fewer solicited reactions in adolescents.
