MedImmune today announced that the U.S. Food and Drug Administration (FDA) has approved FluMist? Quadrivalent (Influenza Vaccine Live, Intranasal) for prevention of influenza. The company submitted the sBLA early in the second quarter of last year. FluMist Quadrivalent is the first quadrivalent influenza vaccine approved by the FDA.
All other currently available licensed seasonal influenza vaccines are trivalent, containing three strains [two strains of type A influenza (A/H1N1 and A/H3N2) and one B lineage strain]. FluMist Quadrivalent contains four strains (two type A strains and two type B lineages) to help provide broad protection against circulating influenza A and B.
