摘要: ABSTRACTFrequent mismatches between the predominant circulating B strain lineage and in trivalent influenza vaccines have resulted missed opportunities to prevent illness. Quadrivalent containing strains from each of 2 lineages been developed for improved prevention infections. Here, we describe results a phase III, randomized, double-blind, active-controlled, multicenter trial examining safety immunogenicity split-virion inactivated quadrivalent vaccine (IIV4) 675 adults ≥ 65 y age (NCT01218646). Participants were randomly assigned 1:1:1 receive single intramuscular injection with investigational IIV4, or one (IIV3s): licensed IIV3 Victoria-lineage an Yamagata-lineage strain. Post-vaccination (day 21) hemagglutinin inhibition titers all induced by IIV4...
