Randomized Controlled Trial
Immunogenicity and safety of a quadrivalent inactivated influenza virus vaccine compared with a comparator quadrivalent inactivated influenza vaccine in a pediatric population: A phase 3, randomized noninferiority study.
Seqirus 2010 Southern Hemisphere split-virion trivalent inactivated influenza vaccine (IIV3) was associated with increased febrile reactions in children. Studies in vitro concluded that increasing concentrations of splitting agent decreased residual lipids and attenuated proinflammatory cytokine signals associated with fever. We assessed immunogenicity and safety of a quadrivalent inactivated influenza vaccine (IIV4; produced using higher concentration of splitting agent) versus a United States-licensed comparator IIV4 in healthy children aged 5-17years. ⋯ Seqirus Pty Ltd; Clinicaltrials.gov identifier: NCT02545543.
