Influenza Clinical Trial
Official title:
Evaluation of the Safety, Reactogenicity and Immunogenicity of Flublok Quadrivalent (Quadrivalent Recombinant Influenza Vaccine,Seasonal Formulation) Administered Intramuscularly to Healthy Children and Adolescents Age 6-17 Years
Flublok was studied previously in children 6 -59 months of age and demonstrated less than satisfactory immunogenicity results, especially in the 6-36 month age group. Thus, the initial introduction of Flublok Quadrivalent Formulation (RIV4) into the pediatric population will evaluate immunogenicity and safety older children and adolescents, aged 6-17. This clinical trial is designed to demonstrate safety and non-inferior immunogenicity of Flublok-Q in pediatric subjects 6-17 years of age as compared to IIV4. Positive results in this study may support further studies in younger children.
The U.S. Advisory Committee on Immunization Practices (ACIP) recommends that all people ≥6 months of age receive influenza vaccine annually. Recommendations for influenza immunization of children vary somewhat among countries in the European Union, but immunization of children at high risk for complications of influenza infection is recommended by WHO and according to criteria in most countries. Currently, the immunization practices are progressing to quadrivalent formulations of inactivated influenza vaccines (IIV4) which are approved in the US for most of the indicated population. Additionally, live attenuated vaccine (LAIV4) is approved in the U.S. for individuals aged 2-49 years and Flublok®(RIV3), a purified trivalent recombinant hemagglutinin protein vaccine is approved in the U.S. for adults 18-49 years of age. Children are at particular risk of complications of influenza, including the B lineages, so expansion of the Flublok indication into the pediatric age group with a quadrivalent formulation is warranted. ;
