Study Endpoints

Primary Endpoints

Geometric Mean Titers Against Influenza A Strains After Vaccination With Fluzone® Quadrivalent Influenza Vaccine or Trivalent Influenza Vaccines in All Participants
Day 28 post final vaccination

Immunogenicity outcomes were assessed in serum samples by hemagglutination inhibition (HAI) assay. The lower limit of quantitation (LLOQ) was set at the lowest dilution used in the assay, 1/10. Titers below this level were reported as \<10.

Geometric Mean Titers Against Influenza B Strains After Vaccination With Fluzone® Quadrivalent Influenza Vaccine or Trivalent Influenza Vaccines With Corresponding B Strain in All Participants
Day 28 post final vaccination

Immunogenicity outcomes were assessed in serum samples by HAI assay. The lower limit of quantitation (LLOQ) was set at the lowest dilution used in the assay, 1/10. Titers below this level were reported as \<10.

Geometric Mean Titers Against Influenza B Strains After Vaccination With Fluzone® Quadrivalent Influenza Vaccine or Trivalent Influenza Vaccines Without Corresponding B Strain in All Participants
Day 28 post final vaccination

Immunogenicity outcomes were assessed in serum samples by HAI assay. The lower limit of quantitation (LLOQ) was set at the lowest dilution used in the assay, 1/10. Titers below this level were reported as \<10.

Geometric Mean Titers Against Influenza Vaccine Antigens After Vaccination With Fluzone® Quadrivalent Influenza Vaccine or Trivalent Influenza Vaccines in Participants Aged 6 Months to Less Than 36 Months.
Day 28 post final vaccination

Immunogenicity outcomes were assessed in serum samples by HAI assay. The lower limit of quantitation (LLOQ) was set at the lowest dilution used in the assay, 1/10. Titers below this level were reported as \<10.

Geometric Mean Titers Against Influenza Vaccine Antigens After Vaccination With Fluzone® Quadrivalent Influenza Vaccine or Trivalent Influenza Vaccines in Participants Aged 3 Years to Less Than 9 Years.
Day 28 post-vaccination

Immunogenicity outcomes were assessed in serum samples by HAI assay. The lower limit of quantitation (LLOQ) was set at the lowest dilution used in the assay, 1/10. Titers below this level were reported as \<10.
