Percentage of Participants Reporting Local Reactions After Vaccination 1: Substudy A |
Local reactions included pain at the injection site, redness and swelling and were recorded by participants in an electronic diary. Redness and swelling were measured and recorded in measuring device units, where 1 measuring device unit=0.5 centimeter (cm). Redness and swelling were graded as mild (Grade 1): greater than (>) 2.0 cm to 5.0 cm; moderate (Grade 2): >5.0 cm to 10.0 cm; severe (Grade 3): >10 cm; potentially life-threatening (Grade 4): necrosis or exfoliative dermatitis (redness) and necrosis (swelling). Pain at injection site was graded as mild (Grade 1): did not interfere with activity; moderate (Grade 2): interfered with activity; severe (Grade 3): prevented daily activity and potentially life-threatening (Grade 4): emergency room visit or hospitalization for severe pain. Grade 4 reactions were classified by the investigator or medically qualified person. Exact 2-sided confidence interval was based on the Clopper and Pearson method. |

Percentage of participants achieving seroconversion for each strain at 4 weeks after vaccination 1 and exact 2-sided 95% CI based on the Clopper and Pearson method is presented in the descriptive section. Difference in percentage of participants achieving HAI seroconversion for each strain at 4 weeks after vaccination 1 is presented in the statistical analysis section. |

HAI GMTs Before Vaccination 1 and 2 and at 1, 4, and 8 Weeks After the Last Vaccination (Participants Aged 65-85): Expanded Enrollment: Substudy B |
GMTs and 2-sided 95% CIs were calculated by exponentiating the mean logarithm of the concentrations and the corresponding CIs (based on the Student t distribution). Assay results below the LLOQ were set to 0.5*LLOQ. |

HAI GMFR From Before Vaccination 2 to 1, 4, and 8 Weeks After the Last Vaccination (Participants Aged 65-85 Years): Expanded Enrollment: Substudy B |
GMFRs and the corresponding 2-sided 95% CIs were calculated by exponentiating the mean logarithm of the fold rises and the corresponding CIs (based on the Student t distribution). Assay results below the LLOQ were set to 0.5* LLOQ. When prevaccination assay results were lower than the LLOQ and the postvaccination results were greater than or equal to the LLOQ, the prevaccination assay results were set to LLOQ for the GMFR calculation. |
