What is being measured

The primary outcome is the main question the study is designed to answer.

  1. RSV-A Neutralization Antibody Titers Expressed as Geometric Mean Titers (GMTs)

    The serum neutralization assay is a functional assay that measures the ability of serum antibodies to neutralize RSV-A entry and replication in a host cell line. The serum neutralizing antibody titer is expressed in ED60 (Estimated Dilution 60) and corresponds to the inverse of the interpolated serum dilution that yields a 60% reduction of the signal compared to a control without serum.

    Measured: At 1 month after the RSV_PreF3 OA investigational vaccine dose (at Day 31 for the Co-Ad Group and at Day 61 for the Control Group)

  2. Hemagglutinin Inhibition (HI) Antibody Titers for Each of the FLU Vaccine Strains Expressed as Group GMTs

    HI antibody titers were assessed for each of the Flu vaccine strains, namely Flu A/Hong Kong/2671/2019 (H3N2), Flu A/Victoria/2570/2019 (H1N1), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Washington/02/2019 (Victoria). The serum HI antibody titers are expressed in 1/Dilution (DIL) where DIL corresponds to the highest dilution that shows complete HI.

    Measured: 1 month after the FLU vaccine dose (at Day 31)

Secondary outcomes (12)
  1. Secondary: HI Seroconversion Status for Each of the Flu Vaccine Strains Expressed as Seroconversion Rate (SCR)

    SCR for HI antibody response was defined as the percentage of vaccinees who have either a HI pre-dose titer < 1:10 and a post-dose titer >= 1:40 or a pre-dose titer >= 1:10 and at least a four-fold increase in post-dose titer. HI antibody titers were assessed for each of the Flu vaccine strains, namely Flu A/Hong Kong/2671/2019 (H3N2), Flu A/Victoria/2570/2019 (H1N1), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Washington/02/2019 (Victoria).

    Measured: 1 month after the FLU vaccine dose (at Day 31)

  2. RSV-A Neutralization Antibody Titers Expressed as Mean Geometric Increase (MGI)

    MGI was defined as the geometric mean of the within participant ratios of the post dose titer over the pre-dose titer.

    Measured: 1 month after the RSV_PreF3 OA investigational vaccine dose (at Day 31 for the Co-Ad Group and at Day 61 for the Control Group)

  3. RSV-B Neutralization Antibody Titers Expressed as Geometric Mean Titers (GMT)

    The serum neutralization assay is a functional assay that measures the ability of serum antibodies to neutralize RSV-B entry and replication in a host cell line. The serum neutralizing antibody titer is expressed in ED60 (Estimated Dilution 60) and corresponds to the inverse of the interpolated serum dilution that yields a 60% reduction of the signal compared to a control without serum.

    Measured: 1 month after the RSV_PreF3 OA investigational vaccine dose (at Day 31 for the Co-Ad Group and at Day 61 for the Control Group)

  4. RSV-B Neutralization Antibody Titers Expressed as MGI

    MGI was defined as the geometric mean of the within participant ratios of the post-dose titer over the pre-dose titer.

    Measured: 1 month after the RSV_PreF3 OA investigational vaccine dose (at Day 31 for the Co-Ad Group and at Day 61 for the Control Group)

  5. HI Antibody Titers for Each of the FLU Vaccine Strains Expressed as GMTs

    HI antibody titers were assessed for each of the Flu vaccine strains, namely A/Hong Kong/2671/2019 (H3N2), Flu A/Victoria/2570/2019 (H1N1), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Washington/02/2019 (Victoria). The serum HI antibody titers are expressed in 1/DIL where DIL corresponds to the highest dilution that shows complete HI.

    Measured: At baseline (at Day 1) and 1 month after the FLU vaccine dose (at Day 31)

  6. HI Seroprotection Status for Each of the FLU Vaccine Strains Expressed as Seroprotection Rate (SPR)

    SPR for HI antibody response was defined as percentage of vaccinees with a serum HI titer >= 1:40 that usually is accepted as indicating protection. HI antibody titers were assessed for each of the Flu vaccine strains, namely A/Hong Kong/2671/2019 (H3N2), Flu A/Victoria/2570/2019 (H1N1), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Washington/02/2019 (Victoria).

    Measured: At baseline (at Day 1) and 1 month after the FLU vaccine dose (at Day 31)

  7. HI Antibody Titers for Each of the FLU Vaccine Strains Expressed as MGI

    MGI was defined as the geometric mean of the within participant ratios of the post-dose titer over the pre-dose titer. HI antibody were assessed for each of the FLUvaccine strain, namely A/Hong Kong/2671/2019 (H3N2), Flu A/Victoria/2570/2019 (H1N1), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Washington/02/2019 (Victoria).

    Measured: 1 month after the FLU vaccine dose (at Day 31)

  8. Percentage of Participants With Solicited Administration Site Events

    Solicited administration site adverse events(AEs) assessed were erythema, pain and swelling. Any = occurrence of the adverse event regardless of intensity grade.

    Measured: Within 4 days (the day of vaccination and 3 subsequent days) after each vaccination

  9. Percentage of Participants With Solicited Systemic Events

    Solicited systemic events assessed were arthralgia, fatigue, fever [defined as temperature equal to or above (>=) 38 degrees Celsius (C)/100.4 degrees Fahrenheit (F)], headache and myalgia. Any = occurrence of the adverse event regardless of intensity grade or relation to study vaccination.

    Measured: Within 4 days (the day of vaccination and 3 subsequent days) after each vaccination

  10. Percentage of Participants Reporting at Least One Unsolicited Adverse Event

    An unsolicited AEs is any AE reported in addition to those solicited during the clinical study and that was not included in a list of solicited events using a Participant Diary. Also, any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms is reported as an unsolicited adverse event. Unsolicited AEs include serious, non-serious AEs and potential immune-mediated diseases (pIMDs). Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.

    Measured: Within 30 days (the day of vaccination and 29 subsequent days) after each vaccination

  11. Percentage of Participants Reporting at Least One Serious Adverse Event (SAE)

    An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant. Any = occurrence of the symptom regardless of intensity grade or relationship to vaccination.

    Measured: From Day 1 up to study end (6 months after last vaccination)

  12. Percentage of Participants Reporting at Least One Potential Immune-mediated Disease (pIMD)

    pIMDs are a subset of AEs of special interest that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune etiology.

    Measured: From Day 1 up to study end (6 months after last vaccination)
