Outcome Measures

Primary Outcomes (3)

  • Percentage of Participants Who Achieved Seroconversion or Significant Increase in Single Radial Hemolysis (SRH) Area Against Each of Three Vaccine Strains After One Vaccination of FLUAD

    Immunogenicity was measured as the percentage of participants who achieved seroconversion or significant increase in single radial hemolysis (SRH) area, against each of the three vaccine strains, three weeks after vaccination (day 22), evaluated using SRH assay. Seroconversion: proportion of participants with negative pre-vaccination serum and a post-vaccination serum area ≥ 25 mm2. Significant increase: proportion of participants with at least a 50% increase in area from positive pre-vaccination serum. Seroconversion or significant increase: proportion of participants with either seroconversion or significant increase. The European (Committee for Medicinal Products for Human Use \[CHMP\]) criterion is met, if percentage of participants achieving seroconversion or significant increase in SRH area is 30% (≥65 years).

    day 22

  • Geometric Mean Ratio of Participants Against Each of the Three Vaccine Strains After One Vaccination of FLUAD

    Geometric mean ratio (GMR) of participants was calculated as the ratio of post-vaccination to pre-vaccination SRH geometric mean areas (GMAs), directed against each of the three vaccine strains, three weeks after FLUAD vaccination (day 22). The CHMP criterion was met if the geometric mean increase (GMR, day 22/day 1) in SRH antibody area is \>2.0 (≥65 years).

    day 22

  • Percentage of Participants Who Achieved SRH Area ≥25mm2 Against Each of the Three Vaccine Strains After One Vaccination of FLUAD

    Immunogenicity was measured as the percentage of participants achieving SRH area ≥25 mm2 against each of the three vaccine strains at baseline (day 1) and three weeks after FLUAD vaccination (day 22). This criterion is met according to CHMP guideline if percentage of participants achieving SRH area ≥25 mm2 is 60% (≥65 years).

    day 22

Secondary Outcomes (1)

  • Number of Participants Who Reported Solicited Local and Systemic Reactions

    1 to 4 days post-vaccination

Study Arms (1)

Sub unit, Inactivated, MF59C.1 Adjuvanted Influenza Vaccine

OTHER

No comparator is administered, only one IM single dose of trivalent subunit inactivated influenza vaccine is administered during the vaccination visit

Biological: Seasonal Influenza Vaccine

Interventions

This phase II is performed as a multicenter study in elderly subjects. Enrolled subjects received one single IM dose of trivalent subunit inactivated adjuvanted flu vaccine during the vaccination visit, according to the study protocol (follow-up period: until day 22) .

Sub unit, Inactivated, MF59C.1 Adjuvanted Influenza Vaccine

Eligibility Criteria

  • Individuals participating in any clinical trial with another investigational product 4 weeks prior to first study visit or intent to participate in another clinical study at any time during the conduct of this study.
  • Individuals who received any other vaccines within 4 weeks prior to enrollment in this study or who are planning to receive any vaccine within 4 weeks from the study vaccines.
  • Individuals who are part of study personnel or close family members conducting this study.
  • BMI \> 35 kg/m2.
