Outcome Measures

Primary Outcomes (1)

  • GMT of the haemagglutination-inhibiting (HI) antibodies and calculation of seroconversion factor, seroconversion rate & seroprotection rate, checked against CHMP criteria (for 18 - 60 years old); seroprotection power is also calculated.

    On Day 21 (+- 2) after the second vaccination

Secondary Outcomes (4)

  • Descriptive comparison of the occurrence and severity of solicited local and general symptoms

    Within 4 days after each vaccination

  • Descriptive comparison of the occurrence, severity and relationship to vaccination of unsolicited signs and symptoms

    Within 30 days after each vaccination

  • Descriptive comparison of the occurrence, severity and relationship to vaccination of serious adverse events (SAEs).

    Throughout the study

  • GMT of the HI antibodies in each case against the 3 influenza virus strains of the vaccine separately for both age groups.

    On Day 21 (+- 2), Month 3 and Month 6 after the second vaccination
