E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the humoral response (anti-haemagglutinin [HA] antibodies tested by Haemagglutination Inhibition [HI]) against each vaccine strain in adults 18-60 years and >60 years of age, 21 days after vaccination with Fluarix/Influsplit SSW 2012/2013. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the humoral response (anti-HA antibodies tested by HI) against each vaccine strain, 21 days after vaccination, in adults >60 years of age who have not and who have received an influenza vaccine in the 2011-2012 season.
To describe the reactogenicity and safety of Fluarix/Influsplit SSW 2012/2013 in adults 18-60 years and >60 years of age, in terms of solicited adverse events (AEs), unsolicited AEs and serious adverse events (SAEs).

Written informed consent obtained from the subject.
Healthy subjects or subjects with well-controlled chronic diseases as established by medical history and clinical examination before entering the study.
Female subjects of non-childbearing potential may be enrolled in the study.
Female subjects of childbearing potential may be enrolled in the study, if the subject:
has practiced adequate contraception for 30 days prior to vaccination, and

Acute, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
Chronic underlying disease, not stabilized or clinically serious.
History of chronic alcohol consumption and/or drug abuse.
Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
History of Guillain-Barré syndrome.
History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
Anaphylaxis following the administration of vaccine(s).
Pregnant or lactating female.
Female planning to become pregnant or planning to discontinue contraceptive precautions.
Any condition which, in the opinion of the investigator, prevents the subject from participating in the study.

E.5 End points |
E.5.1 | Primary end point(s) |
Humoral immune response in terms of anti-HA antibodies against each of the three vaccine influenza strains.
Geometric mean titres (GMTs) of anti-HA antibody titres.
Seroprotection rates* (SPR).
Seroconversion rates** (SCR).
Mean geometric increase*** ([MGI] also known as the seroconversion factor [SCF]).
Seroprotection power**** (SPP).
*SPR: The percentage of vaccinees with serum HI titre ≥ 1:40; usually accepted as indicating protection.
**SCR: The percentage of vaccinees with either a pre-vaccination titre < 1:10 and a post-vaccination titre ≥ 1:40 or a pre-vaccination titre ≥ 1:10 and at least 4-fold increase in post-vaccination titre.
***MGI: The fold increase in serum HI geometric mean titres post-vaccination compared to Day 0.
****SPP: The percentage of subjects who have a pre-vaccination titre < 1:40 and a post-vaccination titre ≥ 1:40. |
