Brief Summary
This study will assess the effect of a different dose of the seasonal flu vaccine 2013-2015 on the immune response to improve the investigators understanding of cellular and humoral immune responses induced. The scope of this study is to determine the profile of cellular activation and antibody production in the ageing immune system following flu immunization. This study will enroll 100 male or female subjects ≥65 year old and 90 transplant recipients. These persons will be deemed to be " at risk " in case of influenza infection and should be vaccinated according to Swiss Federal Office of Public Health. A medical doctor from the CHUV will inform the patients about the present study and ask them whether they would be willing to participate in the study. All subjects will be distributed between the two groups according to a computer-generated randomization sequence. The randomization will be done in blocks to ensure balance across groups. The participants and site staff will not be blinded due to the different administration assignments. Group 1 subjects will receive a single dose and group 2 subjects a double dose of MUTAGRIP® manufactured by Sanofi Pasteur containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012. Vaccine immunogenicity and safety will be assessed 1, 2, 4 and 24 weeks after vaccination. Study duration per volunteer is 6 months after vaccination.

Study Arms (2)
Group 1
ACTIVE COMPARATORSingle dose of MUTAGRIP® containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012.
Group 2
EXPERIMENTALDouble dose of MUTAGRIP® (one dose into the right deltoid area and the other one into the left deltoid area) containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012.
Interventions
All subjects will receive either a single or double doses of MUTAGRIP® containing A/California/7/2009 (H1N1); A/Texas/50/2012 (H3N2); B/Massachusetts/2/2012. The double dose regimen will be administered at the same time.

Eligibility Criteria
You may qualify if:
- Age ≥65 year old.
- Able to give informed consent.
- Necessity to receive influenza seasonal vaccination in 2013-2015.
- Availability for the duration of the study and willingness to attend all scheduled visits.
- Hemoglobin value ≥100 g/l , Leukocytes ≥3.5 G/L, Platelets count ≥100 G/l at the time of screening, or determined within 8 weeks before screening in the course of regular medical examination and validated by the medical doctor.
You may not qualify if:
- Contraindication against seasonal flu vaccination.
- Use of any investigational or non-registered drug or vaccine within 30 days preceding the first dose of the study vaccine, or planned use during the study period and safety follow-up.
- Immunodeficiency or chronic administration (defined as more than 14 consecutive days) of immunosuppressive or other immune-modifying drugs within six months prior to the first vaccine dose. (For corticosteroids, this will mean prednisone, or equivalent, ≥0.5 mg/kg/day. Inhaled and topical steroids are allowed).
- Hypersensitivity to the active substances, to any of the excipients, to eggs, chicken proteins, neomycin, formaldehyde and octoxinol 9.
- Acute disease at the time of enrollment \[Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhea, mild upper respiratory infection with or without low-grade febrile illness, i.e., temperature \<38°C\].
- An unstable chronic condition (unstable chronic renal failure, unstable diabetes, unstable chronic cardiac condition, uncontrolled asthma, etc.).
- Receipt of blood-derived products (immunoglobulin; plasma) within 120 days prior to enrollment.
