About

The safety of parenterally administrated investigational vaccine (commercial influenza vaccine formulated with adjuvant Matrix M) in healthy adults (age 18-50) and healthy elderly (age 65-75), will be investigated in the study. Moreover, the study aims to study parameters associated with improved protection against clinical disease in elderly. Such parameters include HI-titres, a balanced Th1/Th2 response as well as a functional cellular immune response.

Vaccination will start in 22 healthy adults receiving the investigational vaccine. Vaccination of elderly will be initiated only after demonstration of safety in adults. 88 healthy elderly volunteers will be vaccinated, 44 will receive the seasonal influenza vaccine alone and 44 will receive the investigational vaccine. Vaccines will be administrated intramuscularly in the upper arm. One dose will be administered to each volunteer included in the study. Blood samples for basic immunological assessments of cellular and humoral immunity will be taken at day 0, 7, 28, 90 and 150.

The investigational vaccine is equal to one standard human dose of a commercial seasonal influenza vaccine to which 50 µg of adjuvant Matrix M has been added.

Volunteer has an unstable systemic disease (including active infection, uncontrolled hypertension [> 160/100], unstable angina, congestive heart failure, myocardial infarction within the previous year, serious cardiac arrhythmia requiring medication, hepatic, renal and metabolic disease)
Volunteer has recent history (within 6 months) of chronic alcohol or drug abuse of which may compromise the patient's safety or ability to participate in study activities
Volunteer has a history of psychiatric disorder that prevents patients from providing informed consent or following Protocol instructions
Volunteer is currently enrolled in an investigational device or drug trial, or < 1 month since completing an investigational device or drug trial
Female volunteers who are pregnant or lactating (only applicable for Pre-Study)
Volunteer has any other factor that in the opinion of the Investigator (or designee) would make the patient unsafe or unsuitable for the study
