A Trial to Assess the Immunogenicity and Safety of the Trivalent Virosomal Influenza Vaccine, Formulation of 2012-2013, in Non-Elderly Adults and Elderly Subjects
This is an open study of the use of AdimFlu-V (2012-2013 season) vaccine in non-elderly and elderly subjects. All participates will receive one dose of vaccine (0.5 ml) by intramuscular injection into the upper arm. Safety outcomes included immediate reactions at the time of vaccination, solicited local and systemic reactions for 7 days, unsolicited adverse events for 28 days, and serious adverse events. Sera prepared from blood samples will be collected from each subject immediately prior to, and 28 days after vaccination. Anti-hemagglutinin (HA) antibody titers will be determined using the WHO hemagglutination inhibition reference technique. The central laboratory who is responsible for antibody titrations will not be aware of the background of blood samples (e.g., pre- or post-serum), it is also called observer-blinded. All participates will be followed, either by clinical visit or by telephone contact, for 8 weeks after the vaccination for safety reasons.

Conditions
- Influenza
Interventions
- AdimFlu-V
Primary outcomes
- The primary objective is to evaluate the immune response (i.e. HAI titer) in subjects after administration of influenza vaccine for 2012-2013 season. — Change from baseline for HAI titer at 21 days post immunization
Serum samples will be obtained prior to vaccination, and 3 weeks post vaccination. Serum samples will be tested for anti-hemagglutinin (HA) antibodies by hemagglutination inhibition (HAI), and assays will be performed at Adimmune Corporation designated central laboratory.
