Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1: 7.5 μg pandemic influenza A/H1N1 vaccine

120 subjects to receive two doses of 7.5 μg pandemic influenza A/H1N1 vaccine 21 days apart

Group Type EXPERIMENTAL

Group 2 : 15 μg pandemic influenza A/H1N1 vaccine

120 subjects to receive two doses of 15 μg pandemic influenza A/H1N1 vaccine 21 days apart

Group Type EXPERIMENTAL

Pandemic influenza A/H1N1 vaccine

Intervention Type BIOLOGICAL

Pandemic influenza A/H1N1 vaccine (PANFLU.1), 15 micrograms per dose per 0.5 millilitre. Vaccines will be administered as a single 0.5 mL intramuscular injection in the deltoid muscle of the arm (randomized in one arm) at the first dose and the other arm for the second dose

Group 3 : 7.5 μg seasonal trivalent vaccine

60 subjects to receive two doses of 7.5 μg seasonal trivalent vaccine 21 days apart

Group Type SHAM_COMPARATOR

Seasonal trivalent vaccine

Intervention Type BIOLOGICAL

Trivalent Inactivated Influenza Vaccine (ANFLU), 7.5 micrograms of each strain per dose per 0.25 millilitre. Vaccines will be administered as a single 0.25 mL intramuscular injection in the deltoid muscle of the arm (randomized in one arm) at the first dose and the other arm for the second dose
