Brief Summary

The present study, randomized, single-blind, dose-ranging, multicenter study, will evaluate immunogenicity, safety and tolerability of two doses of adjuvanted and not-adjuvanted new swine-origin influenza A/H1N1 virus monovalent subunit vaccine in healthy children and adolescents. A booster dose will be administered 12 months after the first vaccination.

Conditions

Pandemic Influenza

Keywords

Pandemic influenza; Vaccine

Outcome Measures

Primary Outcomes (1)

• To identify the preferred vaccine formulation dosage (antigen & adjuvant) and schedule (one or two administrations) of the H1N1sw monovalent vaccine in children and adolescents

  43 days after first vaccination

Secondary Outcomes (1)

• To evaluate immunogenicity against A/California H1N1sw strain after booster dose of egg-derived seasonal trivalent, MF59 adjuvanted vaccine Fluad, recommended for 2010/2011 season, administered 12 months after primary course according to CHMP criteria.

  3 weeks after booster vaccination

This trial will be performed at multiple study sites in a population of healthy children and adolescent. Subjects will be randomized to receive 2 IM injections of low dose of antigen \& adjuvant, or high dose of antigen \& adjuvant, or high dose of antigen, according to the study groups.

high dose of antigen; high dose of antigen + high dose of adjuvant; low dose of antigen + low dose of adjuvant

You may not qualify if:

• Subject's parents or legal guardians who are not able to comprehend and to follow all required study procedures;
• Individuals with history or any illness that, in the opinion of the investigator, might interfere with the results of the study or pose additional risk to the subjects due to participation in the study;
• Individuals with any serious chronic or progressive disease according to judgment of the investigator;
• History of any anaphylaxis, serious vaccine reactions to any excipients and to eggs (including ovalbumin) and chicken protein;
• Individuals who have had adjuvanted influenza vaccine or documented confirmed or suspected influenza disease within 3 months prior to Day 1.

• Individuals who receive any other vaccine 4 weeks prior to enrolment in this study or who are planning to receive any vaccine within four weeks from the study vaccines; the only exception being plain seasonal influenza vaccines which are allowed until one week prior to and after one week study vaccinations;
• Individuals who have received blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation in the past 12 weeks;
• Individuals with axillary temperature ≥ 38.0 degrees Celsius within 3 days of intended study vaccination;
• Known or suspected alteration of immune function;
• History of progressive or severe neurologic disorder;
