3. Available for all the visits scheduled in the study
4. Willingness to complete all study procedures
1. History of any vaccine against novel influenza A strain H1N1 (based on verbal confirmation from parent/guardian)
2. Previous laboratory confirmed case of novel influenza A strain H1N1 or treatment with oseltamivir or zanamivir for novel influenza A strain H1N1 (n.b. a child commenced on treatment with oseltamivir or zanamivir for novel influenza A strain H1N1 whose treatment was stopped following negative microbiological tests for H1N1 on nasal swabs would be allowed to enrol in the study)
3. History of severe allergic reaction after previous vaccinations or hypersensitivity to any H1N1 vaccine component
4. Current egg allergy
5. Known or suspected impairment/alteration of the immune system
6. Disorders of coagulation
7. Immunosuppressive therapy, use of systemic corticosteroids for more than 1 week within the 3 months prior to enrolment
8. Receipt of blood, blood products and/or plasma derivatives or any immunoglobulin preparation within 3 months prior to enrolment
9. Intent to immunise with any other vaccine(s) against novel influenza A strain H1N1 throughout the study period
10. Participation in another clinical trial of an investigational medical product
11. Any condition which, in the opinion of the investigator, might interfere with the evaluation of the study objectives. Children with chronic, stable medical illnesses that do not result in immunosuppression (e.g., cerebral palsy, epilepsy, cystic fibrosis, congenital heart disease) will be allowed to participate in the study, unless these conditions will in some way interfere with the completion of study procedures. Children with conditions that may alter the immune response to vaccines (e.g., Trisomy 21) or will affect the ability to accurately describe adverse events (e.g., children over 5 years of age but with severe learning difficulties) will be excluded
