• Current or recent, acute or chronic medical conditions that in the opinion of the Investigator are clinically significant and/or unstable (such as illness exacerbations) within the preceding 30 days.
• History of any seizures, with the exception of a single febrile seizure.
• Self-reported or known seropositivity suggestive of acute or chronic viral infection for human immunodeficiency virus, hepatitis B or hepatitis C.
• Known or suspected congenital or acquired immunosuppressive conditions.
• Current or recent immunosuppressive or immunomodulatory therapy, as follows:
• Chronic or long-term systemic corticosteroids: ≥ 0.125 mg/kg/day of oral prednisolone or equivalent daily;
• Sporadic systemic corticosteroids: ≥ 0.5 mg/kg/day of oral prednisolone or equivalent for two or more short courses of > 3 days in the 3 months preceding vaccination;
• Antineoplastic chemotherapy or radiation therapy within the 6 months preceding vaccination.
• Note: Use of topical, inhalant or localised tissue injections of corticosteroids prior to administration of the Study Vaccine or throughout the study are acceptable.
• Administration of immunoglobulin and/or any blood products within the 3 months preceding vaccination, or planned administration during the study.
• Participation in a clinical trial or use of an investigational compound within 28 days prior to the first dose of Study Vaccine, or within 28 days after receiving the final indicated dose of Study Vaccine, or plans to enter a study during this period.
